Types of Shock Absorbers Used in Automotives

Shock absorbers are an important class of components in your car. They protect the vehicle and the passengers from the unwanted jerks or jolts, vibrations because of bumps and wholes on the road. They make the movement of the vehicle smooth and make the ride comfortable for the passengers. There are different kinds of shock absorbers available and each of them has a distinct function according to the need of the vehicle. We discuss briefly a few of them.

The basic twin tube

The twin tube contains two nested cylindrical tubes – the working tube and the reservoir. Both the tubes contain hydraulic fluid. A piston is inserted into the inner tube and the piston cap has tiny orifices for the hydraulic fluid to get displaced when the piston moves back and forth. Thus, the shock energy converted into heat and gets removed. Twin tube shock absorbers can be as follows:

Gas charged twin-tube

In this, nitrogen gas is used in the reservoir instead of the hydraulic fluid. This is a major improvement over the basic twin tube as it gets rid of problems like aeration and foaming and also hydraulic fluid dripping out of the pipe caused by the action of the piston. Due to this prevention, overheating is reduced largely.

Position sensitive damping

The position sensitive damping system contains two extra grooves, so that the piston moves freely on the tube, if the vehicle is running on a smooth surface. At the same time, it also restricts the movements when the vehicle moves in a bumpy surface, where the upward and downward movement of the piston occurs with more intensity. This new advancement in the dampening system enables car designers to manufacture shock absorbers according to the size, weight, maneuverability, etc. of the car.

Acceleration sensitive damping

Acceleration sensitive damping can change the difference between smooth and bumpy riding. It can also react to bumps individually. Acceleration sensitive damping is achieved by making some changes in the compression valve. The important thing to note here is that, this damping mechanism just does not improve on the regular ‘control versus comfort’ trade off, but eliminates it. It also highly reduces the pitch of the vehicle while braking and roll during turning.

The mono-tube

Unlike the bi-tube damper, the mono-tube shock absorber has no reservoir tube. There has to be an amount of displacement of the hydraulic fluid when the piston is pushed in. This is managed by making the fluid adaptable to pressures. This is achieved by filling the lower part of the tube with nitrogen gas. The hydraulic fluid and nitrogen gas are separated by a ‘floating piston’.

When the piston is pushed downward, pressure rises in the hydraulic fluid and nitrogen. However, as an act of displacement, the floating piston moves downward compressing the nitrogen gas.

Likewise, when the piston is pulled out, the hydraulic fluid flows with the piston and the floating piston is also lifted upwards. The resistance created this way offers outbound damping of the suspension.

Gift Ideas For the Automotive Obsessed

From big to small and short to tall, auto enthusiasts everywhere dream about auto parts. When you’re looking for a gift that will win them over every time, consider some of the following car accessories.

Leather seat covers are the perfect match to any interior. In addition to their rich, refined appearance, they protect your interior and resale value from coffee, soda and even sharp objects that can scratch, tear or leave permanent stains. They slip on and off in seconds, with no tools required, and are available for all seats and rows in your vehicle. Many models are even treated with water and stain repellents for complete spill protection.

It may sound strange, but when you’re an auto-enthusiast, a set of brake pads is actually an incredibly thoughtful gift. Like underwear and socks, brake pads are always guaranteed to eventually wear out. However, performance-grade brake pads surpass their lesser stock counterparts in durability by 20 – 40 percent. They’re engineered from high-tech composite materials and provide a direct replacement for those under-performing stock pads. And, if he’s a pro, you could even throw in a set of brake lines.

For the environmentally conscious guy on your list, you might consider the Green air filter. Environmentally friendly, a Green air filter is reusable and greatly reduces the number of disposable air filters that clog landfills. Plus, they have the added benefit of actually performing better than other aftermarket air filters by trapping more dirt and producing greater airflow, providing more power, longer engine life and better fuel economy.

When it’s dad on your list, you can’t go wrong with a set of headrest monitors, especially when he has young kids and drives long distances. These LCDs will keep the young ones occupied for hours with a wide range of input options, including DVD, iPod, MP3 player, game console or any other digital device. They conveniently connect through the front-mounted auxiliary jacks and they operate independently, eliminating the inevitable fight over High School Musical vs. Spider Man.

For the fixer-upper on your list, headers are guaranteed to blow him away…literally. Performance-grade headers allow the engine to breathe easier by increasing the efficiency with which spent gasses move through the tailpipe. They provide 10 – 25 more horsepower, coupled with added torque and throttle response-benefits sure to put a smile on his face! And, for even more power, couple a new set of headers with a cold air intake system. It force-feeds additional oxygen into the engine, streamlining horsepower and torque to improve gas mileage.

Fixing – Much More And Beyond Stereotype Auto Repairs

Nothing can match the freedom of owning your own vehicle. Besides making your daily transport easy and hassle-free, it helps you move about freely as you choose. While you enjoy your drives and live life to the fullest, it’s essential to remember that breakdowns can take place at the most inconvenient times, leaving your puzzled and stranded on a distant highway. One of the worst feelings on this planet happens when your car breaks out of the blue. Apart from being extremely hazardous, it’s challenging for you to find a repair shop that’ll fix your automobile to perfection.

Waiting idly when your car needs repair is not very advisable. Since your car is a massive investment, you must hire an auto technician as soon as possible. However, it’s often seen that people take the DIY approach instead of hiring a professional. Besides the obvious reason of saving money, people are often afraid of taking their car to a repair shop. Well, most owners feel hesitant about going for a professional auto restoration job – deception and harassments being the most common reasons.

Today’s car restoration agencies are just as much fun as visiting a dentist. But, the good news is that many shops today are removing the pain and distress out of the process. A lot of these agencies offer you coffee as you wait in the queue, and also give you appointments that suit your work schedule. That way, you can easily repair your car, without taking a day off from your work. To your immense delight, most of these shops are open even on weekends. Some of them offer maintenance and prevention packages as well. These packages generally consist of checkups of the most important automotive parts – transmission, brakes, engine, lights, starter and steering. Some packages may also include fluid replacements; transmission fluid, oil, antifreeze, washer, power steering and filter change. Some items that need regular checkups are battery, belts, pipes, water pump, brake lines, fuel lines, and the exhaust system.

As for the tyres, they are highly essential for the safe running of any automobile. Most of the car owners neglect the upkeep of their tyres, and don’t recognize when they wear out. What’s more, there are possibilities of over-inflated and under-inflated tyres as well. Besides incurring a lot of risks for you, it increases your fuel expenses as well. A proper maintenance check will make sure that the tyres have right air pressure and tread depth levels. With professional tyre tune ups, you’ll increase the life of your car wheels.

Nowadays, a lot of these repair centers offer the benefit of fixing an appointment over the Internet. You simply choose a specific time and date when you wish to drop the vehicle, and mention what type service you need. Some of them also offer courtesy drives to your residence or workplace. If the repair work takes more than a day or two, they may also offer rental car services. All in all, it’s a win-win situation for you. Today, car repair services are no more a headache or botheration; in fact, it’s a pleasing experience.

Innovations in Auto Glass

Having the opportunity to run a franchise company in the auto sector has been quite an interesting job indeed. During my time as the CEO of The Car Wash Guys we ran a small team of researchers who gathered industry information from where ever we could find it. One of the most interesting new inventions we found was remarkable.

Let’s discuss some new innovations in Auto Safety, which are currently in the news. One interesting invention we found to be interesting, as we have studied Ultra-Sonic Mini-Blind Cleaning as an add-on market for our Window Washing company is the HUD; Heads up Displays which can be projected onto the windshield of a vehicle and the de-ice units using focused frequencies that break up the ice as you drive. When ice forms on your windshield you cannot see anything and are 50 times more likely to hit something.

Now then before we start discussing this newest technology, let us talk about some of our previous discussions on this inter-related subject. HUD displays in racing, human computer interface and other uses.

This is happening as predicted: OSRAM supplies LEDs for BMW head-up display Compound Semiconductor – Bristol, UK The display can be programmed and is easy to read day or night in all conditions thanks to an Osram light sensor which automatically adjusts the brightness.

Now then lets discuss the issues of this newest technology, which has to do with clean windshields and getting rid of ice as you drive or off your car without scraping. And I suggested that we integrate all these systems into the SmartVehicle System with net-centric sensors a de-icing unit using high frequency bursts. A temperature system for controlling cabin comfort has a sensor on the windshield. Then disperses this other system. Depending on the frequency used to free the ice, it shouldn’t interfere with electronics. And how about the cross over applications to Private Jets, Airlines and Military for the HUD displays? Here is the Press Release Describing this technology:

“Ice Surface Development, Inc. Ice surface Development, Inc. (ISDI) is a development company, focused on Ice Technology. Our mission is to increase the value of our principal asset — the rights to Ice Technology developed by Dr. Victor Petrenko and owned by Dartmouth University. Our strategy for improving the value of this technology is by further advancing the proof-of concept for specific, high value applications. ISDI owns the exclusive rights to this extremely valuable and innovative technology for all motorized, land based vehicles world-wide. The applications ISDI is developing will improve the driving experience for industrial, commercial and consumer vehicle users by reducing safety risks, increasing productivity and eliminating the hassle of ice removal and loss of traction. The most significant applications include: de-icing of glass surfaces, and improving the grip of tires to ice and snow. The market is already showing considerable interest in de-icing. A J.D. Power and Associates report on emerging automotive technologies released this February 20, 2002 states:

“Heated windshield (windscreen) glass garners the highest interest among European consumers. Nearly 90 percent of consumers express strong interest in the feature, which evenly clears away ice, snow and frost from the front windshield within three minutes, improving visibility. Heated windshield glass was also well received by U.S. consumers, however, not to the same extent as by the Europeans.”

Our technology can actually outperform the hypothetical, emerging technology described to the over 6,000 participants in this study. Increased tire adhesion is an even newer, more revolutionary concept that will follow de-icing. ISDI has joined forces with the best expertise from the relevant disciplines to move these applications forward. We are also in active discussions with a handful of interested strategic investors to help us execute our financial strategy. The essence of the strategy is to advance the development within a time frame of relatively high shareholder returns. We believe this point will be reached for de-icing when we have completed sufficient prototyping work to demonstrate in very specific applications the functional, cost and industry safety requirements. This process is well underway. Our plan also calls for tire adhesion applications to follow by about 6 months. In this application we anticipate scaling up our 1/3 scale lab model to a full sized prototype and testing it in a larger variety of adverse conditions. Altering Ice adhesion – starting with de-icing Dr. Petrenko of Dartmouth, the world’s foremost expert on ice technology, has discovered how to radically alter the adhesion of ice to conductive surfaces, either increasing or decreasing depending on the application. In the de-icing example above, the initial action, 1, is to deliver a low energy electric impulse to the glass surface creating within a few seconds a non-adhesive barrier between the ice and glass.

The second action, 2, the dispersal of the ice, occurs immediately — creating an ice free surface. Our principal near term objective is to establish these de-icing applications for autos/trucks — including windshields, side and rear windows, external mirrors, headlights, wipers and perhaps bodies. In the above diagram, demonstrating our High Frequency Approach, the technology de-ices surfaces in 0°C to -30°C temperature range. Power requirements range from 0.25 kw/m2 to 4 kw/m2 depending on temperature and wind speed (up to 200mile/h). In low-wind conditions this de-icer keeps protected surfaces unfrozen at a power rate of 0.25 kw/ m2 to 0.3kw/m2. (These power requirements are well within a standard automobile power supply). The net effect is to initially de-ice and then maintain ice-free conditions for drivers, improving safety, convenience and driver/equipment productivity. Improving Tire Grip Our other significant application is improving the grip of tires on ice or snow. Again, this application of the technology has been proven in the lab, and is supported by a 1/3 scale prototype and testing rig, with an example of test data to the left indicating the increase in effective friction when power is applied. The adhesion of tires to ice have been magnified by as much as 20-fold, providing a grip on ice similar to asphalt or concrete.”

Jeep Grand Cherokee SRT8 – On and Off Road Exhilaration

Call it MOPAR madness or call it sheer, ingenious automotive marketing and engineering, but whatever you decide to call the Jeep Grand Cherokee SRT8, you must realize one thing: no production vehicle has effectively combined off road ruggedness with on road durability. Until the Grand Cherokee SRT8 came along that is. Yes, not since the GMC Typhoon has an SUV proven to be a highway dominator as well as an off road maven. However, the Jeep Cherokee SRT8 goes well beyond any 4×4 vehicle by delivering a versatile, pavement pounding, all-around SUV.

The folks at Chrysler’s Street and Racing Technology (SRT) group could not leave well enough alone. From the Neon to the Viper and from the 300C to the Ram pickup truck, no model has been too sacred to receive a proper work over from the team. First it was a bevy of Dodge models, then it was the Chrysler 300C, but no Jeep model had yet been targeted for the group’s overhaul. The Grand Cherokee however was past due as fond memories of the GMC Typhoon likely played a part in the decision to inject “SRT steroids” into a widely acclaimed Jeep model. Indeed, the SRT group knew that 0 to 60 in five seconds with the Grand Cherokee would beat the Typhoon’s numbers by about four tenths of a second, easily making the Jeep model the all time leader on the road as it is already off the road.

Much like the full size SRT cars sold by Dodge and Chrysler, a 6.1L Hemi V8 was the engine of choice for the SRT team tasked with building the beefy Jeep. With 420 h.p. and 420 lb.-ft of torque, the burly Hemi would serve duty in the Grand Cherokee SRT8 along with 20 inch Goodyear performance tires, Bilstein shocks, four piston Brembo brakes, a Quadra-Trac On-Demand four wheel drive system, and a capable five speed automatic transmission. Indeed, when the project was completed, the SRT8 was paired against the Porsche Cayenne SUV and the Jeep won!

If the SRT8 isn’t fast enough for you or if you want to experience a rich, deep tone while driving, then the aftermarket parts industry has just what you need.

Magnaflow Exhaust has developed a performance exhaust system that pairs well with the Grand Cherokee SRT8. Developed from airliner quality stainless steel, a Magnaflow Exhaust delivers more horsepower, frees up more torque, and provides a rich tone not found on the typical Jeep exhaust system.

When it comes to air intake systems, Dubair and Airaid have induction systems that work great with your engine. Dirt is filtered out and cool air is invited in to deliver more horsepower, enhanced torque, while offering a deep, throaty tone that is certain to inspire you.

Naturally, the Jeep Grand Cherokee SRT8 has something that neither the current day Porsche Cayenne or the long since past GMC Typhoon could offer: thorough off roading capabilities. Like all Jeep SUVs, the Grand Cherokee SRT8 is trail rated so you get the best 4×4 capabilities matched to its top notch road competency. A true competitor no matter where you take it: the Jeep Grand Cherokee SRT8.
