Automotive lightweight begins from suspension

Automotive lightweight proposition in recent years has become a major world auto industry, which in energy conservation, improved fuel efficiency and other pressures, are increasingly showing lightweight development. The suspension system as an important part of the body, how to achieve lightweight vehicle development has become a problem can not be ignored, a variety of rubber suspension, less leaf spring, aluminum swing arm, application of new materials, such as new scheme has been applied more and more. The electronic, also with continuous improvement and improve the car structure and function, research vehicle vibration, the design of new electronically controlled suspension systems, vibration control to the lowest level is an important measure to improve the quality of the modern automobile.

Currently, the vehicle suspension system including vauxhall rods has been entered into the electronic controller to control the use of the era. Optimum use of the control method to obtain high performance damping effect, and energy consumption as low as possible is the main direction of the vehicle suspension system development. What is the car lighter? In fact, the car is lighter in ensuring the strength and safety performance of vehicles premise, as far as possible to reduce the car's curb weight, thereby increasing the power of the car, reducing fuel consumption and reduce exhaust pollution.

Experiments show that, if the automobile 10 percent weight reduction, fuel efficiency can be increased by 6% -8%; reduce automobile curb weight 100 kg per hundred km fuel consumption can be reduced from 0.3 to 0.6 liters; 1% reduction in vehicle weight, fuel consumption can be reduced 0.7 %. Currently, due to the need for environmental protection and energy saving, lightweight car has become the trend of the world automobile development. The overall structure of the car is analyzed and optimized to achieve streamlined automobile cars parts, and overall weight reduction; lightweight engine; transmission lightweight; lightweight suspension; lightweight body and attachments are currently implemented lightweight vehicle light quantized six aspects.
