As the car to safety, energy saving, the constant attention to environmental protection, vehicle after vehicle bridge as a key component, the quality of their procts on the safe use of cars and car performance of a very large, so the car after Bridge Effectively optimize the design and calculation is very necessary.
Drive Bridge at the end of powertrain, its basic function is to increase came from the drive shaft or transmission of torque and power reasonably allocated to the left and right driving wheel and also bear in the role of the road and trailers or Body of power between the vertical and horizontal force. Drive from the main bridge general recer, differential and the wheels, transmission and drive axle components, such as Shell.
Bridge drive a vehicle with one of the four trains, its performance will have a direct impact on vehicle performance, and it is particularly important for the truck. Drive bridge should be designed to meet the following basic requirements:
a) a suitable main slowdown than to ensure that the car from the best power and fuel economy.
b) small form factor to ensure that the necessary ground clearance.
c) transmission gears and other parts of a smooth, noise.
d) in various load and speed of transmission with high efficiency.
e) to ensure adequate strength, stiffness conditions, should strive for the quality of small, in particular the quality of the spring as possible, to improve the car ride.
f) suspension and body-oriented movement coordination, the drive to the bridge, should also be coordinated with the campaign steering mechanism.
g) simple structure, processing technology and good, easy to manufacture, enables easy adjustment.

Abstract along with the automobile to the security, the energy conservation, the environmental protection unceasing takes seriously, the automobile rear axle of car takes a complete bikes's key component, its proct's quality to complete bikes's safety handling and the complete bikes performance's influence is very big, thus carries on the effective optimization design computation to the automobile rear axle of car is very essential. the driving axle takes automobile one of four big units, its performance quality immediate influence complete bikes performance, but appears regarding the truck especially important. When uses the uprated engine to output the big torque satisfies the present truck fast, the heavy load high efficiency, the high benefit need, must match one highly effective, the reliable driving axle. The driving axle generally by the main gear box, the differential device, the wheel transmission device and the driving axle shell and so on is composed. Will therefore use the transmission efficiency high single stage deceleration driving axle to become in the future the heavy load automobile's development direction. this article referred to the traditional driving axle's design method to carry on the truck driving axle's design. This article first determines major component's structure pattern and the main design variable; Then the reference similar driving axle's structure, determines the overall project design; Finally to the host, the driven bevel gear, the differential device circular cone planet gear, the rear axle shaft gear, the full floating axle and the integral-type bridge shell's intensity carried on the examination as well as has carried on the life examination to the supporting bearing. this design has the following merit: What because uses the central single stage deceleration driving axle, causes the entire rear axle of car the structure to be simple, the fabrication technology is simple, thus big reced the proction cost. And, the arc cusp gear's single stage main gear box raised the rear axle of car transmission efficiency, enhanced the transmission feasibility. key words: Driving axle main gear box differential device rear axle bridge shell
