    Light truck rear axle (driven Bridge) as a vehicle one of the four trains, carrying a full load of the light truck load and ground by the wheels, chassis and body-bearer for the suspension of the vertical, vertical edge , The horizontal force and torque, and the impact load; after the bridge (Drive Bridge) also convey transmission of the biggest torque, the bridge also bear a shell counterproductive torque.Car driver and the structure of the bridge design parameters in addition to the reliability and durability of the car with important influence, but also on the performance of motor vehicles such as the driving force of economy, ride through, maneuverability and stability actuator Has a direct impact. In addition, the light truck driver bridge in the assembly of motor vehicles is also covered various mechanical parts, components, sub-assembly, and other species up to the great assembly. For example, the drive includes the main bridge reducer, differential, the gear wheel drive (axle and wheel-reducer), shell and all kinds of gear Bridge.Visible from above, the car driver involved in bridge design mechanical parts and components of the very wide variety of these parts, components and assembly manufacturing to design to almost all the modern machinery manufacturingprocess.
    The efficient use of transmission slowdown in single-stage driver bridge has become a vehicle of the future development direction. Reference to the traditional paper-driven approach to the design of the bridge the light truck driver bridge design. This article first to identify the main components of the structure of the main design parameters and then refer to a similar drive the bridge structure, identified design programmes; Finally, the owners, driven bevel gear, Cone planetary gear differential, axle gear, the whole floating - Axle and the overall strength of the shell-bridge to check bearing
s and bearing the school life.
    This design has the following two problems, First will be the engine torqueoutput to force through universal drive shaft after the transfer to the wheels, toachieve better traction and steering wheel of the effective play, thereby enhancing the light truck traffic capacity. The second is the differential to transfer power on both sides of the axle at the same time, allowing both sides axle with a different rotation speed, the wheel as much as possible to satisfy both sides in the form of pure rolling for not moving equidistant to reduce the tyre friction with the ground.
    This design has the following advantages: Because the central slowdown insingle-stage driver Bridge, the bridge after making the whole structure is simple,simple manufacturing process, thus greatly reducing manufacturing costs. In addition, the spiral bevel gear reducer single-stage main bridge increased after the transmission efficiency, improved transmission reliability.
The most important feature of this design is: Lord reducer is not a conventional double-bevel gear surface, but a spiral bevel gear. Spiral bevel gear and other gear compared with the smooth work, noise and vibration on the merits, and its transmission efficiency can be as high as 99%.
