The role of car axle drive axle

Car axle hydraulic drive axle of trailer axle, the driving force from the engine to the drive wheels to realize speed down increase torsion effect, change the direction of power transmission at the same time. Composed of drive axle of the main reducer, differential and half shaft, axle housing. For FF and FR drive axle installation location, structure, the difference between the FF: clutch, gearbox, main reducer, differential and drive axle components are installed in the transmission housing, is located in the front of the car, power passed to the front wheels. FR: the main reducer, differential and drive axle components installed in the drive axle casing, which, in the back of my car power transmitted to the rear wheels. To drive axle ( 1) Function: with turning and driving two functions. Has both general drive axle of the basic components, but also has to bridge the unique king pin, etc. ( 2) To the structure of the drive axle has both general and drive axle of the main reducer, differential and half shaft; Also has the general steering axle, king pin, and the steering knuckle of shell hub, etc. It is compared with the single drive axle, steering axle, the difference is that, due to need half shaft is divided into two sections, respectively called half shaft ( Connected to differential) And the outer half shaft ( Connected to the hub) , both with a constant velocity universal joint together. At the same time, the king pin and therefore is divided into two segments, respectively fixed on the universal joint of the spherical bearing. Steering knuckle hollow shaft neck make it, so that the outer half shaft through it. Steering knuckle for the connecting fork steering knuckle ball shell, satisfy the need of the steering, and adapted to the steering knuckle of a force. To drive axle is widely applied to the all-wheel drive off-road vehicle ( 3) Turned to the working process of the drive axle drive, in the middle of the bridge equipped with main reducer and differential. Half shaft inside and outside half shaft through the constant velocity universal joint together, there are flowers outside half shaft end system, it engages flange and half shaft. Torque when driven current bridge consists of the main reducer, differential to the inner half shaft, universal joint, outside half shaft and axle shaft flange, finally passed to the wheel hub, driving wheel rotation. To: steering knuckle by steering knuckle axis neck and steering knuckle shell bolting as a whole. Steering knuckle axis neck with two wheel hub bearing, with supporting wheel; Steering knuckle axis pressed bushing, within internal carotid wall of hole in half shaft bearing. The steering knuckle shell fluctuation two parts of both ends up and down the bold part of the king pin, and the stop pin, stop at the steering knuckle shell with a steering knuckle arm, upper cover under the steering knuckle shell bottom is equipped with. Grease by upper and lower nozzle after injection, respectively into the heart of the king pin oil duct, again from two side holes into the king pin and bushing, lubrication. Automobile steering, steering drag link pull the steering knuckle arm drive, steering knuckle swing around the king pin when the steering wheel can be subsequently deflection, so as to realize auto steering. Supports bridge bridge belongs to the driven bridge. Single bridge driven triaxial car, driving axle trailer designed to support bridge before the engine front drive axle is also supported bridge over the car's rear axle also belong to support the bridge.
