The structure characteristics of automobile transmission shaft
 Hits:       Date:13-03-23
Automotive drive shaft is essential in parts, like the human can not live without the arm automobile drive shaft is composed of shaft, telescopic sleeve tube and a universal joint. Telescopic sleeve can automatically adjust the change of the distance between the transmission and drive axle. Universal joint is to guarantee the transmission output shaft and the drive axle axis type axial Angle changes, and realize the two axis of constant speed drive. General and universal joint cross shaft, cross bearing and flange fork, etc. Steyr series heavy duty truck used with roller cross shaft universal joint drive shaft bearing, cooperate with short and thick cross shaft, can transfer bigger torque. In bearing end equipped with butterfly spring, pressure roller. Cross shaft end face increased with spiral groove of the reinforced nylon washers, to prevent big Angle or torque transmission power during sintering.
Has been added to the model in the flange spline shaft is a tubular sealed case, at the end of the cases set up two polyurethane rubber oil seal, the telescopic sleeve form plant in a fully enclosed space, the erosion of the flex spline shaft is not affected by external dust, dust and rust. So in spline shaft and the sleeve when it is assembled in one-time daub grease, it can completely meet the requirements, don't need to filling nozzle lubrication, reduces the maintenance content.
Drive shaft is a high speed, less bearing body of revolution, so its dynamic balance is crucial. General transmission shaft dynamic balance test should be in before they go out, and has carried on the adjustment on the balance. Therefore, a set of drive shaft is matching the factory, in use it should pay special attention to.
Heavy duty truck according to the drive form the different choice of different type of drive shaft. Generally 4 x 2 drive cars only in the form of a main transmission shaft. Drive in the form of a car has 6 * 4 middle, main shaft and transmission shaft, driving axle shaft. 6 x6 drive cars not only in the form of middle, main shaft and transmission shaft, driving axle shaft, and front axle drive shaft. In the middle of the long wheelbase vehicle drive shaft is equipped with the drive shaft center support in general. It is composed of supporting frame, and support. Traditional structure of the transmission shaft extension set is the spline set with welding flange fork, the spline shaft welded on the drive shaft tube. And GWB shaft changes the traditional structure of the company, the spline sleeve and the shaft tube welding as a body, the spline shaft and flange fork into an organic whole. And change the rectangle spline to short pressure Angle involute spline, it increases the strength and facilitate extrusion forming, meet the needs of the high torque conditions. In the pipe and the spline shaft teeth surface, the overall coated with a layer of nylon material, not only in
