Shenzhen drive shaft wholesale

    is provided with a vertical drive shaft receiving hole and a gear cavity, the gear cavity is connected to the lower end of the drive shaft receiving hole and is equipped with a bevel gear mechanism, which is used to transmit the power of the drive shaft For the propeller shaft, the drive shaft is supported in a bearing in the drive shaft accommodating hole for rotation, and the bearing is fixed and held in the drive shaft accommodating hole. The drive shaft supporting structure is characterized by: a bearing fixing element, which For holding the bearing in the drive shaft accommodating hole so that the bearing cannot move longitudinally in the drive shaft accommodating hole; and a cover element through which the drive shaft passes, The cover element is arranged above the bearing fixing element and closes the upper end of the opening of the drive shaft containing hole in a liquid-tight manner.

    Optimization of drive shaft structure

    The drive shaft relies on splines and taper shafts to cooperate with the planet carrier to transmit torque, and the taper fits often Since the eccentric bolts are loose and worn, they cannot transmit torque. Therefore, it is necessary to improve the structure of the drive shaft. The automatic selection of drive shaft is included. The taper part of the drive shaft is removed, and the drive adapter plate and the spline shaft are designed as two separate parts. The adapter plate is designed as an internal spline groove that matches the drive shaft spline, and the drive shaft spline is designed as a full-body spline to transmit torque. , The torque is completely transmitted by the cooperation of the spline shaft and the planet carrier, and the spline shaft will no longer cause stress concentration due to the variable cross-section and uneven strength of the tapered shaft, thereby improving the strength of the drive shaft.

    Car drive shaft

    The transmission device designed to drive the wheels is located at the end of the car’s drive train, and its function is to reduce the torque It is transmitted from the differential axle gear to the driving wheels. In the split drive axle and the steering drive axle, the transmission device for driving the wheels includes a half shaft and a universal joint transmission device, and a constant velocity universal joint is often used. The automatic selection of drive shaft is included. In general non-disconnected drive axles, the transmission device that drives the wheels is the half shaft. At this time, the half shaft connects the differential half shaft gear with the hub. On a drive axle equipped with a wheel reducer, a half shaft connects the side gear with the driving gear of the wheel reducer.

    The semi-axes of ordinary non-disconnected drive axles are divided into semi-floating, 3/4-floating and Three types of full floating. The semi-floating semi-axle is directly supported on the bearing placed in the inner hole of the outer end of the axle housing with a journal close to the outer end, and the end is fixed with the wheel hub by a journal with a tapered surface and a key, or with a flange It is directly connected to the wheel disc and brake drum). Therefore, in addition to transmitting torque, the semi-floating axle shaft must also bear the bending moment transmitted from the wheels. It can be seen that the load on the semi-floating semi-bearing is complex, but it has the advantages of simple structure, small mass, compact size, and low cost. It is used for cars and light trucks with smaller mass, better service conditions, and low load-bearing capacity.
