Problems solved by technology

The analysis and use of this structure show that it has the following disadvantages: first, the cross shaft universal joint has small transmission torque, low transmission efficiency, and low limit speed; The instantaneous angular velocity of the moving shaft is not synchronous, which changes the transmission speed and torque; the third is poor sealing, and the sliding spline pair is easy to wear

Embodiment Construction

[0010] The specific implementation will be described in detail below in conjunction with the drawings:

[0011] in figure 1 In an embodiment of the present invention shown, a ball cage and joint bearing combined universal joint drive shaft assembly includes a seven-channel ball cage universal joint 2, a three ball pin constant velocity universal joint 7, There is also a transmission shaft 4 with splines at both ends, an elastic retaining ring 1, a dust cover 3, and a clamp 5. The star sleeve of the seven-channel ball cage universal joint 2 is installed on the outer spline at one end of the transmission shaft 4 through an inner spline and is axially fixed by an elastic retaining ring 1. The three-pin frame of the three-ball-pin type constant velocity universal joint 7 is installed on the external spline at one end of the transmission shaft 4 through the internal spline and is axially fixed by the elastic retaining ring 1. A dust cover 3 and a clamp 5 are provided at the connecti...

Abstract

The invention relates to an automobile drive shaft assembly, comprising a rzeppa universal joint with seven raceways, a tripod constant velocity universal joint, a drive shaft with splines at the two ends, retainer rings, sealed covers and hoops, A starlike inner race of the rzeppa universal joint with seven raceways and a spider of the tripod constant velocity universal joint are respectively installed on the outer splines at the two ends of the drive shaft by inner splines and are axially fixed by the elastic retainer rings; and the dustproof covers and the hoops are arranged at the joints of the drive shaft and the universal joints. The automobile drive shaft assembly can bear axial displacement and angular displacement while transferring torque, not only can steadily, flexibly, reliably and accurately transfer motion and torque, but also is flexible in rotation, free from clamping stagnation and high in bearing capability. By integrating the universal joints by the drive shaft, sliding spline pairs are omitted, the universal joints have good sealability after adopting the dustproof covers and the service life of the drive shaft is prolonged.

Description

Technical field: [0001] The invention relates to an automobile drive shaft assembly, and more specifically to an automobile drive shaft assembly. Background technique: [0002] Automobile transmission shaft is an important component connecting transmission and drive axle in automobile transmission system. In the prior art, most of the transmission shaft adopts double flange fork type automobile transmission shaft, that is, through two cross-shaft universal joints and The sliding spline pair ensures the transmission torque, length and angle change of the transmission shaft. The analysis and use of this structure show that it has the following shortcomings: one is that the cross-shaft universal joint has low transmission torque, low transmission efficiency, and low limit speed; the other is that the cross-shaft universal joint will have the active shaft and slave The instantaneous angular velocity of the moving shaft is not synchronized, which changes the transmission speed and to...
