Problems solved by technology

[0002] At present, the upper and lower transmission shafts of the automobile steering column are connected by splines. Since the splines are made of metal materials, abnormal friction and wear will inevitably occur during sliding. As the wear deepens, the gap between the splines will increase Larger and larger, which will lead to torsional play in the steering column, the torsion play will affect the driving comfort and steering sensitivity
The non-metallic coating is added between the inner and outer splines of some existing steering columns, which can achieve the purpose of reducing metal friction and clearance, thereby slowing down the occurrence of the problem, but this method cannot realize automatic torsional clearance. eliminate

Embodiment Construction

[0036] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0037] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0038] The invention relates to a steering column transmission shaft, which includes an upper transmission shaft and a lower transmission shaft that are sleeved to transmit torque, and also includes a torque transmission mechanism sandwiched between the upper transmission shaft and the lower transmission shaft. The torque transmission mechanism includes a first torque transmission part fixedly clamped between the upper transmission shaft and the lower transmission shaft, and is rotatably clamped between the upper transmission shaft and the lower transmission shaft adjacent to the first torque transmission part The second torque transmission part, and the pretension part connec...

Abstract

The invention provides a steering column transmission shaft comprising an upper transmission shaft and a lower transmission shaft in a sleeved connection with the upper transmission shaft to transmit torque, and further comprises a torque transmitting mechanism clamped between the supper transmission shaft and the lower transmission shaft. The torque transmission mechanism is formed by a first torque transmission part fixedly clamped between the upper transmission shaft and the lower transmission shaft, a second torque transmission part capable of being rotationally clamped between the upper transmission shaft and the lower transmission shaft, and a pre-tightening part connected to the upper transmission shaft or the lower transmission shaft, and in a transmission connection with the second torque transmission part. By the use of dislocation between the first torque transmission part and the second torque transmission part, the upper and lower transmission shafts can be clamped and reverse gap formed between the upper and lower transmission shafts can be eliminated; and user effect of the steering column can be guaranteed.

Description

Technical field [0001] The invention relates to the technical field of automobiles, in particular to a steering column drive shaft. Background technique [0002] At present, the upper and lower transmission shafts of the automobile steering column are connected by splines. Because the splines are made of metal materials, friction noise and wear are unavoidable when sliding. As the wear deepens, the spline gap becomes larger. The larger the increase, the torsion gap will appear in the steering column, which will affect the driving comfort and steering sensitivity. The existing part of the steering column adds a non-metallic coating between the inner and outer splines, which can reduce the metal friction and gap, thereby reducing the occurrence of the problem, but this method cannot realize the automatic torsion gap. eliminate. Summary of the invention [0003] In view of this, the present invention aims to provide a steering column drive shaft to eliminate the torsion gap of the ...
