Problems solved by technology

However, due to the rigid connection, the vibration and torsion generated during the driving process of the vehicle are transmitted to the steering control system, so that the axial vibration and torsional vibration generated by the steering drive shaft are directly transmitted to the steering wheel, which will affect the driver's operating comfort. The adjustment spline needs to be fastened by bolts and other fasteners. Due to its low position and limited assembly space, assembly is difficult

Abstract

The invention discloses a length-adjustable steering transmission shaft component which comprises a first transmission shaft, a second transmission shaft and an elastic connecting sleeve, wherein an axial hole is formed in one end of the first transmission shaft; a connecting section is arranged at one end of the second transmission shaft and inserted in the axial hole and can move in the axial direction of the axial hole; and the first transmission shaft is sleeved with one end of the elastic connecting sleeve, and the second transmission shaft is sleeved with the other end of the elastic connecting sleeve. By the adoption of the provided length-adjustable steering transmission shaft component, the whole component does not need to be connected through fasteners such as bolts and nuts andis convenient to assemble, the whole size of the steering transmission shaft component is reduced, the assembly difficulty is reduced, meanwhile, it can be guaranteed that torque is reliably transmitted, the elastic connecting sleeve achieves a sealing effect, and external foreign matter is prevented from entering the axial hole.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a length-adjustable steering transmission shaft assembly used in an automobile steering system. Background technique [0002] The steering drive shaft is the transmission part that connects the steering wheel and the steering gear, and is an important part of the steering system of the car. The design of the steering transmission shaft must ensure that it can transmit torque reliably. [0003] At present, the steering wheel and the steering gear are connected together by a rigid steering shaft plus a sliding adjustment spline and a universal joint to ensure reliable transmission of torque, so that the driver's steering force acts on the steering gear to realize steering operation. However, due to the rigid connection, the vibration and torsion generated during the driving process of the vehicle are transmitted to the steering control system, so that the axial vibration and t...
