Problems solved by technology

The input and output shaft combination is used as a connection transition structure, and it also includes multiple parts. The traditional input and output shaft combination is connected by sliding bearing clearance fit and a torsion bar. One end of the torsion bar is connected to the input shaft through a spline shaft. The other end needs to be drilled and reamed after being inserted into the output shaft to fasten the connection with the output shaft. The assembly process is cumbersome and the parts have many structures, resulting in higher processing costs.

Abstract

An input and output shaft combination and an assembling method thereof relate to the technical field of automobile electric steering devices and comprise an input shaft, an output shaft, a sliding bearing and a torsion bar, a spline shaft is integrally formed at the upper end of the input shaft, and a blind hole allowing the torsion bar to be inserted into is formed in the upper end of the splineshaft. The output shaft is provided with a through hole for the torsion bar to penetrate in in the axial direction, the upper portion of the spline shaft is annularly provided with a step, the lower end of the output shaft is provided with a step surface matched with the step, the circumferential surface of the upper end of the torsion bar is provided with an upper outer spline, and the circumferential surface of the lower end of the torsion bar is provided with a lower outer spline. The inner wall of the through hole is provided with a section of upper positioning hole which is used for pressing and clamping the upper outer spline and has the inner diameter smaller than that of the through hole, and the inner wall of the blind hole is provided with a section of lower positioning hole which is used for pressing and clamping the lower outer spline and has the inner diameter smaller than that of the blind hole; and the outer wall surface of the sliding bearing is connected with the innerwall surface of the through hole in an interference fit mode and is in clearance fit with the spline shaft. The number of parts can be reduced, cost is decreased, and assembling is convenient.

Description

technical field [0001] The invention relates to the technical field of electric steering devices for automobiles, in particular to an input and output shaft combination and an assembly method thereof. Background technique [0002] Automobile electric steering devices usually need to be connected to the steering wheel of the car through a combination of input and output shafts to receive the torque transmitted by the steering wheel of the car to complete the steering. The input and output shaft combination is used as a connection transition structure, and it also includes multiple parts. The traditional input and output shaft combination is connected by sliding bearing clearance fit and a torsion bar. One end of the torsion bar is connected to the input shaft through a spline shaft. shaft connection, the other end needs to be drilled and reamed after being inserted into the output shaft to fasten the connection with the output shaft. Contents of the invention [0003] The ...
