a steering column

Abstract

The invention relates to the field of mechanical technology, in particular to a steering column. A steering column, including a clamping gasket, a U-shaped bracket, a square bracket, a cam gasket, and a bolt. The trapezoidal groove on the inner side of the clamping gasket is nested on the left and right sides of the square bracket, the arc groove on the outer side of the U-shaped bracket is nested in the groove on the inner side of the cam gasket, and the bolts pass through the cam gasket, U-shaped bracket, clamping The spacer and the square bracket pass through from one side of the U-shaped bracket to the other side of the U-shaped bracket. Compared with the existing technology, the U-shaped bracket, the clamping gasket, the square bracket and the cam gasket of the new locking mechanism are adopted, so that the mating contact area between the parts is increased, and the locking effect is enhanced. Prevent tipping between the U-shaped bracket and the square bracket.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a steering column. Background technique [0002] The steering column of an automobile is an important part of the steering system of an automobile. The design of the steering column must meet certain operating comfort and safety. The indicators for evaluating comfort performance are the stiffness and frequency characteristics of the steering column, and the indicators for evaluating safety performance. is the collapse performance of the pipe string when it collides and collapses.

AI Technical Summary

Problems solved by technology

[0003] In the traditional four-way adjustable steering column, the locking mechanism generally uses the plane of the U-shaped bracket to compress the plastic gasket connected to the square bracket. When the bolt is pre-tightened, the U-shaped bracket and the square bracket are realized. Clamping connection, but requires a lot of pressure to clamp

When the bolt pre-tightening force is applied, due to the limited friction between the clamping gasket and the square bracket, the rotation between the U-shaped bracket and the square bracket cannot be prevented. When the external force on the square bracket exceeds the distance between the U-shaped bracket and the square bracket When the friction torque between the U-shaped bracket and the square bracket is tilted, the collapse performance of the steering column fluctuates greatly, and the safety performance is not good

[0004] If the NVH performance of the steering column is not good, the driver will feel the vibration of the steering wheel connected to the steering column is very obvious when the car is driving, which will seriously affect the comfort of operation
