Problems solved by technology

[0004] After the adjustment handle 1 is released, the gap generated by the rotation of the cam I2 relative to the cam II3 will be distributed uncontrollably in the entire locking mechanism. If the gap distribution between the adjustment handle 1 and the left side of the ∩-shaped bracket 5 is too large, or When the adjustment handle 1 is loosened, an axial force is applied to the cam II3, and it is easy to make the slider of the cam II3 disengage from the chute, resulting in failure of the mechanism

Abstract

The invention relates to an adjusting and locking mechanism of a steering column. The adjusting and locking mechanism of the steering column is composed of an adjusting handle with a long bolt, a cam I, a cam II, an n-shaped support, a press block, a thrust bearing, a nut and the like, wherein the cam I and the cam II are matched. The adjusting and locking mechanism of the steering column further comprises an axial spring arranged between the press block and the thrust bearing. According to the technical scheme, an interval generated when the steering column is adjusted is controllable, and therefore a slide block of the cam II is prevented from being disengaged from a sliding chute and losing efficacy.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, and in particular relates to a steering column adjustment and locking mechanism Background technique [0002] With the improvement of people's requirements for car driving comfort, the steering column of most cars is designed to be adjustable, so that the driver can adjust the position of the steering wheel according to his own needs. [0003] The steering column adjustment locking mechanism of the prior art is as figure 1 As shown, the steering column adjustment mechanism includes an adjustment handle 1 with a long bolt 4, a pair of cam I2 and cam II3 that cooperate with each other, ∩-shaped brackets 5 located on both sides of the column, a pressure block 6, and a thrust bearing 7 and nut 8. When the adjustment locking mechanism is in the locked state, the tooth heights of the cam I2 and the cam II3 are opposite, and the cam II3 and the pressure block 6 press the ∩-shaped b...
