Problems solved by technology

[0004] In the above structure, due to the fitting tolerance and manufacturing tolerance among the components of the steering column adjustment system, there are some small gaps, so when the adjustment system is in an adjustable state, the driver's manual adjustment of the height and / or length of the steering column Adjustment will cause friction and impact of various components, which will generate noise, affect the NVH performance of the car (noise, vibration and roughness), affect user evaluation, and leave the impression of inferior quality to users

Abstract

The invention relates to an adjusting system of an automobile steering column. The system comprises a steering column sleeve, an upper support, a clamping support, a cam disc and a handle assembly andfurther comprises frequency sheets arranged between a side board of the upper support and the steering column sleeve, wherein one side face of each frequency sheet is fixedly installed on one of theupper support and the steering column sleeve, the other side face of each frequency sheet is a sliding surface, the other one of the upper support and the steering column sleeve is provided with a sliding fit surface in sliding fit with the corresponding sliding surface, and oil storage structures are arranged on the sliding surfaces or the sliding fit surfaces. Through arrangement of the frequency sheets, the inherent frequency of the whole system can be improved, so that noise caused by gaps of the fit tolerance and the manufacturing tolerance is reduced. Through arrangement of the oil storage structures, the time period required for filling lubricating oil can be greatly prolonged, and the lubricating oil even does not need to be filled in the whole service life of the product.

Description

technical field [0001] The invention relates to an automobile steering column, in particular to an automobile steering column capable of adjusting length and height. Background technique [0002] The automobile steering column is an important part of the automobile steering system, and it is the steering mechanism used to connect the steering wheel and the steering gear. Steering columns traditionally have adjustment systems for length adjustment and / or height or inclination adjustment of the steering column. [0003] figure 1 An exploded schematic diagram of an adjustment system for a steering column of an automobile according to the prior art is shown. Such as figure 1 As shown, the steering column adjustment system of an automobile includes a steering column cover 1 , an upper bracket 2 , a clamping bracket 3 , a cam plate 4 and a handle assembly, wherein the clamping bracket 3 is fixedly arranged on the outer wall of the steering column cover 1 . The upper bracket 2 ...
