Background
An automobile steering column is an important component of an automobile steering system and is a steering mechanism for connecting a steering wheel and a steering gear. Steering columns conventionally have an adjustment system for length adjustment and/or height or inclination adjustment of the steering column. However, when the steering column is adjusted in length and height, there is some small clearance between the components of the steering column adjustment system due to tolerances in the fit and manufacturing. These small clearances are easily ignored because they do not affect the basic performance and function of the steering column. However, when the adjustment system is in an adjustable state, the manual adjustment of the height and/or length of the steering column by the driver may cause friction impact on each component, which may generate Noise, affect the NVH performance of the vehicle (Noise, Vibration, Harshness), affect the user evaluation, and leave an impression of poor product quality for the user.
Steering columns of the prior art have been disclosed with a damping device in their length adjustment system.
