Friction plate structure steering column locking device

Abstract

The invention belongs to the technical field of light, medium and heavy trucks, and particularly relates to a steering column locking device with a friction plate structure. On the premise that small adjusting force is guaranteed, large holding force can be met, and the device has the advantages of being simple in structure, reliable in performance and the like. Comprising a support welding assembly, a flat washer, a friction plate, a gasket, an upper end fastening bolt and a fixing screw. A steering column is arranged between the two side plates of the support welding assembly. A first arc-shaped notch is formed in the support welding assembly, and a first round hole is formed in each of the two sides of the first arc-shaped notch in the support welding assembly; a second arc-shaped notch is formed in the friction plate, and a second round hole is formed in each of the two sides of the second arc-shaped notch in the friction plate; the upper end fastening bolt sequentially penetrates through the flat washer, the second arc notch of the friction plate, the gasket, the first arc notch formed by welding the support and the steering column from left to right and then penetrates out of the other side of the welded support. The fixing screws penetrate through the second friction plate round holes and then are fixed to the two sides of the notch formed by welding the support through threads.

Description

technical field [0001] The invention belongs to the technical field of light, medium and heavy trucks, and in particular relates to a steering column locking device with a friction plate structure. In particular, it relates to a locking device for adjusting the angle and height of a steering column for fixing the steering wheel of an automobile, and is also applicable to other different types of vehicle models. Background technique [0002] At present, common truck steering wheel adjustable inclination devices are divided into two types of locking mechanisms, automatic and manual. There are two automatic locking methods, electric and pneumatic, which are controlled by motors and cylinders respectively. Their structures are complex and expensive. Therefore, most of the locking mechanisms for variable inclination angles of heavy-duty truck steering wheels currently use manual locking structures. When the operating force of the manual locking structure handle is appropriate, t...
