Problems solved by technology

[0008] The solutions known today are bulky and their mechanisms are complex
The complexity of these mechanisms therefore also leads to the complexity of the implemented drive chain, the variety of mechanical connections of the drive chain leads to greater friction and thus to high electrical energy consumption

Embodiment Construction

[0053] Regardless of the embodiments of the transmission mechanism 40, board 13 is directly (such as through the teeth 44 of the board 13) or indirectly (via the intermediate components, such as small gears 45 meshing with the cam 11) around the reference axis X being driven.Along with the angle displacement, the board 13 was shifted by axial direction through the cam 11. Whether the cam is formed by the rotation can be moved, or the replacement ground can be carried by the component of the screw in the outer pipe 101.

[0054] The cam 11 plate 13 is rotated around the reference axis X of the coales of the ring body of the screw 12, and the drive arm 14 is rotated.The cam 11 supporting board 13 supports supporting the supporting parts 12, and the adjustment mechanism 10 is caused by the relative rotation of the two components 11 and 12 relative to each other.In particular, Board 13 revolves around the axis of the reference axis X in the front direction to generate the axial displa...

Abstract

The invention relates to a sleeve (103) of a steering column, comprising two elements consisting of an outer tube (101) and an inner tube (102), and an adjustment system (100) for adjusting a resistance against a relative translational movement between the two elements (101, 102), the adjustment system (100) comprising: at least one friction pad (20) supported by a first element (101) of the two elements (101, 102); a clamping surface (30) connected to a second element (102) of the two elements (101, 102), wherein the friction pad (20) is configured to contact and support on the clamping surface (30); an adjustment mechanism (10) comprising a cam (11) which is supported directly or indirectly on a support in order to generate a pressure change of the friction pad (20) against the clamping surface (30) parallel to a reference axis (X) fixed with respect to a first element (101) of the two elements (101, 102), the invention relates to a sleeve (103) for a steering column, comprising two elements (101), in order to vary the pressure exerted by a friction pad (20) on a clamping surface (30) of a second element (102) of the two elements (101) between a use position and an adjustment position, an adjustment mechanism (10) of the adjustment system (100) is configured to generate the relative rotational movement between the cam (11) and the support (12) about the reference axis (X).

Description

Technical field [0001] The invention generally involves the technical field of regulating systems used to regulate the resistance of the relative translation of two components. [0002] The present invention is more specifically involved in regulating the regulating system of the resistance of the two components (the two components is specifically composed of the external pipe and the internal pipe of the internal tube of the converter column's sleeve), so as to allow the vehicle to adjust the vehicle to adjust the vehicle(For example, a motor vehicle), the position of the steering wheel (eg). Background technique [0003] Thanks to the adjustment system controlled by vehicle users, the depth and height of the steering wheel of motor vehicles are often adjustable.This adjustment system usually includes a regulatory mechanism on the steering column of motor vehicles and can be manual or electrical.In the case of the electrical system, a component composed of a worm reducer associa...
