Variable-angle pneumatic adjusting tubular column

Abstract

The invention relates to a variable-angle pneumatic adjusting tubular column, which comprises a steering shaft, a mounting bracket, left and right supporting plates, left and right adjusting plates and an air cylinder, wherein the steering shaft is mounted in an inner hole of the mounting bracket; the left and right support plates are respectively positioned on two sides of the mounting bracket; the left and right adjusting plates are respectively positioned on the outer sides of the left and right supporting plates; a guide groove is formed in each support plate; adjusting bolts penetrating through the guide grooves are arranged between the adjusting plates and the mounting brackets; a long bolt penetrating through the guide grooves is arranged between the left adjusting plate and the right adjusting plate; a shifting rod is arranged at the piston rod end of the air cylinder; the other end of the shifting rod is arranged on the long bolt between two clamping blocks in a sleeving mode;a limiting plate is arranged between the supporting plate and the side wall of the mounting bracket; an angle limiting groove is formed in the middle of the limiting plate; the inner diameter of theangle limiting groove is gradually increased from top to bottom; and a limiting piece is arranged in the angle limiting groove. The variable-angle pneumatic adjusting tubular column has the advantagesof being convenient to operate, time-saving and labor-saving, and capable of adjusting different rotating angles at different heights.

Description

technical field [0001] The invention relates to a variable-angle pneumatic adjustment column, which belongs to the technical field of vehicle steering control devices. Background technique [0002] The steering column assembly of an automobile is a connecting part installed between the steering wheel and the steering gear. It is mainly used to control the direction of the car, transmit torque, and absorb the energy of the car when it hits. At present, the existing heavy-duty trucks are driven by multiple drivers in rotation to complete the long-distance driving. For drivers of different genders, heights, and body types, they put forward higher requirements for driving comfort. However, the adjustment angle of the existing steering column is fixed in the process of moving up and down, resulting in limited adjustment of the steering wheel position, which cannot meet the requirements of different drivers for the position of the steering wheel according to their own driving cond...
