Abstract

The invention provides an automobile steering wheel large-stroke pneumatic steering tube column which comprises an installing support assembly and a column tube. A plurality of groups of lower friction pieces are installed on two faces of the lower side of the installing support assembly, upper friction pieces are arranged on the column tube, gaps are formed among the upper friction pieces, an air cylinder is arranged on the column tube, an ejection rod of the air cylinder can push the upper friction pieces to deform, and accordingly the upper friction pieces tightly attach to the lower friction pieces. A rotary shaft bolt connected to the column tube and a sliding sleeve are installed in a sliding groove of the installing support assembly, and a control hinge pin connected to the column tube is installed in a steering wheel stroke control region of the installing support assembly. The automobile steering wheel large-stroke pneumatic steering tube column makes an adjusting angle of a steering wheel large and a vertical adjusting distance long. The adjusting demands for steering wheel comfortable positions of drivers different in gender, height and body type are met, and the tube column is convenient to control and light.

Description

technical field

[0001] The invention relates to the field of mechanical technology, in particular to a large stroke pneumatic steering column of an automobile steering wheel. Background technique

[0002] The driver of the car realizes the change of the direction of the vehicle by manipulating the steering wheel, and the manipulation of the steering wheel is the main control part that cannot be separated from the hand when driving the vehicle. The driver's grasp of the position of the steering wheel is the main factor for the driver's driving comfort.

[0003] When the driver gets in the car, he generally needs to adjust the relative position of the seat and the steering wheel according to his own physical condition; in general, the seat is adjusted in passenger cars; in commercial vehicles, the steering wheel is generally adjusted. For modern long-distance continuous transport cars, it is generally driven by multiple drivers in rotation. For switching between drivers of d...
