Abstract

The invention provides a steering system. The steering system comprises a steering manipulation mechanism, a steering transmission mechanism connected with the steering manipulation mechanism, a left steering knuckle (9) connected with the steering transmission mechanism and a steering axle connected with the left steering knuckle (9), wherein the left steering knuckle (9) comprises a steering knuckle body (91); a pin hole (95) is formed in the steering knuckle body (91); a pin shaft (96) is arranged in the pin hole (95); a lining (97) is arranged between the pin hole (95) and the pin shaft (96); a lubricating oil hole (10) is formed in the lining (97); the lubricating oil hole (10) is axially shaped as a sand glass of which the diameter of a middle section (11) is smaller than the diameters of both ends (12). The steering system provided by the invention can have a good lubricating effect, and the problems of unsmooth steering or local wear in a working process are avoided; further, a good steering effect is brought about and the satisfaction degree of the user experience is improved.

Description

technical field [0001] The invention relates to a steering system. Background technique [0002] The steering system of an existing vehicle includes a steering control mechanism, a steering transmission mechanism, a steering knuckle and a steering bridge; in the process of driving the vehicle, the driver turns the steering wheel, which drives the steering control structure to rotate, and then drives the steering transmission mechanism to rotate; The steering transmission mechanism is connected with the steering knuckle, the rotation of the steering transmission mechanism will drive the steering knuckle to rotate at an angle relative to the steering bridge, and the rotation of the steering knuckle drives the steering wheels of the vehicle to rotate, thereby realizing the steering of the vehicle. The steering knuckle and the steering bridge are connected through the pin hole and the pin shaft arranged on the steering knuckle. In order to avoid the wear of the steering knuckle ...
