Abstract

The invention discloses a steering system. The steering system comprises a steering control mechanism (10) and a steering transmission mechanism (20) which is connected with the steering control mechanism (10), wherein the steering control mechanism (10) drives the steering transmission mechanism (20) to rotate; the steering transmission mechanism (20) drives a left steering joint (11) to move; the left steering joint (11) comprises an upper lug (2), a lower lug (3) and a steering knuckle main body (3); a lubricating oil hole (8) is arranged on a bushing (7); the lubricating oil hole (8) is shaped like a hourglass, whose diameter at the middle section (81) is less than diameters at the two ends (82), in an axial direction; pin holes (5) in the upper lug (2) and the lower lug (3) are elliptic; and short axis diameters of the elliptic pin holes (5) are larger than the diameter of the bushing (7). Through the adoption of the steering system disclosed by the invention, good lubricating effect and high assembling precision can be achieved.

Description

technical field [0001] The invention relates to a steering system. Background technique [0002] In the steering system of the existing vehicle, the steering knuckle plays a vital role in the steering system as an indispensable important part. The existing steering knuckle is connected with the steering axle of the vehicle through a pin shaft, and is Connect the steering wheels of the vehicle. When steering is required, the driver turns the steering wheel to drive the steering mechanism to rotate, which in turn drives the steering transmission mechanism to rotate; the steering transmission mechanism is connected to the steering knuckle, and the rotation of the steering transmission mechanism will drive the steering knuckle to rotate at an angle relative to the steering bridge. The rotation of the steering knuckle drives the rotation of the vehicle tires, thereby realizing the steering of the vehicle. [0003] However, in the existing steering system, problems such as low a...
