Embodiment

[0016] Example :Such as figure 1 , figure 2 with image 3 As shown, a steering knuckle includes a steering knuckle body 1, on which an upper ear 11, a lower ear 12 and a journal 19 are arranged; Corresponding pin hole 13 is arranged, pin shaft 14 is installed in described pin hole 13, and bushing 15 is installed between described pin hole 13 and described pin shaft 14, and described bushing 15 is provided with Lubricating oil hole 16, said lubricating oil hole 16 is an hourglass shape in which the diameter of the middle section 17 is smaller than that of both ends 18 in the axial direction.

[0017] There are more than two lubricating oil holes 16 and they are uniformly arranged on the bushing 15 .

[0018] In this embodiment, the lubricating oil holes 16 are four and evenly distributed on the circumference of the bush 15 .

[0019] The diameter of the middle section 17 of the hourglass-shaped lubricating oil hole 16 is 0.5-2 mm, and the diameter of the two ends 18 of t...

Abstract

The invention provides a steering knuckle comprising a steering knuckle body (1), wherein an upper lug (11), a lower lug (12) and a shaft neck (19) are arranged on the steering knuckle body (1); pin holes (13) are correspondingly formed in the upper lug (11) and the lower lug (12) and are internally provided with a pin shaft (14); and a bushing (15) is arranged between the pin holes (13) and the pin shaft (14). The steering knuckle is characterized in that a lubricating oil hole (16) is formed in the bushing (15) and is in a sand clock shape (17) that the diameter of the middle section is less than those of two ends in the axial direction. The steering knuckle disclosed by the invention has a good lubricating effect, can be used for avoiding problems of unsmoothness of steering in a production process or local wearing, further the good steering effect is provided and the satisfying degree of user experience is improved.

Description

technical field [0001] The invention relates to a steering knuckle. 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. In order to avoid the wear of the steering knuckle and the pin shaft, a ...
