Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steering knuckles, in particular to a steering knuckle. Background Art
[0002] The steering knuckle, also known as the "ram's horn", is one of the important parts of the car's steering axle, which can make the car run stably and sensitively transmit the driving direction. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to make the car turn.
[0003] After searching, the patent announcement number CN216833890U discloses a shock-absorbing automobile steering knuckle, which relates to the technical field of automobile steering knuckles, including a steering knuckle body, the interior of the steering knuckle body is inlaid with a flange, and the top of the flange is connected to a boss, the bottom of the boss is externally sleeved with an annular rubber ring, and the outside of the annular rubber ring is sleeved with a circular ring, and the surface of the circular ring is provided with a circular opening. In the utility model, by providing a folding rubber sleeve, a circular ring, an annular rubber ring, a ball, and a sponge strip, the folding rubber sleeve provides a buffering and shock-absorbing function for the connection between the steering knuckle and the automobile, and then, by the action of the circular ring, the ball and the annular rubber ring, the friction coefficient between the connection between the steering knuckle and the automobile is reduced, and at the same time, the sponge strip inside the annular rubber ring stores and absorbs lubricating liquid, so that the sponge body provides the ball and the boss with a lubricating liquid function, which is conducive to improving the practicality of the steering joint.
[0004] In the prior art, CN216833890U stores and absorbs lubricating liquid through the sponge strip inside the annular rubber ring during use, so that the sponge body provides lubricating liquid for the ball and the boss, which is beneficial to improving the practicality of the steering connection. However, in actual use, the ball is easily pressed for a long time and easily falls off, so it is necessary to limit the position, and when it is installed, the installation hole is easily squeezed and vibrated for a long time, so it needs to be improved.
