Description

Technical Field

[0001] The utility model belongs to the technical field of steering knuckles, in particular to a high-speed stability belt-shaft steering knuckle. Background Art

[0002] The steering knuckle is one of the main parts on the steering axle of a car. It can make the car run stably and sensitively transmit the driving direction. The function of the steering knuckle is to bear the front load of the car, support and drive the front wheels to rotate around the kingpin to steer the car. When the car is driving, the steering knuckle is subjected to variable impact loads.

[0003] For example, when a car is traveling at high speed, wear may easily occur between the connections between the internal connectors of the car and the various parts of the steering knuckle, which in turn may cause friction between the various parts during the driving of the car, easily causing cracks in the steering knuckle, which is not conducive to the long-term and stable use of the steering knuckle and affects the stability and controllability during use. Therefore, improvements are now made to a high-speed stability steering knuckle with an axle. Utility Model Content

[0004] In order to overcome the above defects of the prior art, an embodiment of the utility model provides a high-speed stability belt shaft steering knuckle, which can reduce the wear on the connection through the vibration reduction component and improve the stability of the steering knuckle body during use, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a high-speed stability belt shaft steering knuckle, comprising a steering knuckle body, the outer surface of the steering knuckle body is provided with a steering connecting rod and a steering damper arm, one side of the steering damper arm is provided with a brake assembly connecting rod, the outer surface of the steering knuckle body is provided with a brake connecting rod, the steering connecting rod, the steering damper arm, the brake assembly connecting rod and the end of the brake connecting rod are all provided with mounting openings, the interior of the mounting opening is provided with a damping member, the damping member includes a fixing ring fixedly connected to the interior of the mounting opening, the inner wall of the fixing ring is provided with a plurality of spring rods, the exteriors of the plurality of spring rods are connected with a mounting sleeve, and a spring is sleeved between the mounting sleeve and the fixing ring.

[0006] Preferably, a shaft is provided at the left center of the steering knuckle body, a threaded neck is fixedly provided at the end of the shaft, and a mounting hole is opened inside the threaded neck.

[0011] The high-speed stability belt-shaft steering knuckle proposed by the utility model can bring the following beneficial effects:

[0012] 1. When the car is running at high speed, the inner wall of the mounting sleeve is frequently rubbed. At this time, the ball inside the mounting sleeve can play a sliding role when connected with the workpiece, thereby reducing the friction between the inner wall of the mounting sleeve and the component, which is beneficial to reduce the wear of the mounting sleeve and improve the stability of the connection.
