Description

Technical Field

[0001] The utility model belongs to the field of steering knuckles, in particular to an anti-fracture steering knuckle. Background Art

[0002] The steering knuckle, also known as the "ram's horn", is one of the important parts in the steering axle of a car. It can make the car run stably and sensitively transmit the direction of travel. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheels to rotate around the kingpin to steer the car.

[0003] Nowadays, the steering knuckle can rotate freely when installed, so when the car is turning, if the driver uses too much force, the steering knuckle and the shaft connected to the steering knuckle will get stuck to each other, making the steering wheel unusable or even breaking. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides an anti-fracture steering knuckle.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: an anti-fracture steering knuckle, comprising a steering knuckle rod, one end of which is threaded, and the other end is fixed by a steering knuckle plate, characterized in that a buffer assembly is provided on the outer peripheral side of the steering knuckle rod close to the steering knuckle plate;

[0006] The buffer assembly includes a collar, a push block is fixed on the inner wall of the collar, two sliders are slid in the steering knuckle rod, a spring is installed between the two sliders, and the buffer effect is achieved by the push block abutting against the slider to compress the spring.

[0007] Optionally, a buffer cavity is opened on the outer peripheral side of the steering knuckle rod, the sliding block is located in the buffer cavity, and the collar and the push block are also located in the buffer cavity.

[0008] Optionally, blocks are fixed on both side end walls in the buffer cavity, wherein the length of the sliding block is greater than the distance between the two blocks, and the length of the pushing block is less than the length between the two blocks.

[0009] Optionally, a limiting cavity is further provided on the outer peripheral side of the collar, a limiting roller is movably connected in the limiting cavity, and the limiting cavity is arranged in a triangular shape.

[0010] Optionally, the height of the limiting cavity at the lowest point in the limiting roller is higher than the surface of the ring.

[0011] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Due to the setting of the buffer component, the setting of the collar can be used to limit the rotation angle of the steering knuckle while allowing it to rotate freely. When the spring is compressed to the limit, the driver will be unable to continue turning the direction, and the spring will also provide assistance during rebound, effectively preventing the driver from turning the direction too hard and causing the steering knuckle to get stuck or even break.

[0013] 2. By setting the limiting cavity, when the steering knuckle rod rotates to the limit, the limiting cavity will tend to roll on the inclined surface of the limiting roller, so that the collar can be installed more tightly and the collar can be effectively prevented from slipping.

[0019] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0020] As shown in Figures 1-4, an anti-fracture steering knuckle includes a steering knuckle rod 10, one end of the steering knuckle rod 10 is threaded, and the other end is fixed by a steering knuckle plate 11, characterized in that: a buffer component is provided on the outer peripheral side of the steering knuckle rod 10 close to the steering knuckle plate 11, and the buffer component includes a collar 12, and a limiting cavity 13 is also opened on the outer peripheral side of the collar 12, and a limiting roller 14 is movably connected in the limiting cavity 13, and the limiting cavity 13 is set in a triangular shape, and the height of the limiting cavity 13 at the lowest point in the limiting roller 14 is higher than the surface of the collar 12, and the inner wall of the collar 12 is fixed There is a push block 19, and two sliders 16 are also slidably arranged in the steering knuckle rod 10. A spring 17 is installed between the two sliders 16. The push block 19 abuts against the slider 16 to compress the spring 17 to achieve a buffering effect. A buffer cavity 15 is provided on the outer peripheral side of the steering knuckle rod 10, and the slider 16 is located in the buffer cavity 15. The ring 12 and the push block 19 are also located in the buffer cavity 15. Blocks 18 are also fixed on the end walls on both sides of the buffer cavity 15, wherein the length of the slider 16 is greater than the distance between the two block blocks 18, and the length of the push block 19 is less than the length between the two block blocks 18.

[0021] When in use, the steering knuckle rod 10 is first installed on the vehicle, and the collar 12 is interference-fitted on the automobile parts. Then, when the car turns, the steering knuckle rod 10 will be driven to rotate. Since the collar 12 is fixed, the rotation of the steering knuckle rod 10 is restricted by the block 18 on one side, and the slider 16 on the other side abuts against the push block 19 and compresses the spring 17. When the spring 17 is compressed to the limit, the driver will not be able to continue to turn the direction. During the rebound, the spring 17 will also provide assistance, effectively preventing the driver from turning the direction too hard and causing the steering knuckle to get stuck or even break. When the collar 12 is assembled on the automobile parts, the limiting cavity 13 is at the lowest point of the limiting roller 14. When the steering knuckle rod 10 rotates to the limit, the limiting cavity 13 will tend to roll on the inclined surface of the limiting roller 14, so that the collar 12 is installed more tightly, effectively preventing the collar 12 from slipping.

[0022] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
