Description

Technical Field

[0001] The invention relates to a steering knuckle, in particular to an automobile steering knuckle with a shock absorbing structure applied in the steering knuckle field. Background Art

[0002] The steering knuckle, also known as the "ram's horn", is one of the important parts of the steering axle of the car. It can make the car run stably and transmit the driving direction sensitively. 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 turn the car. When the car is running, it is subjected to variable impact loads, so it is required to have high strength.

[0004] Based on the above search, combined with the prior art, it is found that although the existing steering knuckle has a certain rigidity, it does not have a shock-absorbing structure. When the steering knuckle is working, it needs to be equipped with an additional shock absorber to work together. However, when the shock absorber of the car fails or leaks oil, causing the shock absorption capacity to drop significantly, the steering knuckle does not have a shock-absorbing mechanism, so the impact force from the front of the car will directly act on the steering knuckle, resulting in the breaking of the steering knuckle. Therefore, an automobile steering knuckle with a shock-absorbing structure is proposed to improve the above problem. Summary of the invention

[0017] As another improvement supplement to the present application, when the shock absorber connected to the outside of the ram horn body is damaged, the impact force on the ram horn body will increase instantaneously. At this time, the hydraulic oil inside the first buffer chamber will increase in pressure instantaneously, thereby quickly pushing up the sealing plate inside the second sealing groove, and pressing the hydraulic oil into the second buffer chamber with a larger capacity, thereby further improving the shock absorbing effect on the ram horn body, realizing the adjustable shock absorbing capacity of the shock absorbing structure inside the ram horn body, and making the ram horn body more applicable.

[0018] As another improvement of the present application, an alarm component is arranged inside the shock absorbing seat, and the alarm component includes a touch switch fixedly connected to the inner wall at the top of the second buffer cavity, and an alarm is fixedly connected to the outer wall at the top of the shock absorbing seat, and the alarm is electrically connected to the touch switch; the outer wall at the top of the circular plate is fixedly connected to a rotating seat, and the rotating seat is rotatably connected to a second movable rod, and the end of the second movable rod away from the rotating seat is rotatably connected to the first movable rod, and the end of the first movable rod away from the second movable rod is fixedly connected to a push plate, and the top outer wall of the push plate is fixedly connected to equidistantly distributed protrusions, and the top outer wall of the push plate is provided with equidistantly distributed guide holes, and the bottom outer wall of the push plate is fixedly connected to equidistantly distributed spoilers, and the cross-section of the spoiler is W-shaped, and an arc rod is fixedly connected to the inside of the second buffer cavity, and a first limiting groove is provided on the top of the arc rod, and one end of the first movable rod passes through one end of the first limiting groove, and a limiting rod is arranged inside the second buffer cavity.

The spoiler arranged under the push plate can increase the contact area with the hydraulic oil, so that the push plate can respond quickly to rise.

[0020] In summary, after adopting the above structure, the present invention has the following advantages compared with the prior art:

[0021] 1. The use of the above-mentioned shock-absorbing assembly can make the horn body itself have a certain shock-absorbing ability, and can effectively work with the shock absorber, thereby improving the comfort of the car when driving on bumpy roads. At the same time, when the shock absorber fails, it can effectively dampen the impact force of the front load of the car, further improving the service life of the horn body. Specifically, when the horn body is subjected to impact force, the first fixed plate, the second fixed plate and the first spring located inside the movable cylinder work together to absorb the impact force, effectively reducing the damage to the horn body caused by the impact force. At the same time, when the piston body under the second fixed plate is subjected to impact force, it will slide inside the shock-absorbing seat, so that the hydraulic oil inside the shock-absorbing seat can be squeezed into the first buffer cavity through the through hole, so that the impact force can be absorbed for a second time, further weakening the impact force. The cross-section of the through hole is I-shaped, which can play a good throttling role, ensuring the effect of the piston body on the second round of absorption of the impact force.

[0022] 2. The above-mentioned throttling assembly can be used to throttle the hydraulic oil inside the shock absorber seat, thereby increasing the resistance of the piston body to move inside the shock absorber seat, thereby improving the shock absorbing effect of the shock absorbing assembly and effectively extending the service life of the ram horn body. Specifically, in the process of the piston body moving toward the bottom of the shock absorber seat, the hydraulic oil will press the throttling block into the throttling groove, thereby achieving the sealing of the throttling groove, so that the hydraulic oil can be pressed into the first buffer chamber. When the piston body moves toward the direction close to the end of the shock absorber seat for reset movement, the hydraulic oil on the upper part of the piston body will press the throttling block open for throttling and decompression, thereby ensuring the shock absorbing effect of the reciprocating motion of the piston body.

[0023] 3. By adopting the above-mentioned adjustment component, when the shock absorber connected to the outside of the ram horn body is damaged, the impact force on the ram horn body will increase instantaneously. At this time, the hydraulic oil inside the first buffer chamber will increase in pressure instantaneously, thereby quickly pushing up the sealing plate inside the second sealing groove, and the hydraulic oil can be pressed into the second buffer chamber with a larger capacity, thereby further improving the shock absorbing effect on the ram horn body, realizing the adjustable shock absorbing capacity of the shock absorbing structure inside the ram horn body, and making the ram horn body more applicable.

During the rising process of the second movable rod 1110, the angle between the second movable rod 110 and the first movable rod 1109 becomes smaller. At this time, the first movable rod 1109 will The push plate 1104 is driven to rise as a whole, and the protrusion 1103 arranged on the top of the push plate 1104 can squeeze the touch switch 1102 to turn on the touch switch 1102. At this time, the alarm 1101 electrically connected to the touch switch 1102 will work immediately to realize the alarm work, reminding people that the shock absorber may be damaged, which plays a good warning role for people. The arc rod 1107 arranged under the push plate 1104 is arched, thereby improving the impact resistance of the arc rod 1107. The spoiler 1106 arranged under the push plate 1104 can increase the contact area with the hydraulic oil, so that the push plate 1104 can respond quickly to rise.

[0054] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
