Description

Technical Field

[0001] The utility model relates to the technical field of front suspension coil springs of shock absorber assemblies, in particular to a front suspension coil spring of an automobile shock absorber assembly. Background Art

[0002] The front suspension coil spring of the shock absorber assembly is a key elastic element connecting the axle and the vehicle body.

[0003] The front suspension coil spring of the shock absorber assembly is mainly used to transmit vertical force and alleviate the impact and vibration caused by uneven road surface.

[0004] When the impact force of the road on the wheel is transmitted to the spring, the spring will deform, absorb the kinetic energy of the wheel, and convert it into elastic potential energy of the spring, thereby mitigating the impact of the ground on the vehicle body. However, in the existing technology, when the coil spring is deformed, the greater the deformation, the greater its elastic potential energy, resulting in a greater reverse thrust on the buffer pad. The buffer pad is prone to damage under long-term impact and needs to be replaced to ensure normal buffering effect, which is not conducive to normal use. Therefore, we propose a front suspension coil spring for an automobile shock absorber assembly. Utility Model Content

[0005] In response to the deficiencies in the prior art, the utility model provides a front suspension coil spring for an automobile shock absorber assembly, which solves the problem that when the coil spring is deformed, the greater the deformation, the greater its elastic potential energy, resulting in a greater reverse thrust on the buffer pad. The buffer pad is easily damaged under long-term impact and needs to be replaced to ensure normal buffering effect, which is not conducive to normal use.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A front suspension coil spring of an automobile shock absorber assembly includes a lower fork arm, the lower fork arm is fixedly connected to the front suspension beam, the top end surface of the lower fork arm is fixedly connected to a connecting tube and a shock absorber, and the interior of the connecting tube is provided with:

[0007] The shock absorbing unit includes a damper fixedly connected to the outer peripheral wall of the shock absorber, the damper is slidably connected to the inner wall of the connecting cylinder, and an upper coil spring and a lower coil spring are fixedly connected to both sides of the damper.

[0008] Preferably, a shock absorbing tube is fixedly connected to the top end surface of the lower fork arm.

[0009] Preferably, a connecting arm is fixedly connected to the outer wall of the shock absorbing tube, and the connecting arm is fixedly connected to the front suspension beam.

[0015] The utility model discloses a front suspension coil spring of an automobile shock absorber assembly, which has the following beneficial effects:

[0016] The front suspension coil spring of the automobile shock absorber assembly, when the car encounters a bump, the crossbeam moves to push the shock absorber downward, driving the damper downward, causing the damper to stretch the upper coil spring and compress the lower coil spring at the same time. When the car returns to stability, both the upper and lower coil springs tend to return to their initial states. Under the reaction of the upper and lower coil springs, the movement of the shock absorber is restricted to prevent it from moving too fast under the elastic potential energy of the spring, resulting in excessive impact on the damper and a shorter service life of the damper.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] The embodiment of the present application provides a front suspension coil spring for an automobile shock absorber assembly, which solves the problem that when the coil spring is deformed, the greater the deformation, the greater the elastic potential energy, resulting in a greater counter-thrust on the buffer pad. The buffer pad is easily damaged under long-term impact and needs to be replaced to ensure normal buffering effect, which is not conducive to normal use. When the car is bumpy, the crossbeam moves to push the shock absorber 4 downward, driving the damper 503 to move downward, so that the damper 503 stretches the upper coil spring 502 and compresses the lower coil spring 504. When the car returns to stability, the upper coil spring 502 and the lower coil spring 504 both tend to return to their initial state. Under the reaction of the upper coil spring 502 and the lower coil spring 504, the movement of the shock absorber 4 is restricted, preventing it from moving too fast under the spring elastic potential energy, resulting in excessive impact on the damper 503 and a shorter service life of the damper 503.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] The embodiment of the utility model discloses a front suspension coil spring of an automobile shock absorber assembly.

[0026] According to the attached Figure 1-3 As shown, it includes a lower fork arm 1, which is fixedly connected to the front suspension beam. The top end surface of the lower fork arm 1 is fixedly connected to a connecting tube 3 and a shock absorber 4. The interior of the connecting tube 3 is provided with:

[0027] The shock absorbing unit 5 includes a damper 503 fixedly connected to the outer peripheral wall of the shock absorber 4, and the damper 503 is slidably connected to the inner wall of the connecting tube 3. The upper coil spring 502 and the lower coil spring 504 are fixedly connected to the two sides of the damper 503 respectively. When the car is bumpy, the crossbeam moves to push the shock absorber 4 to move downward, driving the damper 503 to move downward, so that the damper 503 stretches the upper coil spring 502 and the damper 503 compresses the lower coil spring 504. When the car returns to stability, the upper coil spring 502 and the lower coil spring 504 both tend to return to their initial state. Under the reaction of the upper coil spring 502 and the lower coil spring 504, the movement of the shock absorber 4 is restricted to prevent it from moving too fast under the spring elastic potential energy, resulting in excessive impact on the damper 503, resulting in a shorter service life of the damper 503.

[0028] The top end surface of the lower fork arm 1 is fixedly connected to a shock absorbing tube 2, and shock absorption is performed under the action of the shock absorbing tube 2.

[0029] A connecting arm 201 is fixedly connected to the outer wall of the shock absorbing tube 2, and the connecting arm 201 is fixedly connected to the front suspension beam. Under the action of the connecting arm 201 and the lower fork arm 1, the connection between the connecting tube 3 and the front suspension beam is relatively stable.

[0030] The connecting arm 201 is rotatably connected to an upper fork arm 301 , and the upper fork arm 301 is rotatably connected to the outer wall of the connecting tube 3 .

[0031] The top end surface of the shock absorber 4 is fixedly connected to a connecting seat 401, which is connected to the automobile crossbeam. When the automobile is bumpy, the crossbeam moves to push the shock absorber 4 downward, driving the damper 503 to move downward.

[0032] The outer peripheral wall of the shock absorber 4 is slidably connected to a fixing seat 501 , and the fixing seat 501 is fixedly connected to the inner wall of the connecting tube 3 .

[0033] The fixing seat 501 is fixedly connected to one end of the upper coil spring 502 away from the damper 503 . When the damper 503 moves under the movement of the shock absorber 4 , the damper 503 stretches the upper coil spring 502 .

[0034] One end of the lower coil spring 504 away from the damper 503 is fixedly connected to the lower fork arm 1. When the damper 503 moves downward, the damper 503 compresses the lower coil spring 504. Under the action of the upper coil spring 502 and the lower coil spring 504, the damper 503 and the shock absorber 4 are used for buffering.

[0035] When the car returns to stability, the upper coil spring 502 and the lower coil spring 504 both tend to return to their initial states. Under the interaction between the upper coil spring 502 and the lower coil spring 504, the shock absorber 4 is driven to move upward. At the same time, under the reaction of the upper coil spring 502 and the lower coil spring 504, the movement of the shock absorber 4 is restricted to prevent it from moving too fast under the elastic potential energy of the spring, resulting in excessive impact on the damper 503, resulting in a shorter service life of the damper 503.
