Description

Technical Field

[0001] This utility model relates to the field of control arm rubber sleeve technology, specifically a high-performance rubber sleeve for control arms. Background Technology

[0002] The control arm bushing is a rubber bushing fixed to the suspension and wheel positions. It plays a role in stabilizing the ride. When a car is driving on an uneven road surface, the wheels will bounce up and down, and the control arm will also move up and down accordingly. In order to cushion this movement and reduce noise and mechanical wear, a rubber bushing is needed as a connecting and cushioning component.

[0003] In the existing technology, as the vehicle is used for a long time and the mileage increases, the control arm bushing will age. The aged bushing may crack, deform and other phenomena, resulting in a decline in its function. Once the bushing ages, it will affect the shock absorption effect of the suspension system, causing unnecessary vibration and noise during the car's operation. Severely aged bushings may also cause misalignment of the front wheels, accelerate the wear of tires and related components, and increase additional maintenance costs. In addition, the control arm bushing is usually located at the bottom of the car and is covered by other parts, so routine inspection is difficult. Car owners usually need to go to a professional repair shop for a lift inspection to find out if there is a problem with the bushing.

[0004] To address this, a high-performance rubber sleeve for control arms is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-performance rubber sleeve for a control arm to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-performance rubber sleeve for a control arm, comprising a control arm body, an outer shell fitted onto the inner wall of the control arm body, a second elastic body fixedly connected to the inner wall of the outer shell, an inner bushing fixedly connected to the inner wall of the second elastic body, a first elastic body fixedly connected to the inner wall of the inner bushing, and a plurality of first reinforcing ribs for increasing mechanical strength fixedly connected at equal intervals to the outer wall of the inner bushing, wherein the side of the plurality of first reinforcing ribs away from the inner bushing is fixedly connected to the inner wall of the outer shell.

[0007] Preferably, a plurality of second reinforcing ribs are equidistantly distributed between the outer shell and the inner bushing, the second reinforcing ribs and the first reinforcing ribs are staggered, the outer walls of the second reinforcing ribs are all fixedly connected to the inner wall of the second elastic body, and a plurality of third reinforcing ribs are equidistantly fixedly connected to the inner wall of the first elastic body.

[0008] Preferably, the first reinforcing rib is arranged in a filament shape, the second reinforcing rib is arranged in an elliptical sphere shape, and the third reinforcing rib is arranged in a ring shape.

[0009] Preferably, the top of the outer shell is provided with a sliding groove, and a first arc-shaped plate and a second arc-shaped plate are slidably connected to the top of the outer shell respectively. The first arc-shaped plate slides vertically in the sliding groove, and the second arc-shaped plate slides horizontally in the sliding groove. A flexible mirror is fixedly connected to the concave part of the first arc-shaped plate, and a pair of return springs are fixedly connected to the bottom of the first arc-shaped plate. The end of the return spring away from the first arc-shaped plate is fixedly connected to the inner wall of the outer shell.

[0010] Preferably, a perforated strip is fixedly connected to the top of the second arc-shaped plate, and a rotating sleeve is fixedly connected to the side of the top of the second arc-shaped plate away from the first arc-shaped plate, and a hemispherical shell is rotatably connected to the top of the rotating sleeve.

[0011] Preferably, the sides of the first arc-shaped plate and the second arc-shaped plate that are close to each other are inclined relative to the outer shell, and the inclined surfaces of the first arc-shaped plate and the second arc-shaped plate are complementary.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting the first reinforcing rib in the form of filaments, the range of torque that the second elastic body can withstand during torsion is increased. Combined with the setting of the second reinforcing rib in the form of an ellipsoidal sphere, the vibration and extrusion forces on the second elastic body are effectively distributed to the second reinforcing rib, improving the uniformity of the force on the second elastic body. Similarly, the setting of the third reinforcing rib in the form of annular rings can also distribute the torque and vibration and extrusion forces on the first elastic body, thereby increasing the stress performance of the first and second elastic bodies, extending their service life, and reducing additional maintenance costs.

[0014] 2. By pressing and pushing the second arc-shaped plate towards the first arc-shaped plate, since both the first and second arc-shaped plates are inclined relative to the outer shell on the side closest to each other, and their inclined surfaces are complementary, the second arc-shaped plate can press the first arc-shaped plate away from the outer shell, stretching the return spring and causing the soft mirror to move to the top of the outer shell. At this time, the car owner can directly observe the soft mirror to understand the condition of the second and first elastic bodies, effectively reducing the difficulty of daily inspections.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 The present invention provides an embodiment of a high-performance rubber sleeve for a control arm, comprising a control arm body 1, an outer shell 2 fitted onto the inner wall of the control arm body 1, a second elastic body 10 fixedly connected to the inner wall of the outer shell 2, an inner bushing 3 fixedly connected to the inner wall of the second elastic body 10, a first elastic body 9 fixedly connected to the inner wall of the inner bushing 3, and a plurality of first reinforcing ribs 11 for increasing mechanical strength fixedly connected at equal intervals to the outer wall of the inner bushing 3, wherein the side of the plurality of first reinforcing ribs 11 away from the inner bushing 3 is fixedly connected to the inner wall of the outer shell 2;

[0025] Multiple second reinforcing ribs 12 are equidistantly distributed between the outer shell 2 and the inner bushing 3. The second reinforcing ribs 12 and the first reinforcing ribs 11 are arranged alternately. The outer walls of the second reinforcing ribs 12 are all fixedly connected to the inner wall of the second elastic body 10. Multiple third reinforcing ribs 13 are equidistantly fixedly connected to the inner wall of the first elastic body 9.

[0026] The first reinforcing rib 11 is arranged in a filament shape, the second reinforcing rib 12 is arranged in an elliptical sphere shape, and the third reinforcing rib 13 is arranged in a circular ring shape;

[0027] The filamentous first reinforcing rib 11 increases the range of torque that the second elastic body 10 can withstand during torsion. Combined with the ellipsoidal second reinforcing rib 12, it ensures that the vibration and extrusion forces on the second elastic body 10 are effectively distributed to the second reinforcing rib 12, thereby improving the uniformity of the force on the second elastic body 10. Similarly, the annular third reinforcing rib 13 can also disperse the torque and vibration and extrusion forces on the first elastic body 9, thereby increasing the stress performance of the first elastic body 9 and the second elastic body 10.

[0028] The top of the outer shell 2 is provided with a sliding groove 16. A first arc plate 6 and a second arc plate 8 are slidably connected to the top of the outer shell 2. The first arc plate 6 slides vertically in the sliding groove 16, and the second arc plate 8 slides horizontally in the sliding groove 16. A soft mirror 14 is fixedly connected to the concave part of the first arc plate 6. A pair of return springs 15 are fixedly connected to the bottom of the first arc plate 6. The end of the return spring 15 away from the first arc plate 6 is fixedly connected to the inner wall of the outer shell 2.

[0029] The top of the second arc plate 8 is fixedly connected to a perforated strip 4, and the top of the second arc plate 8 is fixedly connected to a rotating sleeve 7 on the side away from the first arc plate 6. The top of the rotating sleeve 7 is rotatably connected to a hemispherical shell 5.

[0030] The first arc plate 6 and the second arc plate 8 are both inclined relative to the outer shell 2 on the side that is close to each other, and the inclined surfaces of the first arc plate 6 and the second arc plate 8 are complementary.

[0031] Specifically, the second arc plate 8 pushes and moves towards the first arc plate 6. Since the first arc plate 6 and the second arc plate 8 are both inclined relative to the outer shell 2 on the side that is close to each other, and their inclined surfaces are complementary, the second arc plate 8 can push the first arc plate 6 away from the outer shell 2, stretching the return spring 15, so that the soft mirror 14 moves to the top of the outer shell 2. At this time, the car owner can directly observe the soft mirror 14 to understand the situation of the second elastic body 10 and the first elastic body 9.

[0032] The working principle of the above embodiment is as follows: When the car is running, the car body will vibrate. The control arm body 1 may drive the outer shell 2 to twist back and forth continuously, while the inner bushing 3 is fixedly connected. Therefore, the second elastic body 10 and the first elastic body 9 will be continuously subjected to vibration, compression and torsional forces. Through the setting of the filamentous first reinforcing rib 11, the range of torque borne by the second elastic body 10 during torsion is increased. With the setting of the ellipsoidal second reinforcing rib 12, the vibration and compression force on the second elastic body 10 is effectively distributed to the second reinforcing rib 12, improving the uniformity of the force on the second elastic body 10. Similarly, the setting of the annular third reinforcing rib 13 can also distribute the torque and vibration and compression force of the first elastic body 9, thereby increasing the stress performance of the first elastic body 9 and the second elastic body 10 and extending their service life. In addition, when the car owner wants to check the first elastic body 9 and the second elastic body 10, the first elastic body 9 can be adjusted accordingly. When the body 10 is damaged, the hemispherical shell 5 can be squeezed and pushed using an external long rod-like tool. Since the hemispherical shell 5 can rotate, when the force point is found, it is necessary to use the push bar 4 to squeeze and push the second arc plate 8 towards the first arc plate 6. Since the sides of the first arc plate 6 and the second arc plate 8 that are close to each other are inclined relative to the outer shell 2, and their inclined surfaces are complementary, the second arc plate 8 can squeeze the first arc plate 6 away from the outer shell 2, stretching the return spring 15, so that the soft mirror 14 moves to the top of the outer shell 2. At this time, the car owner can directly observe the soft mirror 14 to understand the condition of the second elastic body 10 and the first elastic body 9. After the inspection is completed, the pressure on the second arc plate 8 is released, and the elastic force of the return spring 15 makes the first arc plate 6 and the second arc plate 8 return to their original positions, effectively reducing the difficulty of daily inspection.
