Description

Technical Field

[0001] This utility model relates to the field of upper support devices for automotive front shock absorbers, and more particularly to an upper support device for automotive front shock absorbers. Background Technology

[0002] The upper support device of the front shock absorber is a key component connecting the shock absorber to the vehicle body. This type of support device usually adopts a structure of metal base with a single elastic component. The deformation of the elastic component absorbs the vibration transmitted by the road surface, while the metal base provides structural support to ensure that the shock absorber maintains a stable trajectory during vehicle operation.

[0003] However, some of these support devices used in passenger cars and small SUVs still have some shortcomings in actual use: First, the elastic elements are mostly made of homogeneous rubber, which can only buffer vibrations of some frequencies. When faced with high-frequency vibrations under complex road conditions, the shock absorption effect is not good, and the vibration is easily transmitted to the vehicle body, resulting in increased driving noise. In addition, the support structures at both ends of the device often experience local deformation due to concentrated stress. Especially after bearing the reciprocating force of the shock absorber for a long time, the structural stability decreases, shortens the service life of the device, and thus reduces the practicality of the device.

[0004] Therefore, those skilled in the art have provided a support device for a front shock absorber of an automobile to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a support device for a car front shock absorber. The device forms a composite buffer structure by opening honeycomb-shaped holes on the inner and outer walls of the rubber ring of the buffer mechanism and cooperating with the wave-shaped metal spring sheet on the upper end face. This allows the high-frequency vibration transmitted from the road surface to be efficiently absorbed, reducing the bumpy feeling during driving and improving the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A support device for a front shock absorber of an automobile includes a support device housing, a placement groove and a fixing hole. A buffer mechanism is provided at the upper end of the middle part of the support device housing. Both ends of the support device housing are provided with structural reinforcement mechanisms. The buffer mechanism includes a rubber ring. The outer and inner walls of the rubber ring are provided with multiple honeycomb-shaped holes. A wavy metal spring is provided on the upper end face of the rubber ring. Through the above technical solution, the device forms a composite buffer structure by opening honeycomb-shaped holes on the inner and outer walls of the rubber ring of the buffer mechanism and combining them with the wavy metal spring sheet on the upper end face. This allows the high-frequency vibration transmitted from the road surface to be absorbed efficiently, reducing the bumpy feeling during driving and improving the practicality of the device.

[0007] Furthermore, the structural reinforcement mechanism includes two outer metal rings, one end of which is fixedly connected to the inner wall of the outer metal rings, the other end of which is fixedly connected to the outer wall of the inner metal ring, and a cross-shaped reinforcing rib is fixedly connected to the outer wall of the inner metal ring and the inner wall of the outer metal ring. Through the above technical solution, the device improves the overall load-bearing capacity and structural stability by setting a structural reinforcement mechanism with metal partitions and cross-shaped reinforcing ribs at both ends of the support device shell, and by optimizing the fitting design of the fixing holes and bearing components, thereby effectively extending the service life and improving the practicality of the device.

[0008] Furthermore, a bearing assembly is fitted below the buffer mechanism, the outer ring of the bearing assembly is tightly fitted with the inner wall of the support device housing, and the bearing assembly uses ceramic rolling elements; Through the above technical solution, the ceramic rolling element reduces the rotational friction of the bearing assembly. Combined with the tight fit with the housing of the support device, it makes the bearing operation more stable and less prone to jamming.

[0009] Furthermore, an arc-shaped transition surface is provided at the connection between the inner wall of the support device housing and the placement groove, and the arc-shaped transition surface is cast from a wear-resistant alloy material. Through the above technical solution, the arc-shaped transition surface disperses the stress at the connection point, and the wear-resistant alloy material reduces wear in this area, extending the service life of the support device housing.

[0010] Furthermore, the inner wall of the fixing hole is provided with an annular groove, and an elastic rubber bushing is provided in the annular groove, with the inner wall of the bushing flush with the inner wall of the fixing hole. Through the above technical solution, the elastic rubber bushing can buffer the direct collision between the fixing bolt and the fixing hole, while filling the assembly gap, making the bolt installation more stable, and reducing the noise caused by bolt loosening.

[0011] Furthermore, carbon fiber short filaments are fixedly connected inside the rubber ring, and the carbon fiber short filaments are evenly distributed along the circumference of the rubber ring, forming an integral structure with the rubber ring. Through the above technical solution, the carbon fiber short filaments enhance the structural strength of the rubber ring, preventing the rubber ring from deforming or cracking under long-term pressure.

[0012] Furthermore, the top inner wall of the support device housing is provided with a stepped surface, and an elastic limiting pad is provided on the stepped surface, with the edge of the limiting pad tightly fitted to the inner wall of the support device housing; Through the above technical solution, the elastic limiting pad can limit the maximum compression stroke of the buffer mechanism, avoid damage caused by direct contact between components, and the tight fit also prevents the limiting pad from shifting during use.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figure 1-3 This utility model provides a specific implementation method: A support device for a front shock absorber of an automobile includes a support device housing 1, a placement groove 2, and a fixing hole 4. A buffer mechanism 3 is provided at the upper end of the middle of the support device housing 1. Structural reinforcement mechanisms 5 are provided at both ends of the support device housing 1. The buffer mechanism 3 includes a rubber ring 31. Multiple honeycomb-shaped holes 32 are opened on the outer and inner walls of the rubber ring 31. A wave-shaped metal spring sheet 33 is provided on the upper end face of the rubber ring 31. The device forms a composite buffer structure by opening honeycomb-shaped holes 32 on the inner and outer walls of the rubber ring 31 of the buffer mechanism 3 and cooperating with the wave-shaped metal spring sheet 33 on the upper end face. This allows high-frequency vibrations transmitted from the road surface to be efficiently absorbed, reducing the bumpy feeling during driving and improving the practicality of the device.

[0019] Reference Figure 3-6 The structural reinforcement mechanism 5 includes two metal outer rings 51. One end of a plurality of metal partitions 52 is fixedly connected to the inner wall of the metal outer ring 51. The other end of the metal partitions 52 is fixedly connected to the outer wall of the metal inner ring 53. The outer wall of the metal inner ring 53 and the inner wall of the metal outer ring 51 are fixedly connected to a cross-shaped reinforcing rib 54. By setting the structural reinforcement mechanism 5 containing metal partitions 52 and cross-shaped reinforcing ribs 54 at both ends of the support device housing 1, and optimizing the fitting design of the fixing hole 4 and the bearing assembly, the overall load-bearing capacity and structural stability of the device are improved, effectively extending the service life and thus improving the practicality of the device. A bearing assembly is fitted below the buffer mechanism 3. The outer ring of the bearing assembly is tightly fitted to the inner wall of the support device housing 1. The bearing assembly uses ceramic rolling elements, which reduces the rotational friction of the bearing assembly. Combined with the tight fit with the support device housing 1, the bearing operates more stably and is less prone to jamming. An arc-shaped transition surface is provided at the connection between the inner wall of the support device housing 1 and the placement groove 2. The arc-shaped transition surface is cast with wear-resistant alloy material. The arc-shaped transition surface disperses the force at the connection. In addition, the wear-resistant alloy material reduces the wear of this part and extends the service life of the support device housing 1. The inner wall of the fixing hole 4 is provided with an annular groove, and an elastic rubber bushing is provided in the annular groove. The inner wall of the bushing is flush with the inner wall of the fixing hole 4. The elastic rubber bushing can buffer the direct collision between the fixing bolt and the fixing hole 4, while filling the assembly gap, making the bolt installation more stable, and reducing the noise caused by bolt loosening. The rubber ring 31 is internally fixedly connected with carbon fiber short filaments. The carbon fiber short filaments are evenly distributed along the circumference of the rubber ring 31 and form an integral structure with the rubber ring 31. The carbon fiber short filaments enhance the structural strength of the rubber ring 31 and prevent the rubber ring 31 from deforming or cracking under long-term pressure. The top inner wall of the support device housing 1 is provided with a stepped surface, and an elastic limiting pad is provided on the stepped surface. The edge of the limiting pad is tightly fitted with the inner wall of the support device housing 1. The elastic limiting pad can limit the maximum compression stroke of the buffer mechanism 3, avoid direct contact between components and prevent damage. The tight fit also prevents the limiting pad from shifting during use.

[0020] Working principle: When the vehicle encounters bumps, the impact force from the road surface is first transmitted to the outer shell 1 of the support device. The honeycomb holes 32 on the inner and outer walls of the rubber ring 31 initially absorb the vibration through deformation. The wave-shaped metal spring 33 on its upper end deforms synchronously to assist in buffering. The carbon fiber short filaments embedded in the rubber ring 31 enhance the structural strength and prevent damage to the rubber. The bearing assembly below the buffer mechanism 3 rotates with the shock absorber. The ceramic rolling element reduces friction and ensures stable operation. The two ends of the support device outer shell 1 are distributed with force through the cooperation of the metal outer ring 51, metal partition 52, metal inner ring 53 and cross-shaped reinforcing rib 54, which improves the overall load-bearing capacity. The elastic rubber bushing in the fixing hole 4 buffers the vibration of the bolts and avoids loosening and noise. The elastic limiting pad at the top of the support device outer shell 1 limits the maximum compression stroke of the buffer mechanism 3 and prevents hard contact between components. The coordinated action of each structure achieves stable buffering and support.
