Description

Technical Field

[0001] The utility model relates to the technical field of automobile shock absorbers, in particular to a buffer block of a shock absorber for an automobile. Background Art

[0002] With the increasing requirements of suspension systems and drivers and passengers for vehicle driving NVH in the automotive industry, the use environment of buffer block products and shock absorbers in various vehicles is also getting higher and higher. Since the buffer block is often restricted by the surrounding environment during the reciprocating motion of the shock absorber, it is necessary to produce products with a larger height-to-diameter ratio (usually: L / OD≤1.5), but the increase in the height-to-diameter ratio reduces the deformation stability of the product, resulting in poor product performance and distortion, resulting in a decrease in life verification or inability to use. Similarly, the increase in the height-to-thickness ratio (usually: L / T≤5) aggravates the stability of product deformation and makes the product unable to work normally. Leading to durable failure. Therefore, it is necessary to perform some treatment on the buffer block to improve its static and durability characteristics. At present, designers are usually helpless with high height-to-diameter ratios and large height-to-thickness ratios, and can only improve the durability problem by improving the surrounding conditions of the buffer block (such as changing related matching parts). However, the improvement of peripheral parts is often limited by the space requirements of the vehicle for the shock absorber, which makes it impossible to arrange the vehicle, reduces the layout efficiency of the vehicle, and makes it impossible to adjust and verify the vehicle in the best state. This constrains the vehicle's room for improvement. Utility Model Content

[0003] In view of this, in order to solve the above problems, the purpose of the utility model is to provide a vehicle shock absorber buffer block, comprising:

[0004] The buffer block body has a central through hole, the central through hole is coaxially arranged with the buffer block body, an annular groove is arranged on the outer wall of one end of the buffer block body, and the annular groove is arranged along the circumference of the buffer block body.

[0005] In another preferred embodiment, the inner wall of the annular groove is arc-shaped.

[0006] In another preferred embodiment, the bottom radius of the annular groove is R2-R4 mm.

[0007] In another preferred embodiment, the depth of the annular groove is 3-4 mm.

[0008] In another preferred embodiment, the central through hole includes a first channel portion and a second channel portion that are interconnected, one end of the second channel portion is connected to one end of the first channel portion, and the inner diameter of the second channel portion is gradually reduced from the other end to one end.

[0009] Due to the adoption of the above technical solution, the utility model has the following positive effects compared with the prior art: through the application of the utility model, a vehicle shock absorber buffer block is provided, and the setting of the annular groove makes the buffer block body more convergent, thereby avoiding damage caused by distortion of the product during compression, and when the buffer block body is compressed, it will not expand outward significantly, and at the same time, the compression residual height of the buffer block body is increased, thereby improving the durability and stability of the buffer block body.
