Description

Technical Field

[0001] This utility model relates to the field of valve plate technology, and more specifically to an automotive shock absorber valve plate. Background Technology

[0002] During the operation of the shock absorber, the valve plates open and close in a timely manner according to the movement of the shock absorber piston, controlling the flow of damping oil or gas between different chambers, thereby generating damping force and reducing the vibration of the frame and body.

[0003] By changing the opening degree, number, shape, or orifice diameter of the valve plates, the damping characteristics of the shock absorber can be adjusted to adapt to different road conditions and driving conditions, providing a comfortable driving experience and stable handling performance. For example, when driving at high speeds, a larger damping force is needed to maintain vehicle stability, and the valve plates will adjust accordingly to reduce the flow of oil or gas; when driving over bumpy roads, the valve plates will appropriately increase the flow of oil or gas to provide a better cushioning effect.

[0004] Current automotive shock absorber valve plates are typically thin, circular sheets with a hole in the center for mounting on the shock absorber's piston or valve seat. They may have special designs around the perimeter, such as chamfers, grooves, or protrusions, to facilitate installation with other components or enhance sealing performance.

[0005] Circular valve plates require a certain circular space for installation. In situations where the internal space of a shock absorber is limited, this can restrict the layout and design of other components. For example, to allow sufficient installation space for the circular valve plate, the size of the shock absorber piston or cylinder may need to be increased, increasing the overall volume and weight of the shock absorber. Furthermore, to ensure good performance of the circular valve plate, high machining precision is required, necessitating the use of high-precision machining equipment and processes. For instance, the circumference, flatness, and thickness tolerances of the valve plate need to be strictly controlled; otherwise, the sealing performance and fitting accuracy between the valve plate and the valve seat may be affected, increasing processing costs and production difficulty. Utility Model Content

[0006] The purpose of this invention is to provide an automotive shock absorber valve plate to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model employs the following technical means:

[0008] A shock absorber valve plate for automobiles includes an end, a cantilever, and a tail. The end has a rectangular structure. The cantilever first contracts from the end to the tail and then gradually expands and connects to the tail. The tail has an arc-shaped ring structure. An oval-shaped vent groove is provided on the cantilever. Two sets of positioning holes are symmetrically provided in the end.

[0009] Furthermore, the end, cantilever, and tail are integrally formed, and the lower end of the end is provided with a limit groove and a positioning groove in sequence.

[0010] Furthermore, the length of the end is 17.00 mm and the width of the end is 3.95 mm.

[0011] Furthermore, the two ends of the ventilation groove are arc-shaped with arc radii of 2.80 mm and 4.50 mm respectively, and the smaller end of the ventilation groove is closer to the end.

[0012] Furthermore, the cantilever is arc-shaped in the middle and its two ends gradually expand outward and are connected to the end and tail respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model features a miniaturized design, which facilitates processing and production, effectively improves the ease of installation within the shock absorber's internal space, and allows for better utilization of the layout and design of other components, thereby reducing the overall size and weight of the shock absorber.
