Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0032] attached figure 1 It is a three-dimensional structure diagram of an embodiment of the present invention. The device comprises a cooling fin 1, a liquid storage cylinder 2, a mounting base 3, a liquid injection device 4, a rocker arm 5 and the like. Among them, the cooling fin 1 is obliquely installed on the outer wall of the liquid storage cylinder 2, and the oblique axis forms an angle of 45 degrees with the axis of the liquid storage cylinder 2. The height H of the cooling fin is equal to the length of the blade (rotating blade 9 or fixed blade 7) (1~1 / 2) R. The mounting seat 3 fixedly connects the shock absorber with the vehicle body, and the end of the liquid storage cylinder 2 is...

Abstract

The invention discloses a vibration reducer for a vehicle. The vibration reducer comprises a liquid storage cylinder; a liquid injecting device is arranged on the outer wall of the liquid storage cylinder; a rocker arm is arranged at the end part of the liquid storage cylinder; a rotating shaft is arranged in the liquid storage cylinder, and is fixedly coated with a rotating ring; one end of the rocker arm is connected with the rotating ring, and the other end is connected with a suspension; the rotating ring is welded with a rotating blade; the rotating blade is thin in top and thick in root; fixed blades are respectively welded on the upper and lower sides of the inner wall of the liquid storage cylinder; through holes are formed in middles of the fixed blades; and diaphragm spring one-way valves are respectively arranged on the right side of the upper fixed blade and the left side of the lower fixed blade. The vibration reducer can provide excellent nonlinear damping force different from the damping force in anticlockwise travel and clockwise travel, is low in part machining process requirements, is low in cost, is excellent in heat dissipating performance, and has the functions of temperature compensation and liquid injection.

Description

technical field [0001] The invention relates to a vehicle shock absorber, which belongs to the technical field of auto parts. Background technique [0002] The shock absorber is one of the important assemblies on the car. Its main task is to accelerate the attenuation of the vibration of the wheel and the body (or frame), generate a damping force relative to the vibration, and convert the vibration energy of the body and the wheel into heat energy to improve the performance of the car. ride comfort and handling stability. [0003] There are many types of traditional automobile shock absorbers, among which two-way hydraulic cylinder shock absorbers are the most widely used vehicle shock absorbers. The two-way hydraulic cylinder shock absorber includes a liquid storage cylinder, a working cylinder, a piston, a connecting rod, shock absorber oil, seals, and an oil valve. Through the up and down movement of the piston connecting rod, the shock absorber oil repeatedly flows fro...
