Abstract

The invention provides an automatic adjustment vibration reducer, and belongs to the technical field of automobiles. The automatic adjustment vibration reducer solves the technical problem that in an existing vibration reducer, the magnitude of resistance borne by a main piston cannot be adjusted according to vibration amplitude. The automatic adjustment vibration reducer comprises a main piston, a piston rod, an ascending one-way valve, a descending one-way valve and a hydraulic oil cylinder. A working oil cavity is formed in the hydraulic oil cylinder. The main piston is located in the working oil cavity. The lower end of the piston rod is fixedly connected with the main piston. Multiple lower damping oil holes are formed in the side wall of the lower portion of the hydraulic oil cylinder, and the lower damping oil holes are distributed in the axial direction of the hydraulic oil cylinder. The ascending one-way valve can block all the lower damping oil holes. Multiple upper damping oil holes are formed in the side wall of the upper portion of the hydraulic oil cylinder, and the upper damping oil holes are distributed in the axial direction of the hydraulic oil cylinder. The descending one-way valve can block all the upper damping oil holes. According to the vibration reducer, the magnitude of resistance borne during up-and-down movement of the piston can be adjusted according to the vibration amplitude, and a good vibration reduction effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to an automatic adjustment shock absorber. Background technique [0002] The hydraulic shock absorber uses hydraulic oil as the working medium and uses the viscous damping effect of the oil to form a certain pressure difference before and after the throttle port or valve, and convert the kinetic energy of the vibration into the pressure of the liquid to attenuate and absorb the vibration. At present, Hydraulic shock absorbers have been widely used, such as aircraft landing gear, various automobiles, motorcycles, ships and other equipment that need to be damped. Hydraulic shock absorbers have the following advantages: (1) The range of damping force is wide And change with the size of the vibration speed, because the oil is almost incompressible, so its stiffness can be very large, so the vibration damping force is large, so it belongs to the strong shock absorber; (2) The damping ch...
