Problems solved by technology

In essence, the damping effect in the shock absorber converts the vibration energy into other energy forms such as heat, which has the effect of dissipating energy. On the one hand, energy consumption and vibration reduction waste the driving power, and on the other hand, due to the heating of the structure, it will also cause other adverse effects

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 In the shown embodiment, the hydraulic shock absorber with variable inertial mass is mainly composed of a first vibration acting end 1, a valve 2, a second vibration acting end 3, a hydraulic cylinder 4, a flow meter 5, a hydraulic motor 6, a flywheel 7 and an electric shock absorber. Liquid regulating valve 8 and other components. Due to the utilization of the amplification effect of the hydraulic transmission composed of the hydraulic cylinder and the hydraulic motor, when the electro-hydraulic regulating valve is closed, the present invention can obtain a maximum magnification of the actual mass of the flywheel by 2π 2 S 2 r 2 / n 2 times the equivalent inertial mass, so a larger inertial mass of the shock absorber can be achieved with a smaller mass flywheel.

[0022] The electro-hydraulic regulating valve in the present ...

Abstract

The invention discloses a variable inertial mass hydraulic damper comprising a first vibration acting end (1), a valve (2), a second vibration acting end (3), a hydraulic cylinder (4), a flowmeter (5), a hydraulic motor (6), a flying wheel (7) and an electro-hydraulic adjusting valve (8), wherein the first vibration acting end (1) is connected with a piston rod of the hydraulic cylinder (4); the shell of the hydraulic cylinder (4) is connected with the second vibration acting end (3); two ends of the hydraulic motor (6) are connected with two ends of the hydraulic cylinder (4) to form a structure that the hydraulic cylinder (4), the hydraulic motor (6) and the electro-hydraulic adjusting valve (8) are connected in parallel; the valve (2) is arranged on a hydraulic pipeline; the flowmeter (5) is arranged on a hydraulic pipeline of the hydraulic motor (6); and the flying wheel (7) is connected with the output end of the hydraulic motor (6). The variable inertial mass hydraulic damper has simple structure, light weight, power energy source saving, low heating amount and favorable damping performance.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a semi-active hydraulic shock absorber with variable inertial mass. Background technique [0002] The semi-active shock absorber is a common shock absorber. According to different vibration signals, the vibration parameters of the shock absorber are adjusted by inputting a small amount of control energy, so as to achieve the purpose of vibration reduction. The adjustable vibration parameters in current semi-active shock absorbers mainly include stiffness and / or damping parameters. For example, Chinese patent 200510050430.5 discloses a hydraulic shock absorber with adjustable damping. According to different vibration excitation signals, the damping characteristics of the shock absorber are adjusted to achieve the effect of vibration reduction. Chinese patent 200720073828 discloses a shock absorber with variable stiffness, which reduces vibration by adjusting the stiffness characteristics of th...
