Electronic shock absorber

Abstract

The invention discloses an electrically-controlled shock absorbing mechanism which comprises two bearing oil cylinders, a variable pump, an oil tank, an energy accumulator and a control unit. According to the electrically-controlled shock absorbing mechanism, the flow of pressure oil is utilized for buffering shocks. More importantly, the electrically-controlled shock absorbing mechanism has the following two effects: a buffer function is achieved when the pressure oil in rodless cavities flows to the energy accumulator; and a first one-way valve is controlled through a pressure controller, thereby controlling the connection and disconnection of the rodless cavities and the energy accumulator. Therefore, by adoption of the electrically-controlled shock absorbing mechanism, moving equipment can not only run smoothly on a flat road, but also achieve the shock buffer function on a bumpy road by controlling the first one-way valve to allow the pressure oil to flow.

Description

technical field [0001] The invention relates to the technical field of electromechanical control, in particular to an electronically controlled damping mechanism. Background technique [0002] In the process of carrying mobile equipment, the road surface on which the mobile equipment travels is not absolutely flat, especially on dry soil roads. The mobile equipment transported with load will have an impact on the mobile equipment on the uneven road surface. This causes wear and tear on components in the mobile device. [0003] In order to prevent the mobile equipment from driving on uneven roads, the road will have a severe impact on the mobile equipment and damage the components. A shock absorbing mechanism is installed between the chassis and the tires of the vehicle. The shock absorbing mechanism is used to buffer the above impact, thereby slowing down Vibration of mobile equipment prolongs its service life. [0004] In the prior art, the shock absorbing mechanism mostl...

Problems solved by technology

[0004] In the prior art, the shock absorbing mechanism mostly adopts a mechanical method, that is, the spring absorbs the shock. However, when the elastic coefficient of the spring is large, although the strong shock can be buffered, the shock generated by itself is greatly increased, so that the combined shock The shock absorption effect is not good, and when the elastic coefficient of the spring is small, it cannot meet the situation of large vibration. In addition, the spring will fail after repeated expansion and contraction
