Problems solved by technology
[0004] In the prior art, the electromechanical damping mechanism mostly adopts a mechanical method, that is, the pilot spring damps the shock. However, when the elastic coefficient of the pilot spring is large, although the strong vibration can be buffered, the vibration generated by itself is greatly increased, thus As a result, the total vibration is not reduced much, and the shock absorption effect is not good. When the elastic coefficient of the pilot spring is small, it cannot meet the situation of large vibration. In addition, the pilot spring will fail after repeated expansion and contraction.

Embodiment Construction
[0023] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] like figure 1 The illustrated embodiment of the present invention provides an electromechanical damping mechanism, including: two supporting cylinders 20, a variable pump 10, an oil tank 30, an accumulator 40, a pilot control valve 50, a proportional pressure reducing valve 70; 100. Specifically, two support cylinders 20 are arranged between the chassis and the bridge body of the mobile device; the variable pump 10 communicates with the rodless cavity 21 of the support cylinder 20 through a hydraulic pipeline, and the variable pump 10 provides support force for the support cylinder 20; the support cylinder The rod cavity 22 of 20 communicates with the oil tank 30; the rated pressure of the accumulator 40 is lower than the...

The invention discloses an electromechanical shock absorption mechanism. The electromechanical shock absorption mechanism comprises two supporting cylinders, a variable pump, a fuel tank, an energy accumulator, a pilot control valve and a proportional pressure reducing valve. According to the electromechanical shock absorption mechanism, vibration is buffered through flowing of pressure oil, and the two more important things are that the buffer function is achieved through the method that the pressure oil in rodless cavities flows to the energy accumulator; and the pilot control valve is controlled through the proportional pressure reducing valve to be switched between the disconnection position and the connection position so that connection and disconnection between the rodless cavities and the energy accumulator can be controlled. In this way, movable equipment can stably run on the level road surface and can also stably run on the bumped road surface through the method that the pressure oil is made to flow by controlling the pilot control valve for buffering the vibration.
Description
technical field [0001] The invention relates to the technical field of electromechanical integration, in particular to an electromechanical 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 parts, an electromechanical shock absorbing mechanism is installed between the chassis and the tires of the vehicle, and the electromechanical shock absorbing mechanism is used to buffer the above impact. Thereby slowing down the vibration of mobile equipment and prolonging its service life. [0004] In the prio...
