Electric car damping device

Abstract

The invention discloses an electric car damping device. The electric car damping device comprises a support, a first damper is fixedly connected to the upper surface of the support, a first spring and a second spring are arranged in the first damper, a sliding block is arranged between the bottom of the first spring and the top of the second spring, a limiting block is fixedly connected to the top of the first damper, a fixed rod is fixedly connected to the middle of the limiting block, and the bottom of the fixed rod penetrates the first spring to be fixedly connected with the sliding block; and a dead bolt is arranged on the top of the fixed rod, second dampers are fixedly connected to the two ends of the bottom of the support through flanges, and each second damper is internally provided with a third spring and a fourth spring. The electric car damping device enables pressure to be shared, the pressure is decreased progressively in a stage-by-stage manner, the damping effect is better, during use, the device is more comfortable, stress of a single spring is small, generation of mechanical fatigue can be relieved, the service life of the springs is prolonged, and the damping device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle shock absorber. Background technique [0002] The shock absorber of the electric vehicle is used to alleviate the impact brought by the road surface and quickly absorb the vibration caused by bumps. Generally, electric vehicles use a single spring for shock absorption. Although the structure is simple and the cost is low, the shock absorption effect Not good, and the service life of the spring is not high. Although some hydraulic damping devices are used in combination with spring damping devices, although the damping effect is good, the structure is complicated and the cost is high. Contents of the invention [0003] The object of the present invention is to provide a shock absorbing device for an electric vehicle to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present ...
