Damping device for new energy vehicle

Abstract

The invention discloses a damping device for a new energy vehicle. The damping device comprises a piston cylinder, a supporting plate, a piston rod, a first spring, a pressing mechanism, a second spring, transverse damping mechanisms, a connecting spring and hydraulic holes, wherein the supporting plate is arranged above the piston cylinder; the bottom of the supporting plate is fixedly connectedwith one end of the piston rod; the other end of the piston rod extends into the piston cylinder, and is fixedly connected with the pressing mechanism; a first spring and a second spring sleeve the piston rod; one end of the first spring is fixedly arranged on the bottom of the supporting plate; the other end of the first spring is fixedly arranged on the top of the piston cylinder; the second spring is positioned in the piston cylinder; one end of the second spring is fixedly connected with the top end in the piston cylinder; the other end of the second spring is fixedly connected with the pressing mechanism; the transverse damping mechanisms are symmetrically arranged at the two sides of the piston cylinder; and the hydraulic holes are symmetrically formed in the two sides of the pistoncylinder. The damping device for the new energy vehicle can transversely transmit longitudinal vibration, can quickly weaken vibration, is adjustable in damping force, and is long in service life.

Description

Technical field [0001] The invention relates to the technical field of shock absorption for new energy vehicles, in particular to a shock absorption device for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source (or the use of conventional vehicle fuels, the use of new on-board power devices), the integration of advanced technologies in vehicle power control and driving, and the formation of advanced technical principles and For cars with new technologies and new structures, car shock absorbers are an indispensable device in car use, which can provide passengers with a more comfortable riding experience and improve the safety of car driving. [0003] The existing new energy vehicle shock absorber is fixedly connected to the axle and the body. The reduction of vehicle vibration can only reduce the vibration by weakening the reciprocating frequency of the longitudinal spring. The shock absorption ...

AI Technical Summary

Problems solved by technology

[0003] The existing new energy vehicle shock absorber is fixedly connected to the two parts of the axle and the body. The reduction of the vibration of the car can only be reduced by weakening the frequency of the reciprocating motion of the longitudinal spring. The shock absorption effect is poor and the strength of the shock absorption cannot be adjusted. , and the service life is short, for this reason, we propose a shock absorber for new energy vehicles
