Integrated electric drive axle controller shock absorber

Abstract

The invention discloses an integrated electric drive axle controller damping device, which includes a mounting seat, a mounting slider, a shock-absorbing spring structure and at least two damping structures. There is an escape opening, and the installation slider has an opposite installation end and a connecting end. The connection end is movable and installed in the installation cavity along the up and down direction, and the installation end protrudes from the avoidance opening to the outside of the installation cavity. Two shock-absorbing springs between the connection end and the inner wall of the installation cavity, and two at least damping structures are arranged at intervals along the circumference of the installation slider. Among the slots and damping blocks, one of them is set at the connection end, and the other is set on the inner wall of the mounting seat, which reduces the vibration of the electric drive axle controller and protects the components in the electric drive axle controller, which has a good effect .

Description

technical field [0001] The invention relates to the technical field of installation of an automobile electric drive axle controller, in particular to an integrated electric drive axle controller damping device. Background technique [0002] In recent years, new energy vehicles have developed rapidly, and the power system of new energy vehicles is also developing rapidly in the direction of integration and high efficiency. The integrated electric drive axle is the leader in the integration and high efficiency of electric drive systems for new energy vehicles, but While it has significant advantages, its disadvantages are also obvious. The structure of the electric drive axle causes the core components of the electric drive system, the motor and the controller, to be located below the shock absorber of the vehicle, but the controller has circuit boards, control chips, and IGBTs inside. And other precision electronic components, if the running road conditions are bumpy, it is e...

[0002] In recent years, new energy vehicles have developed rapidly, and the power system of new energy vehicles is also developing rapidly in the direction of integration and high efficiency. The integrated electric drive axle is the leader in the integration and high efficiency of electric drive systems for new energy vehicles, but While it has significant advantages, its disadvantages are also obvious. The structure of the electric drive axle causes the core components of the electric drive system, the motor and the controller, to be located below the shock absorber of the vehicle, but the controller has circuit boards, control chips, and IGBTs inside. And other precision electronic components, if the running road conditions are bumpy, it is easy to cause damage to the internal precision electronic components;

[0003] At present, the controller only adopts a simple method of shock absorption, and the shock absorption effect is relatively poor, which needs to be optimized
