Abstract

The invention relates to the technical field of new energy automobiles, and discloses an electric drive type new energy automobile brake. According to the electric drive type new energy automobile brake, through the attraction force between the first permanent magnet and the iron core and the magnetic distribution between the first permanent magnet and the second permanent magnet and the iron core after the iron core generates field intensity, electric power in a new energy automobile directly acts on a braking part, conversion is not needed, and therefore the energy utilization rate is high; according to the invention, other power sources are not needed, timely resetting can be realized, the demand degree for the power sources is low, and the first permanent magnet and the second permanent magnet move to drive the components to be linked, so that the precision demand for each cavity structure is low, the effective service life is relatively long, the maintenance difficulty is low, braking is realized through an electromagnetic principle, and the instant braking capability is realized; the braking strength can be controlled only by controlling the magnitude of the electric power, so that the control precision is higher, and the control is more convenient.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an electric drive type new energy vehicle brake. Background technique [0002] At present, most automobile brakes include drum brakes and disc brakes. Among them, the disc brakes have the greatest advantages. When the existing disc brakes are working, a hydraulic pump is required to inject hydraulic oil into the piston of the brake, thereby producing a clamping type. However, in the new energy vehicle, the electric power of its own power source cannot be used directly to achieve braking, and it needs to be converted. Moreover, the disc brake needs to be driven by a hydraulic device, so when it is working, due to the flow rate of the pipeline. Limitation, the braking will be delayed, and when the brake rebounds, the power source needs to be reset, and the power source also comes from the hydraulic pump. In other words, the requirements for the power source are relative...
