Magneto-rheological hydraulic brake executing device for electric vehicles

The invention relates to a magneto-rheological hydraulic brake executing device for electric vehicles and belongs to the technical field of electric vehicles. The magneto-rheological hydraulic brake executing device comprises a driving shaft, a brake disk, magneto-rheological liquid, a shell, an electromagnetic coil, connecting plates and a support structure from the inside to the outside. The driving shaft and the brake disk are fixedly connected with a spline and transmit torque to wheels. A left shell piece and a right shell piece are integrally connected through bolts, the brake disk is horizontally disposed in the shell, and the magneto-rheological liquid is filled into the shell. The electromagnetic coil takes an iron core as a support, is limited and fixed by bolts distributed on the support and fits with the outer surface of the shell to form a magnetic loop. The support structure comprises a left portion and a right portion, is fixedly connected with a car body, transmits brake force to the vehicle body, supports the electromagnetic coil through bolts and fixes the brake structure by bolts. The magneto-rheological hydraulic brake executing device is simple and compact in structure, accordant with requirements of the vehicles, capable of setting pressure at millisecond magnitude and convenient to adjust and can meet the requirements for brake strength of the vehicles.
