Disk braking system for electric automobile axle assembly

Abstract

The invention relates to a disk braking system for an electric automobile axle assembly. The disk braking system for the electric automobile axle assembly comprises a half shaft (1), wherein a hub (8) is fixedly connected to the outer side of the half shaft. The disk braking system for the electric automobile axle assembly is characterized in that a brake disc (7) also sleeves the half shaft and is fixedly connected onto the hub; a brake caliper (2) in brake fit with the brake disc is connected onto the brake disc (7), and comprises a caliper body (3); brake plates (5) are respectively connected to two sides of the caliper body (3) in a sliding fit way, and are correspondingly arranged on two sides of the brake disc (7); a friction plate (6) in brake fit with the brake disc (7) is connected to the inner side face of each brake plate (5) in a fit way; a pressure wall (4) in pressure fit with one brake plate (5) is also connected to the outer side of the brake plate (5). The invention has the advantages that the device is simpler in structure, easy to maintain and convenient for replacing the friction plate, and has better heat stability, water stability and brake stability.

Description

technical field [0001] The invention relates to a vehicle brake device, in particular to a disc brake device used in an electric vehicle axle assembly. Background technique [0002] With the progress of society, the number of automobiles is increasing, and automobile exhaust has become one of the main sources of environmental pollution. As people's awareness of environmental protection continues to increase, and the inherent natural resources on the earth continue to decrease, it is necessary to look for alternatives to automobile fuels. Products have become an urgent problem to be solved. Therefore, the development of green and environmentally friendly electric vehicles is already the development direction of future automobiles, and it will occupy a place in the field of new energy vehicles in the future. The matching electric vehicle bridge is also urgently needed to be developed and developed. [0003] At present, the braking device used for electric vehicles is mainly th...
