Abstract

The invention discloses a convenient rear brake assembly which is applied to a disc brake for a low-speed four-wheeled electric car. The convenient type rear brake assembly comprises a rear brake shell (23), a rear tong subassembly (25), a rear brake piston (26), a rear brake shoe (27), a parking seat (19) and a parking rocker arm (14), wherein a transmission nut (24) is mounted in the parking seat (19); the transmission nut (24) sleeves a transmission bolt (17); an adjusting screw rod (15) is connected with the rear tong subassembly and mounted in the transmission bolt; the other end of the adjusting screw rod (15) is connected with the parking rocker arm (14). The transmission bolt, the transmission nut, the adjusting screw rod and the other driving parts are arranged in a longitudinal sleeving manner; the convenient type rear brake assembly is simple and compact in structure, small in occupied space, and convenient to assemble, so that the whole volume of the product is small and the weight is light; furthermore, the production cost is lowered.

Description

technical field [0001] The invention relates to a vehicle brake, which belongs to the field of electric vehicle manufacturing, in particular to a rear brake assembly (ie, a brake caliper and a parking device) used for the brake of a low-speed four-wheel electric vehicle. Background technique [0002] Low-speed four-wheel electric vehicles are a new type of vehicle, and their load and maximum speed are lower than those of automobiles, which are comparable to two-wheel electric vehicles. At present, the mainstream of their brakes is basically drum brakes for both front and rear wheels, and the braking effect is not ideal. . Due to the poor heat dissipation performance of the drum brake, a large amount of heat is generated during the braking process, which can easily cause the temperature of the brake pad to rise and the friction coefficient to drop, resulting in thermal decay, reduced braking efficiency, poor braking stability and poor braking stability. At the same time, noi...
