Abstract
The utility model discloses an electric vehicle rear axle disc brake device which comprises a disc brake caliper assembly and a disc brake plate integrally formed by a disc brake sheet and a fixing boss. Stepped holes for a rear axle half shaft to be installed is arranged at the centers of the disc brake sheet and the fixing boss. The disc brake caliper assembly is installed on the outer side of the disc brake sheet. Multiple heat radiation hole groups are further annularly distributed on the disc brake sheet. An installing hole is formed in the fixing boss. The electric vehicle rear axle disc brake device adopts an electronic brake caliper as a brake device and can share the same power supply with an electric vehicle, and the suitability is improved. In addition, the electric vehicle rear axle disc brake device is simple in overall structure, large in acting radius, large in braking torque, good in braking effect, high in safety performance, good in heat radiation effect and long in service life and very suitable for the electric vehicle.
Description
Technical field
The utility model relates to a kind of motor rear axle member, is specifically related to a kind of motor rear axle disc brake apparatus.
Background technique
The braking device of vehicle is mainly divided into disc brake and drum is stopped two kinds, but the braking device that electric motor car at present uses is all stopped as main take drum, but drum type braking device action radius is little, braking moment is little, brake drum is frangible, and braking effect and poor safety performance do not meet the brake request of electric motor car, and traditional disc brake apparatus is all using hydraulic pressure as retardation pressure, be equally also not suitable for using in electric motor car.
Summary of the invention
For addressing the above problem, the utility model proposes a kind of power supply and be positioned at the motor rear axle disc brake apparatus in brake power source, it is simple in structure, good braking effect, Safety performance are high, perfect heat-dissipating and long service life.
Motor rear axle disc brake apparatus of the present utility model, comprises disc brake pincers assembly and the disk brake being made into integration by disc brake sheet and fixing lug boss; The center of described disc brake sheet and fixing lug boss is provided with the step hole for rear axle shaft is installed; Described disc brake pincers assembly is arranged on the outside of disc brake sheet; On described disc brake sheet, also annular is evenly equipped with multiple tracks radiation hole group; In described fixing lug boss, be provided with mounting hole.
Further, described disc brake pincers assembly also comprises electronics clamp, reduction gear and motor.
Further, described radiation hole group is made up of multiple radiation hole arc shootings not of uniform size, and arranges outward from interior successively from small to large.
Further, described mounting hole is provided with 5, and annular is distributed in fixing lug boss front side.
Compared with prior art, it has following beneficial effect to the utility model:
Motor rear axle disc brake apparatus of the present utility model has adopted electronic type brake calipers as braking device, can with the same power supply of electric motor car, improved suitability; And overall structure is simple, the large braking moment of action radius is large, good braking effect, Safety performance are high, good heat dissipation effect and long service life, is applicable to very much electric motor car and uses.
