Abstract

The invention discloses a transmission and braking integrated device for a vehicle. The transmission and braking integrated device comprises a wheel rim, a brake, a speed reducer and a motor. The brake comprises a vehicle end cover, a traveling cylinder body, a traveling piston, a cylindrical intermediate body, a braking friction pair assembly, a parking cylinder body, a parking piston, a parking end cover and a parking spring. The traveling cylinder body is sleeved with the traveling piston in a movable fit manner. An annular gap exists between the traveling piston and the traveling cylinder body, wherein the annular gap is a traveling braking oil cavity. The parking piston is arranged in the parking cylinder body in a movable fit manner. An annular gap exists between the parking cylinder body and the parking piston, wherein the annular gap is a parking braking oil cavity. The traveling piston and the parking piston can abut against the friction pair assembly from the two sides correspondingly. The parking piston is provided with the parking spring abutting against the parking end cover. By means of the transmission and braking integrated device for the vehicle, the motor, the brake and the speed reducer are integrated, the brake is arranged in the wheel rim, the speed reducer is arranged in a cavity of the brake, the structure is compact, the size is small, the space of a vehicle frame is greatly saved, and the transmission and braking integrated device is very suitable for flexible configuration with various vehicles narrow in structure space.

Description

technical field [0001] The invention relates to a vehicle transmission and braking integrated device. Background technique [0002] Separated motors, brakes, and reducers are used on the axles of vehicles. Not only is the structure complex, but the motors, brakes, and reducers respectively occupy the space of the vehicle chassis and are relatively large. For example, the low-floor design of new energy buses, the structure The space is narrow, and the motor, brake, and reducer cannot be given a large installation space. [0003] A utility model patent with the Chinese application number 201520191083.7 discloses a vehicle transmission and brake integrated device, which includes a brake and a reducer located in the rim; one side of the rim has a holed end disc that is firmly connected to the output flange; the brake The end adjacent to the end disk contains friction plates distributed at intervals, and a brake disc is installed between adjacent friction plates, and an oil cyli...
