Abstract
The utility model discloses a central brake installed at the output end of a motor. The central brake installed at the output end of the motor comprises a drum brake, wherein the drum brake comprises a braking plate, a braking drum, a braking shoe, a braking handle and a braking flexible shaft inhaul cable, wherein the braking handle is connected with the braking shoe through the braking flexible shaft inhaul cable, the drum brake is installed at the output end of the driving motor of an automobile, the braking drum is fixed on an output flange of the driving motor, and the braking plate is installed on an end cover of the motor. The central brake installed at the output end of the motor is small in operating hand power and improves the reliability of braking and the safety performance of the automobile. Due to the fact that the central brake is installed at a quite high position, the probability of immersing of the surface of a friction surface of the brake when wheels wade into water is small, and the phenomenon of water fade is avoided. The central brake can cut off power transmission, and therefore the wheel lock situation is avoided. When the function of the central brake is combined with the electric braking function of the motor, braking energy is recycled in an emergency braking process, heat productivity is small, and the service life of the braking shoe is prolonged.
Description
Technical field
The utility model relates to a kind of centre brake.
Background technology
Traditional Parking Brake is many in the additional manually operated mechanical drive mechanism of rear wheel brake, the effect of braking during standstill and emergency brake makes it to have held concurrently, may produce following consequence like this: owing to be in the additional hand operation mechanism of rear wheel brake, easily cause the brake friction Face Immersion when wheel is paddled, friction coefficient is sharply reduced " water fade " phenomenon takes place; Sideslip whipping when trailing wheel is seized can lose directional balance; The brake shoe brake cheek heating is bigger, and friction disc wear is very fast.
The utility model content
Technical problem to be solved in the utility model provides a kind of centre brake that is contained in motor output end, and it can improve the safety of reliability and the vehicle of braking.
The technical solution of the utility model is: the described centre brake that is contained in motor output end comprises drum brake mechanism, described drum brake mechanism comprises back-plate, brake wheel, brake shoe brake cheek, brake-applying handle and braking flexible axle drag-line, and described brake-applying handle connects brake shoe brake cheek by braking flexible axle drag-line; Described drum brake mechanism is installed in the drive motor mouth, and brake wheel is fixed on the drive motor output flange, and back-plate is installed on the electric motor end cap.
Be fixed on brake wheel on the drive motor output flange along with the motor output flange rotates together.But brake-applying handle opens by braking flexible axle drag-line brake activation hoof.The friction lining outside face of brake shoe brake cheek and the internal surface of column of brake wheel form a pair of friction face opposite each other, when brake shoe brake cheek is stressed when being adjacent to brake wheel, can produce friction moment at brake wheel and realize braking.
The utility model installs to drum brake mechanism on the driving motor for electric automobile output flange and constitutes centre brake, plays braking during standstill and emergency brake, and it is little to handle hand-power, has improved the reliability of braking and the safety of vehicle.The centre brake installation site is than higher, and paddling because of wheel causes the less likely of brake friction Face Immersion, the water fade phenomenon can not occur; The effect that central authorities' braking is played is to cut off transmission of power, the wheel lockup situation can not occur; Be used when realizing emergency braking with the electric braking function of motor and reclaimed braking energy, cal val is few, the longer service life of brake shoe brake cheek.
Description of drawings
Fig. 1 (a) and (b) be the structural representation that the utility model is contained in the centre brake of motor output end;
Fig. 2 is braking flexible axle drag-line scheme drawing of the present utility model.
Wherein: 1. electric motor end cap, 2. back-plate, 3. brake wheel, 4. motor output flange, 5. brake shoe brake cheek, 6. braking flexible axle drag-line.
The specific embodiment
In conjunction with Fig. 1 (a) and (b) and shown in Figure 2, the described centre brake that is contained in motor output end comprises back-plate 2, brake wheel 3, brake shoe brake cheek 5, brake-applying handle and braking flexible axle drag-line 6, and brake-applying handle connects brake shoe brake cheek 5 by braking flexible axle drag-line 6; Described centre brake is installed in the automobile drive electric motor mouth, and brake wheel 3 is fixed on the drive motor output flange 4, and back-plate 2 is installed on the electric motor end cap 1.Described brake wheel 3 is fixed on the drive motor output flange 4 along with motor output flange 4 rotates together, but brake-applying handle opens by braking flexible axle drag-line 6 brake activation hoof 5.The friction lining outside face of brake shoe brake cheek 5 and the internal surface of column of brake wheel 3 form a pair of friction face opposite each other, when brake shoe brake cheek 5 is stressed when being adjacent to brake wheel 3, can produce friction moments at brake wheel 3 and realize braking.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all be included within the protection domain of the present utility model.
