Abstract
A brake device of an electric vehicle mainly comprises a motor 1 comprising a motor shaft 2 and an end cover 4, and an expansion brake composed of a rocker arm 7, a pin 5, a spring 6 and an expansion brake skin 3, wherein the expansion brake skin is arranged in an inner cavity of the end cover of the motor. The utility model discloses combine brake block and driver part, make it directly implement the braking to driver part, can shorten braking time, reduce braking torque.
Description
The utility model relates to a kind of bicycle disc brake, belongs to the vehicle braked control mechanism.
Existing mini-motorcycle or boosted vehicle, its control of braking mainly acts on wheel hub or the wheel shaft, and is irrelevant with power part, both made wheel stressing conditions complexity, again braking produced hysteresis quality.
The purpose of this utility model provides a kind of reasonable in design, directly acts on the bicycle disc brake on the vehicular drive parts.
The utility model is a bicycle disc brake, mainly comprises the motor 1 that contains motor shaft 2 and end cap 4, by rocking arm 7, and pin 5, spring 6, the lock that rises that the brake rubber block 3 that rises constitutes, the brake rubber block 3 that rises places the electric motor end cap inner chamber, and rocking arm is fixed on the motor shaft 2.When needs carry out glancing impact to battery-driven car, by the rocking arm effect, overcome the pulling force of spring 6, the brake rubber block 3 that rises contacts with end cap 4 surfaces, makes the motor stall, and then orders about parking.
The utility model reasonable in design organically combines brake component and drive element, makes it directly drive element to be implemented braking, can shorten braking time, reduces lock torque.Simultaneously, the brake rubber block that will rise places in the electric motor end cap, has shortened the axial length of vehicle axles parts, and is also very favourable to the unit design of battery-driven car.The utility model can be used for the repacking of existing battery-driven car, also is applicable to unit design and installation at motor bike, motorbike, Moped Scooter, Electrical Bicycle.
Accompanying drawing has provided structural representation of the present utility model.
Fig. 1 is a cross section structure cutaway view of the present utility model;
Fig. 2 is an axial arrangement cutaway view of the present utility model.
Below in conjunction with embodiment the utility model is further described:
Fixed electrical machinery axle 2 on the chain stay of battery-driven car, motor shaft 2 has replaced the hind axle of battery-driven car, the end cap 4 of motor 1 has replaced the rear axle left side floral disc of battery-driven car, and the rocking arm 7 of the lock that rises also is fixed on the motor shaft 2, the brake rubber block 3 that rises is corresponding with electric motor end cap 4 surface of internal cavity, but gapped under non-braking mode, the fork of the lock that rises is fixed on the right pipe of chain stay, and links by the brake lever on pull bar and the handle.When the needs glancing impact, with holding tight brake lever, by pull bar, fork, the effect of rocking arm and pin 5 overcomes the pulling force of spring 6, and the brake rubber block spreading that rises is close on electric motor end cap 4 inside faces, reaches the purpose of braking motor.
Claims (1)
1, a kind of bicycle disc brake comprises the motor (1) that contains motor shaft (2) and end cap (4), and it is held to levy and is also to comprise by rocking arm (7), pin (5), and spring (6), the lock that rises that the brake rubber block that rises (3) constitutes, the brake rubber block that rises places the electric motor end cap inner chamber.
