Abstract

The utility model provides a brake motor, including motor casing motor casing installs the inboard motor stator through the rotatable motor shaft that installs of bearing on motor casing's the axial direction line the motor shaft overcoat is equipped with electric motor rotor, motor shaft's tail end stretches out the motor casing fixedly connected with brake drum, with install the support on the relative motor casing of brake drum install shoe brake on the support, shoe brake can follow motor shaft's radial direction reciprocating motion. The utility model has the beneficial effect of simple structure, compact and have brake function, especially be fit for the pure electric vehicles motor of motor direct drive.

Description

A kind of braking motor

Technical field

The utility model belongs to technical field of motors, especially relates to a kind of braking motor.

Background technology

In existing technology, drive-motor is the core component of electromobile, and the technical scheme of electric-machine directly-driven taked by electromobile more, eliminates wheel box.

But the problem that cancellation wheel box brings is without park position, it is necessary to additionally increase parking brake drum simultaneously. There is transmission system layout not compact, take and the problems such as space is bigger are installed.

Practical novel content

For solving the problems of the technologies described above, the utility model provides simple, the compact braking motor with braking function of a kind of structure, is especially applicable to the pure electric automobile motor of motor direct-drive.

The technical solution of the utility model is: a kind of braking motor, described motor comprises electric machine casing, motor stator is installed inside described electric machine casing, the axial centre line of described electric machine casing is provided with motor rotating shaft by bearing is rotating, it is set with motor rotor outside described motor rotating shaft, the tail end of described motor rotating shaft stretches out electric machine casing and is fixedly connected with brake drum, the electric machine casing relative with described brake drum is provided with support, being provided with brake shoe on the bracket, described brake shoe can along the radial direction to-and-fro movement of motor rotating shaft.

Further, described brake shoe can actuate structure, its outside surface and brake drum internal surface contact friction after described brake shoe opens.

Further, after described brake shoe shrinks, the gap between brake shoe and brake drum is 5mm-10mm.

Further, being also provided with bolt on outside described brake drum, described bolt is for installing transmission shaft.

The advantage that the utility model has and positively effect be: owing to adopting technique scheme, its outside surface and brake drum internal surface contact friction after control brake shoe opens, frictional force makes brake drum be in braking mode, cannot rotate freely, vehicle is in braking mode, together with brake structure is combined in by this motor with electric motors function, compact in design, takies and installs the advantages such as space is less.

Embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated.

Shown in structural representation as of the present utility model in Fig. 1-Fig. 2, a kind of braking motor of the utility model, described motor comprises electric machine casing 1, inside described electric machine casing 1, motor stator 2 is installed, the axial centre line of described electric machine casing 1 is provided with motor rotating shaft 4 by bearing 3 is rotating, it is set with motor rotor 5 outside described motor rotating shaft 4, the tail end of described motor rotating shaft 4 stretches out electric machine casing 1 and is fixedly connected with brake drum 6, the electric machine casing 1 relative with described brake drum 6 is provided with support 7, described support 7 is provided with brake shoe 8, described brake shoe 8 can along the radial direction to-and-fro movement of motor rotating shaft 4.

Described brake shoe 8 can actuate structure, its outside surface and brake drum 6 internal surface contact friction after described brake shoe 8 opens. After described brake shoe 8 shrinks, the gap between brake shoe 8 and brake drum 6 is 5mm-10mm.

Also being provided with bolt 9 on outside described brake drum 6, described bolt 9 is for installing transmission shaft.

The working process of this example: in use, during electronic start-up and operation, motor rotor 5 and brake drum 6 together rotate braking motor of the present utility model with motor rotating shaft 4, such as Fig. 1, when brake shoe 8 is in contraction schedule, brake drum 6 is in free state, it is possible to rotate freely. After starting motor brake, such as Fig. 2, control for brake device (not shown in FIG.) control brake shoe 8 opens, brake shoe 8 opens its outside surface rear and brake drum 6 internal surface contact friction, frictional force makes brake drum 6 be in braking mode, cannot rotating freely, vehicle is in braking mode. Together with brake structure is combined in by this motor with electric motors function, compact in design, takies and installs the advantages such as space is less.

When gap between brake shoe 8 and brake drum 6 is 5mm-10mm, when starting brake, brake shoe 8 can better limit brake drum 6 and rotate.

Above an embodiment of the present utility model is described in detail, but described content is only better embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model. All equalizations done according to the utility model application range change and improvement etc., all should still belong within patent covering scope of the present utility model.
