Abstract
The present disclosure relates to an electric brake system for an electric vehicle, which is more economical by simplifying a configuration of an electric vehicle that includes a main service brake and an electromagnetic brake, the electric brake system including an inductor, in a spherical shape, formed so that a drive axle penetrates through a center portion of the inductor; a plurality of springs inserted into holes defined in the inductor; an armature, in a disk shape, provided to contact the spring; and a friction disk mounted on a side of a motor, where a braking force is generated by operating the friction disk toward the armature.
Claims6
An electric brake system for an electric vehicle, comprising:
- an inductor, formed so that a drive axle penetrates through a center portion of the inductor;
- a plurality of springs inserted into holes defined in the inductor;
- an armature, in a disk shape, provided to contact the spring and operated by the inductor to generate a first braking force;
- a friction disk mounted on a side of a motor;
- and
- a brake member disposed between the motor and the friction disk,
- wherein when the first braking force due to the operation of the armature is released, a second braking force is generated by operating the friction disk toward the armature and
- wherein the brake member operates the friction disk to provide the second braking force.
