Patent ID: 7073641

Claim:
A braking system for an electric motor, the braking system comprising: a chassis; and at least one brake supported by the chassis, the brake comprising: at least one brake disk connected via a fluted connection to a shaft driven by the motor; an armature that is movable in translation along an axis of rotation of the shaft; a plurality of armature-guiding spacers, at least one of the spacers having a shoulder and an annular lip projecting beyond the shoulder, wherein the lip is received in a corresponding housing in the chassis and the shoulder comes into abutment against the chassis, so as to enable the chassis to take up torque that is exerted on the brake during braking, and each spacer is screwed into a yoke of the brake; a plurality of springs for urging the armature against the disk; and an electromagnet which, when powered, attracts the armature and moves it away from the disk against the action of the springs.
