ABSTRACT:
An automatic brake for vehicle winch that is automatically applied when the applied torque of the drive motor ceases and automatically released upon application of motor torque. The brake features brake pad segments that move radially outward against the interior of the drum to affect braking and retract radially inward to affect releasing of the brake. The pads have tapered ends that mate with opposed frusto-conical shoes. The brake utilizes rotation of a cam rotatable with respect to a cam follower in one direction to force one shoe toward the other to force the pads radially outward to engage the interior surface of the drum. Rotation of the cam with respect to the cam follower in the opposite direction releases the braking action. A wave spring is incorporated to eliminate chatter as the brake is applied and released. The configuration of the brake components provides a conductive path for the dissipation of heat generated by the braking action.
