Abstract
A brake for drive motors wherein a brake disk is adapted to be pressed against a stationary brake lining which is provided with a bead-like rim and which is held elastically both radially and axially via a molded rubber member having a profile which bears a mating relationship to the bead-like rim, thereby permitting the brake lining to be held by the member detentably in the manner of a snap connection. The brake is further provided with a brake disk ring which is firmly connected to the molded rubber member and which is adapted to be connected to a stationary member.
Claims9
In a brake for use with a drive motor, the brake comprising:
- a brake lining;
- a brake disk adpated to be spring-lifted electromagnetically by an axial displacement of the rotor of the motor against the force of a spring when the motor winding is energized and to come into contact by the force of the spring with said brake lining when the motor winding is deenergized;
- said brake lining and brake disk having mutual contact surfaces arranged in the manner of a conical brake at an oblique angle to the rotor displacement and the action line of the spring force;
- means adapted to connect at least resiliently in the radial direction said brake lining to a stationary member including an elastic intermediate member and a brake disk ring;
- the improvement comprising:
- said brake lining having a formed-on bead-like rim;
- said intermediate member being formed as a molded rubber member having a profile which bears a mating relationship to said rim;
- said brake lining being held via said rim in said rubber member detentably and elastically in the radial and axial direction in the manner of a snap connection;
- and said rubber member being connected firmly to said brake disk ring.
