Abstract
A furniture drive includes an electric drive motor and a brake device. The drive motor has an output shaft which projects beyond a motor housing and the brake device has at least one brake element and one force accumulator. The force accumulator permanently loads a friction surface of the at least one brake element with a brake force. The force accumulator and the brake element are configured in one piece. Coefficients of static and sliding friction between the friction surface of the brake element and the output shaft differ by a factor of at least 1.3. An EMF brake is provided for the drive motor.
Claims17
A furniture drive, comprising:
- an electric drive motor having an output shaft projecting beyond a motor housing;
- and
- a braking device comprising at least one braking element and a force accumulator, wherein the force accumulator permanently applies a braking force to a friction surface of the at least one braking element, and wherein the force accumulator and the braking element are integrally formed,
- wherein static and sliding friction coefficients between the friction surface of the braking element and the output shaft differ by a factor of at least 1.3, and wherein the drive motor is activatable as an EMF brake.
