Abstract
A braking device for an electric motor includes two brake pads, which are connected to brake disks, which cooperate with a brake rail. The two brake pads are rigidly connected by a connecting element, which is able to experience a certain deflection under the influence of a piezoelectric element, which is used to distance the two brake pads from each other. An assembly, which includes the two brake pads and their connecting element, is fastened on a support by a fastening device, which is elastically deformable along the direction at right angles with respect to the brake rail and to the two brake pads. The elastically deformable fastening device is formed of plates, which are connected on one end to the assembly and on the other end to the support.
Claims16
A braking device for an electric motor, comprising:
- at least two brake pads adapted to cooperate with at least one of (a) a brake rail and (b) a brake disk arranged between the brake pads, the brake pads adapted to press the at least one of (a) the brake rail and (b) the brake disk laterally to brake a movable part of the electric motor;
- a distancing device, the brake pads connected to the distancing device, the distancing device configured to change a clearance between the brake pads to activate and deactivate the braking device;
- a support;
- and
- a fastening device, an assembly of the brake pads and the distancing device fastened on the support by the fastening device;
- wherein the fastening device is elastically deformable relative to the support along at least one direction at a right angle with respect to a longitudinal direction of the at least one of (a) the brake rail and (b) the brake disk.
An electric motor, comprising:
- at least one of (a) a brake rail and (b) a brake disk connected to a movable part of the electric motor;
- and
- a brake device including:
- at least two brake pads, the at least one of (a) the brake rail and (b) the brake disk arranged between the brake pads, the brake pads adapted to cooperate with the at least one of (a) the brake rail and (b) the brake disk, the brake pads adapted to press the at least one of (a) the brake rail and (b) the brake disk laterally to brake the movable part of the electric motor;
- a distancing device, the brake pads connected to the distancing device, the distancing device configured to change a clearance between the brake pads to activate and deactivate the braking device;
- a support;
- and
- a fastening device, an assembly of the brake pads and the distancing device fastened on the support by the fastening device;
- wherein the fastening device is elastically deformable relative to the support along at least one direction at a right angle with respect to a longitudinal direction of the at least one of (a) the brake rail and (b) the brake disk.
A braking device for an electric motor, comprising:
- at least two brake pads for cooperating with at least one of (a) a brake rail and (b) a brake disk arranged between the brake pads, the brake pads pressing the at least one of (a) the brake rail and (b) the brake disk laterally for braking a movable part of the electric motor;
- distancing means, the brake pads connected to the distancing means, the distancing means for changing a clearance between the brake pads for activating and deactivating the braking device;
- a support;
- and
- fastening means, an assembly of the brake pads and the distancing means fastened on the support by the fastening means;
- wherein the fastening means are elastically deformable relative to the support along at least one direction at a right angle with respect to a longitudinal direction of the at least one of (a) the brake rail and (b) the brake disk.
