Abstract
A machine tool braking apparatus, in particular a hand-held machine tool braking apparatus, of a portable machine tool, includes at least one mechanical braking unit that has at least one movably mounted braking element and includes at least one output unit that has at least one output element. The braking unit includes at least one actuating element that is intended to move the braking element, at least in one operating state, at least substantially perpendicular to an axis of rotation of the output element.
Claims18
A power-tool braking device of a portable power tool, comprising:
- a housing;
- a drive unit supported by the housing;
- at least one output unit including at least one output element configured to be rotationally driven relative to the housing by the drive unit about a rotation axis;
- at least one mechanical braking unit including at least one movably mounted braking element configured to move to a release position that enables rotation of the output element and to move to a braking position for braking rotation of the output element
- wherein the braking unit has at least one actuating element configured (i) to engage the at least one braking element to secure the at least one braking element in the release position in response to the drive unit rotationally driving the at least one output element, and (ii) to release the at least one braking element in response to the drive unit ceasing to rotationally drive the at least one output element, such that the at least one braking element is movable to the braking position.
A power-tool braking device of a portable power tool, comprising:
- an output unit including an output element, the output element configured to be driven rotationally by a drive unit of the power tool, such that the output element defines a rotation axis;
- at least one movably mounted braking element that is rotatable about the rotation axis relative to the output unit and that is configured to brake rotation of the output element, the at least one braking element configured, at least in one operating state, to move at least substantially perpendicularly in relation to the rotation axis;
- and
- a mounting plate connected to the output element in a rotationally fixed manner and including at least one actuating element, when the output element is driven rotationally by the drive unit, the at least one actuating element moves the at least one braking element perpendicularly toward the rotation axis to prevent the at least one braking element from braking the rotation of the output unit.
