Abstract
The invention relates to a brake actuator, especially for a rail vehicle brake, comprising an accumulation brake unit having an energy accumulator for storing and supplying energy for applying the brake, preferably in the event of safety braking and/or park braking, and a locking device for locking and unlocking the energy accumulator. After the release of the locking device, an inertia weight from part of the energy released from the energy accumulator can be subjected to a rotational movement for damping purposes.
Claims13
Brake actuator for a rail vehicle brake, the actuator comprising:
- an accumulator-type brake unit with an energy accumulator for storing and supplying energy for applying the brake, in the event of a safety and/or parking braking, and having a locking device for locking and unlocking the energy accumulator;
- after the release of the locking device, an inertia weight can be caused to carry out a rotating movement for damping purposes by a portion of the energy released from the energy accumulator;
- and
- the inertia weight having at least one separate inertia element used only for generating mass of the inertia weight during the applying of the brake and not being used during release of the brake.

- the inertia weight having at least one separate inertia element used only for generating mass of the inertia weight;
- and
- wherein the inertia weight is releasably coupled with the energy accumulator by a slipping clutch, which is designed such that, after a braking position has been reached, the inertia weight is uncoupled from the energy accumulator.
