| 摘要 |
The invention relates to an actuating apparatus for a brake device, preferably a disc brake or shoe brake, of a rail vehicle, comprising a cylinder (1) which has a piston (2) guided therein for actuating brake actuators, wherein the piston (2) can be moved by changing the brake pressure in the cylinder (1) on a pressure side (4) of the piston (2), wherein depending on the movement of the piston (2), an air volume (5) delimited by at least the cylinder (1) and piston (2) is changed. In order to reduce the sensitivity of the actuating apparatus with respect to environmental influences and simultaneously increase the service life, according to the invention the air volume (5) is sealed from the environment in order to prevent a pressure equalisation between the air volume (5) and atmospheric pressure, and at least one pressure equalisation means (6) is connected to the air volume (5). |
