Abstract

The invention relates to a brake cylinder (1) comprising a locking device (10) for mechanical brake force locking, in particular for rail vehicles, and comprising a service brake piston (2) which can be axially moved inside a housing (1), which can be moved by applying a pressure medium thereto, and which is coupled to a piston tube (5), said piston tube (5) being provided with a non-self-locking thread (9) which is engaged with a threaded nut (7) which is rotatably mounted in the housing (1), and the locking device (10) cooperating with toothing (8) of the threaded nut (7). The brake cylinder is designed such that the locking device (10) comprises one or more pawl(s) (11, 12), a control piston (13), an emergency release tappet (14), and a locking element (17) of the emergency release tappet (14).

Description

technical field [0001] The invention relates to a brake cylinder with a locking device for mechanical brake force locking according to the preamble of claim 1 . Background technique [0002] In order to prevent a parked rail vehicle from rolling away under any circumstances, the parking brake must ensure a correspondingly high braking force even without an external energy supply. [0003] If a rail vehicle parked in this way has to be towed, there is usually no compressed air supply available to the vehicle, via which the locking can be released. In this case, the parking brake must be equipped with a corresponding mechanical release (emergency release or auxiliary release), by means of which the parking brake can be released manually, ie without using external energy. The mechanical release is also used to safely disengage the pliers from force when changing brake linings. It is not permissible to change the brake linings while the spring accumulator is released pneumatic...
