Brake cylinder comprising a locking device for mechanical brake force locking

A brake cylinder comprising:

• a locking device for mechanical brake force locking;
• and
• a service brake piston which can be axially moved inside a housing by applying a pressure medium thereto;
• and
• a piston tube coupled to the service brake piston and provided with a non-self-locking thread engaged with a threaded nut which is rotatably mounted in the housing, wherein the locking device cooperates with a toothing of the threaded nut,
• wherein the locking device comprises one or more pawls, a control piston, an emergency release tappet and a locking element for the emergency release tappet,
• wherein the control piston and the emergency release tappet are arranged parallel to one another and proximately adjacent to one another, and
• wherein a control axis of the control piston and an emergency release axis of the emergency release tappet run parallel to one another and at right angles to a piston axis of the brake cylinder.
