Disclosed is a brake system for a railway vehicle, including linings each having at least one positioning member for mechanically fastening the linings in a predetermined position on the system with respect to a disc of the vehicle and a bearing face for tightly gripping the disc under the action of an actuator of the system, and at least one return member for separating the linings from the disc in order to release it when the linings are freed from the action of the actuator; each lining has at least one fastening member formed on an edge, the return member has two opposite end lugs connected to one another by an elastic portion and each mechanically fastened with a the fastening member, and the system is configured such that the fastening members and the end lugs are situated at a distance from the at least one positioning member.

A parking brake valve device for controlling a storage spring parking brake in an electropneumatic brake system includes a compressed air input configured to be connected to a compressed air supply, a parking brake output configured to control a storage spring parking brake, and a trailer-control control output configured to control a trailer control valve (TCV) for a trailer brake system. The parking brake valve device further includes a relay valve pilot control region and a relay valve, a TCV pilot control region configured to control the trailer-control control output, an inlet valve configured to be controlled with a first electrical control signal for supplying air to the TCV pilot control region and the relay valve pilot control region, and a connecting valve configured to be controlled by a second control signal to connect and disconnect the TCV pilot control region and the relay valve pilot control region.

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

The trailer emergency air brake supply line coupler is movable between a control position, where air pressure in the supply line causes the trailer emergency air brakes to release so the trailer can be moved, and a park position where the trailer emergency air brake system is vented to automatically engage the trailer emergency air brakes. The lock includes a metal frame attached to the trailer proximate the trailer coupler. First and second spaced side walls extend from the rear wall of the frame on opposite sides of the trailer coupler. A retractable pin extends between the side walls and intersects the path of movement of the supply line coupler preventing movement of the supply line coupler between its control position and its park position. A lock cylinder, padlock or other mechanism retains the pin on the frame.

A parking brake apparatus is provided for a power unit having air brake parking components and to which a towed unit having air brake parking components can be connected. The parking brake apparatus comprises a controller arranged to monitor a pressure signal indicative of a delivery air pressure applied to the air brake parking components of the towed unit when the towed unit is connected to the power unit. The controller is also arranged to provide a status signal indicative of whether or not a towed unit is connected to the power unit based upon the pressure signal. The controller further enables the status signal to be processed to control application or release of any combination of air brake parking components of the power unit and the towed unit to park or unpark the power unit as well as the towed unit, if connected to the power unit.

An electronically controlled pneumatic brake system (2) for a vehicle 100, with a supply coupling head (24), a control coupling head (26), and an electronically controlled trailer control module (28) includes a first supply port (28.1), a trailer supply connection (28.2) for providing a trailer supply pressure (pT) to the supply coupling head (24), a trailer control connection (28.3) for providing a trailer control pressure (pB) to the control coupling head (26), an electro-pneumatic trailer control valve arrangement (40) for providing the trailer control pressure (pB), and a tractor protection valve electronic control unit (42). The electro-pneumatic trailer control valve arrangement (40) is configured to only supply a trailer control pressure (pB) to the trailer control connection (28.3) when compressed air is supplied to the trailer supply connection (28.2).
