The invention relates to a control mechanism () configured to equip a rail system and including a casing () from which a control rod () projects, configured to be mechanically and securely connected to a control cable () actuatable at a distance from or in proximity to the casing, a plate () mechanically connected to the casing and from which the control rod projects, and a locking/unlocking device () positioned in a recess () provided in the plate and having a stable position, the control mechanism being configured so that, when the control cable is mechanically connected to the control rod, the locking/unlocking device is elastically moved away from its stable position to allow the partial introduction of the control cable in the plate as far as a position in which the control cable is mechanically and securely connected to the control rod.

Control mechanism for a rail system, rail system provided with such a mechanism and rail vehicle provided with such a system

A vehicle braking system includes brakes, a body, a braking linkage, a service brake comprising a braking piston movable relative to the body to act on the braking linkage and delimiting a service brake pressure chamber to place the braking piston in a service braking position. A parking brake acts on the braking piston and has a working configuration and a resting configuration. The parking brake includes a blocking device movable relative to the body to act on the braking piston and having a first position and a second position in which the blocking device is configured to immobilize the braking piston in a service braking position. A control device is movable relative to the body and has a locking position to hold the blocking device in the second position. A service brake indicator device receives information representing supply and/or venting of the service brake pressure chamber.

Vehicle braking system comprising a service brake indicator device and vehicle provided with such a system

A braking system for a vehicle includes an indicator device provided to reliably indicate a state of a parking brake of the system, while being simple, convenient, and economical. The system includes a body that delimits a service brake pressure chamber and/or a parking brake pressure chamber, a parking brake movable relative to the body, an unlocking part for unlocking the parking brake connected to the parking brake pressure chamber and accessible from outside the body, and a parking brake indicator device. The indicator device is configured to receive a position of the unlocking part via a state pipe and an indicator of supply and/or the venting of the service brake pressure chamber and/or of the parking brake pressure chamber. This information is processed in to detect and indicate an engaged state or a disengaged state of the parking brake.

Vehicle braking system comprising a parking brake indicator device and vehicle provided with such a braking system

The invention relates to a railway braking system for a rail vehicle. The system includes a brake rigging, a service and/or parking brake designed to act on at least one braking member of the vehicle via the brake rigging (which is provided with at least one device having at least one lining support and at least one lining that is mechanically attached to the at least one lining support), and at least one force transmission link. The force transmission link has a first end mechanically attached to a support of the vehicle and an opposite second end mechanically attached to the at least one lining support. The at least one lining support comprises a fastening leg that includes a housing and a mounting member accommodated in the housing, and the second end of the at least one force transmission link is rotatably mounted in the mounting member.

Braking system comprising brake rigging, and vehicle equipped with such a braking system

Disclosed is a brake system for a railroad vehicle, including a parking brake provided with a piston and having a first configuration in which the piston is in a working position in which it acts on a lining support and applies a predetermined force to a brake disc; a second configuration in which the piston is in a rest position in which it does not act on the support and does not apply any force to the disc; and a third configuration in which, when the vehicle is not at a standstill and the ambient temperature in the environment of the disc is greater than a threshold value, it forces the piston to move towards a trip position different from its working and rest positions, in order to limit or cancel the force applied to the disc.

Vehicle brake system

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.

Railway brake system for a railway vehicle

Vehicle braking system

Disclosed is a railway braking system including a first pneumatic distribution device formed by a first distributor provided with a single inlet opening connected to a source for supplying pneumatic pressure mediums and with a single outlet opening connected to a parking brake chamber in order to optionally supply a parking brake with a second pneumatic pressure medium so as to place the brake in either of inoperative and operative configurations, and a second pneumatic distribution device formed by a second distributor provided with a single inlet opening connected to the supply source and with a single outlet opening connected to a service pressure chamber in order to supply a service brake with a third pneumatic pressure medium of which the pressure value is predetermined, so as to apply a predetermined braking force when the parking brake is in the operative configuration thereof.

Vehicle braking system and braking method

Disclosed is a rail braking system including a detection and storage device designed to receive first information representing the position of a device for locking a service brake piston, to receive second information representing the supply of a service brake pressure chamber with a pneumatic pressure agent, to deduce information representing the application of a parking brake from the first and second information, and to store the deduced information; as a result of which the information representing the application of the parking brake is kept even if the service brake pressure chamber is no longer supplied with the pneumatic pressure agent.
