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

Vehicle braking system

The invention concerns a rail vehicle braking system comprising a service brake having a movable piston () which with a body () of the system delimits a service brake chamber () supplied by a first source, a piston rod () disposed in that chamber and fastened to a second side () of the piston turned towards that chamber, and a parking brake () disposed in said body and comprising a blocking device () disposed in that chamber and movable to act on said rod, and a movable actuating device () which is configured to be electrically actuated; said blocking and actuating devices being configured to immobilize/unblock said rod so as to block/unblock said piston in a position.

Rail vehicle braking system and braking method for a rail vehicle comprising such a system

A rail vehicle braking system includes a service brake having a movable piston () which with a body () of the system delimits a service brake chamber () supplied by a first source, a piston rod () disposed in that chamber and fastened to a second side () of the piston turned towards that chamber, and a parking brake () disposed in the body and including a blocking device () disposed in that chamber and movable to act on the rod, and a movable actuating device () which with the body delimits a parking brake pressure chamber () supplied by a second source; the blocking and actuating devices being configured to immobilize/unblock the rod so as to block/unblock the piston in a position.
