Abstract: 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.

Abstract: 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.

Abstract: The cylinder of the combined service and spring brake comprises a service brake piston rod capable of being connected to a brake linkage by means of a clearance adjuster. It combines the releasing pistons (26, 50) of the spring brake and service brake cylinder (2) with its piston (11) and its piston rod (12) provided with a clearance adjuster (16), and at least a dividing attachment rotating between the spring piston (26) and the ring-shaped base (37), such as a spindle (55) simultaneously passing through an axial bore (56) provided in the ring-shaped base (37) and a conjugated blind bore (57) provided in the spring piston (26). The invention is applicable to combined spring cylinders using the service brake clearance adjuster.
