BRAKE LINING FOR RAILWAY VEHICLE, DISC BRAKE SYSTEM FOR RAILWAY VEHICLE INCLUDING SAME, AND SINTERED FRICTION MATERIAL TO BE USED FOR BRAKE LINING FOR RAILWAY VEHICLE
There is provided a brake lining for railway vehicle that can reduce brake squeal in braking. A brake lining for railway vehicle is used for a disc brake system of a railway vehicle. This brake lining includes a base plate, a sintered friction material, and a friction material supporting mechanism. The friction material supporting mechanism is disposed between the base plate and the sintered friction material and supports the sintered friction material in such a manner that the sintered friction material can move with respect to the base plate. The sintered friction material has a Young's modulus of 35.0 GPa or more.

VEHICLE BRAKE 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.

Device and method for forecasting wear in brake linings
A device and method for forecasting the brake lining wear, in particular the brake lining of rail vehicles, wherein the lining thicknesses, the sliding speed, the contact pressure, the total braking time, as well as optionally the temperature or the brake power are determined in a parameterization process during test drives with measurements at predefined time intervals, and the wear, the constant, as well as the material parameters are determined therefrom, where during the operating state, the wear rates are determined via the now known values of the material parameters and of the constants, and the wear is determined therefrom and, from the maximum allowable wear values, a remaining total braking time is then determined until the next lining replacement is required.
