Problems solved by technology

In order to limit the influence of the frictional conditions on the brake force that can be generated or transmitted, small tolerances are predetermined, especially in brake linings, with respect to shape- and dimensional stability, material composition, stiffness, etc., which accordingly entails Comes the higher cost

Embodiment Construction

[0020] exist figure 1 A disc brake 1 for a rail vehicle according to a preferred embodiment of the invention is shown in , as is also known in principle, for example, from DE 10 245 207 C1 and is therefore only briefly described below.

[0021] The disc brake 1 comprises a brake caliper unit 2 as a brake actuator or brake application device, which has a service braking unit and an energy storage braking unit (not shown here). The brake caliper unit 2 comprises a brake disc 4 which cooperates with, for example, two brake linings 6 in a known manner, figure 1 Only one of the two brake linings is visible in the side view of the . The brake caliper unit 2 is preferably actuated pneumatically for generating a braking force F acting in the circumferential direction of the brake disc 4 according to the braking requirements B . Alternatively, it is of course also possible for the brake caliper unit 2 to be actuated with a pressure medium in another way, for example hydraulically or...

Abstract

The invention relates to a brake system (1) of a rail vehicle, having at least one brake actuator (2) comprising at least one brake disk (4) and at least one brake lining (6), which interacts with said brake disk (4), for generating a braking force in response to a braking demand. The invention provides at least one sensor device in order to measure the time profile of at least one variable, such as wheel rotational speed, wheel circumferential acceleration, braking force, braking torque or brake pressure, which represents fluctuations in the friction conditions between the wheel or wheel set assigned to the brake actuator (2) and the rail and / or between the brake disk (4) assigned to the brake actuator (2) and the at least one brake lining (6), and to output a signal dependent on the measured variable to a control device which is designed so as to adapt the braking force generated by the brake actuator (2) as a function of the deviation of the time profile of the measured variable from a predefined or expected time profile of the variable.

Description

technical field [0001] The invention relates to a braking system for a rail vehicle according to the preamble of claim 1, the braking system having at least one brake actuator corresponding to a wheel or wheel pair, the brake actuator comprising at least one brake disc and at least one brake lining cooperating with the brake disc for generating a braking force according to the braking demand, the invention also relates to a device according to the preamble of claim 4 for controlling such Method of braking equipment. Background technique [0002] A braking system of this type or a method of this type is known, for example, from DE 10 245 207 C1. In such braking systems, the frictional conditions between the wheels or wheelset and the rail or between the brake disc and the associated brake lining depend partly significantly on the weather, ambient temperature, state of wear and load distribution fluctuation. Furthermore, the frictional conditions are not fixed depending on ...
