Problems solved by technology

This disturbing noise occurs especially in high-power brake equipment made of sintered metal, although it has very good braking performance, due to its tribological performance and low material noise reduction, and manufacturing The joint action of the moving disc is easy to cause the stick-slip effect (Stick-Slip)

Embodiment Construction

[0025] 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.

[0026] 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 at least one variable which represents jerky sliding motion, arising from the braking demand, between the brake disk (4) and the at least one friction 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 a deviation of the measured variable from a predefined value or value range of the variable.

Description

technical field [0001] The invention relates to a braking system for a rail vehicle, the braking system has at least one brake actuator, the brake actuator comprises at least one brake disc and at least one brake lining interacting with the brake disc, for The invention also relates to a method for controlling a braking system of a rail vehicle with respect to generating a braking force in response to a braking request. Background technique [0002] A suitable brake system and a suitable method are known, for example, from DE 10 245 207 C1. In such braking equipment, when braking with a relatively small braking force, for example, when driving into a station with stop braking, a high-frequency sudden braking noise is usually generated, which is harmful to passengers and residents near the station. is particularly disturbing. This disturbing noise occurs especially in high-power brake equipment made of sintered metal, although it has very good braking performance, due to it...
