Problems solved by technology

[0010] Said method in the disclosed form has the following disadvantages: the model on which it is based does not allow any heat conduction through the brake disc, and the cooling is not calculated as a function of speed, whereby the results of the calculated temperature rise and temperature drop may contain Inaccurate
There is no prediction of the critical temperature that may occur in the future

Embodiment Construction

[0033] exist figure 1 , a schematically illustrated cross-section of a friction braking system of a rail vehicle showing a pneumatic disc brake.

[0034] The pneumatic disc brake comprises a first friction element 1 embodied as a brake disc mounted on a wheel set axle (not shown) of a rail vehicle, and a brake caliper. The brake caliper has a second friction element 2 comprising two brake pads. The brake caliper further comprises a brake cylinder 4 with a compressed air connection 6 , a piston 5 and a connecting rod 3 .

[0035] The piston 5 actuates the connecting rod 3 , whereby the brake pad arranged on the connecting rod 3 , ie the second friction element 2 , is pressed against the brake disc, ie the first friction element 1 . Compressed air from the rail vehicle's compressed air system (not shown) is applied to the piston 5 via a compressed air connection 6 to actuate the connecting rod 3 .

[0036] The compressed air system has components for open-loop control and clo...

Abstract

The invention relates to a method for influencing the kinematic behavior of a vehicle, in particular a rail vehicle with at least one friction brake system, wherein a brake effect is generated by pressing at least one first friction element (1) and a second friction element (2) against each other. In order to achieve advantageous method conditions, at least temperatures (TS) at least of the firstfriction element (1) are calculated at least from information on a speed, a brake pressure (p), and an external temperature (TU) of the vehicle and on absolute times (t), and a heat conduction throughthe at least first friction element (1) and a speed-dependent cooling process of the at least one first friction element (1) are taken into consideration during the calculation. The kinematic behavior of the vehicle is influenced on the basis of said calculation. Advantageously, expensively fitting the friction brake system with sensors for measuring friction element temperatures can be omitted,and the thermal state of the friction brake system can still be estimated with a high degree of precision.

Description

technical field [0001] The invention relates to a method for influencing the kinematic behavior of a vehicle, in particular a rail vehicle having at least one friction braking system, wherein the braking effect is produced by pressing at least a first friction element and a second friction element against each other . Background technique [0002] Vehicles are often equipped with friction braking systems, in which the braking effect on the vehicle is triggered by pressing the friction elements against each other, ie the kinetic energy of the vehicle is converted into heat. Known embodiment variants of friction braking systems include, for example: pneumatic disc brakes. Pneumatic disc brakes include, for example, a brake disc mounted on a wheel set, and a brake caliper including a brake cylinder, a connecting rod, and brake pads. The brake cylinder has a piston by means of which the brake rod is actuated and the brake pad is pressed against the brake disc. The brake cylin...
