Embodiment Construction

[0021] figure 1 A rail vehicle 10 is shown schematically. The rail vehicle 10 has a plurality of cars including a first bogie 12 , a second bogie 14 , a third bogie 16 , and a fourth bogie 18 . Wheel axles 21 , 22 are arranged on the first bogie 12 . Wheel axles 23 , 24 are arranged on the second bogie 14 , wheel axles 25 , 26 are arranged on the bogie 16 and wheel axles 27 , 28 are arranged on the bogie 18 . Pressure-acting brakes, to which brake pressure is supplied via a common control valve, are respectively associated with the wheel axles of the bogies. Thus the first control valve 32 is assigned to the first bogie 12 , the second control valve 34 is assigned to the second bogie 14 , the third control valve 36 is assigned to the third bogie 16 and the fourth control valve 38 is assigned to the fourth bogie shelf. The control valves 32, 34, 36, 38 are connected to main pressure lines which supply control pressure to the control valves 32, 34, 36 and 38. The control v...

Abstract

The invention relates to a control device (60) for a brake system of a rail vehicle (10), the brake system having at least one first brake device (41-48) and a second brake device (41-48; 71, 72, 77, 78), which devices can be actuated by an actuating force during a braking process. The first brake device (41-48) and the second brake device (41-48; 71, 72, 77, 78) are adhesion-type brake devices. The control device (60) is capable of receiving and / or generating a loss of adhesion signal, which identifies insufficient adhesion for the first and / or second brake device (41-48), and is also designed, during a braking process, to actuate the first and / or second brake device (41-48; 71, 72, 77, 78) with an increased actuating force if a loss of adhesion signal is present. The invention also relates to a brake system for a rail vehicle comprising a control device of this type, to a corresponding rail vehicle and to a method for controlling the brake system of a rail vehicle using a control device.

Description

technical field [0001] The invention relates to a control device for a braking system of a rail vehicle, the braking system having at least one first braking device and at least one second braking device, and to a braking system for a rail vehicle . A rail vehicle and a method for controlling a braking system of a rail vehicle. Background technique [0002] Different types of brakes are used to brake rail vehicles. The known adhesion-dependent brakes are usually used as service brakes. This adhesion-dependent brake transmits the braking force through the contact between the wheel and the track. However, this contact has only a limited ability to withstand braking forces. This ability to absorb braking forces via the wheel-rail contact is determined by the adhesion between the wheel and the rail and can be parameterized by the adhesion coefficient. If the steering force applied to brake the wheels exceeds the braking force that can be transferred by the adhesion, the whee...
