Problems solved by technology

However, due to the pneumatic brake valve and the reversing valve, on the one hand a more complex structure results
On the other hand, actuating the redundant pneumatic parking brake circuit by means of the foot brake pedal of the service brake system in the event of failure of the preceding electric parking brake circuit is a less intuitive process for the driver

Embodiment Construction

[0027] figure 1 A schematic circuit diagram of a preferred embodiment of the electropneumatic parking brake device 100 according to the invention is shown. The electropneumatic parking brake system 100 is a parking brake component of an electropneumatic brake system of a towing vehicle-trailer combination and is arranged on the towing vehicle. In addition to the parking brake system 100 , an electropneumatic service brake system not shown here, such as the EBS, is a service brake component of the electropneumatic brake system.

[0028] The electropneumatic parking brake control device 1 of the parking brake device 100 is preferably embodied here as a parking brake module or subassembly having a container connection 2 secured by a non-return valve 4 . From this container connection 2 , the container line 6 extends on the one hand to a solenoid valve arrangement 8 with a 2 / 2-way valve 10 as an inlet valve and a 2 / 2-way valve 12 as an outlet valve. The first 2 / 2-way directional...
