Brake valve arrangement
View Patent ↗The invention concerns a brake valve arrangement of a vehicle having a trailer coupling and at least one controllable hydraulic consumer, with a brake valve ( 27 ). It is endeavored to provide a similar embodiment of a vehicle with such a brake valve arrangement. For this purpose, the brake valve ( 27 ) is combined with at least one control valve ( 11, 12 ) controlling the hydraulic consumer into forming a valve block ( 10 ) having several valve modules.
1. A brake valve arrangement of a vehicle having a trailer coupling and at least one controllable hydraulic consumer, the brake valve arrangement comprising a valve block having at least two valve modules, wherein at least one valve module controls the at least one controllable hydraulic consumer and at least one other valve module controls a wheel brake cylinder.
2. The brake valve arrangement according to claim 1 , wherein the at least one other valve module controlling the wheel brake cylinder is a brake valve.
3. The brake valve arrangement according to claim 2 , wherein the brake valve is controlled by an electrical signal.
4. The brake valve arrangement according to claim 3 , wherein the electrical signal can be generated by a pressure sensor, which is coupled with a hydraulic brake system of the vehicle.
5. The brake valve arrangement according to claim 4 , wherein a trailer brake pressure sensor is located at an outlet (A) of the brake valve.
6. The brake valve arrangement according to claim 3 , wherein the electrical signal is generated by an advance working control device.
7. The brake valve arrangement according to claim 3 , wherein the electrical signal is generated by an overrunning sensor.
8. The brake valve arrangement according to claim 3 , wherein the electrical signal is changed by an auxiliary device.
9. The brake valve arrangement according to claim 8 , wherein the auxiliary device has at least one of the following elements:
a manual setting device;
a trailer load sensor;
a pull load sensor;
an engine load sensor;
an overrunning sensor.
10. The brake valve arrangement according to claim 9 , wherein the overrunning sensor is connected with a memory device.
11. The brake valve arrangement according to claim 3 , wherein the brake valve has a valve actuator with a control pressure generation device, which comprises at least two solenoid valves.
12. The brake valve arrangement according to claim 2 ,
wherein the brake valve has a valve actuator with a control pressure generation device, which comprises three solenoid valves.
13. The brake valve arrangement according to claim 2 , wherein the brake valve has a control slide, which is connected in series with a compensation slide.
14. The brake valve arrangement according to claim 2 , wherein a control slide can be deflected in two opposite directions, in a neutral position generating a pressure in the range from 8 to 18 bar at an outlet (A) of the brake valve.
15. The brake valve arrangement according to claim 2 , wherein at a neutral position of a control slide, a connection exists from an outlet connection (A) of the brake valve to a tank connection (T).
16. The brake valve arrangement according to claim 2 , wherein the brake valve is flanged onto the at least one value module controlling the at least one controllable hydraulic consumer.
17. The brake valve arrangement according to claim 1 , wherein the at least two valve modules are detachable.
18. A brake valve arrangement of a vehicle having a trailer coupling and at least one controllable hydraulic consumer, the brake valve arrangement comprising a valve block having at least two valve modules, wherein at least one valve module controls the at least one controllable hydraulic consumer and at least one other valve module controls a wheel brake cylinder, wherein the at least one other valve module controlling the wheel brake cylinder is controlled by an electrical signal, wherein the electrical signal can be generated by a pressure sensor, which is coupled with a hydraulic brake system of the vehicle.
19. A brake valve arrangement of a vehicle having at least one controllable hydraulic consumer and a trailer coupling hydraulically connected to a wheel brake cylinder, the brake valve arrangement comprising a valve block having at least two valve modules, wherein at least one valve module is a control valve controlling the at least one controllable hydraulic consumer and at least one other valve module is a brake valve controlling the wheel brake cylinder via the trailer coupling.
