Abstract
The invention relates to a device for controlling and regulating a required pressing force from a current collector of a vehicle on an overhead line, a method for using such a device and a vehicle having at least one such device, wherein the device has a base control circuit, an additional control circuit and a working pressure control circuit. The base control circuit has a base control circuit adjustment device for adjusting a base pressure from a provided power pressure and the additional control circuit has a control device for adjusting an additional pressure from a provided power pressure, wherein the base pressure and the additional pressure act together to form a working pressure and to provide the required pressing force.
Claims14
A device for controlling a pressing force which is from a current collector of a vehicle and acts on an overhead line, wherein the pressing force is actuated by a pneumatic or hydraulic working pressure, the device comprising:
- a basic control circuit;
- an additional control circuit,
- wherein the basic control circuit has a basic control circuit setting device which is configured to set a basic pressure from a power pressure which is made available,
- wherein the additional control circuit has a regulator which is configured to set an additional pressure from a power pressure which is made available, and
- wherein the basic pressure and additional pressure are each input into and combined at a setting device to output a working pressure into a working pressure control circuit.
A method for controlling a pressing force which is from a current collector of a vehicle and acts on an overhead line, wherein the pressing force is actuated by a pneumatic or hydraulic power pressure, the method comprising:
- setting a basic pressure in a basic control circuit;
- setting an additional pressure in an additional control circuit;
- inputting adding the basic pressure and the additional pressure in a setting device;
- and
- introducing a working pressure into a working pressure control circuit,
- wherein the added pressure sets the working pressure.
A method for controlling a pressing force which is from a current collector of a vehicle and acts on an overhead line, wherein the pressing force is actuated by a pneumatic or hydraulic power pressure, wherein the power pressure is regulated by a pressure from a pilot control circuit, the method comprising:
- setting a pilot control basic pressure in a basic control circuit of the pilot control circuit to set the normal pressing force;
- setting a pilot control additional pressure in an additional control circuit of the pilot control circuit to set an additional pressing force;
- adding the pilot control additional pressure to the pilot control basic pressure, each input in a setting device, to form a resulting pressure in accordance with the respective driving situation;
- and
- regulating the power pressure by means of the added pressure.
