Definitions
- the invention relates to an actuating unit according to the preamble of patent claim 1.
- Such an actuation unit for a wheel brake of a motor vehicle is already known (DE 195 27 936 AI), in which an electric motor which can be varied in speed drives a gear pump which releases pressure medium from a
- the known actuation unit is disadvantageous in that there is always a pressure medium-conducting connection to the reservoir when the brake is actuated.
- the actuation unit is therefore not a closed hydraulic system, which represents a considerable lack of safety.
- the reservoir must be of a relatively large size in order to provide a sufficient volume of pressure medium when the brake lining is badly worn.
- the actuation unit according to the invention with the features of claim 1 has the advantage that its functional reliability is increased because a closed hydraulic system is present.
- the same pressure medium volumes are always exchanged between the cylinder chamber of the cylinder-piston unit and the cylinder chamber on the side facing away from the brake lining.
- the changed piston position is compensated in this way even if the brake lining wears. If the hydraulic system is completely sealed, there is no need to add pressure medium. This simplifies the maintenance of the actuation unit, which is four times available in a car, for example.
- the actuating unit can also be mounted on the vehicle filled with pressure medium.
- An embodiment of the invention is shown in simplified form in the drawing as a circuit diagram of an actuation unit for a wheel brake of a motor vehicle and is explained in more detail in the following description.
- a motor vehicle not shown in the drawing, is equipped on its wheels with an actuating unit 1 for a wheel brake 2.
- the actuating unit 1 shown as a circuit diagram has a cylinder-piston unit 3, the cylinder 4 of which is penetrated in its entire length by a piston rod 5.
- a piston 6 arranged on this is formed with the same surfaces on both sides.
- the piston 6 separates two cylinder spaces 7 and 8 filled with a hydraulic pressure medium from one another in the cylinder 4.
- the piston rod 5 of the cylinder-piston unit 3 acts on at least one brake pad 9, which can be pressed against and lifted off from a friction element 10 connected to a vehicle wheel, in the case of a disk brake a brake disk.
- the actuating unit 1 includes a hydraulic pump 14 which can be driven by an electric motor 13 to vary its speed. This is on its suction side 15 by a suction line 16 with the cylinder chamber 7 on the brake lining side and on its pressure side 17 by a
- a return line 19 is provided, which connects the pressure line 18 to the suction line 16 and in which a 2/2-way valve 20 is arranged, which assumes its open position in a spring-actuated manner and can be controlled electromagnetically in its blocking position and in any intermediate positions.
- the suction side 15 of the pump 14 is connected to a small-volume pressure medium expansion tank 21 which is sealed from the atmosphere by an air and moisture-tight membrane 22.
- a measuring transducer 23, hereinafter referred to as a pressure sensor is connected to the pressure line 18 to measure the pressure in the cylinder chamber 8 facing away from the brake lining.
- the actuation unit 1 and the actuation units assigned to the other vehicle wheels can be controlled by the vehicle driver by means of a brake pedal 26, the pedal travel of which can be detected by a transducer 27, hereinafter referred to as a travel sensor.
- a transducer 27 hereinafter referred to as a travel sensor.
- an electronic control unit 28 is provided, with which the signal representing an electrical braking request signal of the displacement sensor 27 can be processed. With the control unit 28, the electric motor 13 and the directional control valve 20 are all
- Actuating units 1 of the vehicle controllable Furthermore, the signals measured by the pressure sensors 23 of the actuation units 1 can be processed in the control unit 28.
- the control unit 28 contains slip-dependent signals, which are detected on the vehicle wheels with wheel sensors (not shown), for the purpose of slip control, e.g. Can be processed for a brake lock protection, traction control or driving stability control of the vehicle.
- the actuation unit 1 has the following functionality:
- the control unit 28 puts the electric motor 13 of the pump 14 into operation and the directional control valve 20 is switched into its blocking position.
- the pump 14 draws in pressure medium from the cylinder chamber 7 on the brake lining side and conveys this into the cylinder chamber 8 of the cylinder-piston unit 3 facing away from the brake lining.
- the piston 6 with piston rod 5 is shifted to the left in the drawing and the at least one brake lining 9 against the friction element 10 pressed depending on the pump pressure.
- the variable-speed control of the electric motor 13 can Pressure rise rate can be set depending on the course of the brake request signal.
- the pressure acting in the cylinder space 8 is detected by the pressure sensor 23 and its signal processed in the control unit 28.
- the directional control valve 20 is controlled into an intermediate position so that the pressure medium conveyed by the pump 14 is discharged through the return line 13 to the suction side 15 of the pump while maintaining the brake pressure.
- the intermediate position of the directional control valve 20 is changed or this is switched to its open position. Due to the elasticity of the wheel brake 2, the piston 6 is reset and the pressure medium derived from the cylinder chamber 8 facing away from the brake lining is returned to the cylinder chamber 7 on the brake lining side.
- the gradient for pressure build-up and pressure reduction in the cylinder chamber 8 can be controlled. Furthermore, it is possible with the actuating unit 1 to control the brake pressure for the purpose of slip control when starting and braking, for driving stability control and for driver-independent braking.
- the pressure medium expansion tank 21 is not required per se, since the hydraulic system described is a is closed and when braking only pressure medium between the two cylinder spaces 7 and 8 is exchanged.
- the expansion tank 21 can be used to replace lost pressure medium at sealing points of the cylinder-piston unit 3 or the pump 14 or to compensate for heat-related volume fluctuations in the pressure medium in the system.
- the actuation unit 1 is a system that is self-sufficient for each vehicle wheel. Each is advantageous
- Actuating unit of the vehicle to a separate energy supply or groups of actuating units are connected to separate energy supplies. In the event of a power supply failure, the remaining actuation units remain functional.
