Abstract

The sensor-controlled anti-skid control valves 6,7 in a hydraulic brake system are also used in conjunction with sensor-controlled solenoid valve 14 connected in feed line 3 from master cylinder 2 and with accumulator 13 to provide anti-spin regulation. During the anti-skid control mode and when valves 6,7 are in the return position fluid from the brakes is passed to and stored in accumulator 11. During the anti-spin control mode, when valves 6,7 are as shown, valve 14 is switched over so that fluid from accumulator 13 actuates the brakes. To ensure that anti-spin regulation can take place, suction pump 12 which can operate at low inlet pressures, may under electronic control, intermittently draw fluid from accumulator 11 to change accumulator 13 or the connected brake circuit. At a predetermined minimum pressure at the inlet of accumulator 11, valve 16 opens to allow replenishment thereof from master cylinder 2. <IMAGE>

Description

SPECIFICATION Drive slip regulator The invention relates to a drive slip regulator for a vehicle, having a master brake cylinder and an anti-skid regulating system which varies the brake pressure at least at the wheel brakes of the driven wheels by means of at least one brake-pressure control valve, pressure medium being discharged into an accumulator chamber by means of the control valve(s) for the purpose of reducing the brake pressure and this discharged pressure medium being returned into the connection between the master brake cylinder and the brake-pressure control valve(s) by means of a return pump, and the drive slip regulator having a pressure accumulator in which braking medium is intermittently stored by means of the return pump for the purpose of actuating the brake when drive slip is detected, and a solenoid valve which shuts off communication between the master brake cylinder and the control valve(s) during drive slip regulation and connects the pressure accumulator to the inlet of the control valve(s) by means of which a variation in the brake pressure, controlled by a control circuit, is effected to suppress the drive slip.
It is known from German Offenlegungsschrift No.
21 39230 to use an anti-skid regulator and also a drive slip regulator in a vehicle and also to utilize parts of the electronic system of the anti-skid regulatorforthe drive slip regulator. It is also known (German Offenlegungsschrift No. 18 06 671 ) to suppress the drive slip by applying a braking pressure to retard the driven wheels.
The object of the invention is to reduce the cost of the drive slip regulator by utilizing components of the anti-skid regulator, but nevertheless to obtain a high-standard drive slip regulator.
According to the present invention there is provided a drive slip regulator for a vehicle, having a master brake cylinder and an anti-skid regulating system which varies the brake pressure at least at the wheel brakes of the driven wheels by means of at least one brake-pressure control valve, said control valves(s) acting to discharge pressure medium into an accumulator chamber connected thereto for the purpose of reducing the brake pressure, a return pump which returns said discharged pressure medium into a connection provided between the master brake cylinder and the brake-pressure control valve(s) and which intermittently stores braking medium for actuating the brake into a pressure accumulator connected to said pump, and a control circuit operatively connected to a solenoid valve which shuts off communication between the master brake cylinder and the control valve(s) during operation of the drive slip regulator and at the same time connect the pressure accumulator to the inlet of the control valve(s) whereby the control circuit can effect a controlled variation of the brake-pressure to suppress the drive slip, and in which the return pump is in the form of a suction pump, and there is connected between the master brake cylinder and the inlet ofthe return pump a connection line incorporating a change-over valve which establishes communication between the master brake cylinder and the return pump when the pressure at the inlet of the return pump drops below a predetermined value.
Thus, the teaching of the invention is to utilize the anti-skid regulating valves of the driven wheels and also the return pump for anti-slip regulation. The solenoid valve which has been mentioned is also required to isolate the master brake cylinder and to connect the pressure accumulator to the brake circuit of the driven wheels. The invention also provides an advantageous method of ensuring that the pressure accumulator has been, or is being, adequately charged.
The invention will be further illustrated with reference to the accompanying drawings, in which: Figure 1 shows in diagrammaticform a driven pair of wheels together with the hydraulic components for anti skid regulation and drive slip regulation; Figure 2 shows an embodiment of the changeover valve of Figure 1; Figure 3 shows an embodiment of the construction of the return pump of Figure 1; Referring to Figure 1, a master brake cylinder actuated by means of a brake pedal 1 is designated 2 and its outlet is connected to the brakes of driven wheels 4 and 5 by way of the brake line 3. Brake pressure regulating valves 6 and 7 are connected downstream ofthejuntion of the brake line and, in the present instance, they are so-called three-port, three-position valves by means of which the pressure at the brakes can be increased, held constant and reduced.The non-return valves 8 and 9 are known auxiliary components which are of no concern here.
For the sake of simplicity, the control circuit for the valve in the event of anti-skid regulation, and the sensors on the wheels, are not illustrated.
When the pressure at the brakes is reduced during anti-skid regulation, pressure medium flows to the accumulator chamber 11 by way of the line 10. A return pump 12 is switched on intermittently and returns this pressure medium into the brake line 3.
Referring to the drawing, a pressure accumulator 13, a solenoid valve 14, a pressure-controlled change-over valve 16, an excess-pressure valve 17 and a pressure switch 18 are provided for regulation upon the occurrence of drive slip.
When drive slip occurs, the solenoid valve 14 is changed over by a control circuit (not illustrated), so that the pressure of the pressure accumulator 13 then acts upon the brakes of the wheels 4 and 5. The pressure level is likewise varied by means of the control valves 6 and 7 which are acted upon by the control circuit which is not illustrated, but which is known in principle, in dependence upon the detected drive slip.
However, it must be ensured that the pressure accumulator has been, or is being, charged for the purpose of drive slip regulation. For this purpose, in accordance with a further proposal, the pump 12 is a suction pump and is not a free piston pump, as is preferred in the case of anti-skid regulators. If the pressure in the pressure accumulator 13 is inadequate upon change-over of the solenoid valve 14, the pump 12 is switched on directly by means of the pressure sensor 18 or indirectly by way of the electronic control device, and pressure medium is fed into the pressure accumulator 13 or into the connected brake circuit. This is effected by the suction pump 12 even in the case of low pressure in the accumulator chamber 11 in which case a free piston pump would no longer deliver.In orderto ensure delilvery even when the pressure medium discharged by the valves 6 and 7 has been largely returned, the pressure-controlled changeover valve 16 is provided which opens when a pre-determined minimum pressure has been reached at the outlet of the accumulator chamber 11 and allows pressure medium to flow from the master brake cylinder 2 to the accumulator chamber 11 to ensure repienish ment.The non-return valve 17 ensuresthatthe pressure between the solenoid valve 14 and the valves 6 and 7 or the wheel brakes does not become excessive. It opens at a predetermined pressure difference of for example, 250 bar.
Figure 2 shows an embodiment of the changeover valve 16, only the essential parts thereof being illustrated. The line 3 is connected at 20 and the accumulator chamber 11 is connected at 21. The closure member 23 is loaded by a spring 24 and interrups communication between the ports 20 and 21 provided that it is not held open by the piston 25.
One end of the piston 25 is subjected to the pressure in the accumulator chamber 11 plus the pressure of the spring 24, and its other end is subjected to the pressure of a spring 26 and also to the pressure in the accumulator chamber 11 (port 22). The springs 24 and 26 and the effective surfaces of the piston 25 are dimensioned such that, when the pressure in the accumulator chamber 11 drops below a predetermined value, the force acting on the piston 25 by the spring 26 preponderates, and thus the closure member 23 is moved to the open position. An abrupt increase in pressure in line 3 from the master brake cylinder (port 20) during braking, acts to move the piston 25 against the pressure of springs 26, and the pressure of spring 24 acts to move the closure member 23 to reclose the valve 16 between the ports 20 and 21. It will be appreciated that the solenoid valve 14 is also switched back upon actuation of the brake pedal.
Figure 3 shows the pump 12 constructed as a suction pump. An eccentric is designated 30, the pump piston loaded by the spring 32 is designated 31, and the suction valve and the pressure valve are designated 33 and 34 respectively. When the piston 31 is dispaced to the right when the eccentric 30 is in a corresponding position, pressure mdium is drawn by way of the valve 33 from the accumulator chamber 11 connected at 35. When the piston 31 is subsequently displaced by the eccentric 30, pressure medium flows through the valve 34 to the pressure accumulator 13 connected at 36, or to the wheel brakes.
