Definitions
- the invention relates to a hydraulic motor
- a brake system of the aforementioned type has already become known, with a pressure medium source to which a main pressure line is connected, which leads to a wheel brake.
- the wheel brake is in turn connected to a pressure medium drain line, which leads to a low-pressure accumulator via an electromagnetically actuated outlet valve.
- a hydraulic pump connects downstream of the low-pressure accumulator and feeds the pressure medium from the low-pressure accumulator back to the main pressure line, which is connected to a brake pressure sensor. Both the brake pressure sensor and the hydraulic pump are to be regarded as a source of pressure medium for supplying the wheel brake.
- an electromagnetically actuable inlet valve which is downstream into the main pressure line
- Shift valve follows.
- This switching valve can be operated hydraulically depending on the pressure difference before and after the inlet valve.
- the switching orifice function is therefore subject to the influence of the dynamic pressure drop within the intake valve. Accordingly, a relatively high switching pressure is required to operate this switching orifice valve, which it is advisable to lower.
- FIG. 2 shows a first embodiment of the control panel, integrated in an electromagnetically actuated inlet valve of the brake system
- Fig. 3 shows another design embodiment of the control panel.
- FIG. 1 shows the features essential to the invention, according to which a main pressure line 6 is connected to a pressure medium source 10 and leads to a wheel brake 8. With a pressure medium drain line 7 connected to the wheel brake 8 and leading to a reservoir 19, in which a pressure modulation valve 20 is closed as the wheel brake side in the basic position Exhaust valve is arranged. Upstream to the connection of the pressure medium drain line 7 to the main pressure line 6 is located in the main pressure line 6
- Switching valve 1 to which a pressure chamber 2 is assigned according to the invention, to which non-return valves 3, 4 are connected.
- One of the check valves 4 has the task of separating a pressure medium branch 5, which is attached upstream to the switching valve 1 on the main pressure line 6, from the pressure chamber 2.
- the further check valve 3 connects the connection of the pressure medium drain line coming from the wheel brake 8 to the pressure chamber 2.
- an actuator 9 in the pressure chamber 2 which is guided in a sealed manner therein and is symbolically represented as an actuating piston.
- this actuator 9 is coupled to the switching valve 1 via a rod. In one operating direction of the switching valve 1, the piston of the actuator 9 is acted upon by the pressure medium branch 5 exclusively by the pressure of the pressure medium source 10, while in the opposite operating direction - after opening the
- Pressure modulation valve 20 the pressure change and thus the pressure drop in the pressure chamber 2 is effective for switching on the diaphragm function.
- the actuator 9 and thus the switching valve 1 is positioned in its ineffective basic position.
- the switching valve 1 remains in the throttle-free position shown in the illustration.
- the check valve 4 which is permanently connected to the pressure medium source 10, is used in a separate line connection to the pressure chamber 2.
- An electromagnetically actuated inlet valve (pressure modulation valve 17) is also shown upstream of the switching valve 1.
- Pressure modulation valve 17 can be supplemented by a precise pressure maintenance phase if desired or required.
- the switching diaphragm valve 1 with the actuator 9 and the check valves 3, 4 forms an integrated, space-optimized unit, which is explained in the construction of FIG. 2 below.
- FIG. 2 shows a partial sectional view through a pressure modulation valve 17 used as a cartridge valve in a valve block housing 21.
- the valve tappet 16 connected to the magnet armature 22 extends through a magnet core 23 into a cavity of the valve cartridge 24, in which a sleeve-shaped valve seat body 18 is fastened in the lower part .
- the valve seat body 18 is connected at its lower section to the likewise tubular and stepped valve cartridge 24, an annular space 25 remaining between the valve seat body 18 and the valve cartridge 24, in which an annular sleeve forming the check valve 4 is arranged.
- Above the Check valve 4 is the actuator 9, which forms with the check valve 4 an annular piston 12 sealed in the annular space 25 of the valve cartridge 24.
- the sealing lip on the annular piston 12 is directly exposed to the pressure of the pressure medium source 10, while the further check valve 3 is arranged in the form of an annular sleeve on the sleeve-shaped section above the annular piston 12.
- the check valve 3 shuts off the pressure chamber 2 located between the two ring sleeves in the direction of the section of the main pressure line 6 leading to the wheel brake 8.
- This check valve 3 is fixed in the valve cartridge 24 by means of a ring part 13 fixed to the housing.
- the check valve 3 allows only a pressure medium flow from the pressure medium source 10 via the valve tappet 16, which is lifted from the valve seat body 18, to the wheel brake 8 and into the pressure chamber 2.
- the pressure chamber 2 is structurally limited by the sleeve-shaped actuator 9 and the ring sleeves resting against the wall of the valve cartridge 24. At the same time, the pressure chamber 2 receives the spring 11, which rests with its one spring end on the collar of the actuator 9 and with the other spring end on a support ring of the check valve 3.
- a through hole in the valve cartridge 24 at the level of the pressure chamber 2 leads to the pressure modulation valve 20 which is closed in the basic position and in the blocking position of which pressure medium from the pressure medium source 10 is clamped between it and the pressure chamber 2.
- a hydraulic pressure force is sufficient in the pressure chamber 2, which can be smaller by the spring force than the hydraulic pressure force generated by the pressure medium source 10 during normal braking.
- the ring piston 12, which acts as a switching piston, is only displaced in the direction of the magnetic core 23 after the in Basic position blocked pressure modulation valve 20 allows pressure medium to escape from the pressure chamber 2 to the reservoir 19.
- the passage cross-section between the sleeve-shaped end and the end face of the magnetic core 23 facing it is reduced to the size of one or more aperture openings 14, so that the fluid coming from the pressure medium source 10 in throughput to the wheel brake 8 is limited.
- the throughput through the control panel can be adjusted both by the sleeve distance of the actuator 9 from the magnetic core 23 and by a corresponding structural modification, for example in a photo-technical way by etching the aperture openings 14 and aperture channels in a thin sheet metal part 15 lying against the magnetic core 23. It can thus be made inexpensively any desired options by manufacturing thin sheet metal parts 15 with different aperture openings 14.
- the aperture 14 can be introduced, for example, as a bore or notch in the sleeve-shaped end of the actuator 9.
- the switching pressure of the orifice valve 1 into the orifice position is relatively small, since 3.4 large ring sleeves can be used due to the design of the check valves, the low force of the spring 11 being relatively small and thus being advantageous for the switching behavior in the orifice position.
- the switching valve 1 is now independent of the dynamic pressure drop across the the electromagnetically actuated inlet valve is to be switched to the orifice position, the calibration measures previously customary, for example by using ballasts, can be omitted. Considering a very small changeover pressure in the aperture position, a reliable, comfortable function results.
- FIG. 3 shows an expedient embodiment of the switching valve 1 integrated in a preferably block-shaped valve block housing 21 of the slip-controlled brake system.
- the receiving housing for the switching valve 1 has a blind bore into which a main pressure line 6 connected to the wheel brake 8 opens out and via which a check valve 3 adjacent to the section of the main pressure line 6 connects to the pressure chamber 2.
- the pressure medium drainage line 7 which opens laterally into the pressure chamber 2 is connected to the pressure modulation valve 20.
- the check valve 3 is equivalent to the embodiment of FIG. 2 designed as a ring sleeve which is attached to a sleeve-shaped ring part 13 which is fixed between a bore step and a cover 27 closing the blind bore.
- the ring part 13 receives in its interior a ring filter 28 which keeps contaminants of the pressure medium coming from the wheel brake 8 away from the orifice openings 14.
- a plate filter 29 At the end of the blind bore there is also a plate filter 29, which also ensures that contaminants introduced into the main pressure line 6 from the pressure medium source 10 are kept away from the annular piston 12 and thus from the check valves 3, 4 and the orifice openings 14.
- the annular piston 12 is sleeve-shaped over almost its entire section, so that it accommodates the spring 11 in its interior, which is supported on the end face of the cover 27 with its end facing away from the annular piston 12.
- the diaphragm openings 14 are embedded in a thin sheet metal part 15 by means of an etching process, which is clamped between the ring part 13 and the cover.
- one or more aperture openings 14 are made in the end region of the sleeve-shaped section on the annular piston 12. From the drawing it can be seen that the sleeve-shaped section on the ring piston 12 is guided in the ring part 13.
- the ring sleeve (check valve 4) acted upon by the pressure medium in the main pressure line 6 in the closing direction immediately after the plate filter 29 is also buttoned like the check valve 3 in a recess in the enlarged area of the ring piston 12.
- the region of the annular piston 12 receiving the check valve 4 is supported on the plate filter 29.
- the pressure medium reaches the wheel brake 8 via the hollow area of the annular piston 12 and the ring filter 28, as well as via the gap between the sealing lip on the check valve 3 and the housing wall into the pressure chamber 2
- Pressure medium propagates from there via the pressure medium outlet channel 7 to the pressure modulation valve 20 which is closed in the basic position. Since the same brake pressure on both sides of the check valve 4 is present and the annular piston 12 is pressure-balanced, it remains in the basic position shown in the illustration.
- Diaphragm opening cross-section 14 is significantly smaller than the opening cross-section of the pressure modulation valve 20, the pressure in the wheel brake 8 relaxes in the direction of the unpressurized reservoir 19, which corresponds to the low-pressure accumulator in a brake system operating according to the return flow principle.
- the switching position of the switching valve 1 described now ensures that the brake pressure is reduced in the associated wheel brake 8. A renewed build-up of brake pressure in the wheel brake 8 requires the reversal of the
- Pressure modulation valve 20 in the blocking position, whereby the annular piston 12 is returned to its basic position shown in the illustration by refilling the pressure chamber 2 under the action of the spring 11.
- a quick release of the wheel brake 8 is ensured by the overflow of the two check valves 3, 4 in the direction of the pressure medium source 10 as soon as the pressure level in the
- Pressure medium source 10 ie is lowered in the master cylinder by releasing the brake pedal.
- FIG. 3 there is a particularly compact structural unit for the switching valve 1, since all essential, previously described individual elements can be arranged rotationally symmetrically and coaxially interleaved in a blind bore. The same arrangement features also result for the embodiment according to FIG. 2.
