Definitions
- the invention relates to an electronically controlled brake system with traction control (ASR) and / or electronic stability program (ESP), with an actuation unit, wheel brakes and a control unit between the actuation unit and the wheel brakes, the control unit having at least one pump with a suction side and a pressure side and a ASR or ESP changeover valve between the suction side of the pump and the actuation unit, wherein a memory is arranged between the changeover valve and the suction side of the pump and at least one check valve is provided on the suction side of the pump.
- ASR electronically controlled brake system with traction control
- ESP electronic stability program
- ABS anti-lock braking system
- ASR slip control of the driven wheels
- ESP electronic stability program
- a generic brake system is known for example from German patent application DE 195 19 832 AI.
- a pulsation damper which serves to avoid large pressure fluctuations and to smooth out pressure peaks that can arise as a result of the brake control and put a heavy load on the brake system and can cause noise, has been integrated into a memory.
- the invention has for its object to further simplify or improve known brake systems, but in particular to reduce the required volume of the hydraulic or electronic control unit of the brake.
- At least one of the check valves on the suction side of the pump is additionally formed on the memory.
- the integration of the check valve in the accumulator eliminates the need to provide a mounting space for the valve elsewhere in the pump housing or at another point in the control unit, the accumulator and valve taken together practically not taking up much more space than a conventional accumulator alone.
- the combination of these components has the further advantage that a preassembled assembly is created, which is much cheaper in final assembly than two separate assemblies.
- the damping is only effective in the slip control of the drive wheels and in the automatic vehicle stability control, the volume requirements playing a rather subordinate role.
- 1 is a schematic circuit diagram of an electronically controlled brake system
- Fig. 2 shows a section through a first embodiment of a memory in which a check valve is arranged according to the invention
- Fig. 3 shows a section through a second embodiment of the memory of a brake system according to the invention.
- FIG. 1 shows an electronic brake system, such as is present in motor vehicles, for example, which in addition to an anti-lock braking system also has a traction control system (ASR) and / or an electronic stability program (ESP).
- ASR traction control system
- ESP electronic stability program
- a control unit 28 is arranged between an actuation unit 26 and the wheel brakes 27, said control unit not comprising lines, valves, 4 -
- a changeover valve 32 is provided between the suction side 30 of the pump 29 and the actuation unit 26.
- Several check valves 7, 8, 35 and at least one low-pressure accumulator 34 are arranged on the suction side 30 of the pump 29 in a known manner.
- a pulsation damper (not shown in FIG. 1) can also be provided between the changeover valve 32 and the suction side 30 of the pump 29.
- a space 1 for brake fluid is formed in a housing 25, said space sealingly delimiting on one side by a spring-loaded, displaceable piston 2 and on the other side via a channel 9 with the one shown in FIG 1 shown pump 29 is connected.
- the space 1 can also be connected to the wheel brakes 27 via a second channel 3.
- the check valve 7 is provided on the accumulator 34, in particular between the space 1 and the channel 3.
- the check valve 7 can be formed on the piston 2 with particular advantage.
- This combination of accumulator 34 and valve 7 is preferably designed in such a way that the piston 2 has an externally circumferential groove-like recess 10, into which an annular sleeve 11 with a sealing lip 12 abutting the wall of the space 1 is inserted, which is located between the channels 3 and 9 to the wheel brakes 27 or to the pump 29 acts as a check valve 7 with a pressure maintenance function.
- a pulsation damper is provided in the memory 34, which comprises an elastic membrane 4, a gas storage space 6, a support disk 16 for holding and clamping the membrane 4 in the piston 2 at the edge, and a bore 17 in the support disk 16.
- the membrane 4 is provided for damping pressure pulsations between the space 1 for brake fluid and a storage space 15 of the storage 34, which is preferably formed in the piston 2.
- the preferably designed as a throttle bore 17 between the storage space 15 and the gas storage space 6 serves for ventilation of the gas storage space 6.
- the support plate 16 serves as an abutment for a spring 18.
- the storage space 15 serves as a second abutment for the spring 18 Cover 19 which closes on the outside and is fastened in the housing 25 of the store 34 and preferably has an opening 20. Seals or retaining rings 21, 22 can be arranged between the piston 2 and the cover 19 on the one hand and the housing wall 25 on the other hand.
- the check valve 8 arranged according to the invention on the accumulator 34 is designed differently than the valve 7 in the embodiment according to FIG. 2. It has a channel 13 formed in the piston 1, which provides a possible connection between the channels 3 and 9 of the room 1 to the wheel brakes 27 shown in FIG. 1 or to the suction side 30 of the pump 29 also shown there.
- a closing member 14 is arranged in the form of a ball, which is biased in the closing direction by means of a spring 23 supported on a fastening disk 24 with a guide. All other details of FIG. 3 correspond to those of the exemplary embodiment according to FIG. 2. In the exemplary embodiment according to FIG. 3, only a second seal 21 is provided.
