Definitions
- Hydraulic brake system for road vehicles especially Perspnen motor vehicles
- the invention relates to a hydraulic brake system according to the preamble of claim 1.
- Such a hydraulic brake system with a master brake cylinder is already known from DE 43 43 386 AI, which has a displaceable piston which acts on a travel simulator spring when the service brake is actuated.
- the spring consists of an elastomer with closed-pore, gas-filled cells. It produces a progressive pedal characteristic, ie with increasing brake pedal travel, a progressively increasing counterforce becomes effective. Moving the piston when the pedal is actuated is only possible if pressure medium can be displaced into the reservoir from the second pressure chamber of the master brake cylinder. For this purpose, a line connection is created, which leads out of the master brake cylinder, an electromagnetic one contains switchable shut-off valve and leads into the pressure medium reservoir.
- an electronic control unit is provided for controlling this shut-off valve, the servo pressure source and further solenoid valves serving for brake pressure modulation in wheel brake cylinders.
- the control device is required to control the shut-off valve, which makes the brake system more expensive.
- the hydraulic brake system according to the invention with the characterizing feature of claim 1 has the advantage that the electromagnetically switchable shut-off valve is replaced by a mechanically controlled one, which allows the control device to be simplified.
- the first valve is closed when the service brake is effective, so that the third valve keeps the connection between the second pressure chamber of the master brake cylinder and the pressure medium reservoir open and the travel simulator spring is actuated. If, on the other hand, the service brake has failed and the first pressure chamber of the master brake cylinder is connected to the brake circuit, the third valve blocks the exchange of pressure medium from the second pressure chamber with the pressure medium reservoir after a partial stroke of the first piston.
- the path simulator spring is therefore not effective.
- the development of the brake system according to the invention according to claim 3 is characterized by a high functional reliability of the third valve due to the mechanical coupling of the tappet to the first piston.
- the embodiment of the invention characterized in claim 5 specifies a path simulator spring which is resistant to pressure medium and which maintains constant properties over the life of the vehicle.
- FIG. 1 shows a circuit diagram of a hydraulic brake system for Passenger cars
- Figure 2 shows a longitudinal section through a master cylinder used in the brake system as a first embodiment
- Figure 3 shows a longitudinal section through a modified master cylinder as a second embodiment.
- a hydraulic brake system 10 for passenger cars shown in FIG. 1 has one of the wheel brakes 11, 12
- the brake system 10 thus has an externally powered service brake.
- the brake system 10 also includes a muscle-operated auxiliary brake. This has a master brake cylinder 17 which can be actuated by a brake pedal 16 and has a pressure medium reservoir 18.
- Master cylinder 17 is single-circuit, i. H. it is connected to the brake circuit I through a line 19 and a first valve 20 arranged therein. In the drawn position of the valve 20, the auxiliary brake therefore only acts on the wheel brakes 11 and 12 of the front axle VA. When the service brake is effective, the valve 20 blocks the connection between the master brake cylinder and the wheel brakes 11 and 12.
- the first valve 20 associated with the master brake cylinder 17 is therefore referred to below as a shut-off valve.
- the servo pressure source 15 sucks pressure medium from the reservoir 18 of the master brake cylinder 17 and tensions it at high pressure for the function of the service brake in front. Pressure medium removed from the wheel brakes 11 to 14 during the operation of the service brake is returned to the reservoir 18. To shut off the brake circuit I against the pressure medium reservoir 18 with an effective auxiliary brake is in a to
- each wheel brake 11 to 14 is assigned two valves 25 and 26 for brake pressure modulation when the service brake is effective.
- the brake system 10 is equipped with an electronic control unit 29, to which, in addition to the valves 20, 24, 25 and 26, a travel sensor 30 which detects the travel of the brake pedal 16 and six pressure sensors 31 to 36 are connected, with which the pressure generated by the master brake cylinder 17 is connected, the pressure provided by the servo pressure source 15 and the pressures controlled in the wheel brakes 11 to 14 can be detected.
- the service brake acts electro-hydraulically, ie when the brake pedal 16 is actuated by the driver of the passenger car, the electrical travel signal detected by the travel sensor 30 and possibly further electrical signals from the electronic control device 29 for controlling the Valves 20, 24, 25 and 26 are evaluated in order to generate brake pressure in the wheel brakes 11 to 14 in accordance with the braking request, which is monitored by the control unit based on the electrical signals from the pressure sensors 31, 33 to 36.
- a first piston 40 can be seen therein, which has a push rod 41 protruding from the master brake cylinder for the application of the brake pedal 16.
- the first piston 40 is therefore referred to below as a angtang piston.
- a second piston 42 is arranged floating in the master brake cylinder 17; it is mentioned below as a floating piston.
- a first pressure chamber 43 filled with pressure medium. This is connected to the line 19 of the brake circuit I by a connection 44.
- the floating piston 42 delimits a second pressure chamber 45, likewise filled with pressure medium, in which helical compression springs 46, 47 of the travel simulator 37 are arranged.
- the helical compression springs 46, 47 connected in series are supported on the one hand on the floating piston 42 and on the other hand on the master brake cylinder 17.
- a compression spring 48 is also received in the first pressure chamber 43, which on the one hand engages the rod piston 40 and on the other hand is supported on a stop ring 49 for the floating piston 42.
- Floating pistons 42 are supported on a stop 50 of the master brake cylinder 17 due to the action of the path simulator springs 46, 47 on the stop ring 49 and the rod piston 40 due to the spring force of the compression spring 48.
- the first pressure chamber 43 and the second pressure chamber 45 are connected to the pressure medium reservoir 18 in the drawn position of the two pistons 40 and 42.
- a connecting piece 53 of the master brake cylinder 17th outgoing connecting bores 54 and 55 are provided for receiving the pressure medium reservoir 18.
- the connecting bore 54 opens on the rod piston 40 into a circumferential groove 56 which is connected to an opening 57 in the rod piston.
- the rod piston 40 has a coaxial through bore 58, which opens into the first pressure chamber 43.
- the through bore 58 which is open in the rest position of the rod piston 40, can be shut off by a central valve 59 with a small piston stroke. This central valve 59 forms the second valve assigned to the master brake cylinder 17.
- the floating piston 42 is also provided with a coaxial through hole 61.
- a valve seat 62 of a seat valve 63 is formed in the floating piston 42.
- a transverse bore 64 extends from the through bore 61 and opens into a circumferential groove 65 of the floating piston 42. This is sealed on both sides against the jacket 66 of the master cylinder 17. Since the aforementioned connection bore 55 meets the circumferential groove 65 at least in the rest position of the floating piston 42, there is therefore the aforementioned pressure-medium-conducting connection between the second pressure chamber 45 and the pressure-medium reservoir 18.
- a tappet 69 with a closing body 70 matched to the valve seat 62 belongs to the third seat valve 63 forming the valve associated with the master brake cylinder 17.
- the tappet 69 is guided in a longitudinally movable and sealed manner from the side of the rod piston 40.
- the plunger 69 has a collar 71 facing away from the closing body, with which it is received in the first pressure chamber 43 in a sleeve-shaped extension 72 of the rod piston 40.
- there is a shackled compression spring 73 which on the one hand Forms the closing spring of the central valve 59 and, on the other hand, holds the collar 71 of the tappet 69 on the base on the shoulder 72.
- the compression spring 73 allows the plunger 69 to move in the direction of the rod piston 40.
- the closing body 70 is at a greater distance from the valve seat of the seat valve 63 than the closing stroke of the central valve 59.
- the closing stroke of the seat valve 63 switching the connection of the second pressure chamber 45 to the pressure medium reservoir 18 is greater than the closing stroke of the central valve 59 switching the connection of the first pressure chamber 43 to the pressure medium reservoir.
- the central valve 59 depends on the stroke of the rod piston 40 switching; due to the mechanical coupling of the plunger 69 with the
- Rod piston 40 also applies to the seat valve 63.
- the second embodiment of the master cylinder 17 shown in Figure 3 is largely identical to that of Figure 2. It differs essentially only in that the floating piston 42 and the path simulator springs 46, 47 are arranged in a sleeve-shaped screw-in part 76, which is on the side facing away from the pedal the master brake cylinder 17 is screwed into it.
- the screw-in part 76 has at least one opening 77 on the circumferential side, which is connected on the one hand to the circumferential groove 65 of the floating piston 42 and on the other hand to the connecting bore 55 to the pressure medium reservoir 18 of the master brake cylinder 17.
- the two embodiments of the master brake cylinder 17 are designed for a single-circuit auxiliary brake.
- the arrangement of the Travel simulator 37 in the master brake cylinder 17 can also be used in brake systems with two brake circuits of the auxiliary brake.
- another piston, the separating piston is arranged between the rod piston 40 and the floating piston 42, which separates the first pressure chamber 43 from a second pressure chamber on the floating piston side.
- This second pressure chamber is connected to the second brake circuit of the auxiliary brake.
- the tappet 69 of the seat valve 63 is coupled to the separating piston.
- a two-circuit master brake cylinder 17 consequently has a greater overall length than a single-circuit.
- the screw-in part 76 of the second exemplary embodiment can therefore advantageously be used in such a two-circuit master brake cylinder because the fine machining of the
- the master brake cylinder 17 has the following mode of operation in the context of the hydraulic brake system 10: With more effective
- Service brake separates the shut-off valve 20 in line 19, the connection of the first pressure chamber 43 to the brake circuit I. After a short stroke of the rod piston 40, the central valve 59 closes the connection of the first pressure chamber 43 to the pressure medium reservoir 18. Since the closing stroke of the
- the pressure medium enclosed in the first pressure chamber 43 forms a hydraulic column which, when the rod piston 40 is displaced further, simultaneously displaces the floating piston 42. This is possible because pressure medium from the second pressure chamber 45 through the through hole 61, the open seat valve 63, the transverse hole 64, the circumferential groove 65 and the connecting hole 55 can flow to the pressure medium reservoir 18.
- the circumferential groove 65 is formed axially so long that this pressure medium-conducting connection exists even at the maximum stroke of the floating piston 42.
- the two shut-off valves 20 and 24 assume the position shown in FIG. 1.
- the rod piston 40 is displaced and the central valve 59 is closed, as described above.
- pressure medium is displaced from the first pressure chamber 43 through the line 19 and the shut-off valve 20 into the brake circuit I and brake pressure is generated in the wheel brakes 11 and 12. Due to the
- the closed seat valve 63 prevents pressure medium from flowing out of the second pressure chamber 45 to the pressure medium reservoir 18.
- the floating piston 42 thus remains in its initial position tensioning of the helical compression springs 46, 47 is omitted.
- the path simulator 37 therefore has no function when the auxiliary brake is effective.
- the pedal characteristic is thus generated essentially by the elasticity of the elements of the brake system 10 belonging to the auxiliary brake.
