Definitions
- the invention relates to an electronically controllable brake actuation system for motor vehicles with a master brake cylinder which can be actuated by means of an actuation pedal and has at least one piston, with at least one brake pressure transmitter which can be controlled by an electronic control unit, and which are directly connected to the wheel brakes of the vehicle Can be connected to the master brake cylinder via at least one hydraulic connection that can be shut off by means of a valve device, with at least one sensor device for recognizing the driver's deceleration request, and with a simulator chamber that interacts with the master brake cylinder.
- Such a brake actuation system is such. B. from the earlier application of the applicant P 4413579 known.
- the pressure chambers of the master brake cylinder designed as a tandem master brake cylinder are assigned two simulator chambers, which are connected to the pressure chambers with the interposition of a parallel combination of an electrically controllable, preferably normally closed (SG) 2/2-way valve with one to the master brake cylinder non-return valve are connected.
- an electrically controllable preferably normally closed (SG) 2/2-way valve with one to the master brake cylinder non-return valve
- a disadvantage of the known brake actuation system is that the electromagnetically actuated 2/2-way valves, which have to be energized each time the system is actuated, often leak during operation and thus represent a potential source of interference. It is therefore an object of the present invention to improve an electronically controllable brake actuation system of the type mentioned at the outset in such a way that its operational reliability is increased in particular. At the same time, the switching of such a system should be considerably simplified.
- a first solution to this problem is that the simulator chamber is connected to a hydraulic space delimited by a further piston in the master brake cylinder by means of a lockable connection.
- An advantageous further development of the subject matter of the invention provides that the simulator chamber is connected to an annular space which is delimited by the further piston in the master brake cylinder and which is connected to the hydraulic space so that it can be shut off.
- a second solution of the task on which the invention is based provides that the simulator chamber in the main brake cylinder is formed separately from its pressure chamber, delimited by a further piston and by means of a lockable connection to a pressure-free pressure medium connected to the pressure chambers of the master brake cylinder ⁇ storage container is connected.
- FIG. 1 shows a circuit diagram of a first embodiment of the brake actuation system according to the invention
- FIG. 2 shows a second embodiment of the master brake cylinder which can be used in the context of the brake actuation system according to the invention, partly in section, and
- Fig. 3 shows a portion of that shown in Fig. 1 or 2
- the electronically controllable brake actuation system is intended for a vehicle with a front wheel drive. It consists of a two-circuit master brake cylinder or tandem master cylinder 2 which can be actuated by means of an actuation pedal 1 and which has pressure chambers 17, 19 which are delimited from one another by two rubbers 18, 20 and which are connected to an unpressurized pressure medium reservoir 3.
- the first pressure chamber (primary pressure chamber) 17 is by means of a lockable first hydraulic line 11 on the one hand with a first electrically controllable brake pressure sensor 4, to which a z. B.
- the hydraulic wheel brake 7 assigned to the front axle is connected, and on the other hand to a first pressure chamber 41 of a preferably dual-circuit third brake pressure transducer 6 in connection to which one of the other vehicle axles, preferably the non-driven rear axle, is associated with the wheel brake 9 closed is.
- the line is shut off by means of a first solenoid valve 13a, while a second solenoid valve 15a is inserted in the line section leading to the third brake pressure transmitter 6.
- the second Pressure chamber (secondary pressure chamber) 19 is connected via a lockable second hydraulic line 12 on the one hand to a second electrically controllable brake pressure sensor 5, to which the other hydraulic wheel brake 8 assigned to the front axle is connected, and on the other hand to a second pressure chamber 42 of the third brake pressure sensor 6 in connection, to which the other wheel brake 10 associated with the rear axle is connected.
- the line 12 is shut off by means of a third solenoid valve 13b, while a fourth solenoid valve 15b is inserted into the line section leading to the third brake pressure transmitter 6.
- the second (secondary) pressure chamber 19 of the master brake cylinder 2 is separated from a third pressure chamber 27 by a third piston 28, which at the same time delimits an annular space 33.
- a simulator chamber 14, which is delimited by a spring-loaded hydraulic piston 16, is connected to the annular space 33, which is connected to the third pressure space 27.
- the third piston 28 is preferably designed in two parts and consists of an outer piston 29 and an inner piston 30, which is sealed in the outer piston 29 and is biased against the actuation direction of the master brake cylinder 2 by means of a compression spring 32 and axially abuts the outer piston 29, so that it can be taken along by the latter.
- the outer piston 29, which is preloaded by means of a second compression spring 31, has a plurality of radial bores 38 which are evenly distributed on its circumference and which open in the annular space 33 and which enable the aforementioned connection between the latter and the third pressure space 27.
- the bores 38 can move from one on the inner piston 30 arranged sealing sleeve 39 are run over, so that the connection is interrupted.
- the relative movement between the inner 30 and the outer piston 29 can be achieved by axially abutting the second master cylinder piston 20 against an axial extension 40 of the inner piston 30 or by a force transmission between the two parts, in particular in the event of a failure of the secondary space 19 , or the valves 13, 15 or if the valves 13, 15 have not been switched, are introduced.
- the structure of all three brake pressure transmitters 4, 5, 6 is basically the same and each consists of a hydraulic cylinder 24, 25, 26, in which a piston 34, 35, 36 + 37 is displaceably guided through one preferably reversible DC motor 44, 45, 46 can be driven.
- the common control of the DC motors 44, 45, 46 and the solenoid valves 13a, b, 15a, b is served by an electronic control unit (not shown), which receives as input signals the output signals of a brake light switch 48 which interacts with the actuating pedal 1, and two pressure sensors 43, 47 which are connected to the pressure chambers 17, 19 of the tandem master cylinder 2 and which enable driver deceleration request detection. It is particularly advantageous if the pressure sensors 43, 47 are designed as components of the hydraulic control unit.
- a force sensor which senses the actuating force on the actuating pedal 1
- a force sensor which senses the actuating force on the actuating pedal 1
- Information about the actuation path of the brake pressure sensor pistons 34, 35, 36 can be supplied to the control electronics as further input signals of path or position sensors 21, 22, 23, which are only indicated schematically.
- the individual wheels (not shown in FIG. 1) are assigned to the wheel sensors, the output signals of which correspond to the driving speed and are fed to the electronic control unit as further input variables.
- the filling of the wheel brakes 7-10 is carried out in a known manner by the pressure transmitters 4, 5 and 6.
- the following relationships apply to the forces F lf F 2 of the compression springs 31, 131 and 32, 132, which prestress the outer pistons 29, 129 and the inner pistons 30, 130, respectively:
