Definitions
- a torque transmission device with at least two, in particular "normally closed” formed, clutches and at least one primary switching group with an idle position, a first and a second switching position proposed.
- the torque transmission device has a hydraulic circuit according to an embodiment of the invention.
- the safety valve is switched due to a failure of the electrical system.
- FIG. 1 shows a hydraulic circuit of a torque transmission device of a motor vehicle with two clutches, two primary switching groups and four secondary switching groups according to the prior art in a circuit diagram
- 2 shows a hydraulic circuit according to an embodiment of the invention for a torque transmission device as shown in FIG. 1 in a circuit diagram representation
- Fig. 3 shows a hydraulic circuit according to another embodiment of
- FIGS. 1 to 3 each show a hydraulic circuit 1 or 100 for a torque transmission device of a motor vehicle that is identical in itself, designed as a dual-clutch transmission, which has two clutches 2 and 3, one for switching a gearshift stage of a planetary gear set, primary shifting group 7. a formed as Doppelstirnradlane, primary switching group 9, three trained as Doppelstirnradmen, secondary switching groups 5, 6 and 8 and designed as a wave connecting stage, secondary switching group 4 and a not provided with reference numerals parking brake.
- FIG. 1 shows a hydraulic circuit 100 known from the prior art.
- Conventional hydraulic transmission circuits 100 for motor vehicle transmission devices are designed such that the tank lines 402-409 are connected directly to the low pressure reservoir 40 of the hydraulic circuit 100 to relieve a prior pressurization are .
- the low-pressure tank 40 serves as a hydraulic fluid reservoir for the pump 32, which provides a high-pressure hydraulic fluid in the hydraulic circuit 100, which hydraulic fluid can be stored in the high-pressure hydraulic accumulator 31.
- the hydraulic circuit 100 of FIG. 1 actuates a "normally open” clutch 2 and a “normally closed” clutch 3 each having a hydraulic valve element 12 or 13.
- the hydraulic circuit 100 actuates two primary spur gear shifting groups 7 and 9 and the secondary shifting groups 4, 5, 6 and 8.
- Each of the clutches 2 and 3 is switched by a coupling valve element 12 and 13, respectively.
- the switching groups 4, 5, 6, 7, 8, 9 are each switched by two switching valve elements 14a / b, 15a / b, 16a / b, 17a / b, 18a / b, 19a / b.
- Each of the switching elements 12-19b has an actuation output which is acted upon by the high-pressure accumulator 31 for the desired deflection, for opening the clutch or for switching the desired switching state to the pressure. This admission takes place via the high-pressure line 3021, which splits between the valves without intermediate storage in the pressurizing lines 22-29b.
- the pressurization lines 22-29b are each connected to a pressurization port P of the valve element. 12 - 19b where high pressure is applied.
- the high pressure applied to the pressurizing port P is transmitted to the actuator flange A, and thus the corresponding component of the transmission is switched.
- the corresponding valve element 12 - 19b is switched so that the respective Aktuieranschiuss A with a tank port T of the corresponding valve element 12th - 19b is connected.
- the tank connection T of each of the valve elements 12-19b is connected via a separate tank line 402-409b to the low-pressure tank 40 of the hydraulic circuit 100 so that a simple pressure reduction at the transmission component connected via the corresponding valve element 12-19b (ie clutch or shifting group ).
- the clutches 2, 3 can be brought back into a closed state and the switching elements in a hydraulic power-free state, which allows a circuit in a different switching state.
- a hydraulic circuit 1 according to an embodiment of the invention is now shown for the same transmission.
- This is based on the idea to provide a possibility by means of which in the event of hydraulic and / or electrical failure of the hydraulic circuit when the high pressure level falls from the pressurization ports P of the valve elements 12-19b a compensation possibility can be provided by means of which at the output ports A the Valve elements 12 - 19b, the high pressure can be maintained despite the defect.
- a safety valve 50 is provided in the hydraulic circuit 1 between the high pressure pump 32 and the high pressure hydraulic accumulator 31 on the one hand and the coupling valve elements 12, 13 and the switching valve elements 14a - 19b on the other hand.
- the high pressure line 30 and a connecting line to the low pressure tank 40 is connected to this safety valve 50.
- a common pressurizing line 21 connected to the pressurizing lines 22-29b is connected and the collecting tank line 41 which in this embodiment is connected to the individual tank lines 42 and 43 of the two coupling valve elements 12 and 13 and to the individual tank lines 47a, 47b, 49a and 49b of the two primary switching groups 7 and 9 is connected.
- the secondary switching groups 4, 5, 6, and 8 are connected to the low pressure tank 40 via the conventional, separate tank lines 404, 405, 406, and 408 in this embodiment.
- the guidance of the drained hydraulic fluid via the collecting tank line 41 towards the safety valve 50 additionally opens up the possibility of pressurizing the collecting tank line 41 by means of a switching of the safety valve 50 with the high pressure applied to the high-pressure hydraulic accumulator 31 and thus applying this high pressure to the desired primary valve elements 12, 13, 17 and 19, at the same time, the secondary valve elements 14-16 and 18 are disconnected from the high pressure.
- the embodiment according to FIG. 3 is thus redundant, since not only the primary elements 2, 3, 7 and 9, which are necessary to achieve a safe driving condition, are included in the hydraulic circuit 1 with safety valve 50, but also the secondary elements 4, 5, 6 and 8, which in the case of failure of one of the primary elements 2, 3, 7 and 9 can replace them; thus this system is more fail-safe.
- the embodiment according to FIG. 2 is reduced to the primary elements 2, 3, 7 and 9 and thus enables a small-sized and therefore inexpensive to procure safety valve 50, and shorter hydraulic lines and a smaller high-pressure hydraulic accumulator 31, whereby effort during installation, acquisition costs as well as space can be saved ,
