Definitions
- Electro-hydraulic system for the operation of multiple clutches and gear actuators with high-precision control of several manual transmission units simultaneously
- the present invention relates to a manual transmission according to the preamble of claim 1.
- DE 10 2006 038 446 AI a manual transmission with an electric motor-driven piston-cylinder unit is described, in which actuate one or two piston-cylinder units four gear actuator and two clutches.
- the piston-cylinder unit generates the pressure needed to adjust the gear actuators and clutches, with a pressure sensor measuring the pressure generated.
- DE 10 2006 038 446 A1 describes two possible embodiments for this purpose.
- clutches and gear shifter are adjusted over for actuation of so-called multiplex valves by means of the piston-cylinder unit.
- the pressure build-up and the pressure reduction via the piston-cylinder unit can take place.
- additional outlet valves are provided, via which the pressure in the individual consumers can be lowered regulated.
- the object of the invention is to improve the known from DE 10 2006 038 446 AI manual transmission on.
- the invention is advantageously characterized in that between each working space of a clutch actuator and a hydraulic main line in each case a valve is arranged, and both the pressure build-up and the pressure reduction takes place in the clutch actuators by adjusting the piston of a piston-cylinder unit, wherein the valve for the pressure change in Kuppiungssteiier is open and to keep pressure in Kuppiungssteiier, as well as to deactivate the clutch actuator while other transmission units of the respective hydraulic main line are operated, is closed.
- the valves by means of which the Kuppiungssteiier of the piston-cylinder units, which serve to adjust the Kuppiungssteiier, can advantageously be pure 2/2-way switching valves, since no proportional control takes place over them. Rather, the pressure build-up and -down takes place via the adjustment of the respective piston of the associated piston-cylinder unit.
- the volume of fluid required for switching the clutch actuator is advantageously displaced with the piston-cylinder unit via a volume control.
- a pressure volume characteristic curve can be used, in which the pressure change is stored during a corresponding path change of the piston of the piston-cylinder unit.
- a model can be used which simulates the corresponding relationships and thus required control variables and parameters can be determined, whereby a precise pressure gradient control is possible.
- expensive proportional valves can thus advantageously be dispensed with.
- the transmission according to the invention thus advantageously comes with a Win encoder on the drive of a piston-cylinder unit to meet the very high demands on a very precise pressure control (micro-slip control) of the clutches.
- micro-slip control pressure control
- pressure transmitters do not have the resolution like an angle transmitter of an electric motor.
- the usual pressure transmitters only achieve a resolution of approx. 0.5 bar.
- the use of an angle encoder brings a higher resolution by a factor of 10.
- a pressure transducer with corresponding high resolution is much expensive.
- the angle sensor may be e.g. a classic Hall sensor, which can be very cheap and also easily scanned.
- the gear selector of the gearbox according to the invention generally have in each case a first and a second work space separated by a piston, wherein the working spaces of the clutch plate via hydraulic connecting lines with the respective associated hydraulic main line are in communication.
- the first working spaces of the gear regulators are in each case connected by means of hydraulic connecting lines to the respective associated hydraulic main line, wherein the hydraulic connecting lines can each be shut off by means of a switching valve.
- the two working spaces limiting piston surfaces of the piston of the gear plate are formed differently large, wherein the larger piston surface limits the first working space.
- the second work spaces of the gear regulators are connected to the same main hydraulic line, with which the hydraulic supply lines in which the switching valve assigned to the gear selector are connected are also connected. ordered, connected.
- the second working spaces of the gear plate are connected by means of a respective hydraulic connecting line to the other main hydraulic line, with which the hydraulic supply line of the respective gear actuator, in which the associated switching valve is arranged, is not directly connected.
- a switching valve in particular a 2/2-way valve
- the associated valve 20a is opened and the valve 23a, which is arranged in the hydraulic line leading to the reservoir, closed.
- the two hydraulic main lines can be connected to one another via a hydraulic connecting line, wherein a switching valve for selectively opening or closing the hydraulic connecting line is arranged in the hydraulic connecting line.
- a switching valve for selectively opening or closing the hydraulic connecting line is arranged in the hydraulic connecting line.
- the control unit which controls the respective electromotive drive for adjusting at least one of the transmission units used as a manipulated variable for the control of the drive, the rotation angle ⁇ of the drive, the current flowing through the drive motor current i, the piston position s and / or the distance As of the piston of the Piston-cylinder unit, is so that the piston promotes a required hydraulic volume in or out of the respective a transmission unit.
- the gearbox units may have a position sensor or position sensor. Their signals can be advantageously used to control the drive and / or to calibrate the control and / or the simulation model.
- a pressure transducer If a pressure transducer is used, it will only be used for calibration or redundancy. If necessary, a very simple pressure transducer is sufficient only for calibration purposes in order to detect an assignment of the current flowing through the electric motor to the pressure, so that changes in the system, eg. B. efficiency change of the trapezoidal be considered. But this can also be done via a displacement sensor of the gear plate or clutches. The adjustment is crucial if z. B. a trapezoidal spindle is used in the electric motor, due to their properties, eg. B. it is made of plastic, high efficiency fluctuations in operation. However, the use of the trapezoidal spindle leads to significant cost savings, the additional effort for one or more calibration sensors is low.
- both hydraulic actuators can be adjusted in the form of the piston-cylinder units with only one pressure transducer.
- This can be z. B. via the connection line and the valve arranged therein, which connects the two hydraulic main lines together.
- the system can advantageously be simplified in such a way as to dispense with displacement sensors in the clutch and gear regulator.
- a very simple sensor eg. B. digital Hall switch to determine the discrete position of the gearshift (left, neutral, right) and clutches are used, with the clutch only a discrete position is needed.
- only one calibration sensor is used for both piston-cylinder units. Clutches and gear shifters are then exclusively via travel control of the engine with simultaneous use of the
- the transmission according to the invention can have more than two clutch plates. So it is easily possible that with the two piston-cylinder units three clutches and several gear actuators are operated. In the case of three clutch actuators or clutches, two or one clutch and one gear selector can be simultaneously displaced or switched at the same time.
- the third clutch actuator for example, via a supply line by means of a 3/3-way valve or at least two 2/2-way valves either from the two main hydraulic lines can be shut off or connected to one of the two main hydraulic lines.
- the third clutch actuator is connected by means of a valve only to a hydraulic main line. In the latter case, however, then the third clutch is no longer controlled separately from the other two clutch actuators.

- This advantageously has great effects on the costs, which are very relevant in particular in a system with two piston-cylinder units or hydraulic actuators.
- the use of a trapezoidal spindle is possible, which further cost savings are possible.
- At least one clutch is cooled by means of a cooling medium, wherein the cooling medium by means of the drive of a piston-cylinder unit or a separate drive, which in particular drives a pump, is promoted.
- a particularly favorable manual transmission is obtained when the drive drives the piston via a trapezoidal spindle.
- flow resistances in particular in the form of orifices in the hydraulic main lines, in particular in the coupling (s) with the gear actuators connecting portions may be arranged.
- Figure 2 shows a possible embodiment, where such an arrangement is advantageously used.
- a clutch can be controlled simultaneously via position or pressure and a gear position can be dealt with.
- the above-mentioned flow resistance in the form of a diaphragm prevents, for example, in an active control of the clutch Cl and a possible gear position to the left in the gear selector GS2, a rapid volume displacement in the piston of the hydraulic actuator 10a.
- the manual transmission according to the invention is advantageous in that either the Druckauf- and pressure reduction in at least two clutches simultaneously, temporally overlapping or successively by means of back and forth movements of the piston of the piston-cylinder units (10a, 10b) takes place or the Druckauf- or pressure reduction in a clutch with a piston-cylinder units and an adjustment of a gear adjuster simultaneously, temporally overlapping or successively by means of the other piston-cylinder units, wherein in the pressure change in a clutch, the respective associated valve is open ,

- FIG. 1a twin hydraulic actuator with ten or optionally eleven solenoid valves
- Figure lb twin hydraulic actuator with three clutches
- Figure 2 Twin hydraulic actuator with six or optionally seven solenoid valves.
- the figure la shows an embodiment of the actuating unit according to the invention in the execution of a multi-clutch transmission.
- the actuating unit consists of the partial transmission 1, the partial transmission 2 and the pressure supply unit 3.
- the pressure supply unit consists of the two piston-cylinder units or hydraulic actuators 10a and 10b.
- the transmission is configured so that in a partial transmission 1, the odd gears, and in the other partial transmission, the even gears and decline are arranged.
- Both partial transmissions and both hydraulic actuators are constructed identically in principle, so that in the following only the partial transmission 1 and hydraulic actuator 1 are described in more detail.
- its reference numerals are provided with the index a and c.
- the description also applies to the partial transmission 2 and hydraulic actuator 2 with the corresponding change of the indices from a to b, and c to d.
- the idea according to the invention can also be extended to transmissions with different numbers of hydraulic actuators. More or less clutches C1, C2 or gear plates 7a-d can be connected as shown here.
- the clutch Cl In the partial transmission 1 actuates the actuating piston 6a of the clutch actuator 4a, the clutch Cl, not shown.
- the stroke is detected via the displacement sensor 5a.
- the clutch Cl, not shown, is preferably designed so that it is opened in the unactuated case of the clutch spring.
- the partial transmission 1 consists of the gear actuators 7a and 7c. Again, only the function of the gear actuator 7a is described. Due to the corresponding change of indices, the description also applies to the gear plate 7c, or the gear plate 7b and 7d of the partial transmission. 2
- the gear actuator piston 8a actuated via the gear shift fork, not shown, the respective gears of the dual-clutch transmission, not shown.
- the displacement sensor 9a detects the stroke of the gear actuator piston 8a.
- the gear actuator 7a is designed as a double-acting piston 8a.
- the two gear actuator chambers 21a and 22a have different sized hydraulically effective surfaces. Both gear actuator chambers are connected to the pressure line 18a constituting the first hydraulic main pipe, and the left gear actuator chamber 21a can be separated from the pressure pipe 18a by the gear actuator valve 20a. In addition, the left gear actuator chamber 21a can be connected to the reservoir 25 by correspondingly switching the gear regulator outlet valve 23a via the hydraulic line 24a.
- the hydraulic actuator 1 is composed of the drive motor 11a, a transmission 13a, and a hydraulic piston 14a having the hydraulic chamber 40a.
- the hydraulic chamber 40a can draw hydraulic fluid from the reservoir 25 via the check valve 15a and the hydraulic line 16a by closing the switching valves 19a, 20a, 20c and 26 and returning the piston 14a.
- the piston 14a moves forward, the hydraulic fluid in the chamber 40a is displaced, whereby pressure is produced in the pressure line 18a. This pressure can be detected by the optional pressure transducer 17a.
- the motor angle sensor detects the rotor position and can thus detect the piston stroke via the known gear ratio.
- the engine torque and thus indirectly the pressure in the hydraulic chamber 40a can be measured via a corresponding current sensor (not shown) in the electronics.
- the clutches are often operated in so-called micro-slip. This is done especially with so-called wet couplings but also with dry couplings. As a result, it is necessary that the clutch actuation must be permanently readjusted.
- the inventive use of two hydraulic actuators it is possible that a hydraulic actuator permanently controls the pressure in the active clutch and the other hydraulic actuator simultaneously and independently done the gear position of the inactive subtransmission.
- the two hydraulic lines 18a and 18b can be connected.
- the hydraulic actuator of the closing clutch has to apply less power and thus can be made smaller, whereby costs can be saved.
- all the actuations of the hydraulic actuators are effected by the position and speed of the master cylinders 14a and 14b, or the pressure in the pressure lines 18a and 18b.
- the valves do not have to fulfill a pressure control task, but represent a pure hydraulic connection between the respective pressure chambers.
- valves shown can thus be represented as purely digital switching 2/2 way valves. These can be designed as so-called ball seat valves. These valves are much cheaper than proportional valves and have a much lower leakage in the closed state. The electronics required for switching is also advantageously much simpler. Also, the drive logic of these valves is simpler since no thermal models, etc. are required. The ball seat valves are also smaller.
- Ball seat valves in 2/2 way versions can be designed to be normally open or normally closed.
- Fig. Lb shows the extension of the actuator described in Figure la actuator to a transmission with other hydraulic actuators, here beispielwese a 3. couplings.
- Such transmissions are used, for example, in hybrid vehicles.
- the additional coupling 41 can be connected via the additional valves 42a and 42b to the pressure lines 18a and 18b.
- this clutch can be actuated via the hydraulic actuator 1 or the hydraulic actuator 2.
- the coupling can be controlled via position or pressure.
- the coupling can be designed to be open or closed when not in operation.
- it is possible a clutch with leakage z. B. to operate with hydraulic rotary feedthrough.
- FIG. 2 shows a further possible embodiment of the actuating unit according to the invention in the form of a multi-clutch transmission.
- the hydraulic actuator 10a directly drives the clutch actuator 4a.
- the pressure in the pressure line 18a thus also lies in the right gear actuator chamber 22b of the gear plate 7b. Since the valve 20b is closed, the gear actuator piston 8b does not move. Nevertheless, pressure builds up in the left gear actuator chamber 21b. Since the left gear actuator chamber 21b has a larger hydraulically active area than the right gear actuator chamber 22b, the pressure in the left gear actuator chamber is smaller in accordance with the area ratio of the two gear selector chambers. This in the left gear actuator chamber 21b adjusting pressure is now controlled by the hydraulic actuator 10b. As a controlled variable, the pressure transmitter 17b can be used for this purpose.
- the pressure can also be regulated with sufficient accuracy via the motor current.
- the gear regulator inlet valve 20b is opened. Since a balance of forces acts on the gear actuator piston 8b, this initially remains in the middle position.
- the hydraulic actuator 10b starts to supply hydraulic fluid to the left-hand gear actuator chamber 21b.
- the master cylinder 14a is moved backward, so that the pressure in the shifter 4a remains constant, but at the same time fluid is taken out of the right shifter chamber 22b. It is also possible during this process to modulate the pressure or position of the clutch actuator.
- An optional hydraulic damping element 27a can be used to reduce the influence of the pressure in the gear plate 4a by a dynamic gear shift operation.
- the sequence of the switching operation of the gear actuator 7b in the left end position is almost identical. Only the direction of movement of the two hydraulic actuators changes, so that the hydraulic actuator 10b withdraws fluid from the left hydraulic actuator chamber 21b and the hydraulic actuator 10a delivers fluid into the right hydraulic actuator chamber 22b.
- the sequence for switching operations of the gear shifter 7a-9d is analogous to the case described here by way of example. Only the corresponding gear actuator inlet valve 20a-20d is opened.
- the control of the gear actuator piston 8a-8d is selected so that the pressure of the active clutch actuator 4a or 4b acts on the right gear actuator chamber 22a-22d.
- the pressure which must be established in the each to be controlled left gear actuator chamber 21a-21d each lower than the pressure in the active gear actuator 4a or 4b.
- the hydraulic actuators 10a-10b can be designed for the maximum required pressure for the clutch actuation and need not provide even higher pressures for the gear position.
- no higher engine torque can be provided.
- By the described embodiment of the actuating unit it is thus possible to reduce the number of switching valves required and still have the full degrees of freedom in the simultaneous control of the clutch and gear position.
- the power requirements on the hydraulic actuator 10a and 10b thereby do not increase compared with the embodiment in FIG. 1a.
- a connecting valve 26 can also be used here with the advantages already described.
- the connection valve can be used to discharge hydraulic fluid from the hydraulic actuators 10a or 10b into the reservoir 25.
- the pressure chamber 40b is hydraulically via the line via a beak not shown in detail 16b connected to the reservoir. If now the master cylinder 14a is advanced or retracted with the connecting valve 26 open, the volume of the hydraulic fluid in the pressure chamber 40a can be actively reduced or increased. This allows an additional degree of freedom in the control. Since this degree of freedom is not necessarily required, or only in special situations, the use of the connecting valve is not mandatory.
