Definitions
- the present invention relates to the field of transmissions for motor vehicles. It more particularly relates to an actuating assembly intended to act on a wet type clutch, that is to say whose friction discs are immersed in the oil.
- Double clutches of this type comprise two sets of friction discs each controlled by a diaphragm cooperating with a clutch abutment.
- Each clutch abutment is hydraulically actuated: it is oil under pressure which sets each of the stops in motion.
- Such a clutch is described in the document EP 1 610 021 relating to a double wet clutch whose clutch stops are moved by a fork which is controlled by an electric motor.
- the object of the invention is to improve this type of clutch by proposing an actuator adapted to wet clutches whose positioning and lubrication are optimized.
- the invention relates to an actuating assembly for wet clutch of a motor vehicle, said actuating assembly comprising at least one motor, at least in part a movable member adapted to act on said wet clutch to engage or disengage, at least one transmission device between said motor and said movable member, and a reservoir adapted to form at least partly oil sump for said wet clutch, said actuating assembly being characterized in that at least the transmission device is placed inside this reservoir, the reservoir comprising fastening means for cooperating with a main casing surrounding said wet clutch and having at least one opening in its lower part, so that the reservoir closes said opening and forms a secondary casing in which the oil is adapted to flow by gravity.
- the contact surfaces of the discs which transmit the power between the motor shaft and the output shaft of the gearbox are lubricated by means of an oil sump in the lower part of the clutch, the oil pan is located below the discs to recover the oil.
- the invention takes advantage of this configuration by providing the actuator assembly with a reservoir providing, at least in part, the function of oil sump for the clutch. The overall size of the actuating assembly is thus reduced and the lubrication of the elements in this reservoir is advantageously ensured by the oil which already lubricates the wet clutch.
- the tank comprises at least one joint plane for cooperating with at least one joint plane of said wet clutch
- the movable member is also disposed in the reservoir
- the reservoir comprises a wall on which the motor is mounted; - The motor is disposed outside the tank, the transmission device being connected to the motor via an orifice in said wall; said orifice being preferably sealed;
- the actuating assembly further comprises means for sealing said orifice;
- the movable member has at its free end at least one swivel member adapted to control at least one fork of said wet clutch;
- the transmission device comprises means for transforming the rotary movement of the motor in linear movement of the movable member
- the transmission device comprises a compensating member
- the action unit also comprises a second motor associated with a second transmission device and a second movable member, this second transmission device being disposed in the reservoir and this second movable member preferably being disposed in the reservoir, the actuating assembly being thus adapted to the control of a double wet clutch;
- the tank has in its interior a magnet
- the invention aims at a double wet clutch comprising a main casing surrounding said double wet clutch and having at least one opening in its lower part, said main casing being associated with an actuating assembly as described above. , so that the tank closes said opening and forms a secondary casing in which the oil is adapted to flow by gravity.
- the clutch and the wet double clutch above have the same advantages as those described above with respect to the actuating assembly.
- FIG. 2 shows a perspective view from above of an embodiment of the actuating assembly according to the invention.
- FIG. 1 is a schematic and simplified representation of a transmission system comprising a gearbox 2, a clutch 3 disposed in a main clutch casing 1, and a flywheel 4 mounted on a transmission shaft 5.
- the transmission shaft 5 connects the motor shaft to the output shaft of the gearbox 2, these two shafts are not shown.
- the control 6 of the clutch comprises a fork 7 and an actuating assembly 8 according to the invention.
- This actuating assembly 8 is adapted to move horizontally (with reference to FIG. 1) the free end of the fork 7 which causes its pivoting and the control of the diaphragm (not shown) of the clutch in order to carry out the maneuver. 'clutch or clutch,
- the actuating assembly 8 here comprises an electric motor 11 associated with a gearbox 12, a transmission device 10 and at least partly a movable member 15.
- the motor 11 can be used alone, without the gearbox 12, if its features allow it.
- the term "motor” in this patent application refers to both a single motor and a motor 11 and gear unit 12.
- the motor thus formed here of a motor 11 and a gear 12, is connected to the transmission device 10 which is adapted to transform the rotary movement of the gear 12 into horizontal linear movement allowing the moving member 15 to be moved. at the fork 7 whose pivoting is thus controlled.
- the transmission device 10 makes it possible to ensure this transformation of movement by known means such as a screw-nut system or a crank-handle system.
- the transmission device 10 may also include a spring or hydraulic compensation system. These systems are known in the art and allow energy to be stored during the release of the diaphragm of the clutch and then facilitate the compression of the diaphragm by releasing this energy.
- the actuating assembly 8 further comprises a reservoir 9 having a wall 13 on which the motor (11, 12) and the transmission device 10 are mounted.
- the actuating assembly 8 is mounted on the main casing 1 of the clutch 3 only via the reservoir 9 by means of fixing means, for example consisting of screws (not shown) adapted to be inserted into orifices (not shown).
- the reservoir 9 partially replaces the main housing 1 of the clutch, and this in the part commonly called "oil sump" that is to say the hollow part in which the oil used for the Lubrication of the wet clutch 3 flows by gravity and can stagnate when the vehicle is stationary. A certain volume of oil is therefore always present in the tank 9, under the normal conditions of use of the vehicle.
- Some members of the actuating assembly thus bathe in the oil of the clutch 3, that is to say, here, the transmission device 10 and at least partly the movable member 15.
- Figure 2 shows an actuating assembly 8 according to one embodiment of the invention. It is an actuation assembly adapted to a double wet clutch and which is here shown alone.
- This actuating assembly 8 comprises two motors 11 A, 11 B associated with two reducers 12A, 12B, two transmission devices 1OA, 1 OB connecting two rods 14A 1 14B two movable members 15A 1 15B.
- This dual arrangement allows the movable members 15A, 15B to control the two forks and / or the two stops that comprises a double wet clutch.
- the movable members 15A, 15B here have a hemispherical shape which makes them rotulants adapted to form a ball joint with the forks for which they are provided.
- the motor assemblies 11A 1 11 B - reducer 12A, 12B are mounted on the wall 13, to outside the tank 9 while the devices of transmission 10A, 10B are mounted on the same wall 13 but inside the tank 9.
- An orifice (not visible in the figures) connects each motor to the corresponding transmission device.
- a seal may be provided to seal the reservoir 9 at these ports.
- the reservoir 9 comprises a joint plane 16 traversed by fixing means constituted here by holes 17 provided for the passage of screws (not shown).
- the actuating assembly 8 can thus be fixed on the main casing 1, by closing an opening of this main casing 1 in a sealed manner thanks to the joint plane adapted to cooperate with a corresponding joint plane on the main casing 1, with possible interposition of a seal.
- the actuating assembly can be fixed to the main casing 1 exclusively by these fastening means 17 associated with the joint plane 16.
- a magnet 18 is placed in the reservoir 9 to attract the filings or other ferrous waste possibly present in the oil and thus keep them away from the elements of the actuating assembly which are immersed in the oil.
