Abstract: The inventive double-clutch transmission element for a hybrid pull chain of a motor vehicle comprises a motion input shaft (37), a motion output shaft (39), an electrical machine (31) comprising a stator (61) and a rotor (63), a first clutch (33) providing a connection between the input shaft (37) and an intermediate member (73), and a second clutch (35) providing a connection between the intermediate member (73) and the output shaft (39), the intermediate member (73) being coupled in rotation to the rotor (63). A casing comprising a first half-shell (51) rotatably supporting the input shaft (37) and a second half-shell (52) rotatably supporting the output shaft (39) defines a housing in which the two clutches (33, 35) and the electrical machine (31) are mounted in a co-axial manner. The invention also relates to a motor vehicle equipped with such transmission element and to a method of mounting same.

Abstract: The invention relates to a transmission module (10) for an engine-transmission unit, said module comprising an input shaft (11) for connecting to a heat engine, an output shaft (12) for connecting to a gearbox, and a clutch (30) connecting said two shafts. The inventive module also comprises: an independent casing (16) comprising a first half-shell (17) and a second half-shell (18), said two half-shells forming a sealed receiving element (22) containing the clutch (30) which is naturally in the engaged position; a mechanical element (35) for maintaining the clutch (30) in said engaged position by means of a piston in the form of a disk; a hydraulic control circuit (40, 41) for acting directly on the piston against the mechanical element, in the disengaged position of said clutch (30); and a hydraulic circuit (50, 52, 53, 55, 56) for lubricating and cooling the clutch. The invention can be applied to an engine-transmission unit for motor vehicles.

Abstract: The invention concerns an element comprising an electrical machine (31), two wet clutches (33, 35), a cooling fluid circuit, including a chamber (53) for cooling the clutches (33, 35), a fluid tank (251), and a pump (255). The pump (225) is connected to a recycling channel (259), the cooling circuit comprising selecting means (257) arranged upstream of the pump (255), such that said pump is capable of selectively feeding said chamber (53) from the tank (251) and from the recycling channel (259) based on the temperature of the fluid passing through the selecting means (257). The invention also concerns an associated cooling and/or lubricating, and clutch control method, as well as a motor vehicle equipped with such a transmission document.

Abstract: The invention concerns an assembly comprising a hydraulic system (401, 501) and a transmission element including an input shaft, an output shaft, an electrical machine including a rotor, a first clutch between the input shaft and the rotor, and a second clutch between the rotor and the output shaft, said clutches being of the wet type, said transmission element further comprising a lubricating circuit (301), and means for controlling said clutches, which include a control circuit (302) comprising a pressure chamber (201, 202) for each clutch. One of said circuits (301, 303) is connected to said hydraulic system (401, 501). The invention also concerns a motor vehicle equipped with such a functional assembly.

Abstract: The invention relates to a double-clutch transmission element for a hybrid pull chain of a motor vehicle, a method of mounting same and a motor vehicle equipped with one such element. The inventive element (25) consists of a motion input shaft (37), a motion output shaft (39), an electrical machine (31) comprising a stator (61) and a rotor (63), a first clutch (33) providing a connection between the input shaft (37) and an intermediate member (73), and a second clutch (35) providing a connection between the intermediate member (73) and the output shaft (39), said intermediate member (73) being coupled in rotation to the rotor (63). The transmission element is also equipped with a casing comprising a first half-shell (51) which supports the input shaft (37) in rotation and a second half-shell (52) which supports the output shaft (39) in rotation, said two half-shells (51, 52) defining a housing in which the two clutches (33, 35) and the electrical machine (31) are mounted in a co-axial manner.
