  • Publication number: 20070049445
    Abstract: A drive train (1) of a hybrid vehicle having one internal combustion engine and one transmission (3), between the internal combustion engine and the transmission (3), at least one electric machine (7) with one stator (8) and one rotor (9) is situated wherein the rotor (9) can be connected by at least one friction clutch with a crankshaft (4) of the internal combustion engine and/or with an input shaft (16) of the transmission (3) and/or with a third shaft in which the rotor (9) is firmly connected with a rotor carrier (24) which supports component parts of the clutch on its radial inner side. The drive train is to be developed so that at least one wet-running clutch, actuatable by pressure medium, is situated so that it is very compactly designed and allows an active cooling of both the clutch discs and of the rotor carrier.

  • Publication number: 20060244325
    Abstract: A relatively abrasion-free seal for an electric motor that is inserted within the motor vehicle drive mechanism (6) to an electric motor rotor located within the free construction space (4) of the wet-running electric machine rotor (2) or oil-cooled gearshift element of a multiple disk clutch (5) with which the very highest possible degree of an oil free annular gap (3) between the rotor (2) and the stator (1) of an electric machine is provided essentially in that the face side of the annular gap (3) is designed to have a seal (9) which, at a high rate of revolutions by the rotor (2) and depending on the type of gap seal, has been built to seal without touching.

  • Publication number: 20060201277
    Abstract: A transmission device (3) for a vehicle with an electric machine (26) that is arranged in a housing (11) is described. The electric machine (26) can be placed in active connection with a rotating component (13, 28) that can be guided in the power flow of the transmission device such that a level of torque that can be generated by the electric machine (26) can be transmitted to the component (13, 28). At least one electric component (45; 45Y) that comprises power electronics for the electric machine (26) is arranged in a cross-sectional area inside the housing (11) that is perpendicular to the longitudinal axis of the electric machine (26) and is located directly adjacent to the electric machine (26).

  • Publication number: 20060205552
    Abstract: A transmission device (3) of a vehicle for distributing a driving torque of a transmission input shaft (13) to at least two transverse vehicle shafts (4; 4X; 4Y; 4Z; 5). Between the transmission input shaft (13) and a transmission output shaft (15) gear elements (16 to 25) are disposed in a housing (11) for the purpose of implementing different gear ratios. One of the vehicle axles (4; 4X; 4Y; 4Z) extends through an inner space (10) of the housing (11). In a cross-sectional area disposed perpendicular to the longitudinal axis of the transmission device (3), in which area the transverse vehicle shaft (4; 4X; 4Y; 4Z) that is guided through the housing (11) is disposed, at least part of an electrical device (45, 46), which is mounted to the housing side, and/or at least part of a temperature control unit (47), which is mounted to the housing side, are provided.

  • Publication number: 20060178239
    Abstract: An automatic transmission (1) is described, having a variator (5) that comprises at least two conical disk sets (2, 3), such that a wrap-around element (4) is guided via the conical disk sets (2, 3) for torque transmission with continuous variation of the transmission ratio. In this, the arrangement of the rotation axes of two conical disks of at least one conical disk set relative to one another can be varied.

  • Publication number: 20050215391
    Abstract: A cone ring transmission, especially for motor vehicles with a front, transverse drive is proposed, having two cones in opposed alignment to one another, rotating on two shafts, the cones being, namely a primary cone and a secondary cone, with an adjustment ring engaging both cones therebetween, the ring contacting one cone and circumferentially encompassing the other cone, with a mechanism to provide ratio adjustment for the adjustment ring, having an arrangement which binds the output drive shaft, i.e. the shaft of the secondary cone with a differential of the motor vehicle and with a start-up element, which binds one of the cones with the motor of the motor vehicle, whereby the torque from the output drive shaft is transmitted to a differential by way of a gear train.

  • Publication number: 20050176534
    Abstract: An automatic transmission (1) with a variator (5) and with at least two conical disk sets (2, 3) is described, such that a wrap-around element (4) is guided over the conical disk sets (2, 3) for torque transmission with continuously variable transmission ratio. In this, the arrangement of the rotation axes of two conical disks (3A, 3B) of a conical disk set (3) relative to one another can be changed, in that at least a first conical disk (3B) can be tilted relative to a second conical disk (3A) of the conical disk set (3).

  • Publication number: 20050164825
    Abstract: A transmission is proposed having two mutually opposed, rotationally symmetric rotating bodies arranged on two shafts, in particular a conical ring transmission with a primary cone and a secondary cone and with a ring which is engaged with both cones and surrounds one of the cones, in which shafts (5, 6) for the rotationally symmetric bodies or for the primary cone (2) and the secondary cone (3) enclose between them an angle not equal to zero.

  • Publication number: 20050056514
    Abstract: The invention concerns a clutch actuation system for a starting clutch (1) of a motor vehicle, with a hydraulic activated piston/cylinder combination (2), which possesses a pressure chamber (5) and a slidable activation piston (4) therein, with a pressure compensation compartment (6) for a dynamic pressure equalization, and which said pressure compensation compartment (6) can be filled with a fluid pressure medium, which, upon a rotation of the piston/cylinder combination (2) exercises a force which counters movement in a closure direction by the activation piston, and has a reset spring (7), which abuts against an inner wall of the pressure compensation compartment (6) and forcefully contacts a proximal surface of the activation piston (4).
