  • Patent number: 11708888
    Abstract: A shaft (W) for a motor vehicle transmission (G) includes four axial bore holes (B1, B2, B3, B4) for conducting fluid within the shaft (W). A central axis of each of the four bore holes (B1, B2, B3, B4) is spaced apart from an axis of rotation (WA) of the shaft (W). A radial distance (r1) between the central axis of at least two of the four bore holes (B1, B2, B3, B4) and the axis of rotation (WA) differs from a radial distance (r2) between the central axis of one of the remaining bore holes and the axis of rotation (WA). A transmission (G) for a motor vehicle with a shaft (W) is also provided.

  • Patent number: 11359715
    Abstract: A shaft (W) for a motor vehicle transmission (G) may have axial bore holes positioned within the shaft and configured to guide fluid within the shaft. The shaft may have first, second, and third axial sections (W1, W2, W3), the second axial section being axially between the first and third axial sections. Fluid enters the axial bore holes in the second axial section and exits the axial bore holes in the first and third axial sections. One of the axial bore holes (B2; B1, B1a) is arranged, at least partially, in the first axial section and is radially spaced from an axis of rotation (WA) of the shaft. Another of the axial bore holes (B1RS; B_SE5, B3a) is arranged, at least partially, in the third axial section. The one of the axial bore holes (B2; B1, B1a) is coaxial with the other of the axial bore holes (B1RS; B_SE5, B3a).

  • Publication number: 20200247229
    Abstract: A hybrid drive module (1) for a motor vehicle includes a housing (GG), a torque converter (TC), and an electric machine with a rotor (R) and a stator (S). The rotor (R) is arranged on a rotor carrier (RT), which is fixedly connected to a hub (N). The hub (N) is rotatably supported via at least one first bearing (L1) and is supported in radial and axial directions against a bearing shield (LS). The hub (N) is rotationally fixed to a converter housing (TCH) of the torque converter (TC) via a rivet joint (RI) or a screw connection. A drive train for a motor vehicle including such a hybrid drive module (1) is also provided.

  • Publication number: 20190039447
    Abstract: A transmission (G) for a motor vehicle includes an input shaft (GW1), an output shaft (GW2), a differential gear (AG), an interface (IF) to a transmission-external drive unit, an electric machine (EM) with a rotationally fixed stator (S) and a rotary rotor (R), a plurality of planetary gear sets (PS, PV), and a plurality of shift elements (A, B, C, D, E). The electric machine (EM) is arranged at an axial end of the transmission (G) which is positioned opposite the interface (IF) to the transmission-external drive unit. An area (X) directly adjacent to the differential gear (AG) is configured for accommodating a joint (GL) of a motor vehicle side shaft (DS) and is arranged completely or at least in part in an installation space radially outside the electric machine (EM).

  • Patent number: 8556010
    Abstract: A drive unit includes an internal combustion engine with a driven shaft, a transmission with an input shaft, and an electric machine arranged between the internal combustion engine and the transmission and comprising a stator and a rotor which can be coupled at least indirectly to the driven shaft of the internal combustion engine and to the transmission input shaft in order to transmit torque. The drive unit includes a clutch arranged in the torque transmission path between the internal combustion engine and the transmission. To facilitate the decoupling of rotational irregularities occurring in the drivetrain of the hybrid vehicle the drive unit has a first torsional damper and a second torsional damper, and at least the rotor of the electric machine is arranged within a torque transmission path formed between the torsional dampers.

  • Patent number: 3934366
    Abstract: A system for producing a variety of static multicolor light displays includes a plurality of different colored translucent image-producing elements. A light source is positioned to direct light through the image-producing elements and onto a display surface. The image-producing elements are three-dimensional and positionable to produce a variety of different static visual and aesthetic displays. The image producing elements are detachably held in position, against a base which may comprise all or part of the display surface. To provide the capability of vertically suspending the system, like a painting, the elements may be held in position by magnetic force or means such as pegs as mechanical interlocks or adhesives. Such means, or others, such as weights, may be employed for systems positioned horizontally. The light source may be attached to the base to provide a self-contained unit.
