  • 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: 20200116208
    Abstract: An inner disc carrier (LT) for a wet-type friction clutch (K0) may have a driving toothing including ridges (S, SX) and grooves (N) for the form-locking accommodation of discs (L) of the friction clutch (K0). Each of a first group of the ridges (S) has a first opening (A1) produced in a chip-less shaping process and a section (ST) extending radially inwardly at the first opening (A1) and created during production of the first opening (A1). Hydraulic fluid supplied radially from inside the inner disc carrier (LT) from a first axial position is guided through the first openings (A1) to the discs (L). Hydraulic fluid supplied radially from inside the inner disk carrier (LT) from a second axial position is guided past the discs (L). The sections (ST) of the ridges (S) act as a damming contour for hydraulic fluid supplied radially from the second axial position.

  • Publication number: 20200031292
    Abstract: A noise insulation element (14) for the bulkhead (12) of a vehicle body (10) is provided with a mass-spring element (20) which has a plastic support layer (22) as the heavy layer with a front side facing away from the bulkhead (12) when the mass-spring element (20) is installed and with a rear side facing towards the bulk-head (12), and a noise damping layer (24) made from a noise insulating material connected to the rear wall as the spring layer. The support layer (22) is provided on its rear side with an integrally designed hollow fixing projection (16) which is formed on an edge recess with a recess edge which recess is open towards an outer limiting edge section (28) of the support layer (22) and a side wall (30) projecting from the rear side of the support layer (22) and extending along the recess edge.

  • Publication number: 20190383381
    Abstract: A transmission for a motor vehicle has an input shaft, an output shaft, a ratio-changing device by which different transmission ratios are made available, a housing, a hub connected to a torsional damper, and a separating clutch including a first clutch half and a second clutch half. The hub is connected to the first clutch half. The input shaft is rotationally fixed to the second clutch half and extends axially into the ratio-changing device. A first axial end of the input shaft is directly or indirectly supported on the housing in a radial direction via a first bearing. A second axial end of the input shaft is supported directly on the hub in the radial direction via a second bearing. Additionally, the hub is directly supported on a bearing shield in the radial direction via a third bearing, the bearing shield being rotationally fixed to the housing.

  • Patent number: 10240670
    Abstract: A planetary transmission includes a planetary gear set (1), another planetary gear set (2), a fluid line (3) through which fluid is flowable to the planetary gear set (1) and to the other planetary gear set (2), and a fluid collecting device (4) which is in fluid communication with the fluid line (3). The fluid collecting device (4) is connected in a rotationally fixed manner to the planetary gear set (1). The fluid collecting device (4) is configured for dividing the fluid from the fluid line (3) which has flowed into the fluid collecting device (4) into a fluid part which is flowable to the planetary gear set (1) and another fluid part which is flowable to the other planetary gear set (2).
