  • Dual transmission with triangularly arranged gear center positions
    Patent number: 11865908
    Abstract: A dual transmission with input shafts, output shafts, a transmission case and two separate single transmissions arranged in the transmission case is described. Each single transmission is a two-stage spur gear transmission with three positions for gear centers. A first position is occupied by an input shaft and a second position by an output shaft. A third position is for a middle stationary axle fixed to the transmission case. The three positions define a triangular arrangement having a first side defined by a distance between the first position and the second position, a second side defined by a distance between the first position and the third position, and a third side defined by a distance between the second position and the third position. The second side and the third side form respective angles with the first side. At least one of these angles has a value ranging between 5° and 70°.

  • GEARBOX, IN PARTICULAR A TWIN GEARBOX, AND BEARING BRACKET WITH AN ADVANTAGEOUS OIL LUBRICATION BY MEANS OF A MULTI-CHAMBER SYSTEM, AS WELL AS METHOD SUITABLE FOR LUBRICATING SUCH A GEARBOX
    Publication number: 20220260153
    Abstract: A twin transmission of a dual electric machine powertrain is presented. The twin transmission has a gear stage, a sump, a multi-chamber system adjacent to the gear stage, and a delay arrangement with a hydraulic flow restrictor. The multi-chamber system provides a flow path that continuously delivers a lubricant into the sump through the hydraulic flow restrictor.
