  • Patent number: 10300905
    Abstract: An electric vehicle drive system includes an electric motor, first and second planetary gear sets, including sun gear, carrier and ring gear members, first and second output shafts, and a housing. The members of the first planetary gear set are connected with the electric motor, the first output shaft, and a member of the second planetary gear set. The members of the second planetary gear set are connected with the first planetary gear set, the housing, and the second output shaft. The first planetary gear set provides differential reduction and the second planetary gear set provides reversal and reduction. Optional clutches can provide the function of a limited slip differential and distribute torque preferentially to one output shaft or the other.
    Type: Grant

  • Patent number: 9610902
    Abstract: An assembly for supporting a first vehicle component manages loading of the first vehicle component under applied forces by enabling a slip joint connection between the first vehicle component and a supportive mounting bracket. More specifically, the assembly includes a mounting bracket that has a slot. A plate is fit within the slot. A stud extends from the plate. The stud is configured to extend through an opening in the first vehicle component when the first vehicle component is mounted to the mounting bracket to capture the mounting bracket between the plate and the first vehicle component at the stud. The mounting bracket and the plate are cooperatively configured as a slip joint. A method of assembly is also provided.
