  • Patent number: 12638070
    Abstract: The present disclosure relates to a guide assembly, comprising: an outer guide member; an inner guide member at least partially enclosed by the outer guide member, the outer guide member and the inner guide member delimiting a space therebetween; an elastic member disposed in the space, enclosing the inner guide member and being compressible along an axial direction; a support member; and an actuation member configured to axially compress the elastic member against the support member. The inner guide member comprises an axially extending guiding surface facing the elastic member for restricting movement of the elastic member in a radial direction perpendicular to the axial direction. A length of an axial overlap between the guiding surface of the inner guide member and the elastic member is at least two thirds of an axial length of the elastic member.

  • Patent number: 12296830
    Abstract: Systems and methods for a drive axle. The drive axle system, in one example, includes a displacement sensor coupled to a pinion input flange and configured to generate axial displacement data corresponding to the pinion input flange, where the pinion input flange is directly coupled to an angled pinion gear. The drive axle system further includes a controller configured to determine a torque at the pinion input flange based on the axial displacement data.
