  • Patent number: 11906034
    Abstract: In a drive apparatus, a ring gear of a differential device is rotatable about a third axis in a direction opposite to a counter gear of a deceleration device. The inner surface of the gear housing accommodating the deceleration device, the differential device, and the reservoir capable of storing a fluid includes first and second curved surfaces disposed in the +X direction with respect to the third and second axes, respectively. At least a part of the first curved surface faces the radially outer end portion of the ring gear in the radial direction and extends in the circumferential direction. At least a part of the second curved surface faces the radially outer end portion of the counter gear in the radial direction and extends in the circumferential direction. The position of the reservoir in the Y-axis direction overlaps the first curved surface and the second curved surface.

  • Patent number: 11906005
    Abstract: A coupling and control assembly including a non-contact, linear inductive position sensor is provided. The assembly includes a coupling housing and a stator structure disposed within the coupling housing and including a stator housing. A translator structure is coupled to a coupling member of the assembly to rotate therewith about a rotational axis. The sensor is mounted on one of the housings. The translator structure includes a coupler element made of an electrically conductive material. The sensor is configured to create a magnetic field to induce eddy currents in the electrically conductive material. Movement of the coupler element changes a magnetic field caused by the eddy currents. The sensor provides a position feedback signal for vehicle transmission control. The signal is correlated with the linear position of the translator structure along the rotational axis.

  • Patent number: 11885405
    Abstract: A housing for a plastic gearbox and associated plastic gearbox and a robot. The housing includes a body including an inner engaging portion circumferentially arranged on an inner surface of the body, the inner engaging portion adapted to be engaged with a transmission assembly of the plastic gearbox; and an adjusting mechanism arranged around the body and operable to squeeze the body inwardly to reduce an inner diameter of the body. By using the adjusting mechanism to squeeze the body of the housing inwardly, the fit error between the inner engaging portion and the transmission assembly can be compensated in an efficient way. Furthermore, the adjusting mechanism is a part of the housing and thus the body of the housing which is made of plastic does not need to be too thick, which makes injection molding easier and manufacturing precision improved.
