  • Patent number: 11092202
    Abstract: A control apparatus for a vehicle drive-force transmitting apparatus which defines a first drive-force transmitting path provided with a first clutch and a two-way clutch and a second drive-force transmitting path provided with a continuously variable transmission and a second clutch. The control apparatus switches the two-way clutch from its lock mode to its one-way mode, when the second drive-force transmitting path is to be established in place of the first drive-force transmitting path. The drive-force transmitting apparatus includes a hydraulic actuator configured to control switching of the two-way clutch between the lock mode and the one-way mode. When a request for establishing the second drive-force transmitting path in place of the first drive-force transmitting path is made during forward running of the vehicle with the two-way clutch being in the lock mode, the control apparatus executes a dither control for fluctuating a hydraulic pressure applied to the hydraulic actuator.

  • Patent number: 11047458
    Abstract: A compliant crank slider with adjustable constant-force output. Constant-force mechanisms (CFM) are used to maintain a constant output reaction force throughout a large range of compressive motion. The invention improves on existing CFM by introducing a second degree of freedom that adjusts the mechanism's output without changing its kinematic structure. This second degree of freedom is the rotation of a compliant beam about its longitudinal axis as it is constrained to the initial plane of bending. In an embodiment, the second degree of freedom is the rotation of both a first compliant beam and a second compliant beam. The resulting change in the constant force mechanism allows for adjustment to a specifiable range of constant-force outputs.

  • Patent number: 11047457
    Abstract: Rack-and-pinion sliding support mechanisms and mechanical elements thereof. One or more shafts are coupled to pinions configured to engage with one or more racks and configured to be driven by one or more motors. The rack and pinion are configured to provide vertical and horizontal displacement to reduce premature component wear leading to poor gear mesh caused to by forces on the mechanism during use. Motor assembly in such support mechanism is modified—as compared to current industrial versions—to prevent the destruction of motor-assembly housing by torques generated by the one or more motors and transferred to the pinions, thereby reducing motor failures.
