  • Patent number: 10889316
    Abstract: A steering gear apparatus includes a rack shaft, a pinion shaft, and a housing. The rack shaft has rack teeth and moves in an axial direction to steer front wheels. The pinion shaft has pinion teeth and rotates in accordance with steering operation of a steering wheel. The housing supports the rack shaft and the pinion shaft, and houses a meshing area between the rack teeth and the pinion teeth. When the steering wheel is in its neutral position, the pinion teeth mesh with the rack teeth at a rotational position of the pinion shaft that minimizes torque required to move the rack shaft in the axial direction during one rotation of the pinion shaft.

  • Patent number: 10823284
    Abstract: Provided is a power transmission control device capable of reliably performing engagement between an engagement member and a target engagement member, by operating the engagement member to slide by an actuator having an elastic member deformed by transmitting a load received by the engagement member. An actuator has an elastic member, and a control unit calculates the differential rotation between an engagement member and target engagement members on the basis of the detected rotation speeds of a first rotation shaft and a second rotation shaft, and makes differential rotation coincide with a predetermined differential rotation by adjusting the rotation speed of power sources. After the differential rotation coincides with the predetermined differential rotation, in establishing the engagement, the predetermined differential rotation sets the differential rotation on the basis of a natural frequency generated in conjunction between the actuator and the engagement member by the elastic member.

  • Patent number: 10808833
    Abstract: In a shift device, when a switch is operated, a moving portion, a first lock plate, a second lock plate and a third lock plate are moved toward a vehicle front side, and placement of the first lock plate, the second lock plate and the third lock plate at a return path is cancelled. Therefore, if the switch is operated when a lever is placed at other than a “P” position, due to a guide pin being moved along the return path toward an upper side by urging force of a return spring, the guide pin is returned to a vehicle front side end of a first lateral path, and the lever is returned to the “P” position. Due thereto, the lever can easily return to the “P” position from other than the “P” position.
