The device also at least partially recovers, in the form of electrical energy, the kinetic energy lost by the primary shaft and transmits the electrical energy to an energy storage device.

  • Patent number: 10731750
    Abstract: A rotary shifter having a housing with a bezel cover. A knob is rotatably secured to the housing and is selectively rotatable between each of Reverse Neutral and Drive positions. A push button is configured within the rotary knob and, upon depressing, communicates with a sensor and switch within the housing for establishing the Park position. In a related variant, a Sport position lock ring is secured to a stem of the knob in a normally biasing engagement with an underside of the bezel cover to prevent shifting to the Sport position, the knob being vertically depressed in a counter direction to the bias in order to vertically unseat the lock ring and to permit subsequent rotation to the Sport position. A Sport position spring can also be provided supporting an underside of the plunger housing locker forming a portion of the plunger housing subassembly.

    Abstract: The present disclosure discloses a sensing system for sensing a position of a gear shaft. The present disclosure may implement determination of whether the gear shaft is at a reverse gear position, a forward gear position or a neutral gear position by: partitioning a magnet into a first length region magnet and a second length region magnet, wherein the first length region magnet and the second length region magnet have different magnetic field directions, sensing and generating an inductive electrical signal reflecting motions of the first length region magnet and the second length region magnet; storing, by a memory unit, a first type reference signal for the first length region magnet and a second type reference signal for the second length region magnet, which are sensed by simulation; and comparing, by a processing unit, the inductive electric signal against the first type reference signal and the second type reference signal, which reflect different gear positions, respectively.

  • Patent number: 10690236
    Abstract: A column-mounted shifter for a transmission includes a housing adapted to mount on a steering column and a shaft supported for rotation within the housing. A lever is operably coupled to the shaft and extends radially therefrom. The lever is pivotal between a series of positions corresponding to a series of modes of the transmission. Rotation of the lever causes rotation of the shaft within the housing. A sensor is configured to sense rotation of the shaft and output a signal indicative of the position of the lever. An actuator arrangement is connectable with the shaft and is configured to rotate the lever from one of the positions to another of the positions.

  • Patent number: 10690243
    Abstract: The present invention relates to a range switching device for performing range switching of an automatic transmission by using an actuator that is electrically controlled to be driven, and to a switching method thereof. A range switching device of an automatic transmission that can reduce collision noise occurring from a detent mechanism and a switching method thereof are provided. The automatic transmission includes a detent mechanism that presses a roller against a groove by using a spring, moves the roller between grooves, and determines a range position of the transmission, and a range of the transmission is changed by driving the detent mechanism by the actuator. In changing a range position of the transmission, the actuator is braked in accordance with a drawing force of the spring into a groove so that energy of the velocity when the roller reaches a target stop position can be controlled to approach zero.

  • Patent number: 10647321
    Abstract: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.
