  • Patent number: 11920675
    Abstract: A method for determining an actuating-travel range between two shift-element halves of a form-locking shift element (A, F) during an engagement of the shift element (A, F) and in the presence of a tooth-on-tooth position between the two shift-element halves is provided. An actuating movement of the at least one movable shift-element half with respect to the other shift-element half is monitored by a sensor. A tooth-on-tooth position is detected when it is determined, by the sensor, within an actuating-travel range of the at least one movable shift-element half between a disengaged condition and an engaged condition of the shift element, that the actuating movement of the movable shift-element half in the engagement direction is zero.

The lock module assembly includes a pocket plate fixedly secured to a rotating shaft. The pocket plate includes a locking element housed therein. A notch plate has first and second sets of notches with the first set complementing the pocket plate secured to the rotating shaft. A second set of notches complements a static pocket plate that houses at least clockwise actuator and at least one counterclockwise actuator. The actuators are used to control hill holds and park, whereas the locking element of the pocket plate disengages the wheel hub from the rotating shaft (neutral).

Engaging the clutch and moving the disconnect are performed such that the clutch is operatively coupled to one of the first and second gear ratios at the same time that the shifting assembly is operatively coupled to the other one of the first and second gear ratios, thus preventing torque from being transmitted through either the first and second gear ratios of the vehicle transmission to park the vehicle.

  • Patent number: 11453378
    Abstract: A method for controlling a drive train of a hybrid vehicle which includes an internal combustion engine, an electric machine that is operated as a motor or generator, and a transmission. Energy is recovered in the overrun operation of the vehicle by operating the electric machine in generator mode. The transmission has at least one free-wheel-connected low forward gear that only transmits traction torque, and at least one free-wheel-free high forward gear. When the free-wheel-connected low forward gear is engaged and the vehicle transitions into the overrun operation, or the driver requests a transition into the overrun operation by selecting the free-wheel-connected low forward gear, an overrun torque is set via the free-wheel-free high forward gear by a generator operation of the electric machine for energy recovery. The overrun torque thereby substantially corresponds to an overrun torque of a free-wheel-free configuration of the free-wheel-connected low forward gear.

    Abstract: A gear transmission having a speed changing section includes a speed changing gear for setting a speed stage and a shift gear slidably mounted on a rotation support shaft and operated to engage and disengage with the speed changing gear, the speed changing section configured to speed-change inputted power and to output the resultant power via the rotation support shaft. An arrangement is provided for facilitating engagement of the shift gear with the speed changing gear even when respective end faces of the shift gear and the speed changing gear hit each other. A transmission mechanism (20B) is provided for outputting power of a rotation support shaft (24) to a traveling device. The transmission mechanism (20B) has a transmission flexibility portion (80) which allows free rotation of the rotation support shaft (24) by a set rotation angle.

  • Patent number: 11280400
    Abstract: A selector apparatus comprises a shift lever operably supported on a base for movement between gear positions, and a feel positioner mechanism with offset detent members, where a first detent engages first undulations for biasing the shift lever toward a center of a selected gear position from a first direction, and a second detent engages second undulations for biasing the selector lever toward the center of the selected gear position from a different second direction to the common center point. By the arrangement, the first and second undulations define opposing angled slopes toward the common center point. This allows the undulations to be designed to provide any desired level of biasing force toward the center point without the limitations of a single undulation defining the center point.

  • Patent number: 11199258
    Abstract: A gear shift control system controls an actuator so that a pushing force will be a constant gearing-phase pushing force, during a gearing phase. The gear shift control system performs control on the basis of the number of rotation of the engine in the gearing phase, which is measured at the start of the gearing phase, so that the constant gearing-phase pushing force will increase as a number of rotation of the engine in the gearing phase increases. Thus, the hitting sound due to collision between the sleeve and the shift gear in shifting gears is reduced.

  • Patent number: 11199257
    Abstract: The invention relates to a drive system, a control device, and a method for controlling a mechanical shifting operation in the drive system. The drive system has at least one first multi-gear transmission, having a first input shaft and a first mechanical shifting means. Torques coming from the first input shaft are transmitted to a drive system output shaft. The torques are produced by an internal combustion engine and/or at least one first electric motor. For the purpose of disengaging a gear of the multi-gear transmission, the first electric motor is connected to the internal combustion engine and operated in a generator operating mode at least at times during the shifting operation, whereby the internal combustion engine is loaded and the first mechanical shifting means is unloaded. The mechanical shifting means is thus free of load or torsion and can be easily disconnected/opened.
