Abstract: Compact haptic interface (100) includes a base (102) and a yoke (304) rotatably disposed within the base. A first drive coupling (312) between a first motor (301) and the yoke rotates the yoke about a yoke axis (308). A carrier (306) is mounted to the yoke and rotatable about a carrier axis (310) transverse to the yoke axis. A rod (110) mounted to the carrier extends along a rod axis (346) transverse to the yoke axis and the carrier axis. A second drive coupling (314) rotates the carrier about the carrier axis responsive to operation of a second motor (302) which is mounted to the yoke. A third motor (303) is supported on the carrier and rotatable with the carrier about the carrier axis of rotation. A third drive coupling (340) facilitates linear movement of the rod along a linear direction responsive to operation of the third motor.

Abstract: A gear box includes an output shaft defining multiple output drivers and includes a plurality of gear sets having the same diametral pitch. A common input shaft is operatively attached to each of the plurality of gear sets such that the gear sets rotate continuously and concurrently with rotation of the input shaft. Each of the output drivers is operatively attached to the output shaft and rotatably driven by a respective one of the plurality of gear sets. The multiple output drivers share a common axis of rotation with the output shaft. The output speed of the gear box may be changed by disconnecting one of the output drivers from a driven device and reconnecting another one of the output drivers to the driven device. The output speed of the gear box may be changed without having to disengage and/or change out any of the gears in the gear box.

Abstract: A method of eliminating a tooth-on-tooth position at an interlocking shifting element. The tooth-on-tooth position is eliminated by operating at least one actuator such that, during a first operating attempt the actuator is operated using a defined target parameter, after which it is checked whether as a result of the operation of the actuator the tooth-on-tooth position has been eliminated. If the tooth-on-tooth position is not eliminated, then repeating subsequent operating attempts of operation of the actuator, each time with an increased target parameter, until, after the corresponding operation of the actuator, the tooth-on-tooth position is eliminated by the m-th operating attempt. For elimination of a subsequent tooth-on-tooth position, the target parameter defined for the first elimination attempt is adapted such that the subsequent tooth-on-tooth position is eliminated by an n-th attempt.

Abstract: A gear-shifting mechanism for vehicles has a crankcase, a gearbox and a reserved room. Because the reserved room is formed between a first case of the crankcase and a body of the gearbox, a shift lever can protrude out of the first case and is mounted into the reserved room to connect to a transmission between the crankcase and the gearbox. Besides, the shift lever also can protrude out of a second case to connect to a transmission opposite to the gearbox. As a result, the shift lever can output in two directions, applicable for the gearbox in left or right of the crankcase. An engine connected to the gear-shifting mechanism can be adapted for various vehicles.
