An alternator driving apparatus for driving an alternator may include a crank pulley mounted on a crank shaft of an engine, an alternator pulley connected to the crank pulley through a driving belt, an alternator shaft connected between the alternator and the alternator pulley, and a rotation speed varying mechanism configured to vary a rotation speed of the alternator shaft.

The damping mechanism comprising a damping element suitable for absorbing impacts from a movable part of the shift selector assembly. The damping mechanism comprising a and a support member to which the damping element is rotatably mounted. A shift selector assembly is also provided. The assembly includes a fixed part, a moveable part, a damping element, and a support member. The movable part can be moved relative to the fixed part and biased onto a contoured surface. The damping element absorbs impacts from the moveable part of the shift selector. The support member is rotatably mounted to the damping element.

A shift drum has a recess which controls a fork to move one of two cooperating coaxially arranged gears for transmitting torque in a power train of a vehicle. The recess includes a straight section, which upon rotation of the shift drum does not move the fork either to the left or the right, and at least one ramp which does move the fork in one direction (i.e., to the left or the right). The ramp is more complex than a single line, such as having a first portion at a first right-shift portion ramp angle β and a second portion at a second right-shift portion ramp angle γ, perhaps with the intersection between the first right-shift portion ramp angle β and the second right-shift portion ramp angle γ being at the mid-line defined by the straight section of the recess.

A transmission gearbox, in particular of a motor vehicle, is described including: a primary shaft receiving a driving torque via a primary transmission; a secondary shaft connected to the primary shaft. On the secondary shaft: an idle wheel revolvingly non-working on the secondary shaft including at least a coupling slot, and at least a coupling wheel revolvingly integral to the secondary shaft including a corresponding coupling tooth are assembled, respectively. The coupling wheel is arranged adjacent to the idle wheel and it can be axially moved so as to translate axially between a free configuration, where it is disengaged with respect to the idle wheel, and an engaged configuration, where it is engaged with the idle wheel by implementing a front coupling between the coupling tooth and the coupling slot for transmitting the motion between the primary shaft and the secondary shaft.

A gearshift assembly comprises a shift lever pivotable about first and second axes, a sensor assembly comprising first and second paths of sensors, and a sensor triggering element mounted on an element carrier moveably mounted in a housing and coupled to the shift lever to enable movement of the sensor triggering element along the sensors in response to movements of the shift lever. The element carrier is moveably supported by a guide structure in the housing and coupled by a hinge connection to a link with the link connected to the shift lever. The element carrier performs linear movement in response to pivoting of the shift lever about the first axis to move the sensor triggering element along the first path of sensors, and is pivoted in response to pivoting of the shift lever about the second axis to pivot the sensor triggering element along the second path of sensors.

An apparatus and system for actuating a manual gearbox, particularly of a motorcycle having a drive engine, and for carrying out a gear change while the clutch is engaged between the drive engine and the manual gearbox. The apparatus has a selector shaft, which can be actuated rotationally, and a gear-selector drum, which can be actuated rotationally. The gear-changing apparatus has a gear-change lever provided for actuating the selector shaft, and is adapted for influencing the output torque of the drive engine. One or more magnetic sensor(s), such as Hall effect sensors, are provided for sensing rotational actuation of the selector shaft and, optionally, for sensing rotational actuation of the gear selector drum. The sensor(s) send a signal to a controller and mechanisms known for affecting a change in gear to a lower or higher gear.

A vehicle includes a gearshift command input portion expandable to have a volume corresponding to a gearshift range changed by a gearshift command. The vehicle includes a gearshift command input portion, a volume of which is controlled by a control signal, is configured to receive a gearshift command for changing a gearshift range. The vehicle includes a controller configured to transmit a control signal to the gearshift command input portion in a manner that the gearshift command input portion is expanded to have a volume corresponding to the changed gearshift range. A method of controlling the vehicle includes the gearshift command input portion.

A gear shifting apparatus for a multi-speed transmission includes: a shifting unit controlling gear shifting by an actuator, and a parking unit controlling parking by the actuator. In particular, the actuator includes a control motor driving a driven gear through a drive gear externally gear-meshed with the driven gear, and the shifting and parking units are operated by a force received from a cam block fixed to the driven gear. The shifting unit includes a fork slider slidably mounted on a fork rail, a shift fork integrally formed with the fork slider, and a cam contact pin integrally formed with the fork slider and contacting the cam block.

The present disclosure provides a selector lever resetting device for a vehicle transmission. The selector lever resetting device may include a selector lever configured to select a gear position of the vehicle transmission and a lever guide device, the lever guide device having a first sliding element and a locking slide. The first sliding element may be adjustable along a first sliding axis and has a latching contour. The selector lever may be coupled to the first sliding element and configured to be moved along the sliding axis between a latching position and an operating position. The locking slide may be adjustable along a second sliding axis to move at least between a latching position and a release position.

An alternator driving apparatus for driving an alternator may include a crank pulley mounted on a crank shaft of an engine, an alternator pulley connected to the crank pulley through a driving belt, an alternator shaft connected between the alternator and the alternator pulley, and a rotation speed varying mechanism configured to vary a rotation speed of the alternator shaft.
