Abstract
A system and method for operating the same includes a drive sprocket assembly, a clutch lever, a user interface generating a reverse signal at a user interface, a wheel speed sensor generating a wheel speed signal, a transmission position sensor generating a transmission position signal and a vehicle control module receiving the reverse signal, the wheel speed signal and the transmission position signal. The vehicle control module engages a reverse gear at a drive sprocket in response to the reverse signal, the wheel speed and transmission gear position and controls the drive sprocket assembly in response to the clutch lever.

A method of activating reverse for a vehicle comprising:
- generating a reverse signal at a user interface;
- communicating the reverse signal to a control module;
- determining a vehicle speed;
- determining a transmission gear position;
- generating a clutch lever signal corresponding to an amount of opening and closing of a clutch lever;
- in response to the vehicle speed and the transmission gear position, engaging a reverse gear at a drive sprocket assembly;
- and
- changing a speed of the drive sprocket assembly in response to the clutch lever signal based on the amount of opening or closing of the clutch lever.
A system comprising:
- a drive sprocket assembly;
- a clutch lever generating a clutch lever signal corresponding to an amount of opening and closing of the clutch lever;
- a user interface generating a reverse signal;
- a wheel speed sensor generating a wheel speed signal;
- a transmission position sensor generating a transmission position signal;
- and
- a vehicle control module of a vehicle receiving the reverse signal, the wheel speed signal and the transmission position signal, the vehicle control module engaging a reverse gear at a drive sprocket in response to the reverse signal, the wheel speed signal and the transmission position signal and changing a speed of the drive sprocket assembly in response to the clutch lever signal based on the amount of opening or closing of the clutch lever.
A drive sprocket assembly for a vehicle comprising:
- a first cover comprising an axial end surface relative to a transmission output shaft;
- a fixed gear fixed to the transmission output shaft, said fixed gear comprising a first outer diameter and a first inner diameter receiving the transmission output shaft;
- an intermediate gear comprising a plurality of axially extending first teeth;
- a planet carrier comprising a plurality of planetary gears a first plurality of recesses and a second plurality of axially extending teeth;
- in a first direction of operation, the first teeth of the intermediate gear engaging the first plurality of recesses on the planet carrier;
- and
- in a second direction of operation, the second plurality of axially extending teeth of the planet carrier engage a second plurality of recesses in the axial end surface of the first cover.
