Patent ID: 8091446

Claim:
A transmission for a vehicle, the transmission comprising: a casing; an output shaft positioned inside the casing and having at least one output gear; an input shaft positioned inside the casing and having at least one input gear; a reverse gear mounted onto a shaft positioned between the output shaft and the input shaft; at least one shift fork engaging one of the at least one output gear and at least one input gear; a rotatable shift drum having an axis of rotation, the shift drum operatively connected to the at least one shift fork, the shift drum and the at least one shift fork cooperating to engage at least one of the at least one output gear, the at least one input gear and the reverse gear when the shift drum is rotated, the shift drum having a body and a stopper extending from the body of the shift drum; a reverse gear locking device including a rotating shaft having a longitudinal axis, the rotating shaft adapted for rotational movement about the longitudinal axis, the longitudinal axis of the rotating shaft being substantially perpendicular to the axis of rotation of the shift drum; and a lock connected to the rotating shaft and positioned in alignment with the shift drum, the lock having an initial position where the lock is aligned with the stopper of the shift drum and prevents rotation of the shift drum to engage the reverse gear, and a second position where the lock is not aligned with the stopper of the shift drum and allows rotation of the shift drum so as to permit engagement of the reverse gear, wherein the lock is moved from the initial position to the second position by a rotational movement of the rotating shaft about the longitudinal axis.
