Abstract
A reverse shift device of a manual transmission is disclosed to reduce the total length of the transmission, improve shift feeling and decrease noise by excluding a reverse idler gear that rotates, while being meshed between input and output axles, the device comprising: an idle axle fixed at a shift case; and an idle synchronizer installed at the idle axle for switching a state of conveying the rotational force of an input axle to an output axle at the time of forward-reverse shifts.

A reverse shift device for a manual transmission comprising:
- an idle axle fixed to a transmission case;
- and
- an idle synchronizer installed on the idle axle for switching a state of transmitting the rotational force of an input axle to an output axle during forward-reverse shifts.
A reverse shift device for a manual transmission, comprising:
- idler gear assembly movable between an idle position and a reverse engaged position in response to a gear shift;
- a reverse drive gear mounted on an input shaft cooperating with the idler gear assembly in the reverse engaged position;
- and
- a synchronizer assembly operatively linked to said idler gear assembly and cooperating with the input shaft to stop rotation of the input shaft in response to movement of the idler gear assembly to the reverse engaged position.
A reverse shift device for transferring reverse power from a reverse drive gear mounted on an input axle to a reverse driven gear in a manual transmission, comprising:
- a fixed idle axle;
- an idler clutch gear rotatably mounted on the idle axle;
- an input gear mounted on the input axle and meshing with the idler clutch gear;
- a reverse synchronizer ring mounted on the idle axle adjacent the idler clutch gear;
- an idler sleeve mounted on the on the fixed idle axle for translation between unengaged and reverse engaged positions;
- an idler gear rotatably mounted on the idler sleeve to mesh between the reverse drive gear and reverse driven gear in the engaged position;
- means for synchronizing reverse drive gear and the idler gear when moved to the reverse engaged position.
