Abstract:
1. A transmission for an industrial vehicle adapted to output rotation from an engine while enabling multiple speed changes during forward and reverse travel, the transmission for an industrial vehicle comprising: an input shaft to which rotation from the engine is inputted; a first transmission mechanism including a first speed-change shaft and a plurality of gears, and configured and arranged to change the speed of rotation from the input shaft among a plurality of speeds; a second transmission mechanism, provided in parallel to the first transmission mechanism, including a second speed-change shaft and a plurality of gears, and configured and arranged to change the speed of rotation from the input shaft among a plurality of speeds; a clutch mechanism disposed on an input side of the first and second transmission mechanisms and provided with a forward clutch and a reverse clutch for switching between a forward travel state and a reverse travel state, a first snap clutch for inputting the rotation from the engine to the first speed-change shaft of the first transmission mechanism, and a second snap clutch for inputting the rotation from the engine to the second speed-change shaft of the second transmission mechanism; a rotation direction switching gear train configured and arranged to input rotations for forward travel and reverse travel to the forward clutch and the reverse clutch; a speed change gear train configured and arranged to input to the first snap clutch and the second snap clutch output from the forward clutch and the reverse clutch; an output shaft configured and arranged to output the rotation inputted from the first and second transmission mechanisms; and a counter shaft arranged parallel to the input shaft, the first and second speed-change shafts being arranged parallel to the input shaft, the forward clutch being arranged coaxially with the input shaft, the reverse clutch being arranged coaxially with the counter shaft, the first snap clutch being arranged coaxially with the first speed-change shaft, and the second snap clutch being arranged coaxially with the second speed-change shaft.
