II. Driving Characteristics of QR513 Transmission

This transmission achieves five forward gears and one reverse gear through three groups of

synchronizers and two shafts-input shaft and output shaft; all forward gears adopt conventional engagement

system while reverse gear adopts a gliding idler device. The synchronizers of the first and second gears are

installed on output shaft while the synchronizers of the third, fourth and fifth gears are installed on input

shaft. When the transmission is shifted to various gears, these synchronizers will engage with corresponding

gear hub to enable transmission of power, and then the driving gear of main decelerator will drive the driven

gear of main decelerator and differential assembly to rotate, which will drive the drive shaft to drive the

wheels to rotate.
