The invention relates to a multispeed manual reverse gear unit, comprising an input shaft (1), countershafts (2, 3, 4, 5, 6, 7), and an output shaft (8). On the countershafts (2, 3, 4, 5, 6, 7), gears and/or idle gears are mounted, and said idle gears can be linked with the countershafts via clutches in a rotationally fixed manner for changing gears or the direction. The gear ratios are produced by spur pinion stages and at least one engaging and disengaging planetary stage (P). ® KIPO & WIPO 2007 |
