Motor Vehicle Gearbox with Six Forward Gears for Normal Driving, and with a Crawling Gear or Hill Gear and a Reverse Gear

摘要

A vehicle transmission having seven forward gears and one reverse gear is described. A first forward gear is a crawling and/or hill gear having a large transmission ratio for low driving speeds, and the other forward gears are intended for normal driving. The transmission includes an input shaft, an output shaft arranged coaxially to the input shaft, an auxiliary shaft arranged parallel to the input shaft and to the output shaft, seven gearwheel stages disposed in gear set planes offset coaxially from each other. In a specified forward gear, intended for normal driving, the torque is transmitted from one gearwheel of one of the gearwheel stages to the other gearwheel of the gearwheel stage. When the crawling and/or hill gear is engaged, the torque is transmitted in the opposite direction from that in the specified forward gear over the corresponding gearwheel stage.
