STEP-CHANGE GEARBOX

摘要

Multi-speed step-change transmission for commercial vehicles having an one input shaft, a main shaft placed in an axial extension, one countershaft parallel thereto and one intermediate shaft parallel to the two shafts for the reverse gear and the shafts have gear wheels forming the ratio steps of the transmission. The sum of the tip radii of the intermediate gear (3) for the reverse gear and of the main shaft gear (1) for the first gear is smaller than the axial separation (a) between the main shaft (5) and the intermediate shaft (6).
