Abstract
The invention relates to a system of structural shapes to build a line of products having gears of different total ratio or a different number of ratio steps. Transmissions (2) of vehicles consisting of three successively disposed partial gears (10, 22 40), a main gear part (22), a multi-gear split gear part (40) and a multi-gear group transmission (10) have for the split gear part (40) and the group transmission part (10) and the gear steps of each main gear part (22) in all structural shapes on all gear wheels (28, 32, 36) the same number of teeth with at least those gear wheel pairs (28-52-54, 32-50, 36-48) corresponding to the gear wheel pairs of the structural shape of the transmission (2) having the least number of gear steps.
