Abstract
A multispeed transmission for motor vehicles includes, rotatably mounted in a gearbox housing (4), an input shaft (1) carrying fixed gear wheels and loose gear wheels, a first driven shaft (2) carrying loose gear wheels and fixed gear wheels and a second driven shaft (3), both the driven shafts (2 and 3) engaging, respectively, via first and second fixed final drive pinion (5 and 6), with a driving gear (7) of a differential (8) that drives front wheel drive shafts by way of constant velocity joints. All gears including the reverse gear are synchronized. The fixed gear wheels (10 and 12) for the first and second gears are carried on the input shaft (1). The loose gear wheels (11 and 13) for the first and second gears, together with their associated synchronizer (21), are carried on the first driven shaft (2). The second driven shaft (3) carries a loose gear wheel (20) for the reverse gear with a single-acting synchronizer ( 24), meshing with the loose gear wheels (11 or 13) of the first or second gear ratios carried on the first driven shaft (2).
