Abstract
A multiple-speed gearbox for motor vehicles with synchronization of all gears, includes driving and driven shafts journaled in a gear/differential case, a reverse gear axle and a differential/axle drive with axle driving shafts. The driving shaft carries fixed and loose gearwheels that engage with corresponding loose and fixed gearwheels on the driven shaft. Synchronizing units are arranged between respective pairs of loose gearwheels. The synchronizing unit for the first and second gears is arranged on the end remote from the input of the driving shaft. Loose gearwheels for the first and second gears are arranged on the driving shaft (4), and the corresponding fixed gearwheels are formed on the driven shaft.
