Power divider for motor vehicles comprising an off-road speed gear

Abstract

A transfer case for motor vehicles with off-the-road gear comprises a casing (1), an input shaft (2), a first output shaft (3), coaxial with the latter, a second output shaft (4), offset therefrom, a speed-reduction unit (5), a coupling unit (6) and an offset drive (7). The case is intended to run quietly and with little wear, be small and inexpensive. For this purpose, the speed-reduction unit (5) comprises a central drive gearwheel (11), connected in a rotationally fixed manner to the input shaft, a central driven gearwheel (12) and at least two intermediate transmissions (14), rotatable about spindles (13) fixed to the casing, each with two intermediate gearwheels (15, 16), one of which (15) meshes with the central drive gearwheel (11) and the other (16) meshes with the central driven gearwheel (12), a first driven shaft (17), connected in a rotationally fixed manner to the central drive gearwheel (11), and a hollow second driven shaft (18), connected in a rotationally fixed manner to the central driven gearwheel (12), which driven shafts lead to a coupling unit (6).
