Power divider for motor vehicles comprising an off-road speed gear and a set-off-out-put

Abstract

A power-split transmission for motor vehicles with off-road travel consists of a case (), of an input shaft (), of a first output shaft () coaxial with the latter, of a second output shaft (), of a reduction unit (), of a clutch unit () and of an offset drive (). In order to make the power-split transmission compact, with low loss and low noise and synchronizable, the reduction unit () consist of: a central driving gearwheel () on a first hollow shaft (), a central ring gear () with a second hollow shaft (), first and second intermediate gearwheels () with axle fixed to the case, in each case the first intermediate gearwheel () meshing with the central driving gearwheel (), the second intermediate gearwheel () with central ring gear () and the first and second intermediate gearwheels () with one another, and a power take-off shaft (), and the clutch unit () consists of: primary parts () on the input shaft () and on the second hollow shaft (), secondary parts () on the power take-off shaft () and on the first hollow shaft (), a first shift sleeve () and a second shift sleeve () for changing over between road travel and off road travel.
