Drive arrangement for a motorised work vehicle

摘要

A drive arrangement (1) for a motorised work vehicle comprises a transmission case (2) for a hydrostatic continuously variable transmission which has a hydraulic pump and a hydraulic motor, with a narrow section (10) and a wide section (11) such that a step (9) is formed on one side of the transmission case (2). The hydrostatic continuously variable transmission (3) is mounted on the narrow section (10), with the result that it is accommodated within the height of the step (9). A differential (5) is provided on the wide section (11) to operate the left-hand and right-hand axles (6L, 6R) with a differential action, and a reduction gear mechanism (4) is arranged in such a way that it extends from the narrow section (10) to the wide section (11), transmitting the output power of the continuously variable transmission (3) to the differential (5) with a multi-stage reduction. The output power of the continuously variable transmission (3) can thus be transmitted to the left-hand and right-hand axles (6L, 6R) with a multi-stage reduction, and the drive arrangement for the motorised work vehicle has a more simple and compact structure.
