  • Patent number: 4464945
    Abstract: In a motor vehicle gear drive a transmission block as well as a back-gear stage (7, 32), a power take-off stage (10,11) and a differential gear (39,41) for an axle drive (44) are all arranged in a common housing (20). The whole transmission is directly couplable to a driving engine (1) by way of a clutch (3). Engines with differing r.p.ms and outputs can be reduced to the same r.p.m. by means of the back-gear stage (7,32). The power take-off stage (10,11) arranged on the layshaft (6) of the back-gear stage (7,32) and having a coupling device (9) drives a reduction gear (14), at which the drive pinion shaft (15) and the output gear shaft (16,17) are led outside the housing of the reduction gear (14). In this way these shafts (15; 16,17) rotating at different r.p.m. can drive different working devices, which can be driven whether the vehicle is travelling or stationary by virtue of the controllable power take-off (10,11).
