Transmission for four-wheel drive motor vehicle - has transmission stage between gear change drive output gear and first axle differential

摘要

The four-wheel drive motor vehicle has a gearbox (3) with an output gear (4), which transmits the drive to the front axle (8) and to a bevel gear (6) which drives the transmission shaft (9) for the rear axle (12) drive. The drive is transmitted to the bevel gear through a gear wheel (5), whilst the drive to the front axle is through a gear train (5, 15, 17, 18). The overall speed reduction ratio of the gear train is the same as the overall speed reduction ratio of a gear train (5, 7, 11) so that the rear axle is driven at the same speed as the front axle. ADVANTAGE - Simple improvement for cross-country vehicles.
