<p>The drive system (4) includes a drive shaft (5) and at least one driven axle (7) with two drive wheels (6). The system is arranged so that the floor of the aisle (2) of the bus is at a height such that no steps are required for access. The shaft (5) extends into the upper part of a housing (11) at one axial end of the axle (7). The axle (7) has a spur reduction unit between the shaft (5) and an intermediate hub (17) comprising two spur gears (13 and 16), a bevel gear comprising a bevel pinion (18) carried by the intermediate hub (17) and a bevel gear (21) of a differential (22), two shafts (23 and 24) extending in opposite directions from the differential (22), and a spur reduction unit for each shaft (23 and 24) between these latter and the hubs (26) of the wheels (6) and comprising two spur gears (27 and 28). <IMAGE></p> |
