  • Patent number: 6035956
    Abstract: An offset axle (1) for low-platform town buses. It solves the problem of making it possible to integrate disc brakes in the offset axle system without reducing the aisle width of the platform in the vehicle in the area of the axle and obtaining a sufficiently low platform level in spite of the gantry being significantly lowered owing to design requirements. Disposed eccentrically in the offset axle (1) is a differential (2) the axle shafts of which are each inserted into a drive pinion (5) of a gantry drive (3) with demultiplication effect, the drive being freely mounted in a self-centering manner between two intermediate pinions (6) each of which transmits half the drive power to a spur wheel (7) in order to drive the wheels. Owing to the two gantry drives (3), the axle shafts (4) are lower than the wheel axles by the depth of the gantry. The axle shafts (4) are mounted eccentrically on the upper edge of the interior of the axle bridge housing (8).
