Driving arrangement for a track-adjustable motor vehicle bearing axle having selectively drivable wheels

A driving arrangement for a motor vehicle bearing axle having selectively drivable wheels, comprising:

• a track-adjustable beraing axle having a bridge at a central portion thereof, first and second half-axles each having first and second ends, and a recess formed in an upper portion of at least one of said bridge and said half-axles, each half-axle being axially adjustably attachable to said bridge;
• first and second wheels rotatably and swivellably supported at said half-axle second ends, respectively;
• first and second rotatable spur gearings at said half-axle second ends, respectively, drivably engageable with said first and second wheels, respectively;
• first and second rotatable input shafts drivably engageable with said first and second spur gearings, respectively, each said input shaft being of telescopic construction and extending along said bearing axle in said recess from said central portion towards the corresponding spur gearing;
• first and second clutches located at said half-axle second ends, respectively, for selectively engaging and disengaging the corresponding input shaft, spur gearing and wheel depending upon a degree and direction of relative rotation between said input shaft and said wheel;
• first and second swivel housing at said half-axle second ends, respectively, each said swivel housing being disposed substantially within the corresponding wheel and substantially enclosing the corresponding spur gearing and clutch;
• and
• driving means for rotatably driving each said input shaft at an end thereof towards said cental portion.

A driving arrangement for at least one wheel mounted on a bearing axle, comprising:

• a driving means;
• a bearing axle having a housing for said driving means, a bridge and a pair of half-axles, said half-axles being axially adjustably attachable to said bridge in a plurality of positions, and a recess formed in upper surfaces of said bridge and said half-axles;
• a swivel housing swivellably mounted at each of said bearing axle;
• a wheel rotatably supported by each said swivel housing;
• gearing means disposed substantially within each said swivel housing and drivably connected to the coresponding wheel;
• rotatable telescopic input shafts for drivably coupling the driving means to each of the gearing means;
• and
• a clutch disposed substantially within each said swivel housing and selectively engaging and disengaging the corresponding input shaft and gearing means depending upon a degree and direction of relative rotation between said input shaft and said wheel.
