FINAL DRIVE OF VEHICLE Russian patent published in 2010 - IPC F16H57/02 F16H37/02 

FIELD: machine building.

SUBSTANCE: invention refers to machine building and can be used in transmissions of towing vehicles. The final drive consists of a cylinder gear including a driving gear mounted of a shaft, a driven gear mounted on a spline bushing of a torsion shaft, and a planetary gear. The planetary gear consists of a sun gear connected to the driven gear of the tooth cylinder gear by means of the torsion shaft, of a carrier mounted on a half-axle, of satellites mounted in the carrier on axles and of a crown gear rigidly fixed on the case of the rear axle. The crown gear corresponds to a plate with an aperture in a conic bottom wherein a journal bearing is installed; the crown gear is arranged in a circular aperture of the driven gear of the cylinder gear so, that plane passing through centres of rolling elements of the journal bearing is located between ends of teeth of gears of the cylinder gear.

EFFECT: reduced dimensions at maintaining reduction ratio and load capacity.
