Infinite three-wheeled friction gearing has inner cone and funnel-shaped cone body and one piece gearing system held by hydraulic contact pressure with cone wheels transferring rotary movement

摘要

The friction gearing has an inner cone and a funnel-shaped cone body with variable angle driven by the internal combustion engine. The three friction wheels are pressed steplessly onto three shafts (11) on the inside wall of the cone. The one piece gearing system is held by hydraulic contact pressure ready for function and transmission and the generated rotary movement is transferred to the main drive shaft through the cone wheels fixed on the shafts. The friction wheel shafts each have a guide bore and groove for the draw rod. The draw rods (16) each have a nose at the end to engage in friction wheels and push or pull the friction wheels into the guides. The cone wheel and shaft bearing sit on the drive shaft whilst the bearings enable longitudinal movement of same.
