Abstract

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.

Die Reibradwellen (11) erhalten je eine Führungsbohrung und dazu eine Nut für die Ziehstange von 6 bis 8 mm ∅. Die Ziehstangen (16) mit je einer Nase am Ende, rasten in Reibrädern ein und ziehen oder schieben die Reibräder (8) in dieser Nut-Bohrung Führungen. Das Kegelrad (5) und Wellenlager (6) sitzen auf der Antriebswelle fest. Die Lager (4) und (9) erlauben eine Längsbewegung der Antriebswelle (3).

Diese Teile sind einzeln in Längsrichtung nicht verstellbar. Ein Vollkegel drückt auf die drei Reibräder durch hydraulische Anpresskraft und läuft gelagert mit.Stepless three-wheel friction gear with inner cone, consisting of: A funnel-shaped cone body of variable angle ( 1 ), which is driven by the internal combustion engine and three friction wheels ( 8th ) steplessly on three friction wheel shafts ( 11 ) are pressed onto the inner wall of the cone with a full cone that moves along and can be adjusted centrally. The one-piece gear system is kept translatable and functional by hydraulic contact pressure. The friction wheel shafts turn towards the drive shaft ( 11 ) attaches three bevel gears and transmit the generated rotary motion to the main drive shaft. The friction wheel shafts ( 11 ) each have a guide hole and a groove for the pull rod of 6 to 8 mm ∅.
