Abstract
734,051. Continuously-variable friction gearing. WASSILIEFF, V. April 1, 1953 [April 1, 1952], No. 9102/53. Class 80 (2). [Also in Group XXXI] In variable-speed friction gearing rollers 4 pivoted at one end to a carrier 28 engage discs 11, 12, under the action of springs 24. The members 11, 12, 28 are coaxial, one of them being axially stationary. Any of the three members may form the driving or driven members of the gearing. The rollers 4 may be cylindrical or curved convexly or concavely. The discs 11, 12 may be flat or curved. The. gearing may act on the epicyclic or non-epicyclic principle. As shown, the disc 11, Fig. 4, is axially stationary and the discs 11, 12 are driven in opposite directions from a driving shaft 18 through bevel gearing 19, 21. A shaft 29 fixed to the carrier 28 forms the driven member. Manual adjustment of the axial position of the shaft 29 varies the tilt of the rollers 4 to change the gear ratio. The rollers may be pivoted at their radially outer ends instead of at their inner ends. Some modifications embody two sets of rollers 4 and discs 11, 12. Hydraulic or pneumatic power means may be used to vary the tilt of the rollers. In a construction for driving the rear wheels of a motor-car and for steering the roller carrier 7, Fig. 5, is driven from the engine shaft 36 and the wheel axles 32, 33, are connected to the discs 11, 12. In the position shown the axles 32, 33 have equal speeds for straight driving. To move the car in a curve the rollers 4 are tilted to give differing speeds to the axles 32, 33.
