Document Type and Number:
Japanese Patent JP2709856
Kind Code:
B2
Abstract:
A hydraulic ram unit for a transmission of the toroidal-race, rolling-traction type. The ram (8) is connected to the rollers (45) of the transmission so that the position of the ram within its stroke is related to the angular setting of the rollers and so to the transmitted ratio. The ram pistons (15) move within cylinders (17) the inlet (71, 73) and outlet (72, 74) ports of which are located in the cylinder end walls (24), with the outlet ports axially proud of the inlet ports. If a piston overshoots its normal stroke it tends first to restrict flow through the outlet port and then to contact and obstruct it, so creating firstly hydraulic and then contact forces to resist further overshoot, without substantially restricting the inlet port. Novel constructions for the ram (8) itself, and for the ram cylinders (17) and casing (1) are also described.
