Abstract:
Apparatus for controlling the gears of a motor vehicle having a transmission including a gear box comprising a pivotable gear lever for pivoting between a plurality of gear positions corresponding to a plurality of gear positions for said transmission, hydraulic motion transmitting means for hydraulically transmitting motion between said gear lever and said gearbox, said hydraulic motion transmitting means comprising at least one primary hydraulic member mechanically coupled to said gear lever, at least one secondary hydraulic member mechanically coupled to said gearbox, and a hydraulic circuit hydraulically communicating with said at least one primary hydraulic member and said at least one secondary hydraulic member, said hydraulic circuit including a controllable flow limiter having an open position in which the hydraulic flow in said hydraulic circuit is not limited thereby and a plurality of closed positions for controllably limiting the hydraulic flow in said hydraulic circuit, whereby the movement between said plurality of gear positions for said motor vehicle transmission are controlled, wherein said at least one primary hydraulic member comprises a first primary hydraulic member and including a second primary hydraulic member, said first primary hydraulic member comprising a first piston in a first cylinder, and said second primary hydraulic member comprising a second piston in a second cylinder, and a lifting rod pivotably attached to said pivotable gear lever at a pivot point, said lifting rod including first and second arms extending from either side of said pivot point whereby said lifting rod can pivot along with said pivotable gear lever, said first piston connected to said first arm and said second piston connected to said second arm.
