VEHICLE GEARSHIFT MECHANISM Russian patent published in 2006 - IPC B60K20/02

Abstract RU 2268169 C1

FIELD: transport engineering; excavator gearboxes.

SUBSTANCE: proposed mechanism contains pusher, rod and fork. Pusher is essentially hydraulic cylinder with stepped piston and additional pistons installed on stepped piston for reciprocation both relative to stepped piston and relative to housing of hydraulic cylinder. Mechanism provides three static positions at gear-shifting independently from operating conditions.

EFFECT: no counteraction of mechanism members providing gear shifting when mechanism shifts in gears.
