Mechanical transmission shifting mechanism.

摘要

An improved fluid operated (X-Y) shifting mechanism (100) is provided for shifting gears or clutches of a mechanical change gear transmission.. Mechanism (100) features a shift finger (4) that is secured to a shaft (6) that is moved in an axial (Y-Y) direction by at least one piston (12) and is pivoted in a substantially transverse (X-X) direction by at least one pistion (28), the piston (12) having a bore (10) in which an end of shaft (6) is supported and operative to rotate relative thereto to substantially lessen rotational inertia in encountered shifting in the (Y-Y) direction particularly during cold weather.
