ABSTRACT:
A multi cone selector in a transmission employs sandwiched cone friction surfaces19A,20A and21A and these are shown in free or unengaged state while the corresponding friction surfaces as numerals19, 20and21are shown as engaged. This comparative illustration shows the relative positions of the surfaces at different times since the “A” surfaces and the non “A” surfaces are the same circumferential surfaces. The cone selector is used to engage free rotating gear a female part22of a multi-cone selector. A hydraulic actuator23is received by internal gear case wall24formed so as to prevent any radial or axial movement of the actuator itself. A hydraulic coupling, in this case the hydraulic coupling is formed as hydraulic springs or bags illustrated at26. The crown of hydraulic spring outlet piston is formed so as to clip in a housing of a thrust bearing29. The function of thrust bearing29is to provide relative rotational movements between cone clutch male part30and a piston of a hydraulic spring whether in idling or power transmitting mode. Twin cone selector comprises male part30, female part22and cones31and32. Cone31operates as a driving cone and is constrained but free to slide parallel to the axis of rotation in circular slots33. Cone32operates as a driven cone and is constrained but free to slide parallel to the axis of rotation in circular slots36.
