A MULTI CONE SELECTOR IN A TRANSMISSION EMPLOYS SANDWICHED CONE FRICTION SURFACES (19A, 20A, 21A) AND THESE ARE SHOWN IN FREE OR UNENGAGED STATE WHILE THE CORRESPONDING FRICTION SURFACES AS NUMERALS (19, 20, 21) ARE 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 PART (22) OF A MULTI-CONE SELECTOR.A HYDRAULIC ACTUATOR (23) IS RECEIVED BY INTERNAL GEAR CASE WALL (24) FORMED 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 AT (26). THE CROWN OF HYDRAULIC SPRING OUTLET PISTON IS FORMED SO AS TO CLIP IN A HOUSING OF A THRUST BEARING (29). THE FUNCTION OF THRUST BEARING (29) IS TO PROVIDE RELATIVE ROTATIONAL MOVEMENTS BETWEEN CONE CLUTCH MALE PART (30) AND A PISTON OF A HYDRAULIC SPRING WHETHER IN IDLING OR POWER TRANSMITTING MODE.TWIN CONE SELECTOR COMPRISES MALE PART (30), FEMALE PART 22) AND CONES (31, 32). CONE (31) OPERATES AS A DRIVING CONE AND IS CONSTRAINED BUT FREE TO SLIDE PARALLEL TO THE AXIS OF ROTATION IN CIRCULAR SLOTS (33). CONE (32) OPERATES AS A DRIVEN CONE AND IS CONSTRAINED BUT FREE TO SLIDE PARALLEL TO THE AXIS OF ROTATION IN CIRCULAR SLOTS (36).(FIG 4) |
