摘要:
A transmission shifting system for axially displacing a jaw clutch having a plurality of axially and/or radially beveled teeth for engagement with a plurality of engagement cavities formed in a mainshaft gear where a ball ramp actuator or a cam ramp mechanism is used to axially displace the jaw clutch. An electrical coil is used to electromagnetically couple a control ring to the mainshaft gear using a clutch plate and an actuation ring is nonrotatably connected to the mainshaft. In an alternative embodiment, the actuation ring is formed as part of the jaw clutch and the control ring remains stationary relative to a mainshaft. A plurality of flux grooves are utilized to channel magnetic forces between the clutch plate and the mainshaft gear.
