The two-speed transmission apparatus for an electric vehicle comprises a planetary gear mechanism 16, a friction brake 28 and a friction clutch 26 in a coaxial arrangement between an input axis 10 and an output axis 12, the first speed is obtained by fastening the friction brake 28 and one-on-one the second speed is obtained by fastening the friction clutch 26. The electric actuator 30 to switch the first speed and the second speed comprises an electric motor 32, a torque-thrust converting mechanism 36 and a pusher 34. The torque-thrust converting mechanism 36 comprises an inside cylindrical screw 40 being rotated by the control motor 32 and an outside cylindrical nut 42 which is screwed with the cylindrical screw 40 and is connected to the pusher 34 so as to integrally axis-move. The control motor 32 may include an electromagnetic brake to fasten the friction brake 28 and the friction clutch 26. The thrust of the axial direction may be transmitted by the swing of an arm 316.

An actuator module for a driveline assembly includes, among other things, a cover housing and a fork driving unit supported by the cover housing. The fork driving unit includes a fork driver and a pusher assembly coupled to the fork driver by spaced apart pusher ends. The fork driving unit also includes a drive assembly carried by the pusher assembly to translate the fork driver relative to the cover housing. The fork driving unit further includes a spring that biases the pusher assembly and fork driver to a neutral position.

In one embodiment, an outboard marine engine comprises the internal combustion engine and a propulsor that is driven into rotation by the internal combustion engine so as to effect a thrust. The outboard marine engine further includes a transmission that shifts amongst a fourth gear wherein the thrust is forward thrust, a reverse gear wherein the thrust is a reverse thrust, and a neutral gear wherein the thrust is a zero thrust. The outboard marine engine further includes a shift rod that is rotatable about its own axis, wherein rotation of the shift rod about its own axis shifts the transmission amongst the forward gear, the reverse gear, and the neutral gear. An actuator operably connects to the internal combustion engine and causes rotation of a gear shaft. At least one gearset connects the gear shaft to the shift rod such that rotation of the gear shaft about its own axis rotates the shift rod about its own axis.

A drum cam is connected to a first annular member in a ball cam provided on a rear wheel-side output shaft. Furthermore, linear motion of a second annular member in the ball cam provided on the rear wheel-side output shaft is transmitted to a front wheel-driving clutch via a first transmission mechanism.

A torque-transmitting mechanism includes a spiral spring, an apply piston, and a rotating mechanism. The rotating mechanism is operative to rotate a member relative to the spiral spring to enforce linear movement of the spiral spring which results in linear movement of the apply piston to enforce engagement and disengagement of a torque-transmitting mechanism. The mechanism has two applications—interconnecting two rotating members, or connecting a rotating member to a ground member. The mechanism is employable in two systems. A motor drives the spiral spring with the rotation of the spring causing it to thread between stationary pins to move spring material to one side of the pins. The spiral spring pushes against the clutch plates. The motor drives the housing with pins and the spring is retained from rotating causing the spring to thread through the pins and drive the pins forward or backward. The housing presses against the clutch plates.
