摘要： A return to neutral (RTN) mechanism for a variable drive apparatus having a rotatable control shaft is provided. The RTN mechanism incorporates a neutral lockdown plate secured to the housing of the variable drive apparatus and disposed about the rotatable control shaft, a control arm fixed to the control shaft to impart rotation thereto, a single, rotatable return arm piloted upon a protective cover, and a pair of springs to bias the control shaft back to a neutral position from either a forward or reverse rotation. A single spring may optionally be used to form a unidirectional RTN mechanism, or two springs having different spring rates may optionally be used to alter the return rates of the control shaft back to a neutral position.

摘要： An electric actuator for use with a drive apparatus is disclosed herein. The electric actuator has a rotary design incorporating a position sensor disposed to engage the end of a control shaft. An electric motor drives a reduction gear train to position the control shaft, the reduction gear train having a worm drive that motivates a spur gear reduction. A slip clutch is disposed between the worm drive and spur gear reduction to protect the components of the reduction gear train, and to also place a limit on the torque applied to the control shaft. The housing of the electric actuator features a motor chamber to accommodate the electric motor and is sealed by a cap having an electric connector. The actuator gears may be integrated in a common sump with the drive apparatus.
