Abstract
A drivetrain layout that includes a primary gear reduction, a continuously variable transmission (CVT), a peak torque limiting (PTL) device and a range box is provided. The primary gear reduction is operationally engaged to an output of a motor. The CVT includes a primary pulley and a secondary pulley. The primary pulley of the CVT is operationally engaged to the primary gear reduction. The primary gear reduction reduces a rotational speed of the output of the motor that is coupled to the primary pulley of the CVT. The range box is operationally engaged with the secondary pulley of the CVT. The range box is configured to coupled torque between the CVT and wheels of a vehicle. The PTL device in operational engagement between the secondary pulley of the CVT and the range box, the PTL device configured to protect the drivetrain layout from torque transients.
