Abstract:
A drivetrain including a primary clutch and a secondary clutch is well-suited for use in a single-speed vehicle. The primary clutch may be automatically-engaging or manually-engaging. The secondary clutch, preferably, is normally engaged and is configured to disengage, or slip, at a threshold torque level. Desirably, the slip torque level of the secondary clutch is configured to be greater than the peak engine torque of the vehicle such that disengagement of the secondary clutch due to engine-supplied torque does not occur. In some arrangements, the slip torque level may be significantly higher than the maximum engine torque,.
