Unlike classic transmissions with fixed equipment ratios, CVT gearboxes continuously vary the gear ratio to keep the engine operating in its most efficient selection.
Ratcheting CVTs can transfer substantial torque since their static friction in fact will increase relative to torque throughput, so slippage is difficult in adequately built programs. Effectiveness is mostly substantial due to the fact almost all of the dynamic friction is a result of quite slight transitional clutch pace adjustments.
