The drive belt transmits torque from the primary cone pulley to the secondary cone pulley unit. The belt is V-shaped and consists of several hundred steel elements held together by steel strips. CVT uses a pair of cone-shaped pulleys connected by a metal belt. The key of the operation of the CVT system is a high-friction drive belt. The belt made from high performance steel, transmits drive by thrust rather than tension. The ratio of the rotations, or the gear ratio, is determined by how far the
