As the engine speed increases, centrifugal force causes the weights to move outward, squeezing the sheaves together and gripping the belt. The driven clutch, or secondary clutch, is mounted on the vehicle's axle or transmission. It also features sheaves, springs, and a movable face that adjusts in response to the tension from the drive clutch and the load on the vehicle. Together, the drive and driven clutches work in harmony to provide a continuously variable gear ratio. The drive belt is a critical component that connects the drive and driven clutches. It is made of durable rubber and reinforced with cords to withstand the high tension and friction generated during operation. Proper belt tension and condition are essential for optimal performance and longevity of the torque converter system. Springs within both the drive and driven clutches play a vital role in determining the engagement characteristics and shift patterns of the torque converter. Different spring rates can be used to fine-tune the system for specific applications and driving conditions. Finally, rollers and bushings are used in the clutches to reduce friction and ensure smooth operation.
