How A CVT Works by TEAM Industries.mov


a continuously variable transmission is an automatic transmission that varies ratio depending on vehicle speed engine rpm and load engines have an RPM range where they deliver the best power at the best efficiency the goal of the CVT system is to allow the engine to operate at optimal power for varying vehicle driving conditions a CVT system consists of three principal components a primary clutch a secondary clutch and a bill the primary clutch has two she faces the stationary sheave which is attached to the engine crankshaft and the movable sheave which moves in and out to engage the belt an arrangement of fly weights pivots outward in response to centrifugal force these weights press on the moveable sheaf and force it towards the stationary sheath the sheaves pinch the belt engaging the CVT and transmit power to the secondary clutch the secondary clutch is mounted to the input shaft of the transmission or transaxle like the primary clutch it has a stationary and a moveable sheath belt pinch force in the secondary clutch is generated by a compression spring and a torque sensing element called a cam or helix the compression spring holds the secondary clutch closed at low ratio the helix has two or three helical surfaces that are in contact with rollers or sliding buttons attached to the clutch shaft as the throttle is depressed the primary clutch closes and tightens the belt this forces the secondary clutch sheaves to spread and shifts the CVT to a lower ratio the vehicle accelerates when the throttle is reduced the belt pinch of the primary is reduced and the secondary clutch compression spring forces the secondary sheaves close together the vehicle decelerates when the vehicle is started or accelerated under load the helix senses the increased torque and prevents the secondary clutch and the CVT from shifting to a higher ratio back shifting occurs when the helix senses increasing load this produces more torque to the ground up shifting occurs when the load is lightened these shifts occur automatically and instantly in response to vehicle load and available engine power CB T’s can be tuned to differing applications by the right choice of fly weight mass spring strength and helix angle when properly designed and tuned all of the components of a CVT system work together to transmit engine power to the ground at the optimal ratio team Industries is a market leader in drivetrain technology and is the largest US based manufacturer of CVT ‘the team’s patented cv tees are the most advanced in the market team manufactures its flood components added six manufacturing facilities this guarantees that our cv tees will be consistently manufactured to close tolerances and high engineering standards as you can see a CVT consists of three elements a primary clutch that attaches to the engine a secondary clutch that attaches to the transmission and a belt that joins the two the benefits of a CVT system arm CVTs are lightweight and relatively compact cvts are cost effective compared to other automatic transmissions maintenance repair or replacement are relatively easy rubber belted CB T’s provide an automatic shift on the fly solution for vehicles as the leading manufacturer of CB t systems in North America team is committed to developing new and innovative CVT technologies for OEMs and aftermarket our clutches are the choices of many major OEMs for their vehicles our goal is to provide solutions that add long-term value to your products and increase your customer satisfaction you
