The structural difference between CVT steel belt and chain steel belt is that two embedded steel belts are used as foundation support, and hundreds of steel plates are clamped on metal belts. The steel belt with this push rod structure can only transmit power in a "push" way, and the hardness of the material between the push rods forms a thrust. The push rod has little deformation under external force. When power is transmitted, the driving cone wheel presses on the whole side of the steel belt to form static friction, and the driving cone wheel drives the driven cone wheel to rotate through the steel belt.
The structure of CVT chain is obviously different from that of steel belt. The chain does not directly contact with the helical gear, but realizes torque transmission by pressing the rocker pin in the middle. The structure of the chain consists of two bundles of annular steel plates and pull rings, and each bundle of steel belts is made of 12 high-strength thin steel plates. Patent T702 high-strength steel is inserted into each group of steel sheets to form rocker pin connection, and the tensile strength is as high as 2000mpa.
This structure of the chain can only rely on "pulling" to transmit power, and the transmission cone wheel presses the "rocker pin" of the chain to form static friction and drive the chain to transmit torque. Million car purchase subsidy
