Is the modern cvt gearbox a steel belt or a steel chain?

In the world, CVT gearboxes with biased performance all adopt chain scheme. The structural differences between chain and steel belt are as follows: 1. CVT steel belt is supported by two embedded steel belts, and hundreds of steel plates are sandwiched between metal belts. The steel belt with this push plate structure can only transmit power by "pushing", and the push plates become smaller under the action of external force by using the hardness of materials between the push plates. When power is transmitted, the driving cone wheel presses the whole side of the steel strip to form static friction, and the driving cone wheel. 2.CVT chain is obviously different from steel belt in structure. The chain does not directly contact with the helical gear, but realizes torque transmission by pressing the rocker pin in the middle. Structurally, the chain consists of two bundles of annular steel plates and pull rings, and each bundle of steel plates 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 transmit power in a "pull" way, and the driving cone wheel presses the "rocker pin" of the chain to form static friction, which drives the chain to transmit torque.
