PIV stepless speed change chain is a precision transmission chain used in mechanical continuously variable transmissions (CVT). It realizes stepless speed regulation by changing the effective meshing radius of the sprocket. Its core principle is based on "friction-traction" transmission, and it has both the rigidity of gear transmission and the smooth speed change characteristics of belt transmission. It is widely used in heavy-duty scenarios that require continuous speed regulation.
