Composite V-belt CVT

CVT institutions (CVT) is the ideal vehicle speed, and its traditional automatic transmission gears and hydraulic institutions (A / T) different, there is a pulley and the belt CVT institutions. CVT auto transmission be in two forms: friction transmission and traction drive, including the former wet rubbing metal belt, dry friction rubber V-belts and V-belt of the latter recently on the CVT.

Friction drive CVT transmission belt use is the original metal belts. Metal belts in the lubricants used in the need for greater impetus to the pulley, which will reduce the total efficiency drive.

Instead of rubber V-belt or not, and the rubber V-belt than metal belt manufacturing low-cost, and maintenance are easy to use, and therefore become targets of research and development of competing manufacturers.

But car speed V-belt use to convey the high torque, general rubber V-belt failed. If 1000 ml maximum torque of the engine, the V-belt must be able to withstand the lateral pressure of 2.0 MPa, and the general V-belt can only 0.4-0.5 MPa. To achieve such a high modulus, tension can only be used by the rubber layer (tension belt) and metal composite block (block) with a compound V to achieve such a high demand.

CVT Composite V-belt almost all of the world's famous drive Daihan in research and development, a transmission belt cutting-edge technology, this is not only the transmission belt of technical difficulty, but this is a market with the prospects are very bright. Whether in the car and have a wide range of other industrial uses.

Composite V-belt abroad has reached a practical level, such as machinery companies in Aichi, Japan and East Sakamoto jointly developed CVT system installed in the car, Suzuki Mira car. Samsung, Gates, Goodyear, and the mainland and in the development of higher special this band.
