How to Avoid Slippage Between the Strip and the Pulley?

The contact area of the transmission mechanism between the pulley and the strip is small and inconstant in the changing of transmission ratio, in the extreme conditions, the case of slippage will inevitably appear. In order to improve this problem, to increase pulley clamping force can add to certain friction coefficient, but this can not completely avoid slippage between the pulley and the steel strip.

Bosch has changed the structure and the force way of transmission chain, they developed a pressure strip made up by the strip and push slices, by contrast, such a structure may have greater contact area between the pulleys, the force way from the original pull to push. Thus, both in the contact area, or in the extent of the force on the strip have a significant improvement. In addition, the strip can also by adjusting the number of push piece to change the maximum torque that can bear. Due to structural design, it cannot bend excessively, that is unable to meet too large radius variation width between the pulley.

There are a growing number of medium and large sized or strong power vehicles beginning to assemble a CVT gearbox, it is apparent that even the planetary gear automatic transmission formula is quite mature in all aspects, but in a way of performance, CVT gearbox can also find their own balance.
