Development of a High-Efficiency CVT
Aim to conquer the low efficiency of the current auto-CVT actuated by hydraulic system, a new design was proposed based on the analysis of the energy loss, which used compounded disc spring clamp set and motorized actuation system. Through the special design of the compounded disc spring and the balance spring, the axial thrust was well counterpoised, thus it achieved the result that the actuation system could be droved by low power motor. The test results show that the CVT developed according to the new design can reduce the power consumption obviously and improve the power performance.
