In order to improve the mechanical performance and transmission efficiency of the traditional pulsed mechanical continuously-variable transmission,a novel pulsed CVT is proposed according to the linear characteristic of hypocycloid at specific parameters and by combining the planet gear transmission mechanism with the crank slide block mechanism.

针对脉动式无级变速器动力性能差、效率低下等缺点，利用内摆线在特定条件下为直线的特性，将行星齿轮传动机构与曲柄滑块机构相结合，提出了一种新型脉动式无级变速装置。

Numerical simulation by Matlab for the new hypocycloid energy transformation mechanisms was done by means of the four-order Runge-kutta's method. The result shows that the simple harmonic and rectilinear motion of piston in the new mechanism make the engine working more stable. The peak acceleration is around 25% lower in the new mechanism than that in the conventional slider-crank mechanism. And the output speed is much higher at the same identical mean effective pressure and same load torque. And then the output power of the engine is improved.
