METHOD FOR REDUCING A JERK MOVEMENT GENERATED BY THE RANGE SELECTION OF A CVT GEARBOX WITH POWER BRANCHING |
摘要 |
<p>A method and a system for reducing a jerk produced by the range shift of a transmission with a power division arrangement. The transmission includes a variable speed drive in the form of a continuously variable transmission, and a pair of planetary gear sets and a pair of shift clutches to enable power to be divided between two branches within the transmission. During a range shift between two operating ranges the variable speed drive is acted upon by a short-term transmission ratio adjustment impulse in such a way that a cancellation jerk caused thereby the adjustment impulse weakens the jerk caused by the range shift.</p> |
