Expanding the Versatility of the Powershift Transmission by Incorporating Electrohydraulic Control Systems

In many powershift transmission applications such as cranes, excavators, articulated vehicles, vehicles with multiple transmissions, and vehicles with remote mounted transmissions, mechanical linkage systems normally used to operate the control valve become impractical and/or expensive. After evaluating these various applications it was determined that an electrohydraulic control system has a multitude of advantages over its mechanical counterpart.

With these objectives in mind Funk Manufacturing has designed and developed a series of electrohydraulic control systems which function in concert with the Funk Shift-0-Matic transmissions.

The control valve and some of the control systems are briefly described in this paper.
