Abstract

A fluid coupling is combined with a one way clutch for the direct drive of a wheel from a small engine. The fluid coupling is mounted in cantilevered support or two ended bearing support from a small engine and has a small diameter inner driven shaft and a larger diameter out wheel driving shaft for contacting and directly driving a wheel. The inner driven shaft connects to a pump having a relatively larger outer diameter than either the driven or driving shaft. This pump is mounted on the opposite side of the driven wheel from the engine. The one way clutch is mounted between the inner and outer driven shafts and engages with only one direction of relative rotation between the wheel and engine. At any time that the speed of the engine is less than the current rotating speed of the wheel, the clutch engages. Thus, when the engine is stopped and compression starting the engine from the wheel is desired, the ignition of the engine is connected and forward movement of the wheel directly drives the engine for compression starting. Likewise, and where dynamic braking is desired, the engine ignition is interrupted and results in compression engagement of the engine to the wheel with dynamic braking resulting.
