TH53273B - Variable stroke engine - Google Patents

Abstract

The DC60 variable stroke engine has a crankshaft, camshaft, and turntable with an eccentric shaft, which are rotatably supported in the crankcase to maintain parallel axes. A connecting rod is connected at one end to the piston with a piston pin, and a control rod is connected at one end to the eccentric shaft. The other ends of the connecting rod and the other end of the control rod are linked together by a joint assembly, which is rotatably supported on the crankshaft. The rotational power of the crankshaft is transmitted to the camshaft and turntable, respectively. The camshaft drive wheel, which transmits rotational power to the camshaft side, is mounted on the camshaft, and the camshaft follow wheel, which is driven by the camshaft drive wheel, is mounted on the turntable.
