BEARING STRUCTURE OF CONTROL SHAFT IN VARIABLE STROKE CHARACTERISTIC ENGINE

摘要

PROBLEM TO BE SOLVED: To improve the supporting rigidity of the bearing part of a control shaft operating a variable stroke link mechanism, and to increase the variable mount of the stroke of a piston, in a variable stroke characteristics engine varying the moving stroke of the piston.;SOLUTION: In this bearing structure of the control shaft in the variable stroke characteristics engine, the piston and a crankshaft 30 are coupled to the control shaft 65 through the variable stroke link mechanism, and the control shaft 65 is driven by an actuator provided on the control shaft 65 to vary the moving stroke of the piston. The bearing wall part 52a of a bearing member 52 supporting the control shaft 65 is made from material having higher rigidity than that of a crank case 4.;COPYRIGHT: (C)2008,JPO&INPIT
