POWER UNIT FOR VEHICLE WITH INTERNAL COMBUSTION ENGINE

摘要

To provide a power unit for vehicle with internal combustion engine which is for transmitting the power of an internal combustion engine to wheels through a static oil hydraulic type non-stage transmission and which is small in the sire in the vehicle width direction and is compact. A power unit for vehicle with internal combustion engine 1 includes an internal combustion engine 20 including a cylinder block 25 having a cylinder center axis directed substantially in the vertical direction and a crankshaft 28, a static oil hydraulic type non-stage transmission 100 for speed-changing the rotation from the crankshaft 28, the static oil hydraulic type non-stage transmission 100 including a wash plate type oil hydraulic pump 110 and a swash plate type oil hydraulic motor 130 disposed coaxially, and a speed change drive shaft 151 for reciprocating a drive member 152 for changing the swash plate angle of the swash plate type oil hydraulic motor 110 or the swash plate type oil hydraulic pump 130, wherein the speed change drive shaft 151 is disposed at a position on the upper side of the static oil hydraulic type non-stage transmission 100 and i n parallel to the axis of the static oil hydraulic type non-stage transmission 100, and a plane connecting the axis of the speed change drive shaft 151 and the axis ofthe static oil hydraulic type non-stage transmission 100 does not intersect with the axis o:E the crankshaft 28, and intersects with the axis of the cylinder center axis of the cylinder block 25 at a position on the lower side of the axis of the crankshaft 28 while making an acute angle with the axis of the cylinder center axis of the cylinder block 25.
