Power unit of a motor vehicle two-stroke engine with 2n working displacements

摘要

The invention relates to motor vehicle two-stroke engines with 2n working displacements, in which each crankshaft has three bearings. In order not to adversely affect its width dimension and, at low cost, to design the connection to the output or the interconnection of a plurality of crankshafts free from play, the crank webs rotating on both sides of the centre bearing have opposing helical toothing so that, together with the gears seated on the output shaft or the two crank web toothings of a second crankshaft arranged parallel, the balance of axial forces is established. <IMAGE>
