| 摘要 |
<p>The invention relates to a hollow crankshaft having an axial plane of symmetry, consisting of at least two main parts (2, 3) produced by forging and weld-assembled along the longitudinal axis of the crankshaft (1). According to the invention, the two main parts (2, 3) are hollow and assembled together along a longitudinal plane (10) perpendicular to the axial plane of symmetry (x, x') of the crankshaft (1), each part comprising at least one half-journal (4), at least one counterweight (7) and at least one partial crankpin (5), a complementary partial crankpin (8) being assembled to each partial crankpin (5) of the main parts (2, 3) along an assembly plane (11) that extends parallel to the assembly plane (10) of the main parts (2, 3).</p> |
