Crankshaft and method of manufacturing a crankshaft
Abstract:
A crankshaft (4) with a first central axis (A), has at least two main bearing journals (12), through which the first central axis (A) extends. At least one crankshaft web (10) is arranged between the main bearing journals (12), wherein the at least one crankshaft web (10) comprises two crank discs (14) connected with each other via a crankpin (16) with a second central axis (B). At least one crank disc (14) has a recess (26) with a planar bottom surface (28), wherein the recess (26) is adapted in the at least one crank disc (14) in such a way that the second central axis (B) of the crankpin (16) cuts the planar bottom surface (28). That planar bottom surface (28) is oriented at a right angle in relation to the direction of the second central axis (B) of the crankpin (16). A bore (30) with a third central axis (C) extend through the planar bottom surface (28) of the recess (26), through the at least one crank disc (14), and into the at least one crankpin (16). Also, a combustion engine (2), a vehicle (1) and a method for manufacture of a crankshaft (4) are disclosed.
