Abstract

The invention discloses a crankshaft structure of a V-shaped six-cylinder engine. Two ends of the crankshaft are a free end and a power output end, projection is carried out along a direction from the free end to the power output end, a first toggle, a second toggle and a third toggle are sequentially arranged along the clockwise direction, an included angle between the first toggle and the second toggle is 120DEG, an included angle between the second toggle and the third toggle is 120DEG, and the firing order of the crankshaft is 1-2-3. The firing order is in favor of reducing the torsional vibration amplitude of a crankshaft system and improving the strength, the torsional oscillation and the strength of the crankshaft.

Description

technical field [0001] The invention relates to the field of engines, in particular to a crankshaft structure of a V-type 6-cylinder engine. Background technique [0002] The torsional vibration amplitude of the crankshaft of the existing V-type 6-cylinder engine is large, and the strength performance of the crankshaft is poor, and the oil supply capacity of the three-cylinder crankshaft is poor, and the oil passage layout is difficult and difficult to process. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. Contents of the invention [0004] The object of the present invention is to provide a crankshaft structure of a V-type 6-cylinder engine, so as to overcome the existing shortcomings of the crankshaf...
