Description

Flywheel casing of engine Technical Field The utility model relates to the technical field of engines, in particular to the technical field of engine flywheel shells. Background Flywheel shell is the cast iron piece generally, and non-deformable, and it bears the quality of derailleur, plays the effect of power transmission fulcrum, and in the use, its inside can produce a lot of heat, and some current engine flywheel casings can't accomplish when using to internal heat discharges, when its when internal heat is too high, can cause the engine unable normal use and cause the damage problem to the engine. The prior patent CN216520339U discloses a heat dissipation type engine flywheel shell, which dissipates heat through heat dissipation blades on a driver, but has the problem that the heat dissipation effect of each part inside a shell is inconsistent, the situation that the air flow in a local area is fast and fast to dissipate heat and the air flow in a local area is slow to dissipate heat is easy to occur, the whole heat dissipation effect is reduced, and the situation that the temperature of each part of the flywheel shell is inconsistent due to inconsistent heat dissipation speed is also caused, so that the flywheel shell is easy to deform and damage.
