Abstract

The invention discloses an automobile flywheel and a machining method. The automobile flywheel comprises a first cylinder, a second cylinder and a third cylinder which are connected. A horn-shaped groove is formed in the first cylinder and the second cylinder, four first holes arrayed annularly are formed in the bottom of the groove and are in an arc shape, and the arc central angle between the first holes is 65-75 degrees; four L-type protrusions arrayed annularly are arranged at the inner side of the groove, one protrusion is arranged between every two adjacent first holes, the vertical edge of each protrusion is tightly attached to the inner side of the groove, and the horizontal edge of each protrusion is tightly attached to the bottom face of the groove; a second hole communicated with the groove is formed in the third cylinder, and toothed grooves are formed in the inner side face of the second hole in the axial direction. The automobile flywheel is simple in structure, easy to machine and low in cost.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an auto flywheel and a processing method. Background technique [0002] The automobile flywheel is a large disc-shaped part of the engine at the rear of the crankshaft. It has a large moment of inertia and has the following functions: to store part of the energy of the engine's power stroke to overcome the resistance of other strokes and to make the crankshaft uniform. It rotates; it is equipped with a ring gear that meshes with the starter, which is convenient for the engine to start; one side of the car flywheel fits with the friction plate of the clutch installed on the flywheel, and connects the engine and the car transmission system. However, the automobile flywheel in the prior art is difficult to process and high in cost due to its complex structure. Contents of the invention [0003] The purpose of the present invention is to propose a kind of automobile flywheel an...
