Description

Multi-signal induction type engine flywheel

Technical Field

The utility model relates to a flywheel, specifically a many signal induction mode engine flywheel belongs to engine drive research and development technical field.

Background

When the automobile is started, a starter is needed to drive an engine to run, and then the automobile can be started, and the starter directly drives a flywheel. When the automobile is started, the starter is electrified to operate, the driving gear is meshed with the gear ring on the flywheel, then the starter rotates to drive the flywheel to rotate, the flywheel drives the crankshaft to rotate, and the engine operates. Therefore, the flywheel is one of the components of the engine, which is assembled with the crankshaft and is the power output element of the engine.

The flywheel is simple in structure, namely a cast iron disc, and has large moment of inertia. In order to increase the moment of inertia at the same mass, the flywheel is typically made thicker at its edges. The edge of the flywheel is generally embedded with a gear ring, and the gear ring is meshed with a starter gear when the engine is started to drive the crankshaft to rotate. The center of the flywheel is provided with a plurality of screw holes which are combined with the crankshaft into a whole through bolts. One side of the flywheel is a flat surface that contacts the clutch plate, and the other side is a special shape that is connected to the crankshaft.

The flywheel also has the more important function of increasing the uniformity of the engine operation by storing and releasing energy, and is a disk-shaped element with a high moment of inertia that acts as an energy store. The energy generated by the engine in the power stroke is partially absorbed by the flywheel besides being output externally, and then is released in the air intake stroke, the compression stroke and the exhaust stroke to compensate the work consumed in the three strokes, so that the crankshaft can overcome the resistance to continue to operate. Thus, the engine can continue to operate without stalling from consuming energy through the other three strokes. In addition, when the piston is located at the top dead center or the bottom dead center, the connecting rod is completely vertical to the crankshaft, and the power of the connecting rod cannot be transmitted to the crankshaft at the moment, namely, the connecting rod is clamped. The huge rotational inertia of the flywheel can help the piston to smoothly cross upper and lower dead points, so that an included angle is formed between the connecting rod and the crankshaft again, power is continuously transmitted, and the engine is prevented from being locked.

The hope is to develop a new function of the flywheel, namely, the flywheel is used for collecting the rotating speed signal of the engine, and no relevant research literature exists at present after retrieval.
