Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine accessories, in particular to a lightweight flywheel assembly with a reinforcing rib structure. Background Art

[0002] The flywheel assembly is a large disc-shaped part installed at the rear end of the engine crankshaft. It is an important part for the engine to transmit power. It has a large moment of inertia and can store part of the energy of the engine in the power stroke to overcome the resistance in other strokes and make the crankshaft rotate evenly.

[0003] The flywheel assembly used in the diesel engine group adopts the structure of the traditional flywheel assembly of the automobile engine, which is heavy and does not meet the lightweight requirements advocated by current energy conservation and environmental protection. Utility Model Content

[0004] In view of the above problems, the present invention provides a lightweight flywheel assembly with a reinforcing rib structure, which not only solves the problem that the flywheel assembly structure used in the diesel engine group is heavy and increases the energy consumption of the vehicle, but also provides reinforcing ribs on the crankshaft mounting side of the diesel engine group to enhance the structure of the flywheel assembly and ensure safe driving of the vehicle.

[0005] In order to achieve the above-mentioned purpose and other related purposes, the technical solution provided by the utility model is as follows:

[0006] A lightweight flywheel assembly with a reinforcing rib structure comprises a flywheel and a ring gear, the ring gear being sleeved on the rim of the flywheel, a crankshaft mounting stop being provided at the center of one side of the flywheel, a plurality of spokes being provided between the crankshaft mounting stop and the rim, the spokes being provided with reinforcing ribs, a plurality of bosses being provided at the edge of the other side of the flywheel, a clutch mounting stop being provided on the inner side of the boss, and a mounting bolt hole for a clutch cover being provided on the top of the boss.

[0007] Preferably, the flywheel is integrally cast.

[0008] Preferably, the number of the bosses is at least ten.

[0009] Preferably, the boss comprises a large boss and a small boss, and the small bosses are symmetrically arranged on both sides of the large boss.

[0010] Preferably, at least three mounting bolt holes for the clutch cover are provided on the top of the large boss, and at least one mounting bolt hole for the clutch cover is provided on the top of the small boss.

[0011] Preferably, the flywheel is a disc-like structure.

[0012] Preferably, at least eight threaded holes are provided on the inner side of the crankshaft mounting stop.

[0013] Preferably, the gear ring is in the shape of a circular ring and is integrally cast.

[0014] Preferably, the spokes are radially distributed between the crankshaft mounting stop and the wheel rim.

[0015] The utility model has the following positive effects:

[0016] 1. The utility model provides at least twelve spokes between the crankshaft mounting stop and the wheel rim. The spokes are thin and provided with reinforcing ribs. Compared with the flywheel assembly of the traditional diesel engine, the spokes are hollow structures between the spokes, which reduces the overall weight of the flywheel assembly. At the same time, the radially distributed reinforcing ribs further strengthen the structure of the flywheel assembly, which not only solves the problem that the flywheel assembly structure used in the diesel engine group is heavy and increases the energy consumption of the vehicle, but also provides reinforcing ribs on the crankshaft mounting side of the diesel engine group, which strengthens the structure of the flywheel assembly and ensures the safe driving of the vehicle.

[0017] 2. The utility model provides a boss at the edge of the other side of the flywheel, and the boss is provided with a mounting bolt hole for the clutch cover. Compared with the flywheel assembly of the traditional diesel engine, the hollow structure between the bosses further reduces the weight of the flywheel assembly, thereby reducing the energy consumption of the vehicle. Moreover, the flywheel can be integrally cast, which improves the production efficiency of the flywheel assembly, ensures appropriate rotational inertia, and meets the functional requirements of the engine group.
