Description

A high inertia flywheel assembly

technical field

The utility model relates to an automobile power element, in particular to a high inertia flywheel assembly.

Background technique

The flywheel is an inertia wheel made of cast iron. Its function is to store part of the energy generated during the power stroke of the engine to overcome the resistance of other auxiliary strokes, make the crankshaft rotate evenly, and improve the engine's ability to overcome short-term overload. Make the vehicle easy to start.

It can be seen from the above description that the flywheel needs to have a certain amount of inertia to work. In the prior art, the inertia of the flywheel is generally increased by increasing the surface area of the flywheel. There are also related products that increase the required inertia by adding inertia blocks or inertia rings to the surface of the flywheel. The above methods will increase the production cost of the flywheel. , The production process has adverse effects.

Utility model content

In order to solve the above technical problems, the utility model provides a high inertia flywheel assembly, which can effectively reduce the cost and has a simple process.

The utility model is achieved through the following technical solutions:

A high inertia flywheel assembly, including a flexible disk and a ring gear fixed on the outer periphery of the flexible disk, the middle part of the flexible disk is provided with a mounting part for connecting with the crankshaft, the cross section of the flexible disk The thickness gradually increases from the outer side of the mounting part to the outer edge.

Preferably, radial reinforcing ribs are distributed on the flexible disc from the outer side of the mounting part to the outer edge.

Preferably, the installation part is fixed on the middle part of the flexible disk by riveting.

Preferably, the ring gear is fixed on the outer edge side of the flexible disk by welding.

The beneficial effects of the utility model are: the section thickness of the flexible disk of the utility model is changed, so that the mass of the flexible disk is concentrated at a position far from the center of the circle, thereby effectively increasing the inertia of the flywheel assembly At the same cost, the inertia of the obtained flywheel assembly can be effectively increased; the production of the flexible disk only needs to be shaped according to the needs, and the process is simple; especially, because the outer edge of the flexible disk is thicker, the teeth When the ring is welded, it can be directly welded to its outer surface without additional flanging, which effectively reduces the process and further increases production efficiency.

Figure 2 is a schematic cross-sectional structure.

Explanation of symbols: 1-flexible disk, 2-gear ring, 3-installation part, 4-installation hole, 5-reinforcing rib.

Detailed ways

The utility model will be further described below with reference to the accompanying drawings and in conjunction with the embodiments.

As shown in FIGS. 1 and 2 , the flywheel assembly of the present invention is mainly composed of a flexible disc 1 and a ring gear 2 . The flexible disc 1 has a disc-shaped structure as a whole, the inner ring diameter of the ring gear 2 matches the outer diameter of the flexible disc 1 , and the ring gear 2 is fixed on the outer circumference of the flexible disc 1 .

The middle part of the flexible disk 1 is provided with a mounting part 3 for connecting with the crankshaft, and several mounting holes 4 are provided on the mounting part. In a preferred embodiment, the mounting part is an independent plate, which is fixed to the flexible disk 1 by riveting.

The flexible disk 1 of the present utility model starts from the outside of the installation part, and the thickness of the cross-section gradually increases toward the outer edge, as shown in FIG. 2 . This structure makes the mass of the flexible disk 1 more concentrated on the outer peripheral position, thereby increasing the inertia of the flywheel without increasing the cost of materials.

In order to avoid insufficient strength at the thin section, the flexible disc 1 is provided with radial reinforcing ribs 5 distributed from the outer side to the outer edge of the mounting part 3 . The reinforcing rib 5 can ensure that the overall strength of the flexible disk 1 can meet the use requirements.

As shown in FIG. 2 , the thickness of the flexible disk 1 at the outer edge is relatively thick, which can meet the welding requirements of the ring gear 2 . Therefore, the ring gear 2 can be directly welded to the outer surface of the outer edge without additional flanges, thereby further simplifying the manufacturing process of the flexible disk.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
