Abstract
The utility model discloses a kind of high the moment of inertia fly wheel assembly, comprise flexible disc and be fixed on the gear ring of described flexible disc periphery, the middle part of described flexible disc is provided with the assembly department for being connected with bent axle, and the section thickness of described flexible disc increases gradually to outer rim from the outside of assembly department.The section thickness of flexible disc of the present utility model is change, the quality making flexible disc more all focuses on from the position away from the center of circle, thus effectively increase the moment of inertia of fly wheel assembly, under same cost, the fly wheel assembly the moment of inertia of gained can effectively increase; Flexible disc only needs shaping as required when making, technique is simple; Particularly, because the outer edge thickness of flexible disc is comparatively large, therefore can be welded direct on its outer side surface during gear ring welding, need to arrange flange in addition, effectively reduce operation, increase manufacturing efficiency further.
Description
Technical field
The utility model relates to a kind of automobile power element, is specifically related to a kind of high the moment of inertia fly wheel assembly.
Background technique
Flywheel is a castiron flying wheel, its function is stored up a part for the energy produced during motor expansion stroke, in order to overcome the resistance of other auxiliary strokes, makes bent axle Rotating with Uniform, and improve the overload capacity that motor overcomes short-term, vehicle is easily started to walk.
Known from the above description, flywheel needs to have certain the moment of inertia and could work.Prior art generally increases the moment of inertia of flywheel by the mode strengthening flywheel card area, also have Related product to increase required the moment of inertia by the mode installing inertial mass or inertia rings in card additional, aforesaid way all can produce harmful effect to flywheel fabricating cost, preparation process.
Model utility content
In order to solve above technical problem, the utility model provides a kind of high the moment of inertia fly wheel assembly, and it can effectively reduce costs, and technique is simple.
The utility model is achieved through the following technical solutions:
A kind of high the moment of inertia fly wheel assembly, comprise flexible disc and be fixed on the gear ring of described flexible disc periphery, the middle part of described flexible disc is provided with the assembly department for being connected with bent axle, and the section thickness of described flexible disc increases gradually to outer rim from the outside of assembly department.
Preferably, flexible disc is furnished with the stiffening rib of radial direction to outer rim punishment from the outside of assembly department.
Preferably, described assembly department is fixed in the middle part of flexible disc by the mode of riveted joint.
Preferably, described gear ring is fixed on the outer rim side of flexible disc by the mode of welding.
The beneficial effects of the utility model are: the section thickness of flexible disc of the present utility model is change, the quality making flexible disc more all focuses on from the position away from the center of circle, thus effectively increase the moment of inertia of fly wheel assembly, under same cost, the fly wheel assembly the moment of inertia of gained can effectively increase; Flexible disc only needs shaping as required when making, technique is simple; Particularly, because the outer edge thickness of flexible disc is comparatively large, therefore can be welded direct on its outer side surface during gear ring welding, need to arrange flange in addition, effectively reduce operation, increase manufacturing efficiency further.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is cross-sectional view.
Symbol description: 1-flexible disc, 2-gear ring, 3-assembly department, 4-mounting hole, 5-stiffening rib.
Embodiment
With reference to the accompanying drawings and the utility model will be further described in conjunction with the embodiments.
As depicted in figs. 1 and 2, fly wheel assembly of the present utility model forms primarily of flexible disc 1 and gear ring 2.Wherein flexible disc 1 entirety is disc-shaped structure, and the inner ring diameter of gear ring 2 mates with the outer circumference diameter of flexible disc 1, and gear ring 2 is fixed on the periphery of flexible disc 1.
The middle part of flexible disc 1 is provided with the assembly department 3 for being connected with bent axle, and this assembly department is provided with some mounting holes 4.In a preferred embodiment, this assembly department is an independent plate, fixing by mode and the flexible disc 1 of riveted joint.
Flexible disc 1 of the present utility model is from the outside of assembly department, and section thickness increases towards outer rim gradually, as shown in Figure 2.This structure makes the quality of flexible disc 1 comparatively focus on circumferential position place, thus increases the moment of inertia of flywheel under the prerequisite not increasing cost of material.
In order to avoid section thickness smaller part strength deficiency, flexible disc 1 is furnished with the stiffening rib 5 of radial direction to outer rim punishment from the outside of assembly department 3.This stiffening rib 5 can guarantee that flexible disc 1 bulk strength can meet usage requirement.
As shown in Figure 2, flexible disc 1 is thicker at the thickness at outer rim place, and the welding that this thickness can meet gear ring 2 uses.Therefore, gear ring 2 can be welded direct on the outer side surface of outer rim, and does not need additionally to arrange flange, thus simplifies the preparation process of flexible disc further.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (4)
1. one kind high the moment of inertia fly wheel assembly, comprise flexible disc and be fixed on the gear ring of described flexible disc periphery, the middle part of described flexible disc is provided with the assembly department for being connected with bent axle, it is characterized in that: the section thickness of described flexible disc increases gradually to outer rim from the outside of assembly department.
2. the high the moment of inertia fly wheel assembly of one according to claim 1, is characterized in that: flexible disc is furnished with the stiffening rib of radial direction to outer rim punishment from the outside of assembly department.
