Abstract
The utility model relates to an engine part field, concretely relates to novel flexible dish of gasoline engine, including flexible set of body, flexible set of body is the disc type, and the disc middle part is the annular table rank structure of two -stage punching press, is equipped with the destressing hole near the torque converter of disc mounting hole, the destressing hole is waist shape. Annular table rank structure is passed between torque converter mounting hole and destressing hole, and whole annular table rank structure is the petal form and arranges on the disc. The utility model has the advantages of second grade stamping structure has better reduced flexible set of rigidity value, makes it softer, petal stamping structure has increased the space of arranging in destressing hole, through arranging the destressing hole, can be better, more nimble flexible set of rigidity scope of regulation, and reduce flexible set of internal stress, improve flexible set of life.
Description
Technical field
The utility model relates to engine part field, is specifically related to a kind of new-typed gasoline engine flexible disc.
Background technique
Flexible disc is installed between crankshaft rear end and gearbox, transmit Engine torque, flexible disc bears the high pulling torque that motor produces, reversed and bending operating mode simultaneously, stress form very severe, the requirement for rigidity and fatigue strength is very harsh, and rigidity is too large, easily cause stress to concentrate, occur fatigue cracking.Conventional flex dish is concentrated by adopting disk body one-level punching press and destressing hole method to reduce flexible disc rigidity and reducing stress, can not meet this petrol engine rigidity requirement, again need optimize body structure, increase destressing hole arrangement space, make it meet design requirement.
Model utility content
The purpose of this utility model is to solve the problem, and provides a kind of new-typed gasoline engine flexible disc.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of new-typed gasoline engine flexible disc, comprise flexible disc body, flexible disc body is disc type, and be the ring-shaped step structure of two-stage punching press in the middle part of disk, near the fluid torque converter mounting hole of disk, be provided with destressing hole, described destressing hole is kidney-shaped.
Ring-shaped step structure is passed between fluid torque converter mounting hole and destressing hole, and whole ring-shaped step structure is that petal-shaped is arranged on disk.
The beneficial effects of the utility model are: secondary punching structure better reduces flexible disc rigidity value, make it softer; Petal punching structure increases the arrangement space in destressing hole, by arranging destressing hole, better, more flexibly can regulate flexible disc range in stiffness, reducing flexible disc internal stress, improves flexible disc working life.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of petrol engine flexible dribbling one-level punching press,
Fig. 2 is the cross-sectional view of petrol engine flexible dribbling secondary punching press,
Fig. 3 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1, Fig. 2, Fig. 3.
A kind of new-typed gasoline engine flexible disc, comprise flexible disc body 1, flexible disc body 1 is disc type, is the ring-shaped step structure 2 of two-stage punching press, near the fluid torque converter mounting hole 3 of disk, is provided with destressing hole 4 in the middle part of disk, and described destressing hole 4 is kidney-shaped.
Ring-shaped step structure 2 is passed between fluid torque converter mounting hole 3 and destressing hole 4, and whole ring-shaped step structure 2 is arranged on disk in petal-shaped.
Specification: secondary punching structure can make design form more flexible, avoids fluid torque converter central boss and flexible disc to interfere, reduces flexible disc rigidity simultaneously, make flexible disc more flexible, reduce internal stress, reduce fatigue cracking risk.
Petal punching press shape, gets around fluid torque converter mounting hole, under square one, destressing hole layout area increases 42.8%, is conducive to offering and arranging of destressing hole, regulates flexible disc range in stiffness more broadly, reduce flexible disc stress, improve flexible disc fatigue life.
What embodiment of the present utility model announced is preferred embodiment; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and change, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
Claims (2)
1. a new-typed gasoline engine flexible disc, it is characterized in that: comprise flexible disc body, flexible disc body is disc type, is the ring-shaped step structure of two-stage punching press in the middle part of disk, near the fluid torque converter mounting hole of disk, be provided with destressing hole, described destressing hole is kidney-shaped.
2. a kind of new-typed gasoline engine flexible disc according to claim 1, is characterized in that: ring-shaped step structure is passed between fluid torque converter mounting hole and destressing hole, and whole ring-shaped step structure is that petal-shaped is arranged on disk.
