Abstract
The invention relates to a lightweight high-ductility flexible flywheel, which comprises a flexible flywheel panel. A plurality of lightening holes are evenly distributed on an annular surface of the flexible flywheel panel except for the center of the flexible flywheel panel and are symmetric about the center of the flexible flywheel panel; and the lightening holes are special-shaped holes integrally punched with the flexible flywheel panel and are preferably special-shaped holes similar to ellipses. The lightweight high-ductility flexible flywheel has the advantages that the lightening holes are arranged on the integral structure of the lightweight high-ductility flexible flywheel and the special-shaped holes similar to the ellipses and are distributed evenly and symmetrically, stress concentration of the flexible flywheel in practical operation is decreased, torque transmission stability of an engine in running is ensured, ductility of the flexible flywheel is enhanced so that torque transmission is stable, and deformation of the flexible flywheel during running is more effectively relieved so that the service life of a part is greatly prolonged.
Description
Technical field
The present invention relates to the flexible flywheel of a kind of lightweight high tenacity.
Background technique
The flexible flywheel that automatic catch automobile uses is by the stamping forming disk of steel plate.Flexible flywheel both was connected with the flange plate of crankshaft rear end; Be connected with fluid torque converter or hydraulic couplers again, integral body has bigger rotary inertia, and main function is a stored energy; Overcome the auxiliary acting of resistance, bent axle can be rotated and transmission of power gone out reposefully.Flexible Flywheel disc and gear ring weld together, and the actuation gear engagement of gear ring and actuating motor supplies to pilot engine usefulness.
The flexible flywheel structure of present stage most of producers motor is fairly simple, and quality is heavier, and the total quality of motor is increased.Because simple in structure, quality weighs, the pliability of flexible flywheel is poor.Existing technology mainly satisfies its performance requirement from the change of material, structure and the shape of flexible disc; For example higher steel plate materials, the flexible disc body structure of working strength adopts and removes repeated hole, sets up turnup structure etc., thereby reduces the weld strength that quality is strengthened the flywheel pliability, strengthened flexible flywheel disk body and gear ring.But still exist pliability poor; It is not steady to transmit Engine torque; To bear from multidirectional different loads in working order, be easy to cause flexible flywheel disk body to produce defectives such as distortion, crackle, influence part working life, function and safety because stress is concentrated.
Summary of the invention
The purpose of this invention is to provide the flexible flywheel of a kind of lightweight high tenacity, solve the flexible flywheel pliability that present existing technology exists poor, transmit Engine torque not steadily, stress concentrates problems such as yielding.
The objective of the invention is to realize through following technological scheme:
The flexible flywheel of a kind of lightweight high tenacity comprises flexible Flywheel disc, on the excentral ring surface of flexible Flywheel disc, is evenly distributed with some repeated holes that go on the flexible Flywheel disc, and the said repeated hole that goes is symmetrically distributed about flexible Flywheel disc center; The said repeated hole that goes is the irregularly-shaped hole with the moulding of flexible Flywheel disc integrated punching, the oval-shaped irregularly-shaped hole of type of being preferably.
Said going is distributed with some fluid torque converter mounting holes between repeated hole and the flexible Flywheel disc outer ledge.
The middle part of said flexible Flywheel disc is provided with groove, is provided with pad in the groove, is distributed with the flywheel mounting hole on the pad.
Beneficial effect of the present invention is: overall structure adopts the repeated hole form of going; Remove the oval-shaped irregularly-shaped hole of repeated hole type of being and distribute symmetrically, reduced the stress of flexible flywheel in real work and concentrated, the stationarity that moment of torsion transmits when having guaranteed engine running about flexible Flywheel disc center; Reduce the quality of motor; Realize light-weight design, novel structure, light weight satisfy the engine operation performance requirement when reducing engine quality; Increase the toughness of flexible flywheel simultaneously, make transmitting torque steady; Subdue the distortion that produces in the flexible flywheel operation process better, the working life of improving component greatly.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is the structural representation of the flexible flywheel of the described lightweight high tenacity of the embodiment of the invention;
Fig. 2 is the left view of the flexible flywheel of the described lightweight high tenacity of the embodiment of the invention;
Fig. 3 is the right elevation of the flexible flywheel of the described lightweight high tenacity of the embodiment of the invention.
Among the figure:
1, flywheel ring gear; 2, flexible Flywheel disc; 3, pad; 4, flywheel mounting hole; 5, remove repeated hole; 6, fluid torque converter mounting hole; 7, groove; 8, flange.
Embodiment
Shown in Fig. 1-3; The flexible flywheel of the described a kind of lightweight high tenacity of the embodiment of the invention comprises flexible Flywheel disc 2, and the outside of said flexible Flywheel disc 2 is provided with flange 8; Flange 8 is provided with flywheel ring gear 1; Even some repeated holes 5 that go that distribute go repeated hole 5 for a type oval-shaped irregularly-shaped hole on the flexible Flywheel disc 2, go to be distributed with some fluid torque converter mounting holes 6 between repeated hole 5 and flexible Flywheel disc 2 outer ledges.The middle part of said flexible Flywheel disc 2 is provided with groove 7, is provided with pad 3 in the groove 7, is distributed with flywheel mounting hole 4 on the pad 3.Said flexible Flywheel disc 2 is the integrated punching shaping structure with removing repeated hole 5.Said flexible Flywheel disc 2 and flywheel ring gear 1 structure that is welded as a whole.
Said flywheel goes repeated hole 5 to be stamped to form with flexible Flywheel disc 2; The design of wherein removing repeated hole 5 is under the situation of equal material; Subdue the distortion that flexible flywheel running produces, avoided stress to concentrate the working life of having improved part greatly; Reduce the quality of flywheel, also reduced the complete machine quality simultaneously; Flexible Flywheel disc 2 takes flange 8 structures to be convenient to weld flywheel ring gear 1; The assurance fly wheel assembly runs well; Flywheel mounting hole site 4 is connected with the land (that is: crankshaft rear end flanged surface) of crankshaft rear end, and the fluid torque converter mounting hole site 6 on the flexible Flywheel disc 2 is used for linking of flexible Flywheel disc 2 and fluid torque converter.
The repeated hole 5 that goes among the present invention is a type oval-shaped irregularly-shaped hole, and such oval-shaped irregularly-shaped hole destressing ability is superior to circular port, and it is distributed on the flexible Flywheel disc 2 symmetrically on a large scale; Convenient processing and manufacture satisfies the light-weight design requirement, effectively reduces the total quality of motor; It is concentrated to eliminate stress; And then subdue flexible flywheel stress in movement process and concentrate the distortion that produces, the working life of improving part greatly, the stationarity that moment of torsion transmits when guaranteeing engine running; Go repeated hole 5 to be evenly arranged on the full annular face of flywheel,, effectively increased the toughness of flexible flywheel, make the Engine torque transmission steady, prolonged the working life of part about flexible Flywheel disc 2 center symmetric arrangement.
The present invention is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under enlightenment of the present invention; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technological scheme, all drops within protection scope of the present invention.
