Abstract
A flexible flywheel panel assembly capable of reducing vibration and noise is located between an engine and a hydraulic torque converter and comprises an inertia panel body and a flexible panel body riveted to the panel surface of one side of the inertia panel body, wherein the inertia panel body is connected with an engine crankshaft flange through bolts. A starting gear ring coaxial with the inertia panel body is fixedly arranged on the periphery of the inertia panel body, and a noise reduction plate is fixed to the panel surface of the other side of the inertia panel body. The flexible flywheel panel assembly is formed by combining the starting gear ring, the inertia panel body, the flexible panel body and the noise reduction plate; the noise reduction plate fixed to the inertia panel body is formed by stamping sheet steel, and when a starter small gear and the starting gear ring are engaged, the noise reduction plate plays a role of reducing vibration amplitude, zing is restrained, starting noise of the engine is lowered, and the problems that flywheel damage, noise and the like are caused by violent vibration generated by rigid collision when a flywheel is started are effectively solved; meanwhile, the service lives of parts are prolonged.
Description
Technical field
The present invention relates to a kind of flexible flywheel disc, particularly a kind of can the flexible flywheel disc assembly of damping noise reduction.
Background technology
Flexible flywheel disc assembly is an important spare part of automatic gearshift automobile electromotor, flexible flywheel disc assembly is more relatively thin relative to the flywheel of manual transmission, it is arranged on after bent axle, gear ring in outer rim is used for engaging with starter, to start electromotor, then pass through fluid torque-converter (or bonder) and the moment of torsion of electromotor and speed are delivered to the power shaft of change speed gear box. In vehicle operation, flywheel is used for smoothing out the impulse oscillation between working stroke and providing inertia so that engine idle is steady.
Flexible flywheel disc bears many-sided different loads in the course of the work, is easily generated the problems such as crackle, deformation, vibrating noise, and impact uses function and safety, brings significantly high requirement to the design of flexible flywheel disc with manufacturing.
When engine start, the clutch gear of starter has a percussion action forward, in order to engage with starting gear ring, then drives gear ring to rotate, and then starts electromotor. Clutch gear can not successfully engage with gear ring very much, thus can produce to clash into gear ring end face, thus causing the vibration of inertia disc, and then Flywheel disc can produce dither, the sound that screams that the generation persistent period is very short. Owing to consider the many factors such as rigidity, inertia when flexible disk fly wheel assembly designs, this dither produced when starting can not be suppressed from product structure completely, while producing noise, damage the service life of part.
Summary of the invention
Present invention aim at providing the flexible flywheel disc assembly of a kind of damping noise reduction, during to solve the fly wheel start-up existed in prior art, the high vibration produced caused by rigid collision causes the technical problems such as flywheel damage and noise.
For solving the problems referred to above, the technical solution used in the present invention is: the flexible flywheel disc assembly of a kind of damping noise reduction, between electromotor and fluid torque-converter, it is characterized in that: described flexible flywheel disc assembly includes inertia disc and is riveted on the flexible disk of inertia disc side card, wherein inertia disc and engine crankshaft flange are connected with, described inertia disc outer rim is installed with the starting gear ring being coaxial therewith, and described inertia disc opposite side card is fixed with noise reducing plate.
As preferably, described inertia disc periphery is provided with multiple breach through hole, and described noise reducing plate periphery is correspondingly provided with multiple breach, and each gap edge reversely wraps up breach through hole opposite side.
As preferably, described noise reducing plate is riveted or is welded in inertia disc.
As preferably, described noise reducing plate is annular, and center is provided with circular hole.
As preferably, described noise reducing plate adopts sheet metal to be stamped to form.
As preferably, described flexible disk periphery is provided with the installing hole corresponding with breach through hole.
The present invention is constituted by starting gear ring, inertia disc, flexible disk and noise reducing plate combination, being fixed on the noise reducing plate in inertia disc adopts sheet metal to be stamped to form, noise reducing plate is when the little gear of starter engages with starting gear ring, serve the effect reducing amplitude, contain the generation of the sound that screams, reducing noise during engine start, when efficiently solving fly wheel start-up, the high vibration produced caused by rigid collision causes the problems such as flywheel damage and noise, also improves the service life of part simultaneously.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further described:
As shown in Figure 1, 2, 3, the flexible flywheel disc assembly of damping noise reduction is between electromotor and fluid torque-converter, flexible flywheel disc assembly includes inertia disc 1, flexible disk 4, flexible disk 4 is riveted on inertia disc 1 side card by riveting point 7, inertia disc 1 and engine crankshaft flange are connected with, inertia disc 1 outer rim is installed with the starting gear ring 3 being coaxial therewith, noise reducing plate 2 is riveted or is welded on and is fixed in inertia disc 1 opposite side card, noise reducing plate 2 adopts sheet metal to be stamped to form, center is provided with circular hole 21, is therefore annular. Inertia disc 1 periphery is provided with multiple breach through hole 5, and accordingly, noise reducing plate 2 periphery is correspondingly provided with multiple breach 6, and each breach 6 edge reversely wraps up breach through hole 5 opposite side. Flexible disk 4 periphery is provided with the installing hole corresponding with breach through hole 5, and flexible disk is connected with the fluid torque-converter of automobile by installing hole.
During engine start, the clutch gear of starter has a percussion action forward, in order to engage with starting gear ring 3, then drives gear ring 3 to rotate, and then starts electromotor. Gear ring 3 end face is produced to clash into by clutch gear, causes the vibration of inertia disc 1, the sound that screams that the generation persistent period is very short. The concrete structure of the noise reducing plate 2 being fixed in inertia disc 1 can reduce amplitude greatly, has contained the generation of the sound that screams, noise when reducing engine start and then engine flexible Flywheel disc is served extraordinary protective effect.
After the invention process, produce vibration amplitude caused by rigid collision during fly wheel start-up and be greatly reduced, produced by the sound that screams effectively contained.
The noise pattern of Fig. 4-7 respectively prior art and the present invention; In figure, 12 directions refer to the gear ring position in the middle of two circular holes; 3 directions refer to the gear ring position at circular hole place.
Test shows: noise reduction of the present invention is obvious, and when solving the fly wheel start-up existed in prior art, the high vibration produced caused by rigid collision causes the technical problems such as flywheel damage and noise.
