Description
Technical field
The present invention relates to engine component field, specifically a kind of flexible flywheel.
Background technology
Flywheel is mounted in the disc parts of engine crankshaft output end, and it in rotation process there is very big rotation to be used to
Amount so that each cylinder is transferred to the vibration produced during bent axle when engine works and noise is tried one's best reduction；Meanwhile, flywheel is also
Power is transferred to the important component of gearbox.In traditional manual-gear vehicle, flywheel is the important component of clutch,
Itself and clutch friction plate contact, realize the transmission of power.But it is due to that clutch friction plate and automobile fly during use
Take turns joint place temperature very high, the abrasion of flywheel and friction plate can be aggravated；Simultaneously because manual-gear vehicle needs pin stepping on clutch
Gear shift operation can be realized, its manipulation is relative complex.With the raising of technology, when automatic catch automobile progressively turns into people's purchase automobile
First choice, it uses fluid torque-converter as disengaging part when realizing different gear switches between engine and gearbox.But
It is that it can move axially relative to engine and produce impact to engine in the fluid torque-converter course of work.In order to reduce this
The smooth rotation of engine is realized in one impact simultaneously, also needs to set flexible flywheel between fluid torque-converter and engine crankshaft.
Flexible flywheel also had certain flexibility while both having had certain rigidity, can be by self-deformation during transmission moment of torsion
Buffer impact of the fluid torque-converter to engine.
It is poor that existing flexible flywheel still suffers from pliability, transmits the jiggly problem of engine torque, in addition, it is in work
To bear to come from multidirectional different loads in state, it is easy to because stress concentration causes the disk body of flexible flywheel to produce change
The defects such as shape, crackle, influence part service life, function and safety.
The content of the invention
In view of this, the purpose of the present invention be overcome defect of the prior art there is provided a kind of pliability it is good, can be steady
Transmission engine output moment of torsion, while avoiding the occurrence of the flexible flywheel of stress concentration.
The flexible flywheel of the present invention, includes the flywheel body of sheet forming formation；The flywheel body is provided with circumferentially
The equally distributed multiple bent axle connecting holes in direction and multiple fluid torque-converter mounting holes and the close fluid torque-converter are installed
The lightening hole that hole is set；And the distribution radius of circle of the bent axle connecting hole is less than the distribution radius of circle of fluid torque-converter mounting hole；
The lightening hole is C-shaped aperture of the opening towards fluid torque-converter mounting hole.
Further, the quantity of the lightening hole is identical with the quantity of fluid torque-converter mounting hole, and lightening hole becomes with fluid power
Square device mounting hole, which is corresponded, to be set；
Further, the lightening hole is set relative to fluid torque-converter mounting hole close to flywheel body circle；
Further, the flywheel body is formed with concentric annular convex rib, and a part for the lightening hole is located at should
Annular convex rib；
Further, the cylindrical bending of the flywheel body forms annular flange, and this annular flange is circumferentially distributed letter
Number tooth；
Further, the annular flange is circumferentially distributed rectangular opening, the teeth groove of the rectangular opening formation crankshaft signal tooth；
Further, the annular flange fixed sleeves are provided with starting gear ring.
The beneficial effects of the invention are as follows：The flexible flywheel of the present invention, flywheel body is thin-walled pressing sheet material, can effectively be alleviated
The axial impact that bent axle is formed in running to flywheel, in addition, the lightening hole of the present invention is C-shaped aperture, C-shaped aperture becomes close to fluid power
Square device mounting hole is set and its open side is towards fluid torque-converter mounting hole, is subtracted compared to ellipse usually used on existing flywheel
For repeated hole, using the lightening hole of C-shaped configuration lightening hole can be made to be avoided around fluid torque-converter mounting hole, it is ensured that liquid
The bonding strength of the mounting hole of power bending moment, on the other hand, using the lightening hole of this structure, reduces fluid torque-converter peace significantly
Fill rigidity of the hole along flywheel body radial direction, it is ensured that when radial-play occurs for flywheel, do not result at the mounting hole of hydraulic moment changeable by
To destruction, in addition, the transition of c shape lightening hole hole walls is more smooth, stress collection of the flexible flywheel in real work can be reduced
In, it is ensured that the stationarity of moment of torsion transmission when engine is operated, the quality of engine is reduced, light-weight design is realized, structure is new
Grain husk, light weight, function of the engine requirement is met while reduction engine quality；Increase the toughness of flexible flywheel simultaneously,
Make transmission moment of torsion steady；The deformation preferably produced in abatement flexible flywheel operation process, greatly improves the use longevity of parts
Life.
Brief description of the drawings
