Abstract
A kind of spline fly wheel assembly for double-clutch automatic gearbox, the spline flywheel being connected including flexible flywheel disc, with flexible flywheel disc, the spline flywheel uses disc-shaped structure, its outer ring is circumferentially with multiple boss, the boss is equipped with threaded hole, and splined hole is equipped with the spline flywheel disc centre；The flexible flywheel disc includes connecting plate, and the connecting plate is riveted by rivet and flexible disk, and the outer rim of connecting plate is arranged rack gear, crankshaft flange connecting hole is equipped with the connecting plate and flexible disk.Flexible disk is coupled by spline flywheel with double-clutch automatic gearbox, instead of fluid torque-converter into action edge transmission；On the premise of ensureing to use function, integral arrangement of the transmission system in vehicle body to design various sizes of spline flywheel, can not be influenced when carrying different vehicles according to the structure and arrangement between engine and speed changer.
Description
Technical field
The automatic transmission technical field of auto manufacturing is the utility model is related to, is used for double clutches more particularly, to one kind
The spline fly wheel assembly of device automatic transmission.
Background technology
In automotive power transmission system, speed changer is essential component, and manual transmission is step speed change driver
Structure, its advantage are that efficient, cost is low, and technical maturity, is widely used.Shortcoming is gear shift difficulty, power interruption during gear shift, it is desirable to
Driver's skilled operation, therefore it is desirable to achieve automation.
With the fast development of automotive engineering, the application of automatic gearbox is more and more extensive, AT (Automatic
Transmission), i.e., automatic transmission, its maximum benefit are the gear shift manipulations brought more convenient, comfortably drive
Multiply impression.The most automatic gear-box using fluid torque-converter of application at present, and the longest automatic change of applicating history so far
Fast case, it does not cut off power shift, have starting, gear shift it is steady, to the moment of resistance change can be adaptive the advantages that, still, AT is changed
Shelves heavy, therefore it is slow to raise speed, and pause and transition in rhythm or melody sense can be produced, reduce driving pleasure.In addition, the transmission efficiency of AT is relatively low,
Oil consumption is high.
Double-clutch automatic transmission is the automatic mechanical transmission of a new generation, it inherits manual transmission transmission
Efficient, many advantages, such as switching speed is fast, installation space is small, and possess the comfort of automatic transmission, it can provide free of discontinuities
Power output, ensure that vehicle has good dynamic property and economy.
In structure, generally coupled between engine and double-clutch automatic gearbox by fly wheel assembly；And send out
Mainly it is connected between motivation and automatic mechanical transmission using flexible flywheel disc with fluid torque-converter, will be dynamic by fluid torque-converter
Power is delivered to gearbox.
Utility model content
The utility model aim is to provide a kind of spline fly wheel assembly for double-clutch automatic gearbox, to solve to carry on the back
The technical problem mentioned in scape technology.
To solve the problems, such as in above-mentioned background technology, the technical solution adopted in the utility model is：One kind is used for double clutches
The spline fly wheel assembly of device automatic transmission, including flexible flywheel disc, the spline flywheel that is connected with flexible flywheel disc, the spline
Flywheel uses disc-shaped structure, its outer ring is circumferentially with multiple boss, and the boss is equipped with threaded hole, the spline flywheel circle
Splined hole is equipped with disk center；The flexible flywheel disc includes connecting plate, and the connecting plate is riveted by rivet and flexible disk, even
The outer rim of fishplate bar is arranged rack gear, and crankshaft flange connecting hole is equipped with the connecting plate and flexible disk.
Preferably, the flexibility plate edge is also circumferentially provided with spline flywheel connection corresponding with boss upper screwed hole
Hole, the spline flywheel connecting hole are bolted with threaded hole.
The utility model provides a kind of spline fly wheel assembly for double-clutch automatic gearbox, and flexible disk is passed through flower
Key flywheel couples with double-clutch automatic gearbox, instead of fluid torque-converter into action edge transmission；Before ensureing to use function
Put, to design various sizes of spline flywheel, can carried not according to the structure and arrangement between engine and speed changer
With vehicle when do not influence integral arrangement of the transmission system in vehicle body.Power transmission possessed by flexible flywheel disc has been adopted as heir again
Steadily, the features such as shock resistance cushion performance is high, torsional moment is big, reduces engine and is delivered to the shock loading of clutch and axially shakes
It is dynamic.And the structure of spline flywheel makes it have certain rotary inertia, by one of energy caused by engine expansion stroke
Part be stored up, to overcome the resistance of other auxiliary strokes, so that engine idling is steady, and improve engine overcome it is short
The ability of phase excess load, makes vehicle easily start to walk.
Brief description of the drawings
With reference to the accompanying drawings and detailed description, the technical solutions of the present invention will be further described.
Fig. 1 is the structure diagram of the utility model flexible flywheel disc；
Fig. 2 is the structure diagram of the utility model spline flywheel；
Fig. 3 is the structure diagram of the utility model spline fly wheel assembly.
Embodiment
From Fig. 1, Fig. 2, Fig. 3, a kind of spline fly wheel assembly for double-clutch automatic gearbox, including spline fly
Wheel 4 and flexible flywheel disc 1, spline flywheel 4 use disc-shaped structure, its outer ring is circumferentially with multiple boss 5, and boss 5 is equipped with
Threaded hole 51, is equipped with splined hole 6 at 4 disc centre of spline flywheel；Flexible flywheel disc 1 includes connecting plate 2, connecting plate 2 and flexibility
Disk 11 is arranged rack gear 3 by rivet, the outer rim of connecting plate 2, and connecting plate 2 is connected with crankshaft flange is equipped with flexible disk
Hole 31, is additionally provided with the corresponding spline flywheel connecting hole 41 of boss upper screwed hole 51 in flexible disk 11.
During work, flexible flywheel disc 1 is installed on the flange of engine crankshaft tail end, spline flywheel 4 and flexible flywheel disc 4
It is bolted, splined hole 6 and the input shaft of double clutch are interference fitted.Engine torque passes to spline by flexible disk 11
Flywheel 4, after double clutch passed to by spline.The function of flexible disk 11 is to reduce engine using the elastic characteristic of flexible disk
Pass to torsional pulse and the axial vibration of double clutch.
Finally it is pointed out that above embodiment is only the more representational example of the utility model.Obviously, originally
Utility model is not limited to above-mentioned embodiment, can also there is many deformations.Every foundation the technical essence of the utility model
Any simple modification, equivalent change and modification made to above embodiment, is considered as belonging to the utility model
Protection domain.
