Abstract
The utility model discloses a vibration absorber and a flywheel component; and the flywheel component comprises a flywheel and the vibration absorber. A cavity with the corresponding diameter and size of the vibration absorber is formed on the outer side of the flywheel; at least three connecting lugs with connecting holes are uniformly distributed on the outer circumference of the vibration absorber; at least three lug-shaped grooves in the corresponding shape of the connecting lugs are correspondingly formed on the outer end surface of one side of the flywheel where the cavity is formed; the vibration absorber is embedded into the cavity of the flywheel, are mutually matched with the lug-shaped grooves through the connecting lugs, and are fixedly connected through bolts. The vibration absorber is embedded into the flywheel through the flywheel component as a whole, so that the axial space of a power assembly can be saved to the utmost extent; and compared with the conventional commonly-adopted dual mass flywheel, the structure of the flywheel component is simpler; meanwhile, the price of the flywheel component is cheaper, the disassembly and assembly are convenient, and the installation, maintenance and replacement are also convenient.
Description
Technical field
The utility model relates to the vehicle transmission technical field, is specifically related to double-clutch automatic gearbox (DCT), CVT (continuously variable transmission) (CVT), hand flywheel and the vibration damper linkage structure from speed changer, mechanical type hand automatic transmission (AMT).
Background technique
The double mass flywheel system is as the effective means that solves the automotive transmission torsional vibration, because it has advantages such as vibration damping, reduction noise, for the travelling comfort and the smoothness that improve manual car driving very big effect is arranged, we can say that double mass flywheel is the best device of vibration isolation and damping effect on the current automobile, particularly has optimal matching effect with two clutch systems (DCT), therefore extensively promoted in Europe since the nineties in last century, be generalized to intermediate-size car from limousine.
But be subject to double mass flywheel technology imperfection and factor affecting such as cost an arm and a leg at home, popularizing prospect in market is relatively dimer at home for it, and also some is hung back for using double mass flywheel even some specialize in DCT speed changer producer.
Summary of the invention
The purpose of this utility model has provided a kind of simple in structure, compact and Embedded vibration damper and flywheel assembly easy to assembly, has avoided the expensive cost of use double mass flywheel when playing vibration that the working procedure of decay by engine cycle produce and noise.
The technical solution of the utility model is as follows:
A kind of vibration damper and flywheel assembly, described assembly comprises flywheel and vibration damper.The described flywheel outside has and the corresponding cavity of described vibration damper diameter; On the excircle of described vibration damper, be evenly distributed with the engaging lug of at least three band attachment holes, have on the corresponding exterior edge face that has cavity one side at described flywheel at least three with the corresponding ear type of engaging lug shape groove, described vibration damper embeds in the cavity of flywheel, and being cooperatively interacted by engaging lug and ear type groove is connected and fixed by bolt.
The radius of described ear type groove is 10～15mm, and the degree of depth is 5～8mm.
The corresponding number of described engaging lug and ear type groove is 4～6; Described bolt is a countersunk screw.
This vibration damper fuses flywheel and vibration damper with flywheel assembly, simple in structure, vibration damper is embedded into flywheel inside, so not only helps increasing Rotary Inertia of Flywheel, but also can dwindle the axial dimension of whole drive system, can save the power assembly axial space to greatest extent.And ear type groove also makes easier for installation, helps transmitting torque and axially locating, also can therefore not reduce the inertia of flywheel simultaneously, makes huge contribution for saving cost.
This kind structure is compared to the double mass flywheel that generally adopts now, and structure is simpler, and its low price is a lot of simultaneously, and easy accessibility is convenient to install, and keeps in repair and changes.
Description of drawings
Fig. 1 is the structural representation afterwards that assembles of this assembly;
Fig. 2 is the schematic representation after the parts of this assembly decompose.
Embodiment
Below in conjunction with Figure of description, the technical solution of the utility model is made further detailed presentations.
As can be seen from Figure 2, this assembly comprises flywheel 1 and vibration damper 2.Flywheel 1 outside has and the corresponding cavity 8 of vibration damper 2 diameter.Have at flywheel 1 that to have four radiuses on the exterior edge face 6 of cavity 8 one sides be 13mm, the degree of depth is the ear type groove 4 of 7.5mm.Be evenly distributed with the engaging lug 7 of four band attachment holes accordingly on the excircle of vibration damper 2, the shape of engaging lug 7 is corresponding with ear type groove 4 shapes size.Vibration damper 2 embeds in the cavity of flywheel 1, and being cooperatively interacted by engaging lug 7 and ear type groove 4 is connected and fixed by countersunk screw 3, and the assembling back is referring to Fig. 1
The power transmission line of this assembly is: power passes to flywheel 1 by motor, four ear type grooves 4 and four countersunk screws 3 on the flywheel 1 are given vibration damper 2 with transmission of power together, vibration damper 2 decay in this course periodic vibration that motor produces and the noise that produces of face thereupon, vibration damper 2 transmission of power that optimization is closed is given transmission input shaft 5 then, thereby passes to speed changer.
