Embodiment:
As shown in Figure 1, being a kind of medium and heavy truck clutch driven disc assembly of Ф 430, a kind of self-adaptation nonlinear is rigid
Spend control characteristic friction clutch clutch drived disk assy, including be sequentially coaxially arranged hub 16, preceding damping disc 15, front friction plate
14, driven disc 13, corrugated sheet 12, driven disc inner ring 11, flower keyboard 8, rear friction plate 17, rear damping disc 4, driver plate 2；Subtract before described
It is uniformly correspondingly arranged on 6 fenestras on the circumference of shake disk 15, driven disc inner ring 11 and rear damping disc 4, and is connected by damping spring
It connects；Around the corrugated sheet 12 be equipped with rivet hole, by rivet hole respectively with front friction plate 14, rear friction plate 17 and driven disc
13 rivetings；The preceding damping disc 15, driven disc inner ring 11, flower keyboard 8, rear damping disc 4 and driver plate 3 are equipped with rivet hole, preceding to subtract
Shake disk 15, driven disc inner ring 11, flower keyboard 8, rear damping disc 4 and driver plate 3 are connected into one by rivet；The driven disc inner ring 11
Thin damping fin 9 and thick damping fin 10 are equipped between rear damping disc 4；It is also set between the driven disc inner ring 11 and rear damping disc 4
There are damping gasket 6 and waveform spring 5；The driver plate 3 is equipped with 6 pre- damping springs 2, and pre- damping spring 2 is externally provided with pre- damping bullet
Spring cover 1, will be on the fixed driver plate 3 of pre- damping spring 2 by pre- damping spring cover 1.
As shown in Fig. 2, the damping spring, is dumbbell shape nonlinear variable-stiffness damping spring 7.
The dumbbell shape nonlinear variable-stiffness damping spring 7, line footpath and outer diameter are even variations.
The fenestra is rectangular virtual aperture window.
The damping gasket 6 is located at 12 side of corrugated sheet, and the waveform spring 5 is located at rear 4 side of damping disc.
The reason of selecting nonlinear variable-stiffness damping spring: the exciting force of engine input is nonlinear change, is commonly used
Second level driven disc damper using the different damper spring of two groups of rigidity, and spring-loaded length of window is made into size not
One, variation rigidity characteristic is obtained using the method that spring successively works, and adapt to the torsionspring of non-linear rigidity control characteristic
Variation rigidity both may be implemented in single group, and common second level rigidity torsional vibration damper performance curve is as shown in Fig. 3, and non-linear rigidity is turned round
Turn that damper performance curve is as shown in Fig. 4, it can be seen from the figure that the torsional vibration damper performance of nonlinear torsion shock-absorbing spring
The closer ideal rigidity torsion curve of curve.
The selection of nonlinear vibration reduction spring, since waist-drum-shaped shock-absorbing spring is not easy to install, middle section needs bigger space, and
And waiting line footpaths nonlinear spring is not very sensitive to pressure feedback, therefore the utility model selects dumbbell shape as shown in Fig. 2 non-
Linear variation rigidity damping spring.
Determine the structure size of the torsion damping spring of self-adaptation nonlinear stiffness tuning characteristic, as shown in Fig. 5, H is
Spring free length, D are minimum spring outer diameters, and dmax is spring maximum line footpath, dmin spring minimum line footpath, the screw pitch of t spring,
Since its line footpath and outer diameter are even variations, the spring of self-adaptation nonlinear stiffness tuning characteristic can be cut into sufficiently small
N section, it is looked at the series connection of n sections of homogenous linear helical springs, have spring rigidity series connection formula known to:Applied force F, ideally, the deflection of spring are as follows: xAlways=x1+x2+…+xn, i.e.,Due to being that spring is cut into sufficiently small n section, the lower segment of spring rate easily reaches change very much
The shape limit, so the total deformation x of spring can be obtainedAlwaysIt is not linear change with the variation of linear force F, in applied force initial stage bullet
The unit deformation amount of spring, with the increase of workload, the unit deformation amount of shock-absorbing spring is gradually reduced, so its entirety
Stiffness KAlwaysAs the increase of workload is non-linearly increasing.
Torsion damping spring static(al) simulation analysis verifying to self-adaptation nonlinear stiffness tuning characteristic: it is applied in both ends of the spring
Add linear force increase with time, with the increase of workload, the unit deformation amount Δ f of shock-absorbing spring is gradually reduced,
It knows to deform initial stage in nonlinear variable-stiffness spring stress, biggish deflection Δ f can be but obtained by lesser load, so its
It is sensitiveer to pressure value variation, there is very strong adaptivity；When the compression travel of shock-absorbing spring reaches certain degree, both ends
Simultaneously, transmitting pressure to shock-absorbing spring middle-end thick line diameter spring coil, shock-absorbing spring middle-end thick line diameter spring coil has biggish rigidity to spring coil pressure,
Great pressure value can be thus provided, i.e. the torsion damping spring of self-adaptation nonlinear stiffness tuning characteristic can provide biggish anti-
Feed voltage force value, has the function of overload protection, can be avoided main shock-absorbing spring and is overly compressed, and fills in clutch driven plate
The torsion damping spring of timing, self-adaptation nonlinear stiffness tuning characteristic is more easy to install.
When load gradually increases down, dumbbell shape shock-absorbing spring spring coil occurs and dead since big end, and number of active coils accordingly subtracts
Few, the rigidity of spring is also gradually increased, and until spring ring is pressed simultaneously completely, spring axial dimension is significantly less than commonly when spring-compressed
Helical spring, therefore the spring-loaded window size of peace can be effectively reduced.
