There is R angle in position-limited claw of the present invention 7 Yu Ping districts 4, and R angle is 0.2 ~ 0.3.
The length minimum of position-limited claw 7 of the present invention will be passed through pre-vibration damping cage plate 10, the longlyest can not exceed 1/2nd of pre-vibration damping cage plate 10 and pre-vibration damping cover plate distance.
Structure of the present invention and principle:
Core is made up of annular spring I (for original annular spring), damping ring, annular spring II (annular spring of the present invention), pre-vibration damping driven plate, pre-vibration damping cover plate, pre-vibration damping cage plate.
It is increasing annular spring II between pre-vibration damping driven plate and damping ring compared with traditional clutch for it.As shown in Figures 2 and 3, it is by position-limited claw to annular spring II, flat district and an arch area composition.Pre-vibration damping driven plate, as shown in Figure 4, and pre-vibration damping cage plate window both sides all have restraining groove.The position-limited claw of annular spring II is put in restraining groove, as shown in Figure 1.Distance between two position-limited claws will with spring 2(secondary damping spring) length just in time identical, position-limited claw is just in time stuck in spring 2(secondary damping spring like this) both sides, only have when spring 2(secondary damping spring) when compression, spring 2(secondary damping spring) just promote annular spring II and be rotated therefore and produce between damping ring friction torque, the hysteresis that namely produces this grade of vibration damping.And when spring 1(one-level damping spring) compression, spring 2(secondary damping spring) annular spring I provides positive pressure to produce friction torque while not compressing, and annular spring II does not provide friction torque.
Because annular spring II need to coordinate with pre-vibration damping driven plate, pre-vibration damping cage plate, thus position-limited claw Yu Ping district to keep substantially vertical state, to have R angle to ensure that it does not rupture simultaneously, but R angle can not be excessive, excessive, can affect assembling, the R angle of this part ensures 0.2 ~ 0.3.The length of position-limited claw also will have strict requirement, the length minimum of position-limited claw will be passed through pre-vibration damping cage plate, the longest 1/2nd (as the accompanying drawings 5) that can not exceed pre-vibration damping cage plate and pre-vibration damping cover plate distance, so both ensured spring 2(secondary damping spring) promote the rotation of annular spring II, also can not there is not interference phenomenon with pre-vibration damping cover plate even if can ensure again at the position-limited claw of parts depreciation state annular spring II.
In conventional design, there is no annular spring II, only has annular spring I, like this at spring (one-level damping spring) 1 and spring 2(secondary damping spring) compression whole process only have annular spring I that main friction torque is provided, what the hysteresis of this two-stage vibration damping just differed so is very little, does not realize the requirement of the multistage hysteresis of multistage vibration damping.When adding after annular spring II, just solve this problem.
Working principle of the present invention:
Cardinal principle is the assembly that has the every one-level vibration damping of independent adjustment lagged value.Annular spring II is to provide the critical piece of the lagged value of idling secondary vibration damping.As shown in accompanying drawing 2, Fig. 3, it is the annular spring with position-limited claw to annular spring II.Pre-vibration damping driven plate and
Pre-vibration damping cage plate is as shown in Figure 4 with restraining groove.The position-limited claw of annular spring II is put into restraining groove, as shown in Figure 1 simultaneously, the position-limited claw of annular spring II is stuck in the both sides of spring just, like this in the time not there is not corner in spring, annular spring II is not circumferentially being moved, while only having spring generation corner to produce secondary vibration damping, (spring that the label 5 shown in accompanying drawing 1 is secondary vibration damping) annular spring II starts circumferential movement, thereby produces friction, produces damping torque (being lagged value).Annular spring II is with waveform, can change of load value by adjusting waveform, i.e. and pressure, thus realize the adjustment to lagged value.
Illustrate: size and the position of pre-vibration damping driven plate and pre-vibration damping cage plate restraining groove must be suitable, restraining groove will ensure that the position-limited claw of annular spring can move freely in groove, restraining groove can not be excessive simultaneously, to the effect of radially wanting limited location of annular spring.Pre-vibration damping driven plate and pre-vibration damping cage plate fluting must be taken into account the intensity after its fluting, and what groove was opened cross conference affects working strength.So the size that groove is opened will be passed through careful accounting.
Friction plate and corrugated sheet link together with rivet, and corrugated sheet and driven disc damping disk(-isc) link together by rivet.(when flywheel rotates like this, the rotation of band movable friction plate, friction plate drives driven disc, damping disk(-isc) rotation, compress main shock-absorbing spring, make vehicle in the process of travelling, play the effect of vibration damping), bearer ring is fixed in interior hub by the form of centralized positioning, and thrust ring has four pawls to insert on four grooves on driven disc.Saucer washer acts on thrust ring, and saucer washer has the effect of adjusting main vibration damping lagged value.It is damping piece that damping ring II acts in the groove of thrust ring.Outer hub matches with interior hub, and fit angle has formed the angle of idling vibration damping.Pre-vibration damping cage plate inner side has internal tooth to match with the external tooth of interior hub.Pre-vibration damping driven plate has four pawls, is inserted in four grooves of outer hub.All there are two sulculuses the spring window both sides of (just drive pre-vibration damping driven plate and pre-vibration damping cover plate to rotate to compress pre-shock-absorbing spring when so outer hub rotation simultaneously and form idling vibration damping) pre-vibration damping cage plate and pre-vibration damping driven plate, the four paws of annular spring II extend in the groove of pre-vibration damping cage plate and pre-vibration damping driven plate, and simultaneously pre-shock-absorbing spring II plays spacing effect to annular spring II.Annular spring II only just rotates to form friction torque with pre-shock-absorbing spring II in the time of pre-shock-absorbing spring II compression in this case, and annular spring II has waveform, can provide friction torque required power.Pre-shock-absorbing spring II is the spring of idling secondary vibration damping, what annular spring II provided is exactly the hysteresis of idling vibration damping secondary, adjust the size of load value by adjusting waveform, thereby effectively adjust the size of lagged value, so because it only rotates the hysteresis of one-level vibration damping is not affected with pre-shock-absorbing spring II.Annular spring I (when one-level idling vibration damping) in the time that pre-vibration damping driven plate starts the pre-shock-absorbing spring I of rotary compression with pre-vibration damping cover plate has all participated in kinetic friction to the whole process of the pre-shock-absorbing spring II of compression.That is to say that annular spring I has impact to the hysteresis of whole idling vibration damping.Spacing dish is assemblied between pre-vibration damping cage plate and damping disk(-isc), controls the effect of bulk, and damping ring is contained between annular spring II and damping disk(-isc) and plays damping piece.
Concrete data:
1. the lagged value of traditional design one-level vibration damping and secondary vibration damping design data contrast therewith
2. traditional design designs the NVH(vibrating noise on car load therewith) Data Comparison (seeing Fig. 6 and Fig. 7)
Conclusion: Fig. 7 (multistage vibration-reducing and damping device) wants little 35% left and right than the amplitude of Fig. 6 (traditional design).
