Shield edge in window, deviates from out of vibration damping window to avoid shock-absorbing spring.In other embodiments, which can be with
It is applied on pure engine-driven vehicle.
As shown in Figure 1, driving disc spacing pressing 1 and driven disc 2 are in original state, do not relatively rotate, pre- shock-absorbing spring 14, just
It is uncompressed to shock-absorbing spring 8 and reversed shock-absorbing spring 11, pre- shock-absorbing spring 14 and pre- vibration damping driven disc window 15 and pre- vibration damping
The both ends of driving disc spacing pressing window 16 contact；Positive shock-absorbing spring 8 is contacted with the both ends of positive driving disc spacing pressing window 7, and with forward direction
There are the first positive gap 9 and the first backlass 6 at the both ends of driven disc window 17；Reversed shock-absorbing spring 11 and reversed active
The both ends of disk window 12 contact, and with the both ends of reversed driven disc window 18 there are the second positive gap 13 and second it is reversed between
Gap 10.
As shown in Figure 3 and Figure 5, when driving disc spacing pressing 1 is A relative to the counter-rotational angle of driven disc 2, pre- shock-absorbing spring 14
By compression A, the second backlass 10 disappears, and the backward end of reversed shock-absorbing spring 11 just starts to connect with reversed driven disc window 18
Touching, the angle of rotation be A during from damping effect only pre- shock-absorbing spring 14, at this time spring rate be 2*K1；When
When counter-rotational angle is greater than A and is less than C, the pre- continuation of shock-absorbing spring 14 is compressed, and reversed shock-absorbing spring 11 is reversed at this time
End contacts with reversed trigger unit 20 and starts to compress, simultaneously because the first backlass 6 of positive shock-absorbing spring 8 is greater than second instead
It is uncompressed to gap 10 plus the deflection of reversed shock-absorbing spring 11, the spring for playing damping effect only has pre- vibration damping bullet
Spring 14 and reversed shock-absorbing spring 11, spring rate is 2*K1+2*K22 at this time.
As shown in Figure 4 and Figure 5, when driving disc spacing pressing 1 is B relative to the angle that driven disc 2 rotates forward, pre- shock-absorbing spring 14
By compression B, the first positive gap 9 disappears, and the forward end of positive shock-absorbing spring 8 just starts to contact with positive driven disc window 17,
The only pre- shock-absorbing spring 14 of damping effect from during the angle of rotation is B, spring rate is 2*K1 at this time；Work as forward direction
When the angle of rotation is less than D greater than B, the pre- continuation of shock-absorbing spring 14 is compressed, at this time the forward end and forward direction of positive shock-absorbing spring 8
Trigger unit 19 contacts and starts to compress, simultaneously because the second positive gap 13 of reversed shock-absorbing spring 11 is greater than the first positive gap
9 add the deflection of positive shock-absorbing spring 8 and are uncompressed, and the spring for playing damping effect only has pre- shock-absorbing spring 14 and forward direction
Shock-absorbing spring 8, spring rate is 2*K1+2*K21 at this time.
Since the second backlass 10 is greater than the first positive gap 9, and positive shock-absorbing spring 8 and reversed shock-absorbing spring 11
Rigidity is not identical, and the difference of the spring of spring intervention acts on when making forward and reverse time difference and intervention effect realizes positive and negative
To torsion curve it is different, expand its effective torsional load working range, meet engine start/stop machine and normally travel
The torque characteristics demand of Shi Butong, reduces noise, while improving the reliability of torsional vibration damper.
