Abstract
The utility model relates to a driven disc assembly with a wide torsion angle for a heavy-duty vehicle, which is an improvement for the existing driven disc assembly for a heavy-duty vehicle. Vibration damping windows are changed into six to eight from nine, and one-stage damping springs and two-stage damping springs with corresponding number are arranged; wherein, the length of the two-stage vibration damping window on the driven disk is longer than the length of the two-stage vibration damping window on a damping disc for four to eight mm, and the one-stage damping spring is longer than the two-stage damping spring for four to eight mm in the free state. The improvement of the driven disc assembly with a wide torsion angle for a heavy-duty vehicle enlarges the torsion angle, which achieves the effect that the angle rigidity is reduced and the vibration damping effect is improved; the driven disc assembly with a wide torsion angle for a heavy-duty vehicle is especially suitable for the heavy-duty vehicle to use.
Description
(1) technical field: the utility model relates to parts in the automotive transmission clutch, is a kind of heavy goods vehicles with big torsion angle clutch drived disk assy.
(2) background technique: in the present domestic heavy goods vehicles clutch driven plate, because of being subjected to the restriction of driven disc structure, shock-absorbing spring can only be distributed in the driven disc in the damping disk(-isc) circumference small range; The decrement of shock-absorbing spring and the torsion angle of driven disc have been limited.Therefore clutch must hour reach required moment of torsion at corner, makes angular rigidity bigger, and effectiveness in vibration suppression is undesirable, thereby makes vehicle starting rigidity big, the time jitter phenomenon arranged.
(3) summary of the invention: it is less that the purpose of this utility model will overcome existing heavy goods vehicles clutch driven disc assembly torsion angle exactly, and the unfavorable problem of effectiveness in vibration suppression provides a kind of heavy goods vehicles with big torsion angle clutch drived disk assy.
The utility model is a kind of improvement to existing heavy goods vehicles clutch driven disc assembly, it is under the situation that does not change clutch drived disk assy basic structure, only vibration damping window, shock-absorbing spring are made local improvement, by the week to shock-absorbing spring putting allocation optimized, strengthen torsion angle, reach and reduce angular rigidity, improve effectiveness in vibration suppression.Its concrete improvement project is, all change the vibration damping window of damping disk(-isc) and driven disc into 6-8 by 9, the I and II shock-absorbing spring (alternate layout) of installing corresponding number, wherein the secondary vibration damping window on the driven disc is than long 4-8mm on the secondary vibration damping length of window on the damping disk(-isc), and the one-level shock-absorbing spring is than long 4-8mm under the secondary shock-absorbing spring free state.
In the utility model on the driven disc secondary vibration damping window than best long 6mm on the secondary vibration damping length of window on the damping disk(-isc).
The one-level shock-absorbing spring is than preferably long 6mm under the secondary shock-absorbing spring free state in the utility model.
The window of vibration damping described in the utility model is preferably designed as 8, each 4 of installing I and II shock-absorbing springs.
The decrement of the shock-absorbing spring of one-level described in the utility model is 6-12mm.
The decrement of the shock-absorbing spring of secondary described in the utility model is 5-10mm.
Improvement of the present utility model strengthens the torsion angle of clutch drived disk assy, reaches to reduce angular rigidity, improves the effect of vibration damping, is particularly suitable for heavy vehicle and uses.

Fig. 1 is a plan view of the present utility model;
Fig. 2 is a sectional view of the present utility model;
Fig. 3 is the plan view of the utility model driven disc;
Fig. 4 is the plan view of the utility model damping disk(-isc).
Among the figure: the 1-friction plate, 2-vibration damping window, the 3-spring sheet, 4-coils core, 5-one-level shock-absorbing spring, 6-secondary shock-absorbing spring, 7-driven disc, 8-damping disk(-isc), 9-rivet, 10-damping fin.
(5) embodiment:
Referring to Fig. 2, the same prior art of basic structure of the present utility model, has dish core 4, rivet 9 is adopted in its left and right sides, left and right damping disk(-isc) 8 is housed, between left and right damping disk(-isc) 8, clamp driven disc 7 and 4 damping fins 10 (driven disc 7 left and right each two), friction plate 1 is housed on the outside two sides of driven disc 7.Referring to Fig. 1, on the utility model damping disk(-isc) 8 and driven disc 7, have vibration damping window 2, the alternate I and II shock-absorbing spring 5,6 that is equipped with in the vibration damping window 2.Particularly, the utility model has been done following improvement, vibration damping window 2 is designed to eight (also can be six or seven), vibration damping window 2 is divided into one-level vibration damping window and each four alternate layout of secondary vibration damping window, wherein on the one-level vibration damping length of window on the one-level vibration damping window on the driven disc 7 and the damping disk(-isc) 8 identical (promptly identical constant with original structure), and the secondary vibration damping window L2 on the driven disc 7 is than long 4-8mm (preferably long 6mm) (referring to Fig. 3, Fig. 4) on the secondary vibration damping window L1 length on the damping disk(-isc) 8; One-level shock-absorbing spring 5 is than long 4-8mm under secondary shock-absorbing spring 6 free states (preferably long 6mm), and the decrement of one-level shock-absorbing spring 5 value among 6-12mm, the decrement of secondary shock-absorbing spring 6 value between 5-10mm.
After the utility model scheme was implemented in 380 clutch driven plates, its vibration damping torsion angle was 8.2 ° by 4.6 ° of increases.6.8 ° of pre-vibration damping angles then increase to 15 ° if add by 9.2 °.Improved effectiveness in vibration suppression greatly.
