Abstract

The utility model provides a spring clutch with double diaphragms, belonging to the field of vehicles, in particular to an improvement for vehicle clutches. In order to solve the problem that the existing vehicle clutch can not achieve big torsion, the utility model provides a spring clutch with double diaphragms which can satisfy the need of the big torque for the heavy-duty vehicle; the autocompensation structure of the spring clutch with double diaphragms after the abrasion of the driven-disk assembly is that: an upper spring is adhered to the spacer pin of an upper connecting ring in manner of supporting, a middle platen is riveted with a driving sheet and an adjacent plate by rivets, and the other end of the driving sheet is connected with a lower connecting ring by bolts; the spacer pin and the middle platen conduct sliding fit, and a lower spring, a lock plate and the middle platen are adhered in manner of supporting. The spring clutch with double diaphragms has the advantages that the ability for transmitting torque for clutches with same size increases three times than the original clutch; the ability for transmitting torque is increased than new state when the process of using, and the autocompensation after the abrasion of the driven-disk assembly can be realilzed by the spacer pin, the spring and the lock plate; the clutch engaging is smooth, and the spring clutch with double diaphragms has the radial-direction vibration-damping performance.

Description

The biplate diaphragm spring clutch

Technical field:

The utility model belongs to automotive field, particularly to the improvement of automobile clutch.

Background technique:

Along with the heavy-duty car development, the high pulling torque diaphragm spring clutch plays particularly consequence, but because existing clutch is subjected to the restriction of internal structure, impossible design very big of diametrically clutch, does not also just satisfy the needs of heavy-duty car high pulling torque.

Technology contents:

In order to address the above problem, the utility model provides a kind of biplate diaphragm spring clutch that can satisfy heavy-duty car high pulling torque needs.

The utility model is made up of clutch cover and plate assembly, clutch drived disk assy, upper and lower connecting ring, center plate, flywheel etc., and clutch drived disk assy adopts two covers of stack.

The utility model clutch drived disk assy wearing and tearing back automatic compensation structure is: upper spring and last connecting ring and adjusting pin support fits, center plate is by rivet and driver blade and adjacent plate riveted joint, the driver blade the other end by bolt with under be connected articulating, adjusting pin and center plate are slidingly matched, and lower spring and jam plate and center plate support are fitted.

The utility model has the advantages that: can reach the about twice of former clutch with diameter dimension clutch transmission torque ability, the transmitting torque ability increases to some extent than new state in the using process, can realize the compensation automatically of clutch drived disk assy wearing and tearing back by adjusting pin, spring and jam plate, smooth clutch engagement also has radially damping property.

Description of drawings:

Fig. 1 is the utility model general structure schematic representation;

Fig. 2 is the utility model A-A sectional view;

Fig. 3 is the utility model B-B sectional view.

Embodiment:

The utility model is made up of clutch cover and plate assembly 1, clutch drived disk assy 2, upper and lower connecting ring 3,6, center plate 4, flywheel 7 etc., and clutch drived disk assy 2 adopts two covers of stack.

Its clutch drived disk assy wearing and tearing back automatic compensation structure is: upper spring 12 supports with last connecting ring 3 and adjusting pin 5 and fits, center plate 4 is by rivet 9 and driver blade 10 and adjacent plate 15 riveted joints, driver blade 10 the other ends are connected with following connecting ring 6 by bolt 11, adjusting pin 5 is slidingly matched with center plate 4, form self-locking with jam plate 13 simultaneously, promptly center plate 4 can be moved to the left (compensation automatically) after the clutch drived disk assy wearing and tearing, and lower spring 14 supports with jam plate 13 and center plate 4 and fits to guarantee adjusting pin 5 self-lockings.

Working principle: when with bolt with clutch and engine flywheel when fastening diaphragm spring flatten, this moment, clutch was in jointing state, clutch is delivered to gearbox by the friction moment of torsion with the moment of torsion of motor with the flywheel high speed rotating of motor, when depressing clutch pedal, clutch separation, this moment is transmitting torque not.
