Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples:
A kind of work flywheel that is used for double clutch as shown in Figure 1, it comprises the first ring flywheel working plate 1 and the second ring flywheel working plate 6 that is parallel to each other and arranges, circumferential interval along the second ring flywheel working plate 6 between the first ring flywheel working plate 1 and the second ring flywheel working plate 6 is furnished with dunnage 5, being provided with joint 3, the first ring flywheel working plates 1 that are connected with engine flywheel and the second ring flywheel working plate 6 and dunnage 5 at the edge of work flywheel is the integral structure foundry goods.All offer the positioning pin hole 2 of mutual correspondence on the joint 3 of the joint 3 of the first ring flywheel working plate 1 and the second ring flywheel working plate 6.Also all offer the tapped hole 15 of mutual correspondence on the joint 3 of the joint 3 of the first ring flywheel working plate 1 and the second ring flywheel working plate 6.The inner ring of ring flywheel working plate is an intermediate throughholes 4, is beneficial to loss of weight and heat radiation.When the present invention uses, tapped hole 15 inserting bolts on the joint 3 of the work flywheel of double clutch, by this bolt the work flywheel of double clutch is fixedlyed connected with engine flywheel, positioning pin hole 2 on the joint 3 of the work flywheel of double clutch inserts locating stud 14, makes the work flywheel of double clutch and engine flywheel realize the location by this locating stud 14.
In the technique scheme, described dunnage 5 is a leaf structure, forms fan groove between adjacent two dunnages 5.Described dunnage 5 preferably has four, and these four dunnages 5 are along circumferentially being evenly arranged between the first ring flywheel working plate 1 and the second ring flywheel working plate 6.The effect of loss of weight and heat radiation is played in space between adjacent two dunnages 5.
In the technique scheme, described joint 3 is preferably sector structure, the joint 3 of the described first ring flywheel working plate 1 and the second ring flywheel working plate 6 all has four, and four joints 3 of the first ring flywheel working plate 1 are along the edge that circumferentially is evenly arranged in the first ring flywheel working plate 1; Four joints 3 of the second ring flywheel working plate 6 are along the edge that circumferentially is evenly arranged in the second ring flywheel working plate 6, joint 3 is arranged on the common outer edge of the first ring flywheel working plate 1 and the second ring flywheel working plate 6, alignment mutually on two-part joint 3 positions.
Introduce the working principle of using work fly wheel assembly of the present invention below: as shown in Figure 2, the work flywheel passes through locating stud 14 and engine flywheel 13 location, and fixedlys connected with driver blade, clutch cover by bolt; At work flywheel left end, first clutch platen 8 is connected with the work flywheel by driver blade, between first clutch platen 8 and the work flywheel first clutch drived disk assy 7 is housed; At work flywheel right-hand member, second clutch platen 12 is connected with the work flywheel by driver blade, between second clutch platen 12 and the work flywheel second clutch drived disk assy 2 is housed; Working surface does not contact between first clutch drived disk assy 7 and work flywheel, the first clutch platen 8, has certain clearance; Working surface does not contact between second clutch drived disk assy 11 and work flywheel, the second clutch platen 12, has certain clearance.
When clutch actuating mechanism drives release bearing, when promotion primary diaphragm lever 9 moved right, primary diaphragm lever 9 produced and pushes away stress, promoted first clutch platen 8 and moved right, first clutch platen 8 compresses first clutch drived disk assy 7 and work flywheel, thereby finishes the joint of clutch.Because first clutch platen 8 rotates under the drive of engine flywheel 13 with the work flywheel, this moment first, sliding rubbing took place with work flywheel, first clutch platen 8 in clutch drived disk assy 7.When clutch actuating mechanism disappears to the active force of release bearing, primary diaphragm lever 9 state that affranchises, there is pressure stress in driver blade between work flywheel and the first clutch platen 8, this moment, driver blade produced thrust to first clutch platen 8, first clutch platen 8 is pushed open, the disappearance that rubs of the cunning of work flywheel and first clutch drived disk assy 7, clutch is finished separation.In like manner joint, the separation process of second clutch platen 12, second clutch drived disk assy 11 and the flywheel of working are identical.The engaging process of second clutch drived disk assy 11 is similar, when clutch actuating mechanism drives release bearing, when promotion secondary diaphragm lever 10 moves right, 10 pairs of drag hooks of secondary diaphragm lever produce tensile stress, pulling second clutch platen 12 is moved to the left, second clutch platen 12 compresses second clutch drived disk assy 11 and work flywheel, thereby finishes the joint of clutch.Because second clutch platen 10 rotates under the drive of engine flywheel with the work flywheel, this moment second, sliding rubbing took place with work flywheel, second clutch platen 12 in clutch drived disk assy 11.When clutch actuating mechanism disappears to the active force of release bearing, secondary diaphragm lever 10 state that affranchises, there is pressure stress in driver blade between work flywheel and the second clutch platen 12, this moment, driver blade produced thrust to second clutch platen 12, second clutch platen 12 is pushed open, the synovial membrane of the work flywheel and second clutch drived disk assy 11 disappears, and clutch is finished separation.
The content that this specification is not described in detail belongs to related domain professional and technical personnel's known prior art.
