Description
Technical field
The invention belongs to auto parts machinery processing technique field.
Background technique
The main function of clutch cuts off and realizes the transmission of power of motor to power train, by motor and the smooth-going combination of power train when ensureing vehicle starting, guarantees that automobile balance is started to walk.In clutch cover and plate assembly, main part has diaphragm spring, lid, platen.Since being invented from diaphragm spring clutch, the diaphragm spring in cap assembly and lid part are constantly being improved always, and almost do not have the innovative design of platen, and this project is launched for this part of platen.
Clutch compressing disc is lower in working order to be engaged with friction plate, and play carry-over moment effect, during separation, large of platen and clutch drived disk assy rubbing surface separate, and cut off moment transmission.Design of platens should have larger rigidity, make the pressure distribution of impacting force on rubbing surface evenly and reduce the buckling deformation after being heated, in order to avoid affect the even compression of friction plate and the thorough separation of clutch, platen should have larger quality simultaneously, to increase thermal capacity, reduce temperature, prevent it from cracking and fragmentation.As can be seen here, the boundary dimension of platen produce when clutch transmission torque size, sliding wear heat, in conjunction with time temperature raise, heat dispersal situations and play vital effect in friction disc wear etc.
And under many circumstances, the size of clutch is limited by several factors, because in general, the exploitation of clutch is all in the bulk coordinating engine flywheel and car load assembling, so the design size of clutch assembly and each part can be subject to strict restriction.Will in confined space size, the performance parameter of lifting clutch and working life, be exactly one of most important problem in clutch research and development as far as possible.
Summary of the invention
The object of the invention is by the innovative design to press plate structure, in limited radial space, improve space availability ratio, its intensity can not only be increased, and increase the increase clutch torque capacity press plate structure of effective use size of platen part as much as possible.
Driver blade one end of the present invention by lid rivet on clutch cover, the other end inwardly by platen rivet on platen, outside the platen of platen rivet and platen riveted joint place, have riveted holes, platen rivet is placed in riveted holes completely; The riveted holes position of the corresponding platen of driver blade must be square uninterruptedly in lid supporting rivet hole, and this hole is arranged in the middle of platen internal-and external diameter.
The data demand that the present invention inwardly rivets driver blade is: the lift h of clutch assembly, and platen riveted joint face and lid riveted joint face height fall must meet h

Embodiment
Driver blade 7 one end of the present invention is riveted on clutch cover 2 by lid rivet 8, and the other end is inwardly riveted on platen 2 by platen rivet 6, and outside platen rivet 6 with the platen of platen 2 riveted joint place, have riveted holes 5, platen rivet 6 is placed in riveted holes 5 completely; The riveted holes (i.e. driver blade platen hole 10) of the corresponding platen 2 of driver blade 7 does not interfere other local, and this hole is arranged in the middle of platen internal-and external diameter.
The data demand that the present invention inwardly rivets driver blade 7 is: the lift h of clutch assembly, and platen riveted joint face and lid riveted joint face height fall must meet h

Below in conjunction with accompanying drawing, the present invention is described in detail:
Clutch cover and platen are carried out rivet interlacement by driver blade by the present invention, in limited space, design platen, in order to increase clutch torque capacity, by the design of platen link position inside platen, reduce space.
As can be seen from Figure 6, innovation platen without traditional ear structure, but will need the rivet hole of riveting with driver blade to move to large face, and this kind of structure possesses in the following aspects the advantage that traditional platen do not have:
intensity aspect, by the contrast of two kinds of platens, an effect cancels platen ear structure exactly the most intuitively, thus completely avoid the risk of ear place fracture, and overall intensity is better, more durable.The design of tradition platen lug, at 7-8mm, there is crackle by during rivet interlacement in thickness, None-identified causes in use lug fracture.Innovation platen attachment hole thickness is 13-15mm, without connecting application risk.
transmitting torque aspectwhen space greatest diametrical dimension is determined, tradition platen is due to the restriction of ear structure, maximum functional external diameter is much less than maximum space diameter, and work maximum outside diameter can be amplified to consistent with maximum space diameter by novel platen, this just can the maximum delivered moment of torsion of lifting clutch greatly.That is, the transmission of high pulling torque can be realized in little space.Effect external diameter as selected platen is Φ 215mm, and increasing is caused Φ 228mm by platen lug design cylindrical, causes and given space interference, cannot transmit Engine torque, and traditional platen lug design as shown in Figure 7.
Novel platen is adopted not need to be greater than the space of Φ 215mm, as shown in Figure 8.
Known in identical space in conjunction with schematic diagram, high pulling torque transmission can be realized in little space.
heat produces and heat radiation aspectabove-mentioned diagram display, when space greatest diametrical dimension is determined, because novel platen maximum outside diameter is greater than traditional platen maximum outside diameter, increase the area of large of platen to a great extent, if transmit identical moment of torsion, then the heat produced during sliding wear will reduce to some extent, simultaneously, novel platen mass ratio tradition platen quality increases by 10%, thus adds the thermal capacity of platen.The thermal capacity of platen determines the radiating effect of whole clutch assembly.Therefore, use novel platen, the heat produced when effectively can reduce sliding wear, thus prevent from causing platen and friction plate ablation because the rising of assembly temperature is too fast.
other aspects, on the whole, novel platen is structurally compacter, eliminates unnecessary structure, also improves performance and life-span simultaneously.In addition, under identical space greatest diametrical dimension, as needed to transmit identical moment of torsion, novel platen external diameter is larger than traditional platen, and therefore novel platen can increase internal diameter size.Provide larger space so just to clutch drived disk assy vibration damping structure, more complicated vibration damping structure can be designed on clutch drived disk assy, realize multistage detection and other additional functions.
riveted holes size design: (Fig. 3)
H2=h × β, h are clutch compressing disc lift (1.4), and β is platen lift reserve coefficient (2-3)
H1=h3-h4-Φ+h2, h3 are that clutch space size determines installation cavity dark (14.6), and h4 is diaphragm spring thickness (2.4), and Φ is supporting ring diameter (3.2), h1 be platen cutting edge to rivet identity distance from
H5=x/2, for avoiding rivet after clutch abrasion to interfere, x is wear extent maximum value (2).
Example is transform as: for meeting the lift 1.4min of clutch assembly with DKS215 clutch, platen riveted joint face and lid riveted joint face height fall must meet 1.4*2=2.8, platen riveted joint face and platen cutting edge relative position height are 11.8mm, hole site must be square uninterruptedly in lid supporting rivet hole, simultaneously in order to ensure riveting intensity, hole is arranged in the middle of platen internal-and external diameter, and after platen-rivet, upset portion higher than pressure plate friction surfaces, can not must meet 1mmmin.The following Fig. 9 in Angular Dimension position.
