Description
Technical field
This utility model relates to auto-parts technical field, more specifically, particularly to clutch compressing disc and a kind of novel clutch of a kind of band radiation air wing.
Background technology
In dry friction type automobile clutch cap assembly, platen is as the part of quality maximum in casting (HT or QT) part, and its single-piece quality accounts for the 2/3 of clutch assembly quality.Platen is transmitting owing to the sliding friction power loss produced from--conjunction action with clutch plate rubbing surface high frequency time is general the biggest in moment of torsion, and this work of slipping loses 100% ground and is reflected in friction heat consumption.
Wherein, passenger car is on urban pavement, and due to traffic congestion, average every kilometer of clutch number of times is more than five times；Owing to there is serious overload condition in commercial truck, although long-distance highway transportation, road conditions still can, but clutch to undertake torsion pass load excessive, often produce " skidding " phenomenon.The disadvantageous applying working condition of both the above, all can produce clutch assembly overheated, and clutch overheat current status is the most common to be had: platen overheated " burning orchid " " face table mirror " " cracking " lost efficacy；Clutch plate friction plate carbonization " scaling loss "；Engine flywheel " face table ablation ".Any of the above fault mode occurs all to make clutch scrap so that automobile cannot normally travel.
Getting rid of the use and maintenance reasons such as misoperation, say with regard to the face of clutch configuration own, the raising of platen heat absorption capacity (heat resistance in other words) is one of important channel solving clutch heating.The temperature capacity of cast iron is higher in metal material, so clutch compressing disc the most all uses gray iron or ductile cast iron material manufacture.Under material permanence condition, the thermal capacity of clutch to be increased, only a kind of method, it is simply that increase platen diameter or thickness, strengthen clutch quality.In clutch, the increase of platen diameter can be limited by arrangement space, increases platen thickness and then can be limited by clutch assembly physical dimension and rotary inertia；Sum it up, it is very limited amount of for strengthening, increase the weight of platen size solving problem.It addition, car or truck, car load all has strict restriction, so it is impracticable for attempting to increase clutch quality to solve problem overheated, ablation to the rotary inertia of clutch assembly and the motility of operation response.
At present, frequently with the way opening air holes on the clutch case (shell) in cap assembly in clutch designs, offer a kind of method that air vent is passive heat radiation, although having certain radiating effect, but there is a serious problem in device, that is: in clutch assembly (cap assembly and clutch drived disk assy are combined into a pair), lid (shell) is the element uniquely undertaking thrust, its bending resistance shape rigidity there are pole strict requirements, if perforate is excessive or too much, then loss of rigidity will increase, thrust declines the most rapidly, the reserve coefficient (β=1.5～2.5) of torsion pass is not enough, in rotating carrying, " skidding " can occur.If there is skidding, add the most again " heating " of clutch, cause and aforementioned the same problem.
