Description
Technical field
The utility model relates to a kind of valve chamber cover and pad, is mainly used on the motor.
Background technique
Valve chamber cover is many with the sheet metal impact briquetting, because sheet metal plasticity is good, punching press and welding are all simpler, and product cost is lower, but steel-sheet rigidity is bad, and is stressed yielding, does valve chamber cover with this, and sealability is relatively poor.
Existing valve chamber cover, to shown in Figure 9, the hermetic unit of this cover cap is distributed with incoherent stiffening rib 1 as Fig. 1, can play the effect of compress gasket when assembling simultaneously.But steel-sheet rigidity is relatively poor, and these incoherent stiffening ribs cause under situation about tighting a bolt the enhancing DeGrain of cover cap rigidity, and stiffening rib breakthrough place easy deformation can not form coherent sealing surface during compress gasket.Cover cap has flange on the edge, shears out swallow-tail form draw-in groove 2 and draw-in groove 5 on the flange, and the triangle claw 6 of pad cooperates with it during assembling, the retaining washer position.The compensatory deficiency of pad, cover cap distortion place easily and junction plane peel off, all on this, cause the appearance of leakage of oil problem.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned deficiency at existing valve chamber cover, do not increasing cost, existing structure and material are not being done under the situation of big change, a kind of valve chamber cover and pad of simplifying assembly technology and improving sealability is being provided.
For solving the problems of the technologies described above, the utility model provides a kind of valve chamber cover, this cover cap cooperates with rubber sheet gasket and is used for valve cage is sealed, cover cap is provided with the closed draw-in groove that holds the pad bottom at the position that contacts with pad, the sectional shape of the sectional shape of closed draw-in groove and pad bottom matches.
Simultaneously, the utility model provides a kind of pad that is used for valve chamber cover, and the sectional shape of the closed draw-in groove that holds the pad bottom that is provided with on the sectional shape of this pad bottom and the cover cap matches.
Further, the utility model provides a kind of cyclinder head cover cap assemblies, comprise valve chamber cover and rubber sheet gasket, cover cap is provided with the closed draw-in groove that holds the pad bottom at the position that contacts with pad, and the sectional shape of the sectional shape of closed draw-in groove and pad bottom matches.
The pad both sides of this assembly are provided with equally distributed projection, chucking pad when being used in the pad bottom is contained in above-mentioned draw-in groove; The position that pad contacts with valve cage is provided with the closing seam line; Pad is provided with a plurality of bolts hole, and pad is being provided with bolt washer with each bolt hole junction.
Compare with existing valve chamber cover and pad, above-mentioned improved cover cap sets up the draw-in groove of complete closure at the hermetic unit of cover cap, can be one time punching molded with cap body; Draw-in groove shape and pad bottom coincide, and the restriction pads placement is played good effect; Gasket body is a rubber, and the both sides projection that evenly distributes can make the pad chucking when assembling, and the pad upper surface is provided with closed potted line, is provided with bolt washer with the pad one with the bolt contact segment.
The advantage of improved cyclinder head cover cap assemblies is: assembling is simple, and it is convenient to change; Save the comparatively complicated cutting operation of flange and shape, simplified stamping process, improved stock utilization, reduced cost of production; Draw-in groove is closed, not only better with the Percent of contact area of pad fully, and the position that also can play the restriction pad can be used as the rigidity that stiffening rib strengthens cover cap simultaneously, makes cover cap stressed more even under the situation that bolt is tightened everywhere, reduces distortion; The closing seam line of pad has improved the compensation performance of pad; Stressed at most, maximum bolt and the pad junction of deformation extent be provided with bolt washer, reduced the probability that pad ftractures herein.By evidence, make the sealing of engine valve chamber cover cap improve 100 times.
