Description
Technical field
The utility model relates to the camshaft positioning device of motor car engine, specifically a kind of camshaft supporting box.
Background technique
The cam shaft arrangement mode of present most popular motor car engine is exactly the camshaft overhead type.In this layout, camshaft-bearing cap cooperates with cylinder head for camshaft and provides support and lubricate.
Motor for camshaft overhead structure, camshaft-bearing cap generally has two class formations: 1, monomer-type camshaft-bearing cap, the corresponding camshaft of bearing cap supports, perhaps assembled camshaft bearing cap, and the corresponding two or more camshafts of bearing cap support; 2, one-piece camshaft bearing cap, one-piece camshaft bearing cap cover all camshafts and support.For last class, the volume of camshaft-bearing cap is little, and is easy to assembly, but shortcoming is weak, and the oilhole that needs to process complexity on the cylinder cap provides lubricant oil for camshaft; For back one class, the structural strength height of camshaft-bearing cap, solid and reliable to compressing of camshaft, but shortcoming is thick and heavy and cylinder head is an external sealed, to processing and matching requirements height, and the sealing difficulty.
The sealers that adopt seal more between existing one-piece camshaft bearing cap and cylinder head, and sealing surface contacts with extraneous, to being sealed with high requirement, because the uniformity of gluing technology is difficult to control, cause engine motor oil to leak easily, and the machine oil loss is fast.In addition, owing to be external sealed, relatively stricter to connecting camshaft-bearing cap with the clamping bolt arrangement requirement of cylinder head, and camshaft bearing covers and needs the increase leak-proof arrangement, and these have all increased the complexity and the leakage of oil risk of one-piece camshaft bearing cap structure significantly.
The model utility content
The purpose of this utility model is to provide a kind of camshaft supporting box, and it can be reliably for camshaft provides lubricated, and good airproof performance.
For achieving the above object, the utility model adopts following scheme: the camshaft supporting box, it includes integrally-built camshaft-bearing cap and cylinder head, camshaft bearing covers and has one group of spark plug mounting hole, the both sides that are positioned at spark plug mounting hole on the camshaft-bearing cap inner side surface respectively are provided with one group and are the planar groove of semicolumn, correspondence has one group of spark plug mounting hole on the cylinder head, the both sides that are positioned at spark plug mounting hole on the cylinder head upper-end surface are also corresponding respectively to be provided with one group and to be the planar groove of semicolumn, have two at the edge of cylinder head front portion and be half-terete gap, each gap respectively with one group of groove alignment, camshaft-bearing cap and cylinder head pass through Bolt Connection, on the inner side surface of camshaft-bearing cap, have the oil duct of two depressions, every oil duct is communicated with each groove that is in each spark plug mounting hole homonymy respectively, one of them side of every group of groove has oil input channel on cylinder head, and the oil duct of this oil input channel and camshaft-bearing cap is connected.
By such scheme as seen, by the oil duct of two depressions being set on the inner side surface of camshaft-bearing cap and oil input channel being set on cylinder head, it is lubricated to guarantee that camshaft obtains reliably, and camshaft-bearing cap is with after cylinder head connects, the good airproof performance of oil duct on the camshaft-bearing cap.In addition,, need not process special oilhole more thereon on the inner side surface of camshaft-bearing cap, simplify the structure of camshaft-bearing cap by the oil duct of two depressions is set.
The utility model is rational in infrastructure, reliable, its camshaft-bearing cap designs simplification, and in use the oil leak probability is little.

Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2, have one group of spark plug mounting hole 2 on the camshaft-bearing cap 1 of the present utility model, the both sides that are positioned at spark plug mounting hole 2 on camshaft-bearing cap 1 inner side surface respectively are provided with one group and are the planar groove of semicolumn 3, have the oil duct 4 of two depressions on the inner side surface of camshaft-bearing cap 1, every oil duct 4 is communicated with each groove 3 that is in each spark plug mounting hole 2 homonymy respectively.
Referring to Fig. 3, Fig. 4, correspondence has one group of spark plug mounting hole 7 on the cylinder head 6, the both sides that are positioned at spark plug mounting hole 7 on cylinder head 6 upper-end surfaces are also corresponding respectively to be provided with one group and to be the planar groove of semicolumn 8, have two at the edge of cylinder head 6 front portions and be half-terete gap 11, each gap 11 is aimed at one group of groove 8 respectively, and one of them side of every group of groove 8 has oil input channel 9 on cylinder head 6.
Referring to Fig. 4, the Liang Jiaochu in the zone that contacts with camshaft-bearing cap on the upper-end surface of cylinder head 6 is fixed with locating stud 9.Referring to Fig. 1, corresponding two positioning holes 5 that have on the inner side surface of camshaft-bearing cap.By locating stud 9 and positioning hole 5, can guarantee that the location when camshaft-bearing cap 1 connects with cylinder head 6 is reliable.
