The model utility content
The utility model mainly is that the camshaft-bearing cap and the installation precision between the cylinder head cover that exist in the solution prior art are not high, can not guarantee the good sealing property between cylinder head cover and the cylinder cap, make motor produce bad vibration easily, influence engine performance, and number of spare parts is more, be unfavorable for the problem of assembling, a kind of integral car engine cylinder head cover is provided, this cylinder head cover not only can be simplified number of spare parts more, and can better guarantee the sealing between cylinder head cover and the cylinder cap, improve engine performance.
In order to solve the problems of the technologies described above, the utility model has adopted a kind of like this integral car engine cylinder head cover, this cylinder head cover comprises some mounting hole of oil sprayer and some bolt mounting holes, between the described mounting hole of oil sprayer outside and two inner side surfaces of described cylinder head cover, be respectively equipped with stiffening rib with described cylinder head cover one, described stiffening rib is parallel to the end face of cylinder head cover, the camshaft bearing lid of coaxial mutually one is set on the stiffening rib of homonymy respectively, the camshaft bearing lid of two one is set respectively at two ends, described cylinder head cover bottom surface, and the camshaft bearing lid at two ends, described cylinder head cover bottom surface covers coaxial setting with the camshaft bearing on the stiffening rib.Between the mounting hole of oil sprayer outside and two inner side surfaces of cylinder head cover, be provided with stiffening rib, and the camshaft bearing that one is set on stiffening rib covers, the rigidity and the intensity of cylinder head cover have so not only been improved, and integrated camshaft bearing lid, reduced the number of spare parts of assembling, optimize the processing technology and the assembly technology of cylinder head cover, reduced the manufacturing cost of complete machine.Sealing function and camshaft bearing lid with cylinder head cover is integrated into a part in addition, both played the effect of sealing oil gas, and the effect of fixed support is provided to camshaft again, reduces the assembling that number of spare parts helps storehouse logistics management and motor simultaneously.
As preferably, the strip groove that is parallel to described camshaft bearing lid axial direction is set on described stiffening rib, described strip groove is positioned at the both sides of described camshaft bearing lid.Both sides at the camshaft bearing lid are provided with strip groove, can cushion the vibration of camshaft to a certain extent, improve engine performance.
As preferably, on the described mounting hole of oil sprayer end face annular seal groove is set.Seal groove is used to install seal ring, and the sealing cylinder head cover improves the sealability between cylinder head cover and the cylinder cap.
As preferably, positioning hole is set at diagonal angle, described cylinder head cover bottom surface.So not only be convenient to install cylinder head cover, and can guarantee the assembly precision of cylinder head cover on cylinder cap, and then the degree of adaptability between the raising camshaft bearing lid.
As preferably, in the camshaft bearing lid inboard of described cylinder head cover bottom surface one end the camshaft thrust surface is set, in the camshaft bearing lid semi circular surface of the other end Bearing Installation groove is set.The design of camshaft thrust surface is inboard at the camshaft bearing lid of cylinder head cover one end, can guarantee the axially locating of camshaft, and cover at the camshaft bearing of the other end and to be provided with the Bearing Installation groove that design need not be considered thrust surface and Bearing Installation groove separately like this, technology is simple, reduces cost.
As preferably, between the described mounting hole of oil sprayer outside, the one stiffening rib is set.The rigidity of so further raising cylinder head cover is of value to the vibration and the noiseproof feature that improve motor.
The beneficial effects of the utility model are integrated camshaft bearing lids on the cylinder cover cap, so not only reduced the number of spare parts of assembling, help the assembling of storehouse logistics management and motor, the processing technology and the assembly technology of cylinder head cover have been optimized, reduced the manufacturing cost of complete machine, and the sealing function and the camshaft bearing lid of cylinder head cover are integrated into a part, had both played the effect of sealing oil gas, the effect of fixed support is provided to camshaft again.
