Abstract
The utility model discloses a vehicle engine cylinder head; a plurality of bolt holes (1) are arranged on the cylinder head (4) to fasten the cylinder (4); an oil duct (2) is arranged on the cylinder head (4) which is communicated with the bolt holes (1). Compared with prior art, the utility model achieves the goal of lubricating the valve train alike by transmitting lubricating oil through the clearance between fastening bolts and bottom outlet, in the meantime, decreases machining difficulty and improves the structural strength of the cylinder head.
Description
Technical field
The utility model relates to automobile chassis, and more particularly, the utility model relates to a kind of automobile engine cylinder head.
Background technique
At present, on the cylinder cap structural design of motor car engine, special main oil gallery is arranged, be lubricated the transmission of oil, reach the purpose of lubricated distribution device.
The shortcoming of this design mainly contains two aspects: the one, carry out the processing of main oil gallery separately, and bring difficulty for the processing of cylinder cap; The 2nd, this main oil-hole of offering separately causes the decline of cylinder cap intensity.
The model utility content
Problem to be solved in the utility model provides a kind of automobile engine cylinder head, its objective is the intensity of simplifying the cylinder cap structure and improving cylinder cap.
To achieve these goals, this automobile engine cylinder head that the utility model provides is provided with the cylinder head bolt hole that fastening cylinder cap is used on cylinder cap, establishes horizontal oil duct and connect with described cylinder head bolt hole on cylinder cap.
Described horizontal oil duct is vertical perforation with described cylinder head bolt hole, and type of tamper evidence is established in the aperture that leads to the cylinder cap outside, and laterally oil duct communicates with oblique oil duct, and tiltedly another aperture of oil duct communicates with lubricated distribution device.
The technique scheme that the utility model adopted compared with prior art, the gap that utilizes cylinder cap to tighten between bolt and the bottom outlet is lubricated oily transmission, reach the purpose of lubricated distribution device equally, and reduced the difficulty of processing of cylinder cap, improve the structural strength of cylinder cap simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structure cross-sectional schematic in front of the present utility model;
Fig. 2 is the structure cross-sectional schematic of side of the present utility model.
Number in the figure is: 1, cylinder head bolt hole, 2, horizontal oil duct, 3, oblique oil duct, 4, cylinder cap, 5, horizontal oil duct type of tamper evidence.
Embodiment
Shown in the structure cross-sectional schematic of the structure cross-sectional schematic in Fig. 1 front of the present utility model and Fig. 2 side of the present utility model, the utility model is a kind of automobile engine cylinder head, be provided with the cylinder head bolt hole 1 that fastening cylinder cap is used on cylinder cap 4, its original purpose and purposes have been the effects of fastening cylinder cap.
The scheme that the utility model is taked is: establish horizontal oil duct 2 and connect with described cylinder head bolt hole 1 on cylinder cap 4.Utilize the clamping bolt and the transmission of the gap between the cylinder bolt bottom outlet lubricant oil of cylinder cap 4, needn't design cylinder cap main oil gallery structure separately.Cylinder head bolt hole 1 communicates with oil circuit on the cylinder body again, to obtain the input of lubricant oil.
In order to realize that lubricant oil presses needed direction and flow, as can be seen from Figure 2, laterally oil duct 2 is vertical perforation with described cylinder head bolt hole 1, is more convenient for like this processing.Horizontal oil duct type of tamper evidence 5 is established in the aperture that leads to the cylinder cap outside, forces lubricant oil to flow to the oblique oil duct 3 that communicates with it from horizontal oil duct 2 and communicates, and tiltedly another aperture of oil duct 3 communicates with lubricated distribution device.At last, lubricant oil flows into distribution device.
The basic ideas of the technique scheme that adopts are that the gap that utilizes cylinder cap to tighten between bolt and the bottom outlet is lubricated oily transmission, reach the purpose of lubricated distribution device equally, have not only reduced the difficulty of processing of cylinder cap, and have improved the structural strength of cylinder cap again.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
Claims (2)
1, a kind of automobile engine cylinder head is provided with the cylinder head bolt hole (1) of fastening cylinder cap (4) usefulness on cylinder cap (4), it is characterized in that: establish horizontal oil duct (2) and connect with described cylinder head bolt hole (1) on cylinder cap (4).
2, according to the described automobile engine cylinder head of claim 1, it is characterized in that: described horizontal oil duct (2) is vertical the perforation with described cylinder head bolt hole (1), horizontal oil duct type of tamper evidence (5) is established in the aperture that leads to the cylinder cap outside, laterally oil duct (2) communicates with oblique oil duct (3), and tiltedly another aperture of oil duct (3) communicates with lubricated distribution device.
