Embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 2-4, Fig. 2 provides the structural representation of a kind of specific embodiment of cylinder head for the utility model; Fig. 3 is the schematic internal view of Fig. 2; Fig. 4 is that the B-B of Fig. 3 is to sectional view.
Cylinder head in this embodiment, is provided with air flue, and cylinder head is entity, and air flue is directly opened in the inside of cylinder head, and as shown in Figure 3,4, air flue specifically comprises intake duct 22a and air outlet flue 21a.The base plate of cylinder head can arrange the suction valve cone 22 being communicated with intake duct 22a, the exhaust valve seat 21 being communicated with air outlet flue 21a, be used for connecting exterior line, to realize air inlet and exhaust, two suction valve cones 22 and two exhaust valve seats 21 are specifically set in figure, certainly, according to the actual requirements, accommodation can be made in the number of suction valve cone 22 and exhaust valve seat 21 and position.
Cylinder head comprises base plate, when the air flue of cylinder head inside extends to base plate place, takes round-corner transition to be connected with base plate.In the present embodiment, at the round-corner transition link position of base plate and air flue, be provided with stiffening rib 26, as shown in Figure 3.Cylinder head is provided with the oil sprayer bushing mounting hole 24 that oil sprayer bushing is installed, and the link position of air flue and base plate is near mounting hole of oil sprayer 24, and stiffening rib 26 is located at oil sprayer bushing air flue place around, as shown in Figure 4.
The setting of stiffening rib 26 can avoid casting process to crack, thereby improves the intensity of air flue and back plate connections, avoids cylinder head to lose efficacy.
Further, base plate has for cooling water and flows into the upper water hole 23 of cylinder head inside, and upper water hole 23 forms by boring, as shown in Figure 2.Compared to blowhole structure, the upper water hole 23 that boring forms can guarantee its machining accuracy, thereby guarantees the relative position in head gasket water sealing aprons and upper water hole 23, avoids water sealing aprons and upper water hole 23 misplace and lost efficacy, and also can realize the accurate control of streamflow simultaneously.
Can also make further optimization to the layout in upper water hole 23.
Please refer to Fig. 5, Fig. 5 is the flow path schematic diagram of cylinder head internal cooling water in Fig. 4.
Can understand in conjunction with Fig. 2, the number in upper water hole 23 is multiple, and is divided into air inlet side and the exhaust side of base plate, and upper water hole 23 numbers of exhaust side are greater than upper water hole 23 numbers of air inlet side.In Fig. 2, for upper water hole 23,23, two, 5 upper water holes is set, be positioned at air inlet side, three upper water holes 23 are positioned at exhaust side.
The circulating path of cylinder head cooling water is as follows:
Cylinder head inside is provided with upper water cavity 282, lower water cavity 281 and water outlet 29, cooling water enters lower water cavity 281 from the upper water hole 23 at cylinder head base plate place, then entering ridge area A (is the outer convex domain between intake duct 22a and air outlet flue 21a, as shown in Figure 3), through the gap of oil sprayer bushing surrounding, enter upper water cavity 282 again, finally by the water outlet 29 being communicated with upper water cavity 282, flow out, water outlet 29 can be located at the top board (relative with base plate) of cylinder head and locate.
In addition, the water outlet 29 of cylinder head can be positioned at the upside of air outlet flue 21a, as shown in Figure 5.So, can farthest utilize the temperature of cooling water reduction exhaust side, further guarantee the intensity of cylinder head.For ease of arranging and make full use of cooling water, as mentioned above, water outlet 29 is located at the top board place of cylinder head.
Please refer to Fig. 6, Fig. 6 is the schematic diagram of oil sprayer bushing mounting hole in Fig. 4.
Cylinder head is provided with oil sprayer bushing mounting hole 24, and so that oil sprayer bushing to be installed, oil sprayer bushing mounting hole 24 is generally positioned at the middle part of cylinder head.Take Fig. 6 as visual angle, the head of oil sprayer bushing packs this oil sprayer bushing mounting hole 24 down into, and the position that its head is installed is the bottom outlet 241 of oil sprayer bushing mounting hole 24.In the present embodiment, can annular ditch groove 241a be set in the sidewall of bottom outlet 241.Oil sprayer bushing can be pressed into and be riveted in oil sprayer bottom outlet 241, arranges after annular ditch groove 241a, press-fits the better effects if of riveted joint, can effectively prevent that oil sprayer bushing is loosening, depart from.
On this basis, the number of annular ditch groove 241a can be multiple, and is arranged in vertically the sidewall of bottom outlet 241, so, can further improve the effect that presses.
For the various embodiments described above, can lubricating oil return hole 27 be set in the air inlet side of cylinder head, as shown in Figure 3.Generally, cylinder head is connected with rocking arm, and rocking arm has the push-rod hole that is communicated with cylinder head inside, and in cylinder head, mobile lubricant oil can flow out through the push-rod hole of rocking arm.But, when the position of push-rod hole is higher, may produce the problem that lubricant oil cannot reflux smoothly, such as, for the V-type engine under working state (paired engine), its cylinder head is 45 degree inclination angles, and push-rod hole is positioned at high-end, the lubricant oil flowing out from rocking arm is not easy to reflux.
In the air inlet side of cylinder head, process behind the lubricating oil return hole 27 being communicated with internal lubrication oil duct, for the cylinder head (than V-type engine described above) of inclination work, air inlet side is in lower position, and lubricant oil can flow out smoothly through this lubricating oil return hole 27.Can on the body of motor, process corresponding oil leab, be communicated with lubricating oil return hole 27, the lubricant oil in cylinder head finally can be back to oil sump through engine body.
Except above-mentioned cylinder head, the utility model also provides a kind of motor, comprises the cylinder head of cylinder and capping cylinder, and cylinder head cover cylinder forms firing chamber, and described cylinder head is the cylinder head described in above-mentioned arbitrary embodiment.Because above-mentioned cylinder head has above-mentioned technique effect, the motor with this cylinder head also has identical technique effect.
Above a kind of motor provided by the utility model and cylinder head thereof are all described in detail.Applied specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
