Description
Technical Field
The utility model relates to a technical field of engine, more specifically say, the utility model relates to a strenghthened type oil baffle.
Background
In the prior art, as shown in fig. 1, a cylinder block 1 and a main bearing cap 2 are of an independent structure, and an oil baffle plate 3 is mounted on an oil pan. With the continuous strengthening of the engine, the explosion pressure is larger and larger, the strength and the rigidity of the independent structure cannot meet the requirements, and the reliability and the NVH of the engine are adversely affected. For strength, the cylinder block 1 and the main bearing cap 2 are connected by two reinforcing plates 8, and then the oil deflector 3 is screwed to the main bearing cap 2 by bolts 6,7, 9. The structure has the advantages of more parts, difficult management, more production and assembly processes and high cost.
SUMMERY OF THE UTILITY MODEL
For solving the above-mentioned technical problem that exists among the prior art, the utility model aims to provide a strenghthened type oil baffle.
The reinforced oil baffle plate comprises a first baffle, a second baffle and a third baffle which are integrally formed, wherein the first baffle, the second baffle and the third baffle are sequentially and adjacently arranged; the first baffle, the second baffle and the third baffle are all of curved surface structures, and oil falling holes are formed in the lowest points of the curved surfaces; short bolt bosses are arranged at four corners of the first baffle and the third baffle, and two long bolt bosses are respectively arranged on the middle sections of two side edges of the first baffle and the third baffle; strip-shaped ribs are arranged on the surfaces of the first baffle, the second baffle and the third baffle, which are opposite to the cylinder body; and latticed ribs are arranged on the surfaces of the first baffle plate, the second baffle plate and the third baffle plate, which are opposite to the oil pan.
Wherein, the oil baffle is of a casting structure.
Wherein, the thickness of the oil baffle plate is 3-4 mm.
Compared with the prior art, the utility model discloses a strenghthened type oil baffle has following beneficial effect:

Detailed Description
The reinforced oil baffle of the present invention will be further described below with reference to specific embodiments to help those skilled in the art understand the technical solution of the present invention more completely, accurately and deeply.
Example 1
As shown in fig. 2-3, the reinforced oil baffle 10 of the present invention includes a first baffle 11, a second baffle 12 and a third baffle 13, which are integrally formed, wherein the first baffle 11, the second baffle 12 and the third baffle 13 are sequentially and adjacently disposed; and the first baffle 11, the second baffle 12 and the third baffle 13 are all curved surface structures, and oil falling holes 15 are provided at the lowest points of the respective curved surfaces, strip-shaped ribs 16 are provided on the surfaces of the first baffle 11, the second baffle 12 and the third baffle 13 opposite to the cylinder block 20, and grid-shaped ribs 19 are provided on the surfaces of the first baffle 11, the second baffle 12 and the third baffle 13 opposite to the oil pan (see fig. 5). Short bolt bosses 18 are arranged at four corners of the first baffle plate 11 and the third baffle plate 13, and two long bolt bosses 17 are respectively arranged on the middle sections of two side edges of the first baffle plate 11 and the third baffle plate 13. The oil baffle is of a casting structure, is made of aluminum alloy and has the thickness of 3-4 mm.
There are 2 rings of bolts in the strenghthened type oil baffle 10 of this embodiment, and the outer lane is installed on the cylinder body through 8 short bolts, and the inner circle is installed on the main bearing cap through 8 long bolts. The oil baffle plate is provided with grid-shaped reinforcing ribs, so that the oil baffle plate has good structural strength.
As shown in fig. 4-5, the outer ring is mounted to cylinder block 20 by 8 short bolts 40 and the inner ring is mounted to main bearing cap 30 by 8 long bolts 50. The design structure connects the cylinder body 20 and the main bearing cap 30 together through the oil baffle plate 10, so that the structural strength and rigidity of the engine are improved, and the reliability and NVH performance of the engine are improved. The design of oil baffle plate has 3 oilholes 15 that fall, guarantees under the whole car carrying state, and the oilhole 15 that falls is in the minimum, and machine oil can fall in the oil pan smoothly. The oil baffle cylinder body side is designed with a strip rib 16, the oil bottom shell side is designed with a grid reinforcing rib 19, and the structural strength of the oil baffle can be well improved.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial modifications are possible within the protection scope of the present invention as long as the method concept and technical solution of the present invention are adopted.
