Description
Technical Field
The utility model relates to an engine parts technical field specifically is a compact general lightweight engine structure.
Background
In a traditional engine structure, half of a gear chamber is generally designed to be integrated on a cylinder block through integral casting with the cylinder block, and the other half of the gear chamber is assembled with a flywheel shell to form a complete gear chamber, and the defects are as follows: (1) the gear chamber cover plate integrally cast with the cylinder block needs to consider the draft angle, so the wall thickness is thicker, and the cylinder cover is completely supported on the cylinder block, which causes the cylinder block and the cylinder cover to be lengthened in the axial direction, so the length of the whole machine is increased; (2) a complete gear chamber is formed by half of each of the cylinder body and the flywheel housing, and the cylinder body and the cover plate of the gear chamber are of cast iron structures, so the weight of the whole machine is heavy; (3) the cylinder block casts interfaces such as an air compressor injection pump, when interfaces such as the injection pump are changed, the cylinder block needs to be changed into a mold, and the universality is poor.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned current defect, the utility model provides a compact general lightweight engine structure can effectively utilize the space, reduces engine axial length to reduce the dead weight, improved the suitability of complete machine.
In order to achieve the purpose, the technical scheme of the utility model is as follows:
a compact, universal and lightweight engine structure comprises an air cylinder body, an air cylinder cover, a flywheel shell, a gear chamber cover plate and a gear chamber, wherein the air cylinder body and the gear chamber are arranged in a split manner; the surface of the flywheel shell opposite to the end part of the cylinder body radially extends out of the side face of the cylinder body, a cavity is formed on the surface extending out of the side face of the cylinder body, and a gear chamber cover plate is connected with the cavity to form the gear chamber.
Specifically, the flywheel shell is of a cast aluminum structure.
Specifically, an air compressor connector and an oil pump connector are arranged on the gear chamber cover plate.
The utility model has the advantages that:
1. the flywheel housing is fixed with the cylinder cover, the mode of installing the gear housing cover plate is adopted, the condition that the gear housing cover plate and the cylinder body are cast into a whole in the prior art is changed, then the assembling mode of the flywheel housing is installed, the cylinder cover only spans over the cylinder body and the flywheel housing, and under the condition that the installation steps are not complicated, shorter length is obtained between the flywheel housing and the cylinder body, the redundant weight part of the cylinder cover is reduced, the space can be effectively utilized, the axial length of an engine is reduced, and therefore the weight of the engine is reduced.
2. Because the gear chamber cover plate is not integrated with the cylinder body, the problems of pattern drawing inclination and the like do not need to be considered, the thickness of the gear chamber cover plate can be reduced, and the dead weight is light; if there is change such as air compressor machine interface oil pump interface, only need to process again gear chamber apron can, the commonality is good, has solved among the prior art gear chamber apron and cylinder block integration, need consider the draft inclination to and wall thickness and intensity etc. lead to the problem that the dead weight rises.

Detailed Description
In order to explain the technical content, the achieved objects and the effects of the present invention in detail, the following description is made in conjunction with the embodiments and the accompanying drawings.
As shown in fig. 1-2, the utility model provides a compact general lightweight engine structure, which comprises a cylinder block 1, a cylinder head 2, a flywheel housing 3, a gear chamber cover plate 4 and a gear chamber 5, wherein the cylinder block 1 and the gear chamber 5 are arranged separately, the upper end surface of the cylinder block 1 is connected with the lower end surface of the cylinder head 2, one end of the cylinder head 2 extends out of the end part of the cylinder block 1, and the lower end surface of the cylinder head is connected with the upper end surface of the flywheel housing 3; wherein, the surface of the flywheel housing 3 opposite to the end of the cylinder block 1 radially extends out of the side surface of the cylinder block 1, a cavity is formed on the surface extending out of the side surface of the cylinder block 1, and a gear chamber cover plate 4 is connected with the cavity to form a gear chamber 5.
The utility model discloses the installation sketch map is shown in fig. 2, it is fixed with cylinder head 2 through bell housing 3, adopt the mode of installation gear chamber apron 4, gear chamber apron 4 among the current has been changed and cylinder block 1 casts as an organic wholely, then install the assembly mode of bell housing 3 again, make cylinder head 2 only stride across cylinder block 1, bell housing 3, under the condition that the installation step is not complicated, shorter length has been obtained between bell housing 3 and the cylinder block 1, reduce the unnecessary weight part of cylinder head 2, can effectively utilize the space, reduce engine axial length, thereby engine weight has been reduced.
As the preferred scheme of this embodiment, the flywheel housing 3 adopts the cast aluminum structure, further reduces the complete machine weight.
As the preferred scheme of this embodiment, be provided with air compressor machine interface 6 and oil pump interface 7 on the gear chamber apron 4, if air compressor machine interface 6 oil pump interface 7 etc. changes, only need to process gear chamber apron 4 again can, the commonality is good.
Although the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that modifications and improvements can be made thereto. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
