Abstract
The utility model relates to a modular structure of an oil pump assembly and a balance shaft assembly, which comprises the oil pump assembly, the balance shaft assembly and a cylinder body assembly; the oil pump assembly is arranged on the balance shaft assembly through a bolt; the module assembly is fixed in a crankcase at the bottom end of the cylinder body assembly through a bolt, and the balance shaft assembly can drive the oil pump assembly to operate while the crankshaft drives the balance shaft assembly to operate. The utility model discloses modular structure passes through the bolt with the oil pump assembly earlier and installs on balanced axle assembly, pass through the bolt fastening with the module assembly again in cylinder body bottom crankcase, when realizing the balanced axle assembly of crankshaft drive moving, balanced axle assembly passes through gear drive oil pump assembly operation, and the module assembly has realized the function that keeps off the oil board when realizing integrated oil pump assembly and balanced axle assembly, thereby the part has been cancelled and has kept off the oil board, the compactness of engine has been improved, reliability and assembly manufacturability, the degree of difficulty and the cost of arranging of engine have been reduced.
Description
Technical Field
The utility model belongs to the technical field of automobile engine, concretely relates to modular structure of oil pump assembly and balance shaft assembly.
Background
In the development of modern engines, the compactness and the modular design become important marks for evaluating the technical advancement of the engines, and how to realize the modular design of different parts while meeting the performance requirements so as to improve the compactness of the engines becomes a problem which is increasingly concerned by designers at present. In the prior engine adopting the scheme of the balance shaft assembly, the balance shaft assembly is generally independently arranged on the side surface of the cylinder body, and the oil pump assembly is generally arranged in a crankcase at the bottom end of the cylinder body and is respectively driven by an independent driving shaft, so that the engine is difficult to arrange, has a plurality of parts, is high in cost and is poor in assembly technology.
Disclosure of Invention
An object of the utility model is to the not enough of above-mentioned prior art, provide a modular structure of oil pump assembly and balance shaft assembly, solved in the engine development in the past, because the oil pump assembly is arranged in cylinder body bottom crankcase, the balance shaft assembly is arranged in the cylinder body side, and drives through solitary drive shaft respectively, leads to little discharge capacity gasoline engine structural arrangement difficulty, with high costs and the complicated technical problem of assembly process.
The utility model aims at realizing through the following technical scheme:
a modular structure of an oil pump assembly and a balance shaft assembly is composed of an oil pump assembly 1, a balance shaft assembly 2 and a cylinder body assembly 3;
the oil pump assembly 1 is arranged on the balance shaft assembly 2 through bolts to form a module assembly;
the module assembly is fixed in a crankcase at the bottom end of the cylinder body assembly 3 through bolts, and the balance shaft assembly 2 can drive the oil pump assembly 1 to operate while the crankshaft drives the balance shaft assembly 2 to operate.
The oil pump assembly 1 comprises an inner shell, an outer shell, a driving shaft, a rotor, a driven gear and the like; the balance shaft assembly 2 is composed of a balance shaft shell, a balance block, a driving gear and the like, the oil pump assembly 1 is fixed on the balance shaft shell through bolts, the driving gear of the balance shaft assembly 2 is meshed with a driven gear of the oil pump assembly 1 to drive the oil pump assembly 1 to operate, and then the module assembly is connected with the balance shaft shell through bolts and fixed on a flange face at the lower end of the cylinder body assembly 3.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses modular structure of oil pump assembly and balance shaft assembly, at first pass through the bolt with the oil pump assembly and install on balance shaft assembly, then pass through the bolt fastening with the module assembly in cylinder body bottom crankcase, when realizing the balanced shaft assembly of crankshaft drive moving, balance shaft assembly passes through gear drive machine oil pump assembly moving, and the module assembly has realized the function of oil baffle when realizing integrated oil pump assembly and balance shaft assembly, thereby the part oil baffle has been cancelled, therefore the compactness of engine has been improved, reliability and assembly manufacturability, the degree of difficulty and the cost of arranging of engine have been reduced.
Drawings
Fig. 1 is a schematic structural diagram of the oil pump assembly and the balance shaft assembly of the present invention after the modular structure is mounted on the cylinder body assembly;
fig. 2 is the structure schematic diagram of the modular structure of the oil pump assembly and the balance shaft assembly of the present invention.
Detailed Description
The invention will be further described with reference to the following examples:
as shown in fig. 1 and fig. 2, the modular structure of the oil pump assembly and the balance shaft assembly of the present invention is composed of an oil pump assembly 1, a balance shaft assembly 2 and a cylinder assembly 3;
the oil pump assembly 1 is arranged on the balance shaft assembly 2 through bolts to form a module assembly; the module assembly is fixed in a crankcase at the bottom end of the cylinder body assembly 3 through bolts, and the balance shaft assembly 2 can drive the oil pump assembly 1 to operate while the crankshaft drives the balance shaft assembly 2 to operate.
The oil pump assembly 1 is composed of an inner shell, an outer shell, a driving shaft, a rotor, a driven gear and the like (the components are of conventional structures and are not separately marked in the figures). The balance shaft assembly 2 is composed of a balance shaft housing, a balance weight, a drive gear, and the like (the above components are conventional structures and are not separately labeled in the figures). The oil pump assembly 1 is fixed on the balance shaft shell through bolts, and the driving gear of the balance shaft assembly 2 is meshed with the driven gear of the oil pump assembly 1 to drive the oil pump assembly 1 to run. And then the module assembly is connected with the balance shaft shell through bolts and is fixed on the flange surface at the lower end of the cylinder body assembly 3.
When the oil pump assembly is installed, the oil pump assembly 1 is installed on the balance shaft assembly 2 through bolts, then the module assembly is fixed in a crankcase at the bottom end of the cylinder body assembly 3 through bolts, the balance shaft assembly 2 drives the oil pump assembly 1 to operate while the crankshaft drives the balance shaft assembly 2 to operate, and the module assembly simultaneously realizes the function of an oil baffle plate, so that the oil baffle plate is cancelled; the mechanism realizes the modular design of the oil pump assembly 1 and the balance shaft assembly 1, and integrates the function of an oil baffle plate; the compactness, the reliability and the assembly manufacturability of the engine are improved, and the arrangement difficulty and the cost of the engine are reduced.
