Problems solved by technology
Since the "series" integrated structure has a large axial length and is arranged between the frame and the front axle of the car, it is not suitable for models with a small gap between the frame and the front axle
At the same time, the "series" integrated structure increases development and manufacturing costs, and the separation layer separating the vacuum chamber from the oil pump chamber is prone to poor sealing, and there is a hidden danger of oil leaking into the vacuum chamber

An integrated structure of an oil pump and a vacuum pump of an automobile engine aims at solving the problem that an protruding portion of a vehicle-mounted engine interferes with an automobile body engine room. The integrated structure is fixed at the lower end of an engine block and composed of an oil pump assembly, a vacuum pump assembly and a transmission structure. The oil pump assembly and the vacuum pump assembly are arranged parallelly and integrated in parallel connection mode, and the transmission structure is arranged between an engine crankshaft and the oil pump assembly and the vacuum pump assembly. The integrated structure has the advantages of being compact in structure, stable in performance, good in adaptability and low in manufacture cost. The integrated structure can guarantee reliable operation of the oil pump and the vacuum pump of the engine, is favorable for carrying of the engine in the automobile body engine room, and meets general arrangement requirements of an automobile.
Description
technical field [0001] The invention relates to an integrated structure of an engine oil pump and a vacuum pump, belonging to the technical field of engines. Background technique [0002] Generally, the engine oil pump of an automobile is arranged at the lower end of the cylinder block and inside the oil pan, and is driven by the crankshaft through a chain; the engine vacuum pump is usually arranged on the cylinder head and driven by the camshaft. Since the vacuum pump occupies a large space and is located at the front or rear of the engine, it is a protruding part of the engine. When the engine is installed, the vacuum pump often interferes with the engine room, which cannot meet the requirements for the engine to be mounted on the car body. [0003] In response to the above problems, some automobile manufacturers have adjusted the arrangement of the engine oil pump and the vacuum pump, integrating the vacuum pump and the oil pump in a "series" manner, sharing a shell with ...
