Abstract

The invention discloses a transmission structure of an oil pump, which comprises the oil pump and a balance shaft system. The oil pump comprises an oil pump rotor shaft, the balance shaft system comprises a balance shaft driving gear and a balance shaft driving shaft, the oil pump rotor shaft is connected with the balance shaft driving shaft through a driving shaft, and the balance shaft driving shaft is provided with the balance shaft driving gear connected with a chain wheel system. The transmission structure of the oil pump effectively connects a balance shaft and the oil pump in a driving mode through a hexagonal shaft, well and effectively composites the transmission of the balance shaft and the oil pump, can ensure the oil pump and the balance shaft to simultaneously and reliably work by only adopting one set of chain wheel driving system, and is simple in structure and convenient in assembly, disassembly and maintenance. Simultaneously, due to the fact that one set of chain wheel driving system is reduced, development cost is also reduced.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a transmission structure of an oil pump. Background technique [0002] The oil pump is one of the core parts of the engine lubrication system and plays a decisive role in the entire engine lubrication system. It provides sufficient pressure and flow of oil for the entire engine, so that the lubricating oil circulates continuously in the lubrication system to ensure that every One friction part is adequately lubricated, protecting the associated pressure-bearing parts from damage. [0003] At present, the arrangement of the oil pump in the engine lubrication system mainly has two structures: directly driven by the crankshaft and driven by a chain. Since the oil pump directly driven by the crankshaft is arranged at the outer end of the cylinder, it not only has high requirements for sealing, but also because it is directly connected to the crankshaft. Connection, the drivin...
