Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0031] The following will refer to figure 1 and figure 2 The oil pump 100 of the embodiment of the present invention will be described in detail in conjunction with the embodiments. The oil pump 100 is connected to the engine. For example, an oil pump sprocket can be installed at one end of the drive shaft 10, so that the engine can drive the oil pump 100 to work through the oil pump sprocket.

[0032] Such as figure 1 As shown, the oil pump 100 according to the embodiment of the present invention may include: a driving shaft 10, a driven shaft 20 and a motor, the driving shaft 10 is fixedly provided with a driving gear a, and the driven shaft 20 is provided with a driven gear b, The driven gear b meshes with the driving gear a, and the motor drives the driven shaft 20 to move axially to change the meshin...

Abstract

The invention provides an oil pump and a vehicle. The oil pump comprises a drive shaft, a driven shaft and a motor, wherein a drive gear fixedly sleeves the drive shaft; a driven gear sleeves the driven shaft; the driven gear is engaged with the drive gear; the motor drives the driven shaft to axially move to change an engaged area of the driven gear and the drive gear. The oil pump can meet needs, under different rotation speeds, of an engine, so that engine oil pressure is kept on relatively stable level; and moreover, the oil pump is simple in structure and is compact in structure, and canreduce processing difficulty of the oil pump.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an oil pump and a vehicle with the oil pump. Background technique [0002] At present, most engines use quantitative oil pumps, and the output flow increases with the increase of engine speed. However, at low speeds, the oil flow rate is low, resulting in insufficient lubrication of the friction surfaces of the engine, causing serious wear of the friction surfaces of the engine, increasing fuel consumption and emissions, and shortening the service life of the engine. At high speed (for example: 5000rpm), according to foreign research data, about 50% of the engine oil with power directly flows back to the oil pump into the oil chamber or oil pan through the pressure relief valve, and the oil pump has done a certain amount of useless work, resulting in Greater energy waste, while accelerating the aging of oil. [0003] In addition, the variable oil pump mostly adopts oil pressur...
