Abstract

The invention belongs to the technical field of automobile engineering and discloses an oil pump. The oil pump comprises an oil pump body, a liquid level sensor and a cavity. The bottom of the cavity communicates with an oil cavity of the oil pump body through an oil passing hole. The liquid level sensor is arranged in the cavity. The oil pump provided by the invention can accurately measure the oil amount and has good anti-oscillation capability.

Description

technical field [0001] The invention relates to the technical field of automobile engineering, in particular to an oil pump. Background technique [0002] At present, the remaining oil quantity of the car is mainly measured by the oil quantity sensor. The principle is that the oil float drives a wire-wound sliding resistor, and the oil level changes the resistance value of the sliding resistor, so that the oil quantity can be measured. [0003] The oil quantity sensor is widely used and has a simple structure. However, when the car is running bumpy or goes uphill or downhill for a long time, the oil level will fluctuate or be seriously inclined. Therefore, the collected resistance There will be a large deviation between the signal and the actual resistance value, and the oil volume data after the resistance conversion will have a large error, resulting in poor calculation accuracy of the cruising range and less guiding significance for the driver.
