Problems solved by technology

At present, China's automobile emission regulations are directly catching up with Europe, and under the environment of increasing energy-saving and environmental protection requirements, large-displacement and high-end vehicles have been equipped with idle start-stop systems since 2015, and will inevitably be introduced to the low-end mass market in the future. Extension, the performance of the existing idling start-stop oil pump is unreliable, it is easy to cause blockage in the oil suction-oil discharge process, the noise is large, and the service life is reduced

Abstract

The invention provides an engine idling start-stop system oil pump. The engine idling start-stop system oil pump comprises a base, a pump body and a rear cover. The pump body is connected with the base and the rear cover. The base is provided with an oil outlet hole and an oil inlet hole. The pump body comprises a shell, a motor, a pump core outer rotor and a pump core inner rotor. The pump core inner rotor is connected to the motor eccentrically. A containing cavity and a plurality of grooves are formed in the pump core outer rotor. The grooves are formed in the periphery of the containing cavity in an annular manner. The pump core inner rotor is provided with a plurality of internal tooth portions. The pump core inner rotor is installed in the containing cavity. The internal tooth portions rotationally get close to or deviate from the grooves correspondingly. Oil suction chambers and oil pumping chambers which change periodically are formed between the internal tooth portions and thegrooves. Therefore, because of eccentric cooperation between the pump core outer rotor and the pump core inner rotor, the engine idling start-stop system oil pump is reliable in performance and higher in market competitiveness.

Description

technical field [0001] The invention relates to the technical field of oil pumps, in particular to an oil pump for an engine idle start-stop system. Background technique [0002] With the rapid development of the automobile industry, various automobile manufacturers continue to develop new energy-saving and environmental protection technologies to improve market competitiveness. Start-stop technology (Start-stop System) is one of them, which is dedicated to minimizing fuel consumption when the engine is idling. When a car is driving in a crowded urban traffic road, it is inevitable to stop and wait for traffic lights, and the energy consumed by the engine at idle speed is meaningless, and the start-stop technology is to avoid the waste of this part of energy, and it is also important for saving energy and reducing emissions. meaning. [0003] The working method of the start-stop system takes automatic transmission vehicles as an example. The driver only needs to apply the ...
