Problems solved by technology

In the process of temporary parking of traditional cars, the engine is still running, and the energy is still being consumed, but the consumed energy does not make useful work, and the exhaust gas exhausted increases the exhaust emissions of the car. This working method is consistent with energy saving and emission reduction. New requirements contradict

Abstract

The invention belongs to automobile parts, and particularly relates to an electric liquid pump for an automobile starting and stopping system. A controller (2) is fixed to a controller bracket (4) through screws, a motor stator (10) is fixed in the upper end of a shell (11), a motor rotor (7) is fixed to the upper end of a hollow shaft (8), an insulating sleeve (5) is fixed to the shell (11) through screws, the hollow shaft (8) penetrates into a first sliding bearing (3) and a second sliding bearing (12), magnetic steel (18) is fixedly installed at the upper end of the hollow shaft (8), a side plate (13), an oil pump stator (15) and a pressure plate (16) are fixed to an oil pump cover (17) in a limiting and penetrating mode through locating pins and are arranged inside a cavity of the shell (11), and an oil pump rotor (14) is connected to the lower end of the hollow shaft (8) through splines. The electric liquid pump for the automobile starting and stopping system is compact in structure, low in energy consumption and low in noise.

Description

technical field [0001] The invention belongs to auto parts, in particular to an electro-hydraulic pump for an auto start-stop system. Background technique [0002] With the worldwide requirement of energy conservation and emission reduction, all walks of life and fields have stepped up the pace of energy conservation and emission reduction. As the main consumer of contemporary energy and the main producer of exhaust gas, automobiles are the first among them. Therefore, Various new technologies are constantly being developed and used in the automotive industry, and the start-stop technology is a new technology for energy saving and emission reduction in the contemporary automotive industry. During the temporary parking of a traditional car, the engine is still running, and the energy is still being consumed, but the consumed energy does not make useful work, and the exhaust gas exhausted increases the exhaust emission of the car. Contrary to the new requirements. Contents ...
