Abstract

The invention discloses a vehicle engine starting system. The vehicle engine starting system comprises a motor, a water pump, a first clutch and a second clutch, wherein the water pump is used for cooling an engine. The motor comprises an output shaft, wherein one end of the output shaft is connected with the water pump through the first clutch, and the other end of the output shaft is connected with a flywheel of the engine through the second clutch. The first clutch is an electromagnetic clutch and comprises a driving piece and a driven piece, wherein the driving piece is in drive connection with the output shaft of the motor and can rotate along with the output shaft, the driven piece is in drive connection with the water pump so that the water pump can rotate along with the driven piece, the driving piece and the driven piece are respectively provided with teeth, the teeth of the driving piece can be meshed with the teeth of the driven piece, the driving piece can move between the first position and the second position, the driving piece is meshed with the driven piece when located in the first position so that the water pump can be driven to work, the driving piece is not meshed with the driven piece when located in the second position, the driving piece moves from the first position to the second position when the first clutch is powered on, and then the motor starts the engine.

Description

technical field [0001] The invention relates to a vehicle engine starting system. Background technique [0002] With the deterioration of the global environment, environmental issues have become a survival issue that people must face, and energy conservation and emission reduction have become an important consideration for most industries. In order to comply with the development trend of energy saving and emission reduction, automobile manufacturers have vigorously developed and promoted the start-stop system. The start-stop system is temporarily closed under the parking and waiting state (such as parking before a red light or when encountering a traffic jam). engine, so as to save fuel and reduce exhaust emissions, and restart the engine when changing to the driving state. [0003] In the existing vehicle engine start-stop system, each motor has a single function, such as the starter motor does not work after starting the engine, the motor utilization rate is low, and the ...
