Embodiment Construction

[0024] The technical solutions and other beneficial effects of the present invention will be made obvious by describing the specific embodiments of the present invention in detail below in conjunction with the accompanying drawings.

[0025] figure 1 Shown is a simplified schematic diagram of the vehicle engine starting system of the present invention.

[0026] Figure 2 to Figure 5 A vehicle engine starting system according to an embodiment of the present invention is shown.

[0027] See figure 1 versus figure 2 , A vehicle engine starting system, including a motor 10 and a water pump 30 for cooling the engine 20, wherein the motor 10 includes an output shaft 12, and both ends of the output shaft 12 pass through first and second clutches respectively 40 and 50 are connected to the water pump 30 and the flywheel 22 of the engine 20. The motor output shaft 12 can selectively rotate in one of the two opposite directions to selectively start the engine 20 or drive the water pump 30.

Abstract

The invention discloses a vehicle engine starting system, which comprises a motor and a water pump for cooling the engine, wherein the motor comprises an output shaft; one end of the output shaft is connected with the water pump through a first clutch, and the other end of the output shaft is connected with a flywheel of the engine through a second clutch; and the output shaft of the motor can optionally rotate in one of two opposite directions so as to optionally start the engine or drive the water pump. According to the starting system, the motor is started after the engine is started, and serves as a driving motor for the water pump, and a motor can be eliminated, so that power can be saved, the cost can be reduced, and a vehicle cooling system is optimally controlled.

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 survival issues that people must face, and energy conservation and emission reduction have become important considerations 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, which is temporarily closed in the state of parking waiting (such as stopping at a red light or stopping in traffic jam) The engine saves fuel and reduces exhaust emissions, and restarts the engine when shifting to a running state. [0003] In the existing vehicle engine start-stop system, each motor has a single function. For example, the starter motor stops working after starting the engine, the motor utilization is low, and the cost is high. [0004] The invention aims to pro...
