Electric power piston driving type electric vehicle and working method thereof

Abstract

The invention relates to an electric power piston driving type electric vehicle which utilizes an electric power piston motor to replace gasoline and diesel engines in the previous motor vehicle and is suitable for electric power braking, and a working method thereof. The electric vehicle comprises an electric power piston motor, a clutch, a speed changing box, a vehicle transmission system and a starting system. When the electric power piston driving type electric vehicle works, a coil current direction of an electromagnet in the electric power piston motor keeps unchanged all the time; when a piston is about to reach upper and lower stopping points, the electromagnet is controlled to rapidly rotate along a height central line by 180 degrees so as to rapidly switch magnetic polarities of upper and lower ends of the electromagnet; therefore, the electromagnet repeatedly generates an acting force on the piston to drive a crank shaft and a fly wheel outwards outputs a positive or negative torque; and the electric power piston driving type electric vehicle avoids the delaying in the prior art that coil current cannot realize instantaneous reversing and ensures the driving stability of the electric vehicle.

Background technique [0003] Chinese patent document CN101860168A discloses an electric motor, which removes the traditional engine air supply, fuel supply, exhaust, and ignition systems, and replaces them with electromagnet components. The piston is embedded with a permanent magnet, and then the current direction of the electromagnet coil is controlled. The piston is controlled to move up and down in the cylinder, and the piston outputs power through the connecting rod and crankshaft mechanism. The electric motor is suitable for vehi...

AI Technical Summary

Problems solved by technology

[0005] The disadvantage of the above-mentioned electric piston motor in the prior art is that the magnetic polarity of the electromagnet is changed by frequently switching the direction of current flowing through the electromagnet coil, thereby controlling the direction of the force between the electromagnet and the piston, and then controlling the direction of the piston. However, in the actual implementation process, since the current direction of the electromagnet coil cannot be changed instantaneously, the continuity and stability of the output power or torque of the motor cannot be guaranteed

[0008] In addition, the existing electric vehicles often use motors to directly drive the wheels. Retrofitting existing gasoline and diesel vehicles into electric vehicles directly driven by motors is costly, cumbersome and difficult to implement.
