Description

[0001] This application is a divisional application, the application number of the original application is 201110027288.8, the application date is: January 25, 2011, and the name of the invention is: electric piston-driven electric vehicle suitable for downhill braking. technical field [0002] The invention relates to the technical field of electric vehicles driven by electric piston motors, in particular to an electric piston-driven electric vehicle suitable for downhill braking. 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. ...

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.
