Electric piston driven type electromobile suitable for electric braking

Abstract

The invention relates to an electric piston driven type electromobile of which the electric piston electromotor replace a diesel engine in an original motor vehicle. The electric piston driven type electromobile is suitable for electric braking and comprises an electric piston electromotor, a clutch, a gearbox, an electromobile transmission system and a starting system. When the electromobile operates, the current direction of a coil of an electromagnet in the electric piston electromotor always keeps constant; and when a piston is about to reach an upper stop point and a lower stop point, the electromagnet is controlled to rotate to 180 DEG around a height center line of the electromagnet so as to rapidly switch the magnetic polarities of the upper end and the lower end of the electromagnet so that the electromagnet repeatedly generates acting forces on the piston to drive the crankshaft and accordingly the flywheels outputs positive or negative torque outwards, therefore, the time delay in the prior art, caused by the failure of instantaneous reversal of the coil current, is avoided, and the travelling stability of the electromobile of the invention is ensured.

Description

technical field [0001] 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 electric braking. Background technique [0002] 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 vehicles such as automobiles and motorcycles.

AI Technical Summary

Problems solved by technology

[0004] 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

[0007] 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.
