Problems solved by technology

[0004] In order to meet the demand for torque, the existing technology usually chooses to install a deceleration device, or use a motor with a larger torque, or reduce the radius of the driving wheel to solve the problem, but this will increase the product cost or other problems, so there is an urgent need for a A kind of technical scheme that solves the above problems

Abstract

The invention relates to the technical field of electromagnetic clutches, in particular to a planetary electromagnetic clutch. The planetary electromagnetic clutch comprises a mounting seat, and a power shaft, a push piece, a friction piece, a planetary gear transmission assembly and a rest spring arranged on the mounting seat in a penetrating manner. The planetary electromagnetic clutch is provided with an electromagnet and the push piece. The electromagnet generates a suction force if being electrified to attract the push piece to the planetary gear transmission assembly and leans the friction piece to a sun gear, the power shaft rotates and drives the friction piece to rotate, and the friction piece and the sun gear are in contact to rotate synchronously so as to drive the planetary gear transmission assembly to decrease the speed and increase the torque. In case of power failure, the suction force of the electromagnet disappears, and the push piece is far away from the planetary gear transmission assembly under the action of the reset spring, so that the friction piece and the sun gear are separated. The sun gear loses a rotation driving force to achieve a separation and reunion function, and an electromagnetic damping effect can be avoided.

Description

technical field [0001] The invention relates to the technical field of electromagnetic clutches, in particular to a planetary electromagnetic clutch. Background technique [0002] At present, we usually use brushless motors as the power source on small electric vehicles, but when the power supply of the electric vehicle is out of power, if the power is not disconnected, the user will drive the vehicle with manpower and drive the rotor of the motor to rotate at the same time, and the rotor The process of rotation consumes extra energy, and the user also needs to use more force to drive the electric vehicle, and the user experience will be extremely poor due to the existence of electromagnetic damping. In consideration of improving user experience, it is necessary to add a clutch device to the small electric vehicle. Since the torque required by small electric vehicles is generally large, it is a big problem to solve this problem reasonably. [0003] Patent CN203926480U disc...
