Embodiment 1

[0036] Please refer to figure 2 , image 3 , the first embodiment provides a maglev clutch system 100, including a controller 101, a motor 102 and a worm 103, a maglev track 104 for suspending the motor 102, and one of the housing of the motor 102 and the worm 103 is set There is an electromagnet 105, and the remaining one is set to be made of magnetically conductive material. The controller 101 circuit is connected with the electromagnet 105 and the motor 102, and is used to control the change of the magnetic field of the electromagnet 105 so that the motor 102 moves closer or farther along the maglev track 104. The direction of the worm 103 is moved in suspension, so that the motor 102 and the worm 103 are in a combined state or in a separated state.

[0037] Please refer to figure 2 The electromagnet 105 may be disposed at one end of the housing of the motor 102, specifically, may surround a circumferential surface fixedly disposed on the housing of the motor 102 or par...

Embodiment 2

[0041] The second embodiment provides a maglev clutch system 100 . Please refer to Figure 4 , the second embodiment is improved on the basis of the first embodiment, the difference is that the housing of the motor 102 and the worm 103 are provided with electromagnets 105, to replace one of the housing of the motor 102 and the worm 103 as a guide A solution made of magnetic materials.

[0042] The control method of the maglev clutch system of the second embodiment is as follows: when the controller 101 feeds a current to the electromagnet 105, the two electromagnets 105 feed the current to generate a magnetic field; , the direction of the magnetic field generated by the two electromagnets 105 is opposite, the motor 102 and the worm 103 attract each other, and the motor 102 moves along the magnetic levitation track 104 to the direction close to the worm 103, so that the motor 102 and the worm 103 are in a combined state When the direction of the two electromagnets 105 connect...

Embodiment 3

[0045] The third embodiment provides a maglev clutch system 100 . Please refer to Figure 5 , the third embodiment is improved on the basis of the first or second embodiment, the difference is that the maglev clutch system 100 also includes an electromagnetic control module 106, the controller 101 is connected to the electromagnet 105 through the electromagnetic control module 106, The controller 101 controls the change of the magnetic field of the electromagnet 105 through the electromagnetic control module 106 to levitate the motor 102 along the magnetic levitation track 104 toward or away from the worm 103 , so that the motor 102 and the worm 103 are in a combined or separated state. That is, the electromagnetic control module 106 is used to replace the controller 101 to control the on or off of the electric current of the electromagnet 105 , and to control the direction of the electric current of the electromagnet 105 to control the direction of the magnetic field of the e...

Abstract

The invention provides a vehicle, a magnetic levitation clutch system, an electric power steering system and a control method. The magnetic levitation clutch system comprises a controller, a motor, aworm and a magnetic levitation track; an electromagnet is arranged on one of a shell of the motor and the worm; and an electromagnet is arranged on the other one of the shell of the motor and the wormor the other one of the shell of the motor and the worm is made of a permeability magnetic material. The electric power steering system and the control method thereof comprise the magnetic levitationclutch system; according to a steering signal or a combined strategy of a steering signal and a vehicle speed signal, the motor is controlled to be suspended by using a magnetic field of the magneticlevitation track, and the motor can rapidly move relative to the magnetic levitation track by using the magnetic field change of the electromagnet so that the motor and the worm of the magnetic levitation clutch system are combined or separated; and whether the motor is started to operate or not and whether a steering power is provided to the vehicle or not are controlled. The vehicle, the magnetic levitation clutch system, the electric power steering system and the control method have the advantages of fast response, small resistance and small noise.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle, a magnetic suspension clutch system, an electric power steering system and a control method. Background technique [0002] The electric power steering system is widely used because of its compact structure, energy saving and emission reduction, and rich tuning functions. The full English name of the electric power steering system is Electronic Power Steering, referred to as EPS, which uses the power generated by the electric motor to assist the driver in power steering. EPS is generally composed of a torque sensor, an electronic control unit, a motor, a reducer, a mechanical steering gear, and a battery power supply. Among them, the torque sensor is also referred to as a steering sensor or a torque sensor. Its main working principle is that when the car is turning, the torque sensor will detect the torque of the steering wheel and the direction of the intende...
