Abstract
The permanent magnetic pole block and friction piece are installed on the driving rotor and the induction piece and clutch piece are installed on the driven rotor, the driving rotor and the driven rotor can slip relatively along the the same axial direction, the permanent magnetic pole block and induction piece as well as the friction piece and the clutch piece are separately and correspondingly installed along the radial direction of the rotor, on the driven rotor, the axial moving device and axial holddown device are also installed. For said clutch, the joint of the driving rotor and the driven rotor is implemented while their relative rotation speeds are quite lose, thus the joint is mooth, the drive efficiency is high and the loss of friction piece is small.
Description
The present invention relates to a kind of clutch, particularly a kind of permanent-magnet clutch for automobile.
At present, on the motor vehicle such as various types of automobiles, tractor, the clutch of adapted mostly is friction plate clutch.Shortcomings such as this clutch exists in practicality that the friction plate abrasion is fast, combination force is poor, easily skids, transmission of power is not steady, and transmission efficiency is low.
The objective of the invention is to, overcome the deficiency of friction plate clutch, a kind of transmission efficiency height is provided, reliable transmission, steadily durable, the novel permanent magnetic automobile clutch that permanent magnetism transmission simple in structure combines with friction driving.
The object of the present invention is achieved like this: permanent-magnet pole piece and friction plate are installed on power rotor, induction piece and clutch-plate are installed on the driven rotor, power rotor and driven rotor along the same axis can relative slippages, permanent-magnet pole piece and induction piece, friction plate and clutch-plate also are equipped with axial moving device and axial pressing device respectively along the corresponding installation of rotor radial on the driven rotor.When separated state, gapped between driving and driven rotor, power does not transmit.When needs in conjunction with the time, driven rotor is to power rotor one side slip, gradually near power rotor, this moment, the magnetic field of permanent-magnet pole piece produced running torque on induction piece, drove the driven rotor rotation.Along with the gap between driving and driven rotor continues to reduce, magnetic induction moment increases gradually, and the driven rotor rotating speed increases gradually, speed discrepancy between driving and driven rotor is corresponding to be reduced, when the driven rotor rotating speed reached certain value, friction plate just combined with clutch-plate, produced friction torque.Under magnetic induction moment and friction torque double action, make the increase of driven rotor rotating speed reach the synchronous speed of power rotor, realize the bonding state of clutch.This clutch also can be made the one chip of driving and driven rotor one single combination or the multidisc structure of many rotors combination according to different needs.
The friction plate of this permanent-magnet clutch for automobile provided by the invention, be to produce certain induced moment at power rotor, ordering about driven rotor reaches under the condition of certain rotating speed to finish with driven rotor and combines, so the friction plate and the relative rotation speed between the clutch-plate on the driven rotor of power rotor are more approaching, impel contact friction to reduce significantly, friction temperature is unlikely overheated, thereby has reduced the abrasion degree greatly.So it is in conjunction with steadily reliable, noise is low, the life-span is long, driving torque is big, the transmission efficiency height.Simple in structure, volume is little, in light weight, comprehensive superiority is outstanding relatively.Can use at various types of motor vehicle and needing on the gearing of clutch.
Below, be described further in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of permanent-magnet clutch for automobile.
In Fig. 1, permanent-magnet pole piece 2 and friction plate 3 are installed on the power rotor 1, clutch-plate 4 and induction piece 5 are installed on the driven rotor 6.Power rotor can relative vertically slippage with driven rotor.Permanent-magnet pole piece 2 and induction piece 5, friction plate 3 and clutch-plate 4 radially corresponding installations respectively.Friction plate 3 is along the thickness of rotor axial thickness greater than permanent-magnet pole piece 2, and to guarantee clutch under bonding state, permanent-magnet pole piece 2 does not contact mutually with induction piece 5, and only friction plate 3 contacts with clutch-plate 4.Axial moving device 7 and axial pressing device 8 are housed on driven rotor 6.
