Description
Technical field
The present invention relates to a kind of clutch, relate in particular to a kind of magnetic clutch.
Background technique
Clutch is installed between motor and the speed changer, is the total member that directly interrelates with motor in the automotive transmission, is the parts of cut-out and transferring power between motor and the automotive transmission.To the whole process of normally travelling, the driver is controlled clutch as required from starting for automobile, motor temporarily is separated with power train or engages gradually, with the power that cuts off or the transmission motor is exported to power train.Now widely used clutch is friction clutcch, mainly relies on friction between the driving and driven part to come transferring power and can separate.Just operation, existing automobile clutch mostly is foot-operated mechanical clutch, complex structure, and reaction velocity is slow, Reliability of Microprocessor is low.Magnetic clutch has appearred in the development along with technology, and traditional manipulation form is also to automated form development.Magnetic clutch leans on the power on/off of coil to come the Engage and disengage of solenoidoperated cluthes, produces magnetic force adhesive armature slice during coil electricity, and clutch is in jointing state; Armature rebounds during coil blackout, and clutch is in separated state.Magnetic clutch has improved the reaction velocity of clutch greatly.Because clutch is similar to switch, play joint or the effect of dialysis transmission of power, therefore, any type of automobile has engaging and disengaging gear, just the form difference.
The new energy car is the novel automobile of automobile industry reply energy scarcity, refers to all other energy automobiles except gasoline, diesel engine, such as fuel cell car.The actuation techniques of new energy vehicle and traditional combustion engine automobile have no small difference, and wherein a class actuation techniques has very large development prospect, is exactly the wheel hub motor technology.Wheel hub motor is called again the wheel inner electric machine, the characteristics of its maximum all are incorporated into power, rotation and braking device in the wheel hub exactly, therefore the mechanical part of electric vehicle are simplified greatly, and have been improved motor drive efficiency, alleviate the car load deadweight, reduced its transmission and added losses.Existing wheel hub motor generally only has a rotor, wheel hub motor is less to the driving force of wheel hub, in order to improve wheel hub motor to the driving force of wheel hub, claimant's application number is 201210285107.6 denominations of invention just provides the large double wheel hub of a kind of like this driving force or many wheel hub motors for the patent of invention of " a kind of double rotor or many rotor hubs motor ".
Be illustrated in figure 1 as a kind of specific embodiment of above-mentioned double rotor wheel hub motor, in this double rotor wheel hub motor embodiment, rotor 20 ＇ and stator 22 ＇ are set in motor shaft 10 ＇, stator 22 ＇ are located in the hollow inner casing of rotor 20 ＇, be provided with clutch 30 ＇ between two rotor 20 ＇, during use, can as required two rotors be joined together common driving electric vehicle hub rotates, also can be as required with clutch 30 ＇ dialysis, thereby two rotor 20 ＇ separately, only uses one of them rotor drive hub to rotate.The clutch that is used for this technological scheme must be that end cap can rotate together along with rotor 20 ＇.
Yet, existing magnetic clutch, initiatively end cap is as stator, can't rotate, and drive end covers and has through hole, pass through from this through hole with the electric wire of drawing of electromagnetic coil energising, this more so that initiatively end cap can only fix and can not rotate, this just applies for embodiment in " a kind of double rotor or many rotor hubs motor " patent of invention so that existing clutch can't be applied to the claimant.In addition, existing magnetic clutch with axle as rotor, by at axle projection being set, in the recessing of driving disc relevant position, groove perhaps all is set on axle and driving disc, come driving torque by key, rotate thereby drive driving disc by axle, like this, the transmission of torque just depends on projection or the key on the axle, torque transfer capability is poor, and driving disc is the parts an of necessity, can not cancel.
The model utility content
For overcoming the defective of above-mentioned prior art, technical problem to be solved in the utility model is, thereby provide a kind of common drive hub that a plurality of rotors of many rotor hubs motor can be bonded together to rotate, and transmitting torque electromagnet clutch large, simple in structure.
In order to solve the problems of the technologies described above, the embodiment of the invention provides a kind of magnetic clutch, and it comprises driving part, driven member and arbor, and described driving part and driven member relatively are set in arbor; Described driving part comprises initiatively end cap and electromagnetic coil, and it is inner that described electromagnetic coil is fixed in described active end cap, and described active end cap also is provided with friction plate facing to described driven member one end; Described driven member comprises driven end cap and armature, and described armature is dismountable to be installed on described driven end cap and to be positioned at the relative end with described active end cap of described driven end cap; Being provided with between described electromagnetic coil and the described arbor can be to the conductive hoop of electromagnetic coil conduction, described conductive hoop and described electromagnetic coil drive fit; But described arbor inside is provided with the wire guide of laying wire, and described wire guide is provided with the port that communicates with conductive hoop, and the port is provided with the conducting plate that contacts with described conductive hoop.
