The electromagnetic block type permanent magnet synchronous motor comprises a support frame, a stator fixed on the support frame, an electromagnetic block fixed on the stator, a front rotor and a rear rotor, wherein a certain air gap is kept between the front rotor and the rear rotor, the connecting shaft, the output flange and the input flange are connected in a middle hole of the support frame through bearings, the front rotor and the rear rotor are respectively connected to two sides of the connecting shaft in the axial direction, and the output flange and the input flange are respectively arranged on the outer sides of the front rotor and the. The utility model discloses a put the motorcycle type that eddy current retarder mainly was applicable to with leading engine mounting form in, the utility model discloses the coil that the structure used is the twice of the coil quantity that ordinary birotor eddy current retarder used, and consequently the produced moment of eddy current retarder of this structure is great, makes eddy current retarder become probably to bigger moment development.
Description
Technical field
The utility model relates to the automobile retarder technical field, relates in particular to a kind of current vortex retarder that is installed on the drive path of automobile gearbox rear portion.
Background technology
Automobile retarder is the many a kind of automobile brake auxiliary devices of domestic in recent years use, and at present mainly based on current vortex retarder, other forms of retarder has Retarder, permanent-magnet speed buffer, generator-type retarder, exhaust brake retarder etc.The operation principle of current vortex retarder all is that the rotor cutting magnetic line produces current vortex, forms braking moment.Domestic existing current vortex retarder can only adaptively be installed on the automobile gearbox equipped at outlet port substantially.Do not possess the gearbox of mounting condition for some, be difficult to realize the installation of retarder.
The utility model content
The utility model is at above problem, and a kind of gearbox rear portion in the truck powered rotation system of being installed in is provided, and can be connected the mid-current vortex retarder on the power transmission shaft.
The technical solution of the utility model is: comprise bracing frame, be fixed on stator on the bracing frame, be fixed on the electromagnetic block on the stator and keep the forward and backward rotor of certain air gap with the electromagnetic block yoke plate, it also comprises connecting axle, output flange, input flange, connecting axle is connected in the mesopore of bracing frame by bearing, forward and backward rotor is connected to the axial both sides of connecting axle, at the connecting axle two ends, the forward and backward rotor axial outside is respectively equipped with output flange, input flange.
Be provided with the jockey that connects the vehicle longeron in the circumferential outside of bracing frame.
Mid-current vortex retarder of the present utility model mainly is applicable to the vehicle (based on truck) with the front-mounted engine installation form.Operation principle of the present utility model is identical with the common electrical eddy current retarder, and uniqueness is in rotor part and stator component and links together by power transmission shaft, bearing.Be specially adapted on automobile gearbox or back axle, can't installing the occasion of common electrical eddy current retarder.The coil that structure of the present utility model is used is the twice of the coil quantity used of common birotor current vortex retarder, so the moment that current vortex retarder produced of this structure is bigger, makes current vortex retarder develop into possibility to bigger moment.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is unshakable in one's determination among the figure, the 2nd, and yoke plate, the 3rd, coil, the 4th, bracing frame, the 5th, sealing ring, adjustment circle, the 6th, output flange, the 7th, connecting axle, the 8th, bearing, the 9th, back rotor, the 10th, air gap, the 11st, input flange, the 12nd, preceding rotor.
Embodiment
As Fig. 1,2, the utility model comprises bracing frame 4, be fixed on stator on the bracing frame 4, be fixed on the electromagnetic block on the stator and keep preceding rotor 12, the back rotor 9 of certain air gap 10 with electromagnetic block yoke plate 2, it also comprises connecting axle 7, output flange 6, input flange 11, connecting axle 7 is connected in the mesopore of bracing frame 4 by bearing 8, before rotor 12, back rotor 9 be connected to the axial both sides of connecting axle 7, at connecting axle 7 two ends, preceding rotor 12, back rotor 9 axially are respectively equipped with output flange 6, input flange 11 in the outside.
Be provided with the jockey that connects the vehicle longeron in bracing frame 4 circumferential outsides.
Electromagnetic block of the present utility model is made up of iron core 1, yoke plate 2, coil 3, and unshakable in one's determination 1 is fixedly connected on the bracing frame 4, forms stator of the present utility model.Bracing frame 4 is installed on the automobile longitudinal girder.
Be provided with sealing ring in preceding rotor 12, back rotor 9 and output flange 6, input flange 11 and connecting axle 7 jockeys, adjust circle 5, play the effect of air gap 10 between adjustment back rotor 9, preceding rotor 12 and the yoke plate 2.Output flange 6, input flange 11 link to each other with the automobile universal drive shaft.
During installation, the propeller shaft length of automobile must be shortened.During non operating state, rotor part plays the effect of transmitting the car engine mechanomotive force.The electric current of closing coil 3 during work, the magnetic field of formation alter polarity is at preceding rotor 12 and the back rotor 9 inner current vortexs that form, generation plugging moment, automobile brake.The size of current of working quantity by regulating winding 3 or regulating winding 3 work realizes the control to retarder moment.
Claims (2)
1, a kind of mid-current vortex retarder, comprise bracing frame, be fixed on stator on the bracing frame, be fixed on the electromagnetic block on the stator and keep the forward and backward rotor of certain air gap with the electromagnetic block yoke plate, it is characterized in that, it also comprises connecting axle, output flange, input flange, connecting axle is connected in the mesopore of bracing frame by bearing, forward and backward rotor is connected to the axial both sides of connecting axle, and at the connecting axle two ends, the forward and backward rotor axial outside is respectively equipped with output flange, input flange.
2, a kind of mid-current vortex retarder according to claim 1 is characterized in that, is provided with the jockey that connects the vehicle longeron in the circumferential outside of bracing frame.
