This utility model compared with the existing technology, has an advantage in that this utility model will not produce axle when clutch works
To impulsive force, and abrasion to rubbing surface has compensating action when clutch works long hours, and this relies primarily on and leads on friction plate
To the design of groove so that the pressure between friction plate and electromagnetic clutch shell increases, friction along with the increase of transmission moment of torsion
Sheet can turn tighter and tighter with clutch outer member.When clutch outer member rotates, friction plate promotes under the elastic force effect of compression spring
The equidirectional rotation of friction plate, meanwhile, the second alignment pin relative motion in gathering sill being fixed on body, gathering sill and friction
Wedge like structure is constituted so that the pressure between limit friction sheet and clutch outer member is along with transmission moment of torsion between face
Increase and increase.That is, when clutch outer member rotates, friction plate can turn tighter and tighter with clutch outer member.Even if spring failure is also
Can ensure that the moment of torsion that transmission is sufficiently large, it is ensured that water pump normally works.

[detailed description of the invention]
The utility model is described in further detail below in conjunction with the accompanying drawings, the structure of this device and the principle people to this specialty
For be the most clearly.Should be appreciated that specific embodiment described herein, and need not only in order to explain this utility model
In limiting this utility model.
This utility model relates to a kind of Novel electromagnetic clutch structure that may be mounted on vehicle water pump, particularly relates to one
Control what friction plate radially contacted with electromagnetic clutch shell or separates by the effect of electromagnetic core power on/off and compression spring
Electromagnetic clutch.
As it is shown in figure 1, shown in switch water pump electromagnetic clutch assembly exploded view, mainly include, water pump cover 1, electromagnetism
Iron core 2, press-fit axle sleeve 3, diaphragm spring the 4, first alignment pin 5, compression spring 6, friction plate 7, clutch body 8, second position
Pin 9, water pump drive spindle 10, rolling bearing 11, clutch outer member 12, water pump pulley 13, water pump pulley are fixed bolt 14, are prevented
Dirt lid 15.
Friction plate 7 can slide axially on clutch body 8, after friction plate 7 compresses compression spring 6, by being connected in
Two the second alignment pins 9 on clutch body 8 are spacing.First alignment pin 5 is connected on diaphragm spring 4, and the first location
Pin 5 ledge inserts in the spacing hole 7-1 on friction plate 7.Each friction plate 7 be provided with two gathering sill 7-2 and one spacing
Hole 7-1, the second alignment pin 9 slides in gathering sill 7-2 so that friction plate 7 is fitted with clutch body 8 or separates, electromagnetism
Certain gap is there is between iron core 2 and diaphragm spring 4.As in figure 2 it is shown, when direction rotates clutch outer member 12 as shown,
Friction plate 7 promotes the equidirectional rotation of friction plate 7 under the elastic force effect of compression spring 6, meanwhile, is fixed on the location on body 8
Pin 9 is relative motion in gathering sill 7-2, constitutes wedge like structure so that between 7 and 12 between gathering sill and rubbing surface
Pressure increase along with the transmission increase of moment of torsion.It is to say, when clutch outer member 12 rotates as shown, friction plate with from
Clutch shell can turn tighter and tighter.Even if spring 6 lost efficacy it is also ensured that transmit sufficiently large moment of torsion, it is ensured that water pump normally works.
Electromagnetic clutch of the present utility model is arranged on vehicle water pump, it is possible to achieve when engine cold starts, water
Pump quits work, and shortens engine warm-up time, improves burning and the discharge of electromotor, reduce oil consumption simultaneously.Groundwork is former
Reason is, when electromagnetic clutch is energized, and electromagnetic core 2 adhesive diaphragm spring 4 so that electromagnetic core 2 can not phase with diaphragm spring
To motion, the first alignment pin 5 being now connected on diaphragm spring 4 stops friction plate 7 by the spacing hole 7-1 on friction plate 7
Rotate together with clutch outer member 12, the second alignment pin 9 two ends being connected on clutch body 8 guiding on friction plate 7
Slide in groove 7-2, compress compression spring 6 so that separated with clutch outer member 12 by friction plate 7, the most only water pump pulley
13 rotate together with clutch outer member 12, water air pump inoperative, and water pump pulley 13 drives rolling bearing 11 to dally.Work as electromotor
Water temperature reaches limiting design value, when needing pump working, and electromagnetic clutch power-off, electromagnetic core 2 separates with diaphragm spring 4, now,
Under the elastic force effect of compression spring 6, friction plate 7 circumference on clutch body 8 is slided so that the second alignment pin 9 is in friction
Relatively slide in gathering sill 7-2 on sheet 7 so that the radially laminating of friction plate 7 and clutch outer member 12, produce radial friction transmission
Moment of torsion, water pump is started working.
