Electromagnetic coil 14 is fixedly installed on body 1, electromagnetic coil 14 is located at the lower section of armature plate 8.
The working principle for the servo-actuated built-in electromagnetic clutch water pump that above embodiment provides is: when sensor detects vapour
The relatively low situation of engine water temperature when vehicle just starts, just sends a signal to automobile ECU, power-off signal is sent to electromagnetism by ECU
Clutch water pump remains powered off electromagnetic coil 14, and armature plate 8 keeps dividing under the elastic force effect of spring leaf 9 with belt pulley 2 at this time
From, i.e., armature plate 8 can't be rotated synchronously with belt pulley 2, and since belt pulley 2 is rotated by driven by engine, so that with movable plate
12 form magnetic vortex with the region below pole ring 10, and under the induced effect of magnetic vortex, pole ring 10 can slowly run, in turn
It drives pump shaft 3 to synchronize to slowly run, guarantees that engine normally heats up.
When sensor detects that engine water temperature is higher, automobile ECU is just sent a signal to, ECU sends power on signal
Electromagnetic clutch water pump is given, electromagnetic coil 14 is made to be powered, electromagnetic coil 14 generates magnetic force at this time, so that armature plate 8 is by magnetic
Gravitational attraction and overcome the active force of spring leaf 9 to be then moved downward to and couple with belt pulley 2 so that armature plate 8 and belt
Wheel 2 rotates synchronously, and since pole ring 10, spring leaf 9, armature plate 8 are installed together, pole ring 10 and spring leaf 9 are also same
Step rotation, and then pump shaft 3 is driven to rotate synchronously, so that pump shaft 3 can guarantee hair with belt pulley 2 with 1:1 revolving speed high-speed rotation
Motivation obtains timely cooling down.
By the way that permanent magnet 11 to be mounted on to the bottom surface of pole ring 10, it is made to deviate from end cap face of electromagnetic clutch water pump, thus
The impurity such as flying dust or the soil under external environment can be largely reduced to permanent magnet by the protective effect of pole ring 10
11 influence, so that the electromagnetic clutch water pump can adapt to work in the presence of a harsh environment, by being arranged in the lower section of permanent magnet 11
It with movable plate 12, is rotated synchronously with movable plate 12 and belt pulley 2, so that can normally generate magnetic vortex, Jin Erbao below pole ring 10
Card pump shaft 3 in the case where electromagnetic coil 14 powers off, which also can be vortexed to drive by magnetic, to slowly run, i.e., can maintain completely
Normal, the guarantee electromagnetic clutch pump working stabilization of magnetic field force size.
Preferably, fixed block 5 is the cheese block that middle part offers through-hole, and pump shaft 3 and through-hole are interference fitted,
In, the outer of 5 top end face of fixed block is equipped with step spring leaf 9 and pole ring 10 is stuck in step top surface and by the more of annular setting
A fastening bolt 15 is connected on fixed block 5, this is compact-sized, firmly installs, and for later period dismounting maintenance also compared with
For convenience.
More preferably, armature plate 8 is connected on the bottom surface of spring leaf 9, and armature plate 8 is in a ring and positioned at close to spring
The position of 9 outer of piece, the elastic force being subject in this way be it is most sufficient, i.e. armature plate 8 can be not powered in electromagnetic coil 14 and do not had
Have and keeps that armature plate 8 and belt pulley 3 is made to keep good discrete state in the case where being attracted by magnetic force.
In addition, in the present embodiment, can make to be interference fitted with movable plate 12 and belt pulley 2, it in this way can be secured with movable plate 12
It is connected on belt pulley 2 and no setting is required extra screw connection structure, to guarantee that the installation of pole ring 10 will not be caused
Interference.
Above-described embodiment is the preferable implementation of the present invention, and in addition to this, the present invention can be realized with other way,
Do not depart from the technical program design under the premise of it is any obviously replace it is within the scope of the present invention.
