Description
Technical field
The utility model is related to a kind of electromagnetic clutch water pumps with double frictional disks.
Background technology
Electromagnetic clutch water pump is the important accessory of automobile engine, and effect is to provide the cold of quantitative level pressure to engine
But liquid.This kind of electromagnetic clutch water pump can determine its leaf according to the height of the engine water temperature detected in practical work process
Wheel is full-speed operation or half-speed operation, has energy-efficient effect.
The composition component of above-mentioned electromagnetic clutch water pump generally includes main shaft, the pump housing, impeller, belt pulley suction in the prior art
Disk, electromagnetic coil assembly, metal friction disk, magnetic conduction drive ring, permanent magnet and permanent magnet retainer plate；Impeller is fixed on main shaft one
End, and main shaft then passes through the pump housing to be arranged.Belt pulley sucker is a kind of integrated component that sucker is combined with belt pulley, is entire water
The driving link in structure system is pumped, is set on main shaft by bearing, when actual operation, belt pulley sucker synchronous is charged by interior
Machine is driven by belt to be rotated.Electromagnetic coil assembly be mounted on belt pulley suction cup interior, can be adsorbed after energization by flange with
The fixed metal friction disk of main shaft, so that belt pulley sucker can drive main shaft and its impeller high speed rotation together.Permanent magnetism

Enough speed stabilizing lag rotations.But disadvantage is also evident from, and the presence of magnetic conductive groove reduces between metal friction disk and belt pulley sucker
CONTACT WITH FRICTION area, reduce frictional force so that electromagnetic coil assembly obtain it is electric in the case of, metal friction disk and belt pulley are inhaled
The transmission stability of friction torque and reliability substantially reduce between disk.This is quite contradictory place in conventional design, is both needed
Designed magnetic conductive groove enhancing eddy current effects are wanted, but wish to eliminate surface magnetic conductive groove when metal friction disk adsorbs simultaneously again,
Enhance its contact area, and then reinforces suction and torque transmission.
2）Known electromagnetic clutch water pump mechanism often obtains electric, metal friction disk suction in electromagnetic coil assembly
Attached belt pulley sucker transmits torque, and since electromagnetic coil assembly is different from permanent magnet, adsorption capacity relies on current control, exists not
Stability.In addition the unreliability that known metal frictional disk torque recited above transmits, leads to existing electromagnetic clutch water
The global reliability and stability of pump work are all relatively low.
3）Since it is known electromagnetic clutch water pump work when be switched at full speed, once there is electric fault in automotive interior,
Water pump can only be with half-speed operation, and after such engine water temperature rapid increase, driver tends not to find, under such situation, hair
Motivation is easy to scaling loss, and there are safety issues.
Therefore urgently there is new scheme in the prior art to replace above-mentioned known electromagnetic clutch water pump power to transmit knot
Structure is accomplished to enhance stability and reliability that torque transmits, and then ensures the stability and reliability of entire pump working.
