Description
Technical field
The present invention relates 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, is played an important role of energy saving.
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 is then set through the pump housing.Belt pulley sucker is the integrated component that a kind of sucker is combined with belt pulley, is entire water
The driving link in structure system is pumped, is set in by bearing on main shaft, during actual operation, belt pulley sucker is charged by interior synchronization
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 to rotate at a high speed together.Permanent magnetism
Body is fixed on the inner wall of permanent magnet retainer plate, and permanent magnet retainer plate is then fixed with belt pulley sucker, and magnetic conduction drive ring is fixed
It is peripheral and opposite with permanent magnet in metal friction disk.After electromagnetic coil assembly dead electricity, metal friction disk takes off with belt pulley sucker
It opens, magnetic conduction drive ring cuts the magnetic field of permanent magnet and forms vortex flow so as to generate electromagnetic force at this time, and the electromagnetic force of generation drives
Metal friction disk and magnetic conduction drive ring and main shaft and impeller do low speed hysteresis rotation.
It is understood that metal friction disk is particularly important Force transmission parts in from the above, assume responsibility for main torque and pass
The effect of passing.And obviously the size of itself and belt pulley chuck surface frictional force determines stability that torque transfers and reliably
Property.However following problem is exposed in actual use：
1）It is well known that the frictional force size between two components is exactly component contact surface in addition to depending on pressure size
Size.But existing electromagnetic clutch water pump, the surface of metal friction disk（Frictional contact surface）Often all shaping is set
In respect of multi-turn magnetic conductive groove, the function of magnetic conductive groove is to coordinate enhancing vortex flow and magnetic field force, it is ensured that metal friction disk can be steady
Speed hysteresis rotation.But shortcoming is also evident from, and the presence of magnetic conductive groove reduces rubbing between metal friction disk and belt pulley sucker
Wipe contact area, reduce frictional force so that electromagnetic coil assembly obtain it is electric in the case of, metal friction disk and belt pulley sucker it
Between friction torque transmission stability and reliability substantially reduce.This is the place of suitable contradiction in conventional design, both needs to set
The magnetic conductive groove enhancing eddy current effects counted, but wish to eliminate surface magnetic conductive groove, enhancing when metal friction disk adsorbs simultaneously again
Its contact area, and then strengthen suction and torque transmission.
2）Known electromagnetic clutch water pump mechanism often obtains electric, metal friction disk in electromagnetic coil assembly
It adsorbs belt pulley sucker and transfers torque, since electromagnetic coil assembly is different from permanent magnet, adsorption capacity relies on current control, exists
Unstability.In addition the unreliability that known metal frictional disk torque recited above transfers, causes existing electromagnetic clutch
The global reliability and stability of pump working 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 above-mentioned known electromagnetic clutch water pump power to be substituted to transfer knot
Structure is accomplished to enhance stability and reliability that torque transfers, and then ensures the stability and reliability of entire pump working.
The content of the invention
