Description
Technical field
The present invention relates to a kind of planetary gear type water pump, is filled more particularly, to a kind of planetary gear type pump motor axis connection
Put, belong to automobile engine manufacturing technology field.
Background technology
The widely used mechanical water pump of water circulation system or electronic water pump of automobile engine.Traditional mechanical water pump is to pass through
Belt is directly connected to engine crankshaft, and pump capacity is determined by the rotating speed of engine, and the flow of mechanical water pump is according to hair
What the maximum heat dissipation capacity needed for motivation designed, when engine work, rotating speed is high, thus the flow of water pump is excessive, starts
Machine is easily cooled excessively, and mechanical water pump the flow of water pump can not be adjusted according to engine operating condition.Due to mechanical water
The power of pump comes from engine, if engine stall, water pump also stops operating therewith, and now engine will
Heat persistently is transmitted to coolant, coolant may seethe with excitement, and can not realize the rear cooling to cooling system.Electronic water pump can be with
Pump capacity is adjusted by control system, because the power of electronic water pump comes from motor, in engine stall
After electronic water pump can be controlled still to work, cooled down after realization.But the shortcomings that electronic water pump is that stability is poor, and electronic water
The electric energy of pump comes from a part for engine crankshaft output Effective power, and its energy development of evil in febrile disease efficiency is low, and generally only 60% or so.
In order to overcome existing machinery water pump to be adjusted, can not realized pair to the flow of water pump according to engine operating condition
The rear cooling of cooling system, and the deficiency that the stability of electronic water pump is poor, energy development of evil in febrile disease efficiency is low, applicant is with regard to one
Plant changeable flow planetary gear type pump technology scheme application patent protection.The changeable flow planetary gear type water pump being capable of root
The flow of water pump is adjusted according to engine operating condition；After engine stop operation, water pump can be driven by motor to hair
Motivation cools down after implementing.But when the motor of engine stop operation and water pump breaks down and can not run well, it is impossible to
Cooling reduces system temperature after implementing in time to engine, causes the thermic load of engine-cooling system part to increase, cylinder cap is held
The pressure received rises, and deforms cylinder cap.
The content of the invention
In order to overcome existing for existing changeable flow planetary gear type water pump in cooling procedure after implementing to engine, one
The motor of denier water pump breaks down when can not run well, it is impossible to which cooling reduces system temperature after carrying out in time, causes to start
