Abstract
The utility model relates to a kind of automobile engine cooling water pump combined driving device, and belong to machinery, electronic technology field, the cooling waterpump that described device can realize motor adopts electric drive and engine-driving two kinds of driving mode respectively.Rise in process at engine cold starting or heat, engine cooling water pump adopts electric drive mode, and the circular flow of water pump can be made to be zero or regulate arbitrarily within the specific limits, namely when engine coolant temperature is lower than 30 DEG C, water pump does not turn; When engine coolant temperature is between 30 DEG C to 95 DEG C, water pump is rotated by motoring, and water temperature is higher, and the rotating speed of water pump is higher, engine thermal thus can be made to rise rapidly, improve engine thermal efficiency; In engine high-temperature working procedure, namely when engine coolant temperature is higher than 95 DEG C, by motor Direct driver cooling waterpump, pump working therefore can be made reliable, reduce energy consumption.
Description
Technical field
The utility model relates to a kind of water pump combined driving device for motor car engine cooling, belongs to machinery, electronic technology field.
Background technique
Current motor car engine adopts water-cooling pattern mostly, and cooling liquid is by cooling waterpump pump circulation, and water pump is directly by engine-driving.This traditional water pump driving mode Problems existing is, the flow of water pump only with the rotation speed change of motor, instead of with the changes in demand of engine cooling.Such as after motor starts in the cold state, the liquid circulation flow that incipient stage needs is zero or very little, then the flow needed along with the rising of engine temperature just increases gradually, but in fact water pump circular flow is just larger in the incipient stage, so not only because the work of water pump large discharge makes the heat of motor play increased periods, exacerbate the wearing and tearing of motor, and reduce the thermal efficiency of motor.
For this problem, someone proposes the idea adopting electric water pump, and electric water pump can regulate arbitrarily according to the circular flow of the temperature of motor to cooling liquid, solves the problems referred to above preferably.But this mode creates a new problem, namely when engine high-temperature state needs larger, stable liquid circulation flow, adopt the mode of electric drive water pump, need to consume larger electric current, this not only adds the burden of the power-supply system of automobile, and adopt electric drive mode to need the mechanical energy of motor to become electric energy, mechanical energy is become to drive water pump converting electric energy by motor again, this is than much lower by motor Direct driver pump efficiency, because this increasing energy consumption.
Automobile engine cooling water pump combined driving device described in the utility model, during work, the cooling waterpump of motor can adopt electric drive and engine-driving two kinds of driving mode as required respectively, rise in process at engine cold starting or heat, engine cooling water pump adopts electric drive mode, the circular flow of water pump can be made to be zero or to regulate arbitrarily within the specific limits, engine thermal being risen rapidly, improves engine thermal efficiency; In engine high-temperature working procedure, by motor Direct driver cooling waterpump, make pump working reliable, energy consumption reduces.
Summary of the invention
The purpose of this utility model is to realize engine cooling water pump respectively by motoring and engine-driving.
The purpose of this utility model is realized by such as lower device: a kind of automobile engine cooling water pump combined driving device, is made up of engine coolant temperature sensor 1, relay 2, controller 3, direct current motor 4, water pump 5, magnetic clutch 6, axle 7, belt pulley 8.It is characterized in that water pump 5 can be driven by direct current motor 4, also can be driven through belt pulley 8, axle 7, magnetic clutch 6 by V belt translation by motor.
Accompanying drawing explanation
Accompanying drawing is the schematic diagram of the present embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated:
Engine coolant temperature signal can be transformed into electrical signal and deliver to controller 3 by described engine coolant temperature sensor 1; Controller 3 according to the signal of engine coolant temperature sensor 1, controls direct current motor 4 and work, or control relay 2 can work; Direct current motor 4, for driving water pump 5, is controlled by controller 3, can speed governing work; Relay 2, in order to control the circuit of magnetic clutch 6, engages when magnetic clutch 6 is energized, the power of motor can be passed to water pump 5 through belt pulley 8, axle 7, then be separated during magnetic clutch 6 power-off, cuts off transmission of power.
During the work of described device, controller 3, according to the signal of engine coolant temperature sensor 1, determines the driving mode of water pump 5, and controls corresponding device and realize different driving mode.Rise in process at engine cold starting and engine thermal, when engine coolant temperature is lower than 30 DEG C, controller 3 neither makes direct current motor 4 work, and also do not make magnetic clutch 6 work, water pump 5 does not turn; When engine coolant temperature is between 30 DEG C to 95 DEG C, controller 3 makes direct current motor 4 be energized work, relay 2 no electric circuit, and magnetic clutch 6 is separated, and water pump 5 is driven by motor 4, and water temperature is higher, makes the rotating speed of direct current motor higher; When engine coolant temperature is higher than 95 DEG C, controller 3 makes relay 2 be energized, and thus magnetic clutch 6 is energized work, makes direct current motor 4 power-off simultaneously, the power of motor reaches water pump 5 through belt pulley 8, axle 7, magnetic clutch 6, and now water pump 5 is by engine-driving.
