Kind cooling system, by cylinder and the water jacket being formed in cylinder head, water pump and valve for compulsory circulative cooling water are controlled automatically
Coolant processed flows to the thermostat composition of radiator.In cooling system as described above, the flowing of cooling water is as follows：Engine
It recycles the cooling water heated and radiator is flowed by thermostat；Then, radiator is cooled down by the cold air of inflow cooling fan,
The cooling water cooled down by water pump is flowed back into engine by water pump to cool down engine.It is supplied from engine cold to thermostat
But a part for water is supplied to the other component of heater or throttle valve and the cooling water for supplying such as turbocharger
And after being heated or cooled, and via the circulation loop of the downstream side of revolving body inflow engine side.Hereinbefore, when
When engine is driven, water pump for compulsory circulative cooling water wheel rotor while making impeller while operating, by by
The rotation of rotor（Mechanical energy）Kinetic energy is supplied to cooling water, pressure energy to be converted into pressure in pump chamber by the centrifugal force of generation
Energy, to execute the pumping of cooling water.
However, water pump operates simultaneously with engine if as discussed above, then in the idling condition, when rotating at high speed, by
Cavitation erosion is generated in pump in the excessive rotation of water pump, this shortens the service life of pump bearing.In the above description, air pocket
Phenomenon refer to caused by the pressure drop of cooling water caused by cavitation air contained in cooling water and other from cooling water
In the gas that releases will produce noise, vibration and corrosion, this can cause material fatal damage.In addition, due to cooling
The driving of water and engine supplies simultaneously, so the preheating time of engine is elongated, exhaust discharge and fuel consumption increase.
Invention content
The present invention for overcome the deficiencies in the prior art, provide a kind of preheating time is short, prevent pump cavitation, minimize pumping
The power transmission of the vehicle water pump of loss.
To achieve the goals above, the present invention uses following technical scheme：The power transmission of vehicle water pump, including
Driving belt pulley, driven pulley, variable bindiny mechanism and engine are with there are one outer diameter portions for the driven pulley tool
With an inside diameter portion；The variable bindiny mechanism includes the first loose pulley and the second loose pulley and actuating
Device.
The outer diameter of first loose pulley is more than the outer diameter of second loose pulley, and the first loose pulley
Can be connect respectively with driving belt pulley and outer diameter portion, the second loose pulley can respectively with driving belt pulley and interior diameter diameter
Part connects, in the starting stage of engine, the first loose pulley and the second loose pulley speed belt wheel not with driving skin
Belt wheel is connect with driven pulley, then water pump shuts down, and shortens preheating time, to reduce discharge and improve fuel-economy
Property.
Further, the actuator includes two-way hydraulic cylinder, is projected into the First piston bar and of two-way hydraulic cylinder both sides
Two piston rods, the first loose pulley are mounted on first piston boom end, and the second loose pulley is mounted on second piston bar
End.
The two-way hydraulic cylinder have first pressure room and second pressure room, first pressure room be equipped with the first conduit, second
Balancing gate pit is equipped with the second conduit, and two-way hydraulic cylinder is connected to vacuum pump by the first conduit and the second conduit.
First conduit is equipped with the first valve, and second conduit is equipped with the second valve.
In conclusion starting stage of the present invention in engine, the first and second loose pulleys are not by drive belt
Wheel is connect with driven pulley, stops the operating of water pump, shortens preheating time, to reduce discharge and improve fuel economy,
In low-load part, with truckle than the first loose pulley be arranged between driving belt pulley and driven pulley
In high load part, greatly increase belt pulley than the second loose pulley be connected to driving belt pulley and slave end belt pulley,
By connecting belt pulley to adjust the discharge capacity of water pump according to operating condition, can be minimized prevents pump cavitation and pumping loss.
