Amount plunger displacement pump 3 oil-out is respectively communicated with temperature-sensitive overflow by temperature-sensitive overflow valve oil circuit control 8 and the pressure oil pipeline 12 to motor
The oil-in of valve 1 and the oil-in of fixed displacement motor 6, the oil-out of temperature-sensitive overflow valve 1 and the oil-out of fixed displacement motor 6 lead to respectively
Cross respective return line (9,13) and be communicated to fuel tank 7；The drain tap of axial variable plunger pump 3 is communicated to by drain line 11
Fuel tank 7.
During installation, axial variable plunger pump 3 connects electromotor 17, between electromotor 17 and heat exchanger 2 by change speed gear box 4
By two cooling oil paths (14,15) connection to form circulation cooling circuit therebetween；Described temperature-sensitive overflow valve 1 is arranged on
On heat exchanger 2, the output gas flow 16 of fan 5 is just to heat exchanger 2.
Described temperature-sensitive overflow valve 1 is open type temperature-sensitive overflow valve (KEV temperature-sensitive overflow valve), is the direct controlled type of a cone valve structure
Overflow valve, its rated pressure is in given boundary value and temperature proportional, the right structure qualification of its maximum pressure.In conjunction with Fig. 2 institute
Showing, described KEV temperature-sensitive overflow valve includes temperature-sensitive element 109, valve body 101, spool 104, valve seat 102, main spring 105, feedback
Spring 103, spring base 106, positioning sleeve 107, swivel nut 108 and sealing ring 110 and shoe cream room 113；Described valve body 101 is outside to be opened
There are described oil-in 111 and oil-out 112, valve body 101 center drilling；At the centrally disposed described valve seat 102 of valve body 101, valve seat
102 overcoats and described spool 104 tip surface install described feedback spring 103；The tip of spool 104 is towards valve body 101 head also
Contact with valve seat 102；One end of described main spring 105 connects the afterbody of spool 104, and the other end of main spring 105 connects described
Spring base 106 one end, spring base 106 other end connects with described shoe cream room 113；Described swivel nut 108 is socketed described temperature-sensitive element
109 and valve body 101 head；Positioning sleeve 107 is socketed valve body 101 lateral tail；At described valve body 101 afterbody and positioning sleeve 107
Belled position, swivel nut 108 are outside with valve body 101 afterbody belled position and positioning sleeve 107 is designed with described sealing ring 110.
The temperature-sensitive element 109 of temperature-sensitive overflow valve is arranged on heat exchanger 2, and temperature-sensitive element 109 is situated between according to the cooling recorded
The variations in temperature of matter and stretch, to main spring 105 and feedback spring 103 through spring base 106 pre-add compression stress；Temperature-sensitive overflow valve 1
According to the coolant temperature recorded, control pressure, axial variable plunger pump to the stroking mechanism one of axial variable plunger pump 3
3 provide flow to the variable displacement motor 6 driving fan 5 according to pressure；When the temperature of heat eliminating medium raises, drive turning of fan 5
Dynamic speed increases, and in contrast, when heat eliminating medium temperature is low, fan 5 velocity of rotation reduces；Owing to driving variable displacement motor 6
Axial variable plunger pump 3 controls with the temperature proportional of cooling medium, so be controlled fan 5 with temperature-sensitive overflow valve 1 can
Significantly to reach energy-conservation purpose.
Concrete, the inclined disc type axial variable plunger pump of this utility model, axial variable plunger pump 3 is by pressure oil pipeline
Being connected with fixed displacement motor 6, the output flow of axial variable plunger pump 3 is basically identical with the input flow rate of fixed displacement motor 6, by axially
Variable plunger pump 3 drives fixed displacement motor 6 to rotate, owing to the output flow of axial variable plunger pump 3 is scalable change, so
The input flow rate flowing to fixed displacement motor 6 is also transformable, thus affects the rotating speed of fixed displacement motor 6, it is achieved fixed displacement motor 6 and wind
Fanning the adjustability of 5 rotating speeds so that fan 5 rotating speed is unrelated with transmitter 17 rotating speed, fan 5 rotating speed is situated between with heat dissipation capacity, described cooling
Matter (such as water, hydraulic oil etc.) temperature and ambient temperature are relevant, and fan can the independently installed limit not changed by engine speed
Make, reduce the consumption of the energy.
In work process, the temperature-sensitive element of temperature-sensitive overflow valve 1 record the coolant temperature of heat exchanger 2 higher time, heat
The distance rod of quick element is overhanging, biasing springs seat, main spring and spool, and the tip of spool diminishes with the throttle clearance of valve seat, heat
The oil pocket pressure of quick overflow valve 1 oil-in rises, and the swashplate angle of driving axial Variable plunger pump 3 becomes big, axial deflection plunger
The output oil mass of pump 3 increases therewith, and the input flow rate of fixed displacement motor 6 increases thus drives the rotating speed of fan 5 to increase, and reaches heat
The effect of exchanger 2 cooling medium cooling, reduces the temperature of electromotor 17, it is ensured that electromotor 17 properly functioning then；Cooling
Medium temperature reduces, and the driving force of fan 5 decreases；If coolant temperature is too low, make the heating of temperature-sensitive element 109
Temperature is less than range of accommodation, and the pre-add compression stress of regulation main spring 105 eliminates, and feedback spring 103 is by shoe cream room 113 pressure release, storage
Oil in oil pocket 113 is back to fuel tank 7.
Therefore, this utility model element installing space is little, may be mounted at the optional position of vehicle；This utility model uses and becomes
Amount pump drives and remotely controls to adjust static pressure fan, uses temperature and pressure valve according to the temperature control variable pump of cooled medium
Pressure, the power that variable pump is consumed is automatically adjusted according to the needs of cooling, it is to avoid the power dissipation of fan, so that
The ability of cooling balances each other with the heat of generation.When electromotor reaches its required operating temperature and keeps temperature constant
Time, engine scuffing can be reduced, make engine efficiency reach optimum, reduce discharge.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and
Retouching also should be regarded as protection domain of the present utility model.
