Description
Technical field
The utility model relates to a kind of sink, particularly relates to a kind of energy-saving heat radiating device for engineering vehicle.
Background technique
At present, on the vehicle on large engineering vehicle particularly hidrodynamic form chassis, when long-distance running, because the power of motor is larger, only the heat dissipation potential of forward fan is not enough, need to install water tank in addition additional to dispel the heat, the radiating mode of current water tank is generally large power, electrically motor (electric fan) or fluid motor-driven fan dispels the heat.Be that electric notor or oil hydraulic motor all need the extra engine power of consumption to drive, thus improve power consumption.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of energy-saving heat radiating device for engineering vehicle without power, energy efficient.
For reaching above-mentioned purpose, a kind of energy-saving heat radiating device for engineering vehicle of the utility model, described sink comprises one and is arranged at back pressure one-way valve between total oil return of engineering vehicle working connection and fuel tank, one is arranged at the piston motor on the power taking mouth of transfer case or vehicle bridge in engineering vehicle main transmission, described piston motor and described back pressure one-way valve are connected, described piston motor is also connected with a solenoid directional control valve, described solenoid directional control valve two exports and connects engineering vehicle working connection and a heat radiation motor respectively, described heat radiation motor is communicated with a fan leaf, the corresponding engine water tank of described fan leaf, described engine water tank is provided with a cooling-water temperature sensor, described cooling-water temperature sensor controls the switching of described solenoid directional control valve, for selecting entering of described piston motor, whether oil return communicates, thus control the work of heat radiation motor driving fan leaf.
The axle that produces of wherein said heat radiation motor connects described fan leaf.
Working principle: when vehicle in the process of moving, by comprising motor, gearbox and transfer case are at the tire of the certain rotating speed of interior main transmission transmission to each vehicle bridge, driving vehicle travels, simultaneously, be arranged on the power take-off gear in vehicle bridge or the power take-off gear on transfer case also can rotate with a certain speed, the reversing motor be connected on power taking mouth can be driven to rotate, now motor just becomes a pump, intake side is from the hydraulic oil of the certain back pressure of return opening inspiration band of working connection, by rotating, the pressure oil with certain pressure is exported from force feed mouth, thus drive heat radiation revolution, wheel rotation on the further output shaft driving heat radiation motor, thus the heat sinking function realized engine water tank.As long as the tire of vehicle is in rotation, the radiation fan of this water tank just can normally work, motivational drive that need not be extra, thus make use of the unnecessary rotary inertia produced when vehicle travels, and has saved energy consumption.
Back pressure one-way valve is arranged between total oil return of working connection and fuel tank, plays and produces certain back pressure to oil return, realizes allowing the piston motor hydraulic oil that inspiration is enough fully under slow-speed of revolution operating mode, does not produce and inhales empty and damage hydraulic element.
Piston motor is arranged on the power taking mouth of transfer case or vehicle bridge in engineering vehicle main transmission, as long as vehicle bridge can be rotated, then can drive this revolution, realize the function of its plunger pump, why adopt piston motor and directly do not adopt plunger pump, one of its reason is that the piston motor of same discharge capacity and function is generally cheap than plunger pump, and piston motor more can bear higher rotation speed; Two of reason is that piston motor all can bear Double-directional rotary, and common plunger pump then can not bear Double-directional rotary.
The Main Function of solenoid directional control valve is commutation function, realizes the switching of pressure oil output according to the demand for control of reality.
The Main Function of heat radiation motor is that it produces the rotation of axle drive blast fan, thus realizes the heat sinking function to engine water tank.
The Main Function of cooling-water temperature sensor is the temperature detecting engine water tank, utilizes this checkout value to control the working position of solenoid directional control valve.
When vehicle travels, the power taking mouth be arranged in transfer case or vehicle bridge drives piston motor to rotate, the hydraulic oil of rotation meeting before its inlet port inspiration back pressure one-way valve of piston motor, heat radiation motor is directly entered by solenoid directional control valve from its pressure oil port, thus drive heat radiation revolution, the blast fan of its output shaft also rotates with certain speed, plays to the effect of engine water tank heat radiation.
Wherein, the controlled conditions of solenoid directional control valve has two: the first, when the engine water tank temperature that cooling-water temperature sensor detects is reduced to lower than a certain setting temperature, solenoid directional control valve obtains electric commutation, after the pressure oil exported by piston motor is commutated by solenoid directional control valve, directly get back to its intake side, no longer enter heat radiation motor.Thus realize when a certain low temperature, heat radiation motor quits work, and only just starts working higher than during setting temperature at cooling-water temperature sensor checkout value.
Second, when vehicle starts to move backward, due to reverse gear and forward gears direction of rotation, therefore the sense of rotation outputting to piston motor is also contrary, so now allow solenoid directional control valve obtain electric commutation, realize motor and also directly can be drawn onto enough hydraulic oil from total return opening of system when counterrotating, in order to avoid the empty damage causing motor internal element inhaled by piston motor.Meanwhile, because reverse gear has speed limit, and backing time can not be oversize, thus engine water temperature can not on be too high, in order to cost-saving, do not consider to arrange hydraulic bridge and control to realize clockwise and anticlockwise.
The energy-saving heat radiating device difference from prior art that the utility model is used for engineering vehicle is that the utility model achieves following technique effect: the utility model is used for the energy-saving heat radiating device of engineering vehicle under advocating energy-saving and cost-reducing design concept at present, reduce the energy consumption of large engineering vehicle, do not affect the cooling requirements when long-distance running simultaneously, efficiently solve the shortcoming that when dispelling the heat motor operations, motor energy consumption raises.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
