Description
Technical field
The present invention relates to technical field of engineering machinery, especially a kind of cooling control system of driving bridge for engineering machinery.
Background technique
Driving bridge for engineering machinery be a kind of revolving speed that can change from speed changer positioned at driveline of construction machines end and
Torque, and pass them to the mechanism of driving wheel.Driving bridge for engineering machinery, including the main biography of drive axle with closed shell
Dynamic bridge packet, in being equipped with the differential mechanism and multiple intermeshing main drive gears being immersed in oil liquid in shell, when work main biography
Moving gear runs at high speed, and agitation oil liquid, which splashes, plays the role of the lubrication of main drive gear, but in real work, there is 1,
Since engineering machinery often runs at high speed or long-term high loaded process operation for a long time, the heat that such main drive gear operating generates
Amount is constantly transmitted in oil liquid, keeps the temperature of oil liquid higher and higher, with the raising of oil temperature, the viscosity of oil liquid can be increasingly
Dilute, the oil film being adhered on main drive gear is increasingly easily broken, and accelerates the abrasion of intermeshing main drive gear；2,
Since the capacity of oil liquid can excessively make to stir resistance increase, energy loss is caused, and in practice, in order to obtain the profit of gear entirety
Sliding effect, oil liquid must be set as not crossing the middle line of main drive gear, therefore the problem that the transmission efficiency for causing main drive gear is low.
Summary of the invention
The present invention provides a kind of driving bridge for engineering machinery cooling control system, which can solve existing engineering machinery and drive
Dynamic bridge run at high speed for a long time or long-term high loaded process in generated heat reduce the viscosity of its shell inner fluid and accelerate
The problem that oil liquid in the abrasion of main drive gear and its shell excessively causes the transmission efficiency of main drive gear low.
To solve the above-mentioned problems, the technical scheme adopted by the invention is that: this driving bridge for engineering machinery radiating control
System is equipped with the multiple phases being immersed in oil liquid including the drive axle main drive bridge packet with closed shell in the shell
The main drive gear mutually engaged offers oil inlet on the shell above the main drive gear, the shell
Electronic oil scavenge pump and radiator are successively arranged between oil outlet and the oil inlet；The automatically controlled end of the electronic oil scavenge pump passes through control
Device processed is connected with the temperature sensor for incuding the shell inner fluid temperature.
In above-mentioned technical proposal, more specific technical solution may also is that the controller includes processor and relay
Device；The signal output end of the processor is connected with the coil-end of relay, and the tip side of the relay is connected to described
On the power supply circuit at the electronic automatically controlled end of oil scavenge pump.
It is further: magnetic filter is equipped between the oil outlet of the shell and the electronic oil scavenge pump.
Further: the tip side of the relay is normally opened contact end.
Further: the oil outlet is set to the lower end of the shell.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages:
1, offer oil inlet since the present apparatus is located on the shell above main drive gear, the oil outlet of shell and oil inlet it
Between be successively arranged electronic oil scavenge pump and radiator；The automatically controlled end of electronic oil scavenge pump passes through controller and induction shell inner fluid temperature
Temperature sensor be connected；In work, temperature sensor is in real time monitored the intracorporal oil temperature of shell, when temperature sensor sense
When the temperature value that should be arrived is higher than the preset value in controller, which is fed back to controller, controller by temperature sensor
To instruction is issued after temperature information processing, power on electronic oil scavenge pump, cold oil is from the oil inlet above main drive gear
The surface for spraying main drive gear is directly cooled down and is lubricated to the main drive gear to run at high speed, not only maintains oil
The viscosity of liquid makes the oil film being adhered on main drive gear is durable not break, and slows down the abrasion of main drive gear, moreover, in electricity
Under the action of dynamic oil scavenge pump, after the high-temperature oil liquid flowed out from shell oil outlet is by radiator cooling, what is constantly recycled returns to shell
Body oil inlet cools down to main drive gear, will not have excessive oil liquid in shell, and the transmission efficiency of main drive gear is high.
2, since controller includes processor and relay；The coil-end phase of the signal output end of processor and relay
Connection, the tip side of relay are connected on the power supply circuit at the automatically controlled end of electronic oil scavenge pump；When work, processor output
Signal charges the coil-end of relay, is then closed the normally opened contact end of relay, enables electronic oil scavenge pump power on and turns
It is dynamic, realize control of the controller to electronic oil scavenge pump.
3, due to being equipped with magnetic filter between the oil outlet of shell and electronic oil scavenge pump；It plays to oil liquid demagnetization and filters out
The effect of impurity.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of the embodiment of the present invention.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings:
Driving bridge for engineering machinery cooling control system shown in FIG. 1, including the drive axle main drive bridge with closed shell 1
Packet, shell 1 is interior to be equipped with the multiple intermeshing main drive gear (not shown)s being immersed in oil liquid, is located on main drive gear
Oil inlet 1i is offered on the shell 1 of side, the lower end of shell 1 is equipped with oil outlet 1O；The oil outlet 1O and oil inlet 1i of shell 1 it
Between magnetic filter 2, electronic oil scavenge pump 3 and radiator 4 be successively arranged by oil pipe；The induction end of temperature sensor 5 is set to
Shell 1 is interior, incudes the temperature of 1 inner fluid of shell, and temperature sensor 5 passes through the automatically controlled end phase of controller II and electronic oil scavenge pump 3
Connection；Controller II includes processor 6 and relay 7；The signal output end of temperature sensor 5 and the signal of processor 6 are defeated
