During intermeshing, substantial amounts of heat can be generated, the gear of retarder is lubricated using Driven Gear of Final Reduction Gear oil cold
But, i.e., the gear oil of rated capacity is added in automobile drive axle bag, in the main reducing gear course of work, by Driven Gear of Final Reduction Gear
The gear oil driven during rotation cools down the splash lubrication that Driven Gear of Final Reduction Gear carries out, this is that a kind of passive gear lubrication is cold
But mode, during the lubrication to Driven Gear of Final Reduction Gear, this passive mode is to lubrication oil mass, lubrication
Effect and the temperature of gear oil do not have any control and detection in real time, and there are the following problems：
1）Operating mode regardless of automobile main reducer, the amount for the gear oil that Driven Gear of Final Reduction Gear takes up are constant：When automobile primary subtracts
When fast device is in tick-over state, at this point, too many lubricating oil is not required for the gear of main reducing gear it is ensured that main reducing gear
It runs well, ensures the enough lubrications of gear, and under passive type lubrication, the gear oil that Driven Gear of Final Reduction Gear takes up is constant,
This gear oil quantity that lubrication has been resulted in act on is had more than needed, and causes to waste, meanwhile, gear carries superfluous lubricating oil and turns
It is dynamic, stir that oily resistance is larger, and energy loss is more；
2）When automobile main reducer is in low-temperature condition, at this point, the gear of main reducing gear is not required too many gear oil just right
Driven Gear of Final Reduction Gear carries out enough lubrication coolings, ensures that gear is run under safety and stability, still, passive lubrication profit
The sliding type of cooling, the gear oil that Driven Gear of Final Reduction Gear takes up is constant, this has resulted in the gear oil quantity mistake that lubrication acts on
It is surplus, it causes to waste, meanwhile, gear carries superfluous lubricating oil and rotates, and stirs that oily resistance is larger, and energy loss is more；
3）Specific aim cannot to be carried out to the highest gear engagement position of temperature effective under passive lubrication mode, when oil mass is very few
Property lubrication, can realize that effectively lubricating cools down when oil mass is excessive, but excessive gear oil mass increase it is main subtract gear stir oil
Resistance causes the main transmission efficiency that subtracts to decline.
Therefore, it is necessary to design a set of control system that active lubrication cooling is carried out to Driven Gear of Final Reduction Gear, use is minimum
Gear oil mass realize to the main effectively lubrication for subtracting gear, while the usage amount of drive axle bag gear oil is reduced simultaneously
Improve the main transmission efficiency for subtracting gear.
