Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
From a kind of structural representation of device for automobile main reducer radiating of Fig. 1 embodiment of the present invention, the hair
It is bright including engine radiator 1, water inlet pipe 2, outlet pipe 3, oil cooler 4, the bonnet 5 on main reducing gear 6 and main reducing gear 6；
Engine radiator 1 is original assembly on vehicle, is mainly used in engine cool.The recirculated water cooled down through engine radiator 1,
Enter by water inlet pipe 2 in oil cooler 4, the lubricating oil in main reducing gear 6 is with the cooling water in oil cooler 4 in radiating fin
11st, heat exchange is completed at oil cooler fuse 12, the heat of lubricating oil is taken away, completes the cooling water of heat exchange, then pass through outlet pipe 3
Into in engine radiator 1, circulation is completed.Oil cooler 4 is arranged on the bonnet 5 of main reducing gear 6, is fixed by nut 10；
Nut 10 plays a part of sealing with pad 8 simultaneously, prevents the lubricating oil in main reducing gear 6 from overflowing；Oil cooler is by sealing spiral shell
Bolt is fixed with decelerator lid, and without being further added by fixed structure, fixed form is simple；4 u-shaped arrangement of oil cooler, oil cooler 4
Water inlet 9 and delivery port 10 connect respectively at water inlet pipe 2 and outlet pipe 3；It is disposed with the oil cooler fuse 12 of oil cooler 4 a lot
Radiating fin 11, for increasing area of dissipation, improve radiating efficiency.
The present invention can optimize assembly internal lubrication under conditions of the original arrangement of vehicle and installation environment is not changed
Oily temperature in use, improves the service life of assembly, further improves the reliability of vehicle while has widened the use of vehicle
Condition, such as high bad working environments of big load, environment temperature, have very high versatility and practicality.
A kind of vehicle main retarder heat dissipating method disclosed by the invention by oil cooler 4 by being arranged in main reducing gear bonnet 5
On, guarantee oil cooler 4 oozes in gear lubricant completely, and oil cooler inlet and outlet are connected with engine radiator by water pipe；Oil
Water inside cooler is the recirculated water after engine radiator cools down.It is the gear lubricant of assembly outside oil cooler, lubricates
The heat of oil is transmitted in the cooling water inside oil cooler by heat exchange, and heat dissipates eventually through engine radiator.
Because the radiator, Water circulation hydrodynamics source for the main radiating of slowing down of vehicle are that original engine dissipates on vehicle respectively
Hot device, engine water pump, so without individually increasing device, therefore do not interfere with car using the heat dissipating method and device of the present invention
Arrangement and performance, while the oil cooler is fixed by sealing bolt and decelerator lid, without being further added by fixed structure,
Fixed form is simple.Oil cooler small volume, it is compact-sized；Radiating fin is disposed with the outside of oil cooler, increases area of dissipation, is improved
Radiating efficiency, main reducing gear lid described in increase heat dissipation capacity need to only reserve the installing space of oil cooler, and associated pipe passes through hole；
Present invention reduces the temperature in use of assembly internal lubrication oil, optimizes thermal environment inside main gearbox assembly, improves assembly
Service life, further improve reliability of the vehicle under worst hot case.Increase oil cooler device, energy in main reducing gear
Suitable for the bad working environments that big load, environment temperature are high while structure is not changed, the performance of vehicle is improved, greatly
The use range for having widened vehicle, there is very big versatility and practicality.
It should be appreciated that the foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not
Be confined to this, any those skilled in the art disclosed herein technical scope in, the change that can readily occur in
Or replace, it should all be included within the scope of the present invention.
