Summary of the invention
The technical problems to be solved in the utility model is: provide automatic transmission fluid after a kind of automatic transmission pressure release to be difficult for the automatic transmission cooling system that refluxes.
In order to solve the problems of the technologies described above, the utility model comprises automatic transmission and oil cooler, be provided with oil groove and oil pump in the automatic transmission, oil groove and oil cooler connect into a circulating oil path by oil pump, oil inlet pipe and return tube, be equipped with the choked flow pipeline section on described oil inlet pipe and the return tube, the choked flow pipeline section is higher than oil cooler.
For the ease of making, described choked flow pipeline section is the n font, and the horizontal segment of n font is higher than oil cooler.
In order to improve cooling effect, described oil cooler comprises oil cooler A and oil cooler B, oil cooler A and oil cooler B interval are arranged, the outlet of oil cooler A is connected import and is connected by high-pressure oil pipe with oil cooling B, oil inlet pipe connects the import of oil cooler A and the outlet of oil pump, and return tube connects outlet and the oil groove import of oil cooler B.
For the ease of refueling to oil cooler, the outlet of described oil cooler A is connected with an end of high-pressure oil pipe by hollow bolt, the import of oil cooler B is connected the other end and is connected by threeway with high-pressure oil pipe, the import of oil cooler B and the other end of high-pressure oil pipe are connected on the mouth of pipe of threeway by a hollow bolt respectively, and the threeway another one mouth of pipe is provided with bleeder screw.Open the bleeder screw venting during oiling.
The beneficial effects of the utility model are: the utility model is by setting up the choked flow pipeline section, in the situation of the mounting point that does not change automatic transmission and oil cooler, can increase the automatic transmission fluid resistance that refluxes from oil cooler to automatic transmission, prevent its backflow, the oil spilling problem of automatic transmission when well having solved automatic transmission oil cooler and automatic transmission and just arranging, solved that the automatic transmission oil mass that causes because of oil spilling is very few, oil temperature is too high, the automatic transmission that then causes burns out problem.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, oil cooler A, 2, oil cooler B, 3, oil cooler A import, 4, oil cooler A outlet, 5, high-pressure oil pipe, 6, oil cooler B import, 7, oil cooler B outlet, 8, the N-shaped metal bends, 9, return tube, 10, N-shaped metal bends, 11, oil inlet pipe, 12, elbow bend, 13, automatic transmission, 14, the automatic transmission oil outlet, 15, the automatic transmission return opening, 16, elbow bend, 17, oil pump, 18, oil groove.
Embodiment
A kind of specific embodiment as shown in Figure 1, it comprises oil cooler A1, oil cooler B2 and automatic transmission 13, is provided with oil pump 17 and oil groove 18 in the automatic transmission 13.Automatic transmission 13 is provided with automatic transmission oil outlet 14 and automatic transmission return opening 15.Oil pump 17 connects automatic transmission oil outlet 14 and oil groove 18, and automatic transmission return opening 15 connects oil groove 18.
Automatic transmission oil outlet 14 connects oil cooler A import 3 by oil inlet pipe 11, one end of oil inlet pipe 11 is provided with N-shaped metal bends 10, the other end of oil inlet pipe 11 is provided with elbow bend 12, and elbow bend 12 is connected with automatic transmission oil outlet 14, and N-shaped metal bends 10 is connected with oil cooler A import 3.
Oil cooler A outlet 4 is connected with oil cooler B import 6 by high-pressure oil pipe 5.Utilize hollow bolt with 5 one sections of high-pressure oil pipes fixedly in the oil cooler A outlet 4, the other end that oil cooler B import 6 is connected with high-pressure oil pipe connects by threeway, the other end of oil cooler B import 6 and high-pressure oil pipe 5 is connected on the mouth of pipe of threeway by a hollow bolt respectively, and the threeway another one mouth of pipe is provided with bleeder screw 5.
Automatic transmission return opening 15 and oil cooler B outlet 7 is connected by return tube 9.One end of return tube 9 is provided with N-shaped metal bends 8, and the other end of return tube 9 is provided with elbow bend 16.Elbow bend 16 is connected with automatic transmission return opening 15, and N-shaped metal bends 8 is connected with oil cooler B outlet 7.
Horizontal pipeline section in the middle of N-shaped metal bends 8 and the N-shaped metal bends 10 all is higher than two oil coolers.
When automatic transmission 13 runs well, fluid in the oil groove 18 of automatic transmission 13 is pressed among the oil cooler A1 by elbow bend 12, oil inlet pipe 11, N-shaped metal bends 10 under oil pump 17 effects, at first in oil cooler A1, cool off, the automatic transmission fluid of preliminary heat radiation is entered among the oil cooler B2 by high-pressure oil pipe 5 by oil cooler A1 outlet, after in oil cooler B2, cooling off, enter automatic transmission return opening 15 by N-shaped metal bends 8, return tube 9, elbow bend 16, realize a cool cycles.After automatic transmission 13 is out of service, pressure in the automatic transmission is by the exhaust port pressure release, automatic transmission is advanced, the pressure of return tube inner fluid is higher than the pressure in the automatic transmission, therefore advance, the return tube inner fluid refluxes to the lower automatic transmission of pressure, pressure in the automatic transmission oil cooler is higher than the pressure in the automatic transmission, so trend of the oriented automatic transmission backflow of the fluid in the automatic transmission oil cooler, but be back to N-shaped metal bends 10 or N-shaped metal bends 8 places, the pressure difference deficiency is crossed the transverse tube of N-shaped metal bends so that fluid is climbed, and make fluid stop to reflux, advance, the backflow of return tube inner fluid and vent pressure release make automatic transmission, metal bends, high-pressure oil pipe, pressure in the automatic transmission oil cooler reaches a new balance, and keep this balance, prevented effectively that fluid in the oil cooler from refluxing in the automatic transmission and the oil spilling that causes.
