The both ends that the derailleur advances oil pipe and derailleur play oil pipe are the straight tube, and the centre is the return bend, and the support is fixed in the straight tube section of one end, and the mouth of pipe of both ends straight tube all is equipped with the rubber end cap. The cold coupling assembly of this leak protection oil advances oil pipe with the derailleur and the derailleur goes out the middle design return bend of oil pipe, is difficult to remain the machine and adds the residue, stop up the rubber end cap for the mouth of pipe at both ends, make it guarantee in the transportation that the cold coupling assembly of oil does not get into the foreign matter, also guarantee the inside oil of automatic gearbox simultaneously and not because of leaking appears in reasons such as transportation, guarantee the clean and tidy degree of product reliability and production line. Set up rubber seal and by the location of bulging in the position with the assembly of oil inlet and oil -out, guaranteed the sealing performance of rigging position, can prevent also that fluid from leaking.
Description
Technical field
The utility model belongs to transmission for vehicles technical field, is specifically related to the oil-cooled tube connector assembly of speed changer.
Background technique
Oil-cooled tube connector assembly is the transition member of speed changer fluid and car load refrigerating module, and current automotive transmission oil-cooled tube joint is mainly metallic pipe coupling, is assembled by bolt or tapped hole and speed changer, and pipeline trend is main mainly with straight tube.Such design can solve speed changer oil cooling demand, but structural design is perfect not, there is certain hidden danger in assembly process.See Fig. 1, oil-cooled tube joint a is straight tube, and afterbody b adopts worm structure, reserves tapped hole coordinate with speed changer, and red copper pad c provides sealing while guarantee precompression.This Standard difficulty is comparatively large, and straight tube easily residual machine adds residue, and oil-cooled tube has assembled in transportation process can produce oil leak.
Summary of the invention
The problems such as the deficiency that prior art exists, the utility model discloses a kind of speed changer leakproof oil cooling pipe joint assembly, the oil liquid leakage that solution oil-cooled tube joint may occur in the processes such as assembling, transport.
The technical solution of the utility model is as follows:
A kind of speed changer leakproof oil cooling pipe joint assembly, it comprises speed changer oil inlet pipe, speed changer oil outlet tube and support, speed changer oil inlet pipe and speed changer oil outlet tube are fixed on support, support have the bolt hole be connected with speed changer, outside the oil inlet and outlet being installed on speed changer.The two ends of described speed changer oil inlet pipe and speed changer oil outlet tube are straight tube, and centre is bend pipe, and support is fixed on the straight length of one end, and the mouth of pipe of two ends straight length is all equipped with rubber plug.
Further, there is rubber seal the position that speed changer oil inlet pipe and speed changer oil outlet tube assemble with the filler opening of speed changer and oil outlet respectively elastic conjunction, and the outside of rubber seal is using the bulge of speed changer oil inlet pipe and speed changer oil outlet tube projection as location.
This leakproof oil cooling pipe joint assembly, by speed changer oil inlet pipe and speed changer oil outlet tube medium design bend pipe, is not easy residual machine and adds residue; Blocked by the mouth of pipe rubber plug at two ends, oil-cooled tube connector assembly does not enter foreign matter to make it ensure in transportation process, also ensures that the oil product of automatic transmission inside is not because leaking appears in the reasons such as transport, ensures the tidiness of product reliability and production line simultaneously.Rubber seal be set in the position of assembling with filler opening and oil outlet and located by bulge, ensure that the sealability of rigging position, also can prevent oil liquid leakage.
It is visible,
thisthe problems such as leakproof oil cooling pipe joint assembly passes through the mode increasing rubber plug, bend pipe process, the process of length of pipe cascade, the oil liquid leakage that solution oil-cooled tube joint may occur in the processes such as assembling, transport.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
See Fig. 2, oil-cooled tube connector assembly described in the utility model comprises speed changer oil inlet pipe 1, speed changer oil outlet tube 2, support 3, rubber plug 4 and rubber seal 6 etc.
See Fig. 2 and Fig. 6, speed changer oil inlet pipe 1 and speed changer oil outlet tube 2 one long one slightly short, still assembling work can be completed smoothly when this design can ensure that assembly space is narrow and small, the two ends of speed changer oil inlet pipe 1 and speed changer oil outlet tube 2 are straight tube, intermediate portion is bend pipe, the angle of bend pipe 130 °, elbow radius R35mm, can complete processing by same set of molds.The straight length at oil pipe two ends is all designed with bulge 5, adopts flange design.The two ends mouth of pipe of oil pipe is equipped with rubber plug 4, and the inwall of rubber plug 4 and the straight length cylindrical interference fit of oil pipe, ensure that no-sundries enters bend pipe inside in transportation process, prevents oil leak simultaneously, prevent from coming off in transportation process.Rubber plug 4 being reserved handle 41, conveniently having removed plug when assembling.Speed changer oil inlet pipe 1 and speed changer oil outlet tube 2 pass through the parallel welding of support 3, especially by oxy-hydrogen welding process.
See Fig. 3, Fig. 4 and Fig. 5, support 3 uses bolton with automatic transmission 7 by bolt hole 31 reserved on support 3.Rubber seal 6 is coordinated by automatic transmission 7 casing preformed hole and oil-cooled tube connector assembly, the straight length cylindrical interference fit of rubber seal 6 and speed changer oil inlet pipe 1 and speed changer oil outlet tube 2, using bulge 5 side as location, adopt interference fit equally with oil-cooled tube jiont treatment hole reserved on speed changer 7, thus ensure assembling complete after oil product can not from the leakage of oil of product junction plane, rubber seal 6 adopts fluorine rubber as raw material.
See Fig. 3 and Fig. 4, the utility model ensure that the difference H2 between automatic transmission oil discharge screw 8 to the height H 1 and the inner fluid height H 3 of automatic transmission of oil-cooled tube joint oil product outlet extreme lower position is greater than 5mm, and rubber plug 5 is not removed in transportation process, thus ensure that the oil product of automatic transmission 7 inside is not because leaking appears in the reasons such as transport, ensures the tidiness of product reliability and production line.
