Description
Technical field
The utility model belongs to the Design of Auto Parts and manufactures field, is specifically related to a kind of oil cooler pressure relief device.
Background technique
The gearbox of vehicle is for be converted to the rotating force of the engine rotating all the time in the device of vehicle drive force in a direction, gearbox can be divided into manual transmission, automatic transmission case, the all kinds such as stepless gearbox, be provided with the various workpieces such as gear in these gearbox inside, for these workpieces are lubricated, clean, therefore in gearbox, contain a large amount of fluid, but in the course of the work, the heat engine oil producing because of parts is heated, thereby induced viscosity reduces, this can have a strong impact on the lubricated of fluid, cleaning performance, therefore just need to carry out cooling to the fluid in gearbox with oil cooler, in prior art in order to improve cooling effectiveness, the oil pressure that enters oil cooler is generally larger, and fluid can directly impact heat dissipating pipe, be easy to like this heat dissipating pipe to cause damage, in order to improve the compression resistance of heat dissipating pipe, therefore have to adopt some high-intensity materials to make heat dissipating pipe as copper or stainless steel etc., so not only increase the weight of oil cooler, and cause heat dispersion poor, cost cost is very high simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of oil cooler pressure relief device that can reduce the impact force of fluid to heat dissipating pipe.
For achieving the above object, the utility model provides following technological scheme: a kind of oil cooler pressure relief device, comprise the buffering oil pocket of the heat dissipating pipe two ends setting of oil cooler, described buffering oil pocket is enclosed and is formed by housing, described housing is provided with the first through hole and the second through hole, described the first through hole is communicated with the oil pocket of automatic transmission case by pipeline, and described the second through hole is communicated with heat dissipating pipe.
Technique effect of the present utility model is: at the leading portion of heat dissipating pipe, buffering oil pocket is set, has greatly reduced the surge pressure of fluid to heat dissipating pipe.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is that the solid that cushions oil pocket in the utility model splits structural representation;
Fig. 3 is the sectional view of buffering oil pocket.
Embodiment
As shown in Figure 1, a kind of oil cooler pressure relief device, comprise the buffering oil pocket 20 of the heat dissipating pipe 10 two ends settings of oil cooler, as shown in Figure 2,3, buffering oil pocket 20 is enclosed and is formed by housing 20a, and described housing 20a is provided with the first through hole 21 and the second through hole 22, and described the first through hole 21 is communicated with the oil pocket of automatic transmission case by pipeline, described the second through hole 22 is communicated with heat dissipating pipe 10, and described the first through hole 21 is mutually vertical with the opening direction of the second through hole 22.Generally, in order to improve the cooling effectiveness of oil cooler, the flow velocity of fluid that enters oil cooler is all higher, therefore the oil pressure in right heat pipe 10 can be higher, especially the oil inlet end of heat dissipating pipe 10 can directly be subject to the impact of fluid, so long impact likely causes heat dissipating pipe 10 to be out of shape, therefore the utility model arranges buffering oil pocket 20 at the two ends of heat dissipating pipe 10, buffering oil pocket 20 is enclosed cavity body structures, fluid can impact to discharge kinetic energy to the inwall of buffering oil pocket 20 after entering buffering oil pocket 20, then fluid can change the flow direction and finally enters in heat dissipating pipe 10, the burden that can greatly reduce like this heat dissipating pipe 10 extends its working life.
As shown in Figure 3, housing 20a comprises one section of buffering suface 25, described buffering suface 25 is positioned at the intersection of the reverse extending line of the opening direction of the first through hole 21 and the second through hole 22, described buffering suface 25 is to make the liquid stream that the first through hole 21 or the second through hole 22 pour in change gradually the inclined-plane or the curved surface that flow to, and the angle of the opening direction of this inclined-plane or curved surface and the first through hole 21, the second through hole 22 is obtuse angle or acute angle.Buffering suface 25 is exactly to be subject to the face that fluid directly impacts, this buffering suface 25 is arranged to inclined-plane or curved surface is directly to impact this face and then produce very large impact force with Vertical direction for fear of fluid, be arranged to inclined-plane or curved surface later the impact force of fluid have a process discharging gradually, can greatly improve like this maximum impact force that buffering oil pocket 20 can bear.
As shown in Figure 2, housing 20a comprises vertical and adjacent the first shell wall 23 and the second shell wall 24 mutually, described the first shell wall 23 and the second shell wall 24 are provided with the recessed shelly curved surface seamlessly transitting between two edges away from each other, the centre of curvature of described recessed shelly curved surface is positioned at buffering oil pocket 20 inside, described recessed shelly curved surface forms buffering suface 25, described housing 20a also comprises the sidewall 26 of two whiles perpendicular to the first shell wall 23 and the second shell wall 24, sidewall 26 with on the first shell wall 23 and the second shell wall 24, be perpendicular to one another and crossing two side edge, described the first shell wall 23, the second shell wall 24, buffering suface 25 and two sidewalls 26 enclose buffering oil pocket 20 jointly.
As shown in Figure 2,3, as preferred version of the present utility model, housing 20a is welded by an open type housing and one flat plate, described dull and stereotyped second shell wall 24 that forms, the edge of described flat board is provided with more than two buckling groove 27, the edge of the opening of described open type housing is provided with the projection 28 corresponding with buckling groove 27 positions, and described projection 28 forms clamping with buckling groove 27 and coordinates, the seam crossing welded seal between described flat board and open type housing opening.Above-mentioned open type housing and flat board all can be by punching press once-throughs, manufacture very convenient, be applicable to produce in enormous quantities.
