Abstract
The utility model relates to a wind -guiding reducing fever engine lower protective plate, include by last face, down the face, connect the lower backplate and the guide duct of the echelonment formed on the inclined plane, the connection inclined plane on have a guide duct connecting hole, guide duct detachably connect in the guide duct connecting hole. The utility model discloses a wind -guiding reducing fever engine lower protective plate increases a guide duct that has the wind -guiding effect on the engine lower protective plate under traditional design. The guide duct is the design of branch spare with engine lower protective plate, fixes the guide duct on engine protection plate through engineering structure is fixed. This has very big advantage to same platform series motorcycle type, when starting the machinery room heat dissipation to reach the requirement, may not use the increase guide duct, does not reach when requiring when the machinery room heat dissipation, and engine lower protective plate gets rid of the guide duct that the closing cap face just can embolia the increase as long as follow the line that weakens, reaches the purpose of a dual -purpose.
Description
Technical field
This utility model relates to electromotor air guide structure, is specifically related to engine lower guard board.
Background technology
Along with the raising day by day of people's living standard, the requirement of automobile is also stepped up by people, is not only and has city and ride instead of walk function, additionally it is possible under the conditions of severe road conditions, automobile can stably travel.If in the case of hill path road conditions are very severe, owing to PTU (power transition components, powertransferunit) moment of torsion is big, heat dissipation capacity is high, causes internal heat to disperse in time, and internal oil temperature is the most higher, and PTU oil temperature may be beyond accepting limit value.
But present backplate under machine of sending out only protects vehicle chassis component not destroyed by foreign material in road conditions, but affects again the heat radiation bottom enging cabin simultaneously.Under specific dynamic property resource, PTU high oil temperature may inevitably produce the problems such as noise is excessive, internal temperature is too high, vibrated play.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one needs for various and heat radiation, it is possible to adjust backplate under the wind-guiding fall thermo-motor that heat radiation is tactful.
For reaching above-mentioned utility model purpose, backplate under a kind of wind-guiding fall thermo-motor is provided, including the stair-stepping lower backplate being made up of upper face, lower face, connection inclined-plane and guide duct, guide duct connecting hole, described guide duct is had removably to be socketed in guide duct connecting hole on described connection inclined-plane.
Preferably, having side support, lower face to fix screw pole in described guide duct side, guide duct side support is fixed on the screw pole of lower backplate after accessing connecting hole by described guide duct set by screw.
Preferably, described guide duct connecting hole has capping, cover and be connected by capping line of weakness with connecting hole edge.
Preferably, described guide duct has two side supports, and two side supports are positioned in the dislocation of guide duct heteropleural.
Lower backplate passes through upper face, lower face and connection inclined-plane composition, connect in inclined-plane and have a connecting hole, connecting hole is socketed for guide duct, connecting hole edge connects capping by capping line of weakness, can take off along capping line of weakness when needing, screw pole is had on lower face, screwed hole is had on guide duct side support, guide duct can be fixed on lower face by screw, and owing to lower backplate is forge piece of step type structure, can ensure that when guide duct is arranged on lower face the mouth of pipe of guide duct overlaps in access guide duct connecting hole naturally, realize removably connecting the function of guide duct on lower backplate.
Backplate under wind-guiding of the present utility model fall thermo-motor, the engine lower guard board under traditional design thinking increases a guide duct with wind-guiding effect.Guide duct and engine lower guard board are bulk-breaking designs, are fixed on engine protecting by guide duct by engineering structure is fixing.This has the biggest advantage for identical platform series vehicle, when engine bin heat radiation reach requirement time, guide duct can be increased without, when cabin heat radiation do not reach require time, engine lower guard board just can increase guide duct, reach the purpose of a dual-purpose.The beneficial effects of the utility model are the innovations that traditional design is used inwardly, are to supplement the utilization of backplate under conventional engines.Meet the needs of a lot of vehicles on existing market.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
5. according to a kind of wind-guiding shown in Fig. 1 to Fig. 5, backplate under thermo-motor drops, including the stair-stepping lower backplate 1 being made up of upper face 11, lower face 12, connection inclined-plane 13 and guide duct 2, guide duct connecting hole, described guide duct 2 is had to be detachably connected in guide duct connecting hole on described connection inclined-plane 13.Removably connecting and have side support 21 in being embodied as guide duct 2 side, lower face 12 is fixed with screw pole 14, guide duct side support 21 is fixed on the screw pole 14 of lower backplate 1 after accessing connecting hole by described guide duct 2 set by screw.Guide duct 2 has two side supports 21, and two side supports 21 are positioned in the dislocation of guide duct 2 heteropleural.Capping 5, capping 5 is had to be connected by capping line of weakness 51 with connecting hole edge on described guide duct connecting hole.Lower backplate 1 is by upper face 11, lower face 12 and connection inclined-plane 13 form, connect in inclined-plane 13 and have a connecting hole, connecting hole is used for connecting guide duct, connecting hole edge connects capping 5 by capping line of weakness 51, can take off along capping line of weakness 51 when needing, screw pole 14 is had on lower face 12, screwed hole is had on guide duct side support 21, guide duct 2 can be fixed on lower face 12 by screw, and owing to lower backplate 12 is in forge piece of step type structure, can ensure that when guide duct 2 is arranged on lower face 1 mouth of pipe of guide duct 2 overlaps in access guide duct connecting hole naturally, realize removably connecting the function of guide duct 2 on lower backplate 1.
Available engine protective plate has guide functions, therefore can depend on this part design guide duct.Certainly, if engine lower guard board does not have guide functions, then need by CFD analytical calculation means primary Calculation air-out to, thus on this basis, reasonable in design is tubular, it is to avoid the hidden danger and the wind pipe wall shape unreasonable generation resistance that are whirled up after air-flow inlet pipe and reduce the risk of wind speed.In the claimed range of rational wind-guiding face, it is ensured that reasonably intake, to reach to meet air intake cooling requirement.Flowmaster is utilized can effectively to calculate the area in theoretical air port, preliminary effectively solution wind-guiding areal calculation requirement.Flowmaster solution flow process.Being analyzed by CFD, the length of guide duct has an impact effect to wind speed: tubular long, and tube wall environment produces loss to the meeting of wind speed and air quantity, thus reduces last air output and go out wind velocity.Therefore, in effective spatial dimension, the length shortening airduct as far as possible is highly desirable to.
Below the preferred embodiment created this utility model is illustrated, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make modification or the replacement of all equivalents on the premise of this utility model creative spirit, and these equivalent modifications or replacement are all contained in the application claim limited range.
