Description
Technical field
The invention belongs to the Design of Auto Parts technical field, more particularly to a kind of drive shaft gum cover cooling device.
Background technology
In common horizontal forerunner's automobile, the environment temperature of engine shaft is generally determined by following factor：1、
Drive shaft and gas exhaust piping distance；2nd, gas exhaust piping temperature；3rd, flow field situation near drive shaft.In automobile engine nacelle, drive
Moving axis and gas exhaust piping are apart from close, and due to the limitation in space, the distance of the two is difficult to expand.In addition, with automobile fuel consumption mark
Accurate continuous improvement, gas exhaust piping temperature also accordingly increases, in the prior art, often by being set between drive shaft and gas exhaust piping
Heat shield is put drive shaft is wrapped up to stop that the heat that gas exhaust piping distributes causes directly to damage to the gum cover in drive shaft
Bad, for the gum cover material generally used at present for thermoplastic elastomer (TPE) TPE, the instantaneous heat resisting temperature of highest is 140 DEG C, works as automobile exhaust
When the heat that pipeline distributes makes the air themperature raising between heat shield and gum cover through heat shield, and between heat shield and gum cover
Air can not circulate, the air of high-temperature is gathered in around gum cover for a long time, when gum cover ambient temperature is more than 140 DEG C
Limit value, heat shield will fail, and gum cover is subject to damage.
Invention content
The purpose of the present invention is to provide a kind of drive shaft gum cover coolings that can effectively reduce drive shaft ambient temperature
Device.
To achieve the above object, the technical solution adopted by the present invention is：A kind of drive shaft gum cover cooling device, the drive
The side setting induced draft plate of the gum cover of moving axis, induced draft plate guiding air-flow blow around gum cover.
Compared with prior art, there are following technique effects by the present invention：In motion, extraneous wind or fan blow automobile
Wind can the ambient enviroment for leading into drive shaft through induced draft plate, the outside air of low temperature obtains the surrounding air of drive shaft
With circulation, while the environment temperature of gum cover in drive shaft can be reduced to realize the more preferable protection to gum cover.

Specific embodiment
With reference to Fig. 1-Fig. 5, the present invention is described in further detail.
A kind of drive shaft gum cover cooling device, the side setting induced draft plate 10 of the gum cover 21 of the drive shaft 20, air inducing
Plate 10 guides air-flow to be blowed around gum cover 21, and by the setting of induced draft plate 10, vehicle is when driving or when fan work is formed
Air-flow enter the ambient enviroment of drive shaft 20 via the guide function of induced draft plate 10, the outside air of low temperature makes drive shaft 20
Surrounding air circulated, while the environment temperature of gum cover 21 in drive shaft 20 can be reduced to realize the more preferable guarantor to gum cover 21
Shield improves the service life of gum cover 21.
Embodiment one
The induced draft plate 10 is arc plate, and the plate face of induced draft plate 10 overhangs from front to back, upwards, and induced draft plate 10 is arranged in drive
The front lower place position of moving axis 20 ensures that the extraneous air-flow formed blows to drive shaft 20 from Chinese herbaceous peony direction along induced draft plate 10 in this way
Ambient enviroment, and the flow path of air-flow is smooth bending path.
As one further preferred embodiment of embodiment：
The lower end of the induced draft plate 10 is fixed on the lower backplate 30 of engine, and the both sides vertically-arranged of induced draft plate 10 has flange
11, flange 11 is arranged in the intrados side of induced draft plate 10, and the width of induced draft plate 10 is sequentially reduced by lower end to upper end.In this way
Extraneous air-flow can be flow to along lower backplate 30 is smooth in induced draft plate 10, and the in addition setting of flange 11 can play air-flow poly-
Hold together effect, air-flow is made to concentrate in induced draft plate 10, when air-flow flows to upper end by the lower end of induced draft plate 10, the intensity of air-flow also can be because
Being gradually reduced for width of induced draft plate 10 and increase, so as to make extraneous air-flow more strong by 21 surrounding higher temperature of gum cover
Air-flow dispel, in addition, the vibration resistance of induced draft plate 10 is enhanced, prevent fatigue damage, reduce noise.
The bottom plate of the induced draft plate 10 protrudes out to form protrusive board 12 upwardly, and protrusive board 12 is rectangular along the bottom plate of induced draft plate 10
To arrangement, the front end of protrusive board 12 is extended at the lower edge of induced draft plate 10, the rear end of protrusive board 12 and the ontology of induced draft plate 10 it
Between intersection open up port 13, the plate 31 protruded out from bottom to top is staggeredly disposed on the lower backplate 30, the both ends of plate 31 are equal
The edge of lower backplate 30 is extended to, induced draft plate 10 is fixed on lower backplate 30 and plate 31 is connected to the lower section of protrusive board 12 and passes through
It is bolted fixation.When driving, extraneous air-flow along the upper face of lower backplate 30 in addition to that can enter induced draft plate 10 for vehicle in this way
Intrados, moreover it is possible to enter the intrados of induced draft plate 10 through port 13 along the lower face of lower backplate 30, increase the stream of external air flow
Path.
Embodiment two
The induced draft plate 10 is curved arc into U-shaped, and the opening that the upper/lower terminal side of induced draft plate 10 is formed is directed toward headstock side
To gum cover 21 is located in the U-lag chamber of induced draft plate 10, on the one hand, extraneous air-flow flows to induced draft plate 10 from Chinese herbaceous peony, and in air inducing
Along the U-shaped flowing of peripheral wall of gum cover 21 in plate 10, the air-flow of external world's lower temperature in this way will disperse higher around gum cover 21
The air of temperature realizes the reduction to 21 ambient temperature of gum cover；On the other hand, induced draft plate 10 is by gum cover 21 and gas exhaust piping
Keep apart, heat radiation that Engine exhaust pipeline distributes can be reduced to being directly affected caused by gum cover 21.
Further preferred embodiment as embodiment two：
Port 14 is opened up on the bottom plate of the induced draft plate 10, overhanging downwards at the back edge of port 14 has baffle 15,
Baffle 15 is in tilted layout from the front to the back.It is encountered when vehicle is when driving or the air-flow that is formed of when fan work is flowed after vehicle from Chinese herbaceous peony
After baffle 15, because the blocking air-flow of baffle 15 can change path, enter between induced draft plate 10 and drive shaft 20 through port 14 upwards
Space, the air-flow of extraneous lower temperature disperses the air of higher temperature in the space, so as to make gum cover 21 in drive shaft 20
Environment temperature reduce.
The edge of the upper head plate of the induced draft plate 10 has upwardly extended folded plate 16, and the first hole 161, position are opened up on folded plate 16
The second hole 17 is opened up in the bottom plate edge of the cover body 10 of 11 forepart of port, passes through bolt at first, second hole 161,17
The upper end of induced draft plate 10 is fixed on motor body upper and lower end and is fixed on engine protecting by connection, and such setting was both convenient for
The fixation of induced draft plate 10, and can guarantee that external air flow can enter gum cover 21 by the guiding of baffle 15 in flowing by port 14
Ambient enviroment.
Reinforcing rib is arranged in the rear plate face of the induced draft plate 10, is enhanced the structure of induced draft plate 10, prevents strong gas
Stream impact deforms.
