Abstract
The present invention aims at providing a shielding device for exhaust pipes of motorcycles. Time for assembly can be reduced through low cost and simple structure; simultaneously, the shielding effect on an exhaust pipe of a motorcycle can be ensured, and the problems of foreign object crash and noise can be avoided. The shielding device for exhaust pipes of motorcycles of the present invention is provided with a shielding member, and is characterized in that the shielding member extends from an engine body member to an exhaust pipe; when people views the shielding member from the top part, the shielding member extends to the position which is nearer to the outer side of a motorcycle body than the exhaust pipe.
Description
Technical field
The present invention relates to a kind of suitable use and on the motor bike of various types, can cover the freeing pipe masking device of the motor bike that freeing pipe uses.
Background technology
General motor bike utilizes a freeing pipe, engine institute exhaust gas discharged is directed to silencer after, be expelled to the outside again.Therefore engine institute exhaust gas discharged temperature may after a period of time, although be subjected to the obstruct of freeing pipe tube wall, still can make the freeing pipe surface temperature rise in exhaust circulation pipe up to hundreds of degree Celsius.For this problem, general at present motor bike on the market, all adopt a kind of freeing pipe masking device to solve, it is for as shown in Figure 6, at first a door type metal piece 62 that is formed with several screw holes is fixed on the freeing pipe 61, by screw 64 shield 63 is locked on the door type metal piece 62 again.And, cause the temperature of shield 63 to rise because the heat of freeing pipe 61 can conduct on the shield 63 via metal piece 62 and screw 64, therefore must between screw 64 and shield 63, add plural layer pad 65, with the conduction of trap heat.
In addition, because heat is except conducting on the shield 63 via metal piece 62 and screw 64, also can be in the mode of radiation from freeing pipe 61 to shield 63 direct radiations, therefore more have one deck heat insulation foam or aluminium foil 66 etc. are set below shield 63, with the more effectively conduction of trap heat, and intercept from the heat of freeing pipe 61 to shield 63 direct radiations.
As mentioned above, in the previous motor exhaust pipe for vehicle masking device of this kind, owing to must between screw 64 and shield 63, add plural layer pad 65, and several screw holes of excavation with screw 64 shield 63 and pad 65 are locked on the ㄇ font metal piece 62, so its erecting work are numerous and diverse again on the narrow ㄇ font metal piece 62 of fabric width, degree of difficulty is also very high, cause its manufacturing cost to improve, and the assembling operation time is long and complicated, is its shortcoming.
In addition, the structure that locks with screw again behind several layers pad and the plate lamination because the previous motor exhaust pipe for vehicle masking device of this kind is served as reasons, be under the vibrational state for a long time, joint between each member can get loose gradually, so that can rock because of vibration during motorcycle driving, and constantly produce noise.

The specific embodiment
Following reference is graphic, describes embodiments of the present invention in detail.
At first please refer to Fig. 1 and Fig. 2, Fig. 1 is the lateral plan with motor bike of freeing pipe masking device 1 of the present invention.Fig. 2 (a) is the amplification plan view of the freeing pipe masking device part of Fig. 1, and Fig. 2 (b) is its front elevation.
As shown in Figure 1, it possesses a shading member 1 freeing pipe masking device of the present invention, and shading member 1 is to be arranged to from engine body member 2, and for example the fan drum of engine partly rises to freeing pipe 3 and extends.In order to cover freeing pipe effectively to prevent foreign collision, shown in the amplification plan view of Fig. 2 (a), shading member 1 is to form when being overlooked by the car body top, is formed up to the car body outside part more inclined to one side than freeing pipe 3.
The material of shading member 1 can be resin or metallic material, but the screening effect of resin material is better.Though metallic material is a Heat Conduction Material, but owing to as prior art, it directly is not locked on the freeing pipe 3 among the present invention, therefore high heat can be directly conducted on the shading member 1 that metallic material makes by freeing pipe, and only there is a little heat can be radiated to via the mode of radiation on the shading member 1 that metallic material makes, it is very low that it makes that the temperature of the shading member 1 that metallic material is made rises, and therefore the material of shading member 1 of the present invention also can be resin or metallic material.
The formation of shading member 1 can be used a mold and integrally formed with engine body member 2, or forms after the independent individuality, is locked on the engine body member 2 by screw 4 again.
According to the present invention, no matter be that shading member 1 and engine body member 2 is integrally formed, or shading member 1 is locked on the engine body member 2 by screw 4, all can not need as the prior art in order to intercept from freeing pipe 3 via the high heat of screw 4 to the shading member conduction, and the time and the cost that are spent several layers pad and heat insulation foam etc. must be locked in step between screw and shield the time.
Fig. 3 (a) is the cutaway view of a set-up mode of freeing pipe masking device of the present invention, and Fig. 3 (b) is its front elevation.Shown in Fig. 3 (a), shading member 1 of the present invention can be arranged to from engine body member 2 and almost parallel ground, ground to extend to the outside part more inclined to one side than freeing pipe 3 to the car body outside.Fig. 4 (a) is the cutaway view of another set-up mode of freeing pipe masking device of the present invention, and Fig. 4 (b) is its front elevation.Shown in Fig. 4 (a), shading member 1 of the present invention also can be arranged to extend to the outside part more inclined to one side than freeing pipe 3 from engine body member 2 oblique freeing pipes 3.
Shading member 1 in the set-up mode of Fig. 3 and Fig. 4 all is to form the skeleton type member, but shading member of the present invention 1 also can form the full slice system member.Fig. 5 (a) is the cutaway view of the another set-up mode of freeing pipe masking device of the present invention, and Fig. 5 (b) is its front elevation.Shown in Fig. 5 (b), shading member 1 of the present invention forms full slice system, therefore, and shown in Fig. 5 (b), shading member 1 can be arranged to extend to the car body outside from engine body member 2 and almost parallel ground, ground, and along the profile of freeing pipe 3 and with the profile of freeing pipe 3 coatings.In addition, can form a plurality of louvres 5 on the shading member 1,, the heat of coming from freeing pipe 3 radiation can be dispelled the heat, suppress the rising of shading member 1 temperature by these louvres 5.
Technology contents of the present invention and technical characterstic disclose as above, yet the those skilled in the art still can be based on the teaching of the invention described above and announcement and done all replacement and corrections that does not deviate from spirit of the present invention in the motor bike of various types.Therefore, protection scope of the present invention should be not limited to motor bike pattern shown in this specification sheets or the content that embodiment disclosed, and should comprise various do not deviate from replacement of the present invention and corrections, and is contained by above solution.
