Abstract
The utility model discloses an air inlet pipe of a motorcycle engine, which comprises an air inlet pipe body. One end of the air inlet pipe body is provided with a connecting flange connected with an engine cylinder head, an aluminum insert is assembled in the connecting flange, a heat-insulation cushion is arranged outside the aluminum insert, and the aluminum insert, the heat-insulation cushion and the connecting flange are fixed through bolts. A sealing ring is assembled between the aluminum insert and the heat-insulation cushion, and a sealing ring is assembled on the outer end face on the heat-insulation cushion connected with the engine cylinder head. Due to the structure, the heat-insulation cushion is additionally arranged on the outside of the aluminum insert and accordingly contacts with the engine cylinder head, and the aluminum insert is prevented from directly contacting with the engine cylinder head. The heat-insulation cushion can insulate most heat on the engine cylinder head, and heat transferred to the aluminum insert is little, accordingly, a rubber portion of the air inlet pipe is prevented from aging, hardening or losing elasticity due to over-high temperature, the service life of the air inlet pipe is prolonged.
Description
Technical field
The utility model relates to a kind of motorcycle accessories, is specifically related to a kind of motorcycle engine suction tude.
Background technique
On the former motorcycle; The suction tude that is used for connecting Carburetor and motor generally is full aluminum casting, because the temperature of engine cylinder head is very high during work, the capacity of heat transmission of aluminium is very strong again; Thereby make suction tude link to each other with Carburetor the end temperature usually too high; Influence the normal atomizing of fuel oil, full-power circuit is affected, engine consumption is high.At present a lot of motors begin to adopt the suction tude of rubber material, and on the adpting flange that suction tude and engine cylinder head link, the aluminium inserts are set, but this has brought new problem again; Because the aluminium inserts directly contacts with engine cylinder head; Through the heat of aluminium inserts transmission be easy to make the rubber part of suction tude aging, hardening and following the string, even breach appears, under the influence of engine luggine; Be easy to shattered, thereby influence its working life.
Summary of the invention
To the deficiency of existing technology, the utility model provides a kind of motorcycle engine suction tude that can play effect of heat insulation and grow working life.
For realizing above-mentioned purpose; The utility model provides a kind of motorcycle engine suction tude; Comprise the suction tude body, an end of suction tude body is provided with the adpting flange that is connected with engine cylinder head, is equipped with the aluminium inserts in the described adpting flange; The aluminium inserts is provided with thermal insulating pad outward, and aluminium inserts, thermal insulating pad and adpting flange fix through bolt.
The beneficial effect of the utility model is: adopt said structure; Owing to outside described aluminium inserts, set up thermal insulating pad, thermal insulating pad is contacted with engine cylinder head, avoid the aluminium inserts directly to contact with engine cylinder head; Thermal insulating pad can isolate out the most of heat on the engine cylinder head; Be delivered to heat on the aluminium inserts with considerably less, thereby make that the rubber part of suction tude is unlikely to that Yin Wendu is too high and aging, hardening or follow the string, prolong its working life.
The utility model can further be set to be equipped with seal ring between described aluminium inserts and the thermal insulating pad, is equipped with seal ring on the exterior edge face that joins with engine cylinder head on the thermal insulating pad.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1ly provided a kind of motorcycle engine suction tude; Comprise suction tude body 1; One end of suction tude body 1 is provided with the adpting flange 11 that is connected with engine cylinder head; Be equipped with aluminium inserts 2 in the described adpting flange 11, be provided with thermal insulating pad 3 outside the aluminium inserts 2, aluminium inserts 2, thermal insulating pad 3 and adpting flange 11 fix through bolt 4.Be equipped with seal ring 5 between described aluminium inserts 2 and the thermal insulating pad 3, be equipped with seal ring 5 on the exterior edge face that joins with engine cylinder head on the thermal insulating pad 3.
Adopt said structure; Owing to outside described aluminium inserts 2, set up thermal insulating pad 3, thermal insulating pad 3 is contacted with engine cylinder head, avoid aluminium inserts 2 directly to contact with engine cylinder head; Thermal insulating pad 3 can isolate out the most of heat on the engine cylinder head; Be delivered to heat on the aluminium inserts 2 with considerably less, thereby make that the rubber part of suction tude 1 is unlikely to that Yin Wendu is too high and aging, hardening or follow the string, prolong its working life.
Claims (2)
1. motorcycle engine suction tude; Comprise the suction tude body; One end of suction tude body is provided with the adpting flange that is connected with engine cylinder head; It is characterized in that: be equipped with the aluminium inserts in the described adpting flange, the aluminium inserts is provided with thermal insulating pad outward, and aluminium inserts, thermal insulating pad and adpting flange fix through bolt.
