Description
Technical field
The utility model relates to a kind of suction tude of combustion engine, especially connects the suction tude between motorcycle engine and the Carburetor.
Background technique
The motorcycle engine suction tude of prior art, general with two kinds, a kind ofly be: by aluminium or the casting of other metal molten global formation, be cast as the pipe of a two ends band installation flange disc, one end flange disc is used for being connected with motor, and the other end flange disc is used for being connected with Carburetor.There is following defective in this suction tude: at first be not heat insulation, owing to make with metallic material, engine temperature is generally very high, and heat is directly delivered to Carburetor, influences its proper functioning; Next is not damping, and it almost is hard the connection with the very large motor of vibrations, suction tude self and Carburetor are damaged easily or influences its proper functioning; Secondly be that manufacture cost is higher again, because the suction tude shape need adapt to the shape and the spatial position of motor and Carburetor, therefore the two ends flange disc presents different shapes and space angle, and two flange disc end faces generally also need sealing in installation, although used O-ring seals when mounted, but the metal casting moulding does not often reach requirement in the uneven or spatial form position of attachment face, just needs end face of machining, brings manufacture cost higher; Be in addition install not too convenient, the suction tude both ends of the surface are connected with motor and Carburetor, general all is the method that adopts the hole of flange disc to wear screw or bolt, multi-processing tapped hole on the flange disc end face possibly so not only, increase during installation and twist the screw time, but also because of number of spare parts is many, screw nut is a lot of, installs cumbersome.
In order to overcome the defective of above-mentioned full-metallic suction tude, another kind of combined type suction tude has appearred on the market, the profile and the above-mentioned full-metallic suction tude of combination are basic identical, be equivalent to above-mentioned full-metallic suction tude from one section of pipe central cut-out, thereby be divided into two, outside two-part melt-forming that is divided into two wrapped with ebonite again, and a full rubber segments is just arranged in the middle of the pipe, at one end install two double threaded screws in advance in the tapped hole of face simultaneously, form the integral body of a band two screw rods.This suction tude has effectively overcome the defective of above-mentioned not heat insulation, not damping, the trouble when having alleviated the installation that causes because of number of spare parts more; But, because an original part has become three now, brought the manufacturing difficulty of itself again, such as, the part of two ends flange disc is because abnormity needs casting separately separately, both ends of the surface still need machining once, screw thread all still will be processed, also will be once with the rubber-moulding bag, and cost is higher, the inner tube wall of Xing Chenging also may be bad and rugged with combining of metal because of rubber at last, influences the air inlet quality.
Certainly, suction tude also has other forms, and as half encapsulate pipe, it is one section metal, be rubber or plastics in addition, the shortcoming of this method and to be combined into tracheae much the same.
The model utility content
Therefore, in order to overcome the shortcoming that above prior art exists, the utility model provides a kind of integrally-built motorcycle suction tude, reduces manufacture cost, reduces trouble is installed.
In order to achieve the above object, the motorcycle suction tude of technical solutions of the utility model, it comprises forward flange dish, rear stub, the body and the pipe hole that are connected with the front and back flange plate, wherein, is useful on attachment hole that is connected with motor and the seal groove that is used to seal on the forward flange dish; On described rear stub, be provided be used for being connected with Carburetor embed wherein double-screw bolt with fusion cast process, and the axis with body is that the center is provided with annular groove on flange plate and end face that Carburetor is connected, and the suitable sealing surface of seal element of size and Carburetor is arranged between the inner ring of this annular groove and the pipe hole; Described forward flange dish with end face that motor is connected on be positioned at that part is provided with technology groove outside the described seal groove.
As further improvement in the technical proposal, the boss that links to each other with body can be established in the back side of the end face that described forward flange dish is connected with motor around attachment hole, also can establish the boss that links to each other with body around the embedding double-screw bolt at the back side of the end face that described rear stub is connected with Carburetor.
The utility model has the advantages that: because: 1. embed wherein with the fusion cast process method by the double-screw bolt that will be used for being connected, reduced the number of spare parts when installing, also needn't reprocess tapped hole simultaneously with Carburetor; 2. the setting of the technology groove of forward and backward flange plate, annular groove and special-purpose sealing surface has guaranteed that the flatness of flange plate end face in manufacture process meets seal request, in addition machining; Therefore, can reduce manufacture cost, reduce trouble is installed.In addition, boss is set around hole that is connected with suction tude or the double-screw bolt, guaranteed the requirement of strength of connection part, and make when stressed transition of stress steady, lower but the more resilient material of suitable material intensity, for example engineering plastics are made product of the present utility model, just can play heat insulation and effect damping.
