To achieve these goals, the invention provides following technical scheme:
A kind of novel list curved partial center standpipe body frame structure for automotive, comprises, head tube; Lower pipe; Upper pipe; Vertical fork; Chain stay; Dropout; Also comprise: the center tap connecting described lower pipe and described chain stay; Be arranged at the curved partial center standpipe of list between described lower pipe and described upper pipe; Be fastened on the reinforced sheet of described center tap and single curved partial center standpipe; Wherein, described list curved partial center standpipe is made up of uprise and the curved standpipe two parts of partial center.
Preferably, in the novel list of above-mentioned one curved partial center standpipe body frame structure for automotive, the process of one end advanced line bend distortion to vehicle frame central datum line direction of the curved standpipe of described partial center, then carry out milling arc or arc making according to the outside dimension of described uprise to the curved standpipe of described partial center, the mode finally by welding connects described uprise.
Preferably, in the novel list of above-mentioned one curved partial center standpipe body frame structure for automotive, described reinforced sheet is triangle, and is arranged on larger side, described partial center curved standpipe partial center position.
Preferably, in the novel list of above-mentioned one curved partial center standpipe body frame structure for automotive, the curved standpipe of described partial center is connected with described reinforced sheet the both sides being distributed in described center tap central datum line, and be vertically connected at described center tap, the curved standpipe of described partial center can according to the installation dimension requirement of common derailleur simultaneously, the relative position of adjustment on described center tap, makes it reach the range of use of common derailleur.
Known via above-mentioned technical scheme, compared with prior art, the utility model openly provides a kind of novel list curved partial center standpipe body frame structure for automotive, by adopting the curved partial center standpipe of list and the reinforced sheet of design uniqueness, make the chain line of centers of standpipe and the distance in vehicle frame center reference face, the side-play amount occurred after center tap incremental sizes revert on the position of common center tap, what so not only meet common derailleur installs and uses requirement, also improve frame strength, reduce productive costs.
