Abstract
The invention discloses a novel double-vertical-pipe frame structure which comprises a head pipe, a lower pipe, an upper pipe, a vertical fork, a flat fork and a rear fork sheet. The novel double-vertical-pipe frame structure is characterized by further comprising a six-way middle joint connecting the lower pipe with the flat fork and a vertical pipe arranged between the upper pipe and the lower pipe, wherein the vertical pipe is composed of a double-vertical-pipe body and a single-vertical-pipe body. A double-vertical-pipe structure is designed so that the offset, generated after the size of the middle joint is increased, of the distance between a chain center of the single-vertical-pipe body and a center datum plane of a frame can return to the position of a common middle joint, so that the use requirement of a common chain shifting device is met, the strength of the frame is improved, and meanwhile the production cost is reduced.
Description
Technical field
The present invention relates to cycle frame technical field, more particularly to a kind of novel pair of standpipe body frame structure for automotive.
Background technology
The bicycle invention history of existing more than 200 year so far, does not consume the energy, easy to use due to it, therefore, is no matter in the flourishing American-European countries of industry, or developing country, welcomed by the people all the time.
At present, the body frame structure for automotive of bicycle has rhombus, U-shaped etc., but the whatsoever vehicle frame of form, as long as there being the support just be unableing to do without seat tube of front derailleur, and the position of seat tube, the length of center tap, Vee formation open a grade width, for the bicycle with front and back derailleur, when the length dimension of center tap changes bigger, what common front chain mover cannot meet bicycle installs and uses requirement, thus causing the forfeiture of its function. Therefore, parallel unanimously with vehicle frame center reference face in order to reach chain centrage, after open grade larger time, the size of center tap necessarily also to increase therewith, but the front chain mover of design is essentially all the size design according to center tap 68-73mm at present, such design virtually limits bicycle and uses the limitation of derailleur, that is, when the larger of center tap, the brachium of common derailleur is substantially not enough, brachium will be strengthened in order to use, increase production cost, reduce intensity and the safety of vehicle frame.
Therefore, how to be provided that a kind of be possible not only to fully meet common derailleur install and use requirement, frame strength can be improved again, the standpipe body frame structure for automotive reducing production cost is the problem that those skilled in the art need solution badly.
Summary of the invention
In view of this, the invention provides a kind of novel pair of standpipe body frame structure for automotive, what be possible not only to meet common derailleur installs and uses requirement, can improve again frame strength, reduce production cost.
To achieve these goals, the present invention provides following technical scheme:
A kind of novel pair of standpipe body frame structure for automotive, including: head tube; Lower pipe; Upper pipe; Seat stays; Chain stay; Dropout; Also include: connect the clematis stem center tap of described lower pipe and described chain stay; It is arranged at the standpipe between described upper pipe and described lower pipe; Wherein, described standpipe is made up of double; two standpipes and single standpipe two parts.
Preferably, in novel pair of standpipe body frame structure for automotive of above-mentioned one, described pair of standpipe is the standpipe composition that two dimensions are identical.
Preferably, in novel pair of standpipe body frame structure for automotive of above-mentioned one, one end of described pair of standpipe is first curved the process of deformation to vehicle frame central datum line direction, then according to the outside dimension of described single standpipe, described pair of standpipe being carried out milling arc or arc making, the mode finally by welding connects described single standpipe.
Preferably, in novel pair of standpipe body frame structure for automotive of above-mentioned one, described pair of standpipe is symmetrically distributed in the both sides of described center tap central datum line, and it is vertically connected on described center tap, described pair of standpipe can according to the installation dimension requirement of common derailleur simultaneously, adjust the relative position on described center tap so that it is reach the use scope of common derailleur.
Known via above-mentioned technical scheme, compared with prior art, present disclosure provides a kind of novel pair of standpipe body frame structure for automotive, change traditional independent standpipe body frame structure for automotive, but double; two standpipe mounting means that employing double joint is arranged side by side, not only the intensity of vehicle frame adds; The more important thing is, when the dimensions of center tap increases, owing to the brachium of common derailleur is inadequate, limit the use of derailleur, but double; two vertical tube structures of the present invention can be configured according to the installation requirement of common derailleur, therefore solve the trailing wheel of large scale center tap and width super large to open shelves and can not use the problem of common derailleur, but also reduce production cost, improve frame strength.
