Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be described in further detail.
See Fig. 1, Fig. 4-6, a kind of gooseneck type aluminium alloy bicycle frame longeron, comprises by the upper plugging plate 1 of aluminium alloy extrusions shear forming, lower plugging plate 2 and girder 4; Namely upper plugging plate 1, lower plugging plate 2 and girder 4 are aluminium alloy extrusions and are formed by cutting processing.Described girder 4 is main body bearing parts of this longeron, and girder 4 adopts aluminum alloy extrusion section bar to be formed by cutting processing, and the cross sectional shape of this aluminum alloy extrusion section bar is " king " font, and its waste material cut down can melt down utilization again.Girder 4 comprises upper flange 7, epiplastron 8, substrate 9, bottom web 10 and lower wing plate 11, and described epiplastron 8 and bottom web 10 are vertical plate, epiplastron 8 and the respective two sides of bottom web 10 parallel to each other; Described upper flange 7, substrate 9 and lower wing plate 11 is horizontal plate, and the respective upper and lower surface of upper flange 7, substrate 9 and lower wing plate 11 is parallel to each other.Described substrate 9 is main bodys of girder 4, described upper flange 7 and epiplastron 8 are distributed in the front end of girder 4 upper surface, namely epiplastron 8 is arranged on the upper surface of substrate 9 front end, and epiplastron 8 vertical distribution is on the line of centers of substrate 9, upper flange 7 vertical distribution is above epiplastron 8, described bottom web 10 and lower wing plate 11 are distributed in the middle rear end of girder 4 lower surface, namely bottom web 10 to be arranged in substrate 9 on the lower surface of rear end, and bottom web 10 vertical distribution is on the line of centers of substrate 9, lower wing plate 11 vertical distribution is below bottom web 10; This kind of structure makes the longitudinal plane of symmetry of bottom web 10 overlap with the longitudinal plane of symmetry of epiplastron 8, and the longitudinal plane of symmetry of the longitudinal plane of symmetry of upper flange 7, the longitudinal plane of symmetry of substrate 9 and lower wing plate 11 is parallel to each other.Longitudinal plane of symmetry and the longitudinal plane of symmetry of epiplastron 8 of bottom web 10 refer to parallel with epiplastron 8 two sides with bottom web 10 respectively and to the equal plane of two lateral distance herein, for epiplastron 8 and bottom web 10, its thickness can be different, but their longitudinal plane of symmetry overlaps; The longitudinal plane of symmetry of the longitudinal plane of symmetry of upper flange 7, the longitudinal plane of symmetry of substrate 9 and lower wing plate 11 refers to the parallel faces between the upper and lower surface of same plate herein, and this face is identical to the distance of same plate upper and lower surface.Described upper plugging plate 1 is arranged on epiplastron 8 and upper flange 7 rear end, and upper plugging plate 1 and epiplastron 8, to connect by being weldingly connected between upper flange 7 and substrate 9, described lower plugging plate 2 is arranged on bottom web 10 and lower wing plate 11 front end, and lower plugging plate 2 and bottom web 10, to connect by being weldingly connected between lower wing plate 11 and substrate 9, the intermediate location formed by upper plugging plate 1 and lower plugging plate 2 forms the gooseneck place of this longeron; The weld seam 3 that this kind of structure makes upper plugging plate 1 and lower plugging plate 2 and girder 4 weld mutually is distributed in the side edge of this longeron, makes this longitudinal beam welding position few, does not have influence on the main body of longeron, good rigidly.
See Fig. 5-6, generally speaking, the longeron that superimposed trailer is applied has a front and back transitional region, needs to carry out gradual transition to an oblique angle, concentrates to avoid stress; For aluminum alloy longeron angle of bevel cross conference cause stress concentrate, easily rupture, angle of bevel angle too small can cause bank slope on longeron excessive, be unfavorable for lade.Therefore, preferably, described upper flange 7 and epiplastron 8 aft end face are respectively arranged with trimming 5, form an oblique angle between described upper trimming 5 and the upper surface of substrate 9, and the angle of bevel between upper trimming 5 and the upper surface of substrate 9 is between 25 ° ~ 60 °; Described bottom web 10 and lower wing plate 11 front end face are respectively arranged with lower trimming 6, and between described lower trimming 6 and the lower surface of substrate 9, shape in an angle, and the angle angle between lower trimming 6 and the lower surface of substrate 9 is between 25 ° ~ 60 °.
See Fig. 2-3, described upper plugging plate 1 and lower plugging plate 2 adopt cross section to be that the aluminium alloy extrusions of U-shaped processes, and expect that thick is 6mm; Upper plugging plate 1 and lower plugging plate 2 lateral profile are respectively parallelogram.
See Fig. 4-5, the size of described substrate 9, epiplastron 8, upper flange 7, bottom web 10 and lower wing plate 11 is selected according to actual needs, in the present embodiment, substrate 9 thickness is 18mm, width is 120mm, epiplastron 8 is highly for 120mm, thickness are 20mm, upper flange 7 thickness is 20mm, width is 120mm, bottom web 10 is highly 200mm, thickness is 16mm, and lower wing plate 11 width is 120mm, thickness is 16mm.
The form that the utility model longeron carries out cutting processing and repair welding by employing aluminium alloy extrusions is made, the welding just auxiliary connection in local, good rigidly; And the version of upper lower leaf is convenient to thicken the structure of front end, gooseneck place, structural strength is high, is easy to apply.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, said structure all should be considered as belonging to protection domain of the present utility model.
