Abstract
The invention relates to a herringbone reinforced oblique beam bicycle frame, which comprises an oblique beam, a front fork sleeve, a middle shaft bushing and a saddle bushing, wherein the two ends of the oblique beam are fixedly provided with the middle shaft bushing and the front fork sleeve. The herringbone reinforced oblique beam bicycle frame is characterized in that a herringbone beam is fixedly arranged on the front fork sleeve in the same direction as the oblique beam; the herringbone beam and the oblique beam form an arch; the arched top end part of the herringbone beam is fixedly provided with a saddle supporting beam 3; and the end part of the other end of the saddle supporting beam is fixedly provided with the saddle bushing. According to the bicycle frame, the herringbone beam is fixedly arranged on the front fork sleeve and the oblique beam, and the herringbone beam and the oblique beam form an arch, so that the strength of the oblique beam can be effectively enhanced; and the arched top end part of the fixedly arranged herringbone beam is fixedly provided with the saddle supporting beam of which the end part is fixedly provided with the saddle bushing, and the saddle supporting beam is coaxially and fixedly provided with one to three reinforcing ribs, so that the structure of the entire frame is simplified, and meanwhile, the strength of the entire frame is also improved.
Description
Technical field
The invention belongs to the bicycle field, relate to vehicle frame, especially a kind of chevron pointing is strengthened the cant beam bicycle rack.
Background technology
At present; Cycle frame is the main load parts of bicycle, generally comprises the front fork sleeve that is used to install front fork, is used to install the saddle sleeve pipe of saddle; Be used to install the axis sleeve pipe of axis; Through put the beams in place connecting, connect through cant beam between axis sleeve pipe and the front fork sleeve between front fork sleeve and the saddle sleeve pipe, and be connected through founding beam between saddle sleeve pipe and the axis sleeve pipe; Also establish the rear axle crotch that is used to install trailing wheel in addition, the end that the rear axle crotch merges is used to install rear axle, and captive joint with axis sleeve pipe and saddle sleeve pipe respectively in two ends in addition.
In addition; Some bicycle rack utilizes horizontal " people " font support beam to replace upright beam and upper beam; Captive joint with front fork sleeve in " people " font support beam top; An end is captiveed joint with the saddle sleeve pipe in its two tail ends, and the other end is captiveed joint near the position of axis sleeve pipe with axis sleeve pipe or cant beam.
But adopting the problem of " people " font support beam is that its bifurcation is stressed more concentrated, is easy to generate fatigue, therefore must suitably strengthen.
Through understanding, do not find that as yet other can solution to the problems described above.
Through retrieval, do not find the publication document relevant as yet with application of the present invention.
Summary of the invention
The objective of the invention is to overcome the weak point of prior art, provide a kind of chevron pointing to strengthen the cant beam bicycle rack,, and simplify body frame structure for automotive with the bulk strength of raising bicycle rack, and create an aesthetic feeling.
The objective of the invention is to realize like this:
A kind of chevron pointing is strengthened the cant beam bicycle rack; Comprise cant beam, front fork sleeve, axis sleeve pipe and saddle sleeve pipe; The cant beam two ends install axis sleeve pipe and front fork sleeve, it is characterized in that: on front fork sleeve, install a lambdoid herringbone beam in the same way jointly with cant beam, this herringbone beam and cant beam form an arch; Install saddle support beam at herringbone beam's position, arch top, the end of the other end of this saddle support beam installs the saddle sleeve pipe.
And the coaxial 1-3 sheet that installs of saddle support beam lower edge between saddle sleeve pipe and herringbone beam is strengthened fin, on this reinforcement fin, is shaped on hollow hole.
And, strengthening also being shaped on the mounting hole that is used for the carry damping spring on the fin.
Advantage of the present invention and good effect are:
1, this bicycle rack installs a lambdoid herringbone beam with cant beam jointly on front fork sleeve, and this herringbone beam and cant beam form an arch, can effectively strengthen the intensity of cant beam.
2, this bicycle rack install at the herringbone beam's who is installed position, arch top one install the saddle sleeve pipe in its end saddle support beam; And the coaxial 1-3 sheet that installs is strengthened fin on saddle support beam; Not only simplify the structure of whole vehicle frame, also improved the intensity of unitized frame simultaneously.
3, this bicycle rack adopts the chrome-molybdenum steel material, and processability absorptive character good, that impact are good, than titanium, aluminium welding easily, can be designed to different shape; In addition, do not need heat treatment after the welding of the bicycle rack of chrome-molybdenum steel material yet, therefore do not need large-scale heat treating facility.
Description of drawings
Fig. 1 is the structural representation of bicycle rack of the present invention.
The specific embodiment
Through specific embodiment the present invention is made further detailed description below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of chevron pointing is strengthened the cant beam bicycle rack, referring to Fig. 1, comprises cant beam, front fork sleeve, axis sleeve pipe (first three parts is prior art, does not therefore have label) and saddle sleeve pipe 1, and the cant beam two ends install axis sleeve pipe and front fork sleeve.Innovative point of the present invention is:
1, on front fork sleeve, install a lambdoid herringbone beam 2 in the same way jointly with cant beam, this herringbone beam and cant beam form an arch.
2, install saddle support beam 3 at herringbone beam's position, arch top, the end of the other end of this saddle support beam installs the saddle sleeve pipe.
3, the coaxial 1-3 sheet that installs of the support of the saddle between saddle sleeve pipe and herringbone beam beam lower edge is strengthened fin 4, on this reinforcement fin, is shaped on hollow hole 5, with expendable weight, improves vehicle frame toughness simultaneously.
4, strengthening also being shaped on a mounting hole 6 on the fin, be used for carry damping spring or miscellaneous part.
The described mode that installs of present embodiment installs for welding.
This bicycle rack adopts the chrome-molybdenum steel material, and processability is good, and the absorptive character of impact are good, and utilization reinforcement fin improves herringbone beam's part and strengthens in addition, has improved the bulk strength of bicycle rack.
