Abstract
The utility model provides an integral bicycle front fork vertical tube, belonging to the technical field of bicycle. The integral bicycle front fork vertical tube comprises a tubular main body formed by forging, the tubular main body has a front section with a large wall thickness and a back section with a small wall thickness, and a bearing seat is arranged at the outer side of the front section. The integral bicycle front fork vertical tube provided by the utility model is integrally formed by forging, has simple structure, high strength and good safety, and is convenient and rapid in manufacturing.
Description
Technical field
The utility model relates to the bicycle front fork standpipe, especially a kind of integral bike vertical tube of front fork.
Background technology
Referring to Fig. 2, a kind of existing bicycle front fork standpipe comprises a vertical tube 10 ' and is enclosed within the one of which end and with it by the sleeve pipe 20 ' of weld part 30 ' adapter shaft bearing.Bearing seat sleeve pipe 20 ' is gone up the welding front fork tube, and wheel then is installed on the front fork tube, and the other end of vertical tube 10 ' supplies to install on the vehicle frame head pipe.Because of sleeve pipe will with the vertical tube pressing after in bottom welding, so fitting process is complicated, and welding is also normal, and welding to occur not firm, accident occurs so that in the process of riding, come off.On the other hand, its complicated structure has also increased manufacturing cost and material cost, has raised its price, has reduced the market competitiveness of bicycle maker.
The utility model content
The purpose of the utility model is to address the above problem, and a kind of integral bike vertical tube of front fork simple in structure and firm is provided.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is following:
A kind of integral bike vertical tube of front fork comprises the tubular body of forging molding having bigger leading portion of wall thickness and the less back segment of wall thickness, and the leading portion outside is provided with bearing seat.
Said leading portion begins wall thickness from the end and reduces gradually.
The beneficial effect of the utility model: the integral type forging molding, simple in structure, easily manufactured quick, intensity is high, and safety is good.
Description of drawings
Fig. 1 is the cutaway view according to the integral bike vertical tube of front fork of a kind of preferred embodiment of the utility model.
Fig. 2 is the cutaway view of the bicycle front fork standpipe of prior art.
The specific embodiment
Further specify below in conjunction with the specific embodiment of accompanying drawing the utility model:
Referring to Fig. 1, a kind of integral bike vertical tube of front fork comprises the tubular body 10 of forging molding.Tubular body 10 has wall thickness bigger leading portion 11 and the less back segment 12 of wall thickness.Leading portion 11 wall thickness reduce gradually, to adapt to the requirement of strength of connection location.Bearing seat 13 is located at leading portion 11 outsides, forges one-body molded with tubular body.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, make concrete change or change the protection domain that all belongs to the utility model.
