Abstract
The utility model relates to a shaft linked flywheel-disc brake hub. One end of a middle pipe is provided with a convex reducing bushing in a press fit way; a ball bowl is arranged in the convex reducing bushing which is provided with hub vanes in an interference fit way; the extended end of the middle pipe is provided with a flywheel in a thread fit way. The shaft linked flywheel-disc brake hub has the advantages of scientific design, reasonable structure of the convex reducing bushing, increased cooperation intensity, symmetrical and coordinate hub vanes arranged at both ends of the middle pipe and increased whole assembly intensity. Because the structure of the shaft linked flywheel-disc brake hub is simplified, fixture can be reduced in the process of installation and the assembly and operating procedure can be simplified, which is favorable for specialized production.
Description
The utility model relates to the bicycle assembly parts structural development, especially a kind of conjuncted flywheel-type flower hub (be called for short: shaft coupling flies) that both can be used for, also can with the supporting dual purpose hub of disc brake.
Traditional shaft coupling flyings hub and common colored hub structure differ greatly, and parts can not exchange; And dish brake hub is the product that occurs in recent years, and different separately on design and the structure, parts must be made specially.The hub of two kinds of different structures can not exchange.Therefore maker then must be equipped with and the corresponding hub of model if will produce the bicycle of above two kinds of different models.Undoubtedly, this can make bicycle maker increase difficulty on the tank farm stock of spare part and the product transformation.
The purpose of this utility model is the defective that exists on the above-mentioned hub structure, and a kind of ordinary bicycle that both can be used for is provided, and also is applicable to the shaft coupling flywheel-disc brake dual purpose hub of the supporting installation of disc brake bicycle.
Shaft coupling flywheel-disc brake dual purpose hub of the present utility model, comprise: middle pipe, flower hub blade and pearl bowl, it is characterized in that: an end of middle pipe is equipped with a convex reducing bushing with press-fit, be provided with the pearl bowl in the convex reducing bushing, the colored hub blade that interference fit is installed on the convex reducing bushing; The interference fit of holding in addition of middle pipe is installed flower hub blade, and the external part of middle pipe is a threaded line pipe, and the external part of middle pipe is installed flywheel by cooperating with screw collar, and it is bowl-shape that an end of screw collar is designed to pearl.
Shaft coupling flywheel-disc brake dual purpose hub of the present utility model in the convex reducing bushing, had both reduced number of components with the design of pearl bowl, had also simplified installation exercise; If the external part of pipe in the hub is installed and fixed seat with thread fiting mode, and on permanent seat, video disc is installed, promptly become the dish brake hub tube.This dual purpose hub design science, the convex reducing bushing is rational in infrastructure, can increase cooperation intensity, and can make be installed in the pipe two ends colored hub blade symmetry, more become to coordinate, thereby the whole intensity of assembling is improved.Because the designs simplification of this dual-purpose hub has reduced frock clamp in installation process, simplified the assembly operation program, more help specialized production.
The concrete structure of the utility model shaft coupling flywheel-disc brake dual purpose hub by the following drawings and
Embodiment provides in detail.
Fig. 1 is the structural representation of shaft coupling flywheel-disc brake dual purpose hub;
Fig. 2 is that shaft coupling flywheel-disc brake dual purpose hub shown in Figure 1 is used scheme drawing.
Embodiment: can be clear that from Fig. 1 the lining 3 that crosses of shaft coupling flywheel-disc brake dual purpose hub is made of the tubule mouth 12 and the big mouth of pipe 13; Manage on 4 during tubule mouth 12 interference fit of convex reducing bushing 3 are installed in; Be provided with pearl bowl 2 in the convex reducing bushing 3 big mouths of pipe 13, the convex reducing bushing 3 big mouth of pipe 13 outer ring interference fit are installed flower hub lobus sinister sheet 1.The interference fit of holding in addition of middle pipe 4 is installed flower hub lobus dexter sheet 5, the external part 6 of middle pipe 4 is provided with screw thread, flywheel 7 inner rings are provided with one can be provided with the screw collar 8 that screw thread fit is installed with the external part 6 of middle pipe 4, one end of screw collar 8 is designed to pearl bowl 9 shapes, flywheel 7 external part 6 screw threads by screw collar 8 and middle pipe 4 cooperate installation.For pearl bowl 2 is in place, pearl bowl 2 is provided with flanged outer ring 10, and the flanged outer ring 10 of pearl bowl 2 is clamped between convex reducing bushing 3 and the flower hub lobus sinister sheet 1, can make pearl bowl 2 location more accurate.Convex reducing bushing 3 is made of the little mouth of pipe and the big mouth of pipe, is further simplified structure, and the transition groove 14 with tubule mouth 12 in the big mouth of pipe 13 of convex reducing bushing 3 is designed to the bowl-shape function with alternative independent pearl bowl 2 of pearl.
Assembling example when being shaft coupling flywheel-disc brake dual purpose hub shown in Figure 2 as dish brake hub, the left end car tooth of this dual purpose hub, and load onto flywheel and use as right-hand member, and the screw thread position that middle pipe stretches out is screwed on permanent seat, load onto video disc, promptly become dish brake hub.
