Definitions
- the invention relates to a bicycle hub according to the preamble of claim 1 and a method for their preparation.
- Bicycle hubs in particular those having an internal toothing for a coaster brake with freewheel and an internal toothing as a correspondence hub gear, are previously forged from a pipe and finished machined by machining, including in addition to the introduction of the internal gears and a drilling holes of the molded rings counts to be hung in the spokes.
- the end-side, inner ball raceways are also made by machining, concretely by turning.
- Bicycle hubs are extremely expensive in relation to the remaining parts of a bicycle.
- these forged bicycle hubs are relatively heavy, since they must have a correspondingly thick wall as a condition for the shaping of both the forging as well as the machining.
- this relatively high weight is contrary to requirements, according to which the components should be designed in principle weight-optimized in the sense of weight-reduced.
- the two hub parts are positively or materially connected to each other, wherein as positive engagement a pressing or riveting is proposed, while the material bond is to be achieved by gluing or welding.
- a deformation is required, which can affect the concentricity of the bicycle hub.
- the welding leads to a delay of the hub parts, which can only be eliminated by appropriate straightening.
- the known construction leads to different diameters of the ball raceways, resulting in disadvantages in use.
- a desired weight optimization of the bicycle hub is limited by the loads occurring in the region of the ball raceways when driving, which require a corresponding wall thickness of the hub parts, which are essentially continuous in the known bicycle hubs, that is, the wall thickness is measured exclusively on the mentioned load.
- Another disadvantage of the known bicycle hub is to be considered that the two wheel rims, based on their distance from the respectively associated end face of the bicycle hub are different, so that an end portion of the bicycle hub projects outwardly beyond the connected spokes. Mainly by welding or soldering are the two wreaths on the
- the invention has for its object to further develop a bicycle hub of the generic type so that with improved load capacity, the sheet used can have a smaller wall thickness and a simplified and less expensive Hersannon is possible.
- This object is achieved by a bicycle hub with the features of claim 1 and a method for their preparation.
- the bicycle hub is produced in one piece by deep-drawing and forming a metal blank, in particular a closed blank, wherein after deep-drawing to a pot the bottom is separated and the end regions are shaped accordingly.
- the one-piece design of the bicycle hub enables extremely cost-effective production since, on the one hand, virtually all operations are possible in an uninterrupted, continuous mechanical process and, on the other hand, the use of materials is optimized.
- end regions one at a time and to connect them to one another by means of the sleeve, which is then designed as a separate part, or one of the end regions is integrally formed on the sleeve, so that both parts are in one piece.
- the other end portion as a separate hub part is fitted on the side opposite the molded end portion side on the sleeve.
- connection of the end region or regions with the sleeve takes place frictionally, for which purpose the diameters corresponding to one another in the sense of a
- end regions or an end region with a connected sleeve are produced from a blank, which is preferably in closed form, so that with According to the invention, the molding of the respective ring takes place by slipping the end region and then bending radially outward shaped into a ball track.
- the inventive method can be carried out in an automatic workflow, with corresponding forming machines are connected in succession, while the respective semi-finished product, from which ultimately the bicycle hub is completed, can be fed by automatic feeders.
- This automatic workflow leads to an extremely low-cost production of bicycle hub, since among other things, the production time is much shorter than that of a bicycle hub according to the prior art.
- To minimize costs also contributes to the relatively low cost of materials, which results mainly from the relatively thin wall thickness of the sheet used, which experiences sufficient stability by the doubling of the wall in the ball raceways.
- it is provided to guide the doubling into a covering area with brake shoes which are part of a coaster brake and which, in operation, that is to say during braking, are connected to the brake shoes. nenwandung the sleeve are pressed. The occurring radial forces are absorbed by the double wall, so that a deformation of the bicycle hub in this area is practically impossible.
- the low weight of the new bicycle hub has an effect on the total weight of the bicycle into which such bicycle hubs are installed, the bicycle hubs according to the invention, modified accordingly, being used for both the rear and the front wheels.
- FIG. 1 shows an embodiment of a bicycle hub in a longitudinal section
- Figures 2 and 3 are each a plan view of the bicycle hub Figure 4 is a detail of the bicycle hub of Figure 1 in a longitudinal section
- FIG. 5 shows another detail of the bicycle hub, also in one
- Figure 6 shows another embodiment of a bicycle hub in one
- FIG 7 shows another embodiment of a bicycle hub, also in a longitudinal section.
- a bicycle hub is shown in each case, which consists of two frictionally interconnected hub parts 1, 2, each having on the opposite sides an end portion 3, 4, in which end lying inside Kugelaufbahnen 8 are formed for receiving rolling balls.
- Each end region 3, 4 is formed in the region of the ball track 8 as a double wall, on the outer wall of which a ring 6, 7 connects, with holes 11 for receiving spokes.
- the double wall extends beyond, at least to a region 12 which is defined by a system of brake shoes, not shown, of a positioned inside the bicycle hub coaster brake.
- the rings 6, 7 are held apart by a sleeve 5 to each other, which is formed in the embodiments of the one end portion 3.
- the bicycle hub is manufactured by the following process steps:
- two parallel and spaced apart circumferential internal gears 9, 10 are provided for a hub circuit, one of which is functionally associated with a resignation with freewheel.
- the internal gears 9, 10 are made as well as the other deformations by cold forming, wherein the teeth of the internal gears 9, 10 are pressed from the outside. In the example shown in FIG. 1, both internal toothings 9, 10 are introduced into the first hub part 1.
- the ball track 8 of the second hub part 2 is produced by drawing in the inner wall of the double wall formed in this area, the outer wall of which is preferably frictionally engaged with the sleeve 5.
- the free end of the Kugeilaufbahn 8 is supported on the front side of the sleeve 5 from.
- the first hub part 1 can be seen as a detail, corresponding to the exemplary embodiment according to FIG. 1. It can be seen that the ring 6 is guided by slipping the hub part 1 produced by deep drawing and radially outward from the end side towards the outside extends.
- the second hub part 2 is shown in detail, which is pressed onto the cylindrical sleeve 5 of the first hub part 1 until the free end face of the ball track 8 comes to rest on the end face of the sleeve 5.
- FIG. 1 Another embodiment of the new bicycle hub is shown in FIG.
- the first hub part 1 has only one internal toothing 9, while the other internal toothing 10 is formed in the second hub part 2.
- the inner wall of the second hub part 2 forms an inner wall in the covering area with the first hub part 1, while the first hub part 2 bears against the rim 7 on the front side, thus representing a stop when the first 1 is pushed onto the second hub part 2. Both walls form a part of the sleeve 5.
- the two-part design of the embodiments shown offers the possibility of the second brake hub receiving the second hub part 2 consistently, so assembled form, while the hub gear on taking first hub part 1, depending on the design of the hub gear according to a modified number of gears execute, ie to vary in diameter. Only the overlapping region of the first hub part 1 required for frictional engagement is adapted thereto in each variant embodiment.
- a bicycle hub is shown, which is integrally formed from a round blank.
- the right end portion 3 is formed with its rim 6 corresponding to that shown in Figures 1 and 6.
- the ring 7 is made by folding, so that it is double-layered, while the double wall of the end portion 4 is made by drawing and achsparailele return of the sleeve 5, wherein the double wall of the end portion 4 covers the rim 7.
- the internal gears 9,10 are spaced from each other in the sleeve 5 introduced.
