Creation Instructions () Warehouse!] Background: This warehouse is an improved structure of a bicycle front fork, especially a type that does not require welding and binding. Improved bicycle fork structure that is connected, glued, or combined with rivets and styles. According to the press, the bicycle front fork is a very important knot in the bicycle frame. Its main function is to install the front wheel and provide the effect of front wheel steering. And it is the front of the new generation of high-mountain bikes. The fork has a structure of a shock absorber, so the structure of the bicycle fork is more complicated. Because the bicycle front fork must bear the heaviest weight of the bicycle and the rider when the bicycle is traveling, and it must withstand the movement of the front wheel when it is in contact with the uneven ground, the bicycle front fork must have good strength. 'Μ Prevents the danger of tipping the fork and overturning the bicycle. In addition, in order to maintain the stability of the bicycle's driving and steering movements, the bicycle front fork must have excellent size and angle accuracy so that the front wheel of the bicycle can be installed at the correct position and angle. The conventional bicycle front fork can be divided into: welding type, brazing type, and combination type according to its combination method. As shown in FIG. 6, it is a structure of a conventional welded bicycle fork, which mainly includes: a standpipe 1 which can be installed in a front cum cover of a bicycle frame by a ball disc device, and above the bicycle frame. Front handle connection; and a front fork shoulder 2 * attached to the bottom end of the cum tube 1; and two front fork feet 3 attached to the two ends of the front shoulder 2 and the bottom ends of the two front fork legs 3 It can be used to attach a bicycle wheel.

Creation Instructions () This type of welded bicycle fork is directly welded by oxygen welding or C0 2 welding. However, due to gas welding and C0 2 welding must be able to be completed by skilled workers, and because the welding is time-consuming, the production speed is slow, so the manufacturing cost is quite expensive. At the same time, due to the high heat generated during gas welding or C0 2 welding, the front fork will become flawed after welding. Therefore, the shape and angle of the bicycle fork must be further corrected. K maintains the accuracy of the size and shape angle. . As shown in Fig. 7, it is a structure of a bicycle front fork using a combination of brazing. It also has a vertical pipe 1A, a front fork shoulder 2A, and a front fork foot 3A. It is then manufactured by brazing, and after the two front fork legs 3A and the front shoulder 2A are fitted, it is also welded and assembled by M brazing, so the production process must also consume a lot of manpower. Once production takes time and effort. In addition, this type of brazed bicycle fork also has deformation problems after welding, so it is also necessary to further correct its size and shape. In addition, some bicycle front forks are fixed by glue or ruthenium ruthenium to secure the front fork shoulders to the bicycle front fork feet and standpipes. Among them, the adhesive bonding method must use special and expensive adhesives for bonding, and the adhesive is easy to fall off and lose its effectiveness for a long time. The rivet bonding method uses a rivet to roughly connect the front fork 束 and the beam tube. However, the bicycle fork that is fixed in combination with this method may shake the tube up and down. Therefore, the bicycle fork which is fixed by combining the two methods is not ideal. As shown in FIG. 3, it is a tight-type bicycle front fork structure. The front fork periphery 2B of the bicycle front fork is usually made of aluminum alloy. -3- JI'III!-II ^ · ί!.!

Because this kind of tight bicycle front fork must be provided with at least 6 screw holes on the shoulder of the fork, it must be drilled and tapped on the shoulder of the fork when it is being manufactured. * Makes it complex and time-consuming. At the same time, the assembly must use a lot of screws, so the assembly work is quite cumbersome and time consuming. Due to M reasons *, the production of conventional bicycle forks is labor-intensive and time-consuming, and its production cost is expensive. In addition, in addition to the disadvantages of difficult and expensive production of the various conventional bicycle front Xs mentioned above, the stern tube, front fork shoulder, and front fork foot are fixed and combined after the production is completed, and cannot be disassembled, so When manufacturers of bicycle front forks send the finished bicycle forks to a bicycle assembly factory for assembly, or when they are delivered to a sales location, they will be very deformed due to the collision.
