Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a vibration isolation structure for a bicycle chassis.

[0002]

[Prior art]

 Most of the anti-vibration structure adopted by general bicycles waits for structural changes in the front and rear Y-tubes, and when the road surface is unflat, the front and rear Y-tubes are used. It absorbs the vibrations received by and has a proper cushioning effect.

[0003]

[Problems to be solved by the device]

 The structure and design as described above can certainly exert its effect, but on the other hand, the true goal of comfort and safety can be completely achieved only when the entire chassis itself has a vibration absorbing capacity. Do not consider. Therefore, although the front and rear Y-shaped pipes can be used to absorb the vibrations received by the wheels, the pressure exerted on the vehicle body by the heavy pressure carried by the person when the road surface is unflat is relatively timely. Before I knew it, I could not cancel it.

On the other hand, there is also an attempt to provide a vibration damping effect by installing a hydraulic cylinder capable of producing a stretched state. However, since the operation of the hydraulic cylinder is maintained in the state of being linearly contracted or stretched, when the chassis receives further vibration pressure, the pressure received can be loosened and reduced, and it can be eliminated at the appropriate time. The connection points at both ends of the hydraulic cylinder return to absorb the vibration force. For this reason, the vibration force is concentrated at the connection point, and there is the potential for considerable damage to the entire chassis and hydraulic cylinder, and it is also safe for the occupant. It can be said that it creates a very serious threat.

The present invention has been made to solve the above-mentioned drawbacks, and is capable of achieving vibration absorption quickly and effectively, and is easy and quick to assemble and disassemble, and has effects such as weight reduction and cost reduction. The purpose of the present invention is to provide an anti-vibration structure for a bicycle chassis.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a type of bicycle chassis vibration isolation structure. In this structure, a position limiting nut, a ring-shaped spring, a dustproof cover and a localization soft ring are provided on the connecting rod at the end of the upper front undercarriage rod of the undercarriage. It penetrates through the ring and the soft ring, and the fixing nut and the adjusting nut are screwed together and fixed on the connecting rod. In addition, the hollow joint pipe provided corresponding to the front connecting pedestal is fitted into the U-shaped joint pipe of the rear connecting pedestal, and the screw rod is the hollow joint pipe and the U-shaped joint pipe. It penetrates through the circular through holes on both sides and is further aligned with the nut for localization. In this way, the present proposal can achieve vibration absorption quickly and effectively, is simple and quick to assemble and disassemble, and has effects such as weight reduction and cost reduction.

The adjusting nut 9 is located between the fixed nut 8 and the C-shaped ring hook 9A, and corresponds to the movement of the fixed nut 8 and adjusts and controls the elasticity change of the ring-shaped spring 3.

Further, the C-shaped ring hook 9A is located in the ring-shaped groove 114 of the connecting rod 11, and after the connecting rod 11 penetrates the through hole 122 of the connecting pipe 121 of the base rod 12, it is subsequently fixed. It is localized. Further, the rear thread notch 113 of the connecting rod 11 penetrates through the through hole 122 of the connecting pipe 121 of the base rod 12, and further penetrates the hollow rear reinforcing plate 6 and the hollow ring-shaped soft ring 7, Further, the fixing nut 8 and the adjusting nut 9 are screw-connected to each other, and the C-shaped ring hook 9A is fixed in the glue ring-shaped groove 114 of the connecting rod 11 (see FIG. 3) so that it is provided on the front connecting base rod 13. Corresponding to the hollow joint pipe 131, it is fitted into the U-shaped joint pipe 141 of the rear connecting bar 14. Further, the threaded rod 1B penetrates the hollow joint pipe 131 and the circular through holes 142 on both sides of the U-shaped joint pipe 141, and is further connected to the nut 1C for localization (see FIG. 4).

When the road surface is unsupported, the vibration of a vibration actuated by using the above-described coupling of the rear connecting bar 14 of the front connecting bar 13 to the U-shaped joint pipe 141 of the joint pipe 131. In the situation, the position limiting nut 2 to which the front connecting rod 11 is connected, the ring-shaped spring 3, the dustproof cover 4, the localization soft ring 5, the front reinforcing plate 6, the connecting rod 11 pipe 121, the rear reinforcing plate 61. Then, the soft ring 7, the fixing nut 8 and the adjusting nut 9 are made to correspond to each other, and the expansion and contraction state is appropriately expressed as shown in FIG. In this way, the entire chassis 1A is completely released from the vibrating force that can be contacted and dispersed. As described above, the present invention has a quick vibration-proof effect, is easy and quick to assemble and disassemble, can be reduced in weight and cost, and can achieve effects such as safety and comfort.

Further, the pedestal 15 can be changed to a horizontal type in order to correspond to the undercarriage structure of each style car model. At the same time, a through hole 152 (a hole having a longer hole is preferable) is formed in the connecting pipe 151, and similarly, the position limiting nut 2, the ring-shaped spring 3, the antistatic cover 4, and the localization soft ring 5 are provided on the front connecting rod 11. Is installed, and the hollow convex end 52 of the localization soft ring 5 is installed on the hollow convex end pipe 6A1 of the localization convex ring 6A and coupled, and the hollow convex end pipe 6A1 is fitted to the ring-shaped spring 3 and localized. Prevents warping and slippage.
