Description of the invention () Background of the invention The present invention relates to the design and construction of a bicycle fork suspension system. More specifically, the present invention relates to the use of the sole main compression spring system in a bicycle suspension fork. Bicycle forks for combining the front or rear wheels of a bicycle with a bicycle frame are well known. In addition, bicycle forks that include suspension systems to cushion riders from bumps and tremors when they come into contact with bumps, ruts, rocks, potholes, and other obstacles are also well known. Interference on the road is absorbed by the suspension system, and their harmful impact on the wheel and its rider is reduced or completely eliminated. One of the results of this reduction in shock is that the rider can better control the bicycle. In addition, the bicycle suspension system also serves the purpose of maintaining the contact of the bicycle wheel with the ground, thereby further improving the rider's control and control of the bicycle. Bicycle suspension front forks typically have a pair of front fork legs across the pedal wheels, each foot containing a pair of inner and outer telescopic front fork tubes. The inner fork tube is usually a tubular element and the outer fork tube is usually a lower tube element. However, the opposite configuration is also available. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. —I n ni Γ— n-/,-1 —-Order (Please read the precautions on the back before filling this page) The main compression spring assembly is typically set at The front fork feet are both, but in a pair of telescopic front fork tubes, the "compression spring assembly" biases the front fork tubes to an isolated state when the suspension system is in a middle (ie, no external load) state. The front fork tube is adapted to slide relative to each other when the frame is impacted, and the coil spring assembly therein resists the contraction force. When the front tube is shrunk together (the inner tube slides into the outer tube), if the impact force is applied by the spring assembly, the paper size applies to the Chinese National Standard (CNS) A4 (210 X 297 mm) A7 _B7____________ 5. Description of the invention () The compression force of the fork tube. The spring assembly is a part, if not all, of the energy given to this system during compression, depending on the type of spring used, and releases this energy to return the fork tubes to their neutral position. The front fork. When the tube is extended (the inner tube slides out of the outer tube), after the compression stroke, it will extend the stroke (or return stroke). The main spring assembly typically contains a helical coil spring, a flexible body member, an air spring, an actuated coil spring disk, or other similar spring or spring combination. Representatives of the main spring assemblies known here are shown in U.S. Patent No. 2,708,112 issued to Seddon et al.

In addition to the main compression spring assembly, the user ' s stopped and raised H spring to cushion the sharp impact between the moving parts of the suspension assembly when the inner and outer fork tubes are compressed to their maximum distance.

Only in one fork leg The use of the main compression spring assembly instead of the main compression spring assembly in each fork leg will help reduce the cost and weight of the bicycle. As far as the competitiveness of the bicycle and front fork manufacturing industry is concerned, the cost is reduced. It is more and more important. The reduction in weight is important for all bicycles and may be a key factor. Therefore, there is a need for a bicycle front fork that uses only one main compression coil spring assembly. A significant disadvantage associated with using a single main compression spring assembly for one foot of a front fork is that the front forks become more asymmetrically loaded when the main spring assembly is compressed and the inner fork tubes approach the lower part of their movement. Load is disadvantageous because it can cause unacceptably high stresses to be transmitted to the fork legs, the fork stays (the arches connecting the forks), and / or other fork constructions. Under such a load, the front fork structure needs to be reinforced, resulting in an increase in weight and an increase in the production cost of the bicycle, offsetting the cost and weight reduction achieved by eliminating the second main compression coil spring assembly. Therefore,-. 1 1-I 1 1-—-I.

Description of the invention () There is a bicycle front fork with a single main compression spring system that reduces the asymmetric load generated by using only a single main compression spring assembly need. SUMMARY OF THE INVENTION The object of the present invention is to provide a bicycle suspension system having a main compression spring only in one of the front fork feet. However, the bicycle suspension is made in a shape that minimizes any asymmetric load that may be caused by using such a spring system. Front fork. This and other objects are in accordance with the principles of the present invention, by providing a suspension front fork having a single main compression coil spring system in only one front fork leg, and a method of assembling such a suspension front fork, The load can be more evenly distributed to reduce any asymmetric load that would otherwise be caused by using only a single main compression spring assembly on one side of the fork. In particular, the front fork feet that do not contain the main compression spring assembly , Or both sides of the fork fork are suitable for the load distribution assembly. Compared to any front fork leg, the load distribution assembly of the present invention is such that compression of the inner and outer telescopic tongues of the front fork leg will cause compression of the load distribution assembly. Unlike the main compression spring assembly, this load distribution assembly is not intended to bias the inner and outer fork tubes at all times to separate them or resist the compression force applied to the fork legs, although in some specific cases This load distribution assembly can provide some bias boost. Instead, the load distribution assembly becomes effective after the initial movement of the fork tube. However, unlike a typical stop-and-return spring (which is only effective at the end of the compression stroke), this load distribution assembly is effective before the near-stop-to-return state. In particular, this load distribution assembly is provided as a part of the movement of the fork tube toward the end of the compression stroke (please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 specifications (210X297 mm) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ____B7___ V. Description of the invention () Resistance to the compression force of the front fork foot. For example, this load distribution assembly may have a reed spring that fits between the bottom of the inner fork tube and the bottom of the outer fork tube, so that although the current fork tube is in an uncompressed state, it will provide some biasing force, providing Meaningful resistance to compression. However, preferably, this load distribution assembly provides such resistance in about the last third of the movement of the fork tube during the retracting stroke, because this part of the compression stroke is usually where the fork will be tested to its maximum. Where the load is. The load distribution assembly may include any type of air spring, helical spring, bow spring, or flexible spring, or any other type of spring or spring combination, as long as the spring or spring combination Will reduce the asymmetric compression force caused by the use of a single main compression reed spring system on one side of the suspension fork, which usually requires the reinforcement of the fork legs, stays, or other fork structures. In addition, those who are proficient will It will be noticed that this load distribution assembly can be fit between the bottom of the inner fork tube and the bottom of the outer fork tube, the top of the inner fork tube and the piston extending from the outer fork tube into the inner fork tube Between, in some other working positions, and can be arranged on the inner or outer side of the inner and / or outer fork tube. The above and other objects, features, and advantages of the present invention will be immediately apparent from the following detailed description together with the appendix.

Print A7 __B7_ V. Description of the invention () Spring 54 is the best It is a flexible body spring that can be made of microbubble urethane (" MCU ") as shown in Figure 1, because the main compression spring assembly 50 is best placed in the inner fork tube 20, that is, the front suspension In the upper tube of the front fork 10, the compressed meal spacer 56 is adapted to be placed between the top cover assembly 58 and the compressed leaf spring 54. As described in further detail below, the lower end of the compressed leaf spring 54 contains The piston assembly 60 of the piston shaft 62 at one end 64 and the second end 66 is supported and maintained in the inner fork tube 20. The end plate 68 is disposed on the first end 64 of the piston shaft 62 and is adapted to be wrapped around the second end 34 of the inner fork tube 20 to provide a seat for the compression spring 54. The first end 64 and the end plate 68 are The inner fork tube 20 slides inside and the second end 66 of the piston shaft 62 is coupled to the second end 42 of the outer fork tube 24 to allow compression of the front fork leg 16 and the reed spring 54. The flange 70 is provided on the second end 34 of the inner fork tube 20 (Fig. 1). Therefore, during the extension of the front fork feet 14, 16, the flange 70 will prevent the end plate 68 front fork 20 from being pulled out. Thus, the piston shaft 62 and the outer fork tube 24 interconnected with the end plate 68 are prevented from becoming separated from the inner fork tube 20. The peak spring 72 is preferably disposed on the first end 64 of the piston shaft 62 below the end plate 68. The apex spring 72 can be formed from any flexible material known in the art. As can be seen in FIG. 1, when the compression coil spring assembly 50 is fit in the front fork 16, the apex coil spring 72 is fit in the flange 70 of the end plate 68 and the inner fork tube 20. Therefore, during the rebound of the suspension system, the inner and outer fork tubes 20, 24 are close to their extension limits and the second end 34 of the inner fork tube 20 is close to the first end of the outer fork tube 24 At 38 o'clock, reaching the apex spring 72 cushions the -9 between the end plate 68 and the flange 70.

Finally, the piston shaft 62 extends through the axial cavity in the reaching vertex spring 72 so that the reaching vertex pinch spring 72 will fit around the piston shaft 62. It is shown in Figures 1-3 In the silly specific example, the main compression spring system 12 is also included. As shown in FIG. 1, it is preferable that the load distribution system 52 is located in the front fork foot 14 without the main compression spring assembly 50. However, necessary The hour load distribution system 52 may be located on both the front fork feet 14, 16. As best seen in Figure 3, the load distribution system 52 includes a load distribution spring 80, a load distribution spring spacer 82, and Piston shaft 62. Best of all, the load distribution spring 80 and the load distribution spring spacer 82 are ring-shaped so that the piston shaft 62 will pass through it. A ring-shaped rigid or semi-rigid plastic spacer that can withstand the compressive load that may be applied to the load distribution assembly 52. The load distribution spring 80 is preferably a ring-shaped elastic body spring, and particularly preferably microbubble urethane. There are two main advantages to using microbubble urethane as a load distribution spring. First, microbubble urethane has the ability to make the elastomer non-linearly for each incremental unit of the compression distance of the spring. The increased load increase is distributed over the increasing spring stiffness of the fork leg without the main compression spring assembly. Second, as expected, microbubble urethane is lighter and more suitable than many alternative spring constructions. Nevertheless, but The materials used to form the load-distributed reed spring 80 and the load-distributed reed spacer 82 are selected according to the load distribution characteristics required by the system. Therefore, materials that are not listed here can be included as long as they can achieve The load distribution ball is ok. 4 For those who are proficient in this way, it will be obvious when the load distribution bomb -10- This paper size applies the Chinese National Standard (CNS) Α4 specification (210X297 mm)!

As soon as the compression, the load distribution spring 80 will distribute a contraction load to The front fork leg with the main compression spring assembly reduces the load that would otherwise be experienced by the front fork leg with the main compression spring assembly and reduces the need to reinforce the front fork structure to withstand asymmetric loads. The load distribution system 52 is preferably the last half of the movement (compression stroke of the front fork 10) of the inner fork tubes 8, 20 into the outer fork tubes 22, 24, and preferably the last three points The compression load is effectively distributed during one of the periods. However, this preferred range may change in other forks or alternative suspension assemblies, depending on the particular design of the fork or device being considered. Therefore, in general, it is best to shape the load distribution reed assembly and fit it to redistribute the asymmetric load in the range of motion that needs to be redistributed to avoid reinforcing the front fork or other structural components of the suspension assembly Need. It will be seen that the spacer 82 is adjustable or can be replaced with a spacer of a different size or shape. The position of the load distribution reed spring 80 is changed and the load distribution system 52 will effectively distribute compression or other loads during compression of the bicycle fork. point. The load distribution system 52 may be adapted in any manner to any surface that allows it to transfer the load from the inner fork tube to the outer fork tube. Therefore, although the first to the third digits show the load distribution spring 80 of the front fork leg 14 being secured to the load distribution spring spacer 82 disposed on the lower end 42 of the outer fork tube 22, it will be known Other configurations that would provide the same load distribution are within the scope of the principles of the invention. Although the foregoing descriptions and drawings represent a better specific example of the present invention, they will be explained. 11- This paper size uses the Chinese National Standard (CNS) 8 4 specifications (210X297 mm) (Please read the precautions on the back before filling out (This page) »-Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs.
