Description

Bicycle front fork suspension structure improvement

This creation department is concerned with a suspension structure, especially an improvement of the bicycle front fork suspension structure.

According to a bicycle shock absorber, as shown in Figures 7, 8, and 9, the shock absorber 60 includes a sleeve 61, a piston 62, an elastic member 63, and a pivot mechanism 64. A sleeve 61 has a cavity 611, and a through hole 612 is formed at one end of the sleeve 61 to communicate with the cavity 611. A piston 62 is movably received in the cavity 611 of the sleeve 61. A piston rod 621 is disposed at one end of the piston 62, and an elastic member 63 is disposed in the cavity 611 of the sleeve 61. The two ends of the elastic member 63 are respectively elastically supported by the sleeve. Between the other end of the cylinder 61 and the other end of the piston 62, a pivoting mechanism 64 includes a rotating member 641 and a fixing member 642 rotatably connected to each other, and the fixing member 642 is fixed to the sleeve 61. At the other end, a front fork suspension structure is completed; when the combination of the structures is used, the shock absorber 60 is mounted between the first connecting portion 71 and the second connecting portion 72 of the front fork 70, when the front wheel of the bicycle is subjected to When the vibration from the ground occurs, the distance between the first and second connecting portions 71, 72 of the front fork 70 will be shortened accordingly, and the piston 6 2 is accordingly pushed in the sleeve 61 to elastically compress the elastic member 63 to achieve the shock absorbing effect, since the front fork 8 must withstand vibrations from various directions of the ground, at this time, the shock absorber 60 Can be pivoted by the addition The mechanism 64 automatically fine-tunes the various vibration directions from the ground to achieve a better cushioning and shock absorbing effect.

It is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reason is as follows: the rotating member 641 and the fixing member 642 which are connected to the pivoting mechanism 64 of the conventional shock absorber 60 are axially phased. The connection is made such that the fixing member 642 can only be adjusted in the radial direction of the rotating member 641 by the concentric circle, so that the pivoting mechanism 64 can only adjust the offset in the upper and lower symmetrical directions, resulting in vibration generated when the bicycle is turned left and right. It is impossible to achieve the buffering and shock absorbing effects through the pivoting mechanism 64, and the use efficiency of the shock absorber is greatly reduced, and the utility is lacking.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention is to provide an improvement of the bicycle front suspension structure in view of the above-mentioned shortcomings existing in the prior art.

The bicycle front fork suspension structure is improved, comprising: a hydraulic pipe, a upper seat, a universal seat and a connecting seat, wherein a hydraulic pipe has a compression chamber hollow and communicates through the upper and lower ends An upper opening and a lower perforation are provided. The compression chamber is sequentially inserted into an inner shaft and a cushion from the upper opening, and the inner shaft protrudes from the lower perforation and is closed by a cover closure. Moreover, the open end of the oil pressure pipe is expanded to have a fastening base, and the hydraulic pressure pipe sleeve has an elastic member, and a lock knot perforation is arranged at the center of the upper seat, and the lock is perforated and the inner shaft is locked and fixed. At the same time, it abuts against the elastic member, and the top end of the upper seat has a combined portion, the bottom portion of the universal seat forms a joint portion and the combined portion of the upper seat, and the upper end surface forms a convex arc with a spherical shape. And a sleeve is arranged in the axial direction of the universal joint, and cooperates with a sleeve of the clamping sleeve, and the receiving groove is further provided with a through hole through the convex arc surface, and then the sleeve is provided with a connecting locking member to protrude and protrude to Outside the convex arc surface, one end surface of one of the joint seats forms a concave curved surface, and is matched with the convex curved surface of the universal joint, and the center is provided with a consistent perforation and a sleeve through, and by the above structure, It constitutes an improvement of the bicycle front fork suspension structure.

Compared with the effect of the prior art: the shock absorber of the present invention is connected to the 10,000-way seat by the upper seat, and then the universal joint is matched with a connecting seat set at the second connecting end of the bicycle front fork, and the raft can be connected to the universal joint through the connecting seat. The seat forms a 360-degree universal yaw state, and it does withstand the vibration of the front wheel in various directions, and then squeezes the inner shaft and compresses the elastic member to achieve buffering and shock-absorbing effects, greatly improving the use of the shock absorber, and improving the riding of the bicycle.
