Abstract
The invention discloses a bicycle wheel rim structure which comprises a hub, spokes and a wheel rim, wherein both ends of each spoke are respectively connected with the hub and the wheel rim, five spokes are arranged in each spoke group, the spokes in each spoke group are arranged and woven in the proportion of 2: 3, and the hub and the wheel rim are connected with at least three spoke groups. The bicycle wheel rim structure can balance the acting forces of the hub and each spoke, the stress on each spoke connected with both sides of the hub is more balanced, and the acting forces applied to the spokes are basically the same with little difference; a variable force of thrust force or pulling force is not alternately applied to the spokes by the hub and the wheel rim; the fatigue effect of the spokes can be greatly reduced and eliminated, thereby prolonging the service life; the integral balance of the bicycle wheel rim is better, and the bicycle is more comfortable when ridden.
Description
Technical field:
The present invention relates to technical field of bicycles, especially relate to a kind of bicycle rim structure.
Background technology:
Raising along with living standards of the people; The raising of the consciousness of environmental protection and body-building demand; Bicycle, more and more receives people and likes also as a kind of health and fitness facilities both as a kind of running vehicle; Bicycle is also had higher requirement the comfort when driving, the balance of bicycle and durability etc.
Wherein, be connected through the spoke silk between the wheel rim of bicycle and the flower-drum, the spoke silk is that the ratio with 1:1 is cross-linked the left and right sides at flower-drum; And flower-drum one side of bicycle is provided with chain drive or brake gear (like disc brake apparatus); Chain drive or brake gear apply an application force to flower-drum one side, and corresponding to the chain drive of rear wheel, perhaps the disc brake apparatus of front vehicle wheel, rear wheel all is like this; Chain drive or brake gear make left and right sides, each spoke silk and the equal discontinuity equalization of wheel rim of flower-drum; The balance quality of bicycle is relatively poor, and each spoke thread tension is uneven, and wherein the stressed bigger normal phase of spoke silk of part receives thrust and the alternately effect of the variation power of appearance of pulling force; There is serious fatigue effect; Be very easy to be damaged, its service life is much smaller than due normal service life, serious reduction of service life.
For addressing this problem, the existing patent No. is that " 01244882.6 ", patent name are the Chinese patent of " with the bicycle rim of multiple proportions coupling spoke silk ", discloses a solution; Its spoke silk is that the ratio with 1:2 is cross-linked the left and right sides at flower-drum, and its weaving rule is that common geometric ratio spacing is interlocked, and this scheme still can not address the above problem; The suffered effect of spoke silk in the spoke silk quantity side how is less; The suffered effect of spoke silk in the many side of spoke silk quantity is bigger, and for single spoke silk, flower-drum is to each spoke silk application force overbalance still; Still there is the normal phase of part spoke silk to receive thrust and the tension that alternately occurs; Still have serious fatigue effect, be very easy to be damaged, service life is still shorter.Therefore be necessary to improve.
