Abstract

The utility model relates to a bicycle mixed rim structure with the combination of composite material and aluminium material. The bicycle mixed rim structure is mainly characterized in that the composite material at the inner side end of a rim is made into a spoke fixing ring and the aluminium material positioned at the outer side end of the rim is made into a tyre protecting ring, wherein, original reinforced ribs which are connected with the left and the right sides of the tyre protecting ring face to the spoke fixing ring end, second reinforced ribs which are used for gluing with the outer support wall of the spoke fixing ring and assisting the outer support strength of the outer support wall of the spoke fixing ring are additionally arranged at a certain interval. The second reinforced ribs used for assisting the outer support effect of the spoke fixing ring of the composite material are also the aluminium materials with high temperature resistance and have a certain distance with the original immanent reinforced ribs and the heat insulation effect. So the softening deformation and the peel-off of the spoke fixing ring of the composite material can not be caused under the high temperature caused by the brake of the bicycle and the deformation of the wheels can also not be generated.

Description

The hybrid rim structure of bicycle that combines with aluminium by composite wood

(1) technical field:

The utility model relates to a kind of hybrid rim structure of bicycle that is combined with aluminium by composite wood, belongs to bicycle accessories.

(2) background technology:

Strengthen because of environmental consciousness in recent years, therefore often can see many common people, or utilize bicycle (or bicycle) as the incommutation instrument in order to save money at leisure time (or bicycle) by bike.The wheel rim of known bicycle has a kind of hybrid wheel rim 10 (as shown in Figure 1, 2) that is, the spoke set collar 11 of its wheel rim medial extremity is made (being the carbon fiber material) for composite wood, and 12 on the antiabortive ring of the tire of wheel rim external side end is that aluminium is made.Wherein, the reinforced ribs 120 (as shown in Figure 2) that the antiabortive ring 12 of tire links left and right side is the middle place that is positioned at the antiabortive ring 12 of tire, the spoke set collar 11 that composite wood is made supports wall 110 outward and composes one with reinforced ribs 120 walls in the face of reinforced ribs 120 end moulding one outer support wall 110.Yet when bicycle brake, brake lining is the antiabortive ring 12 both sides external wall friction made from aluminium of tire, the friction temperature of the antiabortive ring 12 of Lining and tire can be up to 150 ℃ during brake, antiabortive ring 12 thermal endurances of the tire that aluminium is made can reach 300 ℃, so, the high temperature that is caused that rubs during brake can't harm the antiabortive ring 12 of tire, but spoke set collar 11 its thermal endurances that composite wood is made only are about 80～100 ℃, the high temperature that when bicycle brake, is caused, because of the heat conducting high temperature that concerns can conduct to the outer support wall 110 of composite wood spoke set collar 11 via the antiabortive ring 12 both sides friction faces of aluminium tire, outer support wall 110 is because composite wood can't bear this high temperature, therefore cause the outer support wall 110 of composite wood spoke set collar 11 softening, outer support wall 110 1 softens, whole spoke set collar 11 intensity reduce immediately, and then cause the bicycle wheel distortion, influence brake function.

(3) utility model content:

The purpose of this utility model is to provide a kind of hybrid rim structure of bicycle that is combined with aluminium by composite wood, and to solve defective of the prior art, the spoke set collar that prevents composite wood is the softening transform and the problem of peeling off under bicycle brake high temperature.

A kind of hybrid rim structure of bicycle that combines with aluminium by composite wood of the utility model, it is to link the original intrinsic reinforced ribs of left and right side in the face of spoke set collar one end at the antiabortive ring of tire, setting up one second reinforced ribs apart from a determining deviation place, support the wall gummed outward in order to spoke set collar, support outward with auxiliary spoke set collar with composite wood.Second reinforced ribs in order to the outer support of assisted recombination material spoke set collar also is resistant to elevated temperatures aluminium, and with the former first reinforced ribs tool, one determining deviation, can separate and reduce high temperature, therefore, the spoke set collar that can not cause composite wood softening transform and peeling off under bicycle brake high temperature, and wheel can not be out of shape yet.

Again the technical solution of the utility model is repeated as follows below: the spoke set collar that this wheel rim is made by a composite wood, and the two gummed of the antiabortive ring of tire that aluminium is made forms; Wherein, the antiabortive ring in the middle of both sides of the tire made of aluminium links with one first reinforced ribs; It is characterized in that: the antiabortive end distance of the spoke set collar of making in first reinforced ribs towards composite wood that encircles of tire is from a determining deviation place, set up one second reinforced ribs, this second reinforced ribs is also in order to link the left and right sides wall of the antiabortive ring of tire, the Lining drag friction face in the middle of the antiabortive ring of its position deviation tire both sides.

Wherein, this second reinforced ribs and first reinforced ribs can be arranged in parallel with same curvature bending to spoke set collar end simultaneously.

A kind of hybrid rim structure of bicycle that combines with aluminium by composite wood of the utility model, its advantage and effect are: the spoke set collar that this structure can be avoided composite wood softening transform and peeling off under bicycle brake high temperature, and can prevent the wheel distortion.

(5) specific embodiment:

A kind of hybrid rim structure of bicycle that combines with aluminium by composite wood of the utility model, its first embodiment as shown in Figure 3, wheel rim 20 also is the spoke set collar of being made by a composite wood 21, and antiabortive ring 22 the two gummed of tire of making of aluminium form.Wherein the antiabortive ring 22 of tire made of aluminium links with one first reinforced ribs 220 in the middle of both sides.Main improvement of the present utility model is:

Spoke set collar 21 end distances that the antiabortive ring 22 of tire is made in first reinforced ribs 220 towards composite wood are from a spacing place, set up one second reinforced ribs 221, this second reinforced ribs 221 is also in order to linking the left and right sides wall of the antiabortive ring 22 of tire, and the Lining drag friction face 222 in the middle of the antiabortive ring of position deviation tire 22 two sides.Spoke set collar 21 tools support the outer support wall 210 of function outward, are and second reinforced ribs, 221 gummeds.

Because the outer support wall 210 of spoke set collar 21 is and second reinforced ribs, 221 gummeds of the antiabortive ring 22 of tire second reinforced ribs 221 to be had promote the outer effect that supports wall 210 outer support functions.And 220 tool one separation pitch of second reinforced ribs 221 and first reinforced ribs have effect of heat insulation, and the highest antiabortive ring 22 friction faces of tire 222 corresponding positions of second reinforced ribs, 221 position deviation cars when brake Lining friction temperature.So, even the temperature of antiabortive ring 22 friction faces 222 of car when brake tire up to 150 ℃, can not cause the softening transform situation to the outer support wall 210 of spoke set collar 21 yet.

Secondly, see also shown in Figure 4ly, this first and second reinforced ribs 220,221 also can be done same curvature bending to spoke set collar 21 ends and be arranged in parallel.

Above-mentioned two embodiment, reinforced ribs (first and second reinforced ribs) is arranged to two, and reinforced ribs also can be provided with more than two.
