Abstract
The invention provides an aluminum alloy bicycle rim, which comprises a rim (1), wherein the section of the rim (1) is provided with two side walls (2); the bottom ends of the two side walls (2) are connected with each other through a connecting component A (3); the upper-middle parts of the two side walls (2) are connected with each other through a connecting component B (4); the upper parts of the two side walls (2) and the connecting part B (4) form a U shape with an upward opening; the U-shaped top is provided with two upper bumps (5); the lower ends of the two side walls (2) extend downwards respectively to from lower bumps (6). The upper part of the two side walls (2) and the connecting component B (4) form the U shape with the upward opening, and the connecting component B (4) can resist the deformation of the connecting component A (3) under the action of pulling force of spokes or pressure transmitted by tires on an uneven road, so that the strength and deformation resistance of the rim (1) are enhanced, and the running stability of a bicycle is improved.
Description
Technical field
The present invention relates to bicycle field, relate in particular to a kind of aluminum alloy bicycle rim.
Background technology
Instantly, because the world advocates energy-saving and emission-reduction on a large scale, bicycle has become the most popular walking-replacing tool in the whole world according to own convenient, practical characteristic.Along with the continuous progress of science and technology, many new technology are applied on bicycle, make the performance of bicycle more and more advanced.The cycle frame that for example aluminum alloy, magnesium alloy, titanium alloy and carbon fiber are made, greatly reduces the weight of bicycle; Multi-gear transmission mechanism makes the speed of bicycle more and more faster.And when bicycle performance significantly improves, bicycle traveling comfort is also more and more paid close attention to by consumers in general.
The wheel of bicycle is the vitals that keeps bicycle to operate steadily, the steel rim finally of wooden rim from the beginning, its material is constantly changing, because aluminum alloy with respect to magnesium alloy, admire alloy and carbon fibre material price more cheap, and there is lightweight, the characteristic of can not getting rusty, therefore, be subject to consumers in general's favor.
At present common aluminum alloy bicycle rim has two kinds of single layer car rim and double-deck rims, single layer car rim is because spoke cap directly contacts with the inner tube of a tyre, easily gall the inner tube of a tyre, double-deck rim has overcome this shortcoming, strengthened again intensity simultaneously, therefore, double-deck rim has advantages of larger with respect to single layer car rim, and is widely adopted.But the first connecting portion of rim is in the effect of spoke pulling force for a long time, easily deforms, therefore, after long-time use, easily destroys the circularity of rim, thereby affect bicycle traveling comfort.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the aluminum alloy bicycle rim that a kind of stationarity is good, resistance to corrosion is strong, comprise rim, described rim cross section has two sidewalls, article two, the bottom of sidewall interconnects by link A, and the middle and upper part of two sidewalls interconnects by link B, and the top of two sidewalls and link B form the U-shaped of opening upwards, U-shaped top is provided with two upper process, and the lower end of two sidewalls extends to form respectively lower process downwards.The end of described lower process is circular arc.
The length of described link A is less than the length of link B.
On the middle and upper part outside face of two described sidewalls, be respectively equipped with groove.
Described link A and two lower process form the ∩ shape that Open Side Down.
Beneficial effect of the present invention: the top of two sidewalls and link B form the U-shaped of opening upwards, this U-shaped structure design makes link B when being subject to the pulling force of spoke or bearing the pressure of tire transmission due to Uneven road, can resist the distortion of link A, thereby strengthen intensity and the non-deformability of rim, increase the stationarity of cycle racing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the schematic cross-section of Fig. 1 of the present invention.
The specific embodiment
As Fig. 1, shown in Fig. 2, aluminum alloy bicycle rim, comprise rim 1, described rim 1 cross section has two sidewalls 2, article two, the bottom of sidewall 2 interconnects by link A3 respectively, article two, the middle and upper part of sidewall 2 interconnects by link B4 respectively, article two, the top of sidewall 2 and link B4 form the U-shaped of opening upwards, U-shaped top is provided with two upper process 5, the profile of this circular arc and bike tyre is suitable, this structure can more effectively be alleviated the pressure of 5 pairs of tires of upper process, thereby protection tire, article two, the lower end of sidewall 2 extends to form respectively lower process 6 downwards.After turning, appear bright aluminium true qualities, form sharp contrast with the integral color of spraying, give a kind of fresh and new sensation of people.The end of described lower process 6 is circular arc.The length of described link A3 is less than the length of link B4.On the middle and upper part outside face of two described sidewalls 2, be respectively equipped with groove 7.Described link A3 and two lower process 6 form the ∩ shape that Open Side Down.
The invention is not restricted to above-mentioned embodiment, anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all fall into protection scope of the present invention it.
