Abstract
The utility model relates to a bicycle part, particularly to a bicycle hub which is suitable for the high-speed running of an electric bicycle and a fuel booster bicycle. The utility model comprises an outer sleeve of the hub, a shaft roller and clamp nuts. The utility model is characterized in that rolling bearings are arranged in the hubs on both ends of the outer sleeve of the hub, a flanging lining sleeve is arranged between an inner ring of each of the bearings and the shaft roller, and supporting tubes are sheathed on the shaft roller and between the inner rings of each two bearings on both sides. The utility model has the advantages that the high-speed bearings replace the original loose steel balls, a high-speed, fuel perfusion and silent free wheel with an integral core body replaces the original dry-bead and fuel-free wheel, abrasion resistance and sensitivity are enhanced, and the utility model perfects the electric bicycle and the booster bicycle and avoids the trouble of frequent repair and part replacement.
Description
Technical field
The utility model relates to a kind of attachments of a bicycle, particularly a kind of bicycle hub of running at high speed that is suitable for Electrical Bicycle and fuel bicycle use.
Background technology
Along with the raising of people's living standard, rhythm of life is more and more faster, and Electrical Bicycle obtains people's favor soon, flexibly and gradually with its speed.But, hold friction that can't stand the Electrical Bicycle twirl because standard bicycle axle skin uses ball in bulk to cooperate with the axle bowl, thereby increased the part maintenance of car and changed frequency.
The utility model content
The utility model is intended to overcome above-mentioned deficiency of the prior art, and a kind of bicycle hub of running at high speed that Electrical Bicycle and fuel bicycle use that is suitable for is provided, the high-speed operation that can adapt to Electrical Bicycle can be saved axle bowl, ball and three parts of axle bumper again.
The technical scheme that the utility model adopted is for achieving the above object: a kind of bicycle hub, comprise a skin overcoat, beaming roller and clamp nut, be equipped with antifriction-bearing box in the flower-drum at described axle skin overcoat two ends, be provided with the flange lining between bearing inner ring and the beaming roller, between the bearing inner ring of on the beaming roller and both sides, be socketed with support tube.
The beneficial effects of the utility model are: by diffusing ball and axle bowl and the axle bumper that antifriction-bearing box has replaced original standard bicycle axle skin to use, strengthened the fastness to rubbing of bearing.Adapt to running at high speed of Electrical Bicycle and boosted vehicle, avoid the trouble of often maintenance and change part.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A partial enlarged drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
A kind of bicycle hub shown in Fig. 1-2, the clamp nut 3 that comprises a skin overcoat 1, beaming roller 2 and two ends, be equipped with antifriction-bearing box 4 among the flower-drum 1-1 at described axle skin overcoat two ends, bearing adopts the high speed miniature bearing, all be with flange lining 5 between the bearing inner ring 4-1 of both sides and the beaming roller 2, to keep this tolerance clearance reasonable.Be socketed with support tube 6 on the beaming roller and between the bearing inner ring of both sides, do not turning round flexibly so that do not influence bearing during fastening bearing, support tube is that metallic material is made, and is of a size of Φ 14 * 2.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
