Abstract
The utility model discloses a bicycle axle comprises an axle body, an axle body pipe arranged on the outer side of the axle body in a sleeved mode, axle bumpers arranged at the two ends of the axle body pipe, a bearing arranged between the axle body and an end portion the axle body pipe, and wheel fixing parts arranged at the two ends of the axle body. One end of the axle body is sleeved with a protection sleeve which is provided with a containing cavity, and the bearing and the wheel fixing parts are located into the containing cavity of the protection sleeve. The bearing between the axle body of the axle and the end portion of the axle body pipe of the axle replaces a traditional ball, transmission is good, friction is reduced, the transmission efficiency of the axle is enhanced, and the service life of the axle is prolonged. One end of the axle body is provided with the protection sleeve, and therefore dust is effectively prevented from falling into the bearing. Meanwhile, the protection sleeve effectively ensures that the wheel fixing parts and other parts are protected against damage caused by collision in the process of transporting and using the axle, and therefore the maintenance frequency is greatly reduced.
Description
Technical field
The utility model relates to a kind of bicycle shaft.
Background technology
At present, bicycle becomes the vehicle of people's indispensability already, various bicycles are enriching market, meet people's needs, bicycle shaft is mainly by axis body pipe, axis body, ball, coupling nut forms, with time be mainly to reduce axis body friction force when rotated by being arranged on the rolling of ball between bushed bearing and axis body, yet ball is easy in use for some time, there is distortion and broken, make axis body occur wearing and tearing, reduced the service life of axletree, and in the use procedure of axletree, between pipe spreader and axis body, be very easy to overstock dust, make the lubricant effect variation of ball, cause axletree to use inconvenient, and axletree in use, each parts of axle head very easily cause damage because of collision.
Utility model content
The purpose of this utility model is in order to solve the existing defect of bicycle shaft in prior art, to provide a kind of friction force little, prevents that dust from falling in axis body and preventing the bicycle shaft that causes damage of components because of collision.
To achieve these goals, the technical solution adopted in the utility model is:
A bicycle shaft, comprises axis body, is sleeved on the axis body pipe in this axis body outside, is arranged on the axle bumper at described axis body pipe two ends, the wheel fixing part that is arranged on the bearing between described axis body and axis body tube end and is located at described axis body two ends;
One end of described axis body is arranged with a protecting sleeve, and this protecting sleeve has container cavity, and described bearing and wheel fixing part are positioned at the container cavity of described protecting sleeve.
Above-mentioned a kind of bicycle shaft, the side of described axle bumper is provided with a plurality of projections.
Above-mentioned a kind of bicycle shaft, described axle bumper is disc.
Above-mentioned a kind of bicycle shaft, described protecting sleeve comprises integrated peristome and accommodation section, the side close contact of peristome and described axle bumper.
Above-mentioned a kind of bicycle shaft, the peristome of described protecting sleeve is rounded.
Above-mentioned a kind of bicycle shaft, the peristome of described protecting sleeve is corresponding with the diameter of described axle bumper.
The beneficial effects of the utility model are: the bearing being provided with between the axis body of this axletree and axis body tube end has replaced traditional ball; transmission is good; reduced friction; transmission efficiency and the service life of axletree have been strengthened; the protecting sleeve being provided with in axis body one end; effectively prevent that dust from falling into bearing, simultaneously protecting sleeve has also guaranteed that axletree wheel fixing part and other parts in transportation and use procedure can not cause because of collision damage effectively, less widely frequency of maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is exploded view of the present utility model.
The specific embodiment
For making that architectural feature of the present utility model and the effect reached are had and further understand and be familiar with, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figure 1 and Figure 2, a kind of bicycle shaft, comprise axis body 1, be sleeved on the axis body pipe 2 in this axis body 1 outside, be arranged on the axle bumper 3 at axis body pipe 2 two ends, the wheel fixing part 5 that is arranged on the bearing 4 between axis body 1 and axis body pipe 2 ends and is located at axis body 1 two ends, cycle wheel is fixed on axis body 1 by wheel fixing part 5.
In the utility model; the side of axle bumper 3 is provided with a plurality of projections; axle bumper 3 is disc; one end of axis body 1 is arranged with a protecting sleeve 6; protecting sleeve 6 comprises integrated peristome 7 and accommodation section 8; the inner side of accommodation section 8 has container cavity, and bearing 4 and wheel fixing part 5 are positioned at the container cavity of protecting sleeve 6.
The opening 7 of protecting sleeve is rounded, and diameter is corresponding with the diameter of axle bumper 3, the peristome 7 of protecting sleeve 9 and the side close contact of axle bumper 3.
The bearing 4 being provided with between the axis body 1 of this axletree and axis body pipe 2 ends has replaced traditional ball; transmission is good; reduced friction; transmission efficiency and the service life of axletree have been strengthened; the protecting sleeve 6 being provided with in axis body one end; effectively prevent that dust from falling into bearing, simultaneously protecting sleeve has also guaranteed that axletree wheel fixing part and other parts in transportation and use procedure can not cause because of collision damage effectively, less widely frequency of maintenance.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification sheets, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
