Abstract
The utility model provides a motorcycle hub which comprises a hub main body (1), bearings (2), a liner bushing (3) and a supporting ring (4), wherein the two bearings (2) are respectively positioned at two ends of inner bores of the hub main body (1), the liner bushing (3) is arranged between the two bearings (2), the supporting ring (4) is sheathed at one end of the liner bushing (3), an annular groove (5) is arranged on a journal of the hub main body (1), which is used for assembling a chain wheel buffering body, and the annular groove (5) is internally provided with an O-shaped sealing ring (6). In the motorcycle hub, the O-shaped sealing ring is arranged on the journal of the hub main body, which is used for assembling the chain wheel buffering body, thus being capable of effectively preventing rainwater, sand and the like from entering supporting bearings of the hub through clearances between the buffering body and the hub, so as to ensure the bearings to be normally used, and prolonging the service life of the hub.
Description
Technical field
The utility model relates to motorcycle part, especially hub of motorcycle.
Background technology
On existing chain-driving motor bike, wheel hub by bearings on wheel shaft, one side of wheel hub also connects sprocket wheel by buffer body, although oil sealing will be installed in the bearing outer end at buffer body, reliable at bearing along the axial waterproof of wheel, but without any seal approach, rainwater, silt etc. enters in the backup bearing of wheel hub by the gap between buffer body and the wheel hub easily between buffer body and the wheel hub, has had a strong impact on the service life of wheel hub.
The utility model content
It is reliable that the purpose of this utility model provides a kind of sealing, guarantees that bearing is avoided rainwater, silt corrodes, and improves the hub of motorcycle in service life.
For achieving the above object, the utility model provides a kind of hub of motorcycle, include hub body, bearing, inner covering and bracing ring, two bearings lay respectively at the two ends of hub body endoporus, between two bearings inner covering is arranged, bracing ring is enclosed within an end of inner covering, is used for assembling at hub body on the axle journal of sprocket wheel buffer body and is provided with annular groove, and the O RunddichtringO is housed in the annular groove.
The utility model is owing to be used for assembling at hub body on the axle journal of sprocket wheel buffer body the O RunddichtringO is housed, can prevent effectively that rainwater, silt etc. from entering in the backup bearing of wheel hub by the gap between buffer body and the wheel hub, guarantee the normal use of bearing, prolonged the service life of wheel hub.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Among the figure: 1. hub body; 2. bearing; 3. inner covering; 4. bracing ring; 5. annular groove; 6.O RunddichtringO.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1 and Figure 2, hub of motorcycle described in the utility model, have hub body 1, bearing 2, inner covering 3 and bracing ring 4, two bearings 2 lay respectively at the two ends of hub body 1 endoporus, between two bearings 2 inner covering 3 is arranged, bracing ring 4 is enclosed within an end of inner covering 3, is used for assembling at hub body 1 on the axle journal of sprocket wheel buffer body and is provided with annular groove 5, and annular groove is equipped with O RunddichtringO 6 for 5 li.
Owing to be used for assembling at hub body 1 on the axle journal of sprocket wheel buffer body O RunddichtringO 6 be housed, can prevent effectively that rainwater, silt etc. from entering in the backup bearing of wheel hub by the gap between buffer body and the wheel hub, guarantee the normal use of bearing, prolonged the service life of wheel hub.
