Abstract
The utility model relates to a motorcycle wheel hub, comprising a wheel hub axle tube and two spoke seats connected with the wheel hub axle tube and forming into an integration. The cylindrical surface of the spoke seat is arranged in average with a spoke installation boss, and a spoke hole is arranged on each spoke installation boss; the axial line of the spoke hole is vertical to the axial line of the wheel hub axle tube. The motorcycle wheel hub of the above structure is favourable for the processing and fillet of the spoke hole; furthermore, after the spoke is installed in the spoke hole, the cooperate area between the spoke and the spoke hole is larger, and the curvature on the position of installation of the spoke is smaller; consequently, the stress on the point of the installation bend is not concentrated, the spoke fractures uneasily, and the quality of the motorcycle is ensured.
Description
Technical field
The utility model relates to a kind of hub of motorcycle.
Technical background
Hub of motorcycle mainly reaches two width of cloth bar seat ears that combine as a whole with it by hub axle tube to be formed, and offers width of cloth cylindrical void on width of cloth bar seat ear, in order to motorcycle spoke bar to be installed.Width of cloth cylindrical void on existing its width of cloth bar seat ear of hub of motorcycle is the side (as shown in Figure 3) that is opened in width of cloth bar seat ear, width of cloth bar axially bored line and hub axle tube parallel axes or have angle.For the wheel hub that width of cloth bar axially bored line and hub axle tube axis have angle, when processing width of cloth cylindrical void, each width of cloth cylindrical void all needs the clamping location once, and it is very inconvenient to process, and influences production efficiency; Wheel hub for width of cloth bar axially bored line and hub axle tube parallel axes, though there is not the problem of multiple clamping in the processing of its width of cloth cylindrical void, but when the chamfering of processing width of cloth cylindrical void in width of cloth bar seat ear inboard, drill bit because of the limitation in space can not with the dead in line of width of cloth cylindrical void, but with width of cloth bar axially bored line have angle (shown in Figure 4), so make the inconvenience of width of cloth bar Hole chamfering, the chamfering that processes so simultaneously influences the installation quality of width of cloth bar to a certain extent.The wheel hub of above-mentioned two kinds of structures also has a common critical defect, because width of cloth cylindrical void is the side that is opened in width of cloth bar seat ear, after width of cloth bar is installed in the width of cloth cylindrical void, the curvature of installation position, width of cloth bar end excessive (as shown in Figure 5), make stress very concentrated, width of cloth bar ruptures easily in this knee, thereby has a strong impact on the quality of motor bike, even causes the generation of accident.
The utility model content
Technical problem to be solved in the utility model provides a kind of hub of motorcycle, to make things convenient for the processing of width of cloth cylindrical void, reduces the bending curvature that width of cloth bar is installed in back panel bar in the width of cloth cylindrical void simultaneously.
Hub of motorcycle described in the utility model, comprise hub axle tube and two width of cloth bar seat ears that combine as a whole with it, on the width of cloth bar seat ear face of cylinder, evenly be provided with width of cloth bar installation base, offer width of cloth cylindrical void on each width of cloth bar installation base, width of cloth bar axially bored line and hub axle tube axis normal.
The described width of cloth cylindrical void that is opened on each width of cloth bar installation base is two, width of cloth bar axially bored line on all width of cloth bar installation bases on each width of cloth bar seat ear lays respectively in two planes with the hub axle tube axis normal, even be positioned at same plane near the width of cloth bar axially bored line of width of cloth bar seat ear inboard on all width of cloth bar installation bases on each width of cloth bar seat ear, and on all width of cloth bar installation bases on each width of cloth bar seat ear near the width of cloth bar axially bored line common bits in the width of cloth bar seat ear outside in another plane.
Width of cloth bar axially bored line and hub axle tube axis on all width of cloth bar installation bases are equidistant.
The utility model is owing to have this kind structure, its width of cloth cylindrical void is to be opened on the width of cloth bar installation base on the width of cloth bar seat ear face of cylinder, but not be opened in the side of width of cloth bar seat ear, and width of cloth bar axially bored line and hub axle tube axis normal, when processing width of cloth cylindrical void, the clamping location of wheel hub is very easy to, during width of cloth bar Hole chamfering, drill axis can keep overlapping with width of cloth bar axially bored line, helps the processing and the chamfering of width of cloth cylindrical void like this; And when width of cloth bar is installed in width of cloth cylindrical void, it is the width of cloth cylindrical void that passes on the width of cloth bar installation base slight curvingly, width of cloth bar cooperates area bigger with width of cloth cylindrical void, after arrangement finishes, width of cloth bar is very little in the curvature of installation position, thereby width of cloth bar is not concentrated at the stress that the knee is installed,, guaranteed the quality of motor bike so width of cloth bar is not prone to phenomenon of rupture.

The specific embodiment
As shown in Figure 1, this hub of motorcycle comprises hub axle tube 4 and two width of cloth bar seat ears 1 that combine as a whole with it, two width of cloth bar seat ears 1 be positioned at hub axle tube 4 two ends and with hub axle tube 4 axis normal, on width of cloth bar seat ear 1 face of cylinder, evenly be provided with 8 width of cloth bar installation bases 2, width of cloth bar installation base 2 combines as a whole with width of cloth bar seat ear 1, the axis of width of cloth bar installation base 2 is by width of cloth bar seat ear 1 axis (being hub axle tube 4 axis), on each width of cloth bar installation base 2, offer two width of cloth cylindrical voids 3, width of cloth cylindrical void 3 axis and hub axle tube 4 axis normal, and vertical with the axis of width of cloth bar installation base 2.Width of cloth cylindrical void 3 axis on all width of cloth bar installation bases 2 on each width of cloth bar seat ear 1 lay respectively in two planes with hub axle tube 4 axis normal, even be positioned at same plane near width of cloth cylindrical void 3 axis of width of cloth bar seat ear inboard on all width of cloth bar installation bases 2 on each width of cloth bar seat ear 1, and on all width of cloth bar installation bases 2 on each width of cloth bar seat ear 1 near the width of cloth bar axially bored line common bits in the width of cloth bar seat ear outside in another plane.And width of cloth cylindrical void 3 axis and hub axle tube 4 axis on all width of cloth bar installation bases 2 are equidistant.
