The purpose of this utility model is achieved in that a kind of multiple spline hub, comprise hub body, hub body centre hole is embedded with spline, hub body is coaxially arranged with braking iron ring with spline, described spline inner ring is provided with some serrations, described spline periphery is provided with one deck convex outer key and at least convex key of one deck internal layer, convex outer key is corresponding with the outside of hub body, convex outer key and every layer of convex key of internal layer are uniformly distributed in a circumferential direction, setting is axially aligned between the convex key of internal layer of different layers, convex outer key and the convex key circumference of internal layer stagger an angle, described hub body centre hole is axially arranged with along it some axial grooves holding convex outer key and insert simultaneously, hub body centre hole and the axial groove angle that staggers is provided with keyway, angle in circular segment between keyway and axial groove equals the angle in circular segment between the convex key of internal layer and convex outer key, the convex key of described internal layer is crossed one by one to win to coordinate and is arranged in corresponding keyway, convex outer key is crossed win cooperation simultaneously and is arranged in axial groove, be provided with sector channel between axial groove and keyway, described sector channel can hold the corresponding convex key of internal layer and rotate to splined end from axial groove, described hub body end face outside is provided with stop screw and conflicts on the outer face of the convex key of the internal layer of outermost side.
Manufacture for ease of installing, reliable transmission simultaneously, described convex outer key and the convex key of internal layer are respectively equipped with four groups in a circumferential direction, the often phase 90 ° between group of convex outer key, the convex key of internal layer often between group phase difference be also 90 °, the phase between convex outer key and the convex key of internal layer 45 °.This structure is convenient to processing and is installed.
As further improvement of the utility model, the convex key of described internal layer is provided with two-layer.The convex key of two-layer internal layer has interval in the axial direction, and the internal stress that can reduce expands with heat and contract with cold produces is destroyed.
Clean and tidy for ensureing that surface originally carried by wheel hub, described stop screw is hexagon socket countersunk flat cap head screw.
In the utility model, between spline with hub body be not only multiple spot cross win coordinate, there is elastic allowance, the change of expanding with heat and contract with cold can be adapted to, not easily produce larger internal stress, meanwhile, additionally use stop screw and prevent spline from coming off from keyway, even if spline departs from from keyway, owing to there being the stop of axial groove, wheel can produce certain swing, driving person can be discovered to some extent, and will directly cause wheel to come off.Therefore, when this device is used on wheel, its structure is simple, uses more reliable.More firm owing to connecting, when carrying out metalworking, can ensure that spline can not be shifted when by larger axial force.This device can be used safely on wheel, can ensure transmission and braking reliably, easy to assembly, use safety.
