It will be appreciated that in order to enable the rim to be extruded on a metal extrusion process, any radial cross-sectional profile of the rim is substantially uniform irrespective of the additional structure formed on the rim by subsequent hole making or the like processes of the extrusion process.

The spoke motorcycle wheel is described below in two specific embodiments.

Example one

Referring to fig. 1 to 5, the present embodiment provides a spoked motorcycle wheel comprising a rim 1 and a hub 2, the rim 1 being fastened to the hub 2 by a plurality of individual spokes 3. The rim 1 comprises an inner rim 11 and an outer rim 12 which are formed into a whole, and in order to facilitate the rim 1 of the spoke type motorcycle wheel to be obtained by extrusion through a metal extrusion forming process, the inner rim 11 and the outer rim 12 are in a regular annular structure with any radial section pattern consistent.

Wherein, the inner rim 11 is arranged at the inner side of the outer rim 12 along the radial direction of the rim 1 and is configured to connect the spokes 3, which enables the outer rim 12 to obtain a radial outer end surface without holes, and the outer end surface is configured to joint and hold the tire bead, thereby ensuring the vacuum degree of the whole spoke and rim group without air leakage between the tire bead of the vacuum tire and the outer rim 12 due to the holes for connecting the spokes 3 when the vacuum tire is adopted by the spoke type motorcycle wheel.

To attach the spoke 3, the inner rim 11 has a circumferential array of puller holes 4, each puller hole 4 having an outer periphery surrounding a puller seat 41 formed with a threaded spoke puller 5, the spoke puller 5 being capable of pulling the spoke 3 to secure the spoke 3 to the rim 1. The hub 2 has a circumferential array of hat holes 6, the hat holes 6 being able to receive hat spokes 7, the hat spokes 7 being able to thread the spokes 3 in order to fasten the spokes 3 to the hub 2.

During assembly, the spoke puller 5 is sleeved into the raised head end 31 of the spoke 3, the spoke puller 5 is locked on the puller seat 41, the spoke cap 7 and the threaded end 32 of the spoke 3 are locked to the cap hole 6 of the hub 2, and the tensioning degree of the spoke 3 is adjusted by rotating the spoke cap 7, so that the roundness and the plane runout of the whole vacuum tire rim 1 system of the spoke 3 are ensured to meet the standard range.

In the embodiment, the spokes 3 of the complex casting wheel can be replaced by integral multiples of 4 (such as 32, 36, 40 and the like), so that the weight of the spoke type motorcycle wheel and the complexity of the spokes are greatly reduced, and the technical barriers and the casting defects in the casting process of the rim 1 are avoided. Compared with a spoke plate wheel, the motorcycle wheel with the spoke 3 suspension structure can reasonably decompose the external impact force borne by the rim 1 into dozens of points (namely the number of specifically arranged spokes 3) from the concentrated stress condition of a few originally fixed (namely the number of specifically arranged spoke plates). Compared with a cast integrated wheel, the buffering force is reduced by more than 6 times, so that the overall impact strength of the original spoke plate wheel can be borne by more than 6 times theoretically, and the overall strength of the spoke 3 wheel is effectively improved. In addition, the spokes 3 are elastic elements, can absorb vibration and impact force with certain strength, can better protect the rim 1 when the rim is stressed, prevent the rim 1 from deforming, and ensure the integrity of the vacuum structure of the spoke type motorcycle wheel.

As shown in fig. 3, the stress on the entire structure of the spoke type motorcycle wheel can be optimized by the double-layer structure of the rim 1 formed by the inner rim 11 and the outer rim 12, for example, the joint between the inner rim 11 and the outer rim 12 can be set to be smooth transition, and further, the inner rim 11 can be arched to be convex toward the radial inner side of the rim 1, so that the strength of the spoke type motorcycle wheel can be improved by 42% or more compared with a cast wheel under the same specific weight.

In addition, the double-layer rim can effectively reduce tire noise, the double-layer structure of the rim 1 also has a good elastic deformation space, when the wheel bears external impact force, the inner rim 11 can absorb the impact force through deformation, the overall sealing performance between the outer rim 12 and the tire bead cannot be influenced, tire burst and air leakage are prevented, and the accident rate is reduced.

A spoke slider 5 can be provided at the radially outer end (i.e. the nose end 31) of each spoke 3, the spoke slider 5 being threadedly fastened to the slider seat 41 radially outwardly of the rim 1. The corresponding spoke 3 can be tightened and pulled upon forward rotation of the spoke puller 5, and the spoke 3 can be released upon reverse rotation of the spoke puller 5. That is, in the present embodiment, the spoke slider 5 is used to fix one end of the spoke 3 to the rim 1 at the time of assembly. The spoke cap 7 can then be arranged at the radially inner end (i.e. the threaded end 32) of each spoke 3. The spoke caps 7 can be threaded onto the flanges 21 of the axial ends of the hub 2 radially outwards of the rim 1, tensioning the corresponding spokes 3 when the spoke caps 7 are rotated forward, and loosening or even releasing the spokes 3 when the spoke caps 7 are rotated in the reverse direction. That is, in the present embodiment, the spoke caps 7 are used to fix the other ends of the spokes 3 to the hub 2 at the time of assembly, and to adjust the tension of the spokes 3 during the process of maintaining and calibrating the spoke motorcycle wheel.

In the embodiment, as shown in fig. 4, the flanges 21 at the two axial ends of the hub 2 may be provided with a circumferential array of hat holes 6 to equalize the stress on the hub 2, and the spokes 3 may be connected between the rim 1 and the hub 2 in a staggered manner to meet the mechanical performance requirement. Preferably, in the present embodiment, the axis of the cap hole 6 is inclined inward of the hub 2 in the radial direction of the rim 1 to be suitable for the assembling work.

Preferably, the circumferential array of puller holes 4 is provided as a continuous zigzag staggered structure in which each puller hole 4 is axially offset to the side opposite each circumferentially adjacent puller hole 4 to equalize the force on the rim 1 and meet the mechanical performance requirements.

In this embodiment, the spokes 3 can use elbow spokes to effectively prevent the autorotation problem of the spokes 3 during the use. Specifically, the spoke 3 comprises a first section 33 and a second section 34 which are connected in a bent manner, wherein one end of the first section 33, which faces away from the second section 34, is provided with a thread which can be screwed with the spoke cap 7, and one end of the second section 34, which faces away from the first section 33, is provided with a raised head which can be clamped on the spoke puller 5.

Therefore, it should be noted that configuring the rim 1 to have a complete, imperforate radially outer end face may be understood as providing no other through holes on the radially outer end face of the rim 1 except for the valve core hole 13 through which the valve core 8 is inserted.

Specifically, in the present embodiment, the plurality of spokes 3 are evenly pulled to the periphery of the hub 2. The inner rim 11 is arranged on the inner side of the outer rim 12 along the radial direction of the rim 1, the inner rim 11 is provided with a circumferential array of bar cap holes 6, the periphery of each bar cap hole 6 surrounds a bar cap seat 61 formed by screwing the spoke cap component, and the bar cap component 9 can screw the spoke 3 so as to tension the spoke 3 between the rim 1 and the hub 2.
