Abstract
The utility model discloses a kind of wheel spokes, the disc-shaped structure of spoke, including centrally located disc and around the spoke frame of disc setting, center positioning hole is equipped in the middle part of disc, multiple bolts hole are additionally provided on disc, these bolts hole are arranged along the axle location hole circular array, and spoke frame is equipped with multiple heat release holes, these heat release holes are arranged around multiple bolt hole circular array；Spoke frame around each heat release hole is equipped with multiple stress apertures around heat release hole setting.It has the following advantages: can effectively prevent the crackle further expansion around heat release hole, spoke and wheel rim separation caused by reducing because of heat release hole crackle, and generate great accident, both Spoke Strength and safe application performance be can guarantee, the weight at spoke heat release hole can be mitigated again, the overall weight for alleviating wheel extends the service life of spoke.
Description
Technical field
The utility model relates to a kind of wheel spokes.
Background technique
Wheel generally includes tire, wheel rim, spoke and wheel hub, and tire is mounted on wheel rim, and wheel hub is used to connect with axle,
The effect of spoke is then connection wheel rim and wheel hub.Traditional wheel is single-piece wheel rim and single-piece spoke Combination Welding, and spoke is rotation
Reduction process is pressed, position is equipped with multiple heat release holes among spoke plane and end face, during wheels travel, due to friendship loaded
The influence of varying stress often cracks between heat release hole and heat release hole and wheel is caused to fail.Heat release hole as wheel hub and
The branch of tire withstands forces main positions, can also generate fracture by fatigue phenomenon in the case where repeatedly stress acts on repeatedly.
Utility model content
The utility model provides a kind of wheel spoke, and which overcome the deficiencies in the prior art described in background technology.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of wheel spoke, the disc-shaped structure of spoke, including centrally located disc and around the spoke frame of disc setting, spoke
Be equipped with center positioning hole in the middle part of plate, be additionally provided with multiple bolts hole on disc, these bolts hole along the center positioning hole in a ring
Array arrangement, spoke frame are equipped with multiple heat release holes, these heat release holes are arranged around multiple bolt hole circular array；It is each to dissipate
Spoke frame around hot hole is equipped with multiple stress apertures around heat release hole setting.
Among one embodiment: those stress apertures are laid along around each heat release hole in closed ring uniform intervals.
Among one embodiment: those stress apertures are laid along around each heat release hole in open annular uniform intervals.
Among one embodiment: the diameter of the stress aperture is 1.0-10mm.
Among one embodiment: the diameter of the stress aperture is 2.0mm.
Among one embodiment: the stress aperture has sharp angle R0.5-R2.0.
Among one embodiment: the stress aperture has sharp angle R1.0.
The technical program compared with the background art, it has the following advantages:
The spoke splits heat release hole generation in the multiple stress apertures of each heat release hole periphery design, wheel spoke is loaded
When line, it can effectively prevent the crackle further expansion around heat release hole, spoke and wheel rim caused by reducing because of heat release hole crackle
Separation, and great accident is generated, it not only can guarantee Spoke Strength and safe application performance, but also can mitigate at spoke heat release hole
Weight alleviates the overall weight of wheel, extends the service life of spoke.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 depicts the schematic front view of wheel spoke and wheel rim.
Fig. 2 depicts wheel spoke and wheel rim left view schematic diagram.
Fig. 3 depicts wheel spoke and wheel rim schematic three dimensional views.
Specific embodiment
It please refers to Fig. 1 to Fig. 3, a kind of wheel spoke, the disc-shaped structure of spoke, including centrally located disc 11 and encloses
It is equipped with center positioning hole 111 in the middle part of the spoke frame 12 of the setting of disc 11, disc 11, is additionally provided with multiple bolts hole on disc 11
112, these bolts hole 112 are arranged along 111 circular array of center positioning hole, and spoke frame 12 is equipped with multiple heat release holes 121,
These heat release holes 121 are arranged around multiple 112 circular array of bolt hole；It is set on spoke frame 12 around each heat release hole 121
There are multiple stress apertures 122 around the heat release hole 121 setting.
In one better embodiment, those stress apertures 122 along around each heat release hole 121 be in closed ring it is uniform between
Every laying, i.e., multiple stress apertures 122 surround a closed annular ring around heat release hole 121.
In another better embodiment, those stress apertures 122 are along uniform in open annular around each heat release hole 121
Interval is laid, i.e., multiple stress apertures 122 surround an annular ring with opening around heat release hole 121, can also be called arc
Circle.
The diameter of the stress aperture 122 is 1.0-10mm, it is preferable that the diameter of the stress aperture 122 is 2.0mm.
The burr generation on stress aperture 122, which scrapes to injure, in order to prevent influences wheel appearance, which has
Sharp angle R0.5-R2.0, it is preferable that the stress aperture 122 has sharp angle R1.0.
The above, only the utility model preferred embodiment, therefore, it cannot be limited according to, and the utility model is implemented
It is practical new to should still belong to this for range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual
In the range of type covers.
