Abstract
The utility model discloses a kind of spoke of heat emission hole with outer lug boss, spoke is connected to the one end of wheel rim axial direction, spoke is equipped with axle location hole, multiple bolts hole around the axle location hole annular array and multiple heat emission holes around the plurality of bolt hole annular array, it is characterised in that：The annular convex platform circumferentially extended along aperture is set on the outer aperture end face of each heat emission hole.The annular convex platform plays the role of strengthening heat emission hole periphery material intensity, avoid spoke and occur the phenomenon of stress concentration at heat emission hole again in stress, the strain speed of spoke is effectively slow down, prevents that heat emission hole periphery is cracked too early, extends the service life of spoke.
Description
Technical field
A kind of spoke of wheel is the utility model is related to, more particularly to a kind of spoke of heat emission hole with outer lug boss.
Background technology
Wheel generally includes tire, wheel rim, spoke and wheel hub, and tire is installed on wheel rim, and wheel hub is used for connecting with axle,
The effect of spoke is then connection wheel rim and wheel hub.Wheel is when being assembled on wheel hub, due to the high speed long time running meeting of wheel
Produce very high temperature；For this reason, the heat emission hole of circumference array need to be designed in spoke plane and end face junction.When spoke is installed on
During accumulation travels for a long time on traction engine, spoke heat emission hole is in more weak position, is easier appearance and strains very
To causing to rupture, shorten the service life of spoke.
One of conventional phenomenon of spoke strain rupture is to start to crack source around heat emission hole, along heat dissipation pore size distribution
Circular direction produces rupture, and main cause is that spoke is installed on wheel hub and is running over journey by bolt, nut check, vehicle
In often carry out brake emergency stop or traveling acted in the section of fluctuating, bolt torsion transmission around spoke heat emission hole, due to
Spoke heat emission hole periphery belongs to intensity compared with weak location, and discontinuity, fracture by fatigue is produced in the case where repeatedly stress acts on repeatedly
Phenomenon.
Utility model content
The utility model provides a kind of spoke of heat emission hole with outer lug boss, which overcomes present in background technology not
Foot.
Technical solution is used by the utility model solves its technical problem：
A kind of spoke of heat emission hole with outer lug boss, spoke are connected to the one end of wheel rim axial direction, and spoke is determined equipped with axle
Position hole, multiple bolts hole around the axle location hole annular array and multiple heat dissipations around the plurality of bolt hole annular array
Hole, the annular convex platform circumferentially extended along aperture is set on the outer aperture end face of each heat emission hole.
Among one embodiment：The annular convex platform has periphery wall and internal perisporium, and the corresponding internal diameter size of its internal perisporium is small
In or equal to heat emission hole internal diameter size.
Among one embodiment：The radial thickness of the annular convex platform is 1-4mm.
Among one embodiment：The radial width of the annular convex platform is 5-20mm.
Among one embodiment：The radial thickness of the annular convex platform is 1-2mm.
Among one embodiment：The radial width of the annular convex platform is 10-12mm.
Compared with background technology, it has the following advantages that the technical program：
The annular convex platform of spoke heat dissipation hole end surface plays the role of strengthening heat emission hole edged intensity；In spoke and wheel rim, wheel
After hub three connection, the bridge joint for playing the role of three at spoke heat emission hole transmits, and thickness and intensity belong to weakness herein
Position, after the annular convex platform by designing heat dissipation hole end surface is strengthened, the strength of materials of this weak location, which has, to be obviously improved, ring
Shape boss avoids spoke and occurs the phenomenon of stress concentration at heat emission hole in stress, have around the aperture periphery of heat emission hole
Effect slow down the strain speed of spoke, avoid cracked too early around heat emission hole, extend the service life of spoke.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 depicts spoke schematic perspective view of the spoke heat emission hole with annular convex platform.
Fig. 2 depicts spoke schematic front view of the spoke heat emission hole with annular convex platform.
Embodiment
Fig. 1 to Fig. 2, a kind of spoke of heat emission hole with outer lug boss are refer to, spoke 14 is connected to the axial one end of wheel rim 10
Portion, spoke 14 are equipped with axle location hole 141, multiple bolts hole 142 around 141 annular array of axle location hole and surround
Multiple heat emission holes 143 of the plurality of 142 annular array of bolt hole, set along aperture on the outer aperture end face of each heat emission hole 143
The annular convex platform 145 of circumferentially extending, the outer aperture end face are located on the convex surface of spoke, during wheels travel, outer aperture end face/spoke
Convex surface facing wheel/vehicle outside direction.
The annular convex platform 145 has periphery wall and internal perisporium, and the corresponding internal diameter size of its internal perisporium, which is less than or equal to, to be dissipated
The internal diameter size of hot hole.
The radial thickness of the annular convex platform 145 is 1-4mm, is preferably 1-2mm, which is the reality of annular convex platform
Body thickness, the radial width of the annular convex platform 145 is 5-20mm, is preferably 10-12mm, the radial width is outside annular convex platform
The diameter length of perisporium.
The above, is only the utility model preferred embodiment, therefore cannot limit the utility model implementation according to this
Scope, i.e., the equivalent changes and modifications made according to the utility model patent scope and description, it is new all should still to belong to this practicality
In the range of type covers.
