Abstract
The utility model discloses a kind of spokes with strengthening rib strip, spoke is connected to the one end of wheel rim axial direction, spoke is equipped with center positioning hole, multiple bolts hole of the circular center positioning hole annular array and multiple heat emission holes around multiple bolt hole annular array, tangent connection between the spoke cambered surface part where spoke planar section and heat emission hole where bolt hole；From the tangency location of the planar section and cambered surface part to the spoke body part heat emission hole lower edge, along spoke circumferential direction and be positioned apart from several strengthening rib strips, moment stress concentration when jolting, shaking road surface or heavy duty zig zag is driven to vehicle and plays the role of buffering, prevent spoke plane from generating crack damage with the strength weak position at heat emission hole, effectively slow down the strain speed of spoke, the service life of spoke is extended, so as to also extend the service life of wheel.
Description
Technical field
The utility model is related to a kind of wheel spoke, more particularly to a kind of spoke with strengthening rib strip.
Background technology
Wheel generally includes tire, wheel rim, spoke and wheel hub, and tire is mounted 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 mainly positioned at wheel hub on wheel hub is assembled to by center positioning hole
On, the plane locking that spoke is fitted in wheel hub by multiple bolts carries.
Spoke is equipped with center positioning hole, around multiple bolts hole of the center positioning hole annular array and around multiple
Multiple heat emission holes of bolt hole annular array, spoke body part wherein where bolt hole are a plane, where heat emission hole
Spoke body part be a cambered surface, tangent connection between the plane and cambered surface.
One of conventional phenomenon of spoke strain rupture is started in the more weak position of the joining place of the plane and cambered surface
The cracking of plastic deformation or multiple crackles is generated, torsional deformation is generated along spoke direction of rotation or even will appear with plane, arc
Whole rupture of the face points of tangency for line of demarcation, main cause is that spoke is installed on wheel hub and carries out nut check, and vehicle exists
Brake emergency stop or traveling are often carried out in driving process in the section of fluctuating, the transmission of bolt torsion acts on plane and cambered surface
Around tangent, since plane and cambered surface tangency location belong to intensity compared with weak location, directly effect stress and discontinuity,
Repeatedly stress effect lower spokes generate plastic deformation or fracture by fatigue phenomenon repeatedly.
Utility model content
The utility model provides a kind of spoke with strengthening rib strip, and which overcome the deficiencies present in background technology.
Technical solution is used by the utility model solves its technical problem：
A kind of spoke with strengthening rib strip, spoke are connected to the one end of wheel rim axial direction, spoke be equipped with center positioning hole,
Multiple bolts hole around the center positioning hole annular array and multiple heat emission holes around multiple bolt hole annular array, spiral shell
Tangent connection between the spoke cambered surface part where spoke planar section and heat emission hole where keyhole；From the planar section and arc
The tangency location of face part to the spoke body part between heat emission hole lower edge, along spoke circumferential direction and be positioned apart from several
Strengthening rib strip.
Among one embodiment：Several strengthening rib strips are along the equally circumferentially spaced of spoke.
Among one embodiment：The quantity of the strengthening rib strip is 10-30.
Among one embodiment：The quantity of the strengthening rib strip is 10.
Among one embodiment：The radical length of the strengthening rib strip along spoke is 3-10mm, circumferential width 1-5mm.
Among one embodiment：The radical length of the strengthening rib strip is 6mm, circumferential width 3mm.
Compared with background technology, it has the following advantages that the technical program：
Pass through the tangency location from the planar section and cambered surface part to the spoke body part heat emission hole lower edge, edge
The circumferential direction of spoke and be positioned apart from several strengthening rib strips, make spoke body part where bolt hole with where heat emission hole
Weak location intensity between spoke body part increases, and vehicle is driven to and jolts, shake road surface or when heavy duty is taken a sudden turn
Moment stress concentration plays the role of buffering, prevents the spoke body part where bolt hole and the spoke ontology where heat emission hole
Strength weak position between part generates crack damage, effectively slows down the strain speed of spoke, extends the use of spoke
Service life, so as to also extend the service life of wheel.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 depicts a kind of stereoscopic schematic diagram of the spoke with strengthening rib strip.
Fig. 2 depicts a kind of schematic front view of the spoke with strengthening rib strip.
Specific embodiment
Fig. 1 to Fig. 2, a kind of spoke with strengthening rib strip are please referred to, spoke 11 is connected to the axial one end of wheel rim 10, wheel
Spoke 11 is equipped with center positioning hole, around multiple bolts hole 13 of the center positioning hole annular array and around multiple bolt
Multiple heat emission holes 14 of 13 annular array of hole, spoke of the spoke planar section 111 where with heat emission hole 14 where bolt hole 13
Tangent connection between cambered surface part 112；From the tangency location of the planar section 111 Yu cambered surface part 112 to 14 lower edge of heat emission hole
Between spoke body part, along spoke circumferential direction and be positioned apart from several strengthening rib strips 12.
The quantity of several strengthening rib strips 12 along the equally circumferentially spaced and described strengthening rib strip 12 of spoke 11 is 10-
30, it is preferred that the quantity of the strengthening rib strip 12 is 10.
The radical length of the strengthening rib strip 12 is 3-10mm, circumferential width 1-5mm, it is preferred that the strengthening rib strip
12 radical length is 6mm, circumferential width 3mm.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited according to this
It is new all should still to belong to this practicality for range, i.e., the equivalent changes and modifications made according to the utility model patent range and description
In the range of type covers.
