Abstract

The utility model discloses a kind of spoke of split structure, spoke is connected to the one end of wheel rim axial direction, and spoke is equipped with center positioning hole, multiple bolts hole around the center positioning hole annular array；The distribution circle of the spoke along bolt hole opens up fracture gap so that spoke is broken to form separable first split and the second split, the center positioning hole is located in the second split, the gap width in the fracture gap is uniform, and the fracture gap forms convex arc section along the extension of distribution circle and towards the outer protrusion of distribution circle between bolt hole adjacent two-by-two.The spoke of the structure has saved the function of spoke from damage and spoke can be made effectively to be slowed down the strain speed of spoke by the phenomenon that rupturing is reduced during bolt torsion, extend the service life of spoke, so as to also extend the service life of wheel.

Description

A kind of spoke of split structure

Technical field

The utility model is related to a kind of wheel spoke, more particularly to a kind of spoke of split structure.

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, and by multiple bolts by spoke fit in wheel hub plane locking carry.

The conventional phenomenon of spoke strain rupture is that the position more weak on bolt hole periphery starts to crack or multiple The crack phenomenon of crackle generates rupture along bolthole circle direction or even is present with whole using bolt hole as line of demarcation rupture Phenomenon, main cause are that spoke is installed on wheel hub and carries out nut check, and vehicle is often stopped in the process of moving Vehicle emergency stop is travelled in the section of fluctuating, and the transmission of bolt torsion is acted on around spokes plane, due to spokes Position belongs to intensity compared with weak location, directly acts on stress and uneven, is repeatedly generating fracture by fatigue under stress effect repeatedly Phenomenon.

Utility model content

The utility model provides a kind of spoke of split structure, which overcomes the deficiency present in background technology.

Technical solution is used by the utility model solves its technical problem：

A kind of spoke of split structure, spoke are connected to the one end of wheel rim axial direction, spoke be equipped with center positioning hole, Around multiple bolts hole of the center positioning hole annular array；The distribution circle of the spoke along bolt hole opens up fracture gap to incite somebody to action Spoke breaks to form separable first split and the second split, and the center positioning hole is located in the second split, the fracture The gap width in gap is uniform, and the fracture gap extends along distribution circle and between bolt hole adjacent two-by-two towards distribution circle Outer protrusion forms convex arc section.

Among one embodiment：The gap width in the fracture gap is 0.1-2.0mm.

Among one embodiment：The gap width in the fracture gap is 1mm.

Among one embodiment：The radius of the convex arc section is 8-15mm, and the chord length corresponding to the convex arc section both ends is 15- 30mm。

Among one embodiment：The radius of the radian of the convex arc section is 10mm, and the chord length corresponding to the convex arc section both ends is 20mm。

Compared with background technology, it has the following advantages that the technical program：

Multiple bolts corresponding to the spoke in same plane while stress and are acted in two splits, have saved spoke from damage Function；In vehicle travels loading procedure, generate regular shake, emergency stop, jolt, spoke is at the reference circle of bolt hole If fracture gap, the phenomenon that by bolt torsion when can reduce rupture, the strain speed of spoke is effectively slowed down, extends 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 of wheel split structure.

Fig. 2 depicts a kind of schematic front view of the spoke of wheel split structure.

Specific embodiment

Fig. 1 to Fig. 2, a kind of spoke of split structure are refer to, spoke 11 is connected to the axial one end of wheel rim 10, wheel Spoke 11 is equipped with center positioning hole 14, multiple bolts hole 13 around 14 annular array of center positioning hole；11 edge of spoke The distribution circle of bolt hole 13 opens up fracture gap 12 so that spoke 11 is broken to form separable first split, 111 and second split 112, the center positioning hole 14 is located in the second split 112, and 13 1 half part of bolt hole is located in the first split 111, Another half part is located in the second split 112, and the gap width in the fracture gap 12 is uniform, and the gap 12 that is broken is along distribution Circle extension simultaneously forms convex arc section 121 between bolt hole 13 adjacent two-by-two towards the outer protrusion of distribution circle, i.e., except the convex arc section 121 Fracture gap in addition is overlapped with the distribution of bolt hole 13 circle.

It is described fracture gap 12 gap width be 0.1-2.0mm, it is preferred that it is described fracture gap 12 gap width be 1mm。

The radius of the convex arc section is 8-15mm, and the chord length corresponding to the convex arc section both ends is 15-30mm, it is preferred that institute The radius of the radian of convex arc section is stated as 10mm, the chord length corresponding to the convex arc section both ends is 20mm.

The above is only the utility model preferred embodiment, therefore cannot limit the utility model implementation according to this It is new all should still to belong to this practicality for scope, i.e., the equivalent changes and modifications made according to the utility model patent scope and description In the range of type covers.
