Description

Spoke

Technical Field

The utility model discloses a spoke for wheelset, aforementioned wheelset can be used to car, motorcycle, bicycle.

Background

The wheel set is a member for contacting the vehicle with the ground, and is an important and indispensable part for the vehicle to run besides the supporting function of the whole weight of the vehicle. The wheel set is of a steel wire ring (frame) type and mainly comprises a hub, a rim and a spoke assembly, wherein the spoke is made of metal, and two ends of the spoke are respectively connected with the hub at the central position and the rim at the peripheral position.

As shown in fig. 9 and 10, in fact, the spokes are in a tensioned state, and mainly one end of the spokes 71 is designed to be in a conical inverted hook shape and is buckled on the hub 72, and the other end is designed to be provided with an external thread section 73 and is penetrated through the inner side surface of the rim 74, and then is screwed by a special joint 76(spoke nipple), and is locked by a tool 75, and the joint 76 is tightly pressed to a preset hole of the rim 74, so that the spokes 1 are tightened. After the assembly is completed, it is necessary to detect whether the wheelset is running with a yaw, a true circle, a spoke tension, etc., and to unscrew or tighten the joint 76 at the corresponding position. The wheelsets accumulate long riding distances or on a bumpy road surface, which can cause the wheelsets to deflect, and the wheelsets also need to be detected.

In the operation of the tightening joint 76, the threaded engagement between the female threaded hole of the joint 76 and the male threaded section 73 causes a force to pull the spoke 71 and increase the tension (as indicated by the linear arrow), and the joint 76 also causes a torsional force (as indicated by the rotational arrow) to the position of the male threaded section 73 of the spoke 71. However, the action of screwing the joint 76 causes stress concentration at the spot where the spoke 71 is screwed, so that the structural strength is weak, especially the locking torque exceeds the range that the spoke 71 can bear when screwing the joint 76, and the spoke is easy to break.

Detailed Description

Referring to fig. 1 and 2, a spoke 1 is disclosed, which includes a first portion 2, a second portion 3, and a third portion 4 movably assembled with the first portion 2 and the second portion 3; a first threaded hole 41 and a second threaded hole 42 are respectively formed at two ends of the third portion 4, the first portion 2 has a first threaded section 21 screwed in the first threaded hole 41, and the second portion 3 has a second threaded section 31 screwed in the second threaded hole 42.

Referring to fig. 3 to 5, the first portion 2 of the spoke 1 is movably connected to the rim 6, and the second portion 3 of the spoke 1 is movably connected to the rim 5, by rotating the third portion 4 such that the third portion 4 rotates radially (as indicated by the rotating arrow), the first threaded hole 41 screwed to the first threaded section 21 and the second threaded hole 42 screwed to the second threaded section 31 are made to allow the third portion 4 to pull the first portion 2 and the second portion 3 toward the third portion 4, respectively, so as to deform the first portion 2 and the second portion 3 in the axial direction thereof (as indicated by the linear arrow) and tighten the hub 5 and the rim 6.

Further, the detailed features and the technical features of mutual combination of the components of the present invention will be described in detail. Wherein the first portion 2 is movably assembled with the rim 6 at one end thereof and is provided with a driving recess 22 for a tool to rotate the first portion 2. The outer periphery of the second portion 3 is provided with a plurality of adjustment planes 32 along the outer surface thereof, and the adjustment planes 32 are close to the direction of assembling the second portion 3 to the hub 5. In addition to the rotation of the third portion 4 to tighten the hub 5 and the rim 6 by the first portion 2 and the second portion 3, the present invention can also rotate the first portion 2 independently through the driving groove 22 of the first portion 2 (as shown in fig. 6) by using a tool, and the rim 6 is pulled by the first portion 2 toward the hub 5, so as to achieve the effect of the spoke 1 to tighten the hub 5 and the rim 6; alternatively, the adjustment plane 32 can be pressed by a tool and the second portion 3 can be rotated to pull the hub 5 from the second portion 3 toward the rim 6 (as shown in FIG. 7), which also achieves the effect of the spoke 1 tightening the hub 5 and the rim 6.
