Problems solved by technology

[0003] The reality is that in the actual use process, due to the need for heat dissipation of the vehicle running wheels, heat dissipation holes (also called wind holes) must be made at the spoke cones. There must be a weakening of strength here, and cracking is often relatively difficult from here during use. More, shorter wheel life

Embodiment 1

[0025] Such as figure 1 As shown, the spoke structure of the present invention is in the shape of a truncated cone. The lower bottom of the conical frustum at the larger end of the conical barrel body 20 is open, and the upper bottom of the conical frustum at the smaller diameter end is an annular mounting plane 10, and bolt holes 11 are evenly distributed on the annular mounting plane 10 for the overall mounting of the wheel. Fixed, the center of the annular mounting plane 10 is the axle positioning hole 12 . Radiating holes 21 are evenly distributed on the conical barrel body 20 of the frustum-conical cylindrical outline of the spokes, and the cooling holes 21 are through holes, and the number and size of the cooling holes 21 can vary. The design of the cooling holes 21 can not only reduce the weight of the spokes, but also play a role in cooling the spokes. The cooling holes 21 may be circular holes, elliptical holes or through holes of other shapes. As a preferred embod...

Embodiment 2

[0029] Such as figure 2 As shown, in this embodiment, the boss 30 is disposed on the outer wall 23 of the tapered barrel 20 . The boss 30 extends from the installation plane 10 toward the opening of the tapered barrel 20 and covers the surroundings of the cooling holes 21 . The boss 30 has a strip structure, and the two sides of the boss 30 are respectively connected with the installation plane 10 and the tapered barrel 20 with open openings.

[0030] Other parts are identical with embodiment 1.

Embodiment 3

[0032] In this embodiment, both the inner wall 22 and the outer wall 23 of the tapered barrel 20 are provided with bosses 30 .

[0033] Other parts are identical with embodiment 1, embodiment 2.

Abstract

The invention relates to a light-weight wheel spoke for automobiles. By thickening the material around the heat dissipation holes on the inner wall of the spoke, the strength around the heat dissipation holes is improved, thereby increasing the overall service life of the wheel spokes. The thinning of the material between the heat dissipation holes (that is, the place where there are no heat dissipation holes on the tapered barrel) makes the tapered barrel of the spoke form a unique concave-convex structure design on the inner wall or outer wall, so that the entire spoke can ensure the load bearing of the wheel Under the premise that the force is not affected, not only the overall strength of the spokes is improved, but also the amount of material used to make the spokes is reasonably and effectively used to reduce the weight of the spokes, thereby reducing the weight of the vehicle and reducing fuel consumption. Based on the detection data, the invention can effectively improve the fatigue strength and achieve the purpose of prolonging the service life of the spokes. The invention is applicable to large vehicles such as trucks and passenger cars, and is a new innovative improvement made to the wheel spokes of existing automobiles.

Description

technical field [0001] The invention relates to a wheel spoke for automobiles, more specifically, to a thickened wheel spoke around a cooling hole. Background technique [0002] The wheel is a support that transmits the force of the vehicle body and the road surface when the vehicle is walking. It is equivalent to the foot of the vehicle and generally consists of a rim and spokes. The rim and the spokes are assembled together by welding, the tires are installed on the outside of the rim, and the spokes have mounting holes to connect with the axle. Spokes are the main force-bearing parts to ensure that the wheels bear the supporting load and transmit torque, especially for large vehicles such as trucks and buses, which have higher requirements for the bearing capacity and safety of the wheel spokes. [0003] The reality is that in the actual use process, due to the need for heat dissipation of the wheels of the vehicle, cooling holes (also called air holes) must be made at t...
