Description

Spoke and wheel

Technical Field

The invention relates to the field of vehicles, in particular to a spoke and a wheel.

Background

Automotive wheels generally comprise a tyre mounted on a rim, a rim intended to be connected to an axle, spokes intended to connect the rim to the hub, and a hub. The traditional wheel is formed by welding a single spoke and a single rim, the vehicle can be braked and suddenly stopped frequently in the long-time running process or runs on an undulating road section, alternating stress borne by the tire directly acts on the rim, the alternating stress is transmitted to the radiating holes of the spoke through the rim, and the phenomenon of cracking begins to occur at the position of the radiating hole with the weakest strength under the repeated stress action for many times.

The traditional heat dissipation hole is a round through hole with a large area. The conventional phenomenon of louvre damage is that the biggest point of louvre atress begins to produce the crackle source, produces along the circumferencial direction and breaks, and the main reason is that the spoke is installed on wheel hub and is carried out nut locking, and the vehicle often can brake scram or go at the highway section of undulation in the long-time driving process, and bolt torsion direct action is at the spoke, transmits torsion to louvre department through the spoke. When a vehicle bears, force from the ground directly acts on the tire, the force is transmitted to the rim through the tire, alternating stress generated by the spoke borne by the wheel is collected at the radiating hole, and the fatigue fracture phenomenon starts to be generated at the position of the radiating hole with the weakest strength under the repeated stress action for many times.

Disclosure of Invention

The technical scheme adopted by the invention for solving the technical problems is as follows:

the utility model provides a spoke, it is including the heat radiation structure who encircles spoke center gyration axis and evenly space the setting, heat radiation structure is including being the spoke body between a plurality of louvres and each louvre that the gathering distributes, is separated by the spoke body between each louvre.

In one embodiment: the plurality of radiating holes of each radiating structure are positioned in the same circle, and the radiating holes at the outermost periphery are internally tangent to the circle.

In one embodiment: the spoke bodies among the heat dissipation holes of each heat dissipation structure form Chinese characters or letters or the shape of combination of the Chinese characters and the letters.

In one embodiment: the Chinese characters are 'positive' characters or 'xing' characters.

In one embodiment: the plurality of heat dissipation holes of each heat dissipation structure and the spoke bodies among the heat dissipation holes form a set mark pattern.

In one embodiment: the heat dissipation structure is provided with an annular flat plate and a rotary conical wall, one end of the rotary conical wall is connected with the outer periphery of the annular flat plate, and the heat dissipation structure is arranged on the rotary conical wall.

In one embodiment: and a plurality of bolt holes are uniformly arranged on the annular flat plate at intervals around the central revolution axis of the spoke.

A wheel comprises the spoke and the rim, wherein the spoke is connected to one end of the rim in the axial direction of a central rotating shaft.

Compared with the background technology, the technical scheme has the following advantages:

through the louvre improvement cost scheme with the great round hole form of area that will have now be a plurality of louvres that the gathering distributes and be located the spoke body between each louvre, the spoke body between each louvre has the effect of the strengthening rib of strengthening louvre department intensity this moment, when the alternating stress that the rim received acts on the spoke, this strengthening rib can undertake partly bearing capacity, be difficult for causing the wheel to appear torsion too big and the phenomenon that the louvre breaks or damages under the circumstances that the vehicle heavily loaded or the road conditions of traveling are not good, the strain speed of spoke has effectively been slowed down simultaneously, the weight that whole car can bear has been increased, the life of wheel has been prolonged.
