Description

Spoke and wheel

Technical Field

The present invention relates to vehicle wheel structures, and more particularly to a wheel spoke and wheel.

Background

A wheel generally comprises 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, the cracking phenomenon begins to be generated at the positions of the radiating holes with the weakest strength under the repeated stress action for many times, meanwhile, the vehicle is braked and operated when a braking system is in high-speed running at variable time, continuous high-load operation is carried out during heavy load, and the brake pad is directly transmitted to the rim and the tire due to high-temperature heat generated by friction, so that the damage frequency of the weak points of the rim is accelerated.

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.

The spoke is the main stressed element for ensuring the wheel to bear the supporting load and transmit the torque. The tire and ground friction and brake drum all can produce very high heat when the vehicle is traveling, consequently not only require highly to the ventilation capacity of wheel spoke, if can drive the heat dissipation gas through the rotation of wheel, the effect is better.

In practical situations, in order to enhance the ventilation capacity of the vehicle running wheel in the actual use process, a plurality of heat dissipation holes (also called air holes) are formed in the conical cylinder of the spoke, but the spoke structure only provided with the air holes can only meet the ventilation requirement of the wheel and cannot meet the requirement of dissipating hot air, and the damage phenomena of high temperature of a brake hub and the wheel, brake failure and tire burning often occur in the use process.

Referring to fig. 1 to 3, a spoke 10 is a truncated cone cylinder, and a plurality of heat dissipation holes 111 are uniformly distributed on a cylinder wall 11 of the truncated cone cylinder at intervals around the circumference thereof.

The cylindrical wall between at least two pairs of adjacent heat dissipation holes 111 is integrally formed with a circular cylindrical heat dissipation groove 112 protruding towards the outer surface of the cylindrical wall, the central axis of the cylinder of the heat dissipation groove 112 forms an included angle with the circumferential direction of the cylindrical wall 11, one end of the circular cylindrical shape of the heat dissipation groove 112 is an open notch 1121, the notch 1121 of the heat dissipation groove 112 is connected with the hole edge of the adjacent heat dissipation hole 111 and is communicated with the heat dissipation hole 111, namely, one axial end of the heat dissipation groove 112 is intersected with the cylindrical wall 11, and the other end is the end where the notch 1121 communicated with the heat dissipation hole 111 is located and protrudes out of the cylindrical wall 11.

The notches 1121 of some of the heat dissipating grooves 112 face the circumferential front of the spokes, and the notches 1121 of the remaining heat dissipating grooves face the circumferential rear of the cylindrical wall 11. In this embodiment, an orthogonal projection of the central cylindrical axis of the heat dissipation grooves 112 on the cylindrical wall 11 is tangential to the circumferential direction of the cylindrical wall 11, so that the notches 1121 of the heat dissipation grooves 112 described in this embodiment specifically face the tangential direction of the circumferential direction of the cylindrical wall 11 (i.e., directly in front of or directly behind the circumferential direction). In other embodiments, the orthographic projection of the central cylindrical axis of the heat dissipation grooves 112 on the cylinder wall 11 may intersect with the circumferential direction of the cylinder wall 11, and the notches 1121 of the heat dissipation grooves 112 face obliquely forward or obliquely backward of the circumferential direction of the cylinder wall 11, so long as the heat dissipation grooves 112 form a rib structure to enhance the airflow and guide the airflow into the hub for heat dissipation.
