Description

Technical Field

[0001] The utility model relates to a lightweight wheel spoke. Background Art

[0002] The wheel spoke is a device that protects the rim and spokes of the vehicle wheel. It is characterized by a pair of circular cover plates. The diameter of the cover plates is close to the diameter of the wheel rim. There is a hole in the center of the cover plate that is larger than the rotation axis of the wheel. There is an opening near the edge of the cover plate. There is a ring wheel plate on the edge of the cover plate. The curved surface of the wheel plate can fit closely with the curved surface of the wheel rim. According to the structure of the spoke, it is divided into spoke plate type and spoke type. At present, the mainstream family cars all use the spoke plate type spoke structure. When driving at high speed for a long time, multi-spoke tires are generally used, which can provide good support and prevent the wheel from being greatly deformed during driving. In other words, the more spokes, the more stable, but wheels with fewer spokes also have their advantages. At least in terms of appearance, it has a unique sense of exposure. It is generally used on short-distance technical tracks and has the characteristics of light weight.

[0003] In the authorized Chinese utility model patent "Announcement No.: CN203920241U, Name: A Lightweight Truck Spoke", the notch groove is set at the connection between the spoke plate and the conical air hole surface, which will slightly reduce the connection strength to a certain extent. The connection strength is strengthened by strengthening the connecting strip, reducing the stress concentration at the connection between the spoke plate and the conical connecting surface, and improving the integrity of the wheel. However, it is difficult to effectively increase the structural strength of the spoke only by strengthening the connecting strip. In the above application, air holes are set to reduce weight, but the overall weight of the spoke is still large, resulting in more energy required during transportation or use, affecting the use of the spoke.
