Carbon fiber hub spoke

Abstract

The invention discloses a carbon fiber hub spoke which is provided with a spoke body. The spoke body is made from a carbon fiber material and provided with a plurality of reserved assembly holes locked to a rim. Each reserved assembly hole is internally provided with a metal piece provided with an assembly hole. The center of the spoke body is provided with a reserved central hole matched with a wheel shaft hub. The reserved central hole is internally provided with a metal assembly ring in a matched mode. A plurality of locking holes locked to the wheel shaft hub in a matched mode are further formed in the portion, on the outer circle of the preserved central hole, of the spoke body. A metal ring is fixed into each reserved locking hole. A metal piece corresponding to a hub bearing is further fixed to the face, facing the wheel shaft hub, of the spoke body. According to the carbon fiber hub spoke, after the spoke and the rim are combined into a hub, the hub is low in weight and better in collision resistance, so that the hub is safer; and the carbon fiber hub spoke is good in damping effect, improves comfort and is lower in weight, small in inertial resistance and capable of better reducing oil consumption while improving control performance of an automobile.

Description

technical field [0001] The invention relates to an automobile tire component, in particular to a carbon fiber automobile wheel hub spoke. Background technique [0002] After decades of development, my country's automobile industry has become an important industry in the national economy. With the advancement of technology and the improvement of various performance indicators of automobiles, governments around the world have increasingly stringent requirements for energy conservation and environmental protection. Therefore, the lightweight of automobiles has become the main direction of automobile development. A 1% reduction in the weight of general automobile parts can save 1% of fuel, and every 1% reduction in the weight of moving parts can save 2% of fuel. [0003] Automobile hub is a component installed on the automobile to support the tire. As one of the most important moving parts of the automobile, the automobile hub has high requirements on its performance, weight an...

Problems solved by technology

[0004] The manufacture of carbon fiber wheels is based on mold sub-forming or material pre-forming technology, and the thickness of the product after the mold is partially uneven; in order to preserve the fiber integrity of carbon fiber, the uneven thickness cannot be refined and smoothed by machining like metal materials. Then it will lead to the balance problem of the installation of the wheel hub, which will affect the driving. At the same time, the hub made of carbon fiber is installed on the hub bearing of the car, and it needs to be installed repeatedly. If it is carbon fiber composite material, the installation screw hole will be worn and cause The balance problem of the installation affects driving and safety; in addition, the two-piece carbon fiber car hub needs to be locked firmly at the locking place of the rim and spoke screws. If the screws are removed, the carbon fiber screw holes will be worn and locked again. When the lock is not met, it will affect the driving safety of the car

Therefore, if there is a problem with the existing carbon fiber hub after assembly, the entire hub needs to be replaced, which is costly and brings troubles to actual use
