Carbon fiber wheel hub

Abstract

The invention discloses a carbon fiber wheel hub. The carbon fiber wheel hub comprises a rim and a spoke which are each made of a carbon fiber material. The connecting positions of the rim and the spoke adopt metal structures for connection, a plurality of reserved assembly holes are formed in the rim and the spoke when the rim and the spoke are formed, and each reserved assembly hole and a metal piece with an assembly hole are fixed together. A reserved central hole is formed in the center of the spoke and internally matched with a metal assembly ring with a shaft hole, and a plurality of locking holes matched with a wheel shaft hub body for lock fixing are further formed in the position, on the external circle of the reserved central hole, of the spoke. A metal ring is fixed into each locking hole, and a metal piece corresponding to a wheel hub bearing is further fixed to the face, facing the wheel shaft hub body, of a spoke body. The carbon fiber wheel hub is small in weight, better in impact resistance and thus safer; the damping effect is good, and the comfort degree is increased; and the mass is smaller, inertial resistance is small, and while manipulating performance of a car can be better improved, and oil consumption is reduced.

Description

technical field [0001] The invention relates to an automobile hub, in particular to a carbon fiber automobile hub. 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 and practical life. At p...

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
