Embodiment Construction

[0026] A composite wheel hub provided in this embodiment, such as Figure 1 to Figure 12 As shown, a web preform 8 and a rim preform 9 are included. Among them, the web preform consists of 4 to 6 groups of the same reinforced fiber material preforms that are staggered and stacked around the central axis of the hub to form spokes and a hub for connecting with the axle. In this embodiment, 5 groups are selected; From the outside to the inside, it includes the spoke surface layer 1, the material filling layer 2, the spoke back layer 3 and the hub reinforcement layer 4. The rim preforms also include 4 to 6 groups of the same reinforced fiber material preforms, and 5 groups are also used in this embodiment; each group of preforms is connected to two adjacent spokes at the same time, including the inter-spoke Connect the reinforcement layer 6 with the rim ring 7 .

Abstract

The invention relates to a composite material wheel hub, which includes a web preform and a rim preform. The web preform consists of 4 to 6 sets of the same reinforcing fiber material preforms stacked interlaced around the center axis of the hub to form a spoke and a wheel hub. At the hub connected to the axle, the rim preform includes 4 to 6 sets of identical reinforced fiber material preforms, and each set of preforms is connected to two adjacent spokes simultaneously. The invention makes the weight lighter while satisfying the performance of the hub; and further strengthens the integrity, safety and reliability of the spoke surface. Simultaneously, the invention is easy to scale production, ensures the quality consistency of the final product and reduces the manufacturing cost. The two-step curing process of pre-curing inside the mold and post-curing outside the mold is used to shorten the mold occupation cycle, which is beneficial to reduce the number of molds during large-scale production and increase the output per unit time.

Description

technical field [0001] The invention relates to an automobile wheel hub, specifically a reinforced fiber material preform structure suitable for manufacturing the wheel hub by a resin transfer molding process, and belongs to the technical field of automobile wheel hub manufacturing. Background technique [0002] With the increasing pressure of global environmental protection, governments of various countries have increasingly strict requirements on vehicle exhaust emissions. The automotive industry is committed to: 1. Reducing engine displacement, increasing power per liter, and improving fuel efficiency; 2. Developing hybrid or pure electric vehicles; 3. Replace the original materials with lighter and better materials to reduce the weight of the vehicle. No matter what kind of energy form the car, weight reduction is always an effective solution. [0003] As the main unsprung mass provider and important rotating part of the car, the lightweight of the wheel hub has an imme...
