Embodiment 2

[0036] Such as Figure 6-7 As shown, the structure, principle and implementation steps of this embodiment are similar to those of Embodiment 1, the difference is that the spokes 3 in this embodiment are made of aluminum alloy and are connected with the inner layer 4 of the rim 1 and the axle mounting seat 2. In one piece, the spokes 3 are arranged symmetrically with respect to the center of the axle mount 2 , and honeycomb-shaped through holes 31 are distributed on the spokes 3 . Aluminum alloy spokes 3, axle mounts 2 and the inner layer 4 of the rim 1 are used as the basic skeleton, and the outer layer 5 of the rim 1 is still made of carbon fiber composite material, which further reduces the production cost, and adopts a honeycomb structure to greatly reduce the weight of the rim 1 Weight, to meet the lightweight requirements of the wheel hub.

[0037] To sum up, the principle of this embodiment is that the sheet-like spokes 3 facilitate the processing and molding of carbon ...

Abstract

The invention provides a light carbon fiber composite material hub, and solves the problems of high production cost and the like of a carbon fiber hub. The hub comprises a rim and an axle mounting seat, the rim and the axle mounting seat are connected through a plurality of spokes which are symmetrical relative to the central axis of the rim and the axle mounting seat; the spoke is in a sheet shape, the width of the end, close to the rim, of the spoke is larger than the width of the end, close to the axle mounting base, of the spoke, the spoke or the multiple spokes are arranged at intervals in the circumferential direction, and the rim is provided with an inner layer made of aluminum alloy and an outer layer made of carbon fiber composite materials, and the inner layer is coated with the outer layer. The hub has the advantages of low production cost, high structural strength and the like.

Description

technical field [0001] The invention belongs to the technical field of wheel hubs, and in particular relates to a lightweight carbon fiber composite material wheel hub. Background technique [0002] The wheel hub is the rotating part of the wheel core connected by the inner profile of the tire through the column, that is, the metal part that supports the center of the tire and is mounted on the shaft. Also known as rims, steel rims, wheels, and tire bells. In the past, most car wheel bearings used single-row tapered roller or ball bearings in pairs. With the development of technology, cars have widely used car hub units. The use range and amount of hub bearing units are increasing day by day, and it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply fit the bearing on the wheel shaft and fix it with nuts. Makes car ...
