Embodiment Construction

[0045] In the following description, the present invention will be described in detail based on exemplary embodiments.

[0046] The example of the present invention is based on a certain model of aluminum alloy wheel with a rim size of 14 x 5.5 inches and four bolt holes.

[0047] The present invention is a thermoplastic composite material wheel suitable for injection molding, the rim of which can be regarded as the composition of the rim base and the rim reinforcement structure, such as figure 1, the rim base 11 is similar to the rim of an aluminum alloy wheel, and the rim reinforcement structure 12 is attached to the rim base 11, and the outer profile formed by the two together meets the rim profile required by the national standard. To preserve the interior space of the rim, increase the rim diameter to 15 inches. The bead seats on both sides of the rim are in contact with the tire, which requires tightness, so the rim reinforcement structure 12 is designed in the middle a...

Abstract

The invention provides an injection-molded thermoplastic composite vehicle wheel. A rim of the vehicle wheel is composed of a rim base and a rim reinforcing structure. The rim base is similar to an aluminum alloy wheel rim. The rim reinforcing structure is attached to the rim base. An outer contour formed by the rim base and the rim reinforcing structure jointly can meet requirements. Bead seats on the two sides of the rim make contact with a tire. The rim reinforcing structure is designed to be located in the middle area between the two bead seats. The circumference of the rim reinforcing structure is divided into a plurality of areas. The included angle of each area is theta and corresponds to one draft direction passing through the center of the vehicle wheel, and the number of rim moulds can be changed by changing theta. The rim reinforcing structure is formed by a predetermined number of reinforcing units in a composite manufacturing mode. Each reinforcing unit is composed of two rib plates in a crossed X shape, and the intersection between the two rib plates is provided with a hollow cylinder for transition. The structure of the injection-molded thermoplastic composite vehicle wheel has a large rigidity mass ratio, so the thermoplastic composite vehicle wheel is designed to be a hollowed-out structural style, and the defect that thermoplastic composites are low in elasticity modulus is overcome.

Description

technical field [0001] The invention provides a thermoplastic composite material wheel suitable for injection molding, specifically relates to a structure of a thermoplastic composite material wheel suitable for injection molding, and belongs to the technical field of automobiles. technical background [0002] Lightweight structure is an important technical means to achieve energy saving and emission reduction of automobiles. The use of advanced composite materials to manufacture auto parts is one of the most important and effective means to achieve lightweight vehicles. Thermosetting composite materials have the advantages of high specific strength and high specific stiffness, and have been widely used in aerospace and other fields. However, due to their high price and low production efficiency, they have not been widely used in civilian automobiles in large quantities. Thermoplastic composites, such as long glass fiber-reinforced composites and carbon fiber-reinforced com...
