Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as Figure 1-2 As shown, the present invention is an improved split wheel, including an aluminum alloy wheel disc 1, a composite material rim 2, and a metal fastening ring 3.

[0022] In order to increase the contact area and improve the fastening reliability, a metal fastening ring 3 is installed at the connection part of the composite material rim 2, and the aluminum alloy wheel disc 1, the composite material rim 2 and the metal fastening ring 3 are connected together by bolts or rivets. The metal fastening ring 3 is reinforced in the form of right-angle wrapping.

[0023] In order to limit the weight gain, the through-holes of the metal fastening ring 3 are evenly arranged.

[0024] Meanwhile, other experimental parameters were as follows:

Abstract

The invention provides a split wheel. The split wheel comprises a turntable part 1, a rim part 2 and a metal fastening ring 3, wherein the turntable part 1 is made of an aluminum alloy; the metal fastening ring 3 is made from 65Mn steel; the rim part 2 is made from a carbon fiber composite material; the rim part 2 and the metal fastening ring 3 are fixed to the turntable part 1 through a bolt or a rivet together. The technical scheme provided by the invention has the following advantages that the contact area of the place where the rivet or the nut and a composite material rim are connected is effectively increased by the metal fastening ring, fastening force is dispersed and is more uniform; under the action of the metal fastening ring, the pre-tightening torque can be increased. The problems that the tightening torque is reduced and the wheel fails are effectively solved.

Description

technical field [0001] The invention relates to a wheel for automobiles, especially a split wheel. Background technique [0002] In the automotive industry, it is desirable to reduce the weight of components such as vehicle wheels as much as possible. On the basis of maintaining the original mechanical strength, if the weight of the car wheel can be reduced, it will be able to improve the handling performance of the car and save fuel, resulting in good economic and social benefits. [0003] To meet this need, there are two approaches. For one-piece wheels, the material of the wheel is typically replaced with a less dense alloy, such as magnesium alloy. For split wheels, the less stressed parts of the wheel are generally replaced with less dense materials. For example, replacing the rim part with a less dense metal alloy or composite material. [0004] Split wheels can meet a variety of complex working conditions, and can use targeted designs and materials for different c...
