Wheel hub with hollow structure as well as motor vehicle

Abstract

The invention provides a wheel hub with a hollow structure. The wheel hub with the hollow structure comprises a rim, a plurality of spokes and an installation disc; one ends of the spokes are fixedly connected with the rim, and the other ends of the spokes are fixedly connected with the installation disc, and the plurality of spokes are uniformly distributed between the rim and the installation disc; the wheel hub is provided with a hollow structure; the hollow structure comprises a first part in a rim wall and a second part in spoke bodies; the first part and the second part are mutually communicated, and extend to the installation disc; one end of the hollow structure, which is positioned in the spokes, is sealed, and the other end of the hollow structure, which is positioned in a rim wall, is provided with an opening, and the opening is positioned on the inner wall surface of the rim; the inner wall surface of the rim is used for installing a vacuum tyre. The invention also provides an engine vehicle. A heat dissipation area of the wheel hub is increased for an empty cavity of the wheel hub provided with the empty cavity provided by the invention, and the integral weight of the wheel hub is lowered; the empty cavity and the inner part of the vacuum tyre are communicated, so that the intensity of pressure in the empty cavity and the intensity of pressure in the vacuum tyre are equal, and further the wheel hub has greater intensity; the safety of the wheel hub cannot be lowered under the condition of reducing the weight of the wheel hub.

Description

technical field [0001] The invention relates to a hub, in particular to a hub with a hollow structure and a motor vehicle comprising the hub. Background technique [0002] With the increasing requirements for energy saving and consumption reduction of modern motor vehicles, safety and environmental protection regulations are becoming increasingly stringent, and the requirements for lightweight motor vehicles are more urgent. As a product to reduce the weight of motor vehicles, the lightweight and high strength of aluminum alloy wheels has become the core of competition in the wheel industry with the in-depth development of the motor vehicle industry. All wheel hub manufacturers are constantly looking for the ultimate lightweight technology. Enable new products to occupy a leading position in the market competition. [0003] At present, many wheel hub manufacturers have installed hollow structures in the spokes, but in order to ensure the high strength of the hubs, the hollo...

AI Technical Summary

Problems solved by technology

[0003] At present, many wheel hub manufacturers have installed hollow structures in the spokes, but in order to ensure the high strength of the hubs, the hollow structures should not be too large, and the weight of the hubs should not be reduced too much, or the spokes have larger hollow structures. , although the weight of the wheel hub is reduced, the strength of the wheel hub is difficult to meet the technical requirements and cannot be put into production, and the heat dissipation effect of the wheel hub in the prior art is not good. The aging speed reduces the service life of the hub
