Automobile aluminum alloy hub

Abstract

The invention discloses an automobile aluminum alloy hub which comprises a hub body. The hub body comprises a wheel disc and a rim. The wheel disc comprises an inner disc and an outer disc. The innerdisc is arranged at the rear end of the outer disc. A shaft hole is formed in the center of the wheel disc. Multiple evenly-distributed main spokes are arranged on the periphery of the inner disc. Theother end of each main spoke is fixed to the rim. Multiple evenly-distributed auxiliary spokes are arranged on the periphery of the outer disc. The other end of each auxiliary spoke is fixed to the rim. The main spokes and the auxiliary spokes are arranged in a staggered mode. Multiple air guide cavities are formed between the main spokes and the auxiliary spokes. A protection device is arrangedat the front end of the hub body. The periphery of the rim is sleeved with a rim ring. The automobile aluminum alloy hub is simple in structure, reasonable in design and beautiful in appearance, the structural strength of the hub is guaranteed, the heat dissipation performance is good, the comfort level of a user in the traveling process is improved through the protection device and buffering devices, and the service life of the hub is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile aluminum alloy wheel hub. Background technique [0002] The hub, also known as the rim, is the barrel-shaped, center-mounted part of the tire that is used to support the tire. Common car wheels include steel wheels and aluminum alloy wheels. Steel wheels have high strength and are often used in large trucks; however, steel wheels are heavy and have a single shape, which does not conform to today's low-carbon and fashionable concepts, and is gradually being replaced by aluminum alloy wheels. The existing wheel hub does not have a suitable protective device. It is easy to be scratched by external factors when parking, and the tire will generate high temperature when the vehicle is running at high speed. If the heat dissipation condition of the wheel hub is not good, it will cause deformation and softening of the tire, which is not conducive to safe driving. ...

Steel wheels have high strength and are often used in large trucks; however, steel wheels are heavy and have a single shape, which does not conform to the current low-carbon and fashionable concept, and is gradually being replaced by aluminum alloy wheels

The existing wheel hub does not have a suitable protective device. It is easy to be scratched by external factors when parking, and the tire will generate high temperature when the vehicle is running at high speed. If the heat dissipation condition of the wheel hub is not good, it will cause deformation and softening of the tire, which is not conducive to safe driving.
