Abstract

The invention discloses a lightweight truck aluminum hub which comprises a shaft sleeve; the periphery of the outer wall of the shaft sleeve is fixed to a positioning seat on the inner wall of a rim through spokes; the five spokes are distributed in a five-pointed-star shape; each spoke comprises a lower base, a telescopic assembly, a first supporting spring and an upper base; and the lower basesare fixed to the periphery of the outer wall of the shaft sleeve. An upper base is fixed to the top of each lower base through two telescopic assemblies, the two telescopic assemblies are distributedin an inverted-V shape, the upper base is fixed to a positioning base, and the telescopic assemblies are sleeved with first supporting springs located between each lower base and the corresponding upper base. The hub is novel in structure and ingenious in conception, noise generated in the vehicle driving process can be reduced, the elastic buffering function is achieved, the structural strength of the rim is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of wheel hubs, in particular to a lightweight truck aluminum wheel hub. Background technique [0002] The lightweight of the car is to reduce the curb weight of the car as much as possible under the premise of ensuring the strength and safety performance of the car, so as to improve the power of the car, reduce fuel consumption, and reduce exhaust pollution. In the development process of the truck market in recent years, as the country has become more and more strict on overloading and exceeding the limit, users are more and more inclined to lightweight products, and users' requirements for purchased vehicles have also undergone great changes. . 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. Th...
