Problems solved by technology
[0006] In order to make up for the deficiencies in the prior art, the invention proposes a lightweight aluminum alloy wheel hub. The invention is mainly used to solve the existing hollow shape formed by a plurality of support columns evenly arranged on the hub body. When the wheel hub travels to On roads with potholes and lots of gravel, the extrusion force of the wheel hub rotation will cause the gravel to hit the parts inside the hub through the hollows between the support columns, causing damage to the brake disc or other components installed inside the hub phenomenon, and at the same time lead to the phenomenon that the wheel hub is prone to safety hazards when driving

Embodiment approach
[0026] As an embodiment of the present invention, a winding disk 5 is fixed on the top of the winding rod 42, and a steel wire string 43 is coiled in the winding disk 5; 5, and then when the steel wire string 43 drives a plurality of elastic metal sheets 41 to flatten, the wound steel wire string 43 will synchronously drive the winding rod 42 to rotate in the winding cavity 31, so that the winding rod 42 can generate a rotational force to The coiled elastic metal sheet 41 is released, and at the same time, the pulling force of the steel wire rope can make the elastic metal sheet 41 can be stably unfolded, effectively preventing the elastic metal sheet 41 from only acting on the upper end of the elastic metal sheet 41 due to the pulling force of the steel wire string 43, causing the elastic metal The phenomenon that the bottom of the thin plate 41 cannot be stably unfolded will further affect the stable unfolding effect of the elastic metal thin plate 41; The reverse rotation o...

The invention belongs to the technical field of automobile hubs, and particularly relates to a lightweight aluminum alloy hub. The lightweight aluminum alloy hub comprises a wheel disc body. Multiplesupporting plates are arranged between the wheel disc body and a wheel core in the circumferential direction. Annular sliding grooves are formed in the cavity wall of the inner ring of the wheel discbody. A winding cavity is formed on one side wall of each of the multiple supporting plates, and elastic metal thin plates are rotationally wound in the multiple winding cavities through winding rods.The upper portions of one ends of the elastic metal thin plate are connected to a steel wire thin rope, and each elastic metal thin plate slides in the corresponding annular sliding groove between the two corresponding adjacent supporting plates through the steel wire thin rope. The steel wire thin rope is annularly coiled in the annular sliding grooves, the two ends of the steel wire thin rope are wound on two wire winding barrels correspondingly, and one wire winding barrel is connected to the output end of a drive motor through a rotating column. A driving gear is fixed to the output end of the drive motor, and a driven gear is arranged on the side face of the driving gear in an engaged manner. The driven gear is rotationally connected to the side walls of the supporting plates throughthe rotating column. The service life of the hub in long-time running is prolonged.
Description
technical field [0001] The invention belongs to the technical field of automobile wheel hubs, in particular to a lightweight aluminum alloy wheel hub. Background technique [0002] The hub is a barrel-shaped, center-mounted metal part on the axle that supports the tire inside the tire. Also known as rims, steel rims, wheels, and tire bells. There are many types of wheels according to diameter, width, molding method, and material. Aluminum alloy wheels have various structural designs such as integral type and multi-piece combination; in terms of appearance, there are wide spokes, narrow spokes, multiple spokes, and few spokes And many other shapes and designs. [0003] The Chinese patent discloses a lightweight aluminum alloy wheel hub with a hollow structure. The lightweight aluminum alloy wheel hub with a hollow structure includes an outer hub, an inner hub and a support column. The outer wall of the outer hub is fixedly connected to the hub through the support column. T...
