High-strength hub center shaft protector

Abstract

The invention relates to a high-strength hub center shaft protector. The high-strength hub center shaft protector comprises a first hub. A second hub is arranged on one side of the first hub, center holes are formed in the first hub and the second hub, the two center holes are located in the same horizontal line, a first center shaft is arranged between the center holes, the two ends of the firstcenter shaft are connected with second center shafts through locking devices, and one ends of the second center shafts stretch out of the center holes of the first hub and the second hub. Fixing blocks are arranged in inner cavities of the second center shafts, the tops and the bottoms of the fixing blocks are connected with pin shafts through springs, and one ends of the pins penetrate out of thesecond center shafts. The first hub and the second hub are connected through the three sections of center shafts, dustproof covers can be mounted on the inner sides and the outer sides of the centerholes of the first hub and the second hub, the center shafts and the hubs are protected, it is avoided that dust falls into the center holes of the hubs, so that the center shafts and the hole walls of the center holes of the hubs are abraded, the service life is prolonged, and therefore the driving safety is guaranteed.

Description

technical field [0001] The invention relates to a high-strength hub central shaft protector, which belongs to the field of auto parts. Background technique [0002] The wheel hub is also called the rim, the steel ring, the wheel, and the tire bell. It is a barrel-shaped metal part that is supported by the inner profile of the tire and the center is mounted on the shaft. There are many types of hubs according to the diameter, width, molding method, and material. Alloy wheels are mostly made of aluminum as the basic material, and metal elements such as manganese, magnesium, chromium, and titanium are appropriately added. Compared with steel wheels, alloy wheels have the characteristics of energy saving, safety, and comfort. Therefore, more and more cars have put The alloy hub is listed as standard configuration. After the hub is connected with the central shaft, the two ends of the central shaft protrude from the central hole of the hub respectively. During use, because there ...

[0002] The wheel hub is also called the rim, the steel ring, the wheel, and the tire bell. It is a barrel-shaped metal part that is supported by the inner profile of the tire and the center is mounted on the shaft. There are many types of hubs according to the diameter, width, molding method, and material. Alloy wheels are mostly made of aluminum as the basic material, and metal elements such as manganese, magnesium, chromium, and titanium are appropriately added. Compared with steel wheels, alloy wheels have the characteristics of energy saving, safety, and comfort. Therefore, more and more cars have put The alloy hub is listed as standard configuration. After the hub is connected with the central shaft, the two ends of the central shaft protrude from the central hole of the hub respectively. During use, because there is no protective gear, the dust will fall into the central hole of the hub. Time will block the gap, wear the center shaft and the hole wall of the center hole of the hub, there is a safety hazard, and it is not very convenient to clean the sundries on the surface of the center hole daily, so further improvement is needed
