Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to a wheel hub with a protective function. Background Art

[0002] The wheel hub is a cylindrical metal part that supports the tire with its inner profile and is mounted on an axle. It is also called a wheel rim, steel rim, wheel, or tire bell. There are many types of wheel hubs, depending on the diameter, width, molding method, and material. The wheel hub is also the part where the axle is mounted in the center of the wheel, and is also called a wheel rim or steel rim.

[0003] However, the existing wheel hub does not have a protective effect when in use, which results in the inability to effectively prevent impurities such as sand, mud, etc. from entering the wheel hub when the vehicle is traveling on a bad road, thereby reducing the wear on the internal parts of the wheel hub, thereby reducing the service life of the wheel hub and increasing maintenance costs.

[0026] The fixing assembly 2 includes: a movable rod 21, the movable rod 21 is hinged at the bottom of the connecting plate 38, a fixed rod 22 is fixedly installed on the right side of the movable rod 21, a limiting rod 23 is hinged on the surface of the fixed rod 22, one end of a torsion spring 24 is fixedly installed on the inner side of the limiting rod 23, and the other end of the torsion spring 24 is fixedly installed on the surface of the fixed rod 22, and a limiting plate 25 is fixedly installed inside the fixing ring 31.

When the limiting rod 23 is active, it will be fixed by the fixing ring The circular groove 310 provided on the fixing ring 31 interferes with the inner part of the circular groove 310, thereby fixing the limiting rod 23, improving the stability and fixing effect of the protection block 35 when in use, and improving the safety of the wheel hub 1 when in use; a circular groove 310 is provided on the surface of the fixing ring 31, which can drive the fixing shaft 37 to slide inside the fixing ring 31; a sliding groove 320 is provided on the surface of the turntable 32, which can drive the sliding rod 34 to slide on the surface of the turntable 32; a square groove 330 is provided on the surface of the connecting plate 33, which can drive the sliding shaft 36 to slide on the surface of the connecting plate 33; a hole 250 is provided on the surface of the limiting plate 25, and the fixing rod 22 can be used to penetrate the limiting plate 25 for limiting.

[0027] When the wheel hub 1 is driving in a harsh area, the wheel hub 1 needs to be protected. The fixed shaft 37 can be manually slid to the right on the surface of the fixed ring 31.
