Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to a wheel hub with a compression-resistant structure. Background Art

[0002] The wheel hub is also called the wheel rim, steel rim, wheel, or tire bell. It is a cylindrical metal part that supports the tire with its inner profile and is mounted on the shaft. There are many types of wheel hubs, depending on the diameter, width, molding method, and material. Depending on the characteristics and requirements of different models, the wheel hub surface treatment process will also take different methods, which can be roughly divided into two types: baking varnish and electroplating.

[0003] The existing wheel hub is fixed to the drive shaft of the car by bolts, but most of the bolts are exposed to the outside. The driving environment of the car is changeable. In some muddy and dusty areas, dust and gravel will enter the surface of the bolts, making it inconvenient for personnel to remove them when maintenance is required. Utility Model Content

[0004] The purpose of the utility model is to provide a wheel hub with a compression-resistant structure to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a wheel hub with a compression-resistant structure, comprising a wheel hub body, a surface of the wheel hub body is provided with a protective component, and the protective component comprises:

[0006] The groove is formed on the surface of the wheel hub body, and a cavity is formed inside the wheel hub body. A ring is rotatably connected to the inner wall of the cavity. A limit rod is fixed on the surface of the ring. A through hole is formed on the surface of the groove. One end of the limit rod away from the ring passes through the through hole. A volute spring is fixed on the surface of the ring. One end of the volute spring away from the ring is fixed on the inner wall of the cavity. A protective cover is provided on the right side of the wheel hub body. A limit column is fixed on the side of the protective cover close to the wheel hub body. A linkage groove is formed on the surface of the limit column. A limit groove is formed on the surface of the limit column. The limit column is pressed into the groove so that the limit rod enters the limit groove to stabilize the protective cover. This can prevent debris from entering the bolt surface when driving in some dusty and muddy areas, which affects the disassembly for maintenance by personnel. At the same time, the wheel hub body is made of aluminum alloy with good pressure resistance. Compared with steel, aluminum is light, which is beneficial to control, stability and performance.

[0007] Preferably, the linkage groove is arranged in an arc shape, so that the limiting rod drives the ring to rotate.

[0008] Preferably, the limiting groove is arranged in a ring shape, and the limiting rod enters the limiting groove to perform interference limiting.

[0009] Preferably, the limiting rods, linkage grooves and limiting grooves are each provided in four groups, and the four groups of limiting rods, linkage grooves and limiting grooves are all arranged in a circular array with the center of the groove and the limiting column as the axis, thereby increasing the stability of the protective cover and the hub body.

[0010] Preferably, the groove is consistent with the shape of the limiting column, which is convenient for installation.

[0011] Preferably, the limiting groove and the linkage groove are interconnected, which can prevent the limiting rod from failing to move normally.

[0012] Compared with the prior art, the utility model provides a wheel hub with a compression-resistant structure, which has the following beneficial effects:

[0013] The wheel hub with a compression-resistant structure presses the limit column into the groove through the provided protection component, presses the protection cover, the limit rod moves on the inner wall of the linkage groove, and the ring rotates. When the protection cover is fitted with the surface of the wheel hub body, the position of the limit rod and the limit groove are parallel, the volute spring is released, the ring drives the limit rod to reverse, and the limit rod then enters the limit groove to stabilize the protection cover. This can prevent debris from entering the bolt surface when driving in some dusty and muddy areas, thereby affecting the disassembly for maintenance by personnel. During disassembly, the protection cover is rotated and pulled outward to separate the protection cover from the wheel hub body. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a wheel hub with a pressure-resistant structure, comprising a wheel hub body 1, a protective component 2 is arranged on the surface of the wheel hub body 1, and the protective component 2 includes: a groove 20, a cavity 21, a ring 22, a limiting rod 23, a through hole 24, a volute spring 25, a protective cover 26, a limiting column 27, a linkage groove 28, and a limiting groove 29.

[0020] The groove 20 is provided on the surface of the hub body 1, a cavity 21 is provided inside the hub body 1, a circular ring 22 is rotatably connected to the inner wall of the cavity 21, a limiting rod 23 is fixed on the surface of the circular ring 22, a through hole 24 is provided on the surface of the groove 20, an end of the limiting rod 23 away from the circular ring 22 passes through the through hole 24, a volute spring 25 is fixed on the surface of the circular ring 22, an end of the volute spring 25 away from the circular ring 22 is fixed on the inner wall of the cavity 21, a protective cover 26 is provided on the right side of the hub body 1, a limiting column 27 is fixed on the side of the protective cover 26 close to the hub body 1, a linkage groove 28 is provided on the surface of the limiting column 27, and a limiting A limiting groove 29 is provided on the surface of the positioning column 27, and the limiting column 27 is pressed into the groove 20. When the limiting rod 23 enters the linkage groove 28, the protective cover 26 is pressed, and the limiting rod 23 moves on the inner wall of the linkage groove 28, driving the ring 22 to rotate. When the protective cover 26 is made to fit the surface of the hub body 1, the limiting rod 23 is parallel to the position of the limiting groove 29, the volute spring 25 is released, and the ring 22 drives the limiting rod 23 to reverse, and the limiting rod 23 then enters the limiting groove 29 to stabilize the protective cover 26. This can prevent debris from entering the bolt surface when driving in some dusty and muddy areas, thereby affecting the disassembly of personnel for maintenance.

[0021] The linkage groove 28 is set to an arc shape. When it continuously conflicts with the limit rod 23, the limit rod 23 can drive the ring 22 to rotate. The limit groove 29 is set to a ring shape. The spiral spring 25 is released to drive the ring 22 to reverse, so that the limit rod 23 can enter the limit groove 29 and perform conflict and limit. The limit rod 23, the linkage groove 28, and the limit groove 29 are all set in four groups, and the four groups of limit rods 23, the linkage groove 28, and the limit groove 29 are all arranged in a circular array with the center of the groove 20 and the limit column 27 as the axis, thereby increasing the stability of the protective cover 26 and the hub body 1. The shape of the groove 20 is consistent with that of the limit column 27, which facilitates the entry of the limit column 27. The limit groove 29 and the linkage groove 28 are interconnected, and will not affect the normal movement of the limit rod 23.

[0022] When the personnel completes the fixing of the hub body 1 and the drive shaft by bolts, the personnel presses the limit column 27 into the groove 20, so that the limit rod 23 enters the linkage groove 28. The personnel can adjust it by rotating the protective cover 26. When the limit rod 23 enters the linkage groove 28, the protective cover 26 is pressed, and the limit rod 23 moves on the inner wall of the linkage groove 28, thereby driving the ring 22 to rotate, so that the spiral spring 25 is rolled up. When the protective cover 26 is fitted with the surface of the hub body 1 and completely covers the mounting hole of the bolt, the limit rod 23 is parallel to the position of the limit groove 29. At this time, the spiral spring 25 is released, so that the ring 22 drives the limit rod 23 to reverse, and the limit rod 23 then enters the limit groove 29, and the inner wall of the limit groove 29 is The surface of the limit rod 23 is in contact, thereby stabilizing the protective cover 26, and can prevent debris from entering the bolt surface when driving in some dusty and muddy areas, which affects the disassembly for maintenance by personnel. When the hub body 1 needs to be replaced, the personnel rotates the protective cover 26 counterclockwise to move the limit rod 23 into the limit groove 29. When the protective cover 26 can no longer continue to rotate counterclockwise, the limit rod 23 is located at the junction of the limit groove 29 and the linkage groove 28. At this time, the personnel pulls the protective cover 26 away from the side of the hub body 1, and the limit rod 23 again contacts the inner wall of the linkage groove 28, so that the limit rod 23 drives the ring 22 to reverse until the protective cover 26 is separated from the hub body 1. At this time, the personnel can remove the bolts normally and replace or maintain the hub body 1.
