Description

Technical field:

[0001] The utility model relates to the technical field of automobile parts, and more specifically to a wheel hub with an insert. Background technology:

[0002] The wheel hub is a cylindrical metal part with the inner profile of the tire supporting the tire, and the center is mounted on the shaft. There are many types of wheel hubs according to diameter, width, molding method, and material. The wheel hub generally includes the rim, spokes, flange, bead seat, etc.

[0003] Conventional aluminum alloy wheels have spokes connected to the rim, that is, the outer ends of the spokes are formed on the rim at the front side of the rim. This structure has several disadvantages:

[0004] 1. The wall thickness of the connection between the spokes and the rim is very thick, which is prone to shrinkage during casting, easy to break and increase the failure rate, and the weight of the wheel is also heavy;

[0005] 2. Because the outer end of the spoke is formed onto the rim, the wheel with this structure cannot achieve the effect of full rim polishing, and the rim cannot be lathe-machined and cut as a whole.

[0006] At the same time, existing wheel products often have a variety of center hole diameters and mounting plate offsets for the same wheel shape to meet different loading requirements, which will increase production costs for wheel manufacturers. At the same time, because wheels of the same shape only differ in local size, they are difficult to distinguish from the appearance, which also brings difficulties to production management. Utility model content:

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a wheel hub with an insert, which disconnects the connection between the spokes and the rim and connects to the rim by installing the insert. This structure allows the entire circle of the rim at the front to be cut by a lathe, thereby improving the surface finish; and the insert can visually realize the connection between the rim and the spokes, thereby enhancing the high-end feel of the hub's appearance; and the connection between the spokes and the rim is disconnected, so that this part does not need to be too thick, thereby reducing the weight of the hub, achieving lightweight, reducing shrinkage problems, and improving the pass rate.

[0008] The solution of the utility model to solve the technical problem is:

[0009] A wheel hub with inserts comprises a wheel hub body, wherein the wheel hub body comprises a hub portion, spokes and a rim. The spokes comprise a plurality of spokes, wherein the inner end of each spoke is formed on the hub portion and the outer end is formed on the rim below the wheel flange at the front portion.

[0010] An insert is fixed on the front wall surface at the outer end of the spoke, and the outer end of the rear part of the insert is close to or closely attached to the rim at the front end.

[0011] An extension portion extending rearward is formed on the rear wall surface at the outer end of the spoke, and the rear end of the extension portion is formed on the front side wall of the rim below the wheel flange at the front portion.

[0012] The wheel spokes are composed of five spokes, and all the spokes are evenly distributed on the outer side wall of the hub with the central axis of the central through hole of the hub as the center.

[0013] A long through slot extending outward is formed in the middle of each spoke, a mounting groove extending backward is formed in the middle of the front wall surface of the outer end of the spoke, the outer end of the mounting groove extends out of the outer end surface of the spoke, and the inner end of the mounting groove extends out of the outer end surface of the long through slot of the spoke.

[0014] The locking cam of the bolt is inserted into the annular groove formed on the inner wall of the locking cam, and the locking cam is pressed against the locking cam of the locking cam, and the locking cam is pressed against the locking cam of the locking cam.

[0015] The upper raised strip and the lower raised strip ensure that when the insert is installed, the bottom surface of the upper raised strip is in close contact with the outer end surface of the corresponding spoke, and the top surface of the lower raised strip is in close contact with the outer end surface of the elongated through groove of the corresponding spoke. When the lower vertical embedding part of the insert is stuck in the left and right inner walls of the corresponding installation groove, it is not easy to rotate, thereby ensuring firm positioning.

[0016] An aperture offset replacement annular sheet is pressed against the rear wall surface of the hub, a main center through hole is formed in the middle of the aperture offset replacement annular sheet, a sleeve portion extending forward is formed at the inner wall of the main center through hole, the sleeve portion is inserted into the center through hole of the hub, the outer wall of the sleeve portion is tightly against the inner wall of the center through hole of the hub, a plurality of connecting through holes are formed on the edge of the aperture offset replacement annular sheet, and the connecting through holes are connected and correspond to the corresponding PCD holes formed on the edge of the hub.

[0017] The outstanding effects of the utility model are:

[0018] Compared with the existing technology, it disconnects the connection between the spokes and the rim and connects them to the rim by installing inserts. This structure allows the entire front rim to be cut by a lathe to improve the surface finish. The inserts can visually connect the rim and the spokes, enhancing the high-end look of the wheel hub. Moreover, the connection between the spokes and the rim is disconnected, so that this part does not need to be too thick, which reduces the weight of the wheel hub, achieves lightweight, reduces shrinkage problems, and improves the pass rate.

[0019] It can install a hole offset replacement annular piece with different center hole diameters and offsets in the wheel hub body, thereby changing the center hole diameter and offset for the installation of the wheel hub, so that it meets the center hole diameter and offset dimensions of the wheel hub required by the corresponding vehicle model, so that it can be installed on the installation position of the corresponding vehicle model, so that the same wheel hub can meet the vehicle models with various center hole diameters and offset requirements, and the scope of application is greatly improved.

[0023] Figure 4 It is a schematic diagram of the structure of the insert;

[0024] Figure 5 It is a schematic diagram of the partial structure of the hub body without the insert. Specific implementation method:

[0025] For example, see Figures 1 to 5 As shown, a wheel hub with inserts includes a hub body 10, the hub body 10 includes a hub portion 11, spokes 12 and a rim 13, the spokes 12 include five spokes 121, the inner end of each spoke 121 is formed on the hub portion 11, and the outer end is formed on the rim 13 below the rim 14 at the front, all the spokes 121 are evenly distributed on the outer side wall of the hub portion 11 with the central axis of the central through hole of the hub portion 11 as the center.

[0026] An insert 20 is fixed on the front wall surface at the outer end of the spoke 121, and the outer end of the rear portion of the insert 20 is close to or in close contact with the front wall surface at the corresponding position of the rim 14 at the front end.

[0027] The spokes 121 are disconnected from the front wheel rim 14. This structure allows the front wheel rim 14 to be turned in a full circle by a lathe tool in subsequent processing to improve the surface finish. Subsequently, only a transparent powder layer needs to be coated on this surface to form a bright surface for the entire front wheel rim 14.

[0028] Moreover, the spokes 121 are disconnected from the front rim 14, so that the thickness of the formed part here is greatly reduced, reducing the weight of the entire wheel hub, achieving lightweight. The reduced thickness also reduces shrinkage problems and improves the pass rate.

[0029] Furthermore, an extension portion 122 extending backward is formed on the rear wall surface at the outer end of the spoke 121, and the rear end of the extension portion 122 is formed on the front side wall of the rim 13 below the rim 14 at the front.

[0030] Each of the spokes 121 is formed with an outwardly extending elongated through slot 123 in the middle, and a rearwardly extending mounting groove 124 is formed in the middle of the front wall surface of the outer end of the spoke 121. The outer end of the mounting groove 124 extends out of the outer end surface of the spoke 121, and the inner end of the mounting groove 124 extends out of the outer end surface of the elongated through slot 123 of the spoke 121.

The bolt 2 in the figure is a simple schematic diagram, and it can adopt various conventional bolts such as conventional hexagon socket bolts, cross bolts or flat bolts.

[0032] Among them, it is also possible to change the screw hole 1 into a connecting hole, and change the bolt 2 into a pin, and the pin shaft of the pin can be inserted into the corresponding front middle through hole 211, and the rear end of the pin shaft is clamped into the corresponding connecting hole, and the head of the pin is inserted into the annular groove formed on the inner wall of the front end of the front middle through hole 211, and the rear end face of the head of the pin is pressed against the rear end face of the annular groove formed on the inner wall of the front end of the corresponding front middle through hole 211, so as to fix the insert 20.

[0033] The insert 20 of this embodiment can be made of PC+ABS material.

[0034] Furthermore, a middle protrusion 24 extending outward is formed in the middle of the top surface of the lower vertical inlaying portion 21 of the inlay 20, and side protrusions 25 extending outward are formed on the left and right parts of the top surface of the lower vertical inlaying portion 21, and the bottom surface of the side protrusion 25 is closely attached to or close to the outer end surface of the corresponding spoke 121;

[0035] The rear wall surfaces of the middle protrusion 24 and the edge protrusion 25 are close to or in close contact with the front wall surface of the rim 14 at the front end.

[0036] The front wall surfaces of the spokes 121 at the left and right sides of the elongated through slot 123 are formed with protruding reinforcement portions 3 extending forward.

[0037] Furthermore, an aperture offset replacement annular plate 30 is pressed against the rear wall surface of the hub 11, a main center through hole is formed in the middle of the aperture offset replacement annular plate 30, a sleeve portion 31 extending forward is formed at the inner wall of the main center through hole, the sleeve portion 31 is inserted into the center through hole of the hub 11, the outer wall of the sleeve portion 31 is tightly attached to the inner wall of the center through hole of the hub 11, and a plurality of connecting through holes 32 are formed on the edge of the aperture offset replacement annular plate 30, and the connecting through holes 32 are connected and correspond to the corresponding PCD holes 111 formed on the edge of the hub 11.

[0038] It can install an aperture offset replacement annular plate 30 with different center hole diameters and offsets in the wheel hub body 10, and the outer wall of its sleeve body 31 is close to the inner wall of the center through hole of the hub 11, thereby changing the center through hole diameter for installation of the hub 11 of the wheel hub body 10 (at this time, the diameter of the inner wall of the sleeve body 31 is the center through hole diameter φA for installation, and the original center through hole diameter of the hub 11 is φB), and the front wall surface of the aperture offset replacement annular plate 30 is pressed against the rear end surface of the hub 11, so that the distance between the rear end surface of the aperture offset replacement annular plate 30 and the vertical line of the middle of the rim 13 is the installation disk offset ET2 (the original distance between the rear wall surface of the hub 11 and the vertical line of the middle of the rim 13 is the installation disk offset ET1), which is different from the original one, so that it meets the dimensions of the center hole diameter and the installation disk offset of the wheel hub required by the corresponding vehicle model, so that it can be installed on the installation position of the corresponding vehicle model.

[0039] That is, the wheel hub body 10 of some vehicle models requires a 17-inch wheel hub, but the inner diameter of the central through hole of the hub portion 11 required is different. At the same time, the distance between the vertical line from the rear wall surface of the hub portion 11 to the middle of the rim 13 is also different. At this time, it is necessary to install an aperture offset replacement annular plate 30 of corresponding size, so as to change the inner diameter of the central through hole for installing the hub portion 11 of the wheel hub body 10 (the inner diameter at this time is the inner diameter φA of the sleeve portion 31), and the installation plate offset at this time is the distance between the rear end face of the aperture offset replacement annular plate 30 to the vertical line in the middle of the rim 13, and the offset is also changed to meet the installation needs of the corresponding vehicle model.

[0040] With this structure, the same wheel hub only needs to be installed with different sizes of aperture offset replacement annular pieces 30 to meet the requirements of installation in vehicles with different center hole diameters and offsets, thereby greatly improving the scope of application.
