Description

Technical Field

[0001] This utility model relates to the field of wheel hubs, and in particular to a wheel hub structure for commercial vehicles. Background Technology

[0002] Commercial vehicle aluminum alloy wheels are forged into a single piece, and then processed through drilling, heat treatment, and polishing to achieve lightweight, heat dissipation, and durability, making them more durable than ordinary steel wheels.

[0003] Commercial vehicle wheel hub structure and installation effect, as shown Figure 1 As shown, it includes an integrally formed hub body 11 and a connecting plate 12 located on one side of the hub body 11. A through hole 121 is coaxially opened on the connecting plate 12. The middle part of the connecting plate 12 protrudes outward and forms a mounting surface 13. Multiple mounting holes 14 are evenly opened on the mounting surface 13 around the axis of the connecting plate 12.

[0004] The wheel hub body 11 needs to be connected to the vehicle body. The mounting hole 14 is for the connecting bolt 16 to pass through. After the bolt 16 passes through, the nut 17 is tightened. The nut 17 is pressed against the mounting surface 13 to complete the installation.

[0005] After installation, the ends of the bolts, nuts, and the shafts connected at the through holes are all exposed on the outside of the wheel hub, making the overall appearance very unsightly. While some users prioritize practicality over aesthetics, others, especially in the US market, prioritize appearance. Figure 1 Commercial vehicle wheel hubs with this shape have no market in the local area. Utility Model Content

[0006] In order to improve the aesthetic appearance of commercial vehicle wheel hubs, this application provides a commercial vehicle wheel hub structure.

[0007] The commercial vehicle wheel hub structure provided in this application adopts the following technical solution:

[0008] A commercial vehicle wheel hub structure includes an integrally formed wheel hub body and a connecting plate located on one side of the wheel hub body. The connecting plate has a through hole coaxially formed, and the middle part of the connecting plate protrudes outward to form a mounting surface. Multiple mounting holes are evenly formed on the mounting surface around the axis of the connecting plate.

[0009] It also includes a hub disc and a clamping member. The hub disc is truncated cone-shaped. Multiple first holes are evenly opened on the conical surface of the hub disc around the axis of the hub disc. The multiple first holes correspond one-to-one with multiple mounting holes. The diameter of the first hole is larger than the diameter of the corresponding nut. The clamping member is connected to the shank of the bolt and is used to drive the hub disc to abut against the mounting surface.

[0010] By adopting the above technical solution, the frustum-shaped wheel hub disc can cover the axle, and the clamping part and bolt connection can cover the exposed bolts and nuts. Its conical shape can optimize the appearance of the wheel hub and meet the requirements of the shape. The first hole corresponds to the mounting hole and its diameter is larger than that of the nut. The entire wheel hub disc can be added to the installed wheel hub body without removing the nut and then adding it, which improves the convenience of installation.

[0011] Preferably, the clamping member includes multiple mounting blocks. The first hole is tapered towards the hub body. Each mounting block includes a hollow outer shell and a connecting post fixed to the inner end wall of the outer shell. The connecting post has a threaded groove. The mounting block is threaded to the shank of the bolt through the connecting post. The mounting block is coaxial with the first hole. The end of the mounting block near the hub body abuts against the inclined inner wall of the first hole. The connecting post is located on the side of the nut away from the hub body.

[0012] By adopting the above technical solution, the mounting block applies force to the wheel hub disc and presses against the mounting surface by pressing against the inclined inner wall of the first hole. The mounting block perfectly covers the bolts, nuts and the first hole. The hollow outer shell can reduce weight and meet the requirements of lightweighting.

[0013] Preferably, the mounting block further includes several reinforcing ribs located inside the outer shell and evenly distributed around the connecting column. The reinforcing ribs are fixed to the outer shell and the connecting column.

[0014] By adopting the above technical solution, the reinforcing ribs connect the outer shell and the connecting column. The circumferentially distributed reinforcing ribs can balance the force, enhance the structural strength of the mounting block, and improve the durability of the clamping parts.

[0015] Preferably, an elastic element is provided between several reinforcing ribs and the nut.

[0016] By adopting the above technical solution, the elastic force of the elastic element can act on both the nut and the mounting block simultaneously, which can reduce the risk of loosening of the connection between the nut and the mounting block.

[0017] Preferably, the elastic element includes a ring and a spring. The ring is sleeved on the connecting post and is interference-fitted with the connecting post. The ring abuts against a plurality of reinforcing ribs. One end of the spring is fixedly disposed inside the ring, and the other end of the spring abuts against a nut.

[0018] By adopting the above technical solution, when the connecting block is disassembled, the spring will not detach from the connecting block and pop out independently, thus avoiding the loss of the spring.

[0019] Preferably, the inner wall of the outer casing is located on the side of the nut away from the hub body, and is in the shape of a regular polygonal groove.

[0020] By adopting the above technical solution, since the ring is located inside the outer shell, regardless of the diameter of the ring, there is always a gap between the ring and the corner of the regular polygonal groove. The operator can insert tools such as barbs into the gap and then abut against the back of the ring to remove it.

[0021] Preferably, a plurality of force-applying grooves are uniformly formed on the outer surface of the outer shell along the circumferential direction. The force-applying grooves are formed along the axial direction of the mounting block. The plurality of force-applying grooves correspond one-to-one with the plurality of surfaces of the regular polygonal groove. The center of the force-applying groove is concave into an arc shape.

[0022] By adopting the above technical solution, the force groove is mainly to facilitate the operator to manually rotate the installation block, so that the force can be applied and slippage can be prevented.

[0023] Preferably, the first hole is a countersunk hole, and the clamping member includes multiple mounting blocks. Each mounting block includes an inner hollow outer shell and a connecting post fixed to the inner end wall of the outer shell. The connecting post has a threaded groove. The mounting block is threaded to the shank of the bolt through the connecting post. The mounting block is coaxially arranged with the countersunk hole. The diameter of the countersunk hole is larger than the diameter of the nut. The end of the mounting block near the hub body abuts against the stepped surface of the countersunk hole. The connecting post is located on the side of the nut away from the hub body.

[0024] By adopting the above technical solution, after the mounting block is installed on the bolt, the mounting block is pressed against the countersunk hole step surface, thereby applying force to the wheel hub disc to press against the mounting surface.

[0025] The main technical effects of this utility model are reflected in the following aspects:

[0026] 1. The truncated cone-shaped wheel hub disc of this utility model can cover the axle, and the clamping part and bolt connection can cover the exposed bolts and nuts. Its conical shape can optimize the appearance of the wheel hub and meet the requirements of the shape. The first hole corresponds to the mounting hole and its diameter is larger than that of the nut. The entire wheel hub disc can be added to the installed wheel hub body without removing the nut and then adding it, which improves the convenience of installation.

[0027] 2. The mounting block of this utility model applies force to the wheel hub disc by pressing against the inclined inner wall of the first hole, and the mounting block perfectly covers the bolts, nuts and the first hole. The hollow outer shell can reduce weight and meet the requirements of lightweighting. Attached Figure Description

[0036] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0037] This application discloses a commercial vehicle wheel hub structure. Example

[0038] Reference Figures 1-3 This embodiment of a commercial vehicle wheel hub structure includes an integrally formed hub body 11 and a connecting plate 12 located on one side of the hub body 11. A through hole 121 is coaxially formed on the connecting plate 12. A mounting surface 13 is formed by an outwardly protruding center of the connecting plate 12. Multiple mounting holes 14 are evenly formed on the mounting surface 13 around the axis of the connecting plate 12. Multiple heat dissipation holes 15 are also formed circumferentially on the connecting plate 12. These heat dissipation holes 15 are located on the outer side of the mounting block 31. Besides their heat dissipation function, the heat dissipation holes 15 also serve a decorative purpose.

[0039] Reference Figures 1-3 It also includes a hub disc 2 and a clamping member. The hub disc 2 is truncated cone-shaped. Multiple first holes 21 are evenly opened on the conical surface of the hub disc 2 around the axis of the hub disc 2. The multiple first holes 21 correspond one-to-one with multiple mounting holes 14. The diameter of the first hole 21 is larger than the diameter of the relevant nut 17. The clamping member is connected to the shank of the bolt 16 and is used to drive the hub disc 2 to abut against the mounting surface 13.

[0040] Reference Figures 1-3 The frustum-shaped wheel disc 2 can cover the through hole 121, and the fastening part connected to the bolt 16 can cover the exposed bolt 16 and nut 17. Its conical shape can optimize the appearance of the wheel and meet the requirements of the shape. The first hole 21 corresponds to the mounting hole 14 and its diameter is larger than that of the nut 17. The entire wheel disc 2 can be installed on the installed wheel body 11 without removing the nut 17, which improves the convenience of installation.

[0041] Reference Figures 4-6 The clamping component includes multiple mounting blocks 31. The first hole 21 is tapered towards the hub body 11. The mounting block 31 includes a hollow outer shell 32 and a connecting post 33 fixed to the inner end wall of the outer shell 32. The connecting post 33 has a threaded groove. The mounting block 31 is threaded to the shank of the bolt 16 through the connecting post 33. The mounting block 31 is coaxial with the first hole 21. The end of the mounting block 31 near the hub body 11 abuts against the inclined inner wall of the first hole 21. The connecting post 33 is located on the side of the nut 17 away from the hub body 11.

[0042] Reference Figures 4-6 The mounting block 31 applies force to the hub disc 2 and presses against the mounting surface 13 by abutting against the inclined inner wall of the first hole 21. The mounting block 31 perfectly covers the bolt 16, nut 17 and the first hole 21. The hollow outer shell 32 can reduce weight and meet the requirements of lightweighting.

[0043] Reference Figures 4-6 The mounting block 31 also includes several reinforcing ribs 34, which are located inside the outer shell 32 and are evenly distributed around the connecting post 33. The reinforcing ribs 34 are fixed to the outer shell 32 and the connecting post 33. The reinforcing ribs 34 connect the outer shell 32 and the connecting post 33. The evenly distributed reinforcing ribs 34 can balance the force, enhance the structural strength of the mounting block 31, and improve the durability of the clamping component.

[0044] Reference Figures 4-6 An elastic element 4 is provided between several reinforcing ribs 34 and the nut 17. The elastic force of the elastic element 4 can act on both the nut 17 and the mounting block 31 simultaneously, which can reduce the risk of loosening of the connection between the nut 17 and the mounting block 31.

[0045] Reference Figures 4-6The elastic element 4 includes a ring 41 and a spring 42. The ring 41 is fitted onto the connecting post 33 with an interference fit and abuts against several reinforcing ribs 34. One end of the spring 42 is fixed inside the ring 41, and the other end abuts against the nut 17. When the connecting block is disassembled, the spring 42 will not detach from the connecting block and pop out independently, thus preventing the loss of the spring 42. The end of the spring 42 that is fixed to the ring 41 is integrally injection molded with the ring 41. A stiffer metal spring 42 is selected. During the installation of the connecting block, the spring 42 will not initially abut against the nut 17, but will abut against the nut 17 in the last few turns, which can reduce the torque on the spring 42. Even if the spring 42 is subjected to torque, it can return to its original position, which basically does not affect the elastic force.

[0046] Reference Figures 4-6 The inner wall of the outer casing 32 is located on the side of the nut 17 away from the hub body 11, and is in the shape of a regular polygonal groove 322. Since the ring sleeve 41 is located inside the outer casing 32, regardless of the diameter of the ring sleeve 41, there is always a gap between the ring sleeve 41 and the corner of the regular polygonal groove 322. The operator can insert tools such as barbs into the gap space and then abut against the back of the ring sleeve 41 to remove the ring sleeve 41.

[0047] Reference Figures 4-6 Multiple force-applying grooves 321 are evenly distributed circumferentially on the outer surface of the outer casing 32. The force-applying grooves 321 are opened along the axial direction of the mounting block 31, and each of the multiple force-applying grooves 321 corresponds to a different surface of the regular polygonal groove 322. The center of the force-applying groove 321 is concave into an arc shape. The force-applying grooves 321 are mainly for the convenience of the operator to manually rotate the mounting block 31, so that force can be applied and slippage can be prevented. Example

[0048] The difference between Example 2 and Example 1 is that: (Refer to...) Figure 7 The first hole 21 is a countersunk hole 211. After the mounting block 31 is installed on the bolt 16, the mounting block 31 abuts against the stepped surface 212 of the countersunk hole 211, thereby causing the wheel hub disc 2 to abut against the mounting surface 13.

[0049] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
