Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a fastening component, a wheel hub cover mounting structure, and a wheel hub assembly. Background Technology

[0002] The wheel hub is a component of a car. As part of the wheel, in the current technology, to prevent external objects from causing wear and scratches to the outer surface of the wheel hub, or for users with decorative needs, wheel hub covers are often installed on the outer surface of the wheel hub. Currently, there are clip-on installation methods and wheel hub covers are connected by threads through the center hole of the wheel hub. However, the above connection methods are relatively cumbersome to install and remove, and also have the problem of unstable connection. In order to solve at least one of the above technical problems, it is necessary to develop a fastening component, a wheel hub cover mounting structure, and a wheel hub assembly. Utility Model Content

[0003] The purpose of this utility model is to provide a fastening component, a hub cover mounting structure, and a hub assembly to solve the above-mentioned technical problems. The moving block is abutted by the axially moving movable part, thereby extending out of the first component. The moving block extends out of the first component to abut the inner surface of the hub center hole, thereby completing the connection between the fastening component and the hub, which facilitates the installation of the hub cover. This connection method is simple, convenient to operate, and occupies little space.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A fastening assembly includes a first component, a movable member connected to the first component and axially movable, and a movable block connected to the first component and axially movable, which abuts against the movable member to extend radially out of the first component.

[0006] The movable block can be a single unit or multiple units arranged circumferentially around the axis of the first component. The movable component is located inside the first component, and the movable block is partially or completely movable inside the first component. The movable block is abutted by the axially moving movable component, thereby extending outside the first component. The movable block extends outside the first component to abut the inner surface of the hub's central hole, thus completing the connection between the fastening component and the hub, facilitating the installation of the hub cover. This connection method is simple, convenient to operate, and occupies little space.

[0007] Preferably, the movable block is hinged to the first component;

[0008] The movable component includes a disc body that can abut against a movable block during axial movement, causing the movable block to rotate around a hinge end, and a transmission end that allows the disc body to move axially within the first component.

[0009] The radial end face of the disc is positioned opposite to the side of the moving block near the center of the first component.

[0010] The radial end face of the disc abuts against the movable block, thereby causing the movable block to rotate around the hinge end and extend beyond the first component. The hinge end is located between the side of the movable block closest to the disc and the outer side of the first component.

[0011] The first component is provided with a first through slot for accommodating the movable block, a hinge hole hinged to the movable block, and a first cavity providing space for the axial movement of the movable part. The first through slot provides the movable block with movement space; wherein the first through slot is connected to the first cavity. The hinge hole is provided on the side wall of the first through slot facing the movable block. When the transmission end rotates, the disc coaxially connected to the transmission end moves axially. During the movement of the disc, it abuts against the surface of the movable block near the center of the first component, thereby causing the movable block to rotate around the hinge end that is hinged to the first component. Thus, the movable block extends out of the first component and abuts against the inner surface of the center hole of the hub, thereby completing the connection between the fastening component and the hub, which is convenient for installing the hub cover. This connection method is simple and occupies little space.

[0012] Preferably, the transmission end includes a shaft movably connected to the first component and a guide portion for guiding the movement of the disc.

[0013] One end of the shaft is threadedly connected to the disc. The shaft, disc, and first assembly are coaxially arranged. Through the rotation of the shaft and the guiding action of the guide part on the disc, the disc can move axially along the first assembly due to the threaded connection between the disc and one end of the shaft. After the disc moves axially a certain distance via the shaft, the threaded connection provides a self-locking function, preventing the disc from moving spontaneously and improving the operational stability of the fastening assembly. The transmission block can be removed after the disc has moved axially a certain distance.

[0014] Preferably, the first component is configured as a first cavity that provides space during the axial movement of the disk.

[0015] The guide portion includes a slot and a locking block that engages with the slot;

[0016] The slot is disposed on the disc body and the block is disposed on the first cavity, or the slot is disposed on the first cavity and the block is disposed on the disc body. The shaft, the disc body, and the multiple moving blocks are coaxially arranged; wherein the extension direction of the slot and the block is parallel to the axial direction of the first component, and the slot and the block are arranged in groups of one or more; in this technical solution, the slot is disposed on the disc body and the block is disposed on the first cavity, so that the disc body moves axially under the transmission of the shaft. Under the guidance of the slot and the block, the disc body moves axially within the first cavity under the transmission of the shaft. This structure requires less space and has a simple transmission method;

[0017] Preferably, the disk body has a first end face that can abut against the movable block in a radial direction;

[0018] The movable block is provided with a contact surface that abuts against the first end face, thereby allowing the movable block to rotate around the hinge end. During the axial movement of the disc, the first end face abuts against the contact surface, thereby controlling the amount by which the movable block extends relative to the first component.

[0019] Preferably, the contact surface includes a second end face and a third end face disposed near the side of the disc body, and the second end face and the third end face are disposed sequentially along the axial direction of the first component;

[0020] The second end face gradually approaches the center of the first component from the third end face. When the first end face abuts against the second end face, the moving block corresponding to the position of the disc does not extend or only extends partially, but the extension is not enough to effectively abut against the inner surface of the hub center hole, thus facilitating the initial placement of the fastening component into the hub center hole and making it easy to adjust the installation position; when the disc moves to the point where the first end face abuts against the third end face, the moving block corresponding to the position of the disc extends and effectively abuts against the inner surface of the hub center hole. This fastening component has a simple structure, is easy to use, and occupies little space.

[0021] Preferably, the cross-sectional shape of the contact surface along the axial direction of the first component is one of the following: arc-shaped, straight-line, wavy, or polygonal. In this technical solution, the cross-sectional shape of the contact surface along the axial direction of the first component is arc-shaped.

[0022] Preferably, the movable member has an abutment block on the side away from the disc body. In the initial state, the height of the abutment block is less than the height of the movable block along the axial direction of the first component.

[0023] Preferably, the first component includes a first member and a second member arranged sequentially along the axial direction and connected to each other. The separate configuration facilitates assembly.

[0024] Preferably, the fastening assembly further includes a second assembly connected to the first assembly. The first and second assemblies are coaxially connected and arranged sequentially from the outside to the inside. Specifically, the first and second assemblies are threaded together. The second assembly allows the transmission end to rotate, thereby causing the disc to move axially. The rotation of the second assembly allows the moving block to extend, facilitating the installation of the fastening assembly without relying on external installation equipment.

[0025] Preferably, the first component is provided with a first internal thread, and the second component is provided with a first external thread that can be threadedly connected to the first internal thread.

Specifically, the washer and the first component are arranged sequentially from the outside to the inside, and the washer is provided with a third internal thread that connects to the second external thread. Along the axial projection direction of the first component, the projection of the hub center hole falls into the projection of the washer, wherein one side of the washer abuts against the plane of the outer edge of the hub center hole. The arrangement of the washer facilitates adjustment of the relative axial height of the third component to the first component.

[0027] Preferably, the second component connects to a transmission block that enables the transmission end to rotate. The transmission block, the second component, and the rotating shaft are coaxially arranged; the transmission block and the second component are either fixedly connected or detachably connected, in this technical solution they are detachably connected; the transmission block and the first component are either fixedly connected or detachably connected, in this technical solution they are detachably connected; the first component contains a second cavity that provides through space for the second component and the transmission block. By setting the transmission block, the transmission end inside the first component can rotate. Because the second cavity has a certain depth, the transmission block allows adjustment of the transmission end at a certain depth, which is beneficial for adjusting and installing the fastening component.

[0028] Preferably, the transmission block includes a first sleeve partially penetrating the first component and a second sleeve coaxially sleeved with the first sleeve. The end of the second sleeve away from the second component is coaxially connected to the shaft. The end of the first sleeve away from the second sleeve is connected to the second component. This allows the rotation of the second component to be transmitted to the shaft via the first and second sleeves, thereby driving the shaft. The second component is located on one side of the fastening component and faces outwards, facilitating user operation.

[0029] Preferably, the first sleeve has a first protrusion arranged radially along the first component, and the second component has one or more first grooves that can engage with the first protrusions. The first grooves are sufficient to drive the first sleeve to rotate circumferentially during the rotation of the second component. In this technical solution, multiple first protrusions are arranged circumferentially at one end of the second component, including two first protrusions that engage with the first grooves. This allows the user to rotate the second component, thereby driving the first sleeve, the second sleeve, and the shaft to rotate, thus adjusting the axial movement position of the disc and the extension of the moving block relative to the first component.

[0030] Preferably, the first sleeve is provided with a second through groove, the cross-sectional shape of the second through groove along the radial direction of the first component is polygonal, and a fitting block is provided at one end of the second sleeve near the first sleeve, which can be fitted with the second through groove. The cross-sectional shape of the fitting block along the radial direction of the first component is a polygon that matches the cross-sectional shape of the second through groove. In this technical solution, both the cross-sectional shape of the second through groove and the fitting block are hexagonal. This allows the first sleeve and the second sleeve to rotate coaxially, enabling the user to drive the shaft to rotate through the second component.

[0031] Preferably, one or more wrenches are provided on the side of the second component away from the first component. In this technical solution, four wrenches are provided; the wrenches facilitate the rotation of the second component, thereby driving the transmission end through the transmission block. This causes the disc of the transmission end to move axially, thereby adjusting the extension of the moving block relative to the first component.

[0032] Preferably, the second sleeve and the shaft are coaxially arranged from the outside to the inside. A protrusion is provided on the outer surface of the shaft along the axial direction of the first component, and a third groove is provided inside the second sleeve to engage with the protrusion. Multiple protrusions are provided along the circumference of the shaft, so that the shaft rotates during the rotation of the second sleeve.

[0033] This technical solution also provides a wheel hub cover mounting structure, including a wheel hub cover and a fastening assembly, wherein the fastening assembly is connected to the wheel hub cover.

[0034] Preferably, the hub cover is disposed in abutment between the first component and the second component along the axial direction of the first component.

[0035] Preferably, the first component is coaxially connected to the third component;

[0036] Along the axial direction of the first component, a hub cover is abutted between the third component and the second component. The hub cover has a mounting through-hole for easy installation, providing passage space for the second component. The outer edge of the mounting through-hole is clamped between the third component and the second component to secure the hub cover. This simple connection method clamps the hub cover between the third and second components. Along the axial direction of the first component, the projections of the second and third components intersect; the first and third components are threaded together. Specifically, the first and third components are coaxially arranged sequentially from the inside out.

[0037] Preferably, along the axial direction of the first component, one or more first slots are provided on the side of the third component close to the second component;

[0038] The second component has one or more second slots; the first slot and the second slot are coaxially arranged and connected to a pin. This synchronizes the second component with the third component; it prevents the second component from loosening under vibration, thus avoiding the wheel cover from coming loose; a wrench passes through the second slot. The locations of the first and second slots do not interfere with the clamping connection between the second and third components and the wheel cover.

[0039] Preferably, the outer surface of the first component is provided with a second external thread, and the interior of the third component is provided with a second internal thread that can be threadedly connected to the second external thread. One or more protrusions are provided on the end of the third component facing the second component to facilitate its rotation. The hub cover is clamped between the protrusions and the end face of the second component facing the third component. The interior of the third component is configured as a third cavity providing through space for the first and second components. The third component is threadedly connected to the first component, and its connection with the first slot, second slot, and pin enhances the stability of the connection between the second and third components.

[0040] Preferably, the hub cover is connected to the cover on the side away from the first component. Along the axial projection direction of the first component, the projection of the second component falls within the projection of the cover. This prevents the fastening components from being exposed to the outside environment.

[0045] A third through hole is provided near the edge of the hub cover, wherein the third through hole is connected to the cavity and the second through hole;

[0046] The third through hole is provided in one or more ways, with multiple through holes arranged circumferentially around the hub cover axis.

[0047] The outer perimeter of the wheel hub cover is equipped with a third through hole and an abutment block, which reduces air turbulence, provides dynamic heat dissipation, reduces wind resistance and improves performance, saves energy and protects the original wheel hub. At the same time, the abutment block on the outer perimeter of the wheel hub cover can wrap the wheel hub and play a role in counter-pressure and anti-loosening fixation.

[0048] Preferably, the hub is provided with a hub center hole;

[0049] Along the radial direction of the first component, the end of the movable block furthest from the center of the first component abuts against the inner surface of the hub's central hole. The contact between the movable block and the inner surface of the hub's central hole connects the fastening assembly for the hub cover to the hub. This connection method is simple and highly stable.

[0050] This application has achieved beneficial technical effects:

[0051] The movable block of this utility model is abutted by the axially moving movable part, thereby extending out of the first component. The movable block extends out of the first component to abut the inner surface of the center hole of the hub, thereby completing the connection between the fastening component and the hub, which facilitates the installation of the hub cover. This connection method is simple, convenient to operate, and occupies little space. Attached Figure Description

Detailed Implementation

[0076] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0077] The technical solution of this utility model will be described in detail below with specific embodiments.

[0078] Reference Figures 1 to 22 As shown, a fastening assembly includes a first component 1, a movable member 2 connected to the first component 1 and axially movable within the first component 1, and a movable block 3 connected to the first component 1 and axially movable, which abuts against the movable member 2 and extends radially to the outside of the first component 1.

[0079] One movable block 3 may be provided, or multiple movable blocks may be provided circumferentially around the axis of the first component 1. The movable part 2 is located inside the first component 1, and the movable block 3 is partially or completely movable inside the first component 1. The movable block 3 is abutted by the axially moving movable part 2, thereby extending out of the first component 1. The movable block 3 extends out of the first component 1 to abut the inner surface of the center hole of the wheel hub, thereby completing the connection between the fastening component and the wheel hub, which facilitates the installation of the wheel hub cover. This connection method is simple, convenient to operate, and occupies little space.

[0080] The movable block 3 is hinged to the first component 1;

[0081] The movable component 2 includes a disc body 21 that can abut against the movable block 3 during axial movement, thereby causing the movable block 3 to rotate around the hinge end, and a transmission end that allows the disc body 21 to move axially within the first component 1.

[0082] The radial end face of the disc 21 is positioned opposite to the side of the moving block 3 near the center of the first component 1.

[0083] The radial end face of the disc 21 abuts against the movable block 3, thereby causing the movable block 3 to rotate around the hinge end and extend out of the first component 1. The hinge end is located between the side of the movable block 3 near the disc 21 and the outer side of the first component 1.

[0084] The first component 1 is provided with a first through groove 11 for accommodating the movable block 3, a hinge hole hinged to the movable block 3, and a first cavity 12 providing space for the axial movement of the movable part 2. The first through groove 11 provides space for the movable block 3 to move; wherein the first through groove 11 is connected to the first cavity 12. The hinge hole is provided on the side wall of the first through groove 11 facing the movable block 3. When the transmission end rotates, the disc 21 coaxially connected to the transmission end moves axially. During the movement of the disc 21, it abuts against the surface of the movable block 3 on the side close to the center of the first component 1, thereby causing the movable block 3 to rotate around the hinge end hinged to the first component 1. Thus, the movable block 3 extends out of the first component and abuts against the inner surface of the center hole of the hub, thereby completing the connection between the fastening component and the hub, which is convenient for installing the hub cover. This connection method is simple and occupies little space.

[0085] The transmission end includes a shaft 22 movably connected to the first component 1 and a guide part for guiding the movement of the disc 21;

[0086] One end of the shaft 22 is threadedly connected to the disc 21. The shaft 22, disc 21, and first component 1 are coaxially arranged. Through the rotation of the shaft 22 and the guiding action of the guide portion on the disc 21, the disc 21 can move along the axial direction of the first component 1 due to the threaded connection between the disc 21 and one end of the shaft 22. After the disc 21, driven by the shaft 22, moves axially a certain distance, it has a self-locking function due to the threaded connection, preventing the disc 21 from moving spontaneously and improving the operational stability of the fastening assembly. After the disc 21 has moved axially a certain distance, the transmission block can be removed.

[0087] The first component 1 is configured as a first cavity 12 that provides space for the axial movement of the disk body 21;

[0088] The guide portion includes a slot 231 and a block 232 that engages with the slot 231;

[0089] The slot 231 is disposed on the disc body 21, and the locking block 232 is disposed on the first cavity 12, or the slot 231 is disposed on the first cavity 12, and the locking block 232 is disposed on the disc body 21. The shaft 22, the disc body 21, and the multiple moving blocks 3 are coaxially arranged; wherein the extending direction of the slot 231 and the locking block 232 is parallel to the axial direction of the first component 1, and the slot 231 and the locking block 232 are arranged in one or more groups; in this technical solution, the slot 231 is disposed on the disc body 21 and the locking block 232 is disposed on the first cavity 12, so that the disc body 21 moves axially under the transmission of the shaft 22. Under the guiding action of the slot 231 and the locking block 232, the disc body 21 moves axially within the first cavity 12 under the transmission of the shaft 22. This structure requires less space and has a simple transmission method;

[0090] The disk body 21 is provided with a first end face 211 that can abut against the movable block in the radial direction;

[0091] The movable block 3 is provided with a contact surface 31 that can abut against the first end face 211, thereby allowing the movable block 3 to rotate around the hinge end. During the axial movement of the disc body 21, the first end face 211 abuts against the contact surface 31, thereby controlling the amount by which the movable block 3 extends relative to the first component 1.

[0092] The contact surface 31 includes a second end surface and a third end surface 312 disposed near the side of the disc body 21, and the second end surface 311 and the third end surface 312 are arranged sequentially along the axial direction of the first component 1.

[0093] The second end face 311 gradually approaches the center of the first component 1 from the third end face 312. When the first end face 211 abuts against the second end face 311, the moving block 3 corresponding to the position of the disc 21 does not extend or extends only partially, but the extension amount cannot effectively abut against the inner surface of the hub center hole, thus facilitating the initial placement of the fastening component into the hub center hole and making it easy to adjust the installation position; when the disc 21 is moved to the point where the first end face 211 abuts against the third end face 312, the moving block 3 corresponding to the position of the disc 21 extends and effectively abuts against the inner surface of the hub center hole. This fastening component has a simple structure, is easy to use, and occupies little space.

[0094] The cross-sectional shape of the contact surface 31 along the axial direction of the first component 1 is one of the following: arc-shaped, straight-line, wavy, or polygonal. In this technical solution, the cross-sectional shape of the contact surface along the axial direction of the first component is arc-shaped.

[0095] The movable component 3 has an abutment block 32 on the side away from the disk body 21. In the initial state, the height of the abutment block 32 is less than the height of the movable block 3 along the axial direction of the first component 1.

[0096] The first component 1 includes a first component 13 and a second component 14 arranged sequentially along the axial direction and connected to each other. The separate arrangement facilitates assembly.

[0097] The second external thread 17 and the first internal thread 15 are respectively provided on the outer surface of the first component 13 and the inner surface of the first component 13.

[0098] Along the axial direction of the first component 1, a plate 131 is provided on the side of the first component 13 near the second component 14, which is movably connected to the shaft 22. The plate 131 is disposed in a first through hole 132 movably connected to the shaft 22. Along the axial direction, on the side of the shaft 22 near the disk 21, a first limiting platform 221 is provided to prevent the shaft 22 from dislodging from the first through hole 132 towards the direction of the second component. The axial projection of the first through hole 132 falls within the projection range of the first limiting platform 221.

[0100] The first component 13 is provided with a first frame 133; the second component 14 is provided with a second frame 141, wherein the first component 13 and the second component 14 are connected to each other, and the space enclosed by the first frame 133 and the second frame 141 forms a first cavity 12.

[0101] The first component 13 is provided with a first movable groove 134; the second component 14 is provided with a second movable groove 142, and the space enclosed by the first movable groove 134 and the second movable groove 142 forms a first through groove 11.

[0103] A connecting part is provided between the first component 13 and the second component 14 to connect the two.

[0104] The connecting part includes a connecting post 144 and a connecting groove 136 that fit together.

[0105] One of the connecting column 144 and the connecting groove 136 is disposed on the first component 13, and the other is disposed on the connecting groove 14. The connecting column 144 and the connecting groove 136 are disposed along the axial direction of the first component 1. Optionally, the positions are such that the first component 13 and the second component 14 can be connected.

[0106] The connecting part further includes a first connecting hole 137 disposed on the first component and a second connecting hole disposed on the second component 14, wherein the first connecting hole 137 and the second connecting hole 145 are coaxially disposed and embedded in the connecting strip.

[0107] The second component 14 has an abutment 146 on the side away from the first component 13 to prevent the disc 21 from detaching from the outside. The abutment 146 is located at the end of the first cavity 12, projected along the axial direction of the first component 1, and the projection of the disc 21 intersects with the projection of the abutment 146. Together with the first limiting platform 131, it defines the position of the disc 21 when the moving block 3 extends out and abuts against the center hole of the hub.

[0108] The fastening assembly also includes a second assembly 4 connected to the first assembly 1. The first assembly 1 and the second assembly 4 are coaxially connected and arranged sequentially from the outside to the inside. Specifically, the first assembly 1 and the second assembly 4 are threaded together. The arrangement of the second assembly 4 can drive the rotation of the transmission end, thereby driving the disc 21 to move axially. The rotation of the second assembly 4 can extend the moving block 3, which facilitates the installation of the fastening assembly and does not require external installation equipment.

[0109] The first component 1 is provided with a first internal thread 15, and the second component 4 is provided with a first external thread 41 that can be threadedly connected to the first internal thread 15. The first component 1 and the second component 4 are threadedly connected, and the second component 4 is partially disposed inside the first component 1, so as to facilitate the rotation of the transmission end through the first component 1.

[0110] A washer 5 is coaxially connected to the outer surface of the first component 1. Specifically, the washer 5 and the first component 1 are arranged sequentially from the outside to the inside, and the washer 5 is provided with a third internal thread 51 that connects to the second external thread. Along the axial projection direction of the first component 1, the projection of the hub center hole falls into the projection of the washer 5, wherein one side of the washer 5 abuts against the plane of the outer edge of the hub center hole. The arrangement of the washer 5 facilitates adjustment of the relative height of the third component to the first component 1 in the axial direction.

[0111] The second component 4 is connected to a transmission block 6 that enables the transmission end to rotate. The transmission block 6, the second component 4, and the rotating shaft 22 are coaxially arranged. The transmission block 6 and the second component 4 are either fixedly connected or detachably connected; in this technical solution, they are detachably connected. The transmission block 6 and the first component 1 are also either fixedly connected or detachably connected; in this technical solution, they are detachably connected. The first component 1 contains a second cavity 16 that provides through space for the second component 4 and the transmission block 6. By setting the transmission block 6, the transmission end inside the first component 1 can rotate. Because the second cavity 16 has a certain depth, the transmission block 6 allows for adjustment of the transmission end at a certain depth, facilitating the adjustment and installation of the fastening components.

[0112] The transmission block 6 includes a first sleeve 61 partially penetrating the first component 1 and a second sleeve 62 coaxially sleeved with the first sleeve 61. The end of the second sleeve 62 away from the second component 4 is coaxially connected to the shaft 22. The end of the first sleeve 61 away from the second sleeve 62 is connected to the second component 4. The rotation of the second component 4 is transmitted to the shaft 22 through the first sleeve 61 and the second sleeve 62, thereby driving the shaft 22. The second component 4 is located on the fastening component side and faces outward, making it convenient for the user to operate.

[0113] The first sleeve 61 has a first protrusion 611 radially arranged along the first component 1, and the second component 4 has one or more first grooves 42 that can engage with the first protrusions 611. The first grooves 42 are sufficient to drive the first sleeve 61 to rotate circumferentially during the rotation of the second component 4. In this technical solution, multiple first protrusions 611 are arranged circumferentially at one end of the second component 4, including two first protrusions 611, which engage with the first grooves 42. This allows the user to rotate the second component 4 to drive the first sleeve 61, the second sleeve 62, and the shaft 22 to rotate, thereby adjusting the axial movement position of the disc 21 and the extension of the moving block 3 relative to the first component 1.

[0114] The first sleeve 61 is provided with a second through groove 612. The cross-sectional shape of the second through groove 612 along the radial direction of the first component 1 is polygonal. The second sleeve 62 has a fitting block 621 near one end of the first sleeve 61, which can engage with the second through groove 612. The cross-sectional shape of the fitting block 621 along the radial direction of the first component 1 is a polygon that matches the cross-sectional shape of the second through groove 612. In this technical solution, both the second through groove 612 and the fitting block 621 have hexagonal cross-sectional shapes. This allows the first sleeve 61 and the second sleeve 62 to rotate coaxially, enabling the user to rotate the shaft 21 via the second component 4.

[0115] One or more wrenches 43 are provided on the side of the second component 4 away from the first component 1. In this technical solution, four wrenches are provided; the wrenches 43 facilitate the rotation of the second component 4, thereby driving the transmission end through the transmission block 6. This causes the disc 21 of the transmission end to move axially, thereby adjusting the extension of the moving block 3 relative to the first component 1.

[0116] The second sleeve 62 and the shaft 22 are coaxially arranged from the outside to the inside. The outer surface of the shaft 22 is provided with a protrusion 222 along the axial direction of the first component 1. The second sleeve 62 is provided with a third groove 622 that can be fitted with the protrusion 222. Multiple protrusions are arranged along the circumference of the shaft, so that the shaft rotates during the rotation of the second sleeve.

[0117] This technical solution also provides a wheel hub cover mounting structure, including a wheel hub cover and a fastening assembly, wherein the fastening assembly is connected to the wheel hub cover 7.

[0118] Along the axial direction of the first component 1, the hub cover 7 is disposed in contact with the second component 4.

[0119] The first component 1 is coaxially connected to the third component 8;

[0120] Along the axial direction of the first component 1, a hub cover 7 is abutted between the third component 8 and the second component 4. The hub cover 7 has a mounting through hole 71 for easy installation, providing passage space for the second component 4. The outer edge of the mounting through hole is clamped between the third component 8 and the second component 4 to fix the hub cover 7. This simple connection method clamps the hub cover 7 between the third component 8 and the second component 4. Along the axial direction of the first component 1, the projections of the second component 4 and the third component 8 intersect each other; the first component 1 and the third component 8 are threaded together. Specifically, the first component 1 and the third component 8 are coaxially arranged sequentially from the inside out.

[0121] Along the axial direction of the first component 1, one or more first slots 81 are provided on the side of the third component 8 close to the second component 4;

[0122] The second component 4 is provided with one or more second slots 44; the first slot 81 and the second slot 44 are coaxially arranged and connected to a pin 45. This synchronizes the second component 4 with the third component 8; it ensures that the second component 4 will not loosen under vibration, thus preventing the wheel cover 7 from becoming loose; the second slot 44 passes through a wrench 43. The locations of the first slot 81 and the second slot 44 do not interfere with the connection positions of the second component 4 and the third component 8 for clamping the wheel cover 7.

[0123] The first component 1 has a second external thread 17 on its outer surface, and the third component 8 has a second internal thread 82 that can be threadedly connected to the second external thread 17. One or more protrusions 83 are provided on the end of the third component 8 facing the second component 4 to facilitate its rotation. The hub cover 7 is clamped between the protrusions 83 and the end face of the second component 4 facing the third component 8. The interior of the third component 8 is configured as a third cavity 84 providing through space for the first component 1 and the second component 4. The third component 8 is threadedly connected to the first component 1, and its connection with the first slot 81, the second slot 44, and the pin 45 further enhances the stability of the connection between the second component 4 and the third component 8.

[0124] The hub cover 7 is connected to the cover 72 on the side away from the first component 1. Along the axial projection direction of the first component 1, the projection of the second component 4 falls within the projection of the cover. This prevents the fastening components from being exposed to the outside environment.

[0125] This technical solution also provides a wheel hub assembly, including a wheel hub 9 and a wheel hub cover mounting structure connected to the wheel hub 9. An abutment block 74 is provided along the edge of the wheel hub cover 7, and the abutment block 74 extends axially along the wheel hub cover 7.

[0126] Along the radial direction of the hub 9, the inner side of the abutting block 74 abuts against the outer edge of the hub 9, wherein the outer side of the hub 9 is provided with an abutting part 94 that abuts against the inner side of the abutting block 74;

[0127] A cavity 95 is provided between the hub cover 7 and the hub 9 along the axial direction of the hub 9;

[0128] The hub 9 is provided with multiple second through holes 96;

[0129] The hub cover 7 is provided with a third through hole 75 near its edge, wherein the third through hole 75 is connected to the cavity 95 and the second through hole 96;

[0130] The third through hole 75 is provided with one or more holes, and multiple holes are provided circumferentially with the hub cover axis as the center.

[0131] The wheel hub cover 7 is surrounded by a third through-hole 75 and an abutment block 74. These components reduce air turbulence, provide dynamic heat dissipation, reduce wind resistance, improve performance, save energy, and protect the original wheel hub. The side of the wheel hub cover 7 away from the wheel hub 9 has a smooth surface, which creates a more controllable airflow environment. The airflow channels designed within this controllable environment enhance heat dissipation and ensure efficient operation, preventing failure due to surrounding turbulence. The efficient heat dissipation channel, the third through-hole 75, introduces and exits airflow in an orderly manner, reducing air turbulence within the wheel well and further contributing to lower wind resistance. Simultaneously, the abutment block 74 around the wheel hub cover 7 provides edge support to the wheel hub, acting as a counter-pressure and anti-loosening fixation mechanism. The abutment block 74 exerts a reverse supporting force on the wheel hub 9, utilizing its elastic deformation and rebound to generate a reverse locking force, thus preventing the wheel hub cover 7 from loosening under vibration.

[0132] The hub 9 is provided with a hub center hole 90;

[0133] Along the radial direction of the first component 1, the end of the movable block 3 furthest from the center of the first component 1 abuts against the inner surface of the hub center hole 90. The contact between the movable block 3 and the inner surface of the hub center hole 90 connects the fastening assembly of the hub cover 7 to the hub 9. This connection method is simple and highly stable.

[0134] A shock-absorbing ring 73 is provided between the radial outer peripheral edge of the hub cover and the outer side surface of the hub. The hub cover 7, the shock-absorbing ring 73, and the hub 9 are arranged sequentially along the radial direction of the first component.

[0135] The inner surface of the wheel hub is defined as A, and the outer surface of the wheel hub as B. The wheel hub in this technical solution is used in vehicles, especially automobiles.

[0136] There is a height difference between the center hole 90 of the wheel hub and the plane containing the outer edge of the outer side of the wheel hub. In this technical solution, the fastening assembly is connected to the first, second, and third components via threads. This allows the fastening assembly connecting the wheel hub cover to be adjusted in height relative to the center hole of the wheel hub by screwing. The second and third components are both located away from the moving block, thus maintaining a certain distance between the position where the wheel hub cover is limited and the position where the moving block abuts against the center hole of the wheel hub. The position of the wheel hub cover relative to the moving block can be adjusted by the axial position of the second and third components relative to the first component. This allows the wheel hub cover to adapt to different heights of the center hole and the outer diameter surface of different wheel hubs, thus accommodating different installation heights. This improves the adaptability to installation heights. Furthermore, the screwing method allows the abutment block to be installed against the inner surface of the center hole of the wheel hub, enabling tool-free installation and removal.

[0137] By twisting the first sleeve, the shaft is rotated, causing the disc to move axially. This pushes the moving block apart from the center of the first component, causing it to abut against the inner surface of the hub's center hole, thus achieving a reinforcing effect.

[0138] During installation, place the washer and then assemble the third component with the first component, which has internal and external threads, to adjust to the appropriate height. After placing the wheel cover on the third component, tighten it with the second component to clamp and fix the wheel cover. Use a pin to connect the second and third components. The second component is threaded to the first component, which ensures that the second component will not loosen even under vibration, thus preventing the wheel cover from coming loose. The operation is simple and makes the assembly between the wheel cover and the wheel hub very reliable after installation.
