[0028] Embodiment
[0029] Referring to Figure 1 and 3 shown, in an embodiment of the present utility model, a hub cap installation assembly includes five screws 4 for locking the hub 1 and the hub shaft. The five screws 4 are evenly distributed on the same circle on the front surface of the hub 1. Five screw holes are annularly arranged on the front surface of the hub 1. The bolts pass through the screw holes and are threadedly connected to the screws. (The front surface of the hub 1 refers to the outer surface of the hub 1 along the vehicle body width direction). The installation assembly further includes,
[0030] The hubcap body 2 made of steel is arranged at the center of the front side of the hub 1 and its inner side abuts against one end of the screw 4 (the inner side of the hubcap body 2 refers to the inner surface of the hubcap body 2 along the vehicle body width direction). There are connecting seats 3 corresponding to the five screws 4 on the inner side of the hubcap body 2. The connecting seat 3 includes three feet 31 fixedly connected to the hubcap body 2. The three feet 31 are annularly arrayed along the circumferential direction of the screw 4. The number of the feet 31 can also be set to four, five or even more according to actual needs. The screw 4 is pressed between the three feet 31, and the three feet 31 respectively surround the screw 4 from three different directions to realize the first limit of the hubcap body 2. There is a convex part 36 on the inner side of the foot 31. The inner side of the foot 31 refers to the surface of the foot 31 adjacent to the screw 4.
[0031] The gasket 37 made of stainless steel is coaxially connected with the screw 4 and has a diameter larger than that of the screw 4. The convex part 36 is located at the end of the screw 4 away from the hubcap body 2, and the convex part 36 abuts against / presses the gasket 37 towards the hubcap body 2, thereby pressing the bolt on the hubcap body 2 to realize the second limit of the screw 4.
[0032] Refer to Figure 3 As shown, the connecting seat 3 further includes a clamping member 35. The clamping member 35 is arranged around the periphery of the three feet 31 and applies pressure to the three feet 31 towards the center of the connecting seat 3, aiming to make the three feet 31 and the convex part 36 of the feet 31 fit more closely to the screw 4 to prevent the screw 4 from detaching from the connecting seat 3 due to the vibration of the wheel.
[0033] Refer to Figure 7 As shown, the clamping member 35 is set as a snap ring. The variable elasticity of the snap ring is used to quickly put the snap ring on the outer sides of the three feet 31. Further, the snap ring is composed of a metal ring 351 and a spring 352. There is a break 371 at one place of the metal ring 351. The two sides of the break 371 are respectively the head and the tail of the metal ring 351. The two ends of the spring 352 are respectively fixedly connected to the head and the tail. In other embodiments, the clamping member 35 can also be set as a hoop, and the advantage of the hoop is that the clamping force is constant.
[0034] Refer to Figure 4 As shown, in order to position the clamping member 35 and prevent the clamping member 35 from detaching from the connecting seat 3, a limiting block 32 is arranged on the outer side of the foot 31. The limiting block 32 is arranged on both sides of the clamping member 35 along its axial direction. The limiting block 32 can limit the clamping member 35 from sliding along the clamping member.
[0035] Refer to Figure 3 and 5As shown, in order to stably sleeve the gasket 37 on the screw 4 and prevent the gasket 37 from sliding relative to the screw 4, a circumferential concave portion 41 is radially recessed on the side surface of the screw 4. The circumferential concave portion 41 matches the gasket, and the gasket 37 is coaxially sleeved outside the circumferential concave portion 41.
[0036] Referring to Figure 6 As shown, the gasket 37 is provided as an annular gasket 37, and the annular gasket 37 is provided with a notch 371. By stretching / squeezing the gasket 37, the notch 371 can be widened / narrowed, which is convenient for assembling the annular gasket 37 on the screw 4 or disassembling the gasket 37.
[0037] Referring to Figure 4 As shown, during the process of the screw 4 locking the wheel hub 1, a vibration feeling is generated. Four reinforcing ribs 33 are further provided on the outer side of the clamping foot 31 to improve the stability of the clamping foot 31. The four reinforcing ribs 33 can also be used as the limiting blocks 32 on one side of the clamping member 35. Further, the adjacent clamping feet 31 are fixedly connected through a connecting portion 34, so that the three clamping feet 31 are connected into a whole, further improving the clamping force of the connecting seat.
[0038] Referring to Figure 2 As shown, five of the connecting seats 3 are annularly arranged inside the wheel hub cover body 2. When the wheel hub cover body 2 is aligned with the center of the wheel hub 1, the five connecting seats 3 are arranged in one-to-one correspondence with the five screw holes.
[0039] Referring to Figure 3 As shown, in order to enable the convex portion 36 to adaptively press against the gasket 37 under different clamping forces of the clamping foot 31, the convex portion 36 is provided with an inclined surface 361, and the convex portion 36 abuts against the gasket 37 through the inclined surface 361.
[0040] Referring to Figure 3 As shown, three support blocks 21 are convexly provided inside the connecting seat 3 of the wheel hub cover. The three support blocks 21 are all arranged in an arc shape and are annularly arranged. The three support blocks 21 abut against the screw 4 to separate the screw 4 from the wheel hub cover body 2.
[0041] The working principle of the wheel hub cover installation assembly of the present utility model is:
[0042] First, put the gasket 37 on the annular recess 41 of the screw 4. Then, press the five screws 4 with the gasket into the five connecting seats 3 respectively, so that the three clamping feet 31 hold the screw 4 tightly from three directions, and the convex part 36 of the clamping foot 31 presses the gasket 37 tightly towards the hub cap body 2. Next, put the clamping member 35 around the outside of the three clamping feet 31, so that the three clamping feet 31 hold the screw 4 more tightly, realizing the fixed connection between the screw 4 and the hub cap. Finally, align the hub cap with the center of the hub 1, ensure that the five connecting seats 3 are aligned with the five screw holes on the hub 1, and then lock the five screws 4 on the hub 1 through five bolts to realize the assembly of the hub 1 and the hub cap.
[0043] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description.
