Description

Technical Field

[0001] The utility model relates to the technical field of wheel rim bolts, in particular to a drive axle wheel rim bolt which is easy to replace. Background Art

[0002] During the installation and removal of the rims of the drive axles of heavy mining vehicles, press-fit rim bolts and threaded rim bolts are commonly used for connection.

[0003] One end of the press-fit rim bolt is a prototype cut-edge bolt head, which is pressed into the hole of the wheel hub by pressure. Although the press-fit connection is tight, it is difficult to disassemble during the mine tire replacement process, the disassembly workload is large, and the disassembly efficiency is low.

[0004] The threaded rim bolts are provided with external threads and are threadedly connected through nut sleeves. Although the threaded connection method is easy to disassemble and has good tightness after connection, it is prone to thread slippage after multiple disassembly. In this case, the bolts need to be replaced as a whole, but the overall replacement is more troublesome. For this reason, we propose a drive axle rim bolt that is easy to replace.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] As mentioned in the background art, in view of the problem that the prior art bolts are prone to thread slippage after multiple disassembly, the bolts need to be replaced as a whole, which is troublesome. The present invention provides a drive axle rim bolt that is easy to replace.

[0025] Example 1

[0026] Reference Figures 1 to 3 A drive axle rim bolt that is easy to replace, comprising a screw rod 1, the outer portion of which is threadedly connected with a nut 2;

[0027] The right side of screw 1 is fitted with screw 2 3, the outside of screw 2 3 is screwed with nut sleeve 4, the left end of screw 2 3 is provided with screw 3 7, and screw 3 7 is screwed into screw 1;

[0028] Screw 1 is screwed onto the mounting plate 5, nut 2 is in contact with the left side of the mounting plate 5, the mounting plate 5 is connected to the drive axle, and the right side of the mounting plate 5 is sleeved with a rim 6, which has concave holes evenly arranged on the rim 6, and screw 2 3 extends into the concave hole, and the nut sleeve 4 is in contact with the left inner wall of the concave hole.

[0029] In order to improve the stability of screw rod 2 3, a groove 8 is opened on the right side of screw rod 2 3, and bolt heads 9 are provided on both sides of the left inner wall of the groove 8, and screw rod 4 10 is provided at the left end of the bolt head 9. The left end of screw rod 4 10 is screwed to screw rod 2 3 and screw rod 1 1 respectively.

[0030] In order to reduce the difficulty of disassembly, long holes 11 are provided at both ends of the left side of the screw rod 2 3, and the screw rod 4 10 passes through the long holes 11, so that the middle part of the screw rod 4 10 can be smooth, so that it does not need to be fastened to the long holes 11, thereby saving effort when disassembling and assembling the screw rod 4 10.

[0031] In order to facilitate disassembly and assembly, a hexagonal hole 12 is provided at the right end of the bolt head 9 .

[0032] In order to improve the stability of the screw rod 10, the bolt heads 9 on both sides are connected to the anti-loosening assembly.

[0033] Example 2

[0034] Reference Figures 1 to 4 The anti-loosening assembly includes a bearing 13 arranged on the outside of the bolt head 9. The outer ring of the bearing 13 is connected to a mounting ring 14, so that the mounting ring 14 can rotate through the bearing 13 to facilitate alignment with the vertical rod 16. Mounting blocks 15 are provided on both sides of the left inner wall of the groove 8. A vertical rod 16 is vertically penetrated through the mounting block 15. Mounting plates 17 are provided on opposite sides of the vertical rods 16 on both sides. The sides of the vertical rods 16 on both sides away from each other are respectively inserted into the mounting rings 14 on both sides. Springs 18 connected to the mounting blocks 15 are provided on the mounting plates 17 on both sides. The springs 18 apply springs to the mounting plates 17, so that the vertical rod 16 is stably inserted in the mounting ring 14, thereby achieving fixation of the bolt head 9, thereby strengthening the screw four 10.

[0035] The rest of the structure is the same as that of Example 1.

[0036] When the nut sleeve 4 is disassembled multiple times and causes thread slippage, first move the mounting plates 17 on both sides toward the opposite sides to stretch the spring 18, so that the vertical rod 16 can leave the mounting ring 14, and then the screw rod 4 10 can be removed. Then, rotate the screw rod 2 3 to make the screw rod 3 7 leave the screw rod 1 1. There is no need to replace the rim bolt as a whole. Only the screw rod 2 3 and the nut sleeve 4 that have thread slippage need to be replaced. After replacing the screw rod 2 3, install the screw rod 4 10, and then fix the bolt head 9 with the vertical rod 16 to stably fix the screw rod 2 3.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
