[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The rear axle brake drum removal tool according to an embodiment of the utility model will be described below with reference to the accompanying drawings.

[0023] The rear axle brake drum disassembly tool provided by the embodiment of the utility model is mainly used for disassembling the brake drum after tightening the fixing parts during the assembly of a new car (or during subsequent maintenance), and has the advantages of easy operation and high disassembly efficiency.

[0024] like Figure 1-Figure 4 As shown, the rear axle brake drum removal tool of the embodiment of the utility model may include: a support mechanism 1 and a rod body 21.

[0025] The support mechanism 1 is sleeved on the outside of the rod body 21 , and the support mechanism 1 includes a plate body 11 , a plurality of pull rods 12 and a connecting assembly 13 .

[0026] The plate body 11 is arranged in an annular structure, and a plurality of positioning slots 110 are opened on the plate body 11 . One ends of the plurality of tie rods 12 are connected to the plate body 11 , and the other ends of the plurality of tie rods 12 are connected to the connection assembly 13 .

[0027] A spiral guide rail 22 is provided on the outer wall of the rod body 21 , and the connecting assembly 13 is arranged outside the spiral guide rail 22 .

[0028] Specifically, the disassembly tool is pressed against the outer mounting surface of the brake drum (brake pot) to be disassembled, so that the screw on the outer mounting surface of the brake drum (brake pot) to be disassembled is inserted into the interior of the positioning groove 110. Relevant technicians (for example, workers) can use the fixing part (nut) between the brake drum and the rear axle half shaft to connect it with the screw, thereby fixing the disassembly tool on the outer mounting surface of the brake drum to be disassembled.

[0029] The worker uses a tool to rotate the rod body 21, and the connecting assembly 13 and the rod body 21 are displaced, so that one end of the rod body 21 contacts the end of the rear axle half shaft. The worker continues to rotate the rod body 21, and the connecting assembly 13 continues to be displaced with the rod body 21. Under the action of the pull rod 12, the connecting assembly 13 drives the plate body 11 to move, and the plate body 11 drives the brake drum to move, so that the conical contact surface of the brake drum is separated from the conical contact surface of the rear axle half shaft, thereby completing the disassembly of the brake drum.

[0030] The disassembly tool can avoid damage to the brake drum, is easy to operate, and improves work efficiency.

[0031] As a possible situation, there is no screw on the brake drum of some models, but there are bolt holes that cooperate with the screw. Relevant technicians (for example, workers) can use external bolts to fix the disassembly tool on the outer mounting surface of the brake drum to be disassembled.

[0032] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, the connection assembly 13 may include a cover 131 and a nut 133 .

[0033] The cover body 131 is connected to the plurality of pull rods 12 , a hexagonal groove 132 is provided on the cover body 131 , a nut 133 is located inside the hexagonal groove 132 , and the nut 133 is threadedly connected to the spiral guide rail 22 .

[0034] It is understandable that, under the limiting effect of the hexagonal groove 132 , when a worker rotates the rod body 21 , the cover body 131 and the nut 133 move simultaneously.

[0035] Specifically, after long-term use, the worker can rotate the nut 133 to separate the nut 133 from the rod body 21, and then remove the rod body 21. The worker can repair and maintain the rod body 21 and replace the nut 133, thereby extending the service life of the disassembly tool.

[0036] In one embodiment of the present invention, Figure 2 As shown, the positioning slot 110 is arranged in a straight slot structure.

[0037] It can be understood that by configuring the positioning through slot 110 to be a straight slot structure, the disassembly tool can be applied to various types of brake drums, thereby expanding the application scope of the disassembly tool.

[0038] In one embodiment of the present invention, Figure 3 As shown, a rotating rod 31 is provided at one end of the rod body 21 , and a top rod 32 is rotatably connected to one end of the rotating rod 31 .

[0039] In one embodiment of the present invention, Figure 3 As shown, a protective pad 33 is provided at one end of the push rod 32 .

[0040] It should be noted that one end of the rotating rod 31 described in this embodiment may be connected to the top rod 32 via a bearing.

[0041] It can be understood that during the rotation of the rod body 21, since one end of the rotating rod 31 is rotationally connected to the push rod 32, the push rod 32 remains stationary, and no relative sliding occurs between the end of the push rod 32 and the end of the rear axle half-shaft, thereby preventing the end of the push rod 32 from damaging the end of the rear axle half-shaft. The protective pad 33 can play a role of buffering protection, which can further prevent the end of the push rod 32 from damaging the end of the rear axle half-shaft.

[0042] In one embodiment of the present invention, Figure 3 As shown, a through hole 41 is formed on the rod body 21 .

[0043] In one embodiment of the present invention, Figure 3 As shown, a rotating member 42 is provided at one end of the rod body 21 .

[0044] It should be noted that the rotating member 42 described in this embodiment has a hexagonal structure.

[0045] Specifically, workers can insert a rod-shaped tool into the through hole 41 and then rotate the rod body 21; workers can also rotate the rod body 21 with a wrench. The two rotating methods improve the convenience of workers when using the disassembly tool.

[0046] In summary, the rear axle brake drum disassembly tool of the present invention uses the end of the rear axle half shaft as a support point, rotates the rod body, causes displacement between the rod body and the support mechanism, and thus removes the brake drum, which can avoid damage to the brake drum, is easy to operate, and improves work efficiency.
