[0016] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0017] like Figures 1 to 3 As shown, the present invention provides a tool for disassembling a Sinotruk brake drum, comprising: Arc-shaped component 2, with its two ends extending to form an operating end and a fixed end, respectively; The handle rod 1 is fixedly connected to the operating end of the arc-shaped component 2; The first jaw assembly includes a jaw seat 6 hinged to the middle of the arc-shaped member 2 and a jaw 7 vertically fixed to the jaw seat 6; The second claw assembly includes a claw seat 2 12 fixed to the fixed end of the arc-shaped member 2 and a claw 2 3 vertically fixed to the claw seat 2 12; The extension direction of the second pawl 3 is perpendicular to the axial direction of the brake drum, and the arc-shaped component 2 transmits the pulling force to the first pawl 7 and the second pawl 3 through leverage to disassemble the brake drum.
[0018] In some embodiments, both the claw 7 and the claw seat 6 are provided with a plurality of first through holes, and the two are adjustablely and fixedly connected by a first bolt 8 passing through the first through hole.
[0019] In some embodiments, the fixed end of the arc-shaped member 2 is provided with a U-shaped groove, and the second claw seat 12 is a T-shaped structure with multiple second through holes 9 on its vertical side. The second bolt 13 passes through the second through holes 9 and connects to the U-shaped groove to realize the position adjustment of the second claw seat 12 in the U-shaped groove.
[0020] In some embodiments, the claw seat 6 is hinged to the middle of the arc-shaped member 2 by a pin 5. The pin 5 passes through the through hole in the middle of the arc-shaped member 2 and the circular through hole at the end of the claw seat 6, forming a rotatable connection structure.
[0021] Example 1
[0022] This utility model provides a tool for disassembling a Sinotruk brake drum, which is achieved through the following solution: The arc-shaped component 2 serves as the core load-bearing component, with one end fixed to the handle rod 1 and the other end and middle of the component equipped with a claw assembly. The first claw assembly adapts to brake drums 4 with different curvatures through a hinge design. Claw 7 is vertically fixed to claw seat 6 to provide stable gripping force. The second claw assembly achieves position adjustment through the bolt connection between the T-shaped claw seat 212 and the U-shaped groove, ensuring that it applies force in coordination with the claw 17; When the operator presses down on the handle lever 1, the arc-shaped part 2 converts the pulling force into a uniform force on the two claws, avoiding local deformation.
[0023] Example 2
[0024] Based on Example 1, the through holes of the pawl-7 and the pawl seat-6 are set into three groups. By selecting different hole positions to fix the first bolt 8, the extension length of the pawl-7 can be adjusted to adapt to the edge of the brake drum of different thicknesses.
[0025] This utility model disassembly tool includes an arc-shaped component 2, with a handle rod 1 welded to its operating end and a U-shaped groove formed at its fixed end.

The middle of the arc-shaped component 2 is hinged to the first chuck seat 6 via a pin 5, and the first chuck 7 is vertically fixed to the first chuck seat 6 via a first bolt 8. In use, the two chucks hook onto the edge of the brake drum, and the handle rod 1 is pressed down. The lever action of the arc-shaped component 2 causes the two chucks to apply force simultaneously, peeling off the brake drum. The hinged structure and adjustable chuck design are adaptable to various sizes of brake drums, offering strong versatility. The lever application method reduces operational intensity and avoids damage to components caused by violent impacts. The modular connection structure facilitates maintenance and replacement, reducing operating costs. It can be widely used in heavy-duty vehicle repair scenarios, especially suitable for disassembling brake drums on trucks and vans, significantly improving disassembly efficiency and safety.
