The outer wall of the liquid-cooled brake disc body 1 is symmetrically provided with heat dissipation holes 10 in an annular circumferential array. One end of the liquid-cooled brake disc body 1 is provided with a mounting groove 2. A mounting plate 3 is threadedly connected inside the mounting groove 2. A mounting seat 4 is fixedly connected to one end of the mounting plate 3. The mounting seat 4 extends into the liquid-cooled brake disc body 1. A brake drum 6 is movably connected to one end of the liquid-cooled brake disc body 1 away from the mounting plate 3. A positioning block 7 is symmetrically fixedly connected to the outer wall of the brake drum 6 in an annular circumferential array. A first positioning component 11 is installed inside the positioning block 7. A positioning groove 5 is symmetrically provided at one end of the mounting seat 4 in an annular array. A second positioning component 13 is symmetrically installed on the inner wall of the positioning groove 5.

[0022] The first positioning component 11 includes a cavity 111, a first return spring 112, a movable plate 113, and a locking block 114. The positioning block 7 has a cavity 111 inside. One end of the cavity 111 is fixedly connected to the first return spring 112, and the other end of the first return spring 112 is fixedly connected to the movable plate 113. The movable plate 113 is slidably connected to the cavity 111. The locking block 114 is fixedly connected to the end of the movable plate 113 away from the first return spring 112. The end of the locking block 114 away from the first return spring 112 extends beyond the upper end of the positioning block 7. Both ends of the locking block 114 are symmetrically designed with bevels. A locking groove is formed at one end of the positioning groove 5. 12. The positioning block 7 is inserted into the positioning groove 5, and the locking groove 12 is snapped into the locking block 114. The brake drum 6 and the liquid-cooled brake disc body 1 are combined, so that the brake drum 6 is inserted into the liquid-cooled brake disc body 1. At the same time, the positioning block 7 is inserted into the positioning groove 5. During the insertion process, the squeezing force applies pressure to one end of the inclined surface of the locking block 114, so that the locking block 114 drives the moving plate 113 to compress the first return spring 112. The locking block 114 retracts into the cavity 111. Then, when the locking block 114 moves to the locking groove 12, the first return spring 112 returns to its original position, and the moving plate 113 rebounds, causing the locking block 114 to pop out. The locking block 114 is then snapped into and fixed with the locking groove 12.

[0023] refer to Figure 5 The second positioning component 13 includes an internal hole 131, a second return spring 132, and a positioning post 133. The positioning groove 5 has internal holes 131 symmetrically arranged at both ends. One end of each internal hole 131 is fixedly connected to the second return spring 132, and the other end of the second return spring 132 is fixedly connected to the positioning post 133. The positioning post 133 is slidably connected to the internal hole 131. The end of the positioning post 133 away from the second return spring 132 extends into the positioning groove 5 and is designed as an arc-shaped surface. The positioning block 7 has positioning holes 14 symmetrically arranged at both ends. Positioning pin 133 is snapped into place, merging brake drum 6 with liquid-cooled brake disc body 1, so that brake drum 6 is inserted into liquid-cooled brake disc body 1, and positioning block 7 is inserted into positioning groove 5. During insertion, the squeezing force applies pressure to the arc-shaped surface of one end of positioning pin 133, so that positioning pin 133 compresses the second return spring 132, and positioning pin 133 retracts into the inner hole 131. Then, when positioning pin 133 moves to positioning hole 14, the second return spring 132 returns to its original position, positioning pin 133 pops out, and positioning pin 133 is snapped into and fixed with positioning hole 14.

[0024] refer to Figures 2 to 3A mounting ring 15 is fixedly connected to the outer wall of the brake drum 6. A fixing groove 16 is provided at the end of the liquid-cooled brake disc body 1 away from the mounting groove 2. The mounting ring 15 is inserted into the fixing groove 16. Threaded holes 17 are symmetrically provided at one end of the mounting ring 15 and the inside end of the fixing groove 16 through a circular circumferential array. The threaded holes 17 on the mounting ring 15 are aligned with the threaded holes 17 inside the fixing groove 16. The threaded holes 17 are threadedly connected to the fixing bolts 18. The brake drum 6 and the liquid-cooled brake disc body 1 are combined, so that the brake drum 6 is inserted into the liquid-cooled brake disc body 1, and the mounting ring 15 is inserted into the fixing groove 16. At the same time, the threaded holes 17 on the mounting ring 15 are aligned with the threaded holes 17 inside the fixing groove 16. Then, the fixing bolts 18 are threadedly connected to the threaded holes 17.

[0025] refer to Figures 2 to 3 The mounting ring 15 is fixedly connected to a fixing post 8 at one end near the liquid-cooled brake disc body 1 via a circular circumferential array. The fixing groove 16 has fixing holes 9 symmetrically opened at one end via a circular circumferential array. The fixing holes 9 and the fixing posts 8 are inserted into each other. The brake drum 6 and the liquid-cooled brake disc body 1 are combined so that the brake drum 6 is inserted into the liquid-cooled brake disc body 1. The mounting ring 15 is inserted into the fixing groove 16, and the fixing post 8 is inserted into the fixing groove 16 for insertion and fixation.

[0026] Operating principle and advantages: First, the brake drum 6 is combined with the liquid-cooled brake disc body 1, so that the brake drum 6 is inserted into the liquid-cooled brake disc body 1. At the same time, the positioning block 7 is inserted into the positioning groove 5. During the insertion process, the squeezing force applies pressure to one end of the locking block 114, causing the locking block 114 to drive the moving plate 113 to compress the first return spring 112. The locking block 114 retracts into the cavity 111. Then, when the locking block 114 moves to the locking groove 12, the first return spring 112 returns to its original position, and the moving plate 113 rebounds, causing the locking block 114 to spring back. The locking block 114 is engaged and fixed with the locking groove 12. At the same time, the extrusion force is applied to the arc-shaped surface of one end of the positioning post 133, causing the positioning post 133 to compress the second return spring 132. The positioning post 133 retracts into the inner hole 131. Then, when the positioning post 133 moves to the positioning hole 14, the second return spring 132 returns to its original position, the positioning post 133 pops out, and the positioning post 133 is engaged and fixed with the positioning hole 14. Then, the fixing bolt 18 is threadedly connected to the fixing groove 16 and the threaded hole 17 of the mounting ring 15 to complete the installation of the brake drum 6.

[0027] This invention ensures that the brake disc and brake drum 6 are in the correct position during installation, avoiding deviations caused by improper installation. It helps reduce shaking and deviations during braking, improves the stability and reliability of braking, and enhances the overall structural stability of the braking system. It also helps prevent the brake disc or brake drum 6 from deforming or being damaged due to excessive force during braking.
