[0018] Embodiment 1:

[0019] As Figure 1 - Figure 2As shown in the figure, this embodiment provides a brake shoe with easy heat dissipation, which includes a brake shoe body 1. The brake shoe body 1 includes an arc-shaped brake main board 2, two mounting vertical plates 3 symmetrically fixed at the bottom of the arc-shaped brake main board 2 in the front and back, and an arc-shaped brake pad 6 fixed at the top of the arc-shaped brake main board 2. A heat dissipation cavity 8 is formed between the two mounting vertical plates 3 and the arc-shaped brake main board 2. A first heat dissipation component 11 is provided on the arc-shaped brake main board 2, and a second heat dissipation component 12 is provided in the heat dissipation cavity 8. Both the first heat dissipation component 11 and the second heat dissipation component 12 play a role in dissipating heat from the brake shoe body.

[0020] The brake shoe with easy heat dissipation includes a brake shoe body 1. The brake shoe body 1 includes an arc-shaped brake main board 2. Two mounting vertical plates 3 are symmetrically fixed at the bottom of the arc-shaped brake main board 2 in the front and back. An arc-shaped brake pad 6 is fixed at the top of the arc-shaped brake main board 2. A heat dissipation cavity 8 is formed between the two mounting vertical plates 3 and the arc-shaped brake main board 2. A first heat dissipation component 11 is provided on the arc-shaped brake main board 2, and a second heat dissipation component 12 is provided in the heat dissipation cavity 8. Both the first heat dissipation component 11 and the second heat dissipation component 12 play a role in dissipating heat from the brake shoe body. By providing the first heat dissipation component 11 and the second heat dissipation component 12, the heat absorbed from the arc-shaped brake main board 2 can be transferred outward, so that the arc-shaped brake main board 2 continuously and rapidly dissipates heat, thereby quickly reducing the temperature of the brake shoe body 1.

[0021] Furthermore, the heat dissipation component includes a plurality of square heat dissipation through holes 4 uniformly formed on the arc-shaped brake main board 2. The square heat dissipation through holes 4 are arranged in the front-back direction, and the plurality of square heat dissipation through holes 4 are arranged in a staggered manner.

[0022] The heat dissipation component includes a plurality of square heat dissipation through holes 4 uniformly formed on the arc-shaped brake main board 2, with the square heat dissipation through holes 4 arranged in the front-back direction and the plurality of square heat dissipation through holes 4 arranged in a staggered manner. The brake shoe body 1 can dissipate heat through the square heat dissipation through holes 4. The square heat dissipation through holes 4 increase the contact area between the brake shoe body 1 and the outside air, thereby improving the heat dissipation efficiency of the brake shoe body 1.

[0023] Furthermore, a transverse heat dissipation tube 5 is fixedly provided in the square heat dissipation through hole 4. The brake shoe body 1 can transfer heat to the transverse heat dissipation tube 5 through the square heat dissipation through hole 4. The transverse heat dissipation tube 5 has better heat conduction ability, so that the heat on the brake shoe body 1 can be quickly dissipated, enabling the brake shoe body 1 to better dissipate heat and cool down, and improving the performance of the brake shoe body 1.

[0024] Furthermore, the second heat dissipation component 12 includes a plurality of longitudinal heat dissipation tubes 9 located in the heat dissipation cavity 8 and fixedly arranged at the bottom of the arc-shaped braking main board 2, and a plurality of heat dissipation fins 10 fixedly arranged on the longitudinal heat dissipation tubes 9. The plurality of heat dissipation fins 10 are staggered. The heat absorbed by the longitudinal heat dissipation tubes 9 from the braking body is transferred to the heat dissipation space, and the longitudinal heat dissipation tubes 9 are in contact with the external air, so that the absorbed heat is quickly dissipated, thereby enabling the brake shoe body 1 to continuously and quickly dissipate heat. All the heat dissipation fins 10 can be in contact with the air, thereby increasing the contact area and accelerating the speed of heat dissipation.

[0025] Furthermore, a plurality of wear-resistant particles 7 are uniformly and fixedly arranged on the top of the arc-shaped brake pad 6. The arrangement of the wear-resistant particles 7 can improve the wear resistance efficiency of the brake shoe body 1. Therefore, compared with the prior art, the technical problems of poor wear resistance effect, few functions and reduced practicability of the existing brake shoe are solved.
