Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: referring to fig. 1-2, a novel automobile brake drum comprises a drum body 1, wherein a mounting plate 2 is arranged on one side of the drum body 1, and a mounting hole 8 is formed in the mounting plate 2; a heat dissipation port 3 is arranged between the two adjacent mounting plates 2, and the heat dissipation port 3 is communicated with the outside and the inside of the drum body 1; the inner wall of the drum body 1 is provided with a guide surface 10 at the position of the heat dissipation port 3; the drum body 1 is provided with a reinforcing belt 4, a first reinforcing rib 6, a second reinforcing rib 9 and a reinforcing ring 7 on the outer wall, the reinforcing belt 4 is annular and coaxial with the drum body 1, the reinforcing ring 7 is positioned on one side of the drum body 1 far away from the mounting plate 2, and the first reinforcing rib 6 and the second reinforcing rib 9 are perpendicular to the reinforcing belt 4; one end of the first reinforcing rib 6 is connected with the reinforcing belt 4, and the other end of the first reinforcing rib is connected with the reinforcing ring 7; one end of the second reinforcing rib 9 is connected with the mounting plate 2, and the other end of the second reinforcing rib is connected with the reinforcing belt 4; heat dissipation holes 5 are formed in the positions, close to the two ends, of the outer circular surface of the reinforcing belt 4; the inner wall of the drum body 1 is provided with a braking surface 11. The part of mounting panel 2 and drum body 1 connection is provided with the fillet, avoids the phenomenon that the junction produced stress concentration. The number of the first reinforcing ribs 6 and the second reinforcing ribs 9 is the same as that of the mounting plate 2. The thickness of the mounting plate 2 in the axial direction of the brake drum is smaller than that of the heat dissipation port 3 in the axial direction of the brake drum. The guide surface 10 is a conical surface, and the half vertex angle of the conical surface is 5-9 degrees, so that one side of the guide surface 10, which is close to the mounting plate 2, inclines towards the outer wall of the drum body 1, falling objects generated by braking are more easily discharged outwards under the action of centrifugal force, the half vertex angle is too small, the discharge effect is not obvious, and the half vertex angle is too large, so that the wall thickness of the drum body 1 on the side is too small, and the strength is reduced.

Due to the existence of the heat dissipation port 3, both sides of the drum body 1 are communicated with air, so that the air can flow in the drum body 1, and a part of fallen objects can be discharged from one side of the drum body 1 away from the heat dissipation port 3 under the action of air flow, and the structure also enhances the heat dissipation capacity of the brake drum. The heat dissipation holes 5 are located at the positions, close to the edges, of the two sides of the reinforcing belt 4, the middle of the reinforcing belt 4 is of a continuous structure, and the heat dissipation capacity is enhanced while the tensile strength performance of the reinforcing belt 4 is guaranteed.
