In the figure: 1. a drum body; 2. a mounting surface; 3. a reinforcing surface; 201. mounting holes; 301. a reinforcing ring; 401. an arc-shaped groove; 402. an arc-shaped arrow groove.
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: as shown in connection with fig. 1-3, comprises a drum body 1; a mounting surface 2 is arranged on one side of the upper part of the drum body 1; a reinforcing surface 3 is arranged on the other side of the upper part of the drum body 1; a working surface 4 is arranged between the mounting surface 2 and the reinforcing surface 3; the mounting surface 2, the reinforcing surface 3 and the working surface 4 are integrally cast; arc-shaped grooves 401 are uniformly formed in the periphery of the upper part of the outer surface of the working surface 4; arc-shaped arrow grooves 402 are uniformly formed on the upper periphery of the inner surface of the working surface 4; the arc-shaped arrow groove 402 is low outside and high inside; the mounting surface 2 is integrally in a trapezoidal shape; mounting holes 201 are uniformly formed in the periphery of the upper part of the mounting surface 2; a reinforcing ring 301 is arranged at the upper part of the reinforcing surface 3; the reinforcing ring 301 is connected with the drum body 1 through bolts; the material of the reinforcing ring 301 is hard alloy.
When in use, as shown in fig. 1-3, when a user uses the brake drum produced by the utility model, the upper part of the reinforced surface 3 is provided with the reinforced ring 301 to promote the use of the traditional brake drum, because the material is gray cast iron, the metallographic change is often generated at high temperature, so that the traditional brake drum is easy to crack and lose efficacy, the reinforced ring 301 is made of alloy material and is fixedly connected with the drum body 1 through bolts, so that the integral performance of braking is promoted, the brake drum is worn along with an incoming sheet and impurities in the air are deposited inside the brake drum, so that noise is generated in the braking process, and the braking effect is reduced, therefore, the inner periphery of the brake drum is uniformly provided with arc grooves 402 with high inner parts and low outer parts to store and clean the impurities inside the brake drum, the outer surface of the working surface 4 is also uniformly provided with arc grooves 401, when the brake drum sprays cooling water to cool down, can delay the loss rate of cooling water through arc arrow groove 402 to promote the cooling effect, and reduced the loss rate of cooling water.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
