Embodiment
Please refer to shown in Fig. 1 and Fig. 2, that show the concrete structure of the preferred embodiment of the utility model, include brake drum shell 10.
This brake hub shell 10 adopts the mode such as spinning or casting shaping, it is Steel material, the pig iron, Zinc material, carbon fiber or new type plastic material etc., in this brake drum shell 10, there is inner chamber 101, this brake drum shell 10 includes the main part 11 of one-body molded connection successively, joint 12 and assembly department 13, on the outer shroud wall of this main part 11, interval convex is provided with multiple stiffening rib 14, each stiffening rib 14 all axially extends, stiffening rib 14 is obliquely installed along the sense of rotation of brake drum shell 10, to reach better wind effects, each stiffening rib 14 all has one and to keep out the wind face 141, joint between the external annulus face of this keep out the wind face 141 and main part 11 offers intake opening 102, this intake opening 102 communication with cavity 101, this intake opening 102 is inclined hole, so that wind enters in inner chamber 101, and, this intake opening 102 place is provided with filter screen 15, enter in inner chamber 101 with the wind to avoid the impurity such as dust, and this joint 12 sets out air holes 103, and this exhaust vent 103 is communicated with between the external world and inner chamber 101, and this exhaust vent 103 is away from intake opening 102.
And, in the present embodiment, this brake drum shell 10 is steel matter, the inner ring wall upper peripheral edge of main part 11 is placed with multiple brake block 20, gap 201 is formed between adjacent two brake blocks 20, aforementioned intake opening 102 is communicated with gap 201, this brake block 20 is the pig iron or carbon fibre materials, brake block 20 is fixedly connected with the inner ring wall of main part 11 by gluing or screw 30, in the present embodiment, each brake block 20 is all fixedly connected with the inner ring wall of main part 11 by screw 30, specifically, this screw 30 is screwed together fixing through brake block 20 and brake drum shell 10, this brake block 20 is provided with fixed hole 202, accordingly this brake drum shell 10 is provided with screw 104, this screw 30 is screwed together with screw 104 through fixed hole 202, the head 31 of screw 30 is embedded in fixed hole 202 completely, in addition, the outer surface of each brake block 20 is burnishing surface 203, and the shape size of each brake block 20 is identical, and each brake block 20 is arc sheet material.
