Abstract
The invention discloses a safety composite type brake drum with a rapid heat dissipation and anti-burst. The safety composite type brake drum with the rapid heat dissipation and anti-burst comprises a brake drum shell. The brake drum shell is provided with an inner cavity. The brake drum shell comprises a main body part, a connecting part and an installing part, wherein the main body part, the connecting part and the installing part are sequentially connected in an integrated mode. Multiple reinforcing ribs are arranged at intervals on the outer ring wall surface of the main body part in an outward protruding mode. Each reinforcing rib extends in the axial direction, and each reinforcing rib is provided with a wind-proof surface. Air inlets are formed in the joints of the wind-proof surfaces and the outer ring wall surface of the main body part, and the connecting part is provided with air outlets. Accordingly, on one hand, the reinforcing ribs have the structural strengthening effect on safety composite type brake drum, on the other hand, the heat dissipation area is increased, and the heat dissipation effect is improved. Meanwhile, the wind-proof effect can be achieved, air can be driven to form airflow, the airflow flows into the inner cavity, and the heat in the inner cavity is driven out from the air outlets by utilizing the airflow. Therefore the timely heat dissipation or discharge can be achieved, the brake performance of the brake drum can be guaranteed, the burst phenomenon of the brake drum can be prevented, the service life of a product is prolonged, and the potential danger is prevented.

Embodiment
Please refer to shown in Fig. 1 and Fig. 2, that show the concrete structure of the preferred embodiment of the present invention, include brake drum shell 10.
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.
