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.

And, 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.

During use, by assembly department 13, the present invention is installed on Motor Vehicle, Motor Vehicle is in the process run, when needing brake, brake shoe and brake block 20 produce braking friction, make brake block 20 produce heat, a heat part for brake block 20 is passed to brake drum shell 10 and is contacted with air by the outer shroud wall of main part 11 and the outer surface of stiffening rib 14 dispels the heat, now, stiffening rib 14 uses as radiating fin, strengthens radiating effect; And most of heat of brake block 20 is pulled away by air-flow, the forming process of air-flow is as follows: brake drum shell 10 is in the process of rotating, stiffening rib 14 plays windage effect, under the effect in the face of keeping out the wind 141, air forms air-flow, and air-flow enters inner chamber 101 from intake opening 102, discharges after the heat then in air-flow absorption inner chamber 101 from exhaust vent 103, reach the object of being discharged by heat, realize from cooling.

Design focal point of the present invention is: by being provided with stiffening rib on the external annulus of main part, and be equipped with intake opening and exhaust vent, stiffening rib can play the effect of structural strengthening on the one hand to this product, the heat diffusion area of product can be increased on the other hand, improving radiating effect, also can play choke effect simultaneously, make air form air-flow and enter inner chamber, air-flow is utilized to be taken out of from exhaust vent by the heat in inner chamber, thus realize heat being left in time or discharging, ensure the braking quality of brake drum, prevent brake drum from occurring Decrepitation Phenomena, extend the working life of product, and also stop potential safety hazard.

The above, it is only preferred embodiment of the present invention, not technical scope of the present invention is imposed any restrictions, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
