Abstract

The utility model relates to a disc type brake disc structure. A friction section which is formed by superposing a first brake lining, a radiating fin and a second brake lining in sequence is formed at the periphery of the assembly section of the brake disc, and a plurality of radiating ribs with appropriate height are fixedly arranged between the first brake lining and the radiating fin and between the radiating fin and the second brake lining. When the first brake lining and the second brake lining generate high temperature because of braking friction, the high temperature can be discharged through radiating holes formed by the first brake lining, the second brake lining and the radiating ribs, and moreover, the radiating fin can provide effective heat dispersion function. Therefore, the whole brake disc can be quickly cooled and is prevented from deforming because of overheating, and the danger of braking failure caused by the softness of brake shoes due to overheating of the brake disc can be prevented.

Description

Disc brakes dish structure

The utility model relates to a kind of brake disc structure, is a kind of disc brakes dish structure that has the good ventilation gap between the friction position of brake disc specifically.

Press, the brake principle of general vehicle, the main system atwirl kinetic energy of wheel shaft originally converts heat energy to via friction effect, and then the wheel shaft of rotation is stopped, and since wheel shaft at high speed rotating to the process that stops, it makes the brake assemblies of vehicle except need have the heat-resisting demand of certain degree because of the effect of transformation of energy, also need better heat radiating effect between its brake assemblies, because the brake of general vehicle can't be expected and be non-is to be interrupted to carry out, the for example Emergency braking under high-speed travel state and the continuous brake of doing in the descending highway section, all can allow brake assemblies temperature distortion because moment produces high temperature, and because the high temperature that continues can't efficiently radiates heat and produce the softening phenomenon of brake rubber block, and then cause the damage of brake assemblies, can't bring into play original brake function even and cause unexpected generation.

The purpose of this utility model is to provide a kind of disc brakes dish structure that has the good ventilation gap between the friction position of brake disc, makes it have effective thermolysis, prevents that brake disc is because of the overheated danger that produces distortion or cause the softening mistake of brake rubber block to be stopped.

The utility model is to realize like this, a kind of disc brakes dish structure, the periphery that it is characterized in that the assembling position of this brake disc is formed with in regular turn by one first brake lining, the mutually stacked friction position that forms of radiating fin and one second brake lining, and between first brake lining and radiating fin at the position that should rub, and the heat radiation rib that is installed with the suitable height of several tools between this radiating fin and second brake lining, make between first brake lining and radiating fin, and the heat-dissipating space that has draught effect between the radiating fin and second brake lining, when producing high temperature because of the brake friction when first brake lining and second brake lining, its temperature is removed can be by first, second brake lining and heat radiation rib form outside radiation hole row looses, the radiating fin in the middle of more the Yu temperature can being reached and provide an effective thermolysis by radiating fin.

Another feature of the utility model disc brakes dish structure is except making between first brake lining and radiating fin by the heat radiation rib, and have outside the heat-dissipating space of draught effect between the radiating fin and second brake lining, more can use the friction position that first brake lining, radiating fin and second brake lining are combined and become to have suitable structural strength.

Of the present utility modelly one be characterised in that the structure that this assembling position system and first brake lining or second brake lining or radiating fin are formed in one again.

Another being characterised in that on this first brake lining, second brake lining and the radiating fin of the present utility model is formed with some radiation holes, the structure of brake disc can be done the actual increase and decrease that sets quantity of radiating fin according to the permission of actual size form between first brake lining and second brake lining, use to form more efficiently heat radiation function.

The novel advantage of this reality is that this disc brakes dish structure has effective thermolysis, makes the integral brake disc fast cooling to prevent overheating deforming, more can prevent brake disc because overheated and produce that brake rubber block is softening to lose the danger of stopping.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

1, brake disc 11, assembling position 12, friction position 121, first brake lining

122, radiating fin 123, second brake lining 124, heat radiation rib

125, radiation hole

The utility model disc brakes dish structure, the agent structure of its brake disc such as Fig. 1, shown in Figure 2, the main body of brake disc 1 is the disc-shaped structure of a tool great heat radiation effect, its the assembling position 11 interior mating face 112 be able to wheel shaft on wheel hub be fitted to each other, periphery two sides at assembling position 11 are the friction position 12 that forms the frictional resistance effect with brake rubber block, wherein, friction position 12 is in regular turn by one first brake lining 121, radiating fin 122 and one second brake lining, 123 mutually stacked forming, and 122 of first brake lining 121 and radiating fin, and radiating

fin

122 and 123 of second brake linings are installed with the suitably heat radiation rib 124 of height of several tools, its overall structure promptly by the heat radiation rib 124 with first brake lining 121, the friction position 12 that the radiating fin 122 and second brake lining 123 combine and become to have suitable structural strength, and make 122 of first brake lining 121 and radiating fin, and radiating

fin

122 and 123 of second brake linings has suitable radiation hole 125.

Please cooperate simultaneously with reference to shown in Figure 2, since brake disc of the present utility model 1 its in order to form the friction position 12 of frictional resistance effect with brake lining, be by first brake lining 121 and one second, 123 the structural forms in the east of stopping with suitable spacing double team one radiating fin 122, and its mutually stacked structural form that forms first brake lining 121 and one

second brake lining

123 and 122 of radiating fin are linked by some heat radiation ribs 124, and at first brake lining 121,122 of second brake lining 123 and radiating fin are formed with some radiation holes 125, so when its brake disc 1 during in vehicle brake, its high temperature that produces because of friction removes can be by first, second brake lining 121, outside 123 radiation hole 125 rows that form with heat radiation rib 124 loose, more the Yu temperature can be reached middle radiating fin 122 and provide an effective thermolysis by radiating fin 122, use to make two side brake linings surfaces fast cooling, more can prevent brake disc 1 because overheated and produce that brake rubber block is softening to lose the danger of stopping to prevent overheating deforming.Especially, the structure of integral brake disc can be done the actual increase and decrease that sets quantity of sheet dish of loosing according to the permission of actual size form between first brake lining and second brake lining, uses to form more efficiently heat radiation function.

In addition, please cooperate simultaneously with reference to Fig. 2, Fig. 3 and shown in Figure 4, the utility model with the most basic in first, second brake lining 121, the structural form of 123 configuration one radiating fin 122 is embodiment, the structure of its integral brake disc 1 is for ease of making and keep due structural strength, as shown in Figure 2, its the assembling position 11 be with can with the 121 integrally casting moulding of first brake lining, or as shown in Figure 3, by assembling position 11 and the 123 integrally casting moulding of second brake lining, and as shown in Figure 4, can also be assembling position 11 and radiating fin 122 integrally casting shaped structures forms.
