In the utility model, resin glue materials are avoided being used, the steel back and the ferroalloy friction layer are directly sintered at the high temperature to form the alloy bond layer, therefore, the fastness of the brake plate is increased, the friction layer is not easy to disengage from the steel back owing to high-strength high-frequency use, the ferroalloy brake plate can still work when the temperature is higher than 300 DEG C, hidden safety danger can not be caused for passengers on vehicles, the cost of iron is lower than the cost of copper materials, and the strength of the iron is larger than the strength of the copper materials. The specific gravity of the ferroalloy brake plate is larger; problems, such as fugitive dust and the like, are avoided in the course of brake; and environment is protected. A copper plating layer is wrapped outside the steel back of the ferroalloy brake plate, the ferroalloy brake plate is shaped by compression and is more durable; and the whole ferroalloy brake plate is more suitable for the vehicles used in extreme environment, such as science investigation vehicles, military vehicles and etc., and vehicle driving safety is guaranteed.
Description
Technical field
The utility model belongs to coupling, the clutch of conveying rotary motion, the technical field of break, particularly a kind of automobile-use ferro-alloy braking plate that is applicable to extreme environment.
Background technique
In the brake system of automobile, braking plate is the breaking piece of most critical, has determined the quality of braking effect.
Existing braking plate generally is made of by bonding steel backing and friction plate.Friction plate is made up of friction material, tackiness agent, is compressed in during brake to produce friction on brake disc or the brake drum, thereby reaches the purpose of vehicle deceleration brake.
There is following drawback in existing braking plate:
(1) existing steel backing and friction plate generally all are directly bonding by cohesive materials such as resin glue, yet braking plate is the very high component of utilization rate in the vehicle traveling process, wearing and tearing are very big and heat up very fast, common cohesive materials such as resin glue are just bonding with two opposing sides of steel backing and friction plate, come unstuck easily during near 300 ℃ when the temperature of braking plate, this causes sizable danger in vehicle traveling process;
(2) existing braking plate proportion is lower, use under general environment and can satisfy the demands, but the not good particularly sand and dust of environment can cause environmental problems such as airborne dust more for a long time around, are unfavorable for environmental protection;
(3) existing friction plate adopts Cu alloy material mostly, and the cost of Cuprum alloy is higher, is not suitable for large batch of production.
In sum, existing braking plate is very unscientific for the long-term use of this car type that is used for extreme environment of scientific investigation car and military car particularly for vehicle, might be because of the carbonization of resin glue at high temperature, drop and cause the friction plate of braking plate and steel backing to come off and then accidents caused.
The model utility content
The technical problem that the utility model solves is, because existing braking plate adopts resin glue with friction plate and the bonding structure of steel backing, comparatively simple, and coming unstuck or because of the improper situation that vehicle safe driving is constituted a threat to of material because of the user mode carbonization that can't bear high-intensity use and high temperature may appear in the braking plate that causes, and the phenomenon of befouling environment such as airborne dust appears, especially be not suitable for scientific investigation car and military car etc. and be used for the problem of the car type of extreme environment, and then a kind of ferro-alloy braking plate of optimizing structure is provided.
The technological scheme that the utility model adopted is, a kind of ferro-alloy braking plate, comprise steel backing and ferro-alloy friction layer, described ferro-alloy friction layer is fixed on the steel backing, is provided with between described ferro-alloy friction layer and the steel backing the mating face high temperature sintering of ferro-alloy friction layer and steel backing and the alloy bonding layer that forms.
Preferably, described steel backing skin is coated with copper layer.
Preferably, described ferro-alloy braking plate compression moulding.
The utility model provides a kind of ferro-alloy braking plate of optimizing structure, be set to the ferro-alloy friction material by friction layer, and directly ferro-alloy friction layer and steel backing high temperature sintering are formed the alloy bonding layer, avoided employing resin glue material, increased the soundness of brake block, be difficult for friction layer and steel backing being broken away from because of the high-frequency use of high strength, still can proper functioning greater than 300 ℃ the time, can not cause potential safety hazard to the passenger on the vehicle, and the cost of iron is low than copper product, and intensity is big than copper product; The utility model proportion is bigger, has avoided problems such as airborne dust in brake process, the protection environment; Steel backing of the present utility model is coated with copper layer, and the compression moulding of ferro-alloy braking plate has guaranteed that the utility model is more durable, and integral body is more suitable for the car type that scientific investigation car and military car etc. are used for extreme environment, has guaranteed the Security of vehicle driving.

Embodiment
Below in conjunction with embodiment the utility model is described in further detail, but protection domain of the present utility model is not limited to this.
Shown in Fig. 1～5, the utility model relates to a kind of ferro-alloy braking plate, comprise steel backing 1 and ferro-alloy friction layer 2, described ferro-alloy friction layer 2 is fixed on the steel backing 1, is provided with the alloy bonding layer 3 that ferro-alloy friction layer 2 is formed with the mating face high temperature sintering of steel backing 1 between described ferro-alloy friction layer 2 and the steel backing 1.
Described steel backing 1 skin is coated with copper layer 4.
The compression moulding of described ferro-alloy braking plate.
The utility model by adopt ferro-alloy friction layer 2 establish with steel backing 1 on, and directly ferro-alloy friction layer 2 and steel backing 1 high temperature sintering are formed alloy bonding layer 3, avoided employing resin glue material, increased the soundness of brake block, friction layer 2 and steel backing 1 are broken away from, still can proper functioning greater than 300 ℃ the time, can not cause potential safety hazard to the passenger on the vehicle.
It is ferro-alloy friction layer 2 that the utility model is provided with friction layer, and fusing point is higher, and hardness is bigger, more durable, and cost is low than copper product, so safety coefficient is higher, and helps large batch of production.
The utility model proportion is bigger, so avoided problem such as airborne dust in brake process, the protection environment is particularly suitable for using in rugged environment.
Because braking plate uses on vehicle frequently, so wearing and tearing are bigger, if untimely replacing braking plate, steel backing 1 will directly contact with brake disc, finally can lose braking effect and damage brake disc, this has increased the replacement cost of braking plate, frequency rising, the especially car type that need in extreme environment, work for professional scientific investigation car and military car etc. of vehicle maintenance, the wearing and tearing of braking plate are originally just big especially, can't accomplish frequent replacing again, this is the expansion that is unfavorable for very much scientific investigation work and military work; The utility model is through the adjustment to the braking plate structure, increased the soundness of braking plate, make and form alloy bonding layer 3 by high-temperature calcination between steel backing 1 and the ferro-alloy friction layer 2, be difficult for because the high-frequency use of braking plate high strength causes coming unstuck and the passenger on the vehicle is caused potential safety hazard, and hardness is bigger, more durable, be more suitable for being used for the vehicle of extreme environment, guaranteed the Security of vehicle driving.
