Abstract
The utility model discloses a stratified brake disc used for braking of motor vehicles. The stratified brake disc is of a stratified structure, and an abrasion-resisting material layer is installed on the working surface of the brake disc body. The preferable scheme includes that the brake disc body is made of aluminum base composite materials. The thickness of the abrasion-resisting material layer is 6-7mm to meet actual needs. According to the stratified brake disc, the abrasion-resisting material layer with the certain thickness is installed on the working surface of the brake disc body, wherein the friction and abrasion performance of the abrasion-resisting material layer is better than that of the brake disc body, so that service life of the stratified brake disc is prolonged, and maintenance and repair cost of the motor vehicles is lowered.
Description
Technical field
The utility model relates to the braking device of a kind of braking device of Motor Vehicle, particularly a kind of rolling stock.
Background technique
In recent years, along with rolling stock to light weight, at a high speed, safe, multi-functional, long lifetime future development, vehicle is had higher requirement with the performance of key components and parts material.For the loss of weight of realizing rolling stock and prolong working life of brake disc, need develop the new product that can substitute the brake disc that generally uses the brake disc made by ferrous materials at present and made by pure aluminum alloy.
At present the employed disc material of rolling stock has two kinds in iron quality metal material and composite material.Iron quality metal material mainly comprises cast iron system, cast steel and forged steel etc., and ferrous material has that density is large, poor thermal conductivity, be prone to the shortcoming such as hot crack, is difficult to satisfy the requirement of vehicle lightweight and speed up.Composite material comprises carbon/carbon compound material and aluminum matrix composite, the advantage such as carbon/carbon compound material has lightweight, heat-resistingly to be split, friction and wear behavior excellence, but its complicated process of preparation is with high costs.Aluminum matrix composite has the advantages such as density is little, thermal conductivity good, friction and wear behavior is good, and cost is moderate, is abroad developing and is just using in entrucking.Germany has taken the lead in developing the aluminum matrix composite brake disc of alternative magnesium iron brake disc, and the weight of each brake disc alleviates to 65kg from 115kg.Japan has then developed the aluminum matrix composite brake lining, and service testing.But the brake disc of aluminum matrix composite is shorter working life, and maintenance and the cost of overhaul of rolling stock's braking system are higher.
Summary of the invention
Technical problem to be solved in the utility model is for the prior art deficiency, to provide a kind of working life long brake disc.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of layering brake disc, it is characterized in that the layering brake disc has hierarchy, and be provided with wear-resistant material layer at the working surface of brake disc disk body.
As preferred version, described layering brake disc disk body is to be made by aluminum matrix composite.
For satisfying actual demand, the thickness of described wear-resistant material layer is the 6-7 millimeter.
Compared with prior art, the beneficial effect that the utility model has is: the disclosed layering brake disc of the utility model arranges certain thickness wearing layer at brake disc disk body working surface, the friction and wear behavior that its friction and wear behavior is made material than brake disc disk body is good, therefore, the operating life of brake disc is prolonged, thereby reduce maintenance and the cost of overhaul of rolling stock.
Description of drawings
Fig. 1 is the utility model one embodiment's plan view;
Fig. 2 is the longitudinal section view of A-A face among the embodiment.
Among the figure, 1 is depicted as wear-resistant material layer, and 2 are depicted as the brake disc disk body of aluminum matrix composite.
Embodiment
Be an embodiment of the present utility model such as Fig. 1, mode by jet deposition is adhered to certain thickness wear-resistant material layer at aluminum-base composite material brake disc disk body working surface, shown in the material layer 1 of 2 li in accompanying drawing, make brake disc have good wear Characteristics.Consider the reality needs, the thickness of wear-resistant material layer is set to the 6-7 millimeter.Aluminum-base composite material matrix makes brake disc have good and the enough intensity of thermal diffusivity, and when guaranteeing brake disc work, the dissipation of heat that in time produces by braking the time also makes the failure modes such as brake disc does not crack, distortion.Brake disc is realized the braking of vehicle by wearing layer, and wearing layer has the wear Characteristics that is better than aluminum-base composite material matrix, to prolong the working life of brake disc, reaches the maintenance and the cost of overhaul that reduce rolling stock.
