Abstract
The utility model discloses a combined double-layered brake pad, which comprises a steel plate and a frictional layer. The frictional layer is located and attached on the upper surface of the steel plate. The frictional layer consists of a first frictional layer and a second frictional layer. The second frictional layer is located on the neighboring side of the first frictional layer and is attached on the first frictional layer. The combined double-layered brake pad has a good wear-resistant effect, and the frictional stability of the combined double-layered brake pad and a brake disc is good.
Description
Technical field
The utility model relates to a kind of braking plate, relates in particular to the brake block that a kind of automobile is used.
Background technique
In the brake system of automobile, brake block is the breaking piece of most critical, and the quality of all braking effects all is that brake block plays a decisive role, so the brake block of agreeing is the patron saint of people and automobile.At present; Automobile is mainly fitted each other through the high temperature compacting by steel plate and friction material with brake block and is constituted; In the braking automobile process, the friction material layer of brake block and brake disc mutual friction mutually produce the power that makes automobile brake; So whether the friction stationarity between brake block and the brake disc is good, directly determines the quality of braking effect.And in long-term using process; Because the different parts of friction material effect and brake disc; Therefore the different parts degree of wear is also inconsistent; Make the friction stationarity variation between brake block and the brake disc, influence braking effect and cause safety problem, in use also can produce irregular vibrations and bigger noise.
The model utility content
The technical problem that the utility model will solve provides a kind of brake block, makes to have good friction stationarity between brake block and the brake disc.
For solving the problems of the technologies described above, the technological scheme of the utility model is: comprise steel plate and friction layer; Friction layer is positioned at the upper surface of steel plate, and fits with steel plate; It is characterized in that: said friction layer comprises first friction layer and second friction layer; Second friction layer is positioned at the adjacent side of first friction layer, and fits with first friction layer.Friction layer adopts the composite double layer structure, can improve the friction stationarity between brake block and the brake disc effectively.
A kind of preferred as the utility model, said first friction layer is the fiber composite layer.
A kind of preferred as the utility model, said second friction layer is ceramic friction layer.The friction layer that adopts above-mentioned material to process is environment friendly and pollution-free, wear-resisting effective.
In sum, the composite double layer brake block of the utility model has good wear-resisting effect, and has good friction stationarity between the brake disc.
Description of drawings
Fig. 1 is the structural representation of the utility model composite double layer brake block.
Wherein, 1, steel plate; 21, first friction layer; 22, second friction layer.
Embodiment
As shown in Figure 1, the composite double layer brake block of the utility model comprises steel plate 1 and friction layer; Steel plate 1 is fitted with friction layer; Said friction layer comprises first friction layer 21 and second friction layer, 22, the first friction layers 21 and 22 applyings of second friction layer.Wherein first friction layer 21 is fiber composite layers, is formed by Steel Fibre, glass fibre, the braiding of heatproof organic fiber material; Second friction layer 22 is ceramic friction layers of being processed by the ceramic mould friction material.
First friction layer 21 and second friction layer 22 with the contact process of brake disc (not drawing among the figure) in, be converted into heat energy to the kinetic energy of automobile by friction, thereby reach the purpose of braking.First friction layer 21 with second friction layer 22 because the material that adopts is different so rub proofness is inconsistent; But also because its position is different; So after long-term work; The degree of wear of first friction layer 21 and second friction layer 22 is consistent, has guaranteed the clearance seal property between brake block and the brake disc, thereby has guaranteed the friction stationarity.
To one skilled in the art, can make other various corresponding changes and deformation, and these all changes and deformation should belong within the protection domain of the utility model claim all according to the technological scheme and the design of above description.
