Preferably, described major ingredient layer is provided with the groove for chip removal and heat radiation in braking process away from the one side of described bed course.

Preferably, the degree of depth of described groove and the consistency of thickness of described major ingredient layer.

Preferably, the V-shaped structure of described groove cross section.

Preferably, described groove comprises the first groove and the 2nd groove, and described first groove and described 2nd groove intersection are arranged.

Further preferably, the length direction of described first groove is consistent with the length direction of described major ingredient layer, and the length direction of described 2nd groove is consistent with the width of described major ingredient layer.

Preferably, the quantity of described first groove is for being not more than 2, and the quantity of described 2nd groove is not more than 3 articles.

Preferably, described major ingredient layer and described bed course are by being adhesively fixed.

Preferably, the main body of described coattail board forms dovetail-indent, and the dovetail that described bed course is provided with described dovetail-indent mates, described dovetail is embedded in described dovetail-indent.

Preferably, described coattail board is sheet metal component.

As mentioned above, it is necessary, brake pad of the present utility model, there is following useful effect:

Brake pad described in the utility model comprises major ingredient layer, bed course and coattail board; Described major ingredient layer is connected by described bed course with described coattail board, the generation of the phenomenon such as can effectively avoid brake lining to fall block in braking process, to break, the breaking system being applicable to the transportation equipments such as train, while guaranteeing driving safety, it is possible to reduce working cost and cycle cost.

Embodiment

By particular specific embodiment, enforcement mode of the present utility model being described below, person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages of the present utility model and effect easily.

Refer to Fig. 1 to Fig. 2. Notice, structure that this specification sheets institute accompanying drawings illustrates, ratio, size etc., all only content in order to coordinate specification sheets to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore do not have an essential meaning in technology, the adjustment of the modification of any structure, the change of proportionlity or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain. Simultaneously, this specification sheets is quoted as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and it is not used to limit the enforceable scope of the utility model, the change of its relative relation or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.

Referring to Fig. 1 and Fig. 2, the utility model provides a kind of brake pad, comprises, major ingredient layer 1, bed course 2 and coattail board 3; Described major ingredient layer 1 is connected by described bed course 2 with described coattail board 3.

Fig. 1 is shown as the schematic side view of brake pad described in the utility model one embodiment. Described major ingredient layer 1 is provided with one article of first groove 4 and two article of the 2nd groove 5 away from the one side of described bed course 2, the length direction of described first groove 4 and the length direction of described major ingredient layer 1 are basically identical, and the length direction of described 2nd groove 5 and the width of described major ingredient layer 1 are basically identical. The cross section of the first groove 4 and the 2nd groove 5 is V shape, and the thickness of its degree of depth and described major ingredient layer 1 is basically identical, it is possible to the limit that may wear to as brake pad indicates. First groove 4 and the 2nd groove 5 can make air circulation, improve profiling temperatures, it is possible to ensure the chip removal in braking process and heat radiation.

Fig. 2 is shown as the schematic cross-section of brake pad described in the utility model one embodiment. Described major ingredient layer 1 by being adhesively fixed, after bonding, has good bonding force and shearing resistance therebetween with described bed course 2. The main body of described coattail board 3 forms dovetail-indent, and described bed course 2 is provided with the dovetail 21 mated with described dovetail-indent, and described dovetail 21 is embedded in described dovetail-indent, thus connects described major ingredient layer 1 and described coattail board 3. Coattail board 3 is thin plate sheet metal component, uses when installing with caliper.

Brake pad of the present utility model is applicable to the breaking system of the transportation equipments such as train, so that as train braking brake lining, coattail board 3 is connected with caliper, after receiving brake command, caliper promotes coattail board 3 and bed course 2, by major ingredient layer 1 and retarding disc clamping, plays the effect of braking.
