Abstract
The utility model relates to a frictional piece fixing device for a plate-type braking piece. The frictional piece fixing device comprises a bottom plate and a frictional piece. The frictional piece is fixed on the bottom plate. A steel nail is arranged between the frictional piece and the bottom plate. A nail cap of the steel nail is fixed in the frictional piece and a nail head is fixed in the bottom plate. The frictional piece fixing device is reasonable in structural design, and guarantees service life of the braking piece due to the fact that the frictional piece and the bottom plate are fixed through the steel nail and delaminating phenomenon does not appear.
Description
Technical field
The utility model relates to a kind of friction plate fixing device of disc brake pad, belongs to the auto-parts technical field.
Background technique
Brake block is mainly used in the brake of the communications and transportation such as automobile, motorcycle, and brake block must carry out to the formula material of friction plate high temperature hot pressing in manufacture process, synthetic being fixed on the base plate.Brake block is mechanically stressed by on the base plate in use, brake block be fixed on brake disc on the wheel and rub and form brake.Friction plate and base plate have very large shearing force, if friction plate and base plate do not pass a test in the high temperature hot pressing synthetic technology, automobile is in brake process, and brake block is under the friction roll extrusion of brake disc, and friction plate and base plate delamination can cause serious traffic accident.So friction plate and base plate high temperature hot pressing synthetic technology are the key technologies of making brake block.Generally be hair plates on the synthetic face of prior art base plate, also have steel wire and base plate to be welded and fixed, certain using effect is arranged, but effect is little, the time is with easily causing for a long time friction plate and base plate delamination, steel wire and base plate sealing-off, and working life is short.
The model utility content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, and can effectively friction plate and base plate be fixed, and is difficult for the friction plate fixing device of delamination.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of friction plate fixing device of disc brake pad, comprise base plate, and it is characterized in that: it also comprises friction plate, friction plate is fixed on the base plate; Be provided with steel nail between friction plate and the base plate, the head of a nail of steel nail is fixed in the friction plate, and ailhead is fixed in the base plate.
Fix by high temperature hot pressing between friction plate described in the utility model and the base plate, firmly difficult drop-off.
Fix by high temperature hot pressing between the head of a nail of steel nail described in the utility model and the friction plate, between the ailhead of steel nail and the base plate by being welded and fixed.
The utility model compared with prior art has following positive effect: reasonable in design, and steel nail is fixed friction plate and base plate, can delamination, guarantee the working life of brake block.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that Fig. 1 removes friction plate.
Fig. 3 is that steel nail is fixed on sectional structure schematic diagram on the base plate in the utility model.
Fig. 4 closes the structural representation of friction plate among Fig. 3.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1～Fig. 4, the present embodiment comprises base plate 1 and friction plate 2, and friction plate 2 is fixed on the base plate 1; Be provided with steel nail 3 between friction plate 2 and the base plate 1, the head of a nail 4 of steel nail 3 is fixed in the friction plate 2, and ailhead 5 is fixed in the base plate 1.
In the present embodiment, fix by high temperature hot pressing between friction plate 2 and the base plate 1, firmly difficult drop-off.
In the present embodiment, fix by high temperature hot pressing between the head of a nail 4 of steel nail 3 and the friction plate 2, between the ailhead 5 of steel nail 3 and the base plate 1 by being welded and fixed.
During use, as shown in Figure 3, first steel nail 3 is hammered into base plate 1 and be welded and fixed, the head of a nail 4 of steel nail 3 exposes; As shown in Figure 4, then cover on the base plate 1 by the raw material of grinding tool with friction plate 2, the head of a nail 4 of steel nail 3 is positioned at the raw material of friction plate 2; Again the raw material of friction plate 2 carried out high temperature hot pressing, make friction plate 2 and base plate 1 integrator, and the head of a nail 4 is fixed in the friction plate 2.The utility model make brake block with the friction and rolling of brake disc under, friction plate 2 and base plate 1 can delaminations, and long service life, guarantee the braking effect of brake block, generation avoids traffic accident.
In addition, need to prove, the specific embodiment described in this specification, as long as the undeclared concrete shape of its part and size, then this part can be any shape and size that adapt with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done according to the utility model patent, be included in the protection domain of the utility model patent.
Claims (3)
