Abstract

The utility model discloses a disc brake pad. The disc brake pad comprises a backing plate, a friction material pad, a gasket, a casing pipe hole, a casing pipe hole II, a friction material, a convex part and a convex part II and is characterized by comprising the backing plate and the friction material pad, wherein the backing plate is provided with the casing pipe hole and a branch casing pipe II, and the gasket is adhered to the backing plate through an adhesive; the friction material is used for filling the casing pipe hole, but the casing pipe hole is not fully filled with the friction material, and the gasket can deform and enter a hollow part of the casing pipe hole so as to form the convex part; and the periphery of the gasket can deform and enter a hollow part of the casing pipe hole II so as to form the convex part II. The disc brake pad has the beneficial effects that the adhesion of the gasket on the backing plate is improved, an enough resistance is supplied so as to cut the gasket from the backing plate during heavy type braking, and the disc brake pad is convenient, practical and difficult o slide and damage.

Description

Disc type brake pad

Technical field

The utility model relates to a kind of automobile component, particularly a kind of disc type brake pad.

Background technique

At the disk type braker of Hyundai Motor and commerial vehicle, install and more and more use attenuating noise and/or thermal boundary pad as a part for compound disc brake pad and gasket assembly.Pad used can be metallizing or fiber reinforced plastic saw lumber, often by Bond, sticks to the back side of brake pad, and Bond is as contact adhesive or thermosetting adhesive.The Bond of two types may lose efficacy under heavy duty is used, and because disc type brake pad can reach high temperature, pad is easy to slide with respect to disc type brake pad, can drop out from clamp sometimes, or cause damage.

Model utility content

The purpose of this utility model has been to provide a kind of disc type brake pad through improvement, in order to solve above-mentioned existing issue.

The technical solution of the utility model is as follows: a kind of disc type brake pad, include backboard, friction material pad, pad, collar aperture, and collar aperture two, friction material, protuberance, protuberance, is characterized in that: disc type brake pad includes backboard, friction material pad; On backboard, have collar aperture and minute sleeve pipe two, pad is adhered on backboard by adhesive.Friction material is filled to some extent to collar aperture, but that collar aperture is not filled by it is full, and the empty portion that pad can deformation enters collar aperture forms a protuberance.In collar aperture two, the periphery of pad can deformation enter a protuberance two of empty portion's formation of collar aperture two.

The beneficial effects of the utility model are: increase pad and are bonded at the stickiness on backboard and provide enough resistances that pad is sheared off from backboard when heavy type is braked, and convenient practical again, be not easy to slide and damage.

Fig. 2 is that Fig. 1 pads example from the figure of opposite angle; Fig. 3 along Fig. 2 line B-B sectional view;

Fig. 4 is the end elevation of pad and disc type brake pad assembly.

In figure, indicate: 1, backboard, 2, friction material pad, 3, pad, 4, collar aperture, 4 ', collar aperture two, 5, friction material, 6, protuberance, 7, protuberance two.

Embodiment

By reference to the accompanying drawings, the utility model is described in further detail.

As shown in the figure, the utility model disc type brake pad, includes backboard 1, friction material pad 2, pad 3, collar aperture 4, collar aperture 24 ', friction material 5, protuberance 6, protuberance 7, it is characterized in that: disc type brake pad includes backboard 1, friction material pad 2; On backboard 1, have collar aperture 4 and minute sleeve pipe 24 ', pad 3 is adhered on backboard 1 by adhesive.5 pairs of collar aperture 4 of friction material are filled to some extent, but that collar aperture 4 is not filled by it is full, and the empty portion that pad 3 can deformation enters collar aperture forms a protuberance 6.Collar aperture 24 ' in, the periphery of pad 4 can deformation enter a protuberance 27 of empty portion's formation of collar aperture two.

As shown in the figure, overall structure of the present utility model as described above.Wherein the dotted line of the position distribution of collar aperture 4 in Fig. 2 is visible.From the opposite side of friction material pad 2 backboards 1, a pad 3 is by suitable adhesive, as thermosetting property adhesive sticks on backboard.Relatively thick pad 3, can be for there being rubber coating steel plate, and backboard 1 is thicker steel, and Fig. 4 has well set forth friction material pad 2.In typical mat, the thickness of friction material pad is 12mm, and backboard 1 is 5mm, and pad 0.80mm pads as spring steel saw lumber, and being covered with nitrite rubber is basic composition, and the thickness of spring steel is 0.35mm.

As shown in Figure 3, collar aperture 4 is not filled full by friction material 5, makes pad 3 deformation to enter a protuberance 6 of empty portion's formation of collar aperture, stops the slip of the pad on backboard.In collar aperture 4 ', pad 3 does not have complete covering jacket pore, but that periphery that is pad can deformation enter a protuberance 27 of empty portion's formation of collar aperture.It is to be understood that, in the figure describing in example, due to collar aperture hollow, each is not exclusively to fill up, and pad deformation enters in the space staying, and guarantees to stop to slide.

It should be noted that preferred gasket material is for after enough deformation is out of shape flat gasket, protuberance enters as filling up collar aperture.In this case, the material of pad can manufacture plain film, thereby people can be cut.Use this material also can on pad, form protuberance by gasket material filling is entered to deformation in the collar aperture of not filling up, pad is still in the original position of backboard.Particularly preferred gasket material comprises sheet material or netted metal, and as plating or the steel of plating not, therefore, sheet metal is coated with rubber or fiber strengthens there is the composite material of pressing layer or grid sheet metal, and it is very suitable gasket material.Pad comprises a sheet metal or grid, and the thickness of metal is conventionally in scope 0.15mm-0.50mm.When this pad is installed on backboard, by suitable shaping jig pressure pad sheet, enter a positive mechanical location of collar aperture formation relative with Slideslip.It should be noted that if there are a plurality of collar aperture on backboard, need to more than the protuberance of two pads, not enter in collar aperture, also can fill some collar aperture completely with friction material if necessary.
