Description

Brake pad for vehicle

The present invention relates to a vehicle brake pad that can increase the firmness of the brake pad to maximize the accuracy and safety of the braking action.

In general, a brake pad for a vehicle has a structure in which a friction member is molded to a predetermined thickness toward a brake disc on a front surface of a pad plate. In general, the brake pad is braked while the front friction surface of the friction member contacts the brake disc.

Here, briefly looking at the assembly method of the brake pad was manufactured by a simple method of applying an adhesive to the front of the pad plate, and then pressing and attaching the back of the friction member thereon, significantly lowering its robustness and safety problems Pointed out.

That is, when the brake pads are in contact with the brake disk rotating at high speed, high thermal contact friction heat is generated by the mutual frictional force, and the high thermal contact frictional heat affects the adhesive fixing the friction member, thereby inhibiting the adhesive force. If it occurs for a long time, the friction member is separated or pushed.

In addition, during rapid contact with the brake disc due to rapid braking, the rotational force due to the high-speed rotation of the brake disc is concentrated and transmitted to the friction member, thereby causing a great ruin of safety that causes the friction member to completely break or break from the brake pad, causing a brake rupture phenomenon. It was a real situation.

As described above, the brake pad, which has conventionally configured one side surface of the pad plate and one side surface of the friction member, has excellent rigidity against the force applied in a straight line by simply surface bonding, but at high speed frictional force of the brake disc, The member has a closed end which is easily twisted or pushed away from a pad plate,

There is a need to correct this soon.

The present invention has been invented to improve the conventional problems, and in particular, an object of the present invention is to provide a brake pad for a vehicle which can maximize the accuracy and safety of braking with its excellent strength by increasing the bonding force between the pad plate and the friction member. .

The brake pad for a vehicle of the present invention, which is presented as a solution to the above problem, applies an adhesive 2 to the front surface of the pad plate 1 and then presses and adheres the back surface of the friction member 3,

The front surface of the pad plate is formed with a plurality of engaging grooves or engaging projections, characterized in that the back surface of the friction member is coupled to the concavities and convexities.

On the other hand, the irregularities are formed crosswise in the form of '+', or crosswise in the form of 'X'.

The present invention increases the bonding force between the pad plate and the friction member in the above-described configuration, thereby enhancing the braking accuracy and safety of the brake disc. In particular, the friction member is pushed away from the pad plate, or is separated or damaged even in the strong rotational force (when braking) of the brake disc. There is an effect that can be prevented such as problems (brake rupture phenomenon).

1 is a partial side cross-sectional view of the present invention,
2 is a brake pad assembly example,
3, 4, 5, 6 is another exemplary view of the irregularities proposed in the present invention.

An embodiment of the present invention will be described with reference to the accompanying drawings.

Further, the detailed description of known functions and configurations that may unnecessarily obscure the gist of the present invention will be omitted.

As shown in FIG. 1, a vehicle brake pad (a) is usually formed by applying an adhesive (2) to the front of the pad plate (1) and then bonding the back surface of the friction member (3) to the pad plate (1). (1) To form a concave-convex (4) formed by a plurality of engaging grooves 11 or engaging projection (11 ') to the front so that the friction member 3 is pressed and bonded thereto.

Here, the unevenness 4 has a cross section of "

Figure pat00001
It can be variously formed in the form of "," ∨ ",", ∪ ".

When the friction member 3 is attached to the front surface of the pad plate 1, the pressure member is press-coupled through a pressure device so that the rear surface of the friction member 3 corresponds to the unevenness 4 formed on the front surface of the pad plate 1. It is immersed in the shape to be mutually engaged.

This is to maximize the firmness of the brake pad (a) by the double bond configuration of the adhesive (2) and uneven (4).

As described above, the brake pad (a) of the present invention more firmly reinforces the coupling portion between the friction member (3) and the pad plate (1) to which the rotational friction force transmitted from the brake disc is most transmitted during the braking action. It is characteristic.

That is, the present invention constitutes a double combination of the engaging force by the adhesive agent 2 and the friction member 3 into the unevenness 4 by locking and fixing the clamping force. Brake hydraulic pressure is formed at the time of delivery to the caliper housing (not shown). Then, the brake member presses the friction member of the caliper housing, which is installed symmetrically by the braking hydraulic pressure, with the brake disk. At this time, the friction member between the brake disk having a strong rotational force and the pad plate operated by the braking hydraulic pressure is applied. Since the rotational frictional resistance with the low brake disk is greatly generated, the frictional resistance is firmly coped with the double coupling between the coupling member and the pad plate, so that more rapid, accurate and safe braking is achieved.

For reference, in the past, the friction member is adhesively bonded to the surface by the pad plate depending on the adhesive. When the driver suddenly brakes, the friction member does not firmly cope with the strong frictional resistance generated in the brake disc, or is pushed away from the pad plate. Some of the brake rupture shapes, such as breakout or breakage, occurred, causing a great problem of safety.

On the other hand, the present invention is configured by forming the grooves (11) or the locking projection (11 ') at regular intervals to the concave-convex (4) formed in the pad plate (1).

In addition, when the friction member 3 is pressure-coupled to the pad plate 1 by cross-sectioning the unevenness 4 in the form of '+' newly or cross-forming in the form of 'X', the recessed portion is increased. In addition to having superiority, the reliability of the braking action can be further enhanced.

For reference, the convex and convex may be formed by the pad plate, and the convex and concave convex may be formed by the friction member. There is no need to configure separately because it is obvious that the phenomena of the intercalation occurs, and it may cause a problem of unnecessarily increasing the process.

As described above, the present invention is not limited to the above-described embodiments, and may be modified and implemented by those skilled in the art without departing from the scope of the claims of the present invention. Modifications are within the scope of the present invention.
