Description

Brake Damping Disk with a Bolt Jointing Type

The present invention relates to a brake damping disk for reducing brake squeal noise. More specifically, the inboard constituting the brake disk is formed of two parts, an inboard and an outer inboard attached to one surface of the inboard, An insert plate is inserted between the inboard and the outer inboard, and the inboard and the outer inboard are fastened to each other by using a plurality of bolts, so that the bolt clamping type brake can reduce squeal noise by the insert plate. Relates to a damping disc.

In general, a brake device mounted on an automobile is for reducing a vehicle speed of a driving vehicle or shifting to a completely stopped state. In general, an oil compressed from a master cylinder or a high pressure compression stored in an air tank is applied according to the pressure of a brake pedal. It is a means for pressurizing air to the brake mechanism provided on the wheel side and braking the brake drum or the disc wheel through the medium.

A device including a brake disc of the conventional brake device is configured to obtain a braking force by rubbing the pad to the brake disc during braking. In this case, a so-called squeal noise is generated. This squeal noise is caused by the energy generated by the friction of the pads on the disk wheel, which is caused by resonance in the brake system, and the generated noise is high frequency noise in the range of about 1 to 16 KHz. Therefore, the squil noise generated in the brake during braking has a problem that can cause a significant discomfort to the vehicle occupant.

In order to prevent this, the conventional brake disc device has a structure that attenuates squeal noise by inserting a separate plate into the inboard in the damping disc.

Figure 1 shows a conventional damping disk structure made as described above.

The conventional damping disk structure shown has a structure in which a separate plate 2 is inserted into the inboard 1 in the damping disk as described above.

In other words, the inboard 1 constituting the conventional damping disk is formed with an empty space for inserting the plate 2 in the form of a thin plate, the plate-like plate 2 is inserted into the empty space to squeal noise It is made of a structure that attenuates. However, in the present casting process, the above-described structure has considerable difficulty in inserting the plate 2 between the disk inboards 1. In particular, in order to insert the plate 2 having a thin plate shape as described above between the empty spaces formed in the disk inboard 1, another device for the insertion of the plate 2 is required, in which case the process There was a disadvantage to be complicated. In addition, in the case of inserting a casting for manufacturing a conventional damping disk, the casting is quenched at the contact surface with the plate 2, the poor structure and poor adhesion occurs to have a disadvantage that adversely affects the quality. In addition, the prior art of the above-described method has a problem that the damping insert plate (2) is melted during the injection of the casting when manufactured in the existing casting method, therefore, the conventional damping disk structure as described above until the injection of the molten metal There was a disadvantage in that the proper temperature of the plate 2 should be maintained continuously.

The conventional damping disk as described above has a great difficulty in applying to mass production due to the above problems.

The present invention has been made to solve the above problems,

The inboard constituting the brake damping disk is composed of two parts, an inboard and an outer inboard, and an insert plate is inserted between the inboard and the outer inboard, and the inboard and the outer inboard are plural. It is an object of the present invention to provide a brake damping disk of the bolt fastening method to reduce the squeal noise generated from the brake damping disk by easily inserting the insert plate on the inboard by using the bolt of the.

The present invention for achieving the above object,

In addition, the outer board hole, characterized in that made of a two-stage structure respectively corresponding to the head and the body of the bolt so that the head of the bolt is completely inserted into the outer board.

In addition, the inboard hole is characterized in that the screw thread corresponding to the screw thread formed in the bolt is formed on the inner surface.

The present invention having the configuration as described above,

By forming the inboard in two parts, the process of inserting the insert plate into the inboard can be simplified and facilitated, and the quality of the inboard into which the insert plate is inserted can be improved compared to the prior art, so it is easy to mass-produce. There is an effect that can be applied.

By fastening the inboard divided into two parts of the inboard and the outer inboard using a plurality of bolts, the inboard divided into two parts can be firmly coupled to each other. Therefore, there is an effect that can firmly secure the insert plate inserted between the inboard and the outer inboard.

The insert plate inserted into the inboard serves as a kind of friction plate in the inboard, thereby canceling the excitation force causing fine vibration of the disk, thereby reducing the noise generated from the brake damping disk.

Figure 6 shows the noise improvement principle of the bolted brake damping disk according to an embodiment of the present invention.

As shown, the brake damping disk of the bolt fastening method of the present invention is hydraulic pressure for braking in the direction A of Figure 6a when braking. At this time, a micro displacement occurs in the B direction of FIGS. 6A to 6C, that is, in the radial direction of the brake damping disk due to the action of the hydraulic pressure, and the micro displacement further causes squeal noise.

At this time, since the insert plate 30 is inserted between the inboard 10 and the outer board 20, the insert plate 30 serves as a kind of friction plate, and fine vibration of the brake damping disk is performed. The effect of reducing noise is generated by canceling the excitation force.

7 is a table showing the results of the evaluation of the low temperature squeal noise of the conventional brake damping disk and the bolt clamping brake damping disk of the present invention, Figure 8 is a view of the conventional brake damping disk and the bolt clamping brake damping disk of the present invention It is a graph showing the result of squeal noise evaluation.

Referring to the drawings, it can be seen that the noise frequency frequency and the number of noise generation of the brake damping disk of the present invention is significantly reduced compared to the conventional brake damping disk, and the magnitude of noise is significantly reduced regardless of the size of the friction material. Can be.

As described above, the bolt damping brake damping disk of the present invention can significantly reduce the squeal noise of the brake damping disk, and facilitate the insertion of the insert plate 30, thereby producing a damping disk.

As mentioned above, although the preferred embodiment of the bolt-brake type brake damping disk of the present invention has been described in detail, this is merely presented as a specific example to aid in understanding the present invention, and is not intended to limit the scope of the present invention. . It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
