Abstract
Description
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
In other words, the inboard 1 constituting the conventional damping disk is formed with an empty space for inserting the
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,
A brake damping disk, comprising: an inboard forming one or more inboard holes; An outer board coupled to one surface of the inboard and forming at least one outer board hole corresponding to the position and number of the inboard holes; An insert plate inserted between the inboard and the outer inboard and forming at least one insert plate hole corresponding to the position and number of the inboard holes; And at least one bolt coupled to each of the inboard hole, the outer inboard hole, and the insert plate hole to fasten the inboard, the outer inboard and the insert plate to each other.
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.
