Japanese Patent No. 3749716 International Publication No. 2004/071856 Pamphlet

  The brake product and each part can be discriminated by attaching an ID to each of the brake product and a plurality of parts constituting the brake product by stamping paint or the like, and visually judging the ID. However, for example, in order to discriminate each part, there are many cases where visual inspection is not possible unless the brake product is disassembled, and a great amount of labor and cost are required.

  On the other hand, in recent years, product management using IC tags has been performed in various fields. By attaching an IC tag to a target product, information can be read and written. Therefore, if an IC tag can be attached to the brake product, it is possible to record detailed product information and information such as maintenance history on the IC tag, and information management of the brake product can be easily performed. However, when IC tags are applied to brake products, the performance of IC tags can be fully demonstrated unless sufficient consideration is given to the heat at the time of braking, the influence of moisture such as rainwater, and the environmental resistance of dust. I can't let you. In addition, the brake product is composed of a plurality of parts, but in order to efficiently manage the information of the brake product using the IC tag, the brake product composed of the information possessed by each part and the plurality of parts has. It is preferable to efficiently associate and manage information.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a technology related to a brake product including an IC tag that has excellent environmental resistance and can easily manage information as compared with the related art. .

In the present invention, the following means are adopted to solve the above-described problems. That is, the present invention is a method for managing a brake product composed of a plurality of parts, and an IC tag capable of recording and reading information in consideration of the environmental resistance of the mounting position is provided on the brake product. At least one of identification information for identifying a part configuration of the brake product, quality information regarding the initial quality of the brake product, and maintenance information regarding the maintenance history of the brake product. And a step of recording the attribute information recorded on the IC tag in a non-contact manner, and performing information management of each part based on the read attribute information. .

  According to the present invention, by attaching an IC tag capable of recording and reading information at a position where environmental resistance is considered, the performance of the IC tag can be sufficiently exhibited. Further, by recording attribute information on the IC tag and appropriately reading or updating the recorded attribute information, it is possible to improve information management and traceability of brake products. The information management is, for example, calculation of replacement time or calculation of maintenance inspection time of the brake product. The quality information included in the attribute information can be exemplified by the dimensional accuracy of the brake product.

  In order for the IC tag attached to the brake product to exhibit its performance sufficiently, it is necessary to sufficiently consider the environmental resistance at the position where the brake product is attached. The environmental resistance can be exemplified by the degree of temperature rise when the brake is operated at the position where the IC tag is attached, and the degree of influence of damage to the IC tag due to stepping stones when traveling in a brake product mounted on a vehicle. . The temperature rise at the time of brake operation considers frictional heat at the time of brake operation, and the position where the IC tag is attached is preferably a position where the temperature rise at the time of brake operation is small. In addition, in a brake product mounted on a vehicle, it is necessary to consider the influence of stepping stones during traveling, and it is preferable to attach an IC tag to a place where the amount of stepping stones is small or where it is difficult to hit.

  The environment in which the brake product is placed varies, and the environmental resistance can be exemplified by the degree of influence of water such as rain water and the degree of influence of dust. The position where the IC tag is attached is preferably a position that is less affected by water and less affected by dust.

  Brake products are used in vehicles such as automobiles and motorcycles, industrial machines, and the like. Examples of the brake product used in the vehicle include a drum brake and a disc brake. The method for managing a brake product according to the present invention is not limited to any one of the above brake products, but can be suitably used for a disc brake of a vehicle. A vehicle disc brake product is also composed of a plurality of parts. For information management, for example, at least a seal member, a piston member, and a caliper body member among a plurality of parts constituting the brake product are provided. The attribute information it has can be managed. The seal member is assembled to the cylinder in the disc brake, and has a function of sealing the brake fluid between the cylinder and the piston, smoothly operating the piston, and adjusting a constant gap between the rotor and the brake pad. The piston member presses the brake pad by the brake depression force. In the case of an opposed type, the caliper body fixes a brake pad and transmits brake pedal force to the rotor by a built-in piston.

  In the step of attaching attribute information to each of the seal member, the piston member, and the caliper body member and recording the attribute information in a non-contact manner, the attribute information of the seal member, the attribute information of the piston member, and the attribute information of the caliper body Are recorded in the IC tag. The attribute information of the seal member and the attribute information of the piston member are associated with each other and recorded in the IC tag, and the attribute information of the piston member associated with the attribute information of the seal member and the attribute information of the caliper body are associated with each other. You may record on the said IC tag attached to a member.

Information on the brake product can be easily managed by storing it in an IC tag attached to the caliper body member including attribute information of other parts such as brake pads and friction materials. In other words, information can be recorded on the IC tag and information can be read from the IC tag using a reader / writer. However, by using the above method, the IC tag attached to the caliper body member can be used. Since the attribute information of each part constituting the brake product can be acquired simply by reading the information, information management can be easily performed. In addition, when maintenance information or the like included in the attribute information is newly recorded, it is only necessary to record it on an IC tag attached to the caliper body member, so that information management is easier than before. That is, since the piston member and the seal member cannot be visually observed unless they are disassembled, the conventional engraving paint method requires a great amount of labor and cost for information management. However, according to the present invention, it is possible to identify the piston member and the seal member without disassembling, and as a result, information management can be performed more easily than in the past.

  In the information management step, it is preferable to manage the attribute information recorded on the IC tag using a database. When managing attribute information using a database, it is preferable to manage the attribute information of the seal member, the attribute information of the piston member, and the attribute information of the caliper body for each brake product. By managing attribute information using a database, more attribute information can be managed collectively.

  In addition, the present invention can be a brake product having an IC tag that incorporates the features of the invention relating to the brake product management method described above. More specifically, the present invention relates to a brake product having an IC tag, which is composed of a plurality of parts including a seal member, a piston member, and a caliper body member, and environmental resistance of the mounting position. IC tag attached to the caliper body in consideration of information and capable of recording and reading information, identification information provided on the IC tag for identifying the part configuration of the brake product, and quality related to the initial quality of the brake product And a storage device that stores attribute information including at least one of information and maintenance information related to the maintenance history of the brake product.

  According to the brake product having the IC tag according to the present invention, the information management of the brake product can be easily performed by providing the IC tag as compared with the related art. In addition, since the IC tag is attached at a position considering the environmental resistance of the caliper body member, the performance can be sufficiently exhibited even under conditions where the brake product is placed.

  In the brake product having the IC tag according to the present invention, the environmental resistance means at least the degree of temperature increase during brake operation at the position where the IC tag is attached and the degree of influence of damage to the IC tag due to flying stones during traveling. The IC tag includes a part of the caliper body at least one of a position where the temperature rise during braking is small and a position where damage due to flying stones during driving is small. It can be attached to.

Further, the present invention can be a brake product management system for managing a brake product having an IC tag, incorporating the features of the invention relating to the brake product management method and the brake product having an IC tag described above. More specifically, the present invention is a brake product management system for managing a brake product having an IC tag, and includes a plurality of parts including a seal member, a piston member, and a caliper body member, and records information. A brake product having a readable IC tag, a reader / writer for recording the attribute information of the brake product on the IC tag and reading the attribute information from the IC tag, and the reader / writer A management server that is connected via a network and manages the attribute information. The IC tag is attached to the caliper body in consideration of environmental resistance of the attachment position, and the attribute information is the brake product. Identification information for identifying the parts configuration of the vehicle, quality information on the initial quality of the brake product, and maintenance history of the brake product Including at least one of maintenance information, the seal member, the piston member, and the caliper body member each include the attribute information, and the management server includes attribute information of the seal member There is a database that associates the attribute information of the piston member, associates the attribute information of the piston member associated with the attribute information of the seal member, and the attribute information of the caliper body, and manages the information for each brake product.

  According to the present invention, the brake product having the IC tag, the reader / writer that records and reads the attribute information on the IC tag, and the server that manages the attribute information are provided, thereby managing the information on the brake product. It can be done easily.

  In other words, the brake product having the IC tag exhibits the performance of the IC tag because the IC tag is attached to the caliper body in consideration of the environmental resistance at the attachment position. Further, by providing a reader / writer, it is possible to easily record and read attribute information. Note that the reader / writer can be appropriately arranged according to the purpose. Examples of the reader / writer arrangement location include a maintenance shop and a gas station.

  The reader / writer is connected to the management server via a network. Thereby, the attribute information recorded in the IC tag can be managed by the server. As a result, information that cannot be recorded by the IC tag can be collectively managed. By managing the information to be recorded on the IC tag by the server in this way, it is possible to manage various information including the maintenance history, travel usage history, etc. in the market, quality confirmation, traceability, or product development It can be applied to various purposes such as data collection.

  ADVANTAGE OF THE INVENTION According to this invention, the technique regarding a brake product provided with the IC tag which is excellent in environmental resistance and can manage information easily compared with the past can be provided.

  As the IC tag 1, an RFID tag using RFID (Radio Frequency Identification) technology can be used. The type of tag may be either a passive tag (passive tag) or an active tag (active tag), but a passive tag that operates using radio waves from a reader as an energy source and does not need to contain a battery is more suitable. I can say that. This is because it is not necessary to incorporate a battery, can be manufactured at a relatively low cost, and can be used permanently. In addition, according to the active tag, since the radio wave is emitted by itself, the communication distance can be increased.

  Further, examples of the signal transmission method include an electromagnetic induction method and a radio wave method, but any method may be used. According to the electromagnetic induction method of transmitting a signal by magnetically coupling the tag coil and the reader antenna coil, the signal can be transmitted efficiently.
