Problems solved by technology

[0005] However, it is necessary to disassemble the device and observe from the joint part (knuckle), etc. to know the manufacturing number, manufacturing year, manufacturing location and other information marked on the wheel bearing device by engraving, etc.
Therefore, disassembly and reassembly take time
It may not be confirmed by engraving due to corrosion or deterioration of the periphery due to long-term use
[0006] In addition, in information recording by engraving, the amount of information that can be recorded is limited, and it is difficult to adequately manage
Therefore, it is necessary to check with a computer or account book for management, and this check takes time
For a large number of wheel bearing devices, it is also difficult to record and manage the manufacturing information of each wheel bearing device in detail in terms of retrieval time, etc.

Embodiment Construction

[0046] A first embodiment of the present invention will be described with reference to FIG. 1 . This wheel bearing device 1 is a third-generation inner wheel rotation type, and is an example for supporting a driving wheel. In addition, in this specification, the side closer to the outer side in the vehicle width direction of the vehicle in the state mounted on the vehicle is called the outer side, and the side closer to the center in the vehicle width direction is called the inner side. In Figure 1, the left side is the outer side and the right side is the inner side.

[0047] This wheel bearing device 1 has: an outer member 31 having a plurality of rows of raceway surfaces 35 on the inner periphery; an inner member 32 having a raceway surface 36 opposed to the raceway surface 35; and a plurality of rows of rotating bodies 33. Between the opposite track surfaces 35 , 36 of the outer and inner parts 31 , 32 . Both ends of the bearing space between the outer member 31 and the ...

Abstract

An IC tag (9) capable of contactless communication is affixed on any one or more of element parts constructing the bearing device (1) for the wheel. For example, the IC tag is affixed on a forging forming an outer member (31) or an inner member (32). The place of installation of IC tag is preferably chosen to be a surface of the forged component part which is not machined subsequent to forging.

Description

technical field [0001] The present invention relates to a wheel bearing device equipped with IC tags such as RFID tags. Background technique [0002] IC tags using RFID (Radio Frequency Identification) technology that can communicate in a non-contact state continue to be miniaturized and are widely used in logistics. In addition, the following technology has been proposed in recent years: In recent years, the demand for traceability, that is, the request for tracking the history, application, or location of the component under consideration has gradually increased, and IC tags are attached to gears and other various equipment components. , to store and manage the ID code or various information related thereto (for example, refer to JP-A-2002-049900). [0003] Since the wheel bearing device is a running part of an automobile, after use, it is necessary to know a large amount of identification information or historical record information at the time of periodic inspection or ...
