Document Type and Number:
Japanese Patent JP2017047837
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wheel fastening state determination device which can accurately determine the fastening quality of a wheel fastening part at the attachment of a wheel and the maintenance of a vehicle, in which a component which is constantly arranged at the wheel for determining a fastening state is compact in size while being enabled in the precise detection of distortion, and which can minimum an influence to the vehicle.SOLUTION: A wheel fastening state determination device comprises a space-type sensor unit 3, fastening state determination means 5, and fastening torque measurement means 20 which is added to a fastening tool 19 such as a torque wrench. The sensor unit 3 comprises a ring-shaped spacer-shaped member 12 for generating deformation, and a strain sensor 13 which are interposed over the whole periphery of a wheel between a head part of each hub bolt for attaching the wheel to the hub and a wheel nut. The fastening state determination means 5 is arranged at an information processor 4 such as a portable terminal. The fastening state determination means 5 determines a fastening state by using the information of the strain of the strain sensor 13, and fastening torque which is detected by the fastening torque measurement means 20.SELECTED DRAWING: Figure 1
