Abstract: First and second encoders are fixed to a drive plate and a clutch cover of which the center portions are connected to each other via a connection shaft and which are disposed between, in a transfer path for torque outputted from an engine, a damper and a connecting/disconnecting part of a clutch mechanism of a transmission. At the same time, detection units of first and second sensors are opposed to portions to be detected of the first and second encoders, respectively.

Abstract: A charger incorporated in a vehicle wheel supporting rolling bearing unit detects an output voltage of an electric generator and calculates a rotation speed of a hub. When a rotation speed of the hub is in a low speed state where a sensor and a wireless communication device are operated by electric power supplied by a battery, a frequency of wireless communication performed between the wireless communication device and a calculator disposed on a vehicle body side is changed according to the rotation speed of the hub or a traveling speed of a vehicle.

Abstract: A wheel equipped with a sensing device includes a wheel and a sensing device. The sensing device includes a displacement extraction member, a to-be-detected part, and a detecting part. One radial end portion of the displacement extraction member is supported to one radial end-side portion of the wheel. The other radial end portion of the displacement extraction member is a free end. The to-be-detected part is provided to one of the other radial end-side portion of the wheel and the other radial end portion of the displacement extraction member. The detecting part is provided to the other of the other radial end-side portion of the wheel and the other radial end portion of the displacement extraction member, and is arranged in a vicinity of the to-be-detected part. An output of the detecting part changes in association with a change in positional relationship between the detecting part and the to-be-detected part.

Abstract: The present invention provides a rolling bearing unit for supporting wheel that is able to suppress increase in the dimension in the axial direction due to the installation of a generator and a wireless communication apparatus to a minimum, supply sufficient electric power to a sensor attached to a wheel, and wirelessly transmit output signals of the sensor to an electronic apparatus on the vehicle body. The hub 17 comprises an inner recessed portion 29 on the inner diameter side of the inside portion in the axial direction which has a cylindrical fitting surface section 30 on the inner peripheral surface and is coaxial with the center axis of the hub 17, and a supporting member 67 is supported by and fastened to the inside of the inner recessed portion in a state where the hollow cylindrical supporting member 67 fits the cylindrical guide surface section 70 that is provided in the outer peripheral surface to the fitting surface section 30. A rotor 6 which is an armature is fixed to the inside portion in the axial direction of the supporting member 67 to be coaxial with the supporting member 67, and the wireless communication apparatus 12 is placed inside in the radial direction of the supporting member 67. A through-hole 34 where a wiring 57 is placed opens in the bottom surface 31 of the inner recessed portion 29.

Abstract: A vehicle weight measurement device includes an annular diaphragm (11) configured to cover an opening area (9d) of a groove portion (9c) of a mounting part (7) and to form a predetermined oil chamber (9) together with the groove portion. The diaphragm (11) is hermetically fixed by an inner collar (33) and an outer collar (35). The diaphragm (11) is pressed by a piston (43) configured to be moveable by a resilient force of a spring of a suspension device, and a pressure of a fluid to be measured R filled in the oil chamber, which is to be applied by the movement of the piston, can change. A pressure sensor (21) configured to communicate with the oil chamber and to detect a change in pressure of the fluid to be measured R filled in the oil chamber is provided.
