摘要： A bicycle having a rear wheel including an axle, a hub shell, a torque element including a torque output portion and a torque input portion, and a rear cog coupled to the torque input portion. The torque output portion is a first radial distance from the torque input portion. The position sensor measures a rotational position of the torque input portion relative to the torque output portion. In one embodiment, the position sensor includes a displacement indicator (e.g., a radial tab mounted to the torque output portion) and a displacement sensor (e.g., an inductive sensor mounted to the torque input portion). The inductive sensor preferably has two sensing coils positioned on each side of the displacement indicator. The hub assembly can further comprise a wireless transmitter adapted to transmit data from the position sensor. The hub shell preferably includes a window that facilitates data transmission from the wireless transmitter.

摘要： A magneto-elastically-based active force sensor, used with a tow coupling between a towed and a towing vehicle, which outputs a signal useful for determining forces acting on the coupling. The outputted force information may be provided by processor-enabled embedded software algorithms that take inputs from the force sensor and other sensors, may be used by one or more vehicle systems during operating of the vehicle, such as engine, braking, stability, safety, and informational systems. The force sensor includes directionally-sensitive magnetic field sensing elements inside the sensor, and shielding may be used around the sensors to reduce the influence of external magnetic fields on the sensing elements. The force sensor may be used with different tow coupling devices installed on different types of automobile cars and trucks.

摘要： A vehicle steering apparatus. The durability of a sensor rotor to heat and abrasion is improved. The flatness of the sensor rotor is prevented from being lowered during calking for coupling of the sensor rotor to a steering shaft so that steering torque of a driver can be more accurately detected. A fabrication process is simplified, and fabrication costs are reduced.

摘要： A sensor device that can suppress positional fluctuations of a sensor element with first and second magnetism collection portions due to injection molding of a housing is provided. A housing of a torque sensor has a ring portion cover portion that surrounds and holds a first ring portion of a first magnetism collection ring and a second ring portion of a second magnetism collection ring, and a sensor cover portion that houses a first magnetism collection portion, a second magnetism collection portion, and a sensor unit. The sensor cover portion extends toward the radially outer side from the ring portion cover portion. The sensor cover portion has a sensor housing portion that houses the sensor unit as interposed between the first magnetism collection portion and the second magnetism collection portion, an opening portion that opens in the axial direction, and a lid portion that closes the opening portion.

摘要： A sensor device that can suppress deformation of a holder due to a molding pressure applied during injection molding of a housing is provided. A second magnetism collection portion holder has a suppression portion that projects from a second holder body portion toward a first holder and that suppresses deformation of the holder due to the molding pressure applied during the injection molding. The distal end surface of the suppression portion abuts against the inner surface of a first holder body portion with the first holder and a second holder assembled to each other with a sensor unit interposed therebetween.

摘要： A torque sensor includes: an annular deformation body; first and second displacement electrodes which cause displacement by elastic deformation of the annular deformation body; first and second fixed electrodes arranged at positions opposite the first and second displacement electrodes; and a detection circuit that outputs an electric signal indicating a torque based on a variation amount of capacitance values of first and second capacitive elements each of which is configured of the displacement electrode and the fixed electrode. The annular deformation body includes a high elastic portion and a low elastic portion having a spring constant smaller than a spring constant of the high elastic portion. The detection circuit determines whether the torque sensor functions normally based on a ratio between first and second electric signals.

摘要： A magnetostrictive torque sensor is provided that is capable of maintaining high detection accuracy, even when an excessive torque acts on a rotary shaft. The magnetostrictive torque sensor includes a magnetostrictive film 71 that is arranged on a second steering shaft 23, or a rotary shaft, having a substantially columnar shape so as to surround the second steering shaft 23 around its axis, and detects a rotational torque about the axis acting on the second steering shaft 23 based on a change in a magnetic property of the magnetostrictive film 71. Compressive stress remains on an outer circumferential surface of a sensor region 77 of the second steering shaft 23 around which the magnetostrictive film 71 is arranged. A plated layer of the magnetostrictive film 71 is arranged on the outer circumferential surface of the sensor region 77 in which compressive stress remains.
