    Abstract: In order to inexpensively measure torque on a shaft such that the measurement is as independent as possible from distance changes or material inconsistencies of the shaft around the circumference thereof, the invention provides a torque transmitter (10) for a torque sensor (12) for measuring a torque on a shaft (14), having a carrier plate (34) that has a plurality of sensor element carrier plate regions (38), on each of which at least one sensor element (18) for recording magnetic field changes, caused by the magnetoelastic effect, is arranged, and at least one enclosure region (16) that is designed to at least partly enclose the shaft (14) around the circumference of the shaft (14), wherein at least one flexible connection region (40) is provided by way of which at least one of the sensor element carrier plate regions (38) is able to be pivoted relative to another sensor element carrier plate region (38) or relative to the at least one enclosure region (16).

    Abstract: An actuator assembly with integrated torque turn monitoring is described. Embodiments include a rotationally fixed outer hydraulic section and a rotationally independent inner hydraulic section which incorporates torque load sensors, axial load sensors, and rotational speed sensors directly into the inner hydraulic section. The inner hydraulic section is coupled to an outer cage by a cage ring and is axially movable relative to the inner mandrel. Upper and lower fluid chambers are disposed between the outer housing assembly and the inner mandrel. Fluid pumped through a lower pressure port into the lower chamber moves the housing assembly in a first direction, and fluid pumped through an upper pressure port into the upper fluid chamber moves the housing assembly in a second direction.

    Abstract: A system for measuring torque on a component having a residually magnetized region is provided. The system includes a torque sensor for sensing an electromagnetic characteristic of the component and transmitting a plurality of signals that are indicative of the electromagnetic characteristic. The system also includes a computer communicatively coupled to the torque sensor for receiving the signals. The computer includes a processor and a memory. The processor is programmed to determine, using the signals, that the torque sensor is affected by the residually magnetized region of the component.

    Abstract: A torque detection device that further suppresses intrusion of foreign matter into a magnetism collection holder. A first magnetism collection holder has a first ring portion and a substrate housing portion. A second magnetism collection holder has a second ring portion and a substrate housing portion. A pair of flanges are provided on both side surfaces of the substrate housing portion. The substrate housing portion is provided with a partition wall to be fitted between the flanges. A substrate arrangement portion is provided with a partitioning portion and an extended portion. When the substrate housing portion and the substrate housing portion are stacked on each other, the extended portion is fitted with a recessed portion. The substrate arrangement portion is also provided with a partitioning portion. An extended portion to be fitted with the recessed portion is provided at the distal end of the partitioning portion.

    Abstract: A torque sensor chip including a semiconductor substrate, an acoustic reflector formed on the semiconductor substrate, and first and second Lamb wave resonators (LWRs). The first LWR is formed on a side of the acoustic reflector opposite the semiconductor substrate. The first LWR is at a first angle with respect to an axis of the IC. The second LWR also is formed on the side of the acoustic reflector opposite the semiconductor substrate. The second LWR is at a second angle, different than the first angle, with respect to the axis of the IC.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
