摘要： PROBLEM TO BE SOLVED: To provide a low-cost angle detector which effectively uses space in the axial direction of a steering shaft and accurately detects an absolute angle over a lock-to-lock full range of a steering wheel by providing a worm wheel in a reducer with a rotary potentiometer.
SOLUTION: The electric power steering system provides the steering shaft with steering assistance by transmitting the torque of an electric motor through the reducer on the basis of a steering torque detected by a torque sensor. The reducer is provided with the rotary potentiometer. A part of an oscillating arm of the potentiometer engages with a spiral groove provided on the side surface of the worm wheel within the reducer, while providing the oscillating arm with oscillatory rotation according to the rotation of the worm wheel to detect the rotation angle of the steering shaft.

摘要： PURPOSE:To obtain a compact and light-weight torque detector which is capable of analog detection with a simple constitution, by detecting the phase difference between a vertical axis and an original axis which is generated in proportion to the load torque of the vertical axis. CONSTITUTION:When a load torque is applied to a vertical axis 8, a twisted distortion is produced to an elastic member 6. Therefore a phase difference is produced between direct-acting cams 20 and 21, and accordingly a difference of output is produced between linear displacement type potentiometers 23 and 24. The outputs of the meters 23 and 24 produced by the cams 20 and 21 are defined as g1 and g2, and therefore the absolute difference value is detected in the case of figures A and B and can be converted into the torque amount. However, the torque (O) is sometimes recognized erroneously although a torque is actually generated at a certain point since g1 is equal to g2 in case the cams 20 and 21 have a phase shift centering on an inflection point 28 as shown in the figure C. Thus the sum of absolute values of the output difference covering from the output g2 through the point 28 and the output difference covering from the point 28 through the output g1 is converted into a torque amount.
摘要翻译：目的：通过检测与垂直轴的负载转矩成比例地产生的垂直轴和原轴之间的相位差，获得能够以简单结构进行模拟检测的紧凑型重量轻的扭矩检测器。构成：当向垂直轴8施加负载扭矩时，向弹性构件6产生扭转变形，因此在直动凸轮20和21之间产生相位差，因此在线性位移型电位计23和24.由凸轮20和21产生的仪表23和24的输出被定义为g1和g2，因此在图A和B的情况下检测绝对差值，并且可以转换成扭矩量。然而，尽管在某一点实际产生扭矩，但由于在图1中所示的凸轮20和21具有以拐点28为中心的相移的情况下，由于g1等于g2，所以扭矩（O）有时会被错误地识别因此，从输出g2到点28的输出差的绝对值和从点28到输出g1的输出差的总和被转换为转矩量。

摘要： PROBLEM TO BE SOLVED: To provide a torque sensor apparatus and a method used in an automobile steering system.
SOLUTION: The torque sensor apparatus includes a primary shaft coaxially connected to a secondary shaft; and a first substrate operatably connected to the primary shaft oriented approximately perpendicular to an axis defining the shaft. The first and second substrates each have an aperture therethrough configured to receive an alignment pin passing therethrough. The first and second substrates are substantially parallel to each other defining an electrical interface therebetween that is configured to generate a signal indicative of an amount of torque applied to the shaft. A housing is configured to enclose the first and second substrates having the electrical interface therebetween. A one side part of the housing passing therethrough and includes an alignment opening therethrough positioned to align with the openings of the first and second substrates having the alignment pin therethrough extending from an exterior of the housing.
