TORQUE SENSOR
A torque sensor (200) includes a sensor unit (222), a resilient body (213), and a detection unit (223). The sensor unit (222) detects, from an output unit that is a rotational body of an actuator, a rotational position in an annular first area positioned at a first distance from a rotation center, and a rotational position in an annular second area positioned at a second distance longer than the first distance from the rotation center. The resilient body (213) is provided between the first area and the second area. The detection unit (223) detects a torque applied to the output unit, on the basis of a result of the detection by the sensor unit (222).
Power-output torque detection mechanism
A power-output torque detection mechanism includes an axle having two ends to which an input assembly and an output assembly drivable by the input assembly are respectively mounted. A torsion coupling assembly is arranged between the input assembly and the output assembly and the torsion coupling assembly is operable to detect a torque value that is transmitted out in a wired manner. As such, it is possible to fulfill fine and precise detection and transmission of a torque value, while avoiding distortion resulting from noise interference to allow subsequent input of assisting power to be more timely and more accurate. Further, the structure is effectively simplified to allow easy production and maintenance for further reducing overall cost.

Torque meter shaft with rotational slip enabled sensor indicating tabs
A torque meter shaft that includes a hollow tube, a ring with ring tabs, the ring enveloping the hollow tube, a shaft with shaft tabs and a deformable section, the shaft disposed within the hollow tube such that the ring tabs and the shaft tabs correspond forming an inter-locking non-contact fit, and a first spline coupling and a second spline coupling. The first spline coupling communicates with an engine such that torque from the engine is transferred to the deformable section and elastically deforms when torque is applied to the first spline coupling and the shaft tabs change radial position relative to the position of the ring tabs such that relative change in torque can be measured, and when torque results in creating a shaft deformation that passes the material yield point, the ring tabs and shaft tabs contact each other, and the ring tabs are pushed back into a new position that compensates for the shaft deformation allowing the engine to maintain its full power capacity.
