Torque detector
First Claim
1. A torque detector comprising:
- (1) a first rotating member adapted for connection to a driving shaft of an internal combustion engine so as to be rotated therewith;
(2) a second rotating member adapted for connection to a load, which is provided so as to be coaxially opposed to said first rotating member;
(3) at least one elastic member for connecting said first rotating member to said second rotating member;
said at least one elastic member deforming in response to torque applied to said first rotating member and producing an angular phase difference between said rotating members due to the deformation thereof;
(4) an angular phase difference detecting means for detecting angular phase difference between said first rotating member and said second rotating member;
(5) a no load condition detecting means for detecting a no load condition of said engine; and
(6) a data processing means for calculating accurate torque from the angular phase difference between said first rotating member and said second rotating member under a load condition and under the no load condition,said no load condition detecting means supplying a no load condition signal to said data processing means when said engine is under the no load condition.

Abstract
A torque detector, for detecting a torque applied to a torque transmission shaft which is connected to a load such as a wheel of an automobile, comprises a first rotating member which is integrally connected to a driving shaft of an engine, a second rotating member which is integrally connected to a load so as to be opposed to the first rotating member, a plurality of elastic members for connecting the opposed surfaces of the first and second rotating members, an angular phase difference detecting circuit for detecting the angular phase difference between the first and second rotating members, a no load condition detecting circuit for detecting a no load condition of the engine, and a data processor for calculating torque from the angular phase difference between the first and second rotating members under the load condition and under the no load condition. An accurate value of applied torque is detected by subtracting the angular phase difference under the no load condition from the load condition.
