Description
Technical field
The utility model relates to the mechanical transmission field of sensing technologies.Be specifically related to be applicable to the steel ball/roller push type mechanical torque sensor assembly of rotating speed transmission of motorcycle, electric bicycle.
Background technique
Will realize intelligent transmission control in mechanical transmission, load is important detection index.At present, no matter be on common gearing, still on vehicle, generally be to adopt multiple sensor to obtain relevant parameter respectively to the measurement of this index, comprehensively judge again.As adopt throttle position sensor and speed probe to judge load, promptly so-called a-n system.Wherein, a dactylus valve position, n refers to rotating speed.ECU thinks, the same then load in the position of throttle opening is the same, and the position of throttle opening is different then loads differently, measures with this and to detect the difference of judging load.And for example adopt intake manifold pressure sensor and speed probe to judge load, promptly so-called p-n system.Wherein, p finger pressure power, n refers to rotating speed.Because load variations, suction pressure also can change thereupon, so, differentiate the variation of load, detection load with intake manifold pressure sensor.The oil spout that load difference causes changes by the lambda sensor correction.
