Abstract
The invention discloses a torque sensor which comprises an input shaft, coils, an output shaft, magnetic pole rings and a sleeve. The output shaft is arranged on one side of the input shaft. The position where the input shaft and the output shaft are connected is sleeved with the sleeve. The magnetic pole rings are arranged on the outer side of the sleeve. The magnetic pole rings are arranged as a group. The torque sensor is simple in structure, stable and reliable in working, small in size and high in accuracy.
Description
Technical field
The present invention relates to a kind of torque sensor.
Background technology
Torque sensor is to measure size that the driver acts on moment on steering wheel and direction, there is a torque sensor can also measure the size and Orientation of steering wheel angle, torque measurement system more complicated and cost are high, so precisely, reliably, torque sensor is to determine one of key factor that can electric boosting steering system dominate the market cheaply.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, provides a kind of easy for installation, simple in structure, the reliable torque sensor of working stability.
Technical scheme: in order to realize above purpose, a kind of torque sensor of the present invention, it comprises: input shaft, coil, output shaft, pole ring and sleeve, one side of input shaft is provided with output shaft, the junction of input shaft and output shaft is arranged with sleeve, and the outside of described sleeve is provided with pole ring, and described pole ring is one group.
Beneficial effect: torque sensor of the present invention, by relatively rotating between input shaft and output shaft, clearance between pole ring changes, thereby cause that electromagnetic inductance changes, and produces induced voltage, thereby converts voltage signal to dtc signal in coil, this torque sensor is simple in structure, working stability is reliable, and volume is little, and precision is high.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in Figure 1, a kind of torque sensor of the present invention, input shaft 1, coil 2, output shaft 3, pole ring 4 and sleeve 5.
One side of input shaft 1 is provided with output shaft 3, the junction of input shaft 1 and output shaft 3 is arranged with sleeve 5, and the outside of described sleeve 5 is provided with one group of pole ring 4, when relatively rotating between input shaft 1 and output shaft 3, clearance between pole ring 4 changes, thereby cause the variation of electromagnetic inductance, in coil 2, produce induced voltage, and convert electrical signals to dtc signal, this torque sensor is simple in structure, working stability is reliable, and volume is little, and precision is high.
Above-mentioned embodiment is only explanation technical conceive of the present invention and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention enforcement according to this, can not limit the scope of the invention with this.All equivalents that Spirit Essence is made according to the present invention or modification, within all should being encompassed in protection scope of the present invention.
