The invention relates to a torque sensor for an electric bicycle system. The torque sensor may include a support that may be disposed around a device of the bicycle such that the support and the device of the bicycle are separated by an air gap. The torque sensor may also include an excitation coil supported by the support and a sensing coil supported by the support at a distance from the excitation coil in an axial direction of the support. The excitation coil is configured to induce a voltage and/or current in a sensing coil via a device of a bicycle when the support is disposed around the device of the bicycle. The induced voltage is related to a torque in the device.
本发明涉及一种用于电动自行车系统的扭矩传感器。所述扭矩传感器可包括支撑件,所述支撑件可围绕所述自行车的装置设置,使得所述支撑件和所述自行车的所述装置通过气隙分开。所述扭矩传感器还可包括由所述支撑件支撑的激励线圈以及在所述支撑件的轴向方向上远离所述激励线圈一段距离处由所述支撑件支撑的感测线圈。所述激励线圈被配置为当所述支撑件围绕自行车的装置设置时经由所述自行车的所述装置在感测线圈中感应出电压和/或电流。所感应出的电压与装置中的扭矩有关。
