<p>The present invention provides a torque detection device and a bicycle with the same. The invention discloses the torque detection device and aims to provide the torque detection device which has the advantages of simple structure and easy miniaturization. The torque detection device is characterized in that: the torque detection device is composed of an annular magnet, a first annular magnetic yoke, a second annular magnetic yoke and a magnet sensor. On the annular magnet, S poles and N poles are alternately magnetized along a circumferential direction. The first magnetic yoke is provided with the following components: tooth-shaped first magnetized parts which respectively oppose S poles of the magnet and are arranged to a ring shape, and a first annular board which is formed to an annular shape in a manner of connecting each first magnetized part. The second magnet yoke is provided with the following components: tooth-shaped second magnetized parts which respectively oppose N poles of the magnet and are arranged to an annular shape, and a second annular board which forms an annular shape in a manner of connecting each second magnetized part and is configured in a face-to-face manner with the first annular board. A magnetic sensor is configured between the first annular board and the second annular board.</p> |
