Abstract
A torque detection arrangement for a vehicle driven by muscle power has an input shaft via which a torque for driving the vehicle can be transmitted. The torque is to be detected. At least one rotary member is mounted on the input shaft and is designed to transmit the torque. The input shaft and the rotary member are resiliently connected in the rotational direction via a torsion spring arrangement. A twisting angle detection arrangement is designed to detect a rotation of the rotary member relative to the input shaft. The input shaft is designed as a hollow shaft. A torsion spring of the torsion spring arrangement is arranged inside the hollow input shaft.
