Power transmitting device and vehicle

The invention provides a power transmitting device. The power transmitting device comprises a middle shaft, a torque reaction disc, a guide sector and a sensing device. The torque reaction disc and the middle shaft are perpendicularly arranged on the middle shaft in the axial direction and rotate along the middle shaft; and an axial-direction measuring face horizontally cutting the middle shaft is arranged on the torque reaction disc, the guide sector is arranged on the measuring face, and the sensing device is arranged relatively to the guide sector. When the torque reaction disc is driven by the middle shaft to rotate, the torque reaction disc is deformed by means that torque interlocks the guide sector. The sensing device senses the change of the magnetic permeability generated by deformation of the boot sector, so that the size of the bearing torsion of the middle shaft is judged. 本发明提供种动力传递装置，包含有中轴、扭矩反应盘、导扇区及感测装置。扭矩反应盘与中轴轴向垂直地设置于中轴上，并随中轴转动。扭矩反应盘上具有横切于中轴的轴向的量测面，导扇区布设于该量测面上，而感测装置则相对导扇区设置。当中轴带动扭矩反应盘旋转时，扭矩反应
