The invention discloses a wide-rotation speed range and multi-induction source transmission device and belongs to the technical field of automobile transmission. The wide-rotation speed range and multi-induction source transmission device is mainly used for solving the problem that the full rotation speed range performance test of the engine sensor cannot be carried out by the traditional sensing device. The wide-rotation speed range and multi-induction source transmission device is mainly characterized by comprising a bottom plate, a motor support, a frequency conversion motor, a support plate, a bearing pedestal holder and an end face adjusting component stand, wherein a first bearing and a flywheel shaft are arranged between an upper support plate and a lower support plate in the support plate; a lower bearing pedestal, an upper bearing pedestal and a second bearing are arranged on the bearing pedestal holder; one end of the flywheel shaft is linked with the frequency conversion motor, and the other end of the flywheel shaft is provided with a gear and an end face flywheel; an elastic cylindrical pin, a shaft and an end cover are arranged in the second bearing; an end face adjusting component and a radial adjusting component are arranged on the end face adjusting component stand. The full rotation speed range performance test of the engine sensor can be carried out by the wide-rotation speed range and multi-induction source transmission device, and the wide-rotation speed range and multi-induction source transmission device also has the characteristic of high rotation speed precision. The wide-rotation speed range and multi-induction source transmission device is mainly used for performance test of various rotation type sensors of the automobile.
