Kraftöverföringsanordning samt anordning för torsionsavkänning hos kraftöverföringsaxel

摘要

The invention provides a power transmission apparatus which includes a power transmission shaft having a pair of universal joints provided at the opposite ends thereof, and a torsion detection apparatus for detecting a torsion of the power transmission shaft when the power transmission shaft is acted upon by a rotating force. The torsion detection apparatus includes a pair of rotatable members mounted on the power transmission shaft for rotation together with the power transmission shaft and a detection means. The rotatable members have at least one pair of opposing portions which are opposed to each other in a spaced relationship from each other around the power transmission shaft, and the detection means includes a sensor mounted on one of the opposing portions of the rotatable members for detecting an approach of the other opposing portion to the one opposing portion.
