SUPPORT STRUCTURE FOR ROTATION SPEED SENSORS

摘要

An differential apparatus according to the present invention includes a ring gear and a sensor for detecting the rotation speed of the ring gear. One side of the ring gear has a plurality of teeth. The sensor detects the teeth passing by the sensor when the ring gear rotates. Each tooth has an outer end surface that is parallel to the rotation axis of the ring gear. The sensor is spaced from the gear and radially faces the axis of the gear.
