Abstract
An inter-axle differential capable of preventing a skid to achieve stable travel is provided. For this purpose, the inter-axle differential apparatus includes an inter-axle differential (13), an inter-axle differential lock (21), at least one rotation detector of a first rotation detector (27) for detecting rotational frequency of a transmission output shaft (24), a second rotation detector (28) for detecting rotational frequency of a front output shaft (25) of the inter-axle differential, and a third rotation detector (29) for detecting rotational frequency of a rear output shaft (26) of the inter-axle differential, and a controller (20) for detecting a sign of a skid occurring to driving wheels (2, 4) based on at least any one of the rotational frequency detected by the rotational detector and a rate of change with time of the detected rotational frequency and for outputting a differential lock signal to the inter-axle differential lock.
