摘要: A differential gear assembly (1) comprises: a disc-shaped input gear (2) receiving drive force and having a central portion (9), an outer portion around the central portion, and one or more open space portions (2a,2b,2c), formed between the central portion and the outer portion; a pair of output shafts (3,3') extending in opposite directions along the axis of the input gear (2) and one end of each of the output shafts being loosely fitted in a central bore (9A) formed in the central portion of the input gear; a pair of side bevel gears (4,4') each of which is fixedly attached near the end of each output shaft (3,3') closer to the input gear; one or more support shafts (9B,9B') extending radially from the central portion into the open space portions of the input gear; one or more bevel pinions (5,5') rotatably supported on the one or more support shafts, respectively, to mesh with the pair of side bevel gears; and friction mechanism (6,6',7,7',8,8') located in at least one of said one or more open space portions that permits the bevel pinion to rotate with rotational resistance. A limited slip effect is provided without using a casing-shaped ring gear, whereby the resulting assembly can be compact and less costly.
