PROBLEM TO BE SOLVED: To provide a differential limiting device of a four-wheel drive vehicle, which can be largely downsized in a width direction and reduced in weight.SOLUTION: A two-way clutch 40 that performs switching between four-wheel drive and two-wheel drive and a dog clutch 60 for a differential lock of a differential 9 are provided at a side part of the differential 9 which distributes drive torque from a propeller shaft 7 to a pair of left and right axle shafts 11a and 11b. The differential 9 is a planetary gear type one configured to have: a carrier 16 fixed to an input-side ring gear 15; a pinion gear 17 supported rotatably to the carrier 16; a sun gear 18 for outputting distribution torque which is supported to one end part of a torque transmission shaft 26 assembled coaxially between the pair of axle shafts 11a and 11b and engaged with the pinion gear 17; and an output-side ring gear 19 for outputting distribution torque which is provided at a shaft end part of the other axle shaft 11a and engaged with the pinion gear 17, so as to be largely downsized in a width direction and reduced in weight.SELECTED DRAWING: Figure 2
【課題】幅方向の大幅なサイズダウンと重量の低減を図ることができるようにした四輪駆動車の差動制限装置を提供することである。【解決手段】プロペラシャフト7からの駆動トルクを左右一対のアクスルシャフト11a、11bに分配するディファレンシャル9の側部に四輪駆動と二輪駆動の切換えを行う二方向クラッチ40と、ディファレンシャル9のデフロック用のドグクラッチ60とを設ける。ディファレンシャル9が、入力側リングギヤ15に固定されたキャリヤ16と、そのキャリヤ16に回転自在に支持されたピニオンギヤ17と、一対のアクスルシャフト11a、11b間において同軸上に組み込まれたトルク伝達軸26の一端部に支持されてピニオンギヤ17と噛合する分配トルク出力用のサンギヤ18と、他方のアクスルシャフト11aの軸端部に設けられてピニオンギヤ17に噛合する分配トルク出力用の出力側リングギヤ19を有してなる遊星歯車式のものとして幅方向の大幅なサイズダウンと重量の低減を図る。【選択図】図2
