SPEED REDUCTION SWING ASSIST DEVICE, TOWED VEHICLE, AND CONNECTION VEHICLE

To improve stability when a connection vehicle, in which a towing vehicle and a towed vehicle are swingably connected through a connection part, moves in a swing manner with its speed reduced.SOLUTION: A speed reduction swing assist device includes: brake devices 24R, 24L provided at left and right wheels of a towed vehicle 18 which is swingably connected to a towing vehicle 12 through a connection part 28; and a brake force difference generation part (a rotation member 46, displacement conversion parts 50R, 50L, and a first wire 56 and a second wire 62) which generates a difference between left and right brake forces according to a hitch angle φ with the brake devices 24R, 24L so that the hitch angle φ between the towing vehicle 12 and the towed vehicle 18 is reduced when the towed vehicle 18 swings with its speed reduced in a connected state with the towing vehicle 12.SELECTED DRAWING: Figure 5 【課題】連結部を介して牽引車両と被牽引車両とが揺動可能に連結された連結車両の減速旋回時の安定性を向上させる。【解決手段】連結部２８を介して牽引車両１２と揺動可能に連結される被牽引車両１８の左右の車輪に設けられた制動装置２４Ｒ、２４Ｌと、被牽引車両１８が牽引車両１２と連結された状態での減速旋回時に、牽引車両１２と被牽引車両１８とのヒッチ角φが減少するように、制動装置２４Ｒ、２４Ｌでヒッチ角φに応じた左右の制動力差を発生させる制動力差発生部（回動部材４６、変位変換部５０Ｒ、５０Ｌ、第１ワイヤ５６および第２ワイヤ６２）と、を含んでいる。【選択図】図５
