Abstract
(EN) An emergency stop brake operation assembly necessary for a work vehicle when travelling autonomously in an unmanned state is provided in this brake system without introducing problems to manual driving of the work vehicle by an occupant. This brake system for work vehicles comprises: a brake pedal (40) that is disposed in a driving section; a brake that brakes left and right rear wheels; a linkage mechanism (43) that links the brake pedal (40) and the brake in such a manner as to allow the brake pedal (40) and the brake to operate in conjunction with each other; and an electric brake operating device (100) that actuates the brake in response to an emergency stop command. The brake operating device (100) has: an operation-receiving body (101) that is coupled to the brake pedal (40); an electric actuator (102) that operates the operation-receiving body (101); and a clearance-provided section (103) which is located between the brake pedal (40) and the electric actuator (102) and allows displacement of the brake pedal (40) and the linkage mechanism (43) with respect to the electric actuator (102) when the brake pedal (40) is depressed.
(FR) Ensemble d'actionnement de frein d'arrêt d'urgence nécessaire pour un véhicule de travail lorsqu'il se déplace de manière autonome dans un état sans pilote fourni dans ce système de freinage sans introduire de problèmes à la conduite manuelle du véhicule de travail par un occupant. Ce système de freinage pour véhicules de travail comprend : une pédale de frein (40) qui est disposée dans une section d'entraînement ; un frein qui freine les roues arrière gauche et droite ; un mécanisme de liaison (43) qui relie la pédale de frein (40) et le frein de manière à permettre à la pédale de frein (40) et au frein de fonctionner conjointement l'un avec l'autre ; et un dispositif d'actionnement de frein électrique (100) qui actionne le frein en réponse à une instruction d'arrêt d'urgence. Le dispositif d'actionnement de frein (100) comporte : un corps de réception d'opération (101) qui est accouplé à la pédale de frein (40) ; un actionneur électrique (102) qui actionne le corps de réception d'opération (101) ; et une section de dégagement (103) qui est située entre la pédale de frein (40) et l'actionneur électrique (102) et permet le déplacement de la pédale de frein (40) et du mécanisme de liaison (43) par rapport à l'actionneur électrique (102) lorsque la pédale de frein (40) est enfoncée.
(JA) 作業車両の無人状態での自動走行に必要な緊急停止用のブレーキ操作系を、搭乗者による作業車両の手動運転に支障を来たすことなくブレーキシステムに備える。作業車両用のブレーキシステムは、運転部に配置されたブレーキペダル(40)と、左右の後輪を制動するブレーキと、ブレーキペダル(40)とブレーキとを連動可能に連係する連係機構(43)と、緊急停止指令に応じてブレーキを作動させる電動式のブレーキ操作装置(100)とを備え、ブレーキ操作装置(100)は、ブレーキペダル(40)に連結される被操作体(101)と、被操作体(101)を操作する電動アクチュエータ(102)と、ブレーキペダル(40)と電動アクチュエータ(102)との間においてブレーキペダル(40)の踏み込み操作に伴う電動アクチュエータ(102)に対するブレーキペダル(40)及び連係機構(43)の変位を許容する融通部(103)とを有している。
