Beschreibung
Zusammenfassung:	Provided is a transmission of a work vehicle, comprising a forward/reverse clutch for forward/backward switching and a gear shift clutch for shifting gears during driving, the transmission comprising: a first shaft to which the forward/reverse clutch is mounted; a second shaft which rotates forward or reverse in conjunction with the first shaft and to which the gear shift clutch is mounted; a support member mounted in a housing and rotatably supporting the first shaft and the second shaft; a forward/reverse gear shift hydraulic valve device mounted on one sidewall of the housing adjacent to the forward/reverse clutch and controlling the forward/reverse clutch; and a gear shift hydraulic valve device mounted on the other sidewall of the housing adjacent to the gear shift clutch and controlling the gear shift clutch, wherein the forward/reverse gear shift hydraulic valve device and the gear shift hydraulic valve device may be respectively connected to the forward/reverse clutch and the gear shift clutch through flow passages formed in the one support member. L'invention concerne une transmission d'un véhicule de travail, comprenant un embrayage avant/arrière pour une commutation avant/arrière et un embrayage de changement de vitesse pour le changement de vitesse pendant la conduite, la transmission comprenant: un premier arbre auquel est monté l'embrayage avant/arrière; un second arbre qui tourne vers l'avant ou vers l'arrière conjointement avec le premier arbre et auquel est monté l'embrayage de changement de vitesse; un élément de support monté dans un boîtier et assurant le support rotatif du premier arbre et du second arbre; un dispositif de soupape hydraulique de changement de vitesse avant/arrière monté sur une paroi latérale du boîtier adjacente à l'embrayage avant/arrière et effectuant la commande de l'embrayage avant/arrière; et un dispositif de soupape hydraulique de changement de vitesse monté sur l'autre paroi latérale du boîtier adjacente à l'embrayage de changement de vitesse et effectuant la commande de l'embrayage de changement de vitesse, le dispositif de soupape hydraulique de changement de vitesse avant/arrière et le dispositif de soupape hydraulique de changement de vitesse pouvant être respectivement reliés à l'embrayage avant/arrière et à l'embrayage de changement de vitesse par des passages d'écoulement formés dans l'élément de support. 전후진 전환을 위한 정역 클러치 및 주행 변속을 위한 변속 클러치를 포함하는 작업 차량의 트랜스미션은, 정역 클러치가 장착되는 제1 축, 제1 축과의 연동하여 정회전 또는 역회전을
