A transmission for a work vehicle is provided with: a forward/reverse clutch for switching forward/reverse; and a speed change clutch for changing the speed during driving, and further comprises: a first shaft to which the forward/reverse clutch is mounted; a second shaft that rotates forward or backward in conjunction with the first shaft, and to which a transmission clutch is attached; a support member mounted within the housing to support the first shaft and the second shaft so as to be rotatable; a forward/reverse hydraulic valve device installed on one side wall of the housing adjacent to the forward/reverse clutch to control the forward/reverse clutch; and a speed change hydraulic valve device installed on the other side wall of the housing adjacent to the speed change clutch to control the speed change clutch, in which the forward and reverse hydraulic valve device and the speed change hydraulic valve device may be connected to the forward and reverse clutch and the speed change clutch through an oil passage formed on one support member.
作业车辆用变速器包括:正反离合器,其用于前进/后退切换;以及变速离合器,其用于行驶变速,还包括:第一轴,其安装有正反离合器;第二轴,其与第一轴联动而进行正转或反转,并且安装有变速离合器;支撑构件,其安装在壳体内而支撑第一轴和第二轴可旋转;正反液压阀装置,与正反离合器相邻地安装在壳体的一侧壁上以控制正反离合器;以及变速液压阀装置,其与变速离合器相邻地安装在壳体的另一侧壁上而控制变速离合器,其中,正反液压阀装置和变速液压阀装置可以通过形成在一个支撑构件上的油路连接到正反离合器和变速离合器。
