Transmission for work vehicle

A transmission for a work vehicle that includes a switching clutch for switching to forward and backward movement and a shifting clutch for shifting, the transmission comprising:

• a first shaft having the switching clutch mounted thereon in a housing of the transmission;
• a second shaft rotating forward or backward within the housing, synchronized with the first shaft, and having the shifting clutch mounted thereon;
• a supporting member mounted in the housing and rotatably supporting the first shaft and the second shaft;
• a switching hydraulic valve device mounted on a first wall of the housing close to the switching clutch and controlling the switching clutch;
• and
• a shifting hydraulic valve device mounted on a second wall of the housing close to the shifting clutch and controlling the shifting clutch,
• wherein the switching hydraulic valve device and the shifting hydraulic valve device are connected to the switching clutch and the shifting clutch through channels formed in the supporting member,
• wherein the switching hydraulic valve device is supplied with oil from a hydraulic pump of the transmission, and then transfers the oil to the shifting hydraulic valve device through a connection pipe detouring around the transmission,
• wherein an accumulator is mounted in the path of the connection pipe connecting the switching hydraulic valve device and the shifting hydraulic valve device, in which all the oil from the switching hydraulic valve device passes through the accumulator before the shifting hydraulic valve device, and
• wherein the shifting hydraulic valve device has a manifold structure for transferring oil to different hydraulic devices of the work vehicle.
