Transfer case of full-hydraulic bulldozer

The utility model relates to a transfer case of a full-hydraulic bulldozer. The rubber coupling comprises a coupling outer hub, a coupling inner hub and a rubber block. The coupler inner hub and the coupler outer hub are connected through a middle rubber block. The coupling inner hub is connected with the transfer case input shaft through a spline; the coupling outer hub is connected with an engine flywheel; the other end of the input shaft is fixedly connected with the driving gear; the driving gear is rotationally installed on the box body through a cylindrical roller bearing II, the workinghydraulic pump is installed on the outer wall of the closed end of the box body, a power input shaft of the working hydraulic pump penetrates through the box body to be connected with the driving gear through a spline, and a driven gear I and a driven gear II which are meshed with the driving gear are further arranged in the box body. The transfer case has the advantages that the transfer case adopts an integral case bod
