Therefore, a transfer case is needed to provide installation space for the main pump, increase the speed and reduce the engine speed. The layout of large-displacement engine, transfer case and four main pumps causes the sprung mass of the suspension system to reach four or five tons, which places very high demands on the engine support and its shock absorbers. The engine and transfer case are connected through the flywheel housing and the transfer case housing. The traditional four-point installation on the engine or transfer case housing layout, the flywheel housing strength and rigidity can no longer meet the requirements. Utility Model Content

[0011] This structure has high mechanical strength and improves the rigidity of the system.

[0012] Preferably, the transfer case mounting plate is in an L-shape, with a width of a lower portion being greater than a width of an upper portion.

[0013] When in use, the notch on the upper part of the transfer case mounting plate facilitates the arrangement of the engine support.

[0014] Preferably, the engine support comprises an engine mounting plate, the cross-section of the engine mounting plate is L-shaped, the outer side of the engine mounting plate is a processed surface, the processed surface of one side plate of the engine mounting plate is connected to the vertical plate, and the processed surface of the other side plate of the engine mounting plate is connected to the flywheel mounting surface.
