Go out to hold the input of the engine clutch assembly that is connected；The corresponding outfan transmission of the engine clutch assembly
Connect the input of the blower fan centrifugal clutch, the outfan of the blower fan centrifugal clutch blower fan that is connected is driven
Wheel, the blower fan driven pulley are assemblied on the input of the blower fan；The corresponding outfan of the engine clutch assembly is passed
The dynamic input for connecting the high-pressure hydraulic pump Pneumatic power diaphragm type clutch, the output of the high-pressure hydraulic pump Pneumatic power diaphragm type clutch
The high-pressure hydraulic pump driven pulley that is connected, the high-pressure hydraulic pump driven pulley is held to be assemblied in the input of the high-pressure hydraulic pump.
The outfan of the blower fan centrifugal clutch is connected the blower fan driven pulley by blower fan driving belt.
The outfan of the high-pressure hydraulic pump Pneumatic power diaphragm type clutch is connected described by high-pressure hydraulic pump driving belt
High-pressure hydraulic pump driven pulley.
After said structure, this utility model has the advantages that：
When the 1st, changing engine start, blower fan drivewheel is changed to one by original belt pulley by the mode of blower fan moment loading
Plant brand-new clutch --- blower fan centrifugal clutch.
2nd, change the pneumatic gear clutch pattern of high-pressure water pump clutch, using high-pressure hydraulic pump pneumatic diaphragm clutch, tooth
Formula clutch cannot realize the combination under rotating speed, and diaphragm clutch can be realized the quick combination under any state, subtract significantly
The use condition for having lacked high-pressure hydraulic pump requires the operation difficulty with workman.
