Optimize further: clutch Moving plate is arranged in floating disc housing, half front axle seam is inserted in floating disc housing and is in transmission connection with clutch Moving plate.
Optimize further: floating disc housing is u-shaped structure, clutch Moving plate is positioned close at the opening of floating disc housing and corresponding with clutch price fixing contacts.
Between floating disc housing bottom and clutch Moving plate, brake spring is installed, for resetting to clutch Moving plate.
Optimize further: the portion of external that half front axle seam is located in floating disc housing is set with center, and described brake spring is sleeved on the outside of center.
Clutch price fixing is arranged in fixed disk housing, and rear semiaxis seam is inserted in fixed disk housing and is in transmission connection with clutch price fixing.
Walked together with the drive steering and driving axle of inter-axle shaft and gear clutch by driving change speed gear box to pass through front propeller shaft during machine walking; when gear clutch transships; clutch price fixing and clutch Moving plate can separately rub, and play to the protective effect driving change speed gear box, steering and driving axle and joint transmission axle.
The present invention utilizes the protective effect of gear clutch, and protection drives change speed gear box, steering and driving axle and joint transmission axle, keeps the stability of mechanical 4 wheel driven, reduces the mechanical breakdown of system, extends machine operation time, realize the greatest benefit of machine.
The invention will be further described with reference to the accompanying drawings and examples.
