Title:
SUSPENSION FOR WHEEL SHOVEL
Document Type and Number:
Japanese Patent JP3623385
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To smoothly vertically move and swivel an axle relative to a frame, while absorbing a shock from the axle.
SOLUTION: A pair of brackets 3 is mounted to be separated to the front/ rear on right/left side surfaces of a frame 87. A protrusion part 2t is provided before/behind a cylinder tube of a hydraulic cylinder 2, and this protrusion part 2t is turnably inserted to an opening part 3a of the bracket 3. One side (left side) of the frame 87, one end of a link 4, and the center of an axle 1, the other end of the link 4, are turnably connected respectively through pins 93, 94. The frame 87 and the axle 1 are thus connected by the right/left hydraulic cylinders 2, so as to absorb a shock of vertical movement and swiveling from the axle 1, and by connecting the frame 87 and the axle 1 by the link 4, movement of the axle 1 relative to the frame 87 is smoothed.
