Suspended chassis for agricultural machine

摘要

The agricultural vehicle suspended chassis (1) comprises a frame (2) which is supported at its two ends by a first axle (7a) connecting two wheels (8a) and by a rolling support. The first axle is rigidly fixed to a first swingle bar (10a) freely rotating on the frame about a spindle (12a) transverse to the frame forward direction and displaced upwards relative to the wheel axles. A first suspension (15a) is interposed between the swingle bar and the frame. The rolling support is constituted by a second axle (7b) which connects two wheels (8b) and freely rotates on a second swingle bar (10b) about a central spindle (11b) parallel to the forward movement of the frame. This second swingle bar rotates freely on the frame about a spindle (12b) transverse to the frame forward movement and displaced upwards and towards the front of the frame relative to second wheel axles. The second suspension (15b) is interposed between the frame and the second swingle bar.
