Abstract
This device comprises an arm (15) for supporting the load, such as a roller member of a vehicle, articulated about a bearing axle (2), together with a resilient leaf (1) forming a spiral about the axle (2) and a cushioning strip (12) of an elastomeric material interposed between two consecutive turns (1c, 1d, 1e) of the leaf (1); the inner end of the leaf (1) is rigidly fixed to the bearing axle (2) and its outer end (1b) is fixed to the arm (15), these resilient members (1, 12) preferably being accommodated within the arm (15) in a leaktight housing 15a). Cooling element (14, 26) including a liquid which fills the housing (15a) to ensure the cooling of the suspension. The latter is entirely independent and of minimum bulk, and can be used in any terrain by virtue of the cooling element.
