STEERING AXLE FOR A VEHICLE HAVING TWO LATERALLY TILTABLE FRONT WHEELS

摘要

The invention concerns an undercarriage (35) for a vehicle comprising a chassis, two front steering wheels (36D, 36G) and at least one rear drive wheel. The undercarriage comprises, combined with each wheel, a suspension system (39) suspending the wheel from said chassis, said system (39) comprising an upper suspension arm (40), a lower suspension arm (41) and a lateral arm (42), said arms being linked together by articulated means (43, 44, 45, 46) such that a lateral tilting of the undercarriage results in an equivalent tilting of the two front wheels, which remain parallel to each other. According to a feature of the invention, the undercarriage comprises a damper (50), integral with each front wheel, to at least partially cancel the oscillation frequencies of said front wheel.
