Patent ID: 7722063

Claim:
A suspension system for a tilting vehicular chassis, comprising: a non-tilting frame of longitudinal extent having a first axis and a plurality of first horizontal members, the first horizontal members rotatably attached in oppositely-disposed pairs about the first axis at least at each end, the non-tilting frame supporting at least a means for motorizing; a tilting frame of longitudinal extent rotatably attached to the non-tilting frame about the first axis, the tilting frame having a second axis parallel to the first axis and a plurality of second horizontal members, the second horizontal members rotatably attached in oppositely-disposed pairs about the second axis, each second horizontal member rotatably attached to a corresponding first horizontal member by a vertical strut, the tilting frame supporting at least one occupant; a plurality of road-contact wheels rotatably attached to the vertical struts, at least one wheel of which is connected to the means for motorizing; and a means for suspending the paired first horizontal members to ride level with the road while providing for a smooth ride by absorbing road surface irregularities in the articulating recoil of individual wheels.
