<p>A front axle suspension (10) for a vehicle that is soft in ride and stiff in roll is provided. The front axle (12) is coupled to a solid beam (16). The beam (16) is a relatively nonflexible member. The beam (16) is pivotally coupled at one end (22) thereof to the frame (14) and is freely movable at the other end (34) thereof, being coupled to said frame through a two-shackle coupling (36,54) that permits vertical displacement and prevents horizontal displacement. Two air bag springs (64 and 66) are coupled between said beam and said frame. In a second embodiment, the spring is J-shaped, having a thick uniform thickness bend short transition sections, a uniformly tapering section, joined to a thinner end of uniform thickness. The bend is closer to the end of the spring secured to the axle than to a second end of the spring coupled to the frame. In a third embodiment, an elongated spring is connected to the pivoted end of the beam and at its opposite end to the frame. A lever surface or beam seat on the beam presses against the undersurface of the spring. The spring is of uniform thickness at the beam seat, tapering uniformly to a constant thickness section at the remote end of the spring.</p> |
