Abstract
An axle suspension particularly applicable to trailers includes an elongated, substantially rigid beam, a pneumatic bellows located at one end of the beam, a hanger bracket located at the other end of the beam, an axle connecting means rigidly connected to the beam and axle, and an elastomeric bushing structure located at or near the pivot connection between hanger bracket and beam which has a different degree of deflection beamwise than hangerwise, is sufficiently rigid to provide suspension stability and is sufficiently resilient to allow operative deflections in response to articulations of the suspension to maintain substantially constant the distance between the hanger bracket and the axle connecting means.
