Patent number: 7229094Abstract: A tandem axle suspension assembly includes a pair of walking beams disposed substantially parallel to a vehicle longitudinal axis supporting first and second axles. A link plate is pivotally attached to each of the walking beams and is pivotal about an axis transverse to the longitudinal axis. A first and a second link include pivotal connections between the link plate and a vehicle frame member. Vertical movement of the walking beams causes a corresponding rotation of the link plate to compensate for longitudinal displacement of the pivotal links with the first and second links and minimize longitudinal displacement of the walking beams.Type: GrantFiled: May 25, 2004Date of Patent: June 12, 2007Assignee: ArvinMeritor Technology, LLCInventors: Steven R.
