Abstract: A vibration eliminating mount for supporting a load is disclosed herein having a three point suspension wherein each of the three points includes a pair of angularly disposed brackets secured to the load and the support respectively. Carried between opposing parallel surfaces on the brackets is a fluid vibration eliminating assembly movably separating the pair of brackets. The assembly is carried in a dish or pan which is fixedly secured to at least one of the brackets and provision is made for accommodating a fluid valve for suitably pressurizing the assembly.

Abstract: A chassis for a heavy duty vehicle is disclosed herein having an elongated box frame supported on an undercarriage of articulated wheel sets. The undercarriage includes a front wheel set carried on one end of the frame by a pivoting torque box having trailing pivotal arms for rotatably supporting the front wheels. A pair of rear wheel sets include a pair of wheel axles carried on trailing arms and controlled by a walking beam assembly and having shock-absorbers and an air cushion device interconnecting the beam assembly with the frame. The pivot coupling at the front wheel torque box with the frame and the beam assemblages interconnecting the frame with the rear wheel sets constitute a three point suspension for the frame. A progression steering mechanism is provided including an eliptical sprocket and chain arrangement which intercouples the rear wheel set with the steering for the front wheel set via a drive shaft operably extending therebetween.
