Abstract
A vibration dampening assembly and a suspension system for use, for example, between a cab and a flame of a truck, has a link with a first end pivotably interconnected with a second plate at a first support pivot, a lever with a first end pivotably interconnected with the second end of the link at a link pivot, a shock absorber, the first end of which is pivotably interconnected with the lever second end at a shock pivot and the second end of which is pivotably interconnected to a first or the second plate at a second pivot support spaced from the first support pivot wherein the lever is pivotably interconnected with the first plate at a main pivot connection located intermediate the first and second ends thereof. In one embodiment, the shock absorber central axis and the lever longitudinal axis are parallel when the supporting body and the suspended body are in a static condition. In another embodiment, a third plate is interconnected the second plate at a first lever pivot and the first plate is pivotably interconnected with the second plate at a second lever pivot laterally spaced from the first pivot support, and the first lever pivot is intermediate the first support pivot and the second lever pivot. In another embodiment, a second lever is interconnected to the first plate at a first lever pivot, the second plate and the second lever are interconnected at a second lever pivot spaced laterally from the first lever pivot and the first lever pivot is intermediate the link pivot and the second lever pivot. In another embodiment, an air spring is mounted between two of the plates or between a plate and a lever which are pivotably connected together to cushion the movement of one of the plates toward the other of the plates and to form a suspension.
