A vibration dampening suspension device for isolating a truck cab from the force vibrations of a vehicle frame, which includes an impact plate mounted to the truck cab, and a support plate mounted to the vehicle suspension. The device further includes a link member pivotally interconnected at one end with the support plate at a support pivot, and a lever member with a first end pivotally interconnected with the impact plate at a main pivot. The link member is pivotally interconnected with the lever member for rotation of the lever member with respect to the main pivot during compression of the shock absorber when the supporting body, suspended body and device are in a dynamic condition. A hydraulic shock absorber is provided with a first end pivotally interconnected with the lever member second end at a shock pivot and the second end pivotally interconnected with the impact plate at a pivot spaced from the main pivot. An air spring interconnected between the impact and support plates, and a torque arm pivotally interconnected between the impact plate and support plate, are also included. |
