Multiple degree of freedom cab suspension system

A suspension system for controlling multiple degrees of freedom of a cab of a vehicle with a chassis structure, the suspension system comprising:

• front left, front right, rear left, and rear right mounting pads configured to support the cab;
• front left, front right, rear left, and rear right brackets, each of which is connected with a corresponding one of the mounting pads;
• a spring and damper assembly connected between the chassis structure and each one of the brackets, the spring and damper assemblies configured to allow the cab to move with multiple degrees of freedom;
• a front lateral rod connected with one of the front right bracket or the front left bracket, extending laterally across the cab, and connected with the chassis structure outboard from the other one of the front right bracket or the front left bracket, the front lateral rod configured to restrict a side-to-side motion of the cab;
• a longitudinal rod connected with one of the front left bracket or the front right bracket, extending past one of the rear spring and damper assemblies, and connected with the chassis structure rearward from the one of the spring and damper assemblies, the longitudinal rod configured to restrict a front-to-back motion of the cab;
• a stabilizer bar connected with the front right bracket, the rear right bracket, and the chassis structure, the stabilizer bar configured to maintain a prescribed forward and rearward pitch rate of the cab;
• and
• a roll control bar connected with the rear left bracket, the rear right bracket and the chassis structure, and configured to maintain a prescribed left and right roll rate of the cab.

• front left, front right, rear left, and rear right mounting pads configured to support the cab;
• front left, front right, rear left, and rear right brackets, each of which is connected with a corresponding one of the mounting pads;
• a spring over damper assembly connected between the chassis structure and each one of the brackets, the spring over damper assemblies configured to allow the cab to move with multiple degrees of freedom;
• a first structural member extending between, and connected with, the front left and front right brackets;
• a second structural member extending between, and connected with, the rear left and rear right brackets;
• a front lateral rod connected with the front right bracket, extending past the front left spring over damper assembly, and connected with the chassis structure outboard from the front left spring over damper assembly, the front lateral rod configured to restrict a side-to-side motion of the cab;
• a rear lateral rod connected with the rear right bracket, extending past the rear left spring over damper assembly, and connected with the chassis structure outboard from the rear left spring over damper assembly, the rear lateral rod configured to restrict the side-to-side motion of the cab;
• a left longitudinal rod connected with the front left bracket, extending past the rear left spring over damper assembly, and connected with the chassis structure rearward from the rear left spring over damper assembly, the left longitudinal rod configured to restrict a front-to-back motion of the cab;
• a right longitudinal rod connected with the front right bracket, extending past the rear right spring over damper assembly, and connected with the chassis structure rearward from the rear right spring over damper assembly, the right longitudinal rod configured to restrict the front-to-back motion of the cab;
• a stabilizer bar connected with the front right bracket, the rear right bracket, and the chassis structure, the stabilizer bar configured to maintain a prescribed forward and rearward pitch rate of the cab;
• and
• a roll control bar connected with the rear left bracket, the rear right bracket and the chassis structure, the roll control bar configured to maintain a prescribed left and right roll rate of the cab.
