A suspension system for a vehicle having at least one pair of forward and one pair of rearward wheels, including: a suspension arm ( 7-10 ) for each wheel providing at least partial location of the associated wheel, the suspension arm ( 7-8 ) of the forward wheel being pivotally mounted to a vehicle body at a pivot position ( 11, 15, 12, 16 ) rearward to an axle line of the forward wheel, the suspension arm ( 9-10 ) of the rearward wheel being pivotally mounted to the vehicle body at a pivot position ( 13, 17; 14, 18 ) forward to an axle line of the rearward wheel; at least one lever arm ( 19-22 ) moving in conjunction with and extending radially from the pivot position ( 11-18 ) of each suspension arm ( 7-10 ); wherein at each respective side of the vehicle, a ram assembly ( 23, 24 ) is located between the lever arms ( 19-22 ) of the forward and rearward wheel, the ram assembly ( 23, 24 ) including at least a first ( 25, 27 ) and second ( 26, 28 ) variable volume fluid chamber, each fluid chamber ( 25-28 ) being in fluid communication with a fluid chamber ( 25-28 ) of an opposing ram assembly ( 23, 24 ) provided on the opposing side of the vehicle, such that there is fluid flow between the chambers ( 25-28 ) of the ram assemblies ( 23, 24 ) during heave motion of the vehicle, there is little to no fluid flow between the chambers ( 25-28 ) of the ram assemblies ( 23, 24 ) during roll motions, and there is an at least substantially longitudinal motion of the ram assemblies ( 23, 24 ) with little to no flow of fluid between the chambers ( 25-28 ) or the ram assemblies ( 23, 24 ) during cross axle articulations motion of the wheels. |
