Abstract
A vehicle hydraulic suspension system has front left (15), front right (16), rear left (18) and rear right (17) wheel ram. There is a mode decoupling device (100) with first (129), second (130), third (132) and fourth (131) balance chambers formed by a cylinder/piston rod assembly (124,125,126). The compression chamber (45) of the front left wheel ram (15) is in fluid communication with the first balance chamber (129), the compression chamber (46) of the front right wheel ram (16) is in fluid communication with the second balance chamber (130), the compression chamber (48) of the rear left wheel ram (18) is in fluid communication with the third balance chamber (132), and the compression chamber (47) of the rear right wheel ram (17) is in fluid communication with the fourth balance chamber (131). There are also front and rear resilient vehicle support means between vehicle body and the wheel assemblies.
