Several embodiments of suspension systems for vehicle wheels arranged in pairs and having paired shock absorbers. The shock absorbers are interrelated in such a way that they provide a first degree of damping during certain kinds of suspension loadings and a second, different rate of damping in response to inertial conditions on the vehicle. Various control systems are disclosed.

A vehicle having a body; at least a pair of wheels; first and second hydraulic shock absorbers, each associated with a respective one of said wheels for suspending said wheels from said body for relative movement therebetween; each of said shock absorbers comprising a first chamber adapted to be pressurized upon movement of the wheel relative to the body, a shock absorbing passage continuously communicating said first chamber to a second chamber and a shock absorber valve arrangement in said shock absorbing passage for damping the suspension movement of the respective wheels by continuously controlling the flow between said first chamber and said second chamber; each of said shock absorbers thereby being effective to damp the movement of the respective wheel relative to the body independently of the other shock absorber; conduit means interconnecting said first chambers of the respective shock absorbers at a point between said first chambers and each shock absorbing valve arrangement; and control valve means in said conduit means for controlling the flow therethrough without obstructing the flow through the respective shock absorbing passages in response to a vehicle condition other than hydraulic pressure and for controlling the flow between said first chambers independent of said shock absorber valve arrangement for selectively providing damping interaction between said first chambers of said shock absorbers.
