CONTROLLED TRUCK CAB SUSPENSION

摘要

A suspension system for use between a cab (12) and an associated truck frame (14), including a strut module having a strut (52, 54), an air spring and a control module (58). The control module (58) connected to a source of pressurized air, is integral with the strut (52, 54) and includes a height sensor (60) for sensing a distance between the cab (16) and truck frame (14). The integral control module selectively pressurizes the air spring in response to changes in that distance. Preferably, the strut (52, 54) is magnetorheological, McPherson strut and the air spring (100) encloses at least a portion of the strut (52, 54) to provide a compact assembly. The strut damping characteristics are aired by the control module to provide optimize rider characteristic. The strut module includes a three-point connection to the cab and frame to resist relative lateral movement between the cab (12) and frame (14).
