Abstract
A structural member for use in a vehicle body and frame assembly includes an internal air tank for supplying pressurized air to an auxiliary device, such as an active suspension for the vehicle. The internal air tank may be generally cup-shaped, including a closed end portion, a plurality of side portions, and an outwardly extending flange portion that extends about an open end portion. The flange portion is secured to a first portion of the closed channel structural member to define an air-tight chamber. The chamber is adapted to selectively receive and store a quantity of a pressurized fluid therein, and further to selectively discharge such pressurized fluid to an auxiliary device. An opening can be formed through the structural member to facilitate fluid communication with the chamber. Alternately, the internal air tank may include a flexible bladder defining an air-tight chamber.
