Independent air suspension for off-road trailers

#The present invention relates to suspension systems and, more particularly, to an independent air suspension for use on off-road trailers.

#Trailer suspensions are usually leaf spring or torsion. Neither of these conventional suspension systems have the travel or the stability required to traverse off-road conditions.

#As can be seen, there is a need for a suspension system that may provide ample wheel travel and stability to keep the wheels of a trailer on the ground through rough and uneven terrain.

#FIG. 1 is a perspective view of a suspension system according to an embodiment of the present invention; and

#FIG. 2 is a side view of the suspension system of FIG. 1.

#The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

#Various inventive features are described below that can each be used independently of one another or in combination with other features.

#Broadly, an embodiment of the present invention provides a suspension system for use on off-road trailers. The suspension system may be an independent air suspension system that may provide ample wheel travel and stability to keep the wheels on the ground through rough and uneven terrain. Conventional suspension systems may lack adequate wheel travel, may bounce too much, or may not be soft enough. The suspension system of the present invention may use an air bag to normalize the suspension for varying weights of the trailer load, allowing proper suspension for both heavy and light loads.
