摘要：
A vehicle suspension assembly includes an axle member movable between a first position and a second position, mounting brackets adapted to couple to a vehicle frame assembly, trailing arms pivotably coupled to mounting brackets and pivotably coupled to the axle member, a lift arrangement including a pair of diaphragm chambers each having a push plate and a flexible bladder, the push plate of the diaphragm chamber dividing the associated diaphragm chamber into a first compartment and a second compartment, the first compartment of each diaphragm chamber being adjustably pressurized to move the push plate of the associated diaphragm chamber, and at least one push rod defining a single longitudinal axis and connected to each push plate such that pressurization of the diaphragm chambers cause a translational movement of the at least one push rod, thereby causing the axle member to move between the first and second positions.
