Mounting bracket assembly and supplemental suspension system

1. A supplemental suspension system for use on an associated vehicle including associated sprung and unsprung masses and an associated primary suspension system operatively connected between the associated sprung and unsprung masses, the associated primary suspension system including an associated non-fluid spring and an associated jounce tongue supported along one of the associated sprung mass and the associated unsprung mass adjacent the associated non-fluid spring, said supplemental suspension system comprising:

an air spring assembly including a first end member operatively connected on one of the associated sprung mass and the associated unsprung mass, a second end member spaced from said first end member and disposed toward the other of the associated sprung mass and the associated unsprung mass, and a flexible wall secured therebetween and at least partially defining a spring chamber; and,

a mounting bracket assembly supported on the associated jounce tongue and spaced from the other of the associated sprung mass and the associated unsprung mass, said mounting bracket assembly including a top wall and an end wall, said top wall receiving said second end member of said air spring assembly, and said end wall including an opening dimensioned to receive the associated jounce tongue and support said mounting bracket assembly thereon.

2. The supplemental suspension system of claim 1 , wherein the associated sprung mass includes an associated vehicle frame, and said supplemental suspension system further comprises a frame bracket supported on the associated vehicle frame and including a bottom wall receiving said first end member of said air spring assembly.

3. The supplemental suspension system of claim 1 , wherein said mounting bracket assembly includes a first mounting bracket and a second mounting bracket operatively engaging said first mounting bracket, said first mounting bracket including said end wall and said opening for receiving the associated jounce tongue, and said second mounting bracket including said top wall receiving said second end member of said air spring assembly.

4. The supplemental suspension system of claim 3 , wherein said second bracket includes spaced side walls extending from said top wall and a rear wall extending between said side walls in approximately transverse relation to said top wall.

5. The supplemental suspension system of claim 4 , wherein said rear wall includes opposing extended wall portions extending outwardly beyond said side walls, and said supplemental suspension system further comprises a clamping member engaging said extended wall portions and operatively connecting at least said second bracket along the associated primary suspension system.

6. The supplemental suspension system of claim 1 further comprising a pressurized fluid source in communication with said air spring assembly and a controller operative to selectively energize said pressurized fluid source.

7. A supplemental suspension system kit for use on an associated vehicle including associated sprung and unsprung masses and an associated primary suspension system operatively connected between the associated sprung and unsprung masses, the associated primary suspension system including an associated non-fluid spring and an associated jounce tongue supported along one of the associated sprung mass and the associated unsprung mass adjacent the associated non-fluid spring, said kit comprising:

an air spring assembly including a first end member capable of being operatively connected on one of the associated sprung mass and the associated unsprung mass, a second end member spaced from said first end member toward the other of the associated sprung mass and the associated unsprung mass, and a flexible wall secured therebetween and at least partially defining a spring chamber;

a first bracket including a top wall and a rear wall, said top wall capable of receiving said second end member of said air spring assembly; and,

a second bracket capable of being connected to said first bracket and including an end wall, said end wall including an opening capable of receiving the associated jounce tongue and of being supported on the associated jounce tongue in spaced relation to the other of the associated sprung mass and the associated unsprung mass.

8. A supplemental suspension system kit according to claim 7 further comprising a frame bracket including an upper mounting portion capable of securement on the associated sprung mass and a bottom wall spaced from said upper mounting portion and capable of engaging said first end member of said air spring assembly.

9. A supplemental suspension system kit according to claim 8 further comprising a bail clamp capable of operatively connecting the associated non-fluid spring and said first bracket.
