Tandem axle trailer suspension system

A trailer suspension system comprising:

• a first spring including a first spring end and a second spring end;
• and
• a second spring including a third spring end and a fourth spring end,
• wherein:
• the second spring end of the first spring is positioned adjacent to the third spring end of the second spring, and the second and third spring ends are disposed between the first and fourth spring ends,
• the second spring end of the first spring is rotatable about a first rotational axis and the third spring end of the second spring is rotatable about a second rotational axis, and
• the first and second rotational axes are fixed relative to each other, and the first spring end of the first spring and the fourth spring end of the second spring are movable relative to the first and second rotational axes,
• the first end of the first spring is rotatable about a third rotational axis that is movable relative to the first rotational axis, and
• the fourth end of the second spring is rotatable about a fourth rotational axis that is movable relative to the second rotational axis.

A trailer suspension system comprising:

• a first spring including a first spring end and a second spring end;
• a second spring including a third spring end and a fourth spring end;
• a first slipper mount receiving the first spring end of the first spring;
• and
• a second slipper mount receiving the fourth spring end of the second spring,
• wherein:
• the second spring end of the first spring is positioned adjacent to the third spring end of the second spring, and the second and third spring ends are disposed between the first and fourth spring ends,
• the second spring end of the first spring is rotatable about a first rotational axis, wherein the second spring end includes a first eye-end connector, and wherein the first eye-end connector has a first aperture that is aligned with the first rotational axis,
• the third spring end of the second spring is rotatable about a second rotational axis, wherein the third spring end includes a second eye-end connector, and wherein the second eye-end connector has a second aperture that is aligned with the second rotational axis,
• each of the first and the second slipper mounts include a top wall and opposing sidewalls that extend from the top wall,
• a first mechanical fastener and a second mechanical fastener extend through each of the first and second slipper mounts,
• the first spring end of the first spring is positioned between the sidewalls of the first slipper mount and between the first and second mechanical fasteners of the first slipper mount and the fourth spring end of the second spring is positioned between the sidewalls of the second slipper mount and between the first and second mechanical fasteners of the second slipper mount,
• the first and second rotational axes are fixed relative to each other,
• the first spring end of the first spring and the fourth spring end of the second spring are movable relative to the first and second rotational axes,
• the first spring end is slidably movable relative to the first and second mechanical fasteners of the first slipper mount, and
• the fourth spring end is slidably movable relative to the first and second mechanical fasteners of the second slipper mount.
