Suspensions for low floor vehicle

A suspension system for a vehicle comprising:

• a first wheel;
• a second wheel;
• a first stub axle providing support to said first wheel about a first rotational axis;
• a second stub axle providing support to said second wheel about a second rotational axis,
• a frame including a substantially flat portion having a top surface, said first wheel being located on a first side of said frame, said second wheel being located on a second side opposing said first side of said frame, said portion being disposed generally beneath the first and second rotational axes;
• a pivotal support arm pivotally supporting said first stub axle, said pivotal support arm being pivotally coupled to said frame below the top surface and being pivotal relative to said frame about a pivot axis, said support arm including a projection adapted and configured for a pivotal connection;
• and
• a dampener having two ends with one of the ends being pivotally coupled to said frame, the other end of said dampener being pivotally coupled to said projection;
• wherein the pivot axis is in-between said first stub axle and said other end of said dampener.

A suspension system for a vehicle, comprising:

• a first wheel;
• a second wheel;
• a first stub axle providing support to said first wheel about a first rotational axis, said first stub axle being coupled to a first wheel support, said first wheel support being pivotally coupled to the vehicle by spaced-apart first and second pivot attachments, said first and second pivot joints establishing a common pivot axis
• a second stub axle providing support to said second wheel about a second rotational axis;
• a frame including a substantially flat portion having a bottom surface, said first wheel being located on one side of the portion of said frame, said second wheel being located on an opposing side of the portion of said frame, the first and second rotational axes being above the bottom surface, said frame having a first structural member proximate to said first wheel and in front of said first wheel;
• a biasing member for biasing said first wheel support to a position;
• and
• a wheel housing attached to said frame, said wheel housing having an inboard wall and a top wall;
• wherein said biasing member, said first stub axle, and said first wheel support are located outboard of the inboard wall and lower than the top wall.
