Steering assembly having an adjustable alignment arrangement

A steering alignment arrangement having an adjustable suspension height for supporting a vehicle tire comprising:

• a steering spindle defining a steering spindle bore;
• a mounting bracket for supporting said steering spindle;
• a tire axle extending outwardly from said steering spindle for supporting a vehicle tire thereon;
• a kingpin extending through said steering spindle bore and having a central axis;
• at least one joint positioned adjacent said steering spindle bore connecting said steering spindle to said mounting bracket;
• and
• at least one spacer removably positioned about said kingpin, between said steering spindle and said at least one joint wherein said spacer is selectively positioned adjacent at least one end of said steering spindle to selectively position said tire axle along the central axis of said kingpin to adjust the suspension height of the steering assembly.

A steering alignment arrangement having an adjustable caster for supporting a vehicle tire comprising:

• a steering spindle defining a steering spindle bore;
• a mounting bracket for supporting said steering spindle, said mounting bracket having an adjustable seat;
• a tire axle extending outwardly from said steering spindle for supporting a vehicle tire thereon;
• a kingpin extending through said steering spindle bore and having a central axis;
• at least one stem having a predetermined length extending substantially perpendicular to said mounting bracket and having a proximal end associated with said kingpin and a distal end supported by said mounting bracket adjustable seat wherein said mounting bracket adjustable seat receives said stem in a plurality of positions to adjust the caster of the vehicle tire by moving said kingpin wherein its central axis extends angularly with respect to a vehicle axis.

A vehicle steering assembly for supporting a vehicle tire comprising:

• a steering arrangement;
• and
• an alignment arrangement connected to said steering arrangement, said alignment arrangement comprising a steering spindle defining a steering spindle bore, a mounting bracket for supporting said steering spindle, said mounting bracket having an adjustable seat, a tire axle extending outwardly from said steering spindle for supporting a vehicle tire thereon, at least one joint positioned adjacent an end of said spindle bore, said joint defining a bore coaxially positioned with said steering spindle bore, a kingpin extending through said steering spindle bore and said bore of said at least one joint and having a central axis wherein said steering spindle is positioned along the central axis of said kingpin and has a suspension height wherein the suspension height is adjustable by vertically moving the steering spindle along the kingpin central axis, and at least one adjustable stem having a predetermined length having a proximal end associated with said at least one joint and a distal end associated with the mounting bracket adjustable seat wherein the length of said stem between said mounting bracket and at least one joint is adjustable to position the kingpin in a variant position relative to a vertical axis wherein the kingpin central axis extends angularly to the vertical axis in a first plane to alter the camber of the alignment arrangement and wherein said distal end of said at least one stem is movable in a substantially horizontal pivotal direction to adjust the caster of the alignment arrangement by altering the central axis of said kingpin wherein said kingpin central axis extends in a second plane, transverse to said first plane, at an angle with respect to the vertical axis.
