Mobility vehicle

A mobility scooter comprising:

• a frame;
• a drive wheel coupled to the frame and rotatable about a drive wheel axis;
• and
• a steering assembly, coupled to the frame, that includes:
• a steering stem having a stem axis, the steering stem rotatable about the stem axis in response to input from a steering input;
• a front inside wheel,
• a steering stop, and
• a tie rod, pivotably coupled to the steering stem at a first end and pivotably coupled to a steering arm at a second end, and configured to pivot in response to movement of the steering input and to engage the steering stop when the front inside wheel reaches a maximum outward turn angle to prevent said front inside wheel from being turned beyond the maximum outward turn angle,
• wherein the steering stop engages the tie rod a first distance from the first end of the tie rod a second distance from the second end of the tie rod, and
• wherein a ratio of the first distance to second distance is at least 1.75:1.

A mobility scooter comprising:

• a frame;
• a drive wheel coupled to the frame and rotatable about a drive wheel axis;
• and
• a steering assembly, coupled to the frame, that includes:
• a steering stem having a stem axis, the steering stem rotatable about the stem axis in response to input from a steering input;
• a front inside wheel pivotable relative to the frame about a kingpin,
• a steering stop, and
• a tie rod, pivotably coupled to the steering stem at a first end and pivotably coupled to a steering arm at a second end, and configured to pivot in response to movement of the steering input and to engage the steering stop when the front inside wheel reaches a maximum outward turn angle to prevent said front inside wheel from being turned beyond the maximum outward turn angle,
• wherein an axis of the tie rod and an axis extending from the second end of the tie rod through the kingpin forms an angle Y, and
• wherein the angle Y is less than 22 degrees.

A mobility scooter comprising:

• a frame;
• a drive wheel coupled to the frame and rotatable about a drive wheel axis;
• and
• a steering assembly, coupled to the frame, that includes:
• a steering stem having a stem axis, the steering stem rotatable about the stem axis in response to input from a steering input;
• a steering position sensor configured to detect a position of the steering stem when the steering stem is rotated a first angle about the stem axis;
• a controller configured to process a signal from the steering sensor;
• a front inside wheel pivotable relative to the frame about a kingpin;
• a steering stop, and
• a tie rod, pivotably coupled to the steering stem and configured to pivot in response to movement of the steering stem and to engage the steering stop when the steering stem is rotated a second angle about the stem axis to prevent said front inside wheel from being turned beyond a maximum outward turn angle,
• wherein the second angle is between 5-25 degrees greater than the first angle.
