Vehicle wheel support device

A vehicle wheel support device for supporting wheels of a vehicle that runs on a railroad track including two rails laid parallel to each other, comprising:

• a first support frame rotatably supporting a first wheel so that the first wheel can roll on one of the rails, the first support frame supporting a vehicle body of the vehicle through a suspension system;
• a second support frame rotatably supporting a second wheel facing the first wheel in a lateral direction orthogonal to a traveling direction of the vehicle so that the second wheel can roll on the other of the rails, the second support frame supporting the vehicle body through a suspension system;
• first to fourth L-shaped links each having a middle bending portion that is pivotally supported by the vehicle body;
• and
• first to fourth support links, one ends of which are respectively pivotally joined to upper ends of the first to fourth L-shaped links,
• wherein
• the first and third L-shaped links are disposed symmetrically in the lateral direction with respect to the second and fourth L-shaped links,
• the first and third L-shaped links are pivotally supported by a lower portion of the first support frame, and other ends of the first and third support links one ends of which are respectively joined to the upper ends of the first and third L-shaped links, are pivotally joined to an upper portion of the second support frame,
• the second and fourth L-shaped links are pivotally supported by a lower portion of the second support frame, and other ends of the second and fourth support links one ends of which are respectively joined to the upper ends of the second and fourth L-shaped links, are pivotally joined to an upper portion of the first support frame.
