Degrees of luge trucks

  1. Aug 9, 2011 #1
    First off, I apologize if I have posted this in the wrong thread.

    Now in order for you guys to understand the basics of a luge board, I'll give you a short rundown.

    Here is a skateboard (or luge) truck. It consist of the hanger and baseplate. The hanger is what the wheels are attached to and it rotate on a pivot axis. The pivot axis is determined by the baseplate, the piece that is attached to the board. When you lean on the sides of the board, the bushings (red pieces) compress and allow the hanger to turn. In this picture, the baseplate is 47 degrees.

    Now a luge board typically consists of 3 trucks, 2 in the front and one in the rear. The rear truck usually consists of a 35 degree baseplate (can vary due to rider preference) and the two front trucks usually consist of 55 degree baseplates (also can vary due to rider preference). I will distinguish the 3 different trucks with numbers. Truck 1 will be the very front truck, truck 2 will be the 2nd truck, and truck 3 will be the rear truck. The distance between truck 1 and 2 is, lets say, 9cm. The distance between truck 2 and truck 3 is 106cm. Here is a picture of a typical luge board.

    Now if you think about it, since all 3 trucks are turning, there is a slight problem by having the 2 front trucks the same degree. I guess you can say it doesn't allow for a "perfect" turn. I want to figure out what degree to make truck 1 to allow for that "perfect" turn. I am guessing it will be a degree slightly larger than 55 degrees. Let me know if there are any variables that you would like to know. Any help would be appreciated! Thanks in advance. Let me know if I left anything out or if you have any questions.
