Air brake assembly for a wheeled vehicle

An air brake assembly for a wheeled vehicle, comprising:

• a frame configured for supporting a driver and a plurality of mechanical devices, wherein the frame is defined as having a front portion, a rear portion, a vertical cross plane, a right portion, a left portion, and a vertical center plane, wherein the front portion is opposite the rear portion and is generally divided by the vertical cross plane, and wherein the right portion is opposite the left portion and is generally divided by the vertical center plane;
• a first rigid substrate defining a first end opposite a second end;
• a second rigid substrate defining a first end opposite a second end;
• wherein the first and the second rigid substrates are pivotably connected to one another at their respective seconds ends at a first joint;
• a first support defining a first end opposite a second end;
• a second support defining a first end opposite a second end;
• wherein the first and the second supports are pivotably connected at their respective second ends to the frame at a second joint;
• wherein the first end of the first support is pivotably connected to the first rigid substrate between the first and the second ends of the first rigid substrate at a third joint;
• wherein the first end of the second support is pivotably connected to the second rigid substrate between the first and the second ends of the second rigid substrate at a fourth joint;
• an actuator connected to the frame configured to move the first joint forwards and backwards relative to the front and rear portions;
• wherein the first and the second rigid substrates are configured to be generally adjacent to one another in a closed position for minimal air braking affect when the wheeled vehicle is in a forward motion;
• and
• wherein the first and the second rigid substrates are configured to be generally at an acute angle to one another in an open position for an increased air braking affect greater than the minimal air braking affect when the wheeled vehicle is in the forward motion.
