AIR/OXYGEN BRAKE FOR VEHICLES

A braking system may include an enclosed cylinder and a double-sided piston assembly disposed therein. The double-sided piston assembly includes a first piston disposed within the enclosed cylinder, a second piston disposed within the enclosed cylinder, and a linear piston leg connecting the first piston and the second piston. The linear piston leg includes two opposite racks. A segmented pinion is disposed between the two opposite racks, where the segmented pinion includes a cogged segment and a cogless segment. The cogged segment and the cogless segment are on opposite sides of the segmented pinion. A brake shaft is connected to and rotatable with the segmented pinion. A transmission system is configured to couple the brake shaft to a drive shaft of a vehicle. Compressed air or oxygen may be drawn in or discharged from the enclosed cylinder via a one-way inlet valve and a one-way outlet valve.
