Full torque crank assemblies

A crank assembly, comprising:

• a connecting rod;
• a first gear;
• a second gear;
• a follower gear;
• a follower gear connector;
• a geared rotational guide;
• and
• a crank journal;
• wherein said connecting rod has a piston end that is configured to be connected to and driven by a piston;
• wherein said connecting rod has a gear end and wherein said gear end of said connecting rod is substantially oblong in shape;
• wherein said oblong gear end of said connecting rod comprises a first geared interior surface and a geared exterior surface;
• wherein said first geared interior surface of said oblong gear end of said connecting rod is configured to matingly engage with said first gear;
• wherein said first geared interior surface of said oblong gear end of said connecting rod has a long side length and a short side length;
• wherein said short side length is greater than a diameter of said first gear;
• wherein said geared exterior surface of said oblong gear end of said connecting rod is configured to matingly engage with said follower gear;
• wherein said crank journal is rotateably received by said first gear, such that said first gear is freely rotatable around said crank journal;
• wherein said follower gear and said crank journal are connected via said follower gear connector, such that said follower gear and said first gear are on opposite sides of said oblong gear end of said connecting rod, and such that said first gear is in moveable but continuous contact with said first geared interior surface of said oblong gear end of said connecting rod while said follower gear is in moveable but continuous contact with said geared exterior surface of said oblong gear end of said connecting rod;
• wherein said first gear is connected to said second gear, such that when said first gear rotates said second gear also rotates;
• wherein said second gear is configured to matingly engage with and rotationally move within a second geared interior surface of said geared rotational guide;
• wherein said geared rotational guide is substantially circular;
• wherein said second gear's motion along said second geared interior surface of said geared rotational guide causes said crank journal to move in a substantially circular path;
• wherein said piston linearly drives said connecting rod, which in turn moves and rotates said first gear, which moves said second gear within said geared rotational guide;
• and
• wherein said crank journal is connected to a crankshaft, and wherein said crankshaft is rotated when said crank journal moves in a substantially circular motion.

A crank assembly, comprising:

• a connecting rod;
• a first gear;
• a second gear;
• a countershaft;
• a third gear;
• and
• a fourth gear;
• wherein said connecting rod has a gear end and wherein said gear end of said connecting rod is substantially oblong in shape;
• wherein said oblong gear end of said connecting rod comprises a geared interior surface;
• wherein said geared interior surface of said oblong gear end of said connecting rod is configured to matingly engage with said first gear;
• wherein said geared interior surface of said oblong gear end of said connecting rod has a long side length and a short side length;
• wherein said short side length is greater than a diameter of said first gear;
• wherein said first gear is connected to said second gear, such that when said first gear is rotated said second gear is also rotated;
• wherein said second gear is solidly connected to said third gear such that when said second gear rotates said third gear rotates in the same direction;
• wherein said third gear is matingly connected to said fourth gear, such that when said third gear is rotated said fourth gear is rotated in an opposite direction;
• and
• wherein said fourth gear is configured to matingly engage with said driveshaft.
