    摘要: An archery bow with a cam surface in fixed and force transmitting relation to each opposing limb and a torsion device extending between the cam surfaces, a cam following device on each end of the torsion means in force transmitting relation to the cam surfaces on the opposing limbs. A torsion rod and torsion tube and combinations of these may be used to both multiply the draw force transmitted to the arrow and to provide synchronization of the opposing bow limbs.
