    摘要: Methods and systems are provided for the design and manufacture of a crankshaft of a piston internal combustion engine. In one example, a crankshaft comprises a crankshaft throw, the crankshaft throw comprising a crankpin and crank webs. The crank webs are formed asymmetrically in a region of the crankpin with respect to a plane intersecting an axis of rotation of the crankshaft and a center axis of the crankpin, such that the breaking strength of the crankshaft throw is increased at a crankshaft angle of rotation which differs from the top dead center position of a piston to which the crankpin is coupled, and at which the piston exerts a maximum combustion-induced force on the crankpin.

    摘要: A folding bicycle has a main-frame with a bottom bracket, crank, pedals, and a seat post. A front is attached to the main-frame by a front hinge having an axis parallel to the crank axis, and has a mono-fork suspension. The front frame rotates about the front hinge to a folded position wherein the mono-fork is behind the front hinge axis. A rear swingarm suspension has a rear sprocket and is attached to the main-frame by a rear hinge that preferably is coincident with the crank axis. The swingarm is of a single-stay configuration and is rotatable about the rear hinge to a folded position wherein the rear sprocket is forward of the crank axis. The main-frame may consist of left and right sidewalls spaced apart from one another, and the mono-fork lies at least partially between the sidewalls when the front frame is in the folded position.
