Abstract: In a method for producing, from a cast or forged blank, a connecting rod intended for a reciprocating-piston engine and having one little and one big connecting-rod eye, the big connecting-rod eye is split, in a pre-machining step, along a parting plane running through the axis of the eye, the place side faces of the blank being ground beforehand in a first clamping station. After the plane faces of the blank have been ground, first the contour of the big connecting-rod eye and then the split in the parting plane are produced by laser cutting while the blank is held in a second clamping station.

Abstract: The present connecting rod assembly has a configuration of a substantially parallel sided elongate member, and a pair of rod bolts positioned for fastening the cap to the elongate member disposed at a splayed angle with the longitudinal axis so as to decrease side-to-side movement of the connecting rod cap. The invention further includes electrochemically processing the aluminum alloy connecting rod components in order to form an aluminum oxide matrix on the surface, and sealing the interstitial cavities of the matrix with an inert fluoropolymer to thus provide a composite layer providing added surface hardness and lubricity in order to decrease seizing and deformation of the connecting rod during use.

Abstract: A piston crank mechanism of an internal combustion engine includes an upper link connected to a piston, a lower link connected to both the upper link and a crankpin, and a control link through which the lower link is linked to an eccentric cam of a control shaft to restrict the degree of freedom of the lower link. By varying the angular position of the eccentric cam with respect to the control-shaft axis, the center of oscillating motion of the control link varies, thus varying a compression ratio. The center of gravity of the lower link, determined by an equivalent inertia weight obtained by adding weights of connecting pins and weights of the upper-link boss-shaped end and the control-link boss-shaped end connected to the lower link via the respective connecting pins to the lower-link self-weight, is situated closer to the center of the crankpin.

Abstract: A crank rod used in converting reciprocal movement into rotation, more particularly to an eccentric crank rod for overcoming problems due to failure in conversion of a linearly applied force into a rotation output force at the highest position and the lowest position on a vertical line when the rod is used in converting reciprocal movement into rotation as in a connecting rod of an internal combustion engine or an external combustion engine, or as in a geared crank rod of a bicycle. The crank rod is formed by a biased ex tension (3), a main length portion (5) and an intermediate transition (4) unitarily connecting the biased extension (3) to the main length portion (5). A force-applying portion (6) is formed at an off-centered position nearby an end of the main length portion (5) Both the force-applying portion (6) and the end of the main length portion (5) usually stop at a position across a vertical line L through the center of a crank pin. Both a biased extension (3) and an intermediate transition (4) of the crank rod according to the present invention are formed to have an obtuse internal angle so that an end of the crank rod usually stops after passing over a vertical line regardless of either a weight or a force applied to the force-applying portion (6).

Abstract: A connecting rod of a crank mechanism is made as a single sheet metal part by shaping without chip removal out of sheet metal. The connecting rod comprises a base sheet (1) that is provided with an upper connecting rod eye (2) and a lower connecting rod eye (3). Each of the connecting rod eyes (2, 3) has an integral cylindrical stamping (6, 7). The connecting rod further comprises a stiffening collar (8) that is integrally formed out of the base sheet (1) and is configured without interruption on the periphery of the base sheet (1).
