    摘要: A piston crank mechanism has an upper link coupled to a piston by a piston pin, a lower link having a crankpin journal, wherein the crankpin journal is coupled to a crankpin of a crankshaft and is coupled to the upper link by an upper pin, and a control link is coupled to an eccentric cam of a control shaft that is supported by an engine block and coupled to a control pin boss by a control pin. The crankpin journal of the lower link is arranged and dimensioned relative to the upper pin such that a projection area defined by projecting the width of the upper pin along a direction line passing through a center of the piston pin and a center of the upper pin does not obscure an area defined by the crankpin during operation of the crankshaft as viewed in an axial direction of the crankpin.

    摘要: An opening (35a) on one end side of a pin-boss oil passage (35) opens to the inner circumferential surface of a pin boss part (14) of an upper link (3), while an opening (35b) on the other end side thereof opens to the outer circumferential surface of the pin boss part (14) of the upper link (3). A lower-link oil passage (36) has a one-end-side opening (36a) structured to open to a pin-boss-facing surface (33) of the lower link (2) facing the outer circumferential surface of the pin boss part (14) of the upper link (3) and its other-end-side opening (36b) structured to open to a crankpin bearing surface (37). The lower-link oil passage (36) is configured to point, at a prescribed crankangle, to a specified end edge of end edges of the other-end-side opening (35b) of the pin-boss oil passage (35), the specified end edge facing one end side of the upper link (3).

    摘要: Joining surfaces (2a, 2b) of a pair of conductive joining members (1a, 1b) to be joined to each other are caused to face each other, and while one of the joining members (1a, 1b) is slid relative to the other of the joining members (1a, 1b), a current is passed from one of the joining members (1a, 1b) to the other of the joining members (1a, 1b) so as to cause resistance heating. Abrasion, plastic flow, and material diffusion therefore occur in high surface-pressure sections of the joining surfaces (2a, 2b), and the joining surfaces (2a, 2b) are joined together while current concentration locations are varied from moment to moment.

    摘要: A multi-link piston crank mechanism includes a lower link (7) having one end side to which an input load F1 due to a combustion load is acted. The lower link includes a bifurcated one end side protruding piece portion (13) and a bifurcated other end side protruding piece portion (14) which are positioned on both sides of a crank pin bearing portion (12). The bifurcated one end side protruding piece portion sandwiches the other end of an upper link (8). The bifurcated other end side protruding piece portion sandwiches the other end of a control link 9. A thickness of a central portion (12a) of the crank pin bearing portion (12) in a crank shaft axis direction is larger at a portion positioned on the one end side of the lower link (7) than at a portion positioned on the other end side of lower link (7). A thickness of a control link other end portion (32) is larger than a thickness of an upper link other end portion (24).

    摘要: A lower link (13) is formed such that outer circumferential sides of both end portions of a crankpin through-hole (21) are stiffer than a center portion of the crankpin through-hole (21), i.e. a bifurcation portion of a bifurcated shape thereof. The both end portions of the crankpin through-hole (21) are formed such that inner circumferential surfaces (22a) of the both end portions are curved at a predetermined curvature in an axial direction of a crankshaft with no load input on the lower link (13). Moreover, the center portion of the crankpin through-hole (21) is formed such that an inner circumferential surface (22b) thereof is located inward of the inner circumferential surfaces (22a) of the both end portions and is straight in the axial direction of the crankshaft with no load input on the lower link (13).
