摘要： A crankshaft assembly for a motor vehicle drive train includes a crankshaft segment and a centrifugal pendulum secured to same, which has a carrier secured to the crankshaft segment and at least one pendulum mass that moves relative to the carrier along a predetermined track. The crankshaft assembly has a rupture containment means, which engages radially externally around the centrifugal pendulum such that components of the centrifugal pendulum coming lose during rotation of the centrifugal pendulum are collected by the rupture containment means.

摘要： A crankshaft for an internal combustion engine is provided. The crankshaft comprises at least four main journals aligned on a crankshaft axis of rotation defining a centerline. The crankshaft further comprises at least three pin journals. Each pin journal is disposed about a respective pin journal axis and positioned between the main journals. Each of the pin journals is joined to a pair of crank arms. Each pair of crank arms is joined to a respective main journal. Each of the main journals, pin journals, and crank arms is made of a first metallic material. Each crank arm has an over-molded counterweight metallurgically bonded thereto. Each counterweight is disposed opposite a respective pin journal relative to the centerline for balance and stability. Each counterweight is made of a second metallic material. The crankshaft has a weight ratio of the second metallic material to the first metallic material of between 0.20 to 0.50.

摘要： An annular cylinder liner includes an annular body defining a longitudinal axis, a radial direction perpendicular to the longitudinal axis, a circumferential direction, a first longitudinal end, a second longitudinal end, and a liner length measured from the first longitudinal end to the second longitudinal end along the longitudinal axis. The annular body also includes a shoulder that is disposed at the first longitudinal end, defining a shoulder axial thickness measured along the longitudinal axis. A ratio of the liner length to the shoulder axial thickness ranges from 24.0 to 46.0.

摘要： Provided is a fluid flow energy harvester (10) comprising a crankshaft (12) and at least one vane (14) pivoted into a sail portion (18) and a crank portion (20) on respective sides of the pivot (16). Both portions (18) and (20) are operatively oscillatable about the pivot (16) when the crank portion (20) is operatively arranged facing into a fluid flow (22). The crank portion (20) is linked to the crankshaft (12) via a crank (24) so that operative oscillation of the vane (14) imparts rotational force to said crankshaft (12). The harvester (10) also includes a fin arrangement (26) which comprises a fin (28) arranged on, and configured to guide, the sail portion (18) of the vane (14) facing towards or in a direction of the fluid flow (22). The harvester (10) also includes a fin actuator (30) configured to control an orientation of the fin (28) relative to the sail portion (18), so that during oscillation of the sail portion (18), either a surface (32) of the sail portion or a surface of the fin (34) impedes the fluid flow (22) when a surface of the other is parallel to such fluid flow. In this manner, stalling of the vane oscillation is counteracted thereby facilitating continuous rotation of the crankshaft (12) during fluid flow (22).

摘要： The present invention provides a rotary engine comprising: a housing provided with three lobe accommodation parts; a rotor which is provided with two lobes continuously accommodated in the lobe accommodation parts, has an intake storage part communicating with an intake port provided on the front surface-side, and has an exhaust storage part communicating with an exhaust port provided on the rear surface-side; an intake-side housing cover provided with an intake hole communicating with the intake storage part; an exhaust-side housing cover provided with an exhaust hole communicating with the exhaust storage part; and a crankshaft, wherein the flow of an exhaust gas into a stroke chamber during an intake stroke is reduced by preventing the exhaust storage part, at a portion of a section in which the exhaust port is open, from communicating with the exhaust hole during the intake stroke.

摘要： A method of assembling a crankshaft and a crank member comprises supplying a crankshaft including a crankpin which extends between crank arms, supplying two halves of a crank member, which are fixed to each other about the crankpin such that in assembled condition the crank member is rotatable about the crankpin and comprises a bearing portion having an outer circumferential wall for bearing a big end of a connecting rod and an external crank member gear for driving the crank member about the crankpin, wherein the halves are fitted about the crankpin, hence creating two contact faces at opposite sides of the crankpin, after which both halves are fixed to each other in circumferential direction by means of applying at least a fixation at a fixing place located remote from the bearing portion and the toothed surface of the crank member gear.

摘要： A piston engine crankshaft made from carbon composite molded in two separate moldings is disclosed. According to a preferred embodiment, the first mold takes the top dead center piston ignition load. The second molding takes the dynamic piston and rod load and contains the counterweight. Accordingly, carbon fiber filaments are aligned in preferred directions to optimally absorb loads at different areas of the crankshaft.

摘要： An electric bicycle is provided that can increase the diameter of the joining section between a crankshaft and a crank arm, suppress an increase in manufacturing cost, and minimize a size increase of a hanger with a torque sensor disposed in the hanger. A crankshaft 17 is divided into a crankshaft body 17A on the periphery of which a torque sensor 23 is disposed, and an auxiliary crankshaft 17B connected to one side of the crankshaft body 17A. A diameter D1 of the joining section between the auxiliary crankshaft 17B and a crank arm 18B and a diameter D3 of the joining section between the crankshaft body 17A and a crank arm 18A are larger than a diameter D2 of the connecting section between the crankshaft body 17A and the auxiliary crankshaft 17B.
