  • Patent number: 10082201
    Abstract: The invention relates to a vehicle powertrain that includes an internal combustion engine, a transmission driving at least two wheels, and an intermediate unit connecting the engine and a transmission housing enclosing the transmission. The intermediate unit is configured to allow relative rotation between the engine and the transmission housing about an axis (X) that is colinear with an engine output shaft and a transmission input shaft. The arrangement prevents engine vibrations from being transmitted to the transmission, and prevents torque shock from the vehicle wheels from being transmitted to the engine.

  • Patent number: 7792626
    Abstract: A method for operating an engine arrangement with a first internal combustion engine and a second internal combustion engine in a vehicle is provided. The method may include partially coupling a first crankshaft of the first internal combustion engine in the vehicle with a second crankshaft of the second internal combustion engine in the vehicle to start the second internal combustion engine, where the first crankshaft and second crankshaft are partially coupled with a clutch. The method may further include decoupling the first and second crankshaft when the second engine is operating under its own power. The method may further include coupling the first crankshaft and the second crankshaft, where the first and second crankshafts are coupled with the clutch when a speed difference between the first and second crankshafts is below a predetermined value and a relative angular position between the first and second crankshafts is less than 360°.

  • Patent number: 7753019
    Abstract: The invention relates to a transmission assembly (34), for imparting a phase difference between an outer wheel and an inner wheel of a spline VVT. The assembly comprises a tubular meshing member (36) having an inner surface (38) and an outer surface (40), wherein at least a portion of the inner surface is provided with a first spline (42) and at least a portion of the outer surface is provided with a second spline (44). The first spline and the second spline do not have the same pitch in the same groove direction. The transmission assembly further comprises a bearing arrangement (46) and an actuation member (48). The bearing arrangement is arranged between the meshing member and the actuation member to allow a transfer of an axial displacement of the actuation member to the meshing member and allow a rotation of the meshing member relative to the actuation member.

  • Patent number: 7212896
    Abstract: A vehicle control system (10) including a vehicle motion control subsystem (12) that has an input receiving an intended driving demand (14) and a plurality of coordinator subsystems (16) for coordinating actuators of the vehicle. The vehicle motion control subsystem (12) communicates with the coordinator subsystems (16) to determine whether a single coordinator subsystem (16) can carry out the intended driving demand (14). The vehicle motion control subsystem (12) will distribute demand signals among one or more of the coordinator subsystems (16) to allow the vehicle to implement the intended driving demand (14).

  • Patent number: 6705560
    Abstract: A method is provided for switching reels in a paper machine that includes applying an adhesive onto a continuously running paper web to begin a new paper roll and severing the continuous paper web from the tail end of the newly completed roll. The running paper web is supported by a reel drum and wound onto exchangeable reel shafts in contact with the reel drum in order to form rolls of paper. A hopper with a heater heats an adhesive agent to temporarily lower its viscosity and stickiness for smooth and even applying. A pair of nozzles, mounted on a pair of rodless cylinders and translating therewith, spray jets containing said adhesive onto the web and/or the reel shaft. The web is then advanced onto the reel shaft thereby forming an adhesive interface between the web and the shaft. Tension is applied across the adhesive interface to sever the paper web at the adhesive interface, thereby separating the trailing end of the paper web of the previously completed roll from the current paper roll.

  • Patent number: 6119447
    Abstract: The invention relates to an arrangement for determining the oxygen buffer capacity in a catalytic converter (1) of an exhaust system. The arrangement includes an oxygen sensor (3, 32, 33) located downstream of at least one converter matrix (30, 31), where the sensor (3, 32, 33) supplies an input signal to a fuel injection control unit (4). The arrangement includes an analyzer circuit (13) for determining time information (TP) about the fluctuation of said input signal (25, 26), and calculating means for calculating the oxygen buffer capacity based on said time information (TP) when the downstream sensor is used to provide a primary control input signal (26). The invention also relates to a method of determining the buffer capacity.

  • Patent number: 6079116
    Abstract: A through-air drying apparatus for drying a traveling wet paper web supported on a continuous fabric comprises a dryer roll about which the fabric and web are partially wrapped and which has a foraminous roll face, a supply hood which surrounds the portion of the roll about which the fabric and web are wrapped and which supplies heated air through the fabric and web and through the roll face into the interior of the roll, and an exhaust system for exhausting air from the roll. An axial exhaust passage is formed through at least one head of the roll. An exhaust manifold is connected to the exhaust passage and defines two outlets on opposite sides of the manifold. A pair of movable ducts are sealingly and releasably engaged with the outlets in the opposite sides of the manifold, the ducts being spaced apart on opposite sides of the roll so that an access space is defined between the two ducts for access to the roll and supply hood.
