The gearbox drives the auxiliary component and increases the rotational speed of the auxiliary component from the first speed to the second speed. The low power take-off shaft also drives another generator, in one example.

  • Publication number: 20100105511
    Abstract: A controlled differential, particularly for exercising steering control of skid steered vehicles, having a compound planetary gear set coupling two shafts. Respective ring gears turn with the shafts and mesh with a compound planet gear in a planet carrier, the ratios of the number of gear teeth between each ring gear and the respective gear of the compound planet being unequal so that when the planet carrier is stationary the two shafts are coupled through the differential to turn together in the same sense but with a speed difference, and controlled rotation of the planet carrier varies the speed difference between the shafts in accordance with the sense and speed of rotation of the planet carrier.

  • Patent number: 7627407
    Abstract: An ECU determines the presence/absence of a fault of a negative pressure generation device that has an ejector that generates a negative pressure that is greater than the negative pressure that is to be extracted from an intake manifold of an internal combustion engine, and a VSV that causes the ejector to function or stop functioning. The ECU includes a presence/absence-of-abnormality determination portion that determines the presence/absence of an abnormality of the negative pressure generation device on the basis of variation of the rotation speed Ne of the internal combustion engine in accordance with change in the state of operation of the VSV.

  • Patent number: 7537535
    Abstract: A device for conversion of a rotational movement into a movement of each of two working levers defining a truncated cone and a self-rotating movement of each of the two working levers and vice versa comprises a lever bearing element which is rotatable around a rotation axis. The two working levers are each self-rotatably positioned around a self-rotation axis in the lever bearing element. A planetary wheel is arranged in a non-rotatable manner on each working lever. The planetary wheels are each coupled to a sun wheel, which is able to be blocked from turning, via a transmission wheel, the sun wheel being arranged around the rotation axis. This device for conversion of movement is utilisable for a great variety of uses and has a simple mechanical construction.

  • Patent number: 7442141
    Abstract: In an exemplary embodiment, a transmission outputs power from two high-speed, high-powered motor/generators into two coaxial output shafts for left and right wheels of a vehicle. Embodiments of the invention provide for a transmission that is coaxially mounted with the output shafts and the two motor/generators, which allows for a space-saving design. The transmission provides at least two degrees of freedom such that torque to each of the left any right wheels of driveshaft can be separately controlled by controlling the input/output of each of the motor/generators. The transmission may include two differential units to allow a significant gear reduction such that motor/generators that require high output speeds may be used.

    Abstract: A motor vehicle transmission includes a power splitter connected with the vehicle engine and two differential clutches connected with the outputs of the splitter. Separate gearboxes including alternating sequential gear mechanisms are arranged in each gearbox. The clutches are independently operated under control of an electronic control unit to provide continuous flow of power from the engine to the gearboxes which may be simultaneously operated. The clutches are driven by motors, respectively, under control of the electronic control unit.

  • Patent number: 7351174
    Abstract: The twin turbo-shaft engine according to the invention comprises a high pressure rotor and a low pressure rotor, at least one accessory gearbox driven by mechanical transmission means, main drive pinion means, on each rotor, driving power transmission means each associated with an input to a differential, the output of which drives a drive shaft of the accessory gearbox. It is characterised by the fact that the power transmission means extend in two different structural arms, the power transmission means of one of the rotors being connected to a power transfer box fulfilling two functions, firstly transmission of power to an input to the differential, and secondly modification of the transmission speed. The required space in each arm is thus reduced and the efficiency of the accessory gearbox is high.

  • Patent number: 7163480
    Abstract: A hybrid-electric powertrain for a vehicle having forward traction wheels and rearward traction wheels in an all-wheel drive configuration. An engine and an electric motor deliver power through delivery paths to the traction wheels. The power delivery paths may have multiple ratio gearing so that more power can be delivered mechanically to improve powertrain performance and to allow the electric motor size to be reduced. The powertrain may include a controller for automatically balancing power distribution to the forward and rearward traction wheels to avoid wheel slip.
