  • Patent number: 11453980
    Abstract: A turnout includes a fixed beam, and a first and a second movable beams respectively on two opposite sides of the fixed beam. The fixed beam is arranged on a turnout platform. The first movable beam is movably arranged on the turnout platform between a first and a second positions. The second movable beam is movably arranged on the turnout platform between a third and a fourth positions. When the first movable beam is at the first position, the second movable beam is at the third position, the first movable beam is separated from the fixed beam, and the second movable beam and the fixed beam form a first passage; when the first movable beam is at the second position, the second movable beam is at the fourth position, the second movable beam is separated from the fixed beam, and the first movable beam and the fixed beam form a second passage.

  • Patent number: 8650979
    Abstract: A drive system of an electric vehicle includes a drive motor, a transmission and a hydraulic system. The transmission has an input shaft, a countershaft, an output shaft, a first transmission unit placed between the countershaft and the output shaft, a first clutch, a second transmission unit placed between the countershaft and the input shaft, and a second clutch. The drive motor is attached to the input shaft, which is attached to the countershaft to provide power of the drive motor to the countershaft; the first clutch is configured for linking or cutting off the power transmission between the countershaft and the first transmission unit; and the second clutch is configured for linking or cutting off the power transmission between the countershaft and the second transmission unit. The first transmission unit has a first transmission ratio greater than a second transmission ratio of the second transmission unit.

  • Patent number: 8337351
    Abstract: A hybrid power driving system includes a planetary gear mechanism having a first rotating component, a second rotating component, and a third rotating component. The system also includes an electric motor operatively coupled to the first rotating component, a clutch, an internal-combustion engine operatively coupled to the first rotating component by the clutch, and a brake operatively coupled to the second rotating component and configured to control the second rotating component in a locked position or in an unlocked position. The third rotating component is operatively coupled to an output end to provide rotational power.

  • Patent number: 8336653
    Abstract: A hybrid power drive system includes an engine, a first motor, a first clutch operatively coupled between the engine and the first motor, a first decelerating mechanism having an input portion operatively coupled between the first clutch and the first motor, where the input portion is configured to receive rotational power from the first motor and/or the engine. The first decelerating mechanism has an output portion operative to drive at least one first wheel, and a second motor is operatively coupled to at least one second wheel through a second decelerating mechanism. An energy storage device is coupled separately to the first motor and to the second motor. The engine, the first clutch and the first motor are connected in sequence, and the second decelerating mechanism and the at least one second wheel are connected in sequence. Various combinations of operating modes are provided to meet energy efficiency requirements and user power demands.

  • Patent number: 8307925
    Abstract: The present invention provides a hybrid power driving system comprising: a first subsystem designed to input/output power; a second subsystem designed to input/output power; a driving shaft designed to receive power from the first subsystem and/or the second subsystem or output power to the first subsystem and/or the second subsystem; and a tri-stated overrunning clutch designed to connect the first subsystem and the second subsystem, wherein the tri-stated overrunning clutch may be in an overrun state, an engaged state, or a disengaged state. The first subsystem and the second subsystem can comprise an engine, a motor, and a clutch, etc., respectively. In such a hybrid power driving system, when the tri-stated overrunning clutch is in the engaged state, the first subsystem and the second subsystem are coupled to each other and work together.
