  • Patent number: 11331996
    Abstract: A transmission has an input shaft, an output shaft coaxial to the input shaft, an intermediate shaft, a differential gear, and only one electric machine for driving a hybrid vehicle. The rotational axes of the input shaft, the intermediate shaft, the differential gear, and a rotor of the electric machine are axially parallel. The differential gear includes torque-transmitting interfaces to drive shafts connected to driving wheels of the hybrid vehicle. Torque is transmitted between the output shaft and the differential gear via the intermediate shaft. The rotor is permanently connected, via a constant gear ratio, to either the input shaft or a further shaft of the transmission. The rotational axis of the intermediate shaft is arranged spatially below a connection line between the rotational axes of the input shaft and the differential gear, and the rotational axis of the rotor is arranged spatially above the connection line.

    Abstract: The present invention is related to a traction drive synchronous governor and a multi-axis drive gearbox with the same, and includes a governor chamber and a speed change gear chamber. The present invention uses the synchronous governor that is deposited in the governor chamber to transmit the power of engine to an output set of the gearbox. The governor has multiple wheel assemblies between an input element and an output element in a planetary arrangement. The wheel assemblies are pushed by the output element to axially move to abut the input element to provide a power transmitting effect. At the same time, the shaft of each drive set in the speed change gear chamber is arranged in parallel at unequally spaced intervals and are surrounded by the output shaft as a center, and this may increase the number of gears of the gearbox in a limited space.

  • Patent number: 9517763
    Abstract: A transmission control system for a hybrid-power driving system includes at least a gear shifting actuation module to control engagement of specific gearwheels and a clutch actuation module to control a clutch that couples an engine to the transmission. Gear shifts are required for each of the engine and the electric motor in the hybrid-power driving system. By selectively controlling the clutch and engagement of specific gearwheels, the transmission control system can start the engine when the vehicle is initially powered by the electric motor alone. Starting the internal combustion engine in this case switches the vehicle from a pure motor driving mode to a hybrid driving mode. Additionally, the transmission control system can start the engine when the vehicle is in a parked state, for example, to put the vehicle in a battery charging mode for the electric motor.

  • Patent number: 9085298
    Abstract: A power transmission control device, which is applied to a hybrid-vehicle provided with an internal combustion engine (E/G) and a motor (M/G) as power sources, includes a manual transmission and a friction clutch. When the shift position is in “neutral”, the friction clutch is in an engaged state, an accelerator opening is “0”, and a battery remaining amount SOC is less than a threshold TH, a charge condition is satisfied. When the charge condition is satisfied, charge of a battery by using an E/G torque is carried out. Specifically, the M/G is driven, by using the E/G torque, as an electrical power generator, and electric energy acquired by electric power generation by the M/G is used to charge the battery. As a result, for the HV-MT vehicle, by using the internal-combustion-engine torque, the battery for supplying the electric motor with the electric energy can be efficiently charged.
