Embodiment 1

[0085] Embodiment 1: Hydraulic planetary gear train continuously variable transmission

[0086] Referring to accompanying drawing 6, the motor / generator and battery pack in accompanying drawing 1 are omitted, and the hydraulic accumulator 16 is reduced into a miniature hydraulic buffer with a capacity below 3L, and the variable pressure of it and the hydraulic motor The controller oil cylinder 23 is connected, and the system is a continuously variable transmission with a locking function. The hydraulic buffer mainly prevents the flow imbalance during the transition process, and provides pressure parameters to automatically control and adjust the respective displacements of the hydraulic pump and the hydraulic motor, so that the displacement of the hydraulic pump can be adjusted automatically, and the displacement of the hydraulic motor can be automatically adjusted. Suppose the rated torque of the hydraulic motor is N times that of the hydraulic pump.

[0087] For the aforeme...

Embodiment 2

[0096] Embodiment 2: Machine-hydraulic hybrid driving device

[0097] Referring to accompanying drawing 7, the motor / generator, converter and battery pack in accompanying drawing 1 are omitted, and the hydraulic accumulator and hydraulic air-conditioning compressor are retained, and the system is a mechanical-hydraulic hybrid drive with a continuously variable transmission device.

[0098] For the aforementioned family car, the parameters for configuring the device of the present invention are as follows: the transmission refers to Embodiment 1, the hydraulic accumulator is an airbag accumulator with a rated pressure of 25-31Mpa, and the nominal volume is based on the ratio of system braking energy recovery and the hydraulic accumulator. It is set according to the requirements of hybrid cycle drive, which requires a high proportion of brake energy recovery, a larger capacity of 30-50L when the cycle is long, and a maximum energy storage of about 600kj, which is equivalent to t...

Embodiment 3

[0103] Embodiment 3: Electromechanical hybrid driving device

[0104] Referring to accompanying drawing 8, the hydraulic accumulator in accompanying drawing 1 is omitted, and a synchronous or asynchronous electric motor / engine with a small size but a high rotating speed is installed on the power shaft of the engine, and its power is relatively higher than that of the mechanical-hydraulic-electric hybrid drive. Larger, more than 10kw / 1500rpm, when the car is running at low speed under urban road conditions, it is driven by electromechanical hybrid cycle. When the engine is working, the motor is a generator connected to the power shaft of the engine through a clutch, increasing the engine load, converting mechanical energy into electrical energy and storing it in the battery. When the battery pack is charged to the upper limit, the engine is stopped, the motor is switched to an electric motor, the clutch is disconnected from the engine and connected to the heart wheel of the pla...
