Abstract

The invention relates to an electric train braking energy recovery hydraulic energy-saving emission-reducing device with an electric train and a train energy-saving emission-reducing hydraulic device combined. Through combination of motor main power and hydraulic hybrid power energy-saving emission-reducing devices, when a train is in a braking process or an idling state and a transmission shaft of the train is in inertia rotating, mechanical energy is converted into hydraulic energy and is stored in an energy accumulator. When the train is started, the energy accumulator is started, hydraulic oil works through a plunger oil motor, hydraulic energy is converted to mechanical energy, the rotating speed and the torque output by the oil motor drive a main driver of the train, so that the train is started to walk, at the time, an engine can be in a complete idling state, and a hydraulic power device is used as an auxiliary power source to start the train to walk. According to the electric train braking energy recovery hydraulic energy-saving emission-reducing device, the hydraulic hybrid power device and the railway traffic transportation electric train are combined, the braking energy recovery hydraulic energy-saving emission-reducing device is suitable for a high-load multi-carriage multi-motor novel electric train, the purpose of electric train energy conservation and emission reduction is achieved, and the device is also suitable for fuel oil internal combustion engine train.

Description

Technical field [0001] The invention relates to an electric train with an electric motor as the main power, and specifically relates to an electric train brake energy recovery hydraulic energy-saving emission reduction device that combines an electric train and a vehicle energy-saving and emission-reduction hydraulic device. The combination of devices to achieve the purpose of energy saving and emission reduction belongs to the field of railway transportation. Background technique [0002] With the progress of modernization, there are more and more electric trains for railway transportation, especially the increase of intercity trains, which makes the number of stops for electric trains increase. For example, there are up to 10 stops for intercity trains from Shanghai to Nanjing. The electric train decelerates, brakes slowly, stops at the station, and starts idling very frequently. In particular, the starting power causes a large increase in the power consumption of the electric ...
