Flywheel energy storing device and transportation vehicle adopting same

Abstract

The invention discloses a flywheel energy storing device and a transportation vehicle adopting the same. The flywheel energy storing device comprises a flywheel and a detachable transmission device; the flywheel is used for storing kinetic energy; the detachable transmission device is used for connecting the flywheel with the outside in case of need, and therefore the effect that energy storing of the flywheel is accelerated when an outside power device runs, and power is output outwards through the flywheel when the outside power device does not run is achieved. According to the flywheel energy storing device and the transportation vehicle adopting the same, when a traffic jam occurs, an engine is stopped, and the flywheel energy storing device is adopted to drive an automobile to drive, so that energy waste and engine wear which are caused by repeated starting of the engine and in-situ idling and exhaust gas emission beyond standards are avoided.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction of automobiles, in particular to a flywheel accumulator and a vehicle using the same. Background technique [0002] In the central areas of large and medium-sized cities, the traffic is often congested, especially during rush hour; if you encounter traffic lights, you will wait for a long time. At this time, the car often drives slowly or idles on the spot. brake status. This state not only causes waste of energy, but also causes severe pollution of vehicle exhaust at this time, exceeding the emission standard, which is also an important source of air pollution in large and medium-sized cities. With the continuous increase of the total number of vehicles, this problem has attracted more and more attention. [0003] To solve the problem of urban air pollution, replacing fuel vehicles with electric vehicles is the main solution currently proposed. However, electric veh...

Problems solved by technology

However, electric vehicles are not only expensive, but also have problems such as battery quality. At present, they can only be sold with policy subsidies. After they are sold, there are few charging piles, and people encounter the problem of long charging time and difficult charging.

According to a survey report released by relevant departments, in the short term (at least ten years), fuel vehicles still account for more than 90% of the total number of vehicles, and it will not be easy to replace fuel vehicles with electric vehicles for a long time
