近年来,助动车风靡上海滩,而其所造成的大气污染严重地影响到人民的身心健康。于是,禁声日盛。助动车的流行有其一定的客观因素,在现时上海人上下班路途较远而公交线路设计还不够完善的情况下,助动车也不失为一种简捷灵便的交通工具。那么,如何消除助动车严重的废气和噪声污染呢?采用零排放的电动车来取代汽油车是行之有效的方法。电动助动车即在助动车上安装高效蓄电池,再由电动机驱动运动构件,以此辅助人力踏车。欧洲、北美在八十年代后期发展的电动助动车速度一般可达20—40km/h,由于采用
In recent years, mopeds have swept the beach, and the air pollution they cause has a serious impact on the people’s physical and mental health. So, prosperous prosperous. The prevalence of mopeds has its own objective factors. At present, people in Shanghai commute to work far away from the bus line design is not perfect, the moped can be a simple and convenient means of transport. So, how to eliminate the severe gas and noise pollution of the auxiliary car? The use of zero-emission electric cars to replace the gasoline car is an effective method. Electric vehicle that is installed in the auxiliary car efficient battery, then the motor-driven movement of moving components, in order to assist the human treadmill. In Europe, North America in the late eighties the development of electric vehicle speed generally up to 20-40km / h, due to the use of
