Background technology:
The trolleybus prior art: trolleybus is applicating history last 100 years since earlier 1900s is born.Trolleybus directly utilizes driven by power, does not have explosive motor, not discharging waste gas, noise is little, pollute little, since being born, because of its plurality of advantages obtains using comparatively widely in various countries' urban ground traffic, occupied critical role, but also had the following disadvantages:
1, because trolleybus is connected power supply by the fixing rod pantagraph current collector of overhead type contact net and vehicle (be commonly called as plait, also claim current-collector, be made up of with trolley head trolley pole).
1) fixedly overhead type contact net must be set, as cobweb, it is bigger that difficulty is set, and landscape effect is not good, and maintenance is also bigger.
2) necessary fixed vehicle travel route and track, the flexibility of working line adjustment and combination is relatively poor.
2, because trolleybus and other motor vehicles mix row, and the trolleybus speed of a motor vehicle is lower, can not adapt to modern city traffic above-ground requirement, also aggravated blocking up of urban ground traffic simultaneously.
Because above-mentioned deficiency, in recent years along with the maximization in city, the growth of motor vehicle flow, the increase of road number of track-lines, the contradiction of trolleybus traffic and other traffic above-grounds is increasingly sharpened, the application of trolleybus more and more is restricted in the urban ground traffic, suffer stagnation of movement in succession in most countries and city, prospect is more and more dulller.But because the trolleybus traffic has driven by power, pollutes little, less energy consumption, cost is low, the advantage of environmental protection, people thirst for solving the contradiction of trolleybus and other traffic above-grounds always, make the cheap and good-quality superiority of trolleybus continue to play a role in urban traffic.
