Description
Technical Field
The invention mainly relates to the field of urban traffic systems, in particular to a rubber-tyred articulated bogie for a trolley bus and the trolley bus.
Background
The modern urban traffic system is mainly composed of subways, tramways, buses and the like, and although the subways are strong in transportation capacity, the subways are huge in cost, so that the subway transportation system cannot be widely applied to medium and small cities; the tramcar needs a special power system and a rail to be designed in a matching way, so that the design and construction cost or the maintenance cost is relatively high, and the tramcar is easily limited by the operation environment; the traditional bus is limited by the transportation capacity and cannot meet the demand of the early and late transportation peak stage of the city; the embarrassing situation can be well relieved by the appearance of the automobile train. Motor trains are defined in ISO3833-1997(E) and GB3730.1-83 as "a combination of a motor vehicle (truck or tractor) and one or more trailers". The development of the automobile train in the middle and small cities replaces the traditional bus, and not only can the transportation capacity be improved, but also the transportation cost can be reduced by about 30 percent under the condition of ensuring the safety factors such as the trafficability and the steering performance of the automobile train.
However, the conventional articulated automobile train has disadvantages that the rear wheel cannot be steered, a large inner wheel difference (difference between the turning radius of the front inner wheel and the turning radius of the rear inner wheel when the vehicle turns, called inner wheel difference) is caused, the turning radius is large, and the trafficability is poor. When the track automatic following control adopting the multi-axle active steering technology is adopted, when the central axis of a controlled vehicle runs on the same track, the passing performance of the long-marshalling articulated automobile train can be greatly improved, the steering inner wheel difference is reduced, and the influence caused by the sight dead angle is reduced, so that the accident rate caused by the length-lengthening of the vehicle body is reduced, and the integral transportation capacity is improved on the premise of ensuring the integral passing performance and the steering performance of the vehicle. However, when the vehicle body is lengthened, for example, 30 meters or more, the traditional centralized power form is obviously no longer suitable, and when the distributed power is adopted, the power steering bridge with the power input port is not easy to realize low floor.
