Double-energy power range-increasing type trolley bus

Abstract

The invention discloses a double-energy power range-increasing type trolley bus, which comprises a pantograph type current collector, a trolley pole and a bus body, wherein a traction motor, a control unit and a vehicular energy storage device are arranged in the bus body; and the control unit is used for controlling the energy storage device to provide power sources for the traction motor under the condition of interruption of the power supply of the traction motor. When in overtaking road sections or road sections without trolley wire networks, the power sources are provided by the energy storage device of the trolley bus to meet requirements on range increasing, and zero pollution and zero emission are realized truly; and moreover, the trolley bus has the characteristics of flexibility and energy conservation. A trolley wire network is simply hung by erecting two contact wires on a double-arm beam; and in order to save space and reduce visual pollution, the trolley wire network is vertically arranged in parallel in a staggered manner, and the trolley pole, which is matched with the trolley wire network, of the trolley bus is in the form of a double-wire pantograph type current collector, and can ascend and descend freely. The arrangement characteristics of a power grid comprise that cables of the power grid are manually laid under the ground at an intersection; and the problems of messy power grids and visual pollution of traffic intersections are solved thoroughly.

Description

technical field [0001] The invention relates to a trolley bus, in particular to a trolley bus capable of continuous power-extended range operation. Background technique [0002] The trolleybus is an important means of transportation for the development of energy-saving and "green" transportation systems. The main advantage of the trolleybus is that the vehicle itself emits zero pollutants to the atmosphere, and its energy is mainly provided by the overhead catenary. From the perspective of power performance and maintenance costs, trolleybuses are also superior to vehicles of the same level. From the perspective of urban public transportation, many cities have set up bus lanes, which also provide convenient conditions for the vigorous development of trolleybuses. At present, the factors that hinder the development of traditional trolleybuses are: 1) Compared with ordinary cars, traditional trolleybuses are less flexible and maneuverable. They must travel under the overhead l...

AI Technical Summary

Problems solved by technology

At present, the factors hindering the development of traditional trolleybuses are: 1) Compared with ordinary cars, traditional trolleybuses are less flexible and maneuverable.

If there is a road blockage, you can't detour and drive away from the scene like other vehicles, you can only park nearby, adding obstacles to the road

2) Once the power supply system fails, the operation of the entire line will be suspended

However, this type of trolleybus involves conversion between different energy sources, and the system is complicated, especially it cannot truly realize environmental protection, pollution-free, "zero emission"

The driving force of the latter dual power supply comes from the power supply network. Once the power grid fails, it is impossible to rely on the battery to drive the tram for a long time.
