Structure of a motor-car type pure electric BRT road train

Abstract

A motor-car type pure electric BRT road train structure, which is composed of a guiding locomotive (1) and one or more pairs of power carriages (2), each pair of power carriages (2) is composed of two sections of single carriages; The guiding headstock (1) has a double-bridge structure, and each pair of power carriages (2) has two axles, which are respectively arranged in the middle of the two sections of single carriages. The front axle (4) of the guiding headstock is a steering The rear axle (5) is a drive axle, and at least one of the two axles of each pair of power carriages (2) is a drive axle; between the guide head (1) and the pair of power carriages (2), two groups Adjacent pairs of power carriages (2) are connected by a single ordinary traction hinge (9), and the middle of each pair of power carriages (2) is connected by an upper hinge (10) and a lower hinge (11); the power carriages The paired structure forms a central symmetry and can travel in both directions. The length of the structure can be adjusted according to the needs of different transportation volumes, the circle width of the turning channel is greatly reduced, and the wheel tracks are consistent when turning.

Description

technical field [0001] The invention relates to the field of structural design of road trains and EMUs, and designs a pure electric road train structure. [0002] technical background [0003] In recent years, the problem of road traffic congestion has become increasingly serious, especially for densely populated cities in China, the traffic burden during peak travel periods is extremely high. The transportation efficiency of the urban public transport system is reduced, which greatly increases the cost of the time people spend on the road. [0004] In order to alleviate the traffic pressure and improve the operating efficiency of buses, in recent years, my country has begun to implement the BRT rapid transit system in many cities. By opening up bus-only roads, the trackless operation of the similar rail transit mode can be realized. Its large carrying capacity and high operating speed can effectively relieve traffic pressure. [0005] The type of public transport vehicle t...

AI Technical Summary

Problems solved by technology

The biggest feature of the articulated bus is that the length of the body is longer. The biggest disadvantage brought by the long body is that the width of the channel circle required for turning is increased, and the occupied road area is larger.

Moreover, due to the long length of the vehicle, the steering wheel angle is too large, which increases the difficulty of the driver's operation to a certain extent.
