Abstract

The invention relates to an articulated multiaxial drive and bidirectional driving electric bus, belonging to the technical field of electric bus structure. The articulated multiaxial and bidirectional driving electric bus is characterized in that a chassis frame is provided with two differential driving axles, two differential driving steering axles, a front cab and a back cab; wherein, the differential driving axles are arranged in the middle of a bus body; In the middle of the differential driving axles, a first differential motor and a second differential motor are respectively used for supplying a torque for wheels at both ends; the two axles are articulated by a bus passage turntable; the part of the bus body, where the two axles are articulated, is provided with passage soft connection matched with the bus passage turntable; the differential driving steering axles are respectively arranged at the front side and back side of the bus body. The articulated multiaxial and bidirectional driving electric bus of the invention has simple structure and convenient maintenance as well as realizes articulated connection, multiaxial drive and bidirectional driving. The adoption of the differential driving axles and differential driving steering axles reduces intermediate link, so the bus starts rapidly, which has low noise, flexible steering and saving power supply.

Description

1. Technical field

[0001] The invention relates to an articulated multi-axis drive bidirectional driving electric passenger car, which belongs to the technical field of electric passenger car structures. 2. Background technology

[0002] Most of the electric buses currently used are driven by ①single wheel; ②DC motor is driven by chain; ③DC motor is driven by transmission shaft, reducer, and half shaft; its structure is complex, noisy, and consumes electricity. Avoid overturning, which is a big safety hazard.

[0003] The articulated buses that exist in the market are all one-way driving, and there is only one drive axle in the middle of the compartment. Due to the long body of the bus, it is inconvenient to realize U-turn in crowded places in large and medium-sized cities. 3. Contents of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art, and to provide an articulated multi-axis drive two-way driving ...
