Problems solved by technology

Hitachi monorail vehicles belong to medium and large monorail vehicles. The bogie has a double-axle structure and is loaded by air springs. It has a strong bearing capacity but a high floor surface, which is not conducive to the stability of the vehicle, and is not conducive to the simple and streamlined shape of the vehicle.
Bombardier adopts a single-axle low-floor bogie, which has high stability of the whole vehicle, but the single-axle model (total axle load 28t) leads to low carrying capacity of the vehicle, and the transport capacity cannot meet the needs of domestic cities with high population density

Abstract

The invention relates to a low-floor-surface straddle type two-shaft one-rail bogie comprising a framework, two traction motors and two sets of travelling wheels. The framework is provided with a middle beam, two side beams and end beams located at the two ends. From the train operation direction, the framework is in an inverted-U shape to be arranged on rail beams in a straddle mode, the two sides of the middle of the formwork are provided with L-shaped cantilevers extending downwards, and secondary damping springs are mounted on the cantilevers. The two traction motors are arranged at the front end and the rear end of the formwork correspondingly, the two sets of travelling wheels are arranged on the front side and the rear side of the middle of the formwork correspondingly, the traction motors drive the travelling wheels on the corresponding sides to rotate through gear boxes correspondingly, and the two gear boxes are located on the same side of the formwork. According to the low-floor-surface straddle type two-shaft one-rail bogie comprising a framework, the two gear boxes are arranged on the same side of the formwork, and the other side of the bogie reserves a large space so that the floor surface of the position of a vehicle can be lower.

Description

technical field [0001] The invention relates to a new type of monorail bogie. Compared with the existing monorail vehicles, the monorail vehicle adopting the bogie has the advantages of low floor surface and strong bearing capacity, which can effectively improve the driving stability of the monorail vehicle and make the whole vehicle The appearance of the vehicle is more concise and smooth, and the boundary of the vehicle is improved, belonging to the technical field of rail vehicle bogies. Background technique [0002] Monorail transportation is a three-dimensional transportation tool that is not disturbed by other transportation vehicles and pedestrians on the ground. It also has the advantages of low cost, small footprint, short construction period, strong climbing ability, low noise, good vision, and adapting to complex terrain and geological requirements. , which is suitable for the medium traffic demand of small and medium-sized cities, and is very popular at home and ...
