Embodiment Construction

[0049] The detailed features and advantages of the present invention are described in detail below in the specific embodiments, the content of which is sufficient to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly, and according to the specification, claims and drawings disclosed in this specification , those skilled in the art can easily understand the related objects and advantages of the present invention.

[0050] The smart rail car is a new type of urban rail transit with multi-section marshalling, all-axis steering, and medium-to-large capacity. As a city operation, it is imperative to arrange a low-floor layout for the convenience of getting on and off passengers. In addition, enough interior space is required to achieve medium and large transportation volumes, that is, a sufficient number of marshallings is required; at the same time, sufficient power must be equipped to achieve medium and la...

Abstract

The invention provides a low-floor rubber wheel bogie based on a hub motor. The low-floor rubber wheel bogie comprises a hub motor assembly, an independent air suspension system, a rubber wheel, a rim, a disconnected steer-by-wire mechanism and a bogie underframe. The rubber wheel is installed on the rim, the rubber wheel and the assembly body of the rim form a rubber wheel assembly, and the rubber wheel assembly is fixedly connected with the hub motor assembly; the hub motor assembly is in spherical hinge connection with the independent air suspension system; the disconnected steer-by-wire mechanism is fixedly connected with the hub motor assembly, and the disconnected steer-by-wire mechanism is connected with the bogie underframe through a rotating shaft; the independent air suspension system is connected with the bogie underframe through rubber balls.

Description

technical field [0001] The invention relates to bogie technology, in particular to a low-floor rubber-tyred bogie based on a hub motor. Background technique [0002] The smart rail car is a new type of urban rail transit with multi-section marshalling, all-axis steering, and medium-to-large capacity. As a city operation, it is imperative to arrange a low-floor layout for the convenience of getting on and off passengers. In addition, enough interior space is required to achieve medium and large transportation volumes, that is, a sufficient number of marshallings is required; at the same time, sufficient power must be equipped to achieve medium and large transportation volumes; urban operating roads have small curve radius, and vehicles are required to have all axles. steering function. [0003] The existing platform of the smart rail car is a three-section marshalling, six-axis full-steering, 12×4 drive form (power is arranged at both ends), and the low floor is not fully pe...
