Embodiment 1

[0104] The bogies involved in the low-floor rubber-tyred bogies of smart rail cars based on wheel-side motors in the present invention are divided into two types: independent type and integral type according to the axle form. The difference is in the axle.

[0105] This embodiment takes the free-standing structure as an example, and describes it in detail in conjunction with the accompanying drawings.

[0106] figure 1 It is the front view of the independent rubber-tyred bogie in the low-floor rubber-tyred bogie of the intelligent rail car based on the wheel-side motor of the present invention. figure 2 It is a top view of the independent rubber-tyred bogie in the low-floor rubber-tyred bogie of the intelligent rail car based on the wheel-side motor of the present invention.

[0107] Such as figure 1 and figure 2 As shown, the present invention discloses a low-floor rubber-tyred bogie for smart rail cars based on wheel-side motors, which includes wheel-side motor assembl...

Embodiment 2

[0140] Different from Embodiment 1, this embodiment takes the integral structure as an example and describes it in detail with reference to the accompanying drawings.

[0141] image 3 It is the front view of the integral rubber-tyred bogie in the low-floor rubber-tyred bogie of smart rail tram based on the wheel-side motor of the present invention. Figure 4 It is a top view of the integral rubber-tyred bogie in the low-floor rubber-tyred bogie of the intelligent rail car based on the wheel-side motor of the present invention.

[0142] Such as image 3 and Figure 4 As shown, the present invention discloses a low-floor rubber-tyred bogie for smart rail cars based on wheel-side motors, which includes wheel-side motor assemblies 10, integral axles 70, rubber wheels 30, rims 40, steering mechanisms 50 and steering Frame frame 60. Wherein, the rubber wheel 30 is installed on the rim 40, and is fixed on the rim 40 by external tension after being inflated, for example. The rim...

Abstract

The invention provides an intelligent rail tramcar low-floor rubber wheel bogie based on a wheel side motor. The intelligent rail tramcar low-floor rubber wheel bogie comprises a wheel side motor assembly, an independent suspension axle, rubber wheels, rims, a steering mechanism and a bogie frame. The rubber wheel is mounted on the rim, and the rim is locked and fixed on the wheel-side motor assembly; steering knuckles on the wheel side motor assemblies are connected with an upper cross arm and a lower cross arm of the independent suspension axle; a steering knuckle arm of the steering mechanism is fixed on a steering knuckle in the wheel side motor assembly, and a steering rocker arm of the steering mechanism is mounted on the bogie frame through a rotating shaft; and an upper cross arm and a lower cross arm of the independent suspension axle are arranged on the bogie frame. All-wheel drive is realized by adopting a wheel-side motor technology, the problem of insufficient power of four or more knotted intelligent rail tramcars is solved, and the requirement of large traffic volume in intelligent rails is met; the independent suspension axle and the integral axle structure are adopted, passengers can get on and off conveniently, and the running stability of the intelligent rail tramcar is improved.

Description

technical field [0001] The invention relates to the field of smart rail cars, in particular to a low-floor rubber wheel bogie for smart rail cars based on wheel side motors. Background technique [0002] In the existing technology, the smart rail car is a new type of urban rail transit vehicle with multi-section marshalling, full-axis steering, medium and large capacity, and low floor. As a city operation, it is imperative to arrange low-floor transportation for passengers to get on and off. . Achieving medium and large volumes requires sufficient interior space, that is, a sufficient number of marshallings. At the same time, it is necessary to be equipped with sufficient power to achieve medium and large transportation volumes. The urban operating roads have a small curve radius, and vehicles are required to have full-axis steering functions. [0003] The existing platform of the smart rail tram is a three-section marshalling, six-axis full-steering, 12×4 drive form (powe...
