Problems solved by technology

However, when the car body is lengthened, such as 30 meters long or longer, the traditional centralized power form is obviously no longer suitable. When decentralized power is adopted, the power steering axle with power input port is not easy to achieve low-floor

Embodiment 1

[0027] Embodiment 1: as figure 1 As shown, the rubber-tyred power frame for trackless guided trams of the present invention includes an active steering axle assembly 1, a power shaft assembly 2 with a biased power input port for dual-tire load or single-tire load, a drive motor 3 and two With hinge assembly 4, driving motor 3 is connected with final reducer and differential gear in the offset power input port, and angle sensor is installed at the upper joint point in hinge assembly 4 to measure the angle of hinge. Two hinge assemblies 4 are located at the two ends of the power frame, and are used to connect with two adjacent compartments of the trackless guided tram.

[0028] In this embodiment, an angle sensor is installed on the active steering axle assembly 1 on the bogie to detect the wheel deflection angle.

[0029] In this embodiment, all wheels are equipped with wheel speed sensors to detect the wheel speed.

Embodiment 2

[0030] Embodiment 2: as figure 2 As shown, the rubber-tyred power frame for trackless guided trams of the present invention includes an active steering axle assembly 1, a power axle assembly 2 that adopts twin-tire bearing or single-tire bearing, wheel edge / hub motor 6 and two hinged assemblies 4. The wheel side / hub motor 6 is connected with the power shaft assembly 2 and drives the power shaft assembly 2 . An angle sensor is installed at the upper joint point in the hinge assembly 4 to measure the angle of the hinge. Two hinge assemblies 4 are located at the two ends of the power frame, and are used to connect with two adjacent compartments of the trackless guided tram.

[0031] In this embodiment, an angle sensor is installed on the active steering axle assembly 1 on the bogie to detect the wheel deflection angle.

[0032] In this embodiment, all wheels are equipped with wheel speed sensors to detect the wheel speed.

[0033] The present invention further provides a trac...

Abstract

A rubber-tyred power frame for a trackless-guided tram and a trackless-guided tram according to the present invention, the rubber-tyred power frame includes an active steering axle assembly, a power shaft assembly adopting twin-tire bearing or single-tire bearing, and a hinge joint adopting double joints Assemblies, the two hinged assemblies are located at both ends of the power frame, and are used to connect with two adjacent compartments of the trackless guided tram. The trackless guided tram includes a head assembly, an expandable body assembly with more than one section, a tail assembly and a control system, and the above-mentioned rubber wheel power frame is arranged between the head assembly and the body assembly and between the body assembly and the tail assembly. The invention has the advantages of simple structure, convenient installation, convenient control and the like.

Description

technical field [0001] The invention mainly relates to the field of urban traffic systems, in particular to a rubber wheel power frame suitable for a trackless guided tram and a trackless guided tram. Background technique [0002] Modern urban transportation systems are mainly composed of subways, trams, buses, etc. Although the subway has a strong transportation capacity, its cost is huge, which prevents it from being widely used in small and medium-sized cities; Both design and construction costs and maintenance costs are relatively high, and are easily restricted by the operating environment; traditional buses are limited by their transportation capacity, and cannot meet the needs of urban transportation peaks in the morning and evening; the emergence of automobile trains can better alleviate this problem. An embarrassing situation. Car trains are defined in ISO3833-1997(E) and GB3730.1-83 as "a combination of a car (truck or tractor) and one or more trailers". Developi...
