Embodiment 1

[0049] A straddle-type monorail system adapted to different slopes by adjusting the wheel-rail force according to the present invention, comprising:

[0050] The bogie is located on the beam body. The bogie includes traveling wheels 11, guide wheels 12 and stabilizing wheels 13. The guide wheels 12 are arranged above the stabilizing wheels 13. Between the guiding wheels 12 and the stabilizing wheels 13 hinged connection between

[0051] Beam body, the beam body includes a running surface, a guiding surface and a stable surface, when the slope of the running surface of the beam body is greater than or equal to 100‰, the stable surface of the beam body is set inwardly from top to bottom;

[0052] A pressure adjustment device is connected to the beam body, and the pressure adjustment device can increase or decrease the pressure of the stable wheel 13 relative to the stable surface so that the running wheel 11 can move relative to the running surface pressure increases or decreas...

Embodiment 2

[0062] like Figure 11 As shown in the present invention, a straddle-type monorail system that adapts to different slopes by adjusting the force of the wheel and rail, its structure is roughly the same as that of Embodiment 1, the difference is that the bogie is provided with grooves For example, two snap rings are provided on the articulated arm of the guide wheel 12, the two snap rings are socketed with a gap between them, and the gap forms the groove. A sleeve 43 is arranged between the pin 41 and the spring 42, and the sleeve 43 is arranged and connected to the groove, and the sleeve can slide along the groove to facilitate positioning of the pin 41. It is further ensured that the pin 41 can be smoothly inserted into the slot. The side wall of the end cap of the pin 41 has a rolling bearing 44, and the rolling bearing 44 is used to roll and connect the positioning groove, changing sliding friction into rolling friction, making the pin 41 more likely to slide along the pos...

Abstract

The invention discloses a straddle type monorail system adapting to different gradients by adjusting a wheeltrack acting force. The system comprises a bogie arranged on a beam body, the beam body, anda pressure adjusting device. The bogie comprises a walking wheel, a guide wheel and a stabilizing wheel, the guide wheel is arranged above the stabilizing wheel, and the guide wheel is hinged with the stabilizing wheel; when the gradient of the walking surface of the beam body is larger than or equal to 10%, the stable surface of the beam body is obliquely arranged inwards from top to bottom; andthe pressure adjusting device is connected to the beam body, and the pressure adjusting device can enable the pressure of the walking wheels relative to the walking surface to be increased or decreased. By adopting the system, a normal acting force between the wheel rails can be effectively increased under the condition that the self weight of the vehicle is not obviously increased so that a traction limit of a wheel shaft between the wheel rails is increased, a purpose of running in a large-slope region is achieved, and barrier-free switching running on a large slope and a small slope can beachieved.

Description

technical field [0001] The invention relates to the technical field of a straddle-type monorail transportation system, in particular to a straddle-type monorail system adapting to different slopes by adjusting the force of a wheel and a rail. Background technique [0002] As a low-to-medium volume rail transit system, straddle-type monorail is an excellent choice to solve traffic problems in microcirculation systems such as small and medium-sized urban areas, traffic nodes and hubs, and tourist attractions. At present, due to the limitation of the weight of the vehicle itself and the friction force of the wheel and rail, the maximum slope of the straddle monorail system generally does not exceed 100‰, which greatly limits the application of the straddle monorail system in areas with large slopes such as mountainous areas and tourist attractions. limit. [0003] For the construction of straddle monorail projects in areas with large slopes (slope greater than or equal to 100‰...
