Abstract

The invention relates to the technical field of walking mechanisms for maglev vehicles, and particularly relates to a walking mechanism for middle / low-speed maglev vehicles. The walking mechanism for middle / low-speed maglev vehicles comprises at least two end part suspension frames and at least an intermediate suspension frame, each suspension frame comprises two longitudinal beams, sliding tables, air springs, a transverse draw bar and an anti-side-rolling draw bar, wherein the two longitudinal beams are arranged in a left and right mode, the sliding tables and the air springs are arranged in the middle of the longitudinal beams, each longitudinal beam is provided with a sliding table, the sliding table is fixedly supported on the longitudinal beam through the air spring, the sliding tables are connected through the transverse draw bar, the longitudinal beams are connected through the anti-side-rolling draw bar, the transverse draw bar and the anti-side-rolling draw bar are located in the middle of the suspension frame, the sliding tables of the intermediate suspension frame are provided with a linear guide rail extending along the transverse direction, the sliding tables of the intermediate suspension frame are connected with a train body through the linear guide rail, and the sliding tables and the longitudinal beams are connected through traction bars. The walking mechanism disclosed by the invention has the beneficial effects that as a method that the sliding tables are arranged in the middle of the suspension frames and a linear bearing replaces a swing bolster and a Z-shaped traction bar is adopted, the structure of the walking mechanism is simplified, and the walking mechanism is convenient to maintain.

Description

technical field

[0001] The invention relates to the technical field of a running mechanism of a magnetic levitation vehicle, in particular to a running mechanism of a medium-low speed magnetic levitation vehicle. Background technique

[0002] Medium and low-speed maglev trains are a new type of transportation for urban passenger rail transit. They have the advantages of low noise, strong acceleration and braking capabilities, strong climbing capabilities, small turning radius, low vibration, and good comfort. Usually, the carriages of medium and low-speed maglev trains use the same running mechanism. In order to ensure that the maglev vehicle can pass through the curved track smoothly and stably, the two ends of the carriage are connected with two fixed-point suspension frames, and the middle is connected with several mobile suspension frames.

[0003] The traditional fixed-point and mobile suspension frames have air springs and sliding tables at the four ends of the two lo...
