H-type suspension frame type running mechanism

Abstract

The invention relates to an H-type suspension frame type running mechanism, which comprises two suspension frame type running mechanism units. The suspension frame type running mechanism units are formed by a suspension type swing bolster structure and a vehicle body connection structure, wherein the suspension type swing bolster structures comprise a suspension arm, a flexible support component and a swing bolster, wheel-pair H-type suspension units are formed, and clearances of a front electromagnet array, a rear electromagnet array, a left electromagnet array and a right electromagnet array can be changed in a self-adaptive way along with dynamics of a curve; and the vehicle body connection structures comprise a central pin and an arc-shaped sliding side bearing. When a maglev vehicle runs across the curve, the front suspension frame unit and the rear suspension frame unit can rotate horizontally relative to the vehicle body along with changes of the curve size of the line, the clearance of the left electromagnet array and the right electromagnet array can be changed dynamically along with the ''gauge'' of the line, suspension electromagnets can be better fitted with the line along with ultra-high and gentle-slope curves of the line, and the vehicle can smooth run across the curves. Therefore, by adopting the mechanism, free swinging of the front running unit, the rear running unit and the vehicle body can be realized, self-adaptive adjustment of the suspension electromagnets to be fitted with the line can also be realized, requirements of complete decoupling kinematics of the suspension frame type running mechanism can be satisfied, and true complete decoupling can be achieved.

Description

technical field [0001] The invention relates to a running mechanism of a magnetic levitation vehicle or other track maglev equipment, and belongs to the technical field of magnetic levitation. Background technique [0002] At present, the research on energy-saving, environment-friendly and convenient urban maglev transportation technology is very popular at home and abroad. Among them, the medium and low-speed light single permanent maglev vehicle, which has the advantages of small size, light weight, flexible operation, economy and energy saving, and low overall cost, is a new type of urban transportation in the future. However, the current engineering technology still needs breakthroughs, especially the design of a completely decoupled suspension frame running mechanism with a simple structure and easy control is particularly critical. [0003] When the maglev vehicle passes the curve, the distance between the left and right electromagnet arrays and the front and rear lev...

Problems solved by technology

In order to make the vehicle pass smoothly, either the gauge on the curved line should be narrowed according to a certain rule, but this will cause other models to fail to run; or the walking mechanism needs to be improved to adapt to the curve
