Abstract

The invention discloses an equalizing device for air spring height valves of medium-low speed maglev vehicles. The device comprises a height valve, a mounting plate, a torsion bar, a mounting suspender, a displacement transmission rod, an adjusting rod and a connecting rod, wherein the height valve is connected with the displacement transmission rod through the adjusting rod; one end of the displacement transmission rod is connected with a right mounting plate, and the other end is connected with the torsion bar; the torsion bar is connected with a left mounting plate; one end of the mountingsuspender is connected with a maglev vehicle body, and the other end is connected with the torsion bar. Displacement of modules is transmitted to the height valve through the adjusting rod connected to the displacement transmission rod to form a four-point height control system; since the front height valve transmits balanced displacement of the two modules, the relative displacement condition between a suspension frame and the vehicle body can be more accurately reflected, so that decoupling of the suspension frame and the secondary system formed by air springs are prevented from forming mutual coupling, and the condition that the vehicle body cannot suspend normally caused by pressing modules of the vehicle body in a bend due to excessive inflation or deflation of the air secondary suspension system is also prevented.

Description

technical field [0001] The invention belongs to the technical field of shock absorption for medium and low speed maglev vehicles, and in particular relates to an equalizing device for an air spring height valve of a medium and low speed maglev vehicle. Background technique [0002] Maglev vehicles have many advantages such as fast acceleration, stable operation, low noise, and strong climbing ability. In recent years, they have been rapidly developed in my country. Due to the decoupling requirements of the operating speed, comfort and bogies of maglev trains, most of them adopt air suspension systems. To form the secondary suspension system, the secondary suspension system of the maglev vehicle connects the car body and the suspension running part, which greatly affects the operation safety and stability of the vehicle. The air circuit design of the air suspension system of the maglev train should not only consider the connection The usual functions of the car and bogie, vibra...
