On the one hand, when the maglev train passes through the moderation curve, due to the change of the transverse slope angle, the tracks corresponding to the four suspension points of the suspension frame are not coplanar, and the front-back anti-rolling decoupling mechanism is required to deform for adaptation, so that the decoupling of the left suspension module and the right suspension module is realized; the larger the change of the transverse slope angle is, the larger the deformation amount of the anti-rolling decoupling mechanism is required. On the other hand, when the maglev train falls, the anti-rolling decoupling mechanism needs to restrict the side rolling quantity of the left and right suspension modules, so as to avoid the collision of the traction linear motor with the track and realize the anti-rolling of the left and right suspension modules; the smaller the deformation amount of the anti-rolling decoupling mechanism is, the smaller the roll amount of the left and right suspension modules is. The suspension frame with the structural form has the rolling resistance and the decoupling performance which are mutually contradictory and mutually restricted. In the prior art, an anti-rolling decoupling mechanism is formed by adopting an elastic anti-rolling beam and a rigid suspender, and the rigidity of the anti-rolling beam is designed through compromise, so that the suspension frame has certain decoupling capacity and rolling resistance, which necessarily causes a certain rolling quantity when the suspension module falls down, and is not beneficial to the safe running of a vehicle.

Preferably, the length of the first boom 11 is longer than the length of the second boom 12 by a designed decoupling amount, wherein:
design decoupling magnitude > = moderation curve maximum lateral slope angle change rate x two anti-roll decoupling mechanism mounting distance x gauge.
It should be noted that, in the present invention, the installation arrangement of the first roll bar 9, the second roll bar 10, the first hanger bar 11 and the second hanger bar 12 is not limited to the above, and in another embodiment of the present invention, when the first roll bar 9 and the second roll bar 10 have the same right angle triangle structure, the large end of the first roll bar 9 is connected to the small end of the second roll bar 10 through the first hanger bar 11, and the small end of the first roll bar 9 is connected to the large end of the second roll bar 10 through the second hanger bar 12, and at this time, the length of the first hanger bar 11 is smaller than that of the second hanger bar 12.

The boom body 1 and the rubber joint 2 provided at both ends of the boom are preferably integrally formed, and the metal inner ring 211 and the boss 212 are preferably integrally formed, but the present invention is not limited thereto. Through the arrangement, the anti-rolling elastic suspender limited by the rubber node 2 has the functions of suspender expansion and suspender limitation, can ensure deformation and anti-rolling rigidity during anti-rolling, and has the advantages of simple structure and low cost.
