Abstract

The invention relates to a side-rolling-resisting torsion bar device and belongs to the technical field of rail vehicle equipment. The side-rolling-resisting torsion bar device has the advantages thata metal substrate is added into a rubber liner in each support seat, so that the shape of the rubber material can be kept, part of longitudinal deformation, generated by bending moment, on a torsionbar shaft is resisted, and uniform structural strain distribution is achieved; support ball hinges play an elastic support role, the torsional rigidity of the support ball hinges are controlled to bewithin 5% of the rigidity of the torsion bar shaft, the support seats are formed through casting, and hollowing-out weight reduction and reinforcing-rib reinforcement are performed on the support seats; large-curvature spherical-surface joint structural design is adopted, deflection and torsional rigidity are lowered, and deflection and torsion adaptability of the device is increased; two-layer structural design is adopted, the total thickness of the rubber layers can be increased under the situation that radial rigidity is kept unchanged, various-direction strain of rubber is lowered, structure durability is increased greatly, and the deflection and torsional rigidity is further lowered by the multilayer structure.

Description

technical field

[0001] The invention relates to an anti-rolling torsion bar device, which belongs to the technical field of rail vehicle equipment. Background technique

[0002] Existing medium and low-speed maglev trains (with a speed level of about 120km / h) are supported by electromagnetic attraction to make them non-contact with the track, and are driven by linear motors to realize train operation.

[0003] The suspension of medium and low-speed maglev trains is realized by the suspension modules arranged on both sides of the running mechanism. At the same time, traction devices are arranged on the modules to push the train forward. The lateral connection of the left and right modules is realized by anti-roll beams. The existing anti-roll beam is a parallelogram structure composed of plate girders, and the connection of two sets of plate girders is a flexible structural member. Although this solution can well realize the lateral decoupling of the left and right suspensio...
