Document Type and Number:
WIPO Patent Application WO/2020/098433
Kind Code:
A1
Abstract:
A suspension structure of a tram, comprising: a frame (100); a front axle structure (200); a rear axle structure (300); a front suspension assembly (400), comprising two supports (410) which are symmetrically distributed on the left and right, the front axle structure (200) being simultaneously connected to the two supports (410), front thrust rod structures (420) being connected between the supports (410) and the frame, the front thrust rod structures (420) being also connected between the front axle structure (200) and the frame, and front airbag assemblies (430) being mounted on the supports (410); and a rear suspension assembly (500), comprising a pair of beam structures (510) which are symmetrically distributed on the left and right. The rear axle structure (300) is connected to the middle parts of the two beam structures (510) respectively; the middle part of each beam structure (510) is also connected to the frame by means of a rear thrust rod structure (520); rear airbag assemblies (530) are mounted at the two end parts of the beam structures (510) respectively; both the rear airbag assemblies (530) and the front airbag assemblies (30) are arranged as air spring structures; a rear vibration absorber structure (540) is connected to the side part of each rear airbag assembly (530); the rear vibration absorber structures (540) are connected to the frame; and a rear stabilizer bar structure (550) is also connected between the two beam structures (510). The suspension structure of the tram has the advantages of good vibration absorbing effect and good stability.
