Abstract

A suspension structure for heavy equipment, comprising two opposite suspension beams, each of the two ends of the suspension beams is provided with lug plates, and each of the suspension lug plates is provided with several Hanging ear holes, the opposite sides of the two hanging beams are provided with several connecting plates, each of the connecting plates is provided with connecting holes, and each of the connecting plates is provided with several connecting plates connected to the corresponding hanging beams of stiffeners. In the present invention, each connecting plate runs through the hanging beam, disperses the contact force between the connecting plate and the hanging beam, enhances the range of the connecting plate’s bearing capacity, and the reinforcing ribs protect, support and avoid deformation of the connecting plate, and immediately The plate connects the lug surface and the welding surface to avoid angle changes between the lug surface and the welding surface.

Description

technical field [0001] The invention relates to a suspension structure for heavy equipment, which belongs to the field of rail vehicle body design. Background technique [0002] At present, there are some shortcomings in the suspension beam of the underframe equipment of urban rail transit vehicles: when the suspension equipment is heavy, the beam rigidity is insufficient and the vibration amplitude is large; when the train impacts, cracks are prone to appear in the stress concentration area, and the risk of fracture increases. Starting from the above risk points, the present invention makes full use of the structural characteristics of the hanging beams, and effectively avoids the occurrence of risks through ingenious design. Contents of the invention [0003] In order to solve the above existing problems, the present invention discloses a hanging structure for heavy equipment, and its specific technical scheme is as follows: [0004] A suspension structure for heavy equ...
