specific Embodiment

[0039] The supporting device 4 in the step (1) selects the secondary hourglass spring of the bogie.

[0040] As another specific embodiment of the present invention:

[0041] The supporting device in the step (1) selects the secondary steel spring of the bogie.

[0042] Both the secondary hourglass spring of the bogie and the secondary steel spring of the bogie have a certain shrinkage after being compressed, and after being compressed, gaps that need to be added in the present invention can appear, and then the padding can be completed.

[0043] The present invention enumerates two kinds of adjusting pads, and its structure and specific padding method are as follows:

[0044] 1. The adjusting gasket selected in the step (5) is a plug-in adjusting gasket. The plug-in adjusting gasket is provided with an insertion hole from the center to the edge. During the process of inserting the adjusting gasket, the insertion hole The quasi-combined support rod, when inserted into the ce...

Abstract

A method for adding cushions to a bogie of a low-floor tram, comprising the following steps: (1) A bogie support device is arranged between the bogie frame and the car body, the perforation of the bogie support device and the bogie frame The threaded holes are butted, and a bracket is provided in the end of the perforation close to the car body, and a combined support rod is provided in the bracket; (2) A screw is inserted from the bottom of the perforation; (3) A nut is threaded on the screw; (4 ) Use a wrench to tighten the nut toward the car body. During the nut tightening process, the bogie support device is squeezed and shrunk, and a gap appears between the bogie support device and the car body; (5) Insert the adjustment pad in the gap (6) Remove the screw. In the present invention, the padding method is simple and feasible, saves manpower and material resources, improves padding efficiency, does not need to disassemble the connection between the bogie and the vehicle, does not cause damage to parts, and ensures safe and reliable operation of the tram.

Description

technical field [0001] The invention relates to a method for padding a bogie of a low-floor tram when it is not in operation, and belongs to the technical field of padding between the bogie and a car body of a rail vehicle. Background technique [0002] During the operation of low-floor trams, normal and abnormal wheel wear requires reversing to ensure the safety and comfort of the tram. It is necessary to add pads between the bogie and the car body to ensure that the floor surface of the tram is within a constant range, so as to avoid inconvenience to passengers getting on and off. [0003] In the actual padding process, it is necessary to remove all the connections between the bogie and the vehicle, and then restore the connection between the bogie and the vehicle after starting the padding. The operation process is complicated, and it is easy to cause damage to the parts during the disassembly process. , and the padding efficiency is very low, wasting a lot of manpower a...
