Loading method and loading device of loads of monorail framework and axle

Abstract

The invention discloses a loading device of loads of a monorail framework and an axle. The loading device comprises a framework and an axle connected to the framework; a base is installed at the middle of the framework; a traveling wheel tool is installed at one end of the axle facing to the interior of the framework, and a motor substitute tool is installed at one end of the axle facing to the exterior of the framework; the traveling wheel tool and the motor substitute tool are respectively connected with a force actuator for applying a three-way linear load; and the traveling wheel tool is also connected with a torque actuator for applying a torque. The base is used for mounting and retaining the position degree of freedom of the framework; the framework and the axle are assembled according to an actual connection relationship, and the force transmission therebetween is in line with the actual situation; and the three-way linear load and / or the torque is applied to the traveling wheel tool and the motor substitute tool through the force actuator and the torque actuator so as to be transmitted to the axle and the framework. The invention further discloses a load method of loads ofthe monorail framework and the axle by using the loading device of the loads of the monorail framework and the axle.

Description

technical field [0001] The invention relates to the field of vehicle bench tests, in particular to a loading device for the load of a monorail frame and an axle. The present invention also relates to a method for loading a monorail frame and an axle using the above-mentioned loading device for a monorail frame and an axle. Background technique [0002] As a part of rail vehicles, straddle-type monorail vehicles are gradually applied to the backbone lines of small and medium-sized cities, the encrypted lines of large and medium-sized cities, business districts, tourist areas and other lines at home and abroad. The bogie (including the frame) is the running part of the straddle-type monorail vehicle, and the structural strength of the bogie is related to the operation safety and service life of the whole vehicle. The structure of a straddle monorail vehicle is different from that of a traditional rail vehicle. Torque and linear loads usually act directly on the frame, and the...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no special test device for the straddle-type monorail bogie frame, and it is difficult to load the frame with torque and linear load at the same time, and the accuracy of loading cannot be guaranteed; there is no current method that can be referred to for the application of torque and linear load
