Novel gauge-changeable bogie track-changing function and reliability test bed

Abstract

The invention discloses a novel gauge-changeable bogie track-changing function and reliability test bed. The gauge-changeable bogie track-changing function and reliability test bed mainly comprises a mobile platform power driving device, a translation type gauge conversion device, bearing walking rails, a limiting device and a gantry type suspension device. The mobile platform power driving device drives the translation type gauge conversion device to move longitudinally through a motor-crank connecting link kinematic pair, the translation type gauge conversion device is used for unlocking and locking a gauge-changeable wheel set and provides a transverse guidance effect on the axial gauge-changeable motion of the gauge-changeable wheel set in the axial direction of the wheel set, the bearing walking rails provide bearing and vertical guide effects for the translation type gauge conversion device, the limiting device performs transverse centering positioning and vertical limiting for the motion direction, and the gantry type suspension device fixes the position of the wheel set of the bogie and unloads the wheel set. According to the invention, the cyclic track-changing action of the gauge-changeable wheel set is simulated through the reciprocating motion of the mobile platform, and a foundation is provided for researching the track-changing function and reliability analysis of the gauge-changeable bogie.

Description

technical field [0001] The invention relates to the field of dynamic simulation and testing of rail vehicles, in particular to a new track-changing function and reliability test bench of a variable-gauge bogie. Background technique [0002] Due to political, economic, technical and historical reasons, there have been different gauge systems for railway transportation for a long time. With the rapid development of global economic integration, trade and cultural exchanges between countries have become increasingly frequent, and railway transportation has gradually become One of the most important land trade channels for cross-border and cross-regional combined transport, and the difference in gauge has brought many restrictions to the development of international combined transport, so the variable gauge bogie that realizes the direct operation of different gauge intervals came into being. [0003] In order to make the gauge changing bogie after production can successfully com...
