Driving gauge-changing device and method of gauge-changeable bogie

Abstract

The invention discloses a driving gauge-changing device and method of a gauge-changeable bogie. The driving gauge-changing device is composed of a sliding block assembly, an upper shaft box shell, a lower shaft box shell, a first shaft box end cover, a second shaft box end cover, a third shaft box end cover, a bearing boot, a lock head, a locking mechanism cover, a diaphragm type pressure sensor,a pull wire type displacement sensor, a lock head in-position switch, a data processing module, a controller, a first transverse hydraulic cylinder, a second transverse hydraulic cylinder and a vertical hydraulic cylinder. The controller controls the expansion and contraction of each hydraulic cylinder according to the digital signals of the diaphragm type pressure sensor, the pull wire type displacement sensor and the lock head in-position switch from the data processing module so that the gauge-changeable bogie can automatically complete the unlocking and locking of wheels and the transformation actions of the wheels under different gauge.

Description

technical field [0001] The invention relates to the technical field of bogie systems, more specifically, it relates to an active track changing device and method for a variable gauge bogie. Background technique [0002] Because countries in the world adopt different railway gauge systems, for example, China's railways are standard gauges with a gauge of 1435mm, and the railways of Russia and most countries in Eastern Europe and Central Asia are wide gauges with a gauge of 1520mm. There are also some national railways The gauge standard is narrow gauge 1000mm. Therefore, if railway vehicles want to run straight-through on standard gauge lines and wide and narrow gauge lines, they need to use variable gauge bogies; variable gauge bogies are an unconventional steering system. The main difference between it and the conventional bogie is the wheel set structure. The design of the wheel set structure is the key to realize the gauge change function. Compared with the conventional b...

Problems solved by technology

[0004] In order to solve the problem that the variable-gauge bogie cannot automatically adjust the gauge, and realize the automatic function of the variable-gauge bogie in the process of adjusting the inner distance of the wheel set as much as possible, the present invention provides an automatic track-gauge bogie. The track-changing device and method can realize the unlocking and locking of the track-changing wheel set and the adjustment of gauge automatically when the track-gauge bogie changes from wide gauge to narrow gauge or from narrow gauge to wide gauge
