Title:
POWER SWITCHING SYSTEM OF RACK RAIL VEHICLE, POWER SWITCHING METHOD AND RAILWAY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/155479
Kind Code:
A1
Abstract:
A power switching system of a rack rail vehicle, comprising a power switching device (5), and a rack rail driving gear (2), an axle driving gear (3) and a power gear (4) that are mounted on an axle (1) at intervals. The power switching device (5) comprises a first gear ring (51), a second gear ring (52) and an axial driving mechanism (53). An inner gear of the first gear ring (51) is engaged with an outer gear of the rack rail driving gear (2), and an inner gear of the second gear ring (52) is engaged with an outer gear of the axle driving gear (3). The power gear (4) is provided between the rack rail driving gear (2) and the axle driving gear (3), and two side surfaces of the power gear (4) can be engaged with opposite side surfaces of the first gear ring (51) and the second gear ring (52) by means of splines (9), respectively. The axial driving mechanism (53) can drive the first gear ring (51) and the second gear ring (52) to move in the axial direction at the same time, such that the power gear (4) is engaged with the first gear ring (51) or the second gear ring (52). The axial driving mechanism (53) can drive the first gear ring (51) and the second gear ring (52) to move at the same time, such that stable power switching of the rack rail vehicle is realized, and the structure is simpler and more reliable. Also disclosed are a method for switching power of the power switching system of the rack rail vehicle and a railway vehicle equipped with the power switching system of the rack rail vehicle.
