Document Type and Number:
WIPO Patent Application WO/2022/083251
Kind Code:
A1
Abstract:
A central suspension device (6), a bogie (200), and a suspended rail transit system. The suspended rail transit system comprises a rail beam (a), a vehicle frame (100) and bogies (200), the vehicle frame (100) being connected to the rail beam (a) by means of the plurality of bogies (200), and each bogie (200) comprising a framework (4), a swing bolster (5) and a central suspension device (6), wherein the framework (4) comprises an upper chord beam (41), a lower chord beam (43) and connecting beams (42), the upper chord beam (41) and the lower chord beam (43) are arranged opposite each other, and the upper chord beam (41) and the lower chord beam (43) are connected by means of the plurality of connecting beams (42) arranged at intervals; and the swing bolster (5) is suspended in the middle of the lower chord beam (43) by means of the central suspension device (6), and the swing bolster (5) is arranged below the vehicle frame (100), and can be driven by the the bogies (200) to drive the vehicle frame (100) to travel below the rail beam (a). In the system, the structural sizes of the rail beam (a) and a pier column (b) which supports the rail beam (a) can be reduced, so as to reduce the steel consumption and achieve the aim of reducing the line construction cost.
