Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing:

[0034] Such as figure 1 As shown, it is the articulated structure of the present invention, the main components include spare shock absorber 3, rotating arm 8, hinged support 6, workshop shock absorber 2 and shock absorber 7; hinged support 6 is installed on two adjacent In the section car 1, on the left side of the bottom of the front compartment, the shock absorber 7 is installed on the right side of the bottom of the rear compartment; 9 is installed on the hinged support 6, so that the two ends of the rotating arm 8 can rotate horizontally around the vertical pin shaft 9; ; The front end of the shop shock absorber 2 is connected to the right end of the pivot arm 8, and the rear end of the shop shock absorber 2 is installed on the shock absorber seat 7.

[0035] Above-mentioned damping seat 7 and articulated support 6 and related components can be arranged in exchange o...

Abstract

The invention discloses a hinged shock absorption method and device for the active control compartment ends of an air rail train. The hinged shock absorption device comprises an inter-compartment shock absorber and a standby shock absorber which are arranged in a hinged structure, and the inter-compartment shock absorber is horizontally and obliquely arranged between two adjacent compartments andis the only connector for connecting the two adjacent compartments in the hinged structure. A first electromagnetic proportional overflow valve and a first pressure sensor are arranged on the inter-compartment shock absorber, and the first electromagnetic proportional overflow valve is controlled by a control system. The hinged shock absorption method and device have the advantages that no matterwhat working condition the train is under in the running process, the shock absorbers in the hinged structure can provide shock absorption damping parameters most suitable for the working condition, so that the compartments are always in the best mutual coordination state when encountering sharp increase of transverse and longitudinal acceleration amplitudes, and meanwhile, high-speed shock and shock excitation can be effectively inhibited; and when the inter-compartment shock absorber fails, the longitudinal shock absorber can take the shock absorption responsibility of the hinged structure in time.

Description

technical field [0001] The invention relates to a vehicle-end connection vibration-damping device, and specifically designs a hinged vibration-damping method and device for actively controlling the vehicle end of an empty rail train, belonging to the technical field of rail transit. Background technique [0002] Urban aerial rail trains (or suspended rail trains) are attracting more and more attention from some cities due to their advantages such as small land occupation, small investment, fast construction, flexible route selection, and indisputable ground road resources, and will become future cities. A very important part of the transportation system. [0003] The longitudinal and lateral control of the aerial rail train operation is completely dependent on the aerial track suspended from its upper part, because the lower part of the carriage is suspended in the air without support and cannot obtain longitudinal and lateral control from the lower part. The traction conne...
