Problems solved by technology

The existing underframe and the bogie are only connected by the center pin, so that the bogie and the underframe move synchronously, no other limiting and connecting components are set, and the combination between the bogie and the underframe is in the process of transportation and operation. It is not safe enough, there is a risk of loosening on bumpy or sloping roads, and there is also a risk of excessive deflection of the bogie due to the rotational inertia on bends

Abstract

The invention discloses an anti-loosening steering frame of a railway vehicle. The anti-loosening steering frame of the railway vehicle comprises a side frame, a swing bolster, a central pin and a limiting connection piece, wherein the central pin is arranged in the middle of the swing bolster; an elastic side bearing assembly is arranged between the central pin and the side frame; the lower end of the elastic side bearing assembly is arranged on the swing bolster; the lower end of the limiting connection piece is connected with the swing bolster; a joint of the lower end of the limiting connection piece and the swing bolster is positioned between the elastic side bearing assembly and the side frame; the upper end of the limiting connection piece is connected with a vehicle under-frame; the height difference and the horizontal distance between the upper end and the lower end of the limiting connection piece can be changed in a predetermined range. According to the anti-loosening steering frame of the railway vehicle, the safety of combination of the steering frame and the vehicle under-frame can be improved on the premise that free steering of the steering frame in an allowed range is not affected.

Description

technical field [0001] The invention relates to an anti-off bogie for a railway vehicle, which belongs to the technical field of railway equipment manufacturing. Background technique [0002] The underframe of the railway vehicle is connected with the bogie through the central pin, so as to realize the support of the bogie to the underframe and make the underframe have flexible steering ability. The existing underframe and the bogie are only connected by the center pin, so that the bogie and the underframe move synchronously, no other limiting and connecting components are set, and the combination between the bogie and the underframe is in the process of transportation and operation. It is not safe enough, there is a risk of loosening on bumpy or certain slope roads, and there is also a risk of excessive deflection of the bogie due to the rotational inertia on bends. Therefore, it is necessary to improve the existing bogie and add reasonable limit connectors to reduce the a...
