Bo steering frame used for electric shunting locomotive

Abstract

The invention discloses a Bo steering frame used for an electric shunting locomotive. The Bo steering frame comprises a framework, two wheel pairs and two sets of basic braking devices used for braking the wheel pairs. The framework comprises two parallel framework side beams and three framework transverse beams used for enabling the framework side beams to be connected into a whole. The three framework transverse beams comprise two end portion transverse beams located on the end portions of the two ends of the framework side beams and one middle transverse beam located in the middle of the transverse side beams, the framework side beams and the framework transverse beams define a first empty position and a second empty position in an enclosed mode, the two wheel pairs are installed in the first empty position and the second empty position respectively through axle boxes, and the two sets of the basic braking devices are installed on the two end portion transverse beams respectively. Compared with a current Bo steering frame, the axial distance of the Bo steering frame is smaller, and accordingly a curve with a smaller radius can pass the steering frame and the developing requirements of an existing shunting locomotive are met.

Description

technical field [0001] The invention relates to the technical field of rail vehicle bogies, in particular to a Bo bogie for electric shunting locomotives. Background technique [0002] Shunting locomotives are indispensable traction vehicles for trunk line and branch line railway rescue, marshalling stations and shunting yards for train marshalling, unmarshalling, small-run shunting operations, and the initial stage of subway construction. It has a wide range of applications. [0003] At present, the widely used shunting locomotives in China are mainly diesel locomotives, such as Dongfeng 5, Dongfeng 7, Dongfeng 10D and other series of diesel locomotives, which are basically transformed from freight locomotives. The existing bogies of internal combustion engine shunting locomotives generally adopt the traditional Co three-axle bogie, which includes three wheel sets, and the requirement that the shunting locomotive needs to meet is to have a relatively large starting speed, s...

AI Technical Summary

Problems solved by technology

Bogies generally include a frame at the top, an axle box arranged below the top frame and used for mounting wheelsets, a series of vertical suspension mechanisms arranged between the axle box and the frame, and a series of vertical suspension mechanisms arranged between the top frame and the vehicle. The secondary vertical suspension mechanism between the bogies, the frame of the Bo bogie is also equipped with a foundation brake device, and the foundation brake device used to brake the Bo bogie is installed on the middle beam of the frame, that is, the two Each foundation brake device is located between the two wheel sets, which will take up a large installation space and make the wheelbase between the two wheel sets larger, and the larger wheelbase is obviously not suitable for passing through the smaller radius the curve
