Embodiment Construction

[0051] A three-axle radial bogie for an electric locomotive, such as figure 1 and 11 As shown, it is a three-axle structure, which is mainly assembled by three sets of wheel-to-axle boxes 1, three sets of drive units 2, a frame 3, a set of primary suspension devices 4, a set of secondary suspension devices 5, and a set of traction devices 6. It is composed of three sets of motor suspension devices 7, one set of brake devices 8, and one set of radial devices 9.

[0052] Such as figure 2 and 12 As shown, a kind of electric locomotive triaxial radial bogie wheel-to-axlebox assembly 1 provided by the embodiment of the present invention consists of grounding device 11, axlebox body 12, axlebox bearings 13, 17, wheels 14, axle shaft 15, speed sensor 16. Two wheels 14 are press-fitted on each axle 15; axle box bearings 13, 17 are also pressed on the journals at both ends of each axle 15, and the axle box bearing 13 is axially assembled with one wheel axle and three axles axially...

Abstract

The invention discloses a locomotive three-axis radial bogie. In order to reduce wheel set abrasion and improve the curve passing performance of a locomotive, the locomotive three-axis radial bogie is mainly composed of three sets of wheel set shaft box assemblies, three sets of driving units, a framework, a single stage suspension device, a secondary suspension device, a set of traction device, three motor suspension devices, a brake device, and a radial device. The framework is mainly composed of a front end beam, two side beams, a traction beam, a middle beam, and a back end beam. The radial device is mainly composed of a pivot, a front guide beam, a transition coupling pull rod, a supporting rod, a turning arm, a coupling pull rod, and a back guide beam. The locomotive three-axis radial bogie has the capacity of automatically tending to a radial position, improves the curve passing speed of the locomotive, and reduces wheel set angle of attack, and reduces wheel rail transverse force, so that wheel rail abrasion is reduced, and the curve passing performance of the locomotive is improved.

Description

technical field [0001] The invention relates to the field of railway heavy-duty freight locomotives, in particular to a locomotive three-axis radial bogie. Background technique [0002] When the railway locomotive bogie passes the curve, it must rely on the guidance of the wheel rim to ensure that the bogie runs along the track. At this time, there is lateral contact between the side of the rail and the wheel rim, and the surface is squeezed and rubbed, resulting in wear of the wheel and rail. The main influencing factors of wear are the angle of attack of the wheel and the lateral force of the wheel and rail. Ordinary locomotive bogie wheel sets cannot rotate relative to the frame, so when passing through a curved track, a large angle of attack is formed between the wheel set and the track, resulting in additional wheel-rail wear, and the smaller the radius of the curve, this The situation is more obvious. For heavy-duty freight three-axle bogies, due to the heavy axle, ...
