Problems solved by technology

However, as the speed of the locomotive increases, the dynamic performance of the locomotive decreases significantly due to the large inter-sprung mass of the bogie with this structure, which is generally reflected in the lateral shaking of the locomotive, the peeling of the tread, and the large lateral force of the wheel and rail.
It affects the riding comfort of the locomotive, accelerates the damage of the force-bearing parts of the running part, and even affects the driving safety

Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiments.

[0019] It can be seen from the accompanying drawings 1-2 that the present invention is a three-axle locomotive bogie. The traction motors of each axle on the three-axle bogie adopt different suspension methods, and then the three axles of the bogie are combined. , forming a composite bogie traction motor frame suspension structure combining elasticity and rigidity. Among them, the traction motors at both ends adopt the method of elastic suspension, and the traction motors at both ends are suspended on the frame through elastic suspension devices composed of elastic elements, that is, one end of the traction motor is directly suspended on the frame through elastic joints. The other end is suspended on the frame of the bogie by an elastic suspender, and its horizontal connection is elastic, so that the traction motor can swing around the frame of the bogie elastically up and ...

Abstract

A tractive motor suspending method and steering bogie of three-axle locomotive features that the tractive motors on the three-axle steering bogie are respectively suspended in different modes, that is, the elastic suspending mode is used for two side motors and the rigid suspending mode is used for middle motor, and three axles of steering bogie are combined, resulting in high transverse dynamic properties of locomotive.

Description

technical field [0001] The invention belongs to a component structure of an electric locomotive, in particular to a traction motor suspension method and a bogie for an electric locomotive bogie, and is especially suitable for high-speed or quasi-high-speed locomotives of C0-C0 axle type. technical background [0002] The traction motor is the power source of the electric locomotive, and the traction motor is mostly suspended on the bogie of the electric locomotive. The bogies of electric locomotives have different structures according to different locomotives, usually there are two-axle bogies, three-axle bogies, etc. At present, the domestic existing C0-C0 axle type high-speed or quasi-high-speed locomotive bogie is a kind of three-axle bogie, and the traction motor rigid frame suspension structure is adopted on this three-axle bogie. The advantages of this kind of bogie are The motor is rigidly fixed on the frame, and the mass of the motor belongs to the intersprung mass....
