Embodiment Construction

[0034] Below by specific embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0035] The axle box positioning method of the present invention is as figure 1 As shown: the axle box 3 is elastically connected to the frame 1 through the spring 4. Since the spring 4 has a relatively large stiffness in the vertical direction (Z), it can meet the vibration reduction requirements of the rail vehicle, but in the longitudinal direction (X) and vertical direction along the track The lateral (Y) stiffness of the track is small and cannot provide the rigidity required for longitudinal and lateral positioning. As a result, during the running of the rail vehicle, the axle box 3 swings greatly in the longitudinal (X) and lateral (Y) directions, which cannot meet the positioning requirements of the axle box. Of course, pivoting arm type axle box positioning or pull rod type positioning can be used, but these positioning methods have comp...

Abstract

The invention relates to an axle box positioning method, an axle box overhead node and a rail vehicle, the axle box is located by arranging an axle box overhead rubber node with small vertical rigidity and large radial rigidity at the top of the axle box, so that the vertical rigidity, the longitudinal rigidity and the transverse rigidity of an axle box spring can be decoupled, and the positioningstructure of the axle box is simplified; and the cost is reduced. The axle box overhead joint is of a metal rubber composite structure with multiple layers of annular spacer bushes, and the spacer bushes are of a split structure so that the axle box overhead rubber joint can be pre-compressed, and the radial rigidity can be further improved. Meanwhile, an axial cavity is formed in the axle box overhead rubber joint, so that the rigidity of the axle box overhead joint in different radial directions is different, and different rigidity requirements required by axle box positioning in the longitudinal direction and the transverse direction are met.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to an axle box positioning method, an axle box overhead node and a rail vehicle. Background technique [0002] As the load-bearing, vibration-damping and running mechanism of rail vehicles, the bogie is usually composed of two suspension systems, one of which is set between the axle box and the frame, and its main functions are load-bearing, vibration-damping and positioning. The axle box positioning methods are divided into: frame positioning and frameless positioning. Among them, the frameless positioning methods include: guide frame type, pillar type, oil guide cylinder type, rotary arm type, pull rod type, pull plate type, rubber spring type, etc. The axlebox positioning usually adopts the pivot arm type axlebox positioning or the pull rod type positioning, but these two positioning methods make the structure of the axlebox positioning complex and occupy a larg...
