Embodiment Construction

[0007] refer to figure 1 , the specific embodiment of the present invention includes a vertical bearing helical steel spring 1, a longitudinal positioning rubber spring 2, and a lateral positioning rubber spring 3. The three springs are placed vertically and arranged longitudinally, and the central position is a helical steel spring for bearing vertical loads. , providing vertical stiffness; two rubber springs are located on both sides of the helical steel spring, and are arranged symmetrically to the center of the helical steel spring. One of the rubber springs is used to undertake the longitudinal positioning of the axle box and provide longitudinal stiffness; the other rubber spring 3 is used to undertake the lateral positioning of the axle box and provide lateral rigidity. The primary suspension composition adopts an innovative structural design in which three springs are arranged in the same direction, and realizes two main functions: first, it realizes the separation of ...

Abstract

A three-direction decoupling type single stage suspension assembly arranged in the same direction is characterized by comprising three springs, wherein the three springs are placed vertically and arranged in the longitudinal direction; a spiral steel spring is arranged in the center of the assembly and is used for bearing vertical load and providing vertical rigidity; the two rubber springs are positioned on two sides of the spiral steel spring and are centrosymmetric along the spiral steel spring; one of the rubber springs is used for positioning an axle box in the longitudinal direction andproviding longitudinal rigidity; and the other rubber spring is used for positioning the axle box in the transverse direction and providing transverse rigidity. Separation of vertical rigidity, longitudinal rigidity and transverse rigidity of a single stage suspension is realized, and rigidities in three directions are decoupled; and furthermore, the diameter of a single spring is greatly reduced,therefore, occupation of the springs to the transverse space of a bogie is relieved, and space arrangement of the internal bogie of the axle box is facilitated greatly.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a series suspension structure composition for a bogie. Background technique [0002] As a load-bearing, vibration-damping and running mechanism, the bogie usually consists of two suspension systems, one of which is located between the wheel set and the frame. Its main functions are load-bearing, vibration-damping and positioning, and it is a key component of the bogie. The existing bogie primary suspension consists of two main structural forms: one is rubber springs; the other is spiral steel springs. Among them, rubber springs are mostly used in subways and light rail vehicles, and are suitable for bogies with low speed and small axle load. The characteristic is that rubber springs can also play the role of axle box positioning in addition to vertical load, that is, provide certain longitudinal positioning and lateral positioning. Stiffness, its disadvantage is...
