Abstract
The utility model discloses a positioning joint of a train bogie. The positioning joint is characterized in that conical bosses are arranged at two ends of a metal positioning shaft, each conical boss is provided with two large ends shrunk towards the center, and the two conical bosses at both ends are conical bosses smaller than half-circles in shape. A square groove is arranged in the middle of one end of the metal positioning shaft, mounting holes are disposed at two ends of the metal positioning shaft, rubber layers are arranged on the two conical bosses in axial directions of the metal positioning shafts and in the middle section, between the two conical bosses, of the positioning shaft, metal outer sleeves are arranged on the peripheries of the two rubber layers, a cylindrical hole is disposed on one metal outer sleeve, and rubber of the rubber layers respectively fixedly connects the two conical bosses in the axial directions and the middle section of the positioning shaft with the metal outer sleeves by means of vulcanization. The positioning joint of a train bogie can reduce train vibration and noise, can improve flexibility of a train and running quality of the train, and realize safer running of the train.
Description
Technical field
The utility model relates to a kind of location node, especially a kind of location node of rail vehicle bogie truck.
Background technology
In train travelling process, when especially reaching bend in train is run at high speed, the rigidity structure of train makes train vibration and noise all big especially, and poor stability and riding quality when making train operation are low.
Summary of the invention
The purpose of this utility model provides a kind of location node of rail vehicle bogie truck.This location node can lower the train vibrations and reduce noise, can improve the flexibility of vehicle and improve the train operation quality.Make vehicle operating safer.
The technical solution of the utility model is: a kind of location node of rail vehicle bogie truck.It is big to centre contraction bevelled cone boss that metal fix shaft two ends are provided with two ends, and two cone bosses at two ends are the cone boss less than the semicircle loop-shaped.Have square groove in the middle of metal fix shaft one end.End, metal fix shaft two ends is provided with mounting hole.
Each is provided with rubber layer on two cone bosses and on the fix shaft interlude between two cone bosses on axially at the metal fix shaft.
Two rubber layer peripheries are provided with metal-coating.Metal-coating is the outward-dipping lopsided circular arc shape of double headed roller.Have cylindrical hole on one metal-coating.
Axially last two cone bosses, fix shaft interlude and metal-coating vulcanize affixed being integral to the rubber of rubber layer with each respectively.
Described location node serviceability temperature is-40 ℃～+ 40 ℃.Rubber hardness is 48～52 Shao Er degree, be permanently deformed to less than 20%, tensile strength is greater than 16MPa, breaking elongation is greater than 400%, the bind strength of cone boss, fix shaft stage casing and metal-coating and rubber is for being not less than 5MPa, and the insulating resistance value between metal fix shaft and the metal-coating is for being not less than 100 megaohms.
The utility model has the advantages that the location node that a kind of rail vehicle bogie truck is provided.This location node can lower the train vibrations and reduce noise, can improve the flexibility of vehicle and improve the train operation quality.Make vehicle operating safer.
