Abstract
The utility model provides a horizontal buffer of a train bogie. The horizontal buffer comprises a stop shaft and a rubber stop, wherein the stop shaft is made of metal material; the right end of the stop shaft adopts a big oblate cylinder; the left end of the stop shaft adopts a slender cylinder; the left end part of the slender cylinder is slightly thicker than the middle of the slender cylinder; the rubber stop is made of rubber material, and adopts a tapered hollow cone with a think right end and a thin left end; the right end part of the tapered hollow cone is clung to the big oblate cylinder of the stop shaft; the inner ring of the tapered hollow cone is mounted on the outer ring in the middle of the slender cylinder in a jacketing manner; and the stop shaft and the rubber stop are vulcanized and fixedly connected into a whole through the rubber of the rubber stop. The utility model has the advantages that the structural flexibility of a train can be improved; inclination, vibration and noise generated during the running of the train can be reduced; and the running safety and the running quality of the train can be improved.
Description
Technical field
The utility model relates to a kind of horizontal buffer, particularly a kind of horizontal buffer of train bogie truck.
Background technology
In train travelling process, especially when train was run at high speed and cross bend, the rigidity structure of train made train inclination, vibration and noise all big especially, and poor safety performance and riding quality when making train operation are low.
Summary of the invention
The purpose of this utility model provides a kind of horizontal buffer of train bogie truck.This horizontal buffer can improve the flexibility of vehicle structure, can alleviate inclination, vibration and noise in the train travelling process, can improve the quality of the safety and the operation of vehicle operating.
The technical solution of the utility model is: a kind of horizontal buffer of train bogie truck, it comprises gear shaft and rubber stop.
Described gear shaft adopts metallic material to make.The gear shaft right-hand member is big oblate cylinder, and the gear shaft left end is a slender cylinder.The slender cylinder left part is slightly thicker than the slender cylinder middle part.
Described rubber stop adopts elastomeric material to make.The thick left end of this rubber stop right-hand member approaches tapered hollow cone body.This tapered hollow cone right part is near the big oblate cylinder of gear shaft.Tapered hollow cone inner ring is sleeved on the outer ring, slender cylinder middle part.
Described gear shaft and rubber stop are integral by the vulcanization of rubber of rubber stop is affixed.
The hardness of the rubber of described rubber stop is 60 ± 5 Shao Er degree, and tensile strength at break is for being not less than 14.7MPa, and setafter break is for being not more than 20%, and elongation at failure is for being not less than 400%, and brittleness temperature is for being not more than-50 ℃.Behind 70 ℃ of 72h of hot air aging, the tensile strength at break rate of change is less than 15%, and the elongation at failure rate of change is less than 15%.
The utility model has the advantages that the horizontal buffer that a kind of bogie truck is provided.This horizontal buffer can improve the flexibility of vehicle structure, can alleviate inclination, vibration and noise in the train travelling process, can improve the quality of the safety and the operation of vehicle operating.
