Abstract
The invention relates to a horizontal buffer for a bogie frame of a train. The horizontal buffer comprises a buffer shaft and a rubber buffer, wherein the buffer shaft is made of metallic materials; a big flat cylinder is arranged at the right end of the buffer shaft; a thin and long cylinder is arranged at the left end of the buffer shaft; the left end of the thin and long cylinder is thicker than the middle of the thin and long cylinder; the rubber buffer is made of rubber materials; the rubber buffer is a tapered hollow cone with a thick right end and a thin left end; the right end of the tapered hollow cone is next to the big flat cylinder of the buffer shaft; an inner circle of the tapered hollow cone is sleeved on an outer circle in the middle of the thin and long cylinder; and the rubber vulcanization of the rubber buffer is utilized to fixedly and integrally connect the buffer shaft with the rubber buffer. The horizontal buffer provided by the invention can be used for promoting the structural flexibility of the train, relieving the incline, vibration and noise of the train during a running process, and promoting the running safety and running quality of the train.
Description
Technical field
The present invention 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 horizontal buffer that the purpose of this invention is to provide a kind 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.
Technical scheme of the present invention is: a kind of horizontal buffer of train bogie truck, it comprises gear shaft and rubber stop.
Described gear shaft adopts metallic material to process.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 process.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%.
Advantage of the present invention has provided a kind of horizontal buffer of 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.
