Abstract
The present invention is a kind of horizontal buffer of train bogie, and it comprises gear shaft and rubber stop.Described gear shaft adopts metallic material to make.Gear shaft right-hand member is large oblate cylinder, and gear shaft left end is slender cylinder.Slender cylinder left part is than slightly thick in the middle part of slender cylinder.Described rubber stop adopts elastomeric material to make.The thin tapered hollow cone of the thick left end of this rubber stop right-hand member.This tapered hollow cone right part is near the large oblate cylinder of gear shaft.Tapered hollow cone inner ring to be sleeved in the middle part of slender cylinder on outer ring.Described gear shaft and rubber stop affixed integral by the vulcanization of rubber of rubber stop.The present invention can improve the flexibility of vehicle structure, can alleviate the inclination in train travelling process, vibration and noise, can improve the safety of vehicle operating and the quality of operation.
Description
Technical field
The present invention relates to a kind of horizontal buffer, particularly a kind of horizontal buffer of train bogie.
Background technology
In train travelling process, especially when train is run at high speed and cross bend, the rigid structural of train makes train tilt, vibration and noise large all especially, and poor safety performance when making train operation and riding quality low.
Summary of the invention
The object of this invention is to provide a kind of horizontal buffer of train bogie.This horizontal buffer can improve the flexibility of vehicle structure, can alleviate the inclination in train travelling process, vibration and noise, can improve the safety of vehicle operating and the quality of operation.
Technical scheme of the present invention is: a kind of horizontal buffer of train bogie, and it comprises gear shaft and rubber stop.
Described gear shaft adopts metallic material to make.Gear shaft right-hand member is large oblate cylinder, and gear shaft left end is slender cylinder.Slender cylinder left part is than slightly thick in the middle part of slender cylinder.
Described rubber stop adopts elastomeric material to make.The thin tapered hollow cone of the thick left end of this rubber stop right-hand member.This tapered hollow cone right part is near the large oblate cylinder of gear shaft.Tapered hollow cone inner ring to be sleeved in the middle part of slender cylinder on outer ring.
Described gear shaft and rubber stop affixed integral by the vulcanization of rubber of rubber stop.
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 DEG C.After hot air aging 70 DEG C of 72h, tensile strength at break rate of change is for being less than 15%, and elongation at failure rate of change is for being less than 15%.
Advantage of the present invention there is provided a kind of horizontal buffer of bogie truck.This horizontal buffer can improve the flexibility of vehicle structure, can alleviate the inclination in train travelling process, vibration and noise, can improve the safety of vehicle operating and the quality of operation.

Detailed description of the invention
As shown in the FIG.: a kind of horizontal buffer of train bogie, it comprises gear shaft 9 and rubber stop 1.
Described gear shaft 9 adopts metallic material to make.Gear shaft 9 right-hand member is large oblate cylinder 6, and gear shaft 9 left end is slender cylinder 8.Slender cylinder left part 5 is thicker than 7 summaries in the middle part of slender cylinder.
Described rubber stop 1 adopts elastomeric material to make.The thin tapered hollow cone 2 of the thick left end of this rubber stop 1 right-hand member.This tapered hollow cone right part 3 is near the large oblate cylinder 6 of gear shaft 9.Tapered hollow cone inner ring 4 to be sleeved in the middle part of slender cylinder on 7 outer rings.
Described gear shaft 9 is affixed integral by the vulcanization of rubber of rubber stop 1 with rubber stop 1.
The hardness of the rubber of described rubber stop 1 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 DEG C.After hot air aging 70 DEG C of 72h, tensile strength at break rate of change is for being less than 15%, and elongation at failure rate of change is for being less than 15%.
