Abstract
The invention provides a 25-meter curve radius metro bogie, comprising a framework, a wheelset axle box device, a secondary suspension device, a foundation brake device and a driving device. The 25-meter curve radius metro bogie is characterized in that an air spring of the secondary suspension device is connected with a swing bolster lower cover plate; a bearing mounting seat is welded in the middle of a swing bolster lower cover plate and is used for mounting a spherical bearing; and an inner ring of the spherical bearing is connected with a vehicle body sleeper beam, and an outer ring of the spherical bearing is connected with the bearing mounting seat. According to the invention, the way a turntable bearing is added to the swing bolster is adopted and thus the rotation between a vehicle body and the bogie is realized through rotating the bearing inner ring and the outer ring, and further guarantee the vehicle passes through a 25-meter curve radius.
Description
Technical field
the present invention relates to a kind of metro bogie, especially relate to a kind of 25 meters radius of curve metro bogies that pass through.
Background technology
The environmental conditions of
modern city rail line is widely different, for each bar rail line of independent operating, imposes the whole nation, the whole city to unify minimal curve radius and has little significance.Bogie truck is a railway vehicle traveling portion, and the metro bogie of 25m radius of curve is a kind of bogie truck of special purpose, is applicable to the circuit of radius of curve at 25m ~ 80m.At present state, inside and outside most subway lines be radius of curve greater than 80m, the bogie truck that is suitable for this radius of curve all adopts no bolster structural shape; The radius of curve of the few countries and the subway line in area is below 80m; In order to satisfy vehicle through 25m radius of curve performance requriements; The corner that goes out bogie truck and car body according to calculation of parameter such as length between truck centers, the horizontal spans of air spring is 15. 4 degree to the maximum, the nearly 260mm of the maximum displacement of air spring, and displacement capabilities reaches 260mm at present; The air spring does not exist load-carrying capacity in the 10.5t left and right sides, can not meet the demands.
Summary of the invention
technical matters to be solved by this invention provides a kind of bogie truck that satisfies 25 meters radius of curve, can pass through 25 meters radius of curve subway lines so that assemble the vehicle of this bogie truck.
are for solving the problems of the technologies described above; The present invention provides a kind of 25 meters radius of curve metro bogies, comprises framework, wheel to axle box device, secondary suspension device, foundation brake rigging, actuating device, and it is characterized in that: the air bellow of secondary suspension device connects the bolster lower cover; Bolster upper cover plate middle part is welded with the bearing installation seat; Be used to install ball-bearing casing, the inner ring of ball-bearing casing links to each other with the car body sleeper beam, and ball bearing outer ring links to each other with the bearing installation seat.
the present invention adopts the pattern that adds turntable bearing on the bolster, through the rotation of bearing inner ring and outer ring, realizes the rotation between car body and the bogie truck, thereby guarantees that vehicle is through 25 meters radius of curve.
Description of drawings
accompanying drawing is the bogie structure scheme drawing.
The specific embodiment
are with reference to accompanying drawing; The present invention includes truck frame 1, wheel to axle box device 2, secondary suspension device 3, foundation brake rigging 5, actuating device 6 compositions, the air bellow of secondary suspension device connects bolster 4 lower covers, and bolster upper cover plate middle part is welded with bearing installation seat 8; Be used to install 1 meter major diameter ball-bearing casing 7; The inner ring of ball-bearing casing links to each other with the car body sleeper beam with bolt, and ball bearing outer ring links to each other with the bearing installation seat with bolt, through the rotation of ball bearing inner race and outer ring; Realize the rotation between car body and the bogie truck, thereby guarantee that vehicle is through the 25m curve.
