Single-rail bogie central suspension device provided with aluminum alloy connection sleeper beam

Abstract

The invention discloses a single-rail bogie central suspension device provided with an aluminum alloy connection sleeper beam. The single-rail bogie central suspension device is characterized in that a center pin is connected with a connection sleeper beam; two air spring seat holes in the lower surface of the connection sleeper beam are connected with air springs; a height adjusting device consists of a height valve, a horizontal rod, an upper spherical hinge, a lower spherical hinge, an upper double-end stud, a lower double-end stud and a helical buckle; the upper double-end stud and the lower double-end stud are reverse in rotation directions and construct a bidirectional screw-nut mechanism together with a middle helical buckle; one end of the height valve is fixed to a train body; the other end of the height valve is connected with the horizontal rod; the horizontal rod is connected with the upper end of the screw-nut mechanism through the upper spherical hinge; the lower end of the screw-nut mechanism is connected with a bogie truss through the lower spherical hinge; one end of an anti-rolling steel wire rope is fixed to the connection sleeper beam through a hoisting base; a circular block at the other end is limited through a blocking base on the truss. By adopting the single-rail bogie central suspension device, the connection sleeper beam is provided, so that the stress state of a chassis of an aluminum train body is improved greatly, and convenience is brought to height adjustment of the train body; the single-rail bogie central suspension device has a simple structure and high adjustment accuracy; the anti-rolling safety coefficient of the train body under the working condition of heavy wind is increased greatly through the anti-rolling steel wire rope.

Description

technical field [0001] The invention belongs to the technical field of monorail vehicle bogies, in particular to a central suspension device of a two-axle straddle type monorail bogie. Background technique [0002] At present, the known central suspension device of a traditional two-axle straddle monorail bogie consists of an air spring, a central pin, a draw beam, a traction rubber pile, a traction rubber pile mounting seat, a transverse buffer, a transverse buffer mounting seat, and a transverse shock absorber. , vertical stop, height adjustment device and other components. In this kind of central suspension device, the center pin of the bogie is connected to the middle part of the aluminum car body chassis, which causes severe stress in this area of ​​the car body chassis and insufficient strength margin; the height adjustment device is a horizontal rotary type, consisting of a lever seat, It consists of a rotating arm, a U-shaped rod, a horizontal rod, and a height valv...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that in the design of the central suspension device of the existing monorail bogie, the force on the underframe area of ​​the car body is bad, the structure of the height adjustment device is complicated and the sensitivity is low, and there is no anti-rolling (overturning) device.
