Each air spring 5 connects a height adjuster, two height adjusters are symmetricly set on the both sides of curb girder 1, height adjuster includes that big flow automatic height adjusts valve 6 and adjusting lever 7, automatic height adjusts valve 6 and is serially connected between wind regime with air spring 5 on the pipeline being connected, and adjusting lever 7 adjusts valve 6 with automatic height and is connected.When vehicle actual motion, along with the change of deadlight load, automatic height adjustment valve 6 air feed is still by the outside air draft of air spring 5 in air spring 5 to control wind regime, constant with the height maintaining air spring 5.In the present embodiment, select big flow automatic height to adjust valve 6, the inflationtime of air spring 5 can be shortened, make air spring 5 can inflate rapidly the requirement reaching height and pressure, meet the demand of big handling capacity of passengers.Further, since two air springs 5 are separately fixed on two curb girders 1, the horizontal span between two air springs 5 is relatively small, meets vehicle gauge requirement.
Drive system includes gear-box 8 and traction electric machine 9, and the casing of gear-box 8 is the split-type structural being made up of aluminium alloy.Gear train in gear-box 8 is fitted on axletree 10.The quantity of gear-box 8 and traction electric machine 9 is two, arranged in a crossed manner on two crossbeams 2 in diagonal respectively, traction electric machine 9 is fixed on the crossbeam 2 of correspondence by motor mount 11, to ensure the moving equilibrium of two groups of axle systems, improves the stability of motor car bogie simultaneously.In order to meet speed per hour 120 kilometers, the administrative region of a city fast rail vehicle high requirement to opening soon soon stopping of axle weight 20t, in the present embodiment, through substantial amounts of computational analysis, the gear ratio of gear-box 8 is preferably greater than 7, much larger than of the prior art 3.036.
Axle system includes axletree 10 and is arranged on the wheel at axletree two ends to 12, it is respectively mounted axle box 13 at the two ends of axletree 10, axle box 13 uses pivoted arm axle box, single stage suspension is installed between axle box 13 and curb girder 1, single stage suspension uses steel coil spring 14, is additionally provided with a vertical damper 15 between each axle box 13 and curb girder 1.
Disc brake uses wheel disc caliper brake 16, wheel disc caliper brake 16 is set to four, corresponding each wheel arranges one, four wheel disc caliper brakes 16 are fixedly mounted on the curb girder 1 of correspondence by braking mounting seat 17, wheel is provided with brake disc, in the present embodiment, uses the brake disc of big abrasion loss, the abrasion loss of brake disc is all at more than 5mm, with the requirement meeting big handling capacity of passengers, rise soon soon stop.
In the present embodiment, use two drawing pull bar devices, it is arranged at the inner side of curb girder 1, a drawing pull bar seat (not shown) it is respectively arranged with wherein on two crossbeams 2, one end of two drawing pull bar connects centrepin 19, the other end is arranged on the drawing pull bar seat on the crossbeam 2 of correspondence, and centrepin 19 is connected by bolt 20 is fixing with the bottom of car body.
In the present embodiment, installing pantagraph current collector 21 on two axle boxes 13 of homonymy, pantagraph current collector 21 is fixedly mounted on pantagraph current collector and installs on crossbeam 22, and crossbeam 22 installed by pantagraph current collector is an elongated insulation fabric part, its two ends are connected with two axle boxes 13 of homonymy, and then are arranged on bogie by pantagraph current collector 21.
Bogie is owing to have employed pivoted arm axle box, bogie is made to be restricted for the space installing pantagraph current collector 21, narrow space as well as the 3rd rail of power supply, pantagraph current collector is installed the two ends elasticity of crossbeam 22 and is connected to the bottom of axle box 13 by this mounting structure, so can eliminate the impact on piston shoes space of the bogie primary amount of deflection.
Pantagraph current collector is installed one end of crossbeam 22 and is connected with a connecting seat 24 by the first elastic panel nodes 23, and a connecting seat 24 is by multiple box bottom being bolted to axle box 13.Pantagraph current collector is installed the other end and the 3rd of crossbeam 22 and is connected the fixing connection of seat 28,3rd connects seat 28 is connected with suspension rod 18 bottom by the 3rd elastic panel nodes 27, the top of suspension rod 18 is connected seat 26 by the second elastic panel nodes 25 with second and connects, and second connects seat 26 by multiple box bottom being bolted to axle box 13.
Rail vehicle is in running, when load change or excessively bend, two groups of pivoted arm axle boxes of bogie can rotate or relative displacement accordingly, a connecting seat 24 and the second distance connected between seat 26 is caused to change, as, when a connecting seat 24 and the second distance connecting seat 26 become big (bogie longitudinal direction), first elastic panel nodes 23, second elastic panel nodes 25, 3rd elastic panel nodes 27 and suspension rod 18 can adapt to this change, suspension rod 18 deflects certain angle counterclockwise, relatively increase pantagraph current collector and the length being connected between crossbeam 22 and two axle boxes 13 is installed.When a connecting seat 24 and the second distance connecting seat 26 diminish (bogie longitudinal direction), first elastic panel nodes 23, second elastic panel nodes 25, 3rd elastic panel nodes 27 and suspension rod 18 are for adapting to this change, suspension rod 18 can be to deflecting certain angle clockwise, relatively reduce pantagraph current collector and the length being connected between crossbeam 22 and two axle boxes 13 is installed, the most preferably avoid vehicle load change or rotate due to axle box when crossing bend or produce relative displacement and cause that a connecting seat 24 and second connects the relative motion of seat 26 and the normal work on pantagraph current collector 21 produces impact in running, realize vertical decoupling.In vehicle operation, a connecting seat 24, second connects seat 26 and has essentially identical kinestate with axle box 13, by the elastic suspension structure of derrick type, control pantagraph current collector 21 relative to the displacement on vertical of the 3rd rail, reduction pantagraph current collector 21, to the 3rd rail space and the requirement of three rail bendings height, reaches safety in vehicle operation and is subject to stream, the steady purpose flowed.
As it has been described above, combine the plan content given by accompanying drawing, similar technical scheme can be derived.In every case it is the content without departing from technical solutions of the utility model, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, all still fall within the range of technical solutions of the utility model.
