Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described in detail.
Most preferred embodiment:
As shown in Figure 1, 2, 3, a kind of non-powered bogie for 100% low floor vehicle, including framework 16 and two wheel shafts 8, described framework 16 includes that two middle parts are recessed and the curb girder that is parallel to each other and the crossbeam being connected between the recessed portion in the middle part of two curb girders and being parallel to each other.Curb girder is the bow-shaped structural of weathering steel assembly welding, in order to reduce the height of base plate；Crossbeam uses seamless steel pipe, in order to reduce the weight that the present invention is overall.
Described wheel shaft 8 two ends are from inside to outside sequentially connected with axle box 20, elastic wheel 9 and brake disc 17 and single stage suspension mounting seat 23 and single stage suspension 21 by axle box 20 front and back end are arranged on bottom curb girder.Described two wheel shafts 8 are with connecting magnetic rail braking device 5, every wheel shaft one end connecting earthing device 2 between the axle box 20 of end, the other end connects speed probe 6.Described wheel shaft 8 is little due to diameter, therefore uses solid shafting structure, and elastic wheel 9 then uses V-type elastic wheel, can be with vibration-absorbing denoising.Axle box 8 top is additionally provided with safe stop, it is ensured that vehicle can also safe operation after single stage suspension breaks down.
Horizontal backstop 12 it is fixedly installed inside recessed portion in the middle part of described curb girder, described two crossbeam two ends are jointly stretched out outside curb girder and arrange secondary suspension mounting seat 22 in end, this secondary suspension mounting seat 22 arranges secondary suspension 3, vertical backstop 18 and vertical damper 13, the same side of described two curb girders piece drawing pull bar 1 of detachable connection respectively, it is respectively provided with transverse damper 10 and brake clamp 19 on different ends, brake clamp 19 is connected with brake fluid pressure unit 15 and accumulator 14, in addition to drawing pull bar 1, remaining is distributed above-mentioned each parts all in accordance with framework 16 central point.Described horizontal backstop 12 and transverse damper 10 are arranged with the center of framework 16 for symmetrical centre skew symmetry, and horizontal backstop 12 is for limiting the relative displacement of car body and the present invention, and transverse damper 10 is for slowing down the speed of cross-car displacement.Described secondary suspension 3 is made up of height circle spring and upper and lower two pieces of rubber blankets thereof, and this structure ensure that vertical stiffness and lateral stiffness, meets dynamic (dynamical) requirement.Secondary suspension 3 is arranged on side rail outer, adds the horizontal spacing of the secondary suspension 3 at same crossbeam two ends, and support effect is more preferable, it is no longer necessary to anti-side rolling torsion rod.Described vertical backstop 18 and vertical damper 13 are arranged with the center of framework 16 for symmetrical centre skew symmetry, and vertical backstop 18 is for limiting the relative displacement between car body and the present invention, and vertical damper 13 is for slowing down the speed of car body vertical deviation.
The side rail outer correspondence elastic wheel 9 of described framework 16 is fixedly installed mud guard 11.Mud guard 11 is for stopping mud pollution car body and the present invention of elastic wheel 9, it is also possible to have absorption and deadening effect to noise fricative between wheel track.
Secondary suspension 3 in described secondary suspension mounting seat 22 has two groups, is provided with boom hoisting 4 between two groups.
Rim lubricating device 7, the rim location of corresponding elastic wheel 9 is also set up on described curb girder.Rim lubricating device 7 uses without air lubrication systems, and this device both can be lubricated according to circuit bend signal, it is also possible to detects bend according to the controller of himself and is lubricated, being greatly reduced the present invention wheel-rail wear when bend and noise.
Above-mentioned each parts in addition to drawing pull bar 1 remaining all in accordance with framework 16 central point be distributed.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
