Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Most preferred embodiment:
As shown in Figure 1, 2, 3, a kind of non-power truck for 100% low floor vehicle, comprise framework 16 and two wheel shafts 8, described framework 16 comprises the curb girder that two middle parts are recessed and be parallel to each other and is connected between the recessed portion at two curb girders middle parts and the crossbeam being parallel to each other.Curb girder is the bow-shaped structural that weathering steel assembly welding forms, to reduce the height of base plate; Crossbeam adopts solid drawn pipe, to reduce the weight of entirety of the present invention.
Described wheel shaft 8 two ends from inside to outside connect successively axle box 20, elastic wheel 9 and brake disc 17 and are arranged on curb girder bottom by single stage suspension mount pad 23 and the single stage suspension 21 of axle box 20 front and back ends.Between the axle box 20 of described two wheel shafts 8 with end, connect electromagnetic rail brake device 5, every wheel shaft one end connecting earthing device 2, the other end connects tachogen 6.Described wheel shaft 8, because diameter is little, therefore adopts solid axle structure, and elastic wheel 9 adopts V-type elastic wheel, can vibration-absorbing denoising.Axle box 8 tops are also provided with safe stop, ensure that vehicle can also safe operation after single stage suspension et out of order.
Recessed portion inner side, described curb girder middle part is fixedly installed horizontal backstop 12, described two crossbeam two ends are jointly stretched out outside curb girder and secondary suspension mount pad 22 are set in end, on this secondary suspension mount pad 22, secondary suspension 3 is set, vertical backstop 18 and vertical bumper 13, the same side of described two curb girders is drawing pull bar 1 of detachable connection respectively, on different ends, transverse damper 10 and brake clamp 19 are set respectively, brake clamp 19 is connected with brake fluid pressure unit 15 and energy storage 14, except drawing pull bar 1, all the other all distribute according to framework 20 central point above-mentioned each parts.Described horizontal backstop 12 and transverse damper 10 arrange taking framework 16 center as center of symmetry skew symmetry, and laterally backstop 12 is for limiting car body and relative displacement of 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 rubber pads thereof, and this structure can ensure vertical stiffness and lateral stiffness, meets dynamic (dynamical) requirement.Secondary suspension 3 is arranged on curb girder outside, has increased the transverse pitch of the secondary suspension 3 at same crossbeam two ends, and support effect is better, no longer needs anti-side rolling torsion rod.Described vertical backstop 18 and vertical bumper 13 arrange taking framework 16 center as center of symmetry skew symmetry, and vertical backstop 18 is for limiting the relative displacement between car body and the present invention, and vertical bumper 13 is for slowing down the speed of car body vertical deviation.
Outside the curb girder of described framework 16, corresponding elastic wheel 9 is fixedly installed mud guard 11.Mud guard 11, for stopping mud pollution car body and the present invention of elastic wheel 9, can also have and absorb and deadening effect fricative noise between wheel track.
Rim lubricating device 7 is also set, the wheel rim position of corresponding elastic wheel 9 on described curb girder.Rim lubricating device 7 adopts without air lubrication systems, and this device both can be lubricated according to circuit bend signal, can also detect bend and be lubricated according to the controller of himself, greatly reduces wheel-rail wear and the noise of the present invention in the time of bend.
Except drawing pull bar 1, all the other all distribute according to the central point of framework 16 above-mentioned each parts.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
