The specific embodiment
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 power truck for 100% low floor vehicle, comprise framework 20 and two wheel shafts 17, described framework 20 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 17 two ends from inside to outside connect successively axle box 16, elastic wheel 6 and brake disc 21 and are arranged on curb girder bottom by single stage suspension mount pad 26 and the single stage suspension 23 of axle box 16 front and back ends.Wheel shaft 17 diameters are little, therefore adopt solid axle structure, and elastic wheel 6 adopts V-type elastic wheel, can vibration-absorbing denoising.Axle box 16 tops are also provided with safe stop, guarantee that vehicle can also safe operation after single stage suspension et out of order.
Described wheel shaft 17 end connecting earthing devices 2.Described earth system 2, for facilitating the conduction of electric current, avoids electric current, by the bearing between wheel shaft 17 and elastic wheel 6, it is caused to damage.
Between the axle box 16 of described two wheel shafts 17 with end, connect electromagnetic rail brake device 3.Described electromagnetic rail brake device 3 can, according to the abrasion adjustment height of elastic wheel 6, be mainly used in the operating modes such as emergency brake of vehicle.
Top, described curb girder one end fixed electrical machinery 24, after slowing down, the reductor 13 in motor 24 output process curb girder outsides by elastic clutch 18, transmission of power is arrived to elastic wheel 6 again, sandbox 9 is established at curb girder other end top, Air compressor 1 is housed on sandbox 9, and recessed portion inner side, curb girder middle part is fixedly installed horizontal backstop 11.The same side of described two curb girders is drawing pull bar 22 of detachable connection respectively, on different ends, transverse damper 8 and brake clamp 27 is set respectively.Because motor 24, reductor 13 are arranged on framework 20, owing to existing amount of deflection to change, the mouth of reductor 13 and axle centerline be not on same axis, and it is the variation of amount of deflection that the amount of deflection of elastic clutch 18 just can meet one, guarantees that reductor 13 failure-freies transmit torque on wheel shaft 17.Described horizontal backstop 11 and transverse damper 8 arrange take framework 20 center as center of symmetry skew symmetry, and laterally backstop 11 is for limiting car body and relative displacement of the present invention, and transverse damper 8 is for slowing down the speed of cross-car displacement.
Described two crossbeam two ends are jointly stretched out outside curb girder and secondary suspension mount pad 25 are set in end, and secondary suspension 5, vertical backstop 12 and vertical bumper 15 are set on this secondary suspension mount pad 25.Secondary suspension 5 is made up of height circle spring and upper and lower two rubber pads thereof, and this structure can guarantee vertical stiffness and lateral stiffness, meets dynamic (dynamical) requirement.Secondary suspension 5 is arranged on curb girder outside, has increased the transverse pitch of the secondary suspension 5 at same crossbeam two ends, and support effect is better, no longer needs anti-side rolling torsion rod.Described vertical backstop 12 and vertical bumper 15 arrange take framework 20 center as center of symmetry skew symmetry, and vertical backstop 12 is for limiting the relative displacement between car body and the present invention, and vertical bumper 15 is for slowing down the speed of car body vertical deviation.
Brake clamp 27 is connected with release of brake unit 10 and brake fluid pressure unit 14, and above-mentioned each parts all distribute according to framework 20 central point except drawing pull bar 22.Brake clamp 27 uses for vehicle parking braking, under the control of brake fluid pressure unit 14, in clamped condition, under the control of release of brake unit 10, will brake releasing.
Outside the curb girder of described framework, corresponding elastic wheel 6 is fixedly installed mud guard 19.Mud guard 19, for stopping mud pollution car body and the present invention of elastic wheel 6, can also have and absorb and deadening effect fricative noise between wheel track.
On described sandbox 9, sand pipe is set, when Air compressor 1 starts, the sand in sandbox 9 is fallen on track below by sand pipe, can increase the binding force between wheel track, while effectively preventing from braking elastic wheel 6 lockings and start time elastic wheel 6 skid.
Described axle box 16 ends are fixed with pilot 7.This pilot 7 is made up of mount pad and troubleshooting rod, and troubleshooting rod is nylon material, and effectively expendable weight, also has certain elasticity.Pilot 7, for removing the foreign material on track, prevents that foreign material from damaging vehicle.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications 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.
