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 power truck for 100% low floor vehicle, comprise framework 20 and two wheel shafts 17, described framework 20 comprises the recessed and curb girder be parallel to each other in two middle parts and to be connected between the recessed portion in the middle part of two curb girders and the crossbeam be parallel to each other.Curb girder is the bow-shaped structural of weathering steel assembly welding, 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 are from inside to outside connected axle box 16, elastic wheel 6 and brake disc 21 successively and are arranged on bottom curb girder by the single stage suspension mount pad of axle box 16 front and back end and single stage suspension 23.Wheel shaft 17 diameter is little, and therefore adopt solid axle structure, elastic wheel 6 then adopts V-type elastic wheel, can vibration-absorbing denoising.Axle box 16 top is also provided with safe stop, ensures that vehicle can also safe operation after single stage suspension et out of order.
Described wheel shaft 17 end connecting earthing device 2.Described earth system 2, for facilitating the conduction of electric current, avoids electric current to cause damage by the bearing between wheel shaft 17 and elastic wheel 6 to it.
Electromagnetic rail brake device 3 is connected between the axle box 16 of described two wheel shafts 17 with end.Described electromagnetic rail brake device 3 according to the abrasion adjustment height of elastic wheel 6, can be mainly used in the operating modes such as emergency brake of vehicle.
Top, described curb girder one end fixed electrical machinery 24, motor 24 export through side rail outer reductor 13 slow down after again by elastic clutch 18 by transmission of power to elastic wheel 6, sandbox 9 is established at curb girder other end top, sandbox 9 is equipped with Air compressor 1, in the middle part of curb girder, inside recessed portion, is fixedly installed horizontal backstop 11.Same side detachable connection drawing pull bar 22 respectively of described two curb girders, different end arranges transverse damper 8 and brake clamp 27 respectively.Because motor 24, reductor 13 are arranged on framework 20, owing to there is amount of deflection change, not on the same axis, the amount of deflection of elastic clutch 18 just can meet the change that is amount of deflection for the mouth of reductor 13 and axle centerline, ensures that reductor 13 failure-free transmits torque on wheel shaft 17.Described horizontal backstop 11 and transverse damper 8 are with the center of framework 20 for center of symmetry skew symmetry is arranged, horizontal 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.
It is outer and arrange secondary suspension mount pad in end that curb girder is stretched out at described two crossbeam two ends jointly, and this secondary suspension mount pad arranges secondary suspension 5, vertical backstop 12 and vertical bumper 15.Secondary suspension 5 is made up of height circle spring and upper and lower two pieces of rubber pads thereof, and this structure can ensure vertical stiffness and lateral stiffness, meets dynamic (dynamical) requirement.Secondary suspension 5 is arranged on side rail outer, adds 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 are with the center of framework 20 for center of symmetry skew symmetry is arranged, 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, is in clamped condition, by brake release under the control of release of brake unit 10 under the control of brake fluid pressure unit 14.
The corresponding elastic wheel 6 of side rail outer of described framework 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 absorption and deadening effect to noise fricative between wheel track.
Described sandbox 9 arranges sand pipe, and 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, effectively prevent braking time elastic wheel 6 locking and start time elastic wheel 6 skid.
Secondary suspension 5 on described secondary suspension mount pad has two groups, is provided with lifting appliance 4 between two groups.
Described axle box 16 end winding support is provided with pilot 7.This pilot 7 is made up of mount pad and troubleshooting rod, and troubleshooting rod is nylon material, can effective expendable weight, also has certain elasticity.Pilot 7, for removing the foreign material on track, prevents 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 amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
