Embodiment
As shown in Figure 1 and Figure 2, Stereo tramcar is a kind of novel urban rail transit vehicles, it provides a kind of brand-new urban track traffic pattern.Stereo tramcar is run across on road, and the underframe of its car body is very high, and upper space arranges guest room for carrying, and lower space allows roadlice 21 to pass through, and achieves the multilevel traffic of road.Stereo tramcar is usually across 1 ~ 2 track, and its track is highly identical with road surface 22, can with Car sharing path resource.The track of Stereo tramcar can utilize existing arterial traffic to transform, and cost is low, and the construction period is short.Stereo tramcar by integral car body 1 and four independently EEF bogie 2 form.Car body 1 is monocoque structure, is bearing on the framework 5 of EEF bogie 2 by air bellow 6.EEF bogie 2 is in steel wheel 16 traveling, and two wheels 3 are longitudinally arranged.Wheel adopts the spill tread with bilateral wheel rim (to coordinate with common I-shape rail, as shown in Figure 3), or the worn profile tread of one-sided wheel rim (coordinate with groove-shape rail, as shown in Figure 4), wheel can adopt the elastic wheel of cushion rubber layer.Wheel 3 is connected with framework 5 by axle box 4, arranges bearing in axle box 4, the rolling of wheel is become the translation of vehicle.Framework 5 is arranged air bellow 6, in order to supporting body 1 and mitigation vibration, the setting height(from bottom) of air bellow 6, higher than body gravity height, realizes gravity pendulum structure.The wheel 3 of EEF bogie 2, framework 5 and air bellow 6 slope inwardly formation trapezium structure, and arrange lateral connecting rod 7 between framework 5 and car body 1, rely on gravity to realize horizontal stable.Lateral connecting rod 7 end is ball pivot, can rotate, and lateral connecting rod 7 only retrains the cross motion between EEF bogie 2 and car body 1, and does not retrain the motion in other direction.Horizontal stop 8 is used for limiting cross travel excessive between framework 5 and car body 1.Between framework 5 and car body 1, arrange Z-shaped draw gear 9, as shown in Figure 5, Z-shaped draw gear 9 comprises the first drawing pull bar 17, second drawing pull bar 19, draw beam 18 and towing pin 20.First drawing pull bar 17, draw beam 18, second drawing pull bar 19 are in turn connected to form Z-shaped structure.Draw beam 18 is fixed in the middle part of framework 5 by towing pin 20.Draw beam 18 is connected with towing pin 20 by ball pivot 23, one end of first drawing pull bar 17 is connected with car body 1 by ball pivot 23, the other end of the first drawing pull bar 17 is connected with one end of draw beam 18 by ball pivot 23, one end of second drawing pull bar 19 is connected with the other end of draw beam 18 by ball pivot 23, and the other end of the second drawing pull bar 19 is connected with car body 1 by ball pivot 23.Longitudinal towing mechanism only retrains the longitudinal movement between EEF bogie and car body, and does not retrain the motion in other direction.
The car body of Stereo tramcar is steel or aluminum alloy monocoque structure, is bearing on the framework 5 of EEF bogie 2 by air bellow 6.Vehicle front arranges driver's cab, and middle part is guest room 15.Arrange car door and vehicle window at vehicle body side wall, roof also can arrange vehicle window.The service equipments such as seat, handrail, air-conditioning, heating, broadcast are set in guest room.Equipment compartment is arranged on outside vehicle body bottom frame, for placing electrical equipment.
EEF bogie adopts steel wheel traveling, and two wheels are longitudinally arranged.Owing to being freely in direction of shaking the head between EEF bogie 2 and car body 1, therefore EEF bogie 2 can utilize gravity stiffness to lead.Wheel 3 can adopt the elastic wheel of cushion rubber layer, to reduce wheel-rail noise and to relax wheel-rail impact.
Wheel 3 arranges axletree, and wheel 3 and axletree adopt interference fit, are rigidly connected.Axletree is connected with framework 5 by axle box 4, arranges bearing in axle box 4, the rolling of wheel is become the translation of vehicle.Between axle box 4 and framework 5, can resilient suspension be set, further damped vibration.
Framework 5 is arranged air bellow 6, in order to supporting body 1 with relax vibration, the setting height(from bottom) of air bellow 6 should higher than body gravity height, to realize gravity pendulum structure.Air bellow 6, higher than body gravity, when making car body 1 by curve, can rely on gravitational equilibrium centnifugal force, improve running comfort.
The wheel 3 of EEF bogie 2, framework 5 and air bellow 6 need slope inwardly, and arrange lateral connecting rod 7 between framework 5 and car body 1.Lateral connecting rod 7 constrains the cross motion between EEF bogie 2 and car body 1, and the setting height(from bottom) of lateral connecting rod 7 should, lower than the setting height(from bottom) of air bellow 6, can rely on car body self gravitation to realize vehicle stabilizing in transverse direction like this.Lateral connecting rod 7 end is ball pivot, can rotate, and makes lateral connecting rod 7 only retrain cross motion between EEF bogie 2 and car body 1, and does not retrain the motion in other direction.Such structure makes wheel can rotate around the hinge-point of lateral connecting rod 7, makes wheel adapt to the gauge irregularity of left and right rail, and is relaxed by air bellow 6.Between framework 5 and car body 1, arrange horizontal stop 8, the effect of horizontal stop 8 is cross travels excessive between restriction framework 5 and car body 1, ensures safe in operation.
Between the framework 5 and car body 1 of EEF bogie 2, vertical damper 10 and lateral damper 11 are set, for damped vibration.The ball pivot of lateral connecting rod 7 and Z-shaped draw gear 9 adopts elastic construction as far as possible, impacts to relax and reduces abrasion.
Traction electric machine 12 is arranged on framework 5, is connected with plunging joint by gear case 13 with wheel 3, drives wheel to advance.Each wheel arranges motor, to improve hill climbing ability.Driving can adopt AC induction motor, can arrange architecturally according to the vertical layout in space or longitudinally.Due to EEF bogie individual drive, the drive motor of the EEF bogie that car body two side position is corresponding needs synchronous control technique.
Adopt pantograph, direct current is powered.Pantograph should be arranged on the roof corresponding to EEF bogie, with reduce pantograph connect touch net motion.Main inverter provides electric power for traction system, and subordinate inverter is that body apparatus (air-conditioning, illumination, communication) etc. provides electric power.Main inverter and subordinate inverter hang on car body bottom device cabin.
Brake system comprises electric braking, disc braking and electromagnetic rail brake.Electric braking realizes regenerative brake and rheostatic brake two kinds of forms.Brake disc is arranged on gearbox drive axle, and brake clamp is installed architecturally, realizes disc braking.Disc braking can use pressurized air or fluid power as power.Magnetic rail brake device is arranged on frame underneath, to meet the demand of braking deceleration.
Stereo tramcar can single operation, also can organize into groups operation in column.When organizing into groups in column, connected by hitch 25 and hang, can establish by platform 24 between adjacent car body, be convenient to passenger and flow between each joint car, as shown in Figure 6.
