Embodiment
Like Fig. 1, shown in Figure 2, three-dimensional tramway train is a kind of later-model urban rail transit vehicles, and it provides a kind of brand new urban track traffic pattern.Three-dimensional tramway train is across moving on road, and the underframe of its car body is very high, and upper space is provided with the guest room and is used for carrying, and lower space allows roadlice 21 to pass through, and has realized the multilevel traffic of road.Three-dimensional tramway train is usually across 1～2 track, and its track is highly identical with road surface 22, can share path resource with automobile.The track existing arterial traffic transformation capable of using of three-dimensional tramway train, cost is low, and the construction period is short.Three-dimensional tramway train by integral car body 1 and four independently traveling portion 2 form.Car body 1 is a monocoque structure, is bearing in through air bellow 6 on the framework 5 of traveling portion 2.Traveling portion 2 is in steel wheel 16 travelings, and two wheels 3 are vertically arranged.Wheel adopts the spill tread (cooperating with common I-shape rail, as shown in Figure 3) with bilateral wheel rim, or the worn profile tread of one-sided wheel rim (cooperating with the grooved rail, as shown in Figure 4), and wheel can adopt the elastic wheel of cushion rubber layer.Wheel 3 is connected with framework 5 through axle box 4, in the axle box 4 bearing is set, and the rolling of wheel is become the translation of vehicle.Air bellow 6 is set on the framework 5, vibrates with relaxing in order to supporting body 1, the setting height(from bottom) of air bellow 6 is higher than the body gravity height, realizes the gravity pendulum structure.The wheel 3 of traveling portion 2, framework 5 and the air bellow 6 formation trapezium structure that slopes inwardly, and between framework 5 and car body 1, lateral connecting rod 7 is set, it is horizontal stable to rely on gravity to realize.Lateral connecting rod 7 ends are ball pivot, can rotate, and lateral connecting rod 7 only retrains the cross motion between traveling portion 2 and the car body 1, and do not retrain the motion of other direction.Laterally stop 8 is used for limiting excessive cross travel between framework 5 and the car body 1.Z-shaped draw gear 9 is set between framework 5 and car body 1, and as shown in Figure 5, Z-shaped draw gear 9 comprises 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 on framework 5 middle parts through towing pin 20.Draw beam 18 is connected with towing pin 20 through ball pivot 23; One end of first drawing pull bar 17 is connected with car body 1 through ball pivot 23; The other end of first drawing pull bar 17 is connected with an end of draw beam 18 through ball pivot 23; One end of second drawing pull bar 19 is connected with the other end of draw beam 18 through ball pivot 23, and the other end of second drawing pull bar 19 is connected with car body 1 through ball pivot 23.Longitudinal towing mechanism only retrains the longitudinal movement between traveling portion and the car body, and does not retrain the motion of other direction.
The car body of three-dimensional tramway train is steel or aluminum alloy monocoque structure, is bearing in through air bellow 6 on the framework 5 of traveling portion 2.Vehicle front is provided with driver's cab, and the middle part is guest room 15.At the car body side wall car door and vehicle window are set, roof also can be provided with vehicle window.Service equipments such as seat, handrail, air-conditioning, heating, broadcasting are set in the guest room.Equipment compartment is arranged on the car body underframe outside, is used to place electrical equipment.
Traveling portion adopts the steel wheel traveling, and two wheels are vertically arranged.Owing to be freely in the direction of shaking the head between traveling portion 2 and the car body 1, so traveling portion 2 gravity stiffness capable of using lead.Wheel 3 can adopt the elastic wheel of cushion rubber layer, to reduce wheel-rail noise and to relax wheel-rail impact.
On the wheel 3 axletree is set, wheel 3 adopts interference fit, is rigidly connected with axletree.Axletree is connected with framework 5 through axle box 4, in the axle box 4 bearing is set, and the rolling of wheel is become the translation of vehicle.Between axle box 4 and the framework 5 resilient suspension can be set, further damped vibration.
The wheel 3 of traveling portion 2, framework 5 and air bellow 6 need slope inwardly, and between framework 5 and car body 1, lateral connecting rod 7 are set.Lateral connecting rod 7 has retrained the cross motion between traveling portion 2 and the car body 1, and the setting height(from bottom) of lateral connecting rod 7 should be lower than the setting height(from bottom) of air bellow 6, can rely on the car body self gravitation to realize that vehicle is in horizontal stabilizing like this.Lateral connecting rod 7 ends are ball pivot, can rotate, and make lateral connecting rod 7 only retrain the cross motion between traveling portion 2 and the car body 1, and do not retrain the motion of other direction.Such structure makes wheel to rotate around the hinge-point of lateral connecting rod 7, makes wheel adapt to the gauge irregularity of left and right rail, and obtains relaxing through air bellow 6.Horizontal stop 8 is set between framework 5 and car body 1, and laterally the effect of stop 8 is excessive cross travels between restriction framework 5 and the car body 1, guarantees safe in operation.
Traction electric machine 12 is installed on the framework 5, is connected with wheel 3 with plunging joint through gear case 13, and drive wheels is advanced.Motor all is set, to improve hill climbing ability on each wheel.Driving can be adopted AC induction motor, can or vertically be arranged on the framework according to the vertical layout in space.Because traveling portion individual drive, the drive motor of the cooresponding traveling of car body two side positions portion needs synchronous control technique.
Adopt pantograph, direct current receives.The receptor site bow should be arranged on the pairing roof of traveling portion, to reduce the motion that pantograph connects and touches net.Main inverter is that traction system provides electric power, 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 is realized regenerative brake and two kinds of forms of rheostatic brake.Brake disc is installed on the gearbox drive axle, and the braking clamp is installed on the framework, realizes disc braking.Disc braking can use pressurized air or fluid power as power.Magnetic rail brake device is installed in frame underneath, to satisfy the demand of braking deceleration.
Three-dimensional tramway train can single operation, also can be organized into the row operation.When being organized into row, connect extension, can establish through platform 24 between the adjacent car body, be convenient to the passenger and between each joint car, flow through hitch 25, as shown in Figure 6.
