The utility model is applied in the variable traffic system of track width, sets forth the utility model below further and how to be applied in this traffic system.
See shown in Fig. 9-12, have track 6 and vehicle 7, track 6 can be set up in parallel many groups, and vehicle 7 is along track 6 unidirectional operation of correspondence.Track 6 has two rails, and every bar rail top is all formed with a recessed circular arc guide groove 61, and this guide groove 61 runs along this guide groove as the guiding operation cell body limiting wheel group 2 of rail.Vehicle 7 adopts the electric four-wheeled guideway vehicle of self-powered, and when it travels, wheel 2 just in time falls in the guide groove 61 on described rail top, is formed the stability force of side direction by guide groove 61 pairs of wheel groups 2.The bottom surface of described guide groove 61 inside face is provided with friction lining, and the wheel group 2 that can be vehicle 7 by friction lining provides advances or brake required friction force.
The wheelspan of vehicle 7 can realize change, and under normal motoring condition, the wheelspan of vehicle is L, and when needs modified line, the wheelspan of vehicle will fade to L1 by L, wherein L>L1.
During normal vehicle operation, the wheel group 2 of vehicle 7 is limited by the groove 61 of track 6 advances along track 6, and the width of track 6 and the wheelspan of vehicle 7 remain unchanged, and wheelspan and track width are L.
The traffic circulation state realized in this example is: some vehicles 7 travel on path 1, and will enter modified line hinge 8.Bifurcation mouth 64 place before modified line hinge 8 shunts by all vehicles 2, realizes continuing to travel and modified line.Namely these vehicles travelled comprise: the vehicle 71 of invariant line and the modified line vehicle 72 of needs.Track 6 will diverge by bifurcation mouth 64, and form craspedodrome track 62 and modified line track 63, the vehicle 71 of invariant line continues to advance along craspedodrome track 62, and the vehicle 72 needing modified line to stop enters modified line track 63 and carries out the operation such as modified line, parking.
Described craspedodrome track 62 adopts with modified line track 63 and distributes up and down, and by craspedodrome track 62 and modified line track 63 bifurcation mouth 64, the track width of craspedodrome track 62 remains unchanged, and invariant line vehicle 71 wheelspan L remains unchanged, and continues to advance along craspedodrome track 62; By craspedodrome track 62 and modified line track 63 bifurcation mouth 64, the track width of modified line track 63 narrows gradually, the track of modified line simultaneously 63 will sink, modified line vehicle 72 is when entering modified line track 63, and its wheelspan L diminishes simultaneously, with the width adequate of modified line track 63, and start to sink along modified line track 63 simultaneously, until modified line track 63 width and modified line vehicle 72 wheelspan all become L1, now, vehicle has achieved staggered shunting.Invariant line vehicle 71 continues to travel along craspedodrome track 62, and modified line vehicle 72 realizes modified line along modified line track 63.The modified line vehicle 72 entering modified line track 63 can stop on modified line track 63, realizes vehicle and pulls in, the object of passenger getting on/off.
Shown in Figure 2, when vehicle needs to cross modified line, craspedodrome track 62 and modified line track 63 will cross at river conjunction 65, and invariant line vehicle 71 continues to advance along craspedodrome track 62, until enter in the track 6 after river conjunction 65, the width of craspedodrome track 62 and the wheelspan L of vehicle do not change; Modified line track 63 is in the process be combined with river conjunction 65 place, and its track width broadening gradually, changes to L by L1.The track of modified line simultaneously 63 starts to raise, to cross with craspedodrome track 62, its wheelspan of modified line vehicle 72 of advancing along modified line track 62 becomes large simultaneously, changes to L by L2, and start to raise, the distribution along modified line track 63 is carried out until cross at river conjunction 65 place with craspedodrome track 62. simultaneously
For the ease of controlling, modified line hinge 8 need be set in bifurcation mouth 64 and river conjunction 65 place.Realize interlocking up and down at modified line hinge 8 place's craspedodrome track 62 and modified line track 63.Modified line hinge 8 is herein equivalent to overpass in current highway communication or platform, and vehicle realizes the modified line of diverging, crossing in modified line hinge 8.
Certainly, the foregoing is only specific embodiment of the utility model, be not limit the utility model practical range, all equivalences done according to structure, feature and principle described in the utility model claim change or modify, and all should be included in the utility model claim.
