Detailed description of the invention
1. passenger compartment is independent and dynamic
Passenger compartment individually can customize according to passenger's volume size, weight size, is then placed in bus compartment baseplane
On.Pulley lateral symmetry distribution below passenger compartment, pulley quantity according to passenger's volume size, weight size and determine.Passenger compartment is led to
Cross the insulated connecting piece connected between rectangle metallic conductor loop ABCD to be connected (see figure with rectangle metallic conductor loop ABCD
Shown in 1 and Fig. 3).Metallic conductor loop is also to be symmetric centered by passenger compartment.
The bus compartment baseplane of carrying passenger compartment is embedded with two rail plates, for sliding of passenger compartment pulley, passenger compartment
After being placed in bus compartment baseplane, initial rest state can keep passenger compartment static by the locking of pulley electric lock buckle device.
Unlike material such as rubber and metal etc., additionally surface is selected at slide on rails frictional force, pulley and guide rail in order to increase passenger compartment
Roughness can be increased.
2. the mechanical kinetic energy under inertia promotes passenger compartment slip cutting magnetic line in magnetic field, the magnetic field Ampere force of generation and visitor
The passenger compartment slided is done negative work by bonding force that railway carriage or compartment force of sliding friction is formed together the most continuously, and continuous consumption reduces passenger compartment and is used to
Property mechanical kinetic energy is until it is zero
In the front and rear portions of bus compartment, there are same area area and two of identical constant uniform magnetic field intensity B respectively
Uniform magnetic field that is first magnetic field and the second magnetic field (as shown in Figure 3), and be all symmetric centered by passenger compartment.First magnetic field
Region and the second field region can flow to contrary two large-sized DC coil windings by DC current respectively and realize, thus

Use the most ripe bus to travel the technology that charges a battery, front and back two group storage battery provide straight the most continuously
Stream electric current.From top to bottom, the magnetic line of force direction in the second magnetic field is from lower to upper in the magnetic line of force direction in the first magnetic field.The following is public transport
The analysis of car different conditions:
1) (engine start, car does not travels) during bus original state
When bus is in original state (engine start, car does not travels), the electric lock buckle device pine of passenger compartment pulley
Opening, the most constant uniform magnetic field intensity is all that two magnetic fields of B load simultaneously, owing to the forward and backward part in metallic conductor loop is
One identical with the area of the second field region (being the most all the 1/2 of the first and second field region areas) (as shown in Figure 3).Institute
With according to Lenz's law and Faraday law of electromagnetic induction, in metallic conductor loop, the change due to magnetic flux will produce sensing
Electromotive force, and the two induction electromotive force (as shown in Figure 5) in opposite direction equal in magnitude, so rectangle metallic conductor loop
ABCD does not have faradic current produce, will not be by Ampere force effect, thus now passenger compartment keeps resting state in magnetic field.
2) unexpected deceleration regime during bus travels
Assume that bus is turned left direction running, acceleration or deceleration suddenly in bus travels, due to inertia passenger compartment and
The rectangle metallic conductor loop ABCD connected, will be slided by the pulley of passenger compartment self, it is assumed that vehicle slows down suddenly, passenger compartment
And the rectangle metallic conductor loop ABCD connected is owing to inertia is by gliding motility to the left (as shown in Figure 4), and lead to respectively
Cross two field regions that before and after stationary magnetic field intensity is all B, make metallic conductor AD and BC cutting magnetic line produce dynamic raw electronic
Gesture, and in metallic conductor loop produce faradic current (shown in Fig. 4 and Fig. 6), flow through faradic metallic conductor AD and
BC can be subject to again the Ampere force F1 the most to the right in opposite direction with loading space inertia motion and F2 effect (see Fig. 4 institute in magnetic field
Show), the bonding force that conjunction Ampere force F (F1+F2) and force of sliding friction (see figure 1) are formed together is continuously to the passenger compartment slided
Do negative work, continuous consumption passenger compartment and the inertia mechanical kinetic energy of rectangle metallic conductor loop ABCD that connected thereof until being zero,
Reach inertia balance.
Have according to Faraday law of electromagnetic induction and calculate as follows:
E=BLV------is 1.
E------motional electromotive force；
B------magnetic field magnetic induction；
L--------cutting magnetic line conductor length；
V--------cutting magnetic line speed；
Faradic current in I--------conductor circuit；
R--------conductor circuit resistance；
In magnetic field, Ampere force F=BIL-------is 3.
According to formula 2. with formula 3., Ampere force in magnetic fieldAnd the direction of Ampere force is according to a left side
Hands theorem determines.
According to when slowing down suddenly in travelling with fooled hypothesis vehicle, due to inertia, rectangle metallic conductor loop ABCD's
Metallic conductor AD and BC is by cutting magnetic line, and now motional electromotive force and faradic current size are calculated as follows:
According to formula 1., owing to B is identical, V is identical, LAD=LBC=L, so E1=E2, so total electromotive force E=2BLV,
In rectangle metallic conductor loop ABCD, faradic current is just:According to formula 4., Ampere force F1=Ampere force in Fig. 4
F2, so closing Ampere forceNow according to left hand theorem, Ampere force F1 and F2
Turn right (as shown in Figure 4) in direction, so turning right in the direction closing Ampere force F.During inertia balance, close Ampere force F (F1+F2) with
And the passenger compartment slided is done negative work, continuous consumption passenger compartment by bonding force that force of sliding friction μm g (see figure 1) is formed together continuously
And the inertia mechanical kinetic energy of the rectangle metallic conductor loop ABCD connected is until being zero.In this inertia balance process
In, owing to doing negative work continuously, so cutting magnetic line speed consecutive variations, close Ampere force F also consecutive variations.
According to kinetic energy theorem: bonding force is equal to the change i.e. F1 of object kinetic energy to object work done
F-----bonding force；
The displacement occurred on l-----bonding force direction；
Angle between direction and the direction of displacement of θ-------bonding force；
V1-----object of which movement initial velocity；
V2-----object of which movement terminates speed；
Suddenly slow down in bus travels, during inertia balance, close Ampere force F (F1+F2) and sliding friction
The passenger compartment slided is negative work, passenger compartment and the rectangle metallic conductor loop ABCD connected thereof and is cut magnetic by power μm g together continuously
Line of force speed consecutive variations, 2. understanding according to formula and closing Ampere force F is variable force, although force of sliding friction μm g is fixing, but it
Formed together with closing Ampere force F is that continuous variable force is doing negative work, according to formula 5., owing to closing Ampere force and cutting magnetic line speed
Degree is linear relationship, so the displacement that bonding force and passenger compartment are slided also is linear changing relation, so variable force does negative work and is equal to
Mean force does negative work, and during inertia balance, V2 is 0 (i.e. through inertia balance, passenger compartment is finally stopped slip), and V1 is exactly public
In handing over car to travel when slowing down suddenly, passenger compartment and the rectangle metallic conductor loop ABCD that connected thereof due to inertia start to slide time
Initial velocity (that is initial velocity of cutting magnetic line), so in sum according to formula 6., have a below equation:
3) during bus at the uniform velocity travels
When bus remains a constant speed in traveling, owing to not having inertia to occur, thus metallic conductor AD and BC does not moves cutting
The magnetic line of force, so not having motional electromotive force, produces hence without faradic current, so will not be by Ampere force effect, now visitor
Railway carriage or compartment keeps resting state in magnetic field.
4) stop during bus travels
Bus stops (now electromotor does not closes), such as above-mentioned 2 in travelling) as described in, passenger compartment is by inertia balance technology also
Reaching inertia balance simultaneously, now do not close due to electromotor, magnetic field intensity B of two field regions still keeps stress state,
But inertia balance has been reached due to passenger compartment, metallic conductor AD and BC non-motion cutting magnetic line, so there is no motional electromotive force, because of
And do not have faradic current to produce, and will not be by Ampere force effect, if now on-board and off-board door is opened, then passenger compartment pulley passes through electric lock
Buckle device is locked, and keeps passenger compartment to remain static.Once on-board and off-board door Close All, then passenger compartment pulley passes through electric lock spiral-lock
Put and unclamp.
5) bus stops engine stop
When bus stops engine stop, added loaded magnetic field stops loading immediately, and passenger compartment pulley passes through electric lock spiral-lock
Put locking, keep passenger compartment to remain static.
