6 energy-conservation mechanical analyses
6.1 tire operation force analysis figure is referring to Fig. 3.
6.2 when engine torque acts on tire, surface of tyre is produced propulsive effort F1, as can be known by the friction drag definition, this moment, tire and ground produced friction drag F2, as shown in Figure 1, between a D tire and ground, be parallel motion, its frictional property is a cliding friction.The size of friction drag F2 depends on weight of object, area of contact and object friction coefficient.When F1=F2, state of motion of vehicle is constant, and static maintenance is static, and motion keeps kinematic velocity constant.When drawing force F3 acts on a some A, frictional property is a friction of rolling between tire and ground, its friction coefficient size depends on factors such as the elasticity, rigidity of tire, here get 1/10 (see annotate 2) of coefficient of sliding resistance. when drawing force F3 acts on a some A, it is constant to keep state of motion of vehicle, and drawing force F3 only is 1/10 of propulsive effort F1.
Annotate:
1. the size of moving force of sliding friction is more smaller than maximum static friction force fmax.Can think in the common calculating that maximum static friction force equals force of sliding friction.[5] 43 pages
2. coefficient of rolling friction y span is that 0.1cm is to 0.2cm.Consider that by the least favorable situation by 0.2cm, the wheel radius r is got 20cm, then y/r=0.01. does not roll when F3＜=0.01N (N is a normal reaction) tire.As F1＜=F2=0.1N (0.1 is the moving coefficient of sliding resistance of tire and road), then F3/F1=1/10.[4] 62 pages
6.3 common conclusions;
By power P=FV, do not considering under energy conversion efficiency and air resistance the situation the vehicle operating influence, the straight line electric traction, when drawing force F3 acts on a some A, power demand P3=F3*V is about as much as driving engine, comprise combustion engine, hydrogen engine, electrical motor, solar power etc. with power transfer be tire propulsive effort F1 act on a D power demand P1=F1*V 1/10.
That is: P3=1/10*P1 even lower because of only doing the engineering qualitative analysis, sees that from the mechanics angle linear electric machine traction drives energy-conservation mechanics principle than driving engine-tire, sees also pertinent data in detail here.
7 underground other characteristics of power supply linear electric machine traction over-the-road transportation:

8.2 prolong road, tire service life, reduce roadupkeep expense and vehicle tyre expense.
When conventional truck was travelled, vehicle acceleration, walking and brake deceleration were ordered about in roller tire and frictional ground force effect, make the major cause that causes road and tire wear.Heavy-duty vehicle particularly, friction force is big, and is even more serious to road and tire wear.When vehicle is dragged when travelling by the underground linear electric motors of underground power supply, the power of powered vehicle walking and brake be rail vehicle just/electromagnetic force between time limit, tire and ground-surface only be friction of rolling, do not need engine power is converted to frictional force drives vehicle to run between tire and ground, thereby reduce loss, reduce roadupkeep expense and vehicle tyre expense road and tire.With the tire is example, 6,000 thousand ten thousand vehicles in the whole nation, average year operation 20,000 kilometer, 4 tires of 100,000 kilometers replacings in per 5 years, about 4000 yuan of average cost is amounted to annual 4000/5=800 unit. as increase the service life one times, then annual average cost 4000/10=400 unit, the annual cost of tires 400*60 that saves in the whole nation, 000,000=24,000,000,000 yuan (24,000,000,000 yuan).
