Description
Technical field
The utility model relates to the vehicular traffic field, is specifically related to a kind of Wheeling System of on-road vehicle.
Background technology
The wheel of vehicular traffic is divided into two of flower wheel and drive wheels, take automobile as example, in " automobile theory ", the sport dynamics characteristic of these two kinds of wheels is done to penetrating the discussion:
Drive wheel is to rely on the torque movements be passed on its circumference, and really acting on and driving the power of automobile on drive wheel is the tangential antagonistic force F in ground
x, its numerical value is propulsive effort F
tdeduct the rolling resistance F on drive wheel
f, the propulsive effort equation of equilibrium is:
F
x?=?F
t?-?F
f
The characteristics of this formula are that drive wheel also has rolling resistance F
f, this rolling resistance is born load by drive wheel and is produced, and the propulsive effort of drive wheel is the tangential antagonistic force F in ground
xwith drive wheel rolling resistance F
fsum:
F
t?=?F
x?﹢?F
f?
Flower wheel is to rely on the thrust that acts on its center to move.The rolling resistance F of flower wheel
fequal the ratio of coefficient of rolling resistance f(thrust and wheel weight) with the product of wheel weight W, the rolling resistance formula is:
F
f?=?W?f
According to the difference of these two kinds of wheel movement mechanical characteristics, we can also be divided into two classes by the on-road vehicle driving mode, i.e. drive wheel driving mode vehicle class and flower wheel driving mode vehicle class.For example, the power car that the drive wheels such as automobile, motor bike, battery-driven car, bicycle are also born load belongs to drive wheel driving mode vehicle class; The vehicle that the flower wheels such as rickshaw, animal-drawn vehicle, trailer are born whole load (or drive wheel is not born load) belongs to flower wheel driving mode vehicle class.This is the driving mode of two kinds of different essence, and the key distinction is whether drive wheel bears car load, the difference of required propulsive effort while being Vehicle Driving Cycle, and the vehicular drive condition formula has convincingly demonstrated the difference of these two kinds of different driving modes.
The drive condition of Vehicle Driving Cycle (necessary condition) is F
t>=F
f+ F
w+ F
i, according to the understanding of flower wheel and drive wheel motion characteristics, it is the description to flower wheel driving mode vehicle that this formula more is close to.Because, for drive wheel driving mode vehicle, rolling resistance Ff should be contained the rolling resistance F of its flower wheel
f1rolling resistance F with drive wheel
f2, now rolling resistance is:
F
f?=?F
f1?+?F
f2
And propulsive effort also should add the tangential antagonistic force F in ground while calculating
x.So, vehicle take the drive condition of drive wheel driving mode while travelling as:
F
t?=F
x?+?F
f1+?F
f2?+?F
w?+?F
i
(in formula: F
tfor propulsive effort, F
wfor air resistance, F
ifor grade resistance).Therefore, the different required propulsive effort of vehicle of two class car travel modes is also different.
Prior art was not carried out analytical investigation to car travel mode, had lost the chance that significantly improves Vehicle Driving Cycle efficiency.The required propulsive effort of vehicle flower wheel driving mode (propelling thrust) is far smaller than the drive wheel driving mode, and this advantageous characteristic is to confirm by illustration (illustration puts aside the conditions such as resistance due to acceleration, air resistance, grade resistance).
Illustration one:
If Electrical Bicycle total mass (containing load) is 1470N for 150Kg, gravity; Rolling resistance of wheel coefficient f
1be 0.03; Calculate the rolling resistance F of vehicle during the flower wheel driving mode according to the rolling resistance formula
ffor 44.1N; For the drive wheel driving mode, if the load of 60 ﹪ on drive wheel, the coefficient of rolling resistance f of drive wheel
23 times (getting 0.09) of flower wheel, the rolling resistance F of vehicle during conventional drive wheel driving mode
ffor 97.02N(F
f=F
f1+ F
f2, F
f1=0.4W
f1, F
f2=0.6W
f2), overcome the required propulsive effort of rolling resistance and be 2.2 times of flower wheel driving mode vehicle, the propulsive effort of increase is 52.92N(54.54 ﹪).
Illustration two:
The roadlice total mass is that 2000Kg, gravity are 19600N; Rolling resistance of wheel coefficient f is 0.02; Calculate the rolling resistance F of vehicle when the flower wheel driving mode travels according to the rolling resistance formula
ffor 392N; For the drive wheel motoring condition, if the load of 65 ﹪ on drive wheel, the coefficient of rolling resistance of drive wheel is 2.5 times (getting 0.05) of flower wheel, when conventional drive wheel driving mode travels, the rolling resistance of vehicle is that 774.2N(is F
f1with F
f2two values and), overcome the required propulsive effort of rolling resistance and be 1.975 times of flower wheel driving mode vehicle, the propulsive effort of increase is 382.2N(49.37 ﹪).
Above illustration fully confirms: required propulsive effort when the driving wheel of vehicle driving mode travels (overcoming the propulsive effort of rolling resistance) is more than 2 times of flower wheel driving mode; Vehicle travels with the drive wheel driving mode, and its efficiency increases and reduces with drive wheel coefficient of rolling resistance, wheel weight.
The immediate cause that causes this result, be that conventional drive wheel has load concurrently, drives dual-use function, is doubled and redoubled to the coefficient of rolling resistance that makes drive wheel.
" automobile theory " research is thought: for the tire under the driving situation, effect has driving torque, and tyre surface quite has slip to a certain degree for ground, the waste of power while having increased tire rolling; Under than large driving force coefficient operating mode, the rolling resistance of drive wheel system increases sharply with the increase of the propulsive effort coefficient ratio of radial weight (propulsive effort with).At the propulsive effort coefficient, be 0.8 o'clock, the Radial Tire Rolling Resistance coefficient increases twice, and diagonal tyre increases more than three times.
From surface analysis can learn, conventional drive wheel has load concurrently, drives dual-use function, its functional structure is full of contradictions, these contradictions are entangled with and are mainly reflected in radius of wheel size Selection, tire surface friction intensity selection aspect:
1) according to the characteristic of wheel movement mechanics, suitable little (propulsive effort is large) flower wheel radius of driving wheel of vehicle radius is (rolling resistance is little) greatly, and the overlapping conventional drive of function is taken turns its radius value and is kept in contradictions;
2), according to the material surface mechanics principle, the friction of driving wheel of vehicle surface of tyre is (adhesive ability is large) free-rolling tyre surface friction suitable little (rolling resistance is little) greatly, the conventional drive wheel that function is overlapping, and the tire surface property is got and is contradicted;
In sum, automobile driving wheel driving mode comparison flower wheel driving mode need to increase the above propulsive effort of 50 ﹪, has serious efficiency drawback, causes very serious energy dissipation problem.
