In order to prevent wheel tyre from contacting to earth, the distance between the core axis of wheel hub 12 and ground are more than the radius of wheel,
So that wheel has gap when rotating with ground, also space is provided for tire installation.
In order that student is it will be appreciated that the operation principle of differential mechanism 1, the present embodiment devise straight-line travelling and turning driving
Two states, allow the situation of change that the internal gear of differential mechanism 1 operates in the case of two kinds of observation of students, and then understand that differential mechanism 1 is
How differential is realized.
Fig. 4 is the structural representation of differential mechanism 1 provided by the utility model.Differential mechanism 1 is can to adjust turning for left and right wheels
Speed difference, left and right wheels are enable to be rotated with different rotating speeds.Differential mechanism 1 is mainly by left half axle gear 101, right axle shaft gear 102, two
Planetary gear 103 and differential casing 104 form.Left half axle gear 101, right axle shaft gear 102 and two planetary gears 103 are all
In the shell of differential mechanism 1, differential casing 104 is connected to power transmission shaft 7, and itself will also rotate, in motion its rotation direction with
Vehicle wheel rotation direction is identical.The design requirement of differential mechanism 1 meets：(rotating speed of left half axle gear 101)+(102 turns of right axle shaft gear
Speed)=2 (rotating speed of differential casing 104).
When car straight-line travelling, the resistance of the right and left driving wheel is roughly the same, and the power exported from power source 5 passes first
It is delivered on differential casing 104, makes differential casing 104 start to rotate, and drive planetary gear shaft to rotate, makes planetary gear
103 revolve round the sun around axle shaft gear axis, at the same planetary gear 103 around axle shaft gear axis revolution by left half axle gear 101 and the right side
Axle shaft gear 102 clamps, because the resistance of the right and left driving wheel is roughly the same, the planetary gear 103 in differential casing 104
And then the revolution of differential casing 104 will not produce rotation simultaneously, and two planetary gears 103 are engaged two axle shaft gears with identical
Speed rotate, drive left half axle gear 101 and right axle shaft gear 102 to export power to left half axle 201 and right axle shaft 202, enter
One step is transmitted to left and right sides wheel.Therefore, when linear rows are driven, left side wheel rotating speed (i.e. the rotating speed of the left half axle gear 101)=right side
The rotating speed of side vehicle wheel rotational speed (i.e. the rotating speed of right axle shaft gear 102)=differential casing 104.
When car turning driving, because the radius of turn of outboard wheels is greater than the radius of turn of inboard wheel, outside car
Wheel is longer than the distance that inboard wheel is passed by, and comparatively, the resistance increase of inside turn traveling, inboard wheel rotating speed is less than poor
The fast rotating speed of device housing 104, there occurs rotation, opposite side vehicle wheel rotational speed on the basis of original revolution to rise naturally for planetary gear 103
Height, higher than the rotating speed of differential casing 104, left and right wheelses is rolled with different rotating speeds, ensure that both sides driving moment makees pure rolling
Motion.
Simulate the presentation process of car straight-line travelling and turning driving state：
When opening control button 10, motor is started working after powered up, and speed changer 6 is in neutral gear position, stirs and changes
Block handle reaches power by power transmission shaft 7 by 1 grade of travelling gear the input shaft of differential mechanism 1, if now not to 1 file location
Braking is (during simulating vehicle straight-line travelling), you can the operating condition of the observation internal gear of differential mechanism 1.When brake pedal 301
Afterwards, when being braked to left half axle 201 (when simulating vehicle is turned), the operating condition of the internal gear of differential mechanism 1 is observed again, is led to
Cross both contrasts, you can analysis and summary goes out the operation principle of differential mechanism 1.
In order that student it will be appreciated that the transmission principle of speed changer 6, the present embodiment devise shift process, enables student
The engagement of the internal gear group of speed changer 6 and situation about separating can be clearly seen, and then understand the transmission principle of speed changer 6.
Speed changer 6 is a kind of speed change gear, for changing rotating speed and the torque that engine is passed on driving wheel, is risen in situ
Under the various operating modes such as step, climbing, turning, acceleration, automobile is set to obtain different tractive force and speed, while be operated in engine
In condition range advantageously.
Simulate the presentation process of gearshift：
The speed changer 6 of the present embodiment divides for 5 grades, and when opening control button 10, motor is started working after powered up, electricity
Power is reached speed changer 6 by motivation, when gear level 8 pulls out a lattice to the left, when stirring further along, 1,2 grade of synchronizer to the left with 1 grade
Gear engages, then speed changer 6 has been linked into 1 grade, and power reaches 1 shelves gear, and power is reached output extremely by 1 shelves gear by jackshaft
Power transmission shaft 7；When gear level 8 pulls out a lattice to the left, then stirs backward, 1,2 grade of synchronizer engages to the right with 2 shelves gears, then becomes
Fast device 6 has been linked into 2 grades, and power reaches 2 shelves gears, and power is reached output to power transmission shaft 7 by 2 shelves gears by jackshaft；When changing
When pin 8 is stirred forward, 3,4 grades of synchronizers engage with 3 shelves gears to the left, then speed changer 6 has been linked into 3 grades；When gear level 8 backward
When stirring, 3,4 grades of synchronizers engage to the right with 4 shelves gears, then speed changer 6 has been linked into 4 grades；Gear level 8 is pulled out into the right a lattice
And when stirring forward, then speed changer 6 has been linked into 5 grades.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
