6, pulley assembly 50 is divided into four groups, it is respectively first pulley 51 that places the centrifugal wheel lower right corner (being the working direction below), second pulley 52 in the lower left corner, the 3rd pulley 53 in the upper left corner, the 4th pulley 54 in the upper right corner, the size shape of each pulley is identical, it all is circular sheave, be that columned pulley midway location has pulley groove 55, this pulley groove 55 matches with the right-angled triangle guide rail 13 of slip drum 10 convexes and can roll relatively, these pulley groove 55 grooves triangular in shape, each organizes the axle of being furnished with bearing respectively and matching with it in the pulley, each axial length is short different, wherein the sheave shaft 511 of the sheave shaft 511 of first pulley and the 4th pulley stretches out the supporting plate outside and is connected close-fitting with car chassis crossbeam or other car beam, while is in conjunction with the connection situation of positioning component 70, trammel beam 81 anchor shafts also with car chassis crossbeam close-fitting, the gravity of automobile acts on first pulley 51 fully as can be seen, and first pulley 51 must place the place ahead of wheel and ground contact point.

7, simultaneously referring to Fig. 7, balanced component 80 comprises trammel beam 81,83 3 parts of balance wheel 82 and spring assembly, balance wheel 82 also is circular sheave, the centre has race and the right-angled triangle guide rail 13 of slip drum 10 convexes and matches and can roll relatively, trammel beam 81 is down " fourth " font, balance wheel 82 is fixed on the balancing axle 84 on right side of trammel beam 81 lower ends, the pivot shaft 86 of trammel beam 81 is located at the left side of trammel beam 81 lower ends, and balance wheel 82 is positioned at the place ahead of wheel and ground contact point S, pivot shaft 86 is positioned at the rear of wheel and ground contact point S, trammel beam 81 tops are provided with a draw-in groove 85 that is used for fixing spring assembly 83, by this spring assembly 83 respectively with second pulley 52, the axle close-fitting of the 3rd pulley 53, its effect is upwards swing of reset assembly 60 when centrifugal wheel 5 rolls forward, the axle that drives the 3rd pulley 53 is upwards swing and apply application force by 83 pairs of trammel beams 81 of spring assembly simultaneously, simultaneously because the pivot shaft 86 of balanced component 80 is motionless with balance wheel 82 relative ground, make that the axle of 81 pairs the 3rd pulleys of trammel beam also is the original position of location restore that 60 1 antagonistic forces of reset assembly are kept reset assembly 60 simultaneously, in the present embodiment, trammel beam 81 is positioned at midway location, promptly between the 3rd pulley 53 and the 4th pulley 54, the position of trammel beam 81 is not unique in fact, size according to wheel can also be done different adjustment, must be but balance wheel 82 acts on the acting point of slip drum 10 on the right side of wheel acting point, i.e. the wheel direction of advancing; Spring assembly 83 is relativity attaching partss in balanced component 80 and reset assembly 60, purpose is to make the pulley assembly 50 with reset assembly 60 close-fittings recover original position, in the present embodiment, spring assembly 83 is bonding jumpers of a bending, one end 831 is around on the axle of the 3rd pulley 53, and 832 ones of the other ends are turned up and injected in the draw-in groove 85 of trammel beam 81; Certainly, spring assembly 83 also can be the spring of other type, such as the retractility spring.

Join or close-fitting with other assembly is moving for pulley assembly 50, balanced component 80 relatively stablely, set gradually reset assembly 60 and positioning component 70 respectively in the both sides of said modules, as shown in Figure 3.

Analyze from terms of mechanics, the centrifugal wheel of the utility model comprises balancing device and synchronous driver two large divisions, balancing device designs according to lever principle and condition, and as shown in Figure 8, first pulley 51 is A with the contact of slip drum 10, second pulley 52 is B with the contact of slip drum 10, trammel beam 81 power arm points are D, and trammel beam 81 resistance points are E, and trammel beam 81 fulcrums are N, slip drum 10 is S with the ground contact point, and balance wheel 82 is C with the contact of slip drum 10.Slip drum 10 is not remained static as the time spent by external force on level ground.When the gravity of vehicle body by positioning component 70 and when affacting first pulley 51, slip drum 10 is subjected to force unbalance, the A point is downward, make by the S point and a little upwards to affact the B point, pendulum reset assembly 60 is stressed on the stressed promotion reset assembly 60 of B point, by reset assembly 60 power is passed to spring assembly 83, promote trammel beam 81 by spring at power arm point D, and power is delivered on the C point, according to lever equilibrium condition, DE=EN, CS=SB, as can be seen from the figure, can only make and to descend and can not make the rising of B point, i.e. DE=EN, and CS ≠ SB, CS/SB=0.3 in the present embodiment; Synchronous driver is according to lever, equivalence, the centre-of-gravity principle design-calculated, mainly with eccentric drive assembly 40, power wheel 20, center transmission gear 21, slip drum 10 is formed, force analysis as shown in Figure 9, eccentric drive assembly 40 is subjected to the transmission of car semiaxis and rotates, power is passed to center transmission gear 21, center transmission gear 21 passes to slip drum 10 to power by power wheel 20, drive wheel by slip drum 10 and produce friction thrust forward on ground, because balancing device makes the C point of slip drum 10 be subjected to a downward power, contact point S has a power control slip drum 10 that makes progress to descend, the drum 10 that slides this moment is that rotate in the axle center with the C point, the C point just can descend, the B point will rise simultaneously, because the gravity of balancing device only can make the C point descend, rise and can not control the B point, be that axle center and central synchronous transmission gear point of engagement F form radius this moment with C, radius like center transmission gear 21 prolongs, but fall in the C point under between the sideline that the sagging center of gravity of balancing device this moment is ordered by center transmission gear 21 and C and make radius formation leverage, at this moment S point power is upwards had an effect, and center transmission gear 21 and eccentric drive gear 42 engagement point of contacts are made progress.

Use wheel of the present utility model when installing and using, sheave shaft 511 with bonded assembly first pulley 51 on the positioning component 70, sheave shaft 541 on the 4th pulley 54 and pivot shaft of the trammel beam 81 in the balanced component 80 86 and car chassis crossbeam, the axostylus axostyle 41 of eccentric drive assembly 40 is captiveed joint with the car semiaxis, different with the semiaxis of existing vehicle, the rotation direction of eccentric drive assembly 40 is anticlockwise directions, driving power wheel 20 clockwise directions rotates, simultaneously, the slip drum 10 affixed with power wheel 20 also rolls before the clockwise direction, with four pulleys in the pulley assembly 50 that guide rail 13 in the slip drum 10 matches and the balance wheel 82 on the balanced component 80 relative rolling takes place also, vehicle moves ahead.Like this, the weight of vehicle is born first pulley 51, the 4th pulley 54 and trammel beam 81, can alleviate the burden of the load-bearing of semiaxis, and vehicle weight acts on the C point by first pulley 51, this stress point C is in the front upper place of wheel and ground contact point S, and the result is that automobile is more more laborsaving than existing to overtake the time.

It can also be seen that the labor-saving effect of the centrifugal wheel of the utility model by following test result:

Detect through driving process, obtain following data (it is identical to be full of electric weight) before and after the repacking of same Segway Human Transporter:

Former wheel-mounted remoulded car wheel

Trigger voltage 26.58V 26.5V
