The specific embodiment:

Referring to accompanying drawing, spherical wheel (1) is made up of the uniform hollow ball shell of wall thickness, the two ends of wheel shaft (4) connect firmly on spherical wheel (1), the centre of sphere of the axis of wheel shaft (4) by spherical wheel (1) and parallel with horizontal road (15), [annotate: wheel shaft (4) all adopts simplified painting in Fig. 2 and Fig. 4] wheel axle gear (3) connects firmly on wheel shaft (4), drive axle (2) is enclosed within on the wheel shaft (4), and can rotate around the axis of wheel shaft (4), connect firmly swinging axle (6) on the drive axle (2), the axis normal of its axis and wheel shaft (4), and be parallel to horizontal road (15), vehicle frame (11) then is suspended on the swinging axle (6), vehicle frame (11) can swing around the axis of swinging axle (6), and (seeing shown in Fig. 2 double dot dash line), an end of swinging axle (6) connects firmly wobble gear (7).Driving control device (14) constitutes (not drawing in detail among the figure) by wireless remote controlled receiver, battery pack, motor, decelerator, this device connects firmly on vehicle frame (11), power is by reducer output shaft → universal joint → power transmission shaft (16) → universal joint → driving shaft (17) → driven wheel (5), driven wheel (5) (see figure 1) that is meshed with wheel axle gear (3).When power transmission shaft (16) when rotating forward or backwards, drive axle (2) and car body [that is: the summation of various parts that go up to install of vehicle frame (11) and vehicle frame (11), hereinafter to be referred as car body] will be together rotate (seeing Fig. 1, Fig. 3) forward or backward around the axis of wheel shaft (4).Power transmission shaft (16) is by two sections concentric circumferentially fixing, and axially movable axle forms by spline or the connection of slip flat key, and the length of power transmission shaft (16) is scalable, the transmission of power when turning with assurance.Steering control device (12) is made of motor and decelerator, also connect firmly on vehicle frame (11), power supply is from battery pack, control command is also from receiver of remote-control sytem, its power is by reducer output shaft → shaft coupling → turning-bar (10) → shaft coupling → steering spindle (the 9) → tooth sector (8) of steering control device (12), and tooth sector (8) is meshed with wobble gear (7).The output shaft of this steering power can rotate forward or backwards by the angle of telecommand appointment, thereby make the car body that is suspended on the swinging axle (6) rotate corresponding angle (angle is usually between 0 °-90 °) to the left or to the right, referring to Fig. 2 double dot dash line part and Fig. 4 around the axis of swinging axle (6).

In the inactive state of the car of this spherical structure before straight-line travelling, the focus point of its car body (13) is positioned on the vertical join line of contact point of the centre of sphere of spherical wheel (1) and wheel and level ground (15) (hereinafter to be referred as vertical line), the quality of car body normally the quality of running gear 5-20 doubly, the position of focus point (13) is lower than the position of the centre of sphere of spherical wheel.At this moment whole vehicle is similar to the tumbler of a poised state.When power transmission shaft (16) forward rotation (seeing shown in Fig. 1 arrow) thus driving drive axle (2) and car body turns an angle (between 0 °-90 °) forward during to position shown in Figure 3 around the axis of wheel shaft (4), equilibrium of forces during inactive state is destroyed, the gravity of the focus point of car body (13) becomes an active force that spherical wheel (1) is rotated round about, and increase along with rotational angle (between 0 °-90 °), its active force is also big more, when resistance that the effect of this power is rolled forward greater than spherical wheel (1), spherical wheel (1) just begins to roll forward, like this, power transmission shaft (16) rotates continuously, spherical wheel (1) also just constantly rolls forward, thereby finishes advancing of car load.When the power output of design driven control device (14), under the fixed condition of spherical wheel (1), when the output peak torque, the maximum angle that this moment of torsion makes car body can rotate relative to vertical line should be less than 90 °, to guarantee that car body can be around the continuous 360 ° of rotations of wheel shaft (4) when car is started to walk, thereby cause spherical wheel (1) only in the original place swing, can not normally start to walk, travel.Otherwise the principle the when car of spherical structure retreats (reversing) is also like this.

As a same reason, when turning-bar (10) reverse rotation (seeing shown in Fig. 1 arrow) certain angle, then can make car body around swinging axle (6) certain angle (usually between 0 °-90 °) that turns right, during to position shown in Fig. 2 double dot dash line, spherical wheel (1) also deflection to the right when rolling forward, reach the state shown in figure (4), at this moment the axis of wheel shaft (4) just and the angle of horizontal road (15) between forming one 0 °-90 °, the constant (see figure 4) of angle that keeps the relative swinging axle (6) of body gravity point (13) to turn over, the speed of advancing is identical, at this moment the route that spherical wheel rolls forward just forms a circle that right-handed radius is identical, the principle that the car of Here it is spherical structure is turned right.The sample car experimental result shows, is lower than in the turning speed per hour under 5 kilometers/hour the situation, and the min. turning radius of the car of spherical structure is less than the diameter of spherical wheel, and it is very flexible to turn.Equally, the principle during left-hand bend is also like this.
