Support 7 is fixed on carrier frame 1, and motor 9 is rotated after being powered, by a series of connectors, so as to drive omni-directional wheel 5 to rotate.
As shown in Figure 4 and Figure 5, in the feasible embodiment of the present invention, two adjacent omni-directional wheel drivetrains 2 are also set
The resilient suspension system 3 for making all omni-directional wheel drivetrains 2 to land is equipped with, so as to form omni-directional wheel suspension system, makes two entirely
It can somewhat float, it is ensured that four omni-directional wheels 5 of whole carrier frame 1 can land, prevented at uneven ground to wheel 5
There is the problem of part omni-directional wheel 5 is hanging, so that whole chassis can also keep enough stability in broken terrain,
Improve the applicability on omni-directional wheel chassis.
Specifically, described resilient suspension system 3 include be set in parallel in the both sides of omni-directional wheel 5 and respectively with wheel shaft
The omni-directional wheel suspension plate 13 that two ends are rotatably assorted, one end of two omni-directional wheel suspension plates 13 is fixed on chassis by hinge 12 respectively
On framework 1, the other end is connected on the elastic buffer frame being fixed on carrier frame 1 with fluctuating, the fixed motor cabinet 7
It is connected by omni-directional wheel suspension plate 13 with carrier frame 1, now, because fixed motor cabinet 7 is integrally fixed at omni-directional wheel suspension plate
On 13, in order to ensure its intensity needs, square groove shape fixes motor cabinet 7 and replaces with square-tube-shaped motor fixation aluminum pipe 10.
Specifically, described elastic buffer frame includes being welded on door shape fixed mount on the carrier frame, vertically
Through the guiding optical axis 11 being arranged on the door shape fixed mount, described one end of omni-directional wheel suspension plate 13 is provided with along described and is oriented to

The outer ring of bearing is fixed on the bottom of carrier frame 1, and the inner ring of the dining table bearing is secondary by some equally distributed rectilinear movements
Connection transmitting fixed block.
Specifically, the secondary inner ring for including optical axis 19, being fixed by screws in the dining table bearing of described rectilinear movement
On clamped-in style shaft stool 20, correspondingly be fixed on transmitting fixed block 17 on linear bearing 18, one end of the optical axis is fixed on
On clamped-in style shaft stool 20, the other end is slidably matched with linear bearing 18.When the piston rod of cylinder 15 promotes transmitting fixed block 17
When moving down, the linear bearing 18 being fixed on transmitting fixed block 17 is driven to be moved down along optical axis 19 is synchronous, until transmitting fixed block
17 are displaced downwardly to and are fully contacted with ground, after the contact ground of fixed block 17 is launched, pass through omni-directional wheel drivetrain 2 and drive carrier frame
1, which rotates to an angle, realizes the position adjustment to transmitting retention mechanism 4.When carrier frame 1 rotates, the outer ring of the dining table bearing
Synchronize rotation, and the inner ring of dining table bearing because by move linearly it is secondary be connected with launching fixed block 17, therefore, dining table
The inner ring of bearing keeps the state of geo-stationary with transmitting fixed block 17, namely during the rotation of carrier frame 1, can drive the dining table
The outer ring of bearing rotates around the inner ring of static dining table bearing.
In the feasible embodiment of the present invention, the bottom of described transmitting fixed block 17 is provided with for increasing adhesive force
Rubber or sucker, during according to rubber, then select the larger rubber of frictional force, are connect so as to improve transmitting fixed block 17 with ground
Adhesive force when touching, it is ensured that transmitting fixed block 17 can remain transfixion when carrier frame 1 rotates, prevents fixed point hair
The problem of sidesway is easily produced due to the recoil of transmitting when penetrating.
The operation principle and process of the present invention is further illustrated below by application method：
When needing to compare accurately continuous fixed point transmitting, when chassis is moved to specified location and starts fixed point transmitting, the cylinder
15 are moved downward, and transmitting fixed block 17 is contacted with ground, and by the frictional force of rubber（Or the suction of sucker）It is fixed on ground
On, now whole chassis can surround center rotating by the driving of dining table bearing and four omni-directional wheels 5, realize trigger mechanism
The function of Plane Rotation is there is provided the effect of a head, simultaneously as transmitting fixed block 17 has necessarily when being contacted with ground
Adhesive force, the influence that brings of transmitting recoil can be eliminated again, prevents that the recoil due to transmitting from producing sidesway, causes again
The problem of transmitting needs adjustment position.
