Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described further:
Fig. 1 to Fig. 4 shows a kind of four-wheel pivot stud mechanism, including 1, four wheels 8 of track plates and steering link machine
Structure.Four wheels 8 are rigidly connected with corresponding vertical rotation axis 6 respectively and pass through vertical rotation axis 6 and are arranged on track plates 1 lower surface
On, steering linkage is arranged on track plates 1 upper surface.It is a round circular orbit in the middle of track plates 1, in the present embodiment,
Round circular orbit is an annular groove 12;Track plates 1 four jiaos is respectively arranged with 1/4 circular groove 13, and track plates about 1 two ends are respectively arranged with always
Groove 11.Steering linkage includes steering crank 2, connecting rod 3, center crank 4, drive shaft 5 and turning-bar 7.Drive shaft 5 is arranged on
In annular groove 12, drive shaft 5 lower end is through track plates 1 center and passes through shaft coupling and is connected with motor 10, drive shaft 5 upper
End is connected with center crank 4 central rigid to drive center crank 4 to rotate.The two ends of center crank 4 are respectively articulated with a connecting rod 3,
The connecting pin of center crank 4 two ends and connecting rod 3 moves along annular groove 12.The other end of connecting rod 3 and two symmetrically arranged turn to
Crank 2 is hinged, and the swivel pin of this end of connecting rod 3 moves along straight trough 11.The other end of steering crank 2 cuts with scissors with corresponding turning-bar 7
Connecing, the swivel pin of this end moves along 1/4 corresponding circular groove 13.The other end of turning-bar 7 and corresponding vertical rotation axis 6 upper end
It is rigidly connected.The lower end of vertical rotation axis 6 is connected with wheel 8, as shown in Figure 3 and Figure 4 through track plates 1 and by wheel carrier 9.
During work, as it is shown in figure 1, this state 1 time, chassis can be moved along X-direction；When needing to turn, motor 10
Driving drive shaft 5 to rotate counterclockwise by shaft coupling, drive shaft 5 drives center crank 4 to rotate counterclockwise, the two of center crank 4
End connecting pin is along annular groove 12 counterclockwise movement, thus drivening rod 3 moves, and the other end of connecting rod 3 is X-axis side along track plates 1
To straight trough 11 slide；Connecting rod 3 drives four steering cranks 2 to move, and steering crank 2 drives the freedom of corresponding turning-bar 7
End slides in 1/4 circular groove 13 on track plates 1, thus drives vertical rotation axis 6 rigidly connected with turning-bar 7 to rotate, vertically
Rotating shaft 6 is rotated by wheel carrier 9 band motor car wheel 8 rigidly connected with it；Turning-bar 7 drives vertical rotation axis 6 to turn over 90 degree and arrives pole
Limit is put, and motor 10 quits work, and completes pivot stud, reaches state 2, as in figure 2 it is shown, chassis can be moved along Y direction
。
In like manner, when needing to be redirect to state 1 by state 2, the direction of rotation of motor 10 need to only be changed.
Above in conjunction with accompanying drawing, this utility model is carried out exemplary description, it is clear that realization of the present utility model is not subject to
