Drive-connecting shaft be respectively arranged between the upper and lower both sides of first right connecting rod 4 and second right connecting rod 5.The connection is set
Block 11 can make the connecting rod keeping parallelism at its both ends, so that steering mechanism 100 is more stable, control is more accurate.
Again as shown in Figures 3 and 4, the mounting seat 7 of the first mounting seat 6 and second is pivot joint block, the pivot joint block
Both ends are outward-dipping with respect to the length direction of itself to extend articulated section 100a, the articulated section 100a and corresponding connecting rod
Pivot joint, specifically, one end of the left connecting rod 3 of the first left connecting rod 2 and second is articulated in the two of wherein one pivot joint block respectively
On the 100a of articulated section, pivot joint central shaft is in vertical；One end of the right connecting rod 5 of first right connecting rod 4 and second is articulated in separately respectively
On two articulated section 100a of one pivot joint block, pivot joint central shaft is in vertical.By the both ends of the pivot joint block set two to
The articulated section 100a of outer extension, therefore, when two connecting rods are articulated in the two articulated section 100a respectively and drive the pivot joint block
During swing, the center of rotation 100b of the pivot joint block can be made to offset laterally, so that center of rotation 100b can be more
The geometric center of wheel on the outside of it, and then the purpose of radius of turn is reduced, it is simple in construction, be advantageous to turning machine
Structure and the body structure on wheel periphery carry out more reasonably design arrangement.
With reference to Fig. 5, during steering, the steering spindle 200 is rotated, rotates counterclockwise the steering spindle 200, the steering spindle
200 drive the counter-clockwise swing of swing rod 9, and the other end of the swing rod 9 promotes second right connecting rod 5 to move right, described
Second right connecting rod 5 drives the quadrilateral area where it so that second mounting seat 7 is swung, and at this moment the right wheel 400 is to the left
Swing；At the same time, first right connecting rod 4 is moved to the left, and first left connecting rod 2 is promoted by the gangbar 8, described
First left connecting rod 2 is moved to the left and drives the quadrilateral area where it so that first mounting seat 6 is swung, at this moment described
Revolver 300 is swung to the left simultaneously；Therefore, steering mechanism 100 drives revolver 300 and right wheel 400 to turn to the left side.Similarly, can drive
Move the revolver 300 and right wheel 400 turns to the right.
Compared with prior art, by the utility model is by using the left connecting rod 3 of the first left connecting rod 2 and second and institute
State the pivot joint of the first mounting seat 6 and form a parallelogram, utilize the right connecting rod 5 of first right connecting rod 4 and second and described the
The pivot joint of two mounting seats 7 forms another parallelogram, then by a gangbar 8, makes the gangbar 8 respectively with described first
The right connecting rod 4 of left connecting rod 2 and first is pivotally connected, so that two parallelogram realize linkage, therefore, passes through a drive rod 1 and institute
Two parallelogramming deflections can be driven simultaneously by stating any one connection of the second left connecting rod 3 and the second right connecting rod 5, and then make institute
State the first mounting seat 6 and the second mounting seat 7 is swung, realize the car to being installed in the mounting seat 7 of the first mounting seat 6 and second
Wheel is driven the purpose of steering, and its is simple in construction, and only needs to use a drive rod 1 to be connected with a wherein connecting rod
The steering of two wheels is controlled, it is easy to control.Further, since the gangbar 8 be articulated in respectively with first left connecting rod 2 and
First right connecting rod 4, therefore the one of which of two parallelogram is smaller on another one influence in vibrations, therefore be advantageous to improve
Stationarity when vehicle travels, makes driving more comfortable
