Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The selection mechanism of connecting rod push-and-pull commutation of the present invention, comprise driving lever 2, first connecting rod 4, second connecting rod 6, third connecting rod 7, by lever 10 and steering equipment 9, one termination power source or drive unit of driving lever 2, the other end by the first fraising 3 simultaneously with first connecting rod 4 and second connecting rod 6 hinged, the middle part of first connecting rod 4 is hinged with fixed support 1 by the second fraising 5, the other end of first connecting rod 4 is hinged with third connecting rod 7 by the 4th fraising 22, and third connecting rod 7 the other end is cross-shaped with second connecting rod 6 the other end and be connected steering equipment 9 simultaneously, steering equipment 9 comprises host node 16, host node 16 reams 8 with hinged by lever 10 (namely needing the device commutated) by the 3rd, the bilateral symmetry of host node 16 is welded with the first welding body 15 and the second welding body 21, first clutch rolling disc 11 is arranged on the first welding body 15 by clutch shaft bearing 14, make it can rotate around the first welding body 15, second clutch rolling disc 18 is arranged on the second welding body 21 by the second bearing 20, make it can rotate around the second welding body 21, first clutch rolling disc 11 and the second clutch rolling disc 18 are symmetrical set, first clutch rolling disc 11 is provided with the first through hole 13 passed for third connecting rod 7, first axle jack 12 that can pin third connecting rod 7 is provided with in first through hole 13, second clutch rolling disc 18 is provided with the second through hole 17 passed for second connecting rod 6, second axle jack 19 that can pin second connecting rod 6 is provided with in second through hole 17.
The axle jack that the present invention adopts can be various forms of clutch, its major function makes axle and axle jack be in separated state, namely axle can slide in the through hole on clutch rotating disk, and axle also can be made to lock with axle jack and be connected, namely axle and clutch rolling disc form a fixed connection.
The working principle of mechanism of the present invention is as follows:
1, driving lever 2 will move through the first fraising 3 and pass to first connecting rod 4 and second connecting rod 6, scissors mechanism is constituted because the intermediate portion of first connecting rod 4 and fixed support 1 are linked together by the second fraising 5, therefore the first fraising 3 on first connecting rod 4 does and driving lever 2 motion in the same way, and the 4th fraising 22 does the motion reverse with driving lever 2, thus make the direction of action of second connecting rod 6 contrary with the moving direction of third connecting rod 7;
2, the first clutch rolling disc 11 welds body 15 by clutch shaft bearing 14 and first and is connected, and it can rotate around the first welding body 15, but can not depart from the first welding body 15; Second clutch rolling disc 18 welds body 21 by the second bearing 20 and second and is connected, and the second clutch rolling disc 18 can rotate around the second welding body 21, but can not depart from the second welding body 21;
3, when being moved in the same way with driving lever 2 by lever 10, lock second connecting rod 6 by the second axle jack 19, then second connecting rod 6 drives host node 16 to make positive movement, and host node 16 drives Passive part 10 to move in the same way by the 3rd fraising 8;
When reversing motion need be done with driving lever 2 by lever 10, third connecting rod 7 is locked by the first axle jack 12, and the second axle jack 19 is separated with second connecting rod 6, then third connecting rod 7 drives host node 16 reversing motion, and host node 16 drives Passive part 10 to do reversing motion by the 3rd fraising 8.
First axle jack 12 of the present invention and the second axle jack 19 can not be locked simultaneously, not so steering equipment 9 cannot move, the length of second connecting rod 6 and third connecting rod 7 makes it can not disconnecting clutch by calculating, and second connecting rod 6 and third connecting rod 7 are in different planes, and does not have intersection point.
