Mark in above-mentioned figure is: 1, driving gear, 11, input shaft, 2, driven gear, 21, output shaft, 3, connecting rod, 4, limiting stopper, 41, guide groove, 5, adapter shaft.
The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment mono-
Referring to Fig. 1, 2, 3, a kind of transmission device of vehicle variable ratio steering, comprise the driving gear 1 and the driven gear 2 that are meshed, the eccentric gear that described driving gear 1 and driven gear 2 are circle, the size of driving gear 1 and driven gear 2, the number of teeth, eccentric throw equates, initial loading timing, the maximum radius place of driven gear 2 is aimed at the minimum radius place of driving gear 1, when bearing circle is offset to both sides from initial middle part state, transmitting ratio reduces gradually, described driving gear 1 and driven gear 2 have two groups, two driving gears 1 connect gear center by an adapter shaft 5, two driven gears 2 connect gear center by another root adapter shaft 5, driving gear 1 and driven gear 2 adopt two groups, transmission is more reliable, stable, connecting rod 3 two ends hinged two adapter shafts 5 respectively, because driving gear 1 and driven gear 2 are Knucle-gears that size is identical, gear center is apart from remaining constant, driving gear 1 and driven gear 2 remain engagement because of the effect of connecting rod 3.In the engagement process of driving gear 1 and driven gear 2, because input shaft 11 and output shaft 21 is eccentric with driving gear 1 and driven gear 2, in rotation process, the wheelbase of input shaft 11 and output shaft 21 can change, but variable quantity is little, therefore input shaft 11 ends or output shaft 21 end one end are set to mobilizablely, meet the demand that width between centers in transmission process changes.
Limiting stopper 4 is arranged on input shaft 11 ends or output shaft 21 ends, and limiting stopper 4 is provided with the guide groove 41 that can slide for axle.Provide activity space by guide groove 41 to axle.
Input shaft 11 ends or output shaft 21 end one end also can adopt other movable mounting meanss, as being arranged in frame by a rocking bar, other fixed mechanisms also can be set on car body.
Movable end axle connects other mechanism driving by versatile spindle.
Embodiment bis-
As shown in Figure 4, a kind of vehicle variable ratio steering system, comprise the driving gear 1 and the driven gear 2 that are meshed, also comprise the contiguous block 3 that connects driving gear 1 and driven gear 2 core wheels, contiguous block 3 is sleeved on rotationally driving gear 1 and driven gear 2 is taken turns in the heart;
Also comprise input shaft 11 and output shaft 21, input shaft 11 is arranged on driving gear 1 and departs from center, and output shaft 21 is arranged on driven gear 2 and departs from center; The bearing circle being connected with input shaft 11 is in the time of initial medium position, and input shaft 11 point of connection are positioned at the side near point of mesh on driving gear 1, and output shaft 21 point of connection are positioned at the side away from point of mesh on driven gear 2;
Input shaft 11 ends are arranged on car body by limiting stopper 4, and limiting stopper 4 is provided with the guide groove 41 that can slide for input shaft 11.Activity space is provided to input shaft 11 by guide groove 41, input shaft 11 ends are by universal coupling closure dish.
Adopt after above-mentioned structure, at bearing circle during in initial middle part state, the transmitting ratio maximum of transmission device, the Vehicular turn angle amount forming when steering wheel rotation is minimum, in the time that straight line is run at high speed, even when chaufeur is controlled bearing circle by mistake, larger owing to rotating at vehicle, the corner amount of vehicle is also very little, can not cause danger.In the time that needs turn to, along with the increase of steering wheel angle, transmitting ratio reduces gradually, increases steering sensitivity, and the entirety that improves vehicle is handling.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
