2constantly reduce.In said process, due to R
1and R
2be all continually varying, so both ratio also increases continuously, velocity ratio also reduces continuously, thereby realizes the object of the electrodeless speed ratio that diminishes.After above reduction speed ratio completes, the structure of stepless speed variator as shown in Figure 4 and Figure 5.
In the time of need to slowing down, the hydraulic oil of opening in reflux valve 208, the first oil hydraulic cylinders 205 is constantly back in the second oil hydraulic cylinder 212, and now the first conically shaped 203 and the second conically shaped 210 all occur and motion contrary in above-mentioned accelerating process, make R
1constantly reduce R
2constantly increase, velocity ratio increases thereupon continuously, thereby realizes the object of electrodeless increase speed ratio.After above speed increasing ratio completes, the structure of stepless speed variator as shown in Figures 2 and 3.
From above-mentioned working principle, the stepless speed variator of above-described embodiment is also applicable to the drive speed transmission of pneumatic-typed, only oil hydraulic pump 207, the first oil hydraulic cylinder 205, the second oil hydraulic cylinder 212 all need be changed into air pressure.In addition, can adjust the tapering of the first conically shaped 203 and the second conically shaped 210 and the running parameter that length is adjusted stepless speed variator, to meet different demands.
In addition, for the stepless speed variator of above-described embodiment, driving shaft 202 and driven shaft 209 can be arranged on homonymy (as shown in Figure 6), also can be arranged on opposition side (as shown in Figure 2 and Figure 4).When being arranged on homonymy, as shown in Figure 6, the setting party of the first conically shaped 203 and the second conically shaped 210 is to also identical; When being arranged on opposition side, as shown in Figure 2 and Figure 4, the setting party of the first conically shaped 203 and the second conically shaped 210 is to also contrary.
The structure of above-mentioned stepless speed variator can also further be improved, to reach more technique effect, and as shown in Fig. 2-7, literary composition specific as follows.
For example, can increase shell 204, the first conically shaped 203 and the second conically shaped 210 are arranged to the inside of shell 204.So both can protect the first conically shaped 203 and the second conically shaped 210 not by F. O. D; can play position-limiting action to the first conically shaped 203 and the second conically shaped 210 again; avoid the first conically shaped 203 and the second conically shaped 210 that other axially outer displacement occurs, affect the normal work of stepless speed variator.Certainly, also can as required driving belt 215 other parts such as grade be arranged on to the inside of shell 204.
In addition, for structure space design is rationalized more, can also make driving shaft 202 and driven shaft 209 be rotatably connected on shell 204.
After having had above-mentioned shell 204, can also on shell 204, establish again a touch switch 213, this touch switch 213 for: when the first conically shaped 203 touches touch switch 213, touch switch 213 is controlled oil hydraulic pumps 207 and is closed.As can be seen here, this touch switch 213 can limit the displacement distance of the first conically shaped 203, to avoid the first conically shaped 203 to move the situation separated with first round piece 201 behind position, and can obtain reasonably or the velocity ratio of adaline motor-car by changing the position of touch switch 213.
When driving belt 215 is arranged on the inside of shell 204, can also on shell 204, by spring 214, connect a pulley, the groove of pulley compresses driving belt 215, with moment tensioning driving belt 215, makes its more effectively transferring power.In addition, for abnormal deformations (such as bending etc.) occur for restraining spring 214, a hollow cylindrical stent can also be first set on shell 204, spring 214 be placed in to the inside of cylindrical stent, now cylindrical stent can be to 214 position-limiting actions of spring.
For first round piece 201, be connected with the rolling of the first conically shaped 203, can adopt following structure to realize:
As shown in Figure 7, first round piece 201 is inlaid with the universal pearl 217 of the first universal pearl 217, the first near the one end in the axle center of driving wheel and rolls and contact with the first conically shaped 203.
Certainly, second takes turns piece 211 is connected also and can adopts as above structure with the rolling of the second conically shaped 210, second takes turns piece 211 and is inlaid with the second universal pearl near the one end in the axle center of follower, and the second universal pearl rolls and contacts with the second conically shaped 210.
Universal pearl mentioned above can adopt various structures with inlaying of piece of wheel, the first universal pearl 217 of take is example, a lock pin 216 is set in the termination of first round piece 201, lock pin 216 passes the center hole of the first universal pearl 217 movably, and the length direction of lock pin 216 is axial vertical with the first conically shaped 203, so both can guarantee that the first universal pearl 217 was fixedly embedded on first round piece 201, can guarantee again that universal pearl 217 was in the male cone (strobilus masculinus) rotation of the first conically shaped 203.
For the configuration design of the first conically shaped 203, can preferably adopt conical hollow cylinder, to alleviate the weight of whole device, thereby alleviate energy consumption.In like manner, the second conically shaped 210 also can adopt conical hollow cylinder.
In addition, echo mutually with the profile of the first conically shaped 203, the second conically shaped 210, the cavity of driving shaft 202 and driven shaft 209 also can be arranged to taper, so that spacing better to the first conically shaped 203, the second conically shaped 210.
Embodiment two
A Motor Vehicle, it can adopt the stepless speed variator of above-described embodiment one.
Certainly, the stepless speed variator in this Motor Vehicle also can do to optimize as above.
In addition, for the ease of controlling, the accelerating unit arranging in Motor Vehicle can be connected with oil hydraulic pump 207, is convenient to the electrodeless speed ratio that reduces; And braking device can be connected with reflux valve 208, be convenient to electrodeless increase speed ratio.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
