With reference to the accompanying drawings illustrative embodiments of the present invention is described in more details.In figure, identical reference character is for indicating identical parts, and should understand, all vibrational power flow shown in the drawings are schematically, it is not the concrete relative position for limiting the device shown in it, element, mechanism, unless be consistent with the clear and definite explanation drawn in conjunction with following detailed description.
Fig. 1 schematically illustrates the speed change gear of a mode of execution according to a first aspect of the present invention.As can be seen from the figure, this speed change gear 1 has the first axle 2, first clutch 3, second clutch 4, planetary gears 5, second axle 6, planetary gears 5 comprises sun gear 7, gear ring 8, planet wheel 9, planet carrier 10, planet wheel can on described planet carrier rotation and around described sun gear and described gear ring revolution, wherein, driving disc and the first axle 2, the gear ring 8 of first clutch 3 are arranged integratedly, sun gear 7 is arranged integratedly with the driven disc of second clutch 4, and driven disc, second axle 6 of planet carrier 10 and first clutch 3 are arranged integratedly.And can find out, the first axle 2, first clutch 3, second clutch 4, planetary gears 5 and the second axle 6 are coaxial, and namely their center is all on same straight line.
Utilize this speed change gear, when first clutch 3 is closed, second clutch 4 is opened, and when first clutch 3 open, second clutch 4 close time, the transmission of different drive ratios can be realized respectively.Be below illustrating of two kinds of drive states.
When first clutch 3 is closed, second clutch 4 is opened, achieve the first drive state: power inputs from the first axle 2, cause the rotation of the first axle 2, and then, because the driving disc of the first axle 2 and first clutch 3, gear ring 8 are arranged, integratedly so the driving disc of first clutch 3, gear ring 8 also rotate integratedly.Because first clutch 3 closes, so its driven disc also rotates together, drive the second axle 6 to rotate, realize Power output.Meanwhile, because planet carrier 10 and the second axle 6 are wholely set, so planet carrier 10 also rotates together, planet wheel is driven to rotate together.Visible, now the first axle 2, first clutch 3, planetary gears 5, second axle 6 rotate simultaneously, achieve the power transmission that gear ratio is 1.In this transmission process, if second clutch 4 closes suddenly, then can realize the brake operating of transmission system.Such as, so second clutch 4 also can substitute with common braking device, strap braking device.
When first clutch 3 open, second clutch 4 close time, achieve the second drive state: power inputs from the first axle 2, cause the rotation of the first axle 2, now, because first clutch 3 is opened, so power is no longer passed to its driven disc from the driving disc of first clutch 3, and be through the rotation that the first axle 2 drives gear ring 8, revolve round the sun around sun gear 7 while making planet wheel 9 produce rotation on planet carrier 10; Meanwhile, planet wheel 9 drives planet carrier 10 to rotate.And then the rotation of planet carrier 10 makes the second axle 6 rotate, and achieves another gear ratio determined by the characteristic of the sun gear 7 of planetary gears 5, gear ring 8, planet wheel 9.Visible, now first clutch 3 not transferring power.
