Embodiment
As shown in Figure 1, this automobile speed changer comprises casing, is arranged on 2,3,4, three output shafts 5,6,7 of three input shafts on the casing.Be provided with in the casing and three three input engaging and disengaging gear 8,9,10 that input shaft is corresponding, with three three output engaging and disengaging gear 11,12,13 that output shaft is corresponding.
Shown in Fig. 2,3, the input engaging and disengaging gear comprises housing 14 and is positioned at the gear shape commentaries on classics core 15 of housing, commentaries on classics core 15 is coaxial installation with housing 14 and is provided with middle gear ring 16 between the two that middle gear ring 16 is eccentric installation with housing 14 and is Spielpassung between the two.Change and be provided with oil sucting cavity 17, crowded oil pocket 18 between core 15 and the middle gear ring 16.The end cap 19 that is fixed on the housing 14 fits tightly with the end face that changes core 15 end faces, middle gear ring 16.End cap 19 is provided with the oil inlet hole 20 that is communicated with oil sucting cavity.Change radially be provided with oil sucting cavity 17 on the core 15, squeeze that oil pocket 18 communicates unload oilhole 21, unload oilhole 21 the other ends and communicate with the axis hole of commentaries on classics core 15.Change the interior controlling rod 22 of planting of axis hole of core, be provided with blind hole 23 in the controlling rod 22 vertically, blind pore wall is provided with through hole 24.
Input shaft 2,3,4 fixes as one with the commentaries on classics core of importing engaging and disengaging gear 8,9,10 respectively, and input shaft is nested with on the controlling rod 22 of input engaging and disengaging gear.Input shaft 2,3,4 be provided with each controlling rod on the through hole 24 corresponding oilholes 25 that unload greatly.
The working principle of this engaging and disengaging gear is as follows: when the needs engaging and disengaging gear " closed ", controlling rod 22 is inserted into to be changeed in the core 15 and guarantees that the oilhole 21 that unloads that controlling rod 22 will change on the core blocks.Power drives commentaries on classics core 15 by input shaft and rotates together.In the rotation process, thereby the oil sucting cavity 17 that changes between core 15 and the middle gear ring 16 becomes big certain attraction force that forms gradually, by oil inlet hole 20 oil in the mission case 1 is sucked.Change core 15 and be rotated further, when oil sucting cavity 17 beginnings that oil is housed diminished gradually, oil wherein was squeezed, and oil sucting cavity 17 has promptly become crowded oil pocket 18.Be rotated further when changeing core 15, the oil pressure that squeezes in the oil pocket 18 is elevated to maximum value, and gear ring 16 rotated together in the middle of commentaries on classics core 15 can drive.Install because middle gear ring 16 is that out-of-alignment is eccentric with housing 14, rotate together so commentaries on classics core 15 drives housing 14 by middle gear ring 16; Realized housing and the end cap output thereof of power by clutch.
When the needs engaging and disengaging gear " from " time, by operation controlling rod 22 is extracted out from change core 15 gradually, unload oilhole 21 and be opened gradually.Change core 15 in rotating process, oil sucting cavity 17, the oil that squeezes in the oil pocket 18 will flow in the axis hole that changes core 15 by the corresponding with it oilhole 21 that unloads respectively, and further by blind hole 23, the through hole 24 of controlling rod 22, the oilhole 25 that unloads greatly that reaches on the input shaft flow back in the casing 1.
It is many more that controlling rod 22 is extracted out, unloads big more that oilhole 21 opens, and the speed of emptying is also fast more, and the oil pressure that squeeze in the oil pocket 18 will be low more.Arrive certain limit when low fuel pressure, begin to skid between middle gear ring 16 and the housing 14, thereby power can not exported by the housing 14 and the end cap 19 thereof of engaging and disengaging gear.
In the working procedure, the very a spot of oil in oil sucting cavity 17, the crowded oil pocket 18 can be by being disposed radially the through hole 31 on middle gear ring, to carrying out selflubricating between center tooth circle 17, the housing 14.
Shown in Fig. 4,5, the output engaging and disengaging gear is with the structure difference of input engaging and disengaging gear:
The housing 26 of output engaging and disengaging gear fixes as one with the output shaft of speed changer, and transmission output shaft is nested with on the controlling rod 27 of output engaging and disengaging gear.The commentaries on classics core 28 of output engaging and disengaging gear is that transmission shaft 29 fixes as one with the input shaft of output engaging and disengaging gear.
Other structures are identical with the input engaging and disengaging gear.
The output engaging and disengaging gear is identical with input engaging and disengaging gear working principle, and power all is to be input to the commentaries on classics core, finally exports by the housing and the end cap of engaging and disengaging gear.
As shown in Figure 1, each is imported a gear ring 30 all is installed on the engaging and disengaging gear end cap, and gear ring is provided with internal tooth, external tooth.Its internal tooth and the driving gear engagement that is installed in each transmission shaft 29 end; External tooth is connected with another gear ring of importing on engaging and disengaging gear by intermediate gear.
Above-mentioned each gear-driven velocity ratio is all inequality.Like this, can increase the gear of speed changer.As:
One retaining, power are by input shaft 2 inputs, by output shaft 5 outputs;
Two retainings, power are by input shaft 2 inputs, by output shaft 6 outputs;
Three retainings, power are by input shaft 2 inputs, by output shaft 7 outputs;
Four retainings, power are by input shaft 3 inputs, by output shaft 5 outputs;
Five retainings, power are by input shaft 3 inputs, by output shaft 6 outputs;
Six retainings, power are by input shaft 3 inputs, by output shaft 7 outputs;
Seven retainings, power are by input shaft 3 inputs, by output shaft 5 outputs;
Eight retainings, power are by input shaft 3 inputs, by output shaft 6 outputs;
Nine retainings, power are by input shaft 3 inputs, by output shaft 7 outputs.
Above-mentioned gear setting is not unique.
More if desired gears then can increase input shaft, input engaging and disengaging gear, input engaging and disengaging gear, output shaft and intermediate gear accordingly and get final product, and its principle is identical.
The conversion gear be exactly by control clutch device " from "/" closing " realize the controlling rod of i.e. operation input engaging and disengaging gear, output engaging and disengaging gear.
Output wheel among this embodiment on each output shaft 5,6,7 is sprocket wheel, and each sprocket wheel cooperates with same chain 32.The input sprocket 34 of middle output shaft 33 also cooperates with this chain 32, and middle output shaft is provided with reverse gear 35, forward gear gear 36.Total output shaft 37 is provided with an axially displaceable carrier wheel 38.When forward gear, forward gear gear 36 engagements on this carrier wheel 38 and the middle output shaft.In the time of need reversing gear, carrier wheel 38 moves axially along total output shaft 37, and finally is connected with reverse gear 35 on the middle output shaft by an intermediate speed pinion 39.Can realize 9 gears of forward gear like this, 9 gears reverse gear.
Wheel for inputting on each input shaft 2,3,4 among this embodiment is also driven by a total input shaft, can be that the chain connection also can be by modes such as gear connections, and mode of execution is not unique.
Be provided with oil sealing device between input shaft on the casing and the input engaging and disengaging gear housing; Also be provided with oil sealing device between the input shaft of output engaging and disengaging gear and the output engaging and disengaging gear housing, it is more reliable to guarantee that speed changer uses.
The utility model is not limited to above-mentioned mode of execution.
