Background technique
The speed-changing gear box of workers and peasants-12 tractor is generally used in China rural area, and this speed-changing gear box generally is used for the tractor of walk-behind type, also is useful on steering-wheel type articulated steering tractor.The shortcoming of this speed-changing gear box is to realize three outputs and the output of gear Complete Synchronization.The tractor gear gearbox that the output of some three outputs and gear Complete Synchronization also occurred at present, but the structure of this tractor gear gearbox and existing workers and peasants-12 tractor have very large difference, cause because of the not high problem that causes manufacture cost and maintenance cost all to increase substantially of Component versatility, and almost can't use existing and agricultural machinery and implement workers and peasants-12 tractor.
At present, we have retrieved some tractor gear gearbox open source literatures, for example:
1. Chinese patent application numbers 201120273840.7, open day on July 25th, 2012, the title microtractor speed-changing gear box of model utility, this application case discloses a kind of microtractor speed-changing gear box, it includes the secondary variable-speed shaft of accepting the power input, the driving of gear shift fork is housed on described secondary variable-speed shaft and cogs with the second axle and switch the change gear of engagement, switch by the gear on the change gear on it and described the second axle the main variable speed shaft that whole shift speed changes are completed in engagement, two front wheel driving shafts that connect with described main variable speed shaft by the gear transmission parts, described main variable speed shaft is by the gear on it and the 3rd power output gear engagement that is contained on the second axle, the 3rd power output gear is over against the 3rd power delivery outlet of gearbox casing, change gear on described secondary variable-speed shaft has two at least, and the axial switching stroke of these two change gear on described secondary variable-speed shaft is in respectively the both sides of described the 3rd power output gear.It has solved the rotating speed of front wheel output shaft and the rotating speed of facility output shaft keeps the microtractor speed-changing gear box of same ratio to make the high problem of maintenance cost at each gear.Its deficiency is: can't realize independent rear wheel drive; The auxiliary transmission complex structure supporting with it coordinates before and after gearshift needs, and causes and uses inconvenience.
2. Chinese patent application numbers 201120001615.8, open day on November 2nd, 2011, the transmission device of the single gearbox tractor of title bow steering type of model utility, this application case discloses the transmission device of the single gearbox tractor of a kind of bow steering type, be equipped with by shift fork (V3 on the pto＝power take-off (45) of its speed-changing gear box (4), V4, V2) these two change gear of the described front-wheel drive change gear of synchronous drive (453) and trailing wheel change gear (451) have two positions in the upper vibration of described pto＝power take-off (45) under the driving that drives switching driving lever (V1), one of them position is exactly that these two change gear are simultaneously to transmission shaft (6) transferring power of the forerunner's output shaft (47) that drives front driving wheel (5) and driving rear drive sprocket, one of them position is that these two change gear are only to transmission shaft (6) transferring power.Its deficiency is: need existing gearbox manufacturing mechanism, changes greatlyr, need to invest larger; Former supporting agricultural machinery and implement can't use, and client's purchase cost is high.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model provides a kind of and realizes that front double-shaft power is exported separately, front twin shaft and synchronous output gear gear synchronous dynamic output, front twin shaft and rear output gear with the output of gear synchronous dynamic, can use with existing workers and peasants-12 tractor agricultural machinery and implement three to synchronize the output gear gearbox.
For achieving the above object, the utility model is realized by following scheme:
A kind of three synchronous output gear gearboxes, comprise in speed-changing gear box the driving gear on the I axle of transferring power, II axle, III axle, IV axle, V axle, VI axle, VII axle and each axle thereof successively, described II axle is provided with synchronous output gear, the constant speed output gear can mesh with the change gear that is arranged on the VIII axle respectively, described synchronous output gear is connected with the II axle by bearing, described change gear is positioned at the medium position of VIII axle, and an end of described VIII axle also is provided with rear output gear.
In the utility model, as further improvement, described VIII axle is arranged on the casing of speed-changing gear box by bearing.
In the utility model, as further improvement, also be provided with setting sleeve on described VIII axle.
In the utility model, as further improvement, described synchronous output gear is synchronizeed with gear and is exported, and described constant speed output gear is not synchronizeed with gear and exported.
working principle of the present utility model: the utility model is at synchronous output gear of the other increase of facility output gear of the II axle of traditional workers and peasants-12 type tractor gear gearbox, increase a VIII axle at the rear portion of II axle simultaneously, the VIII axle is provided with output gear after a change gear and, can be respectively under the control of shift fork and the facility output gear, the synchronous output gear engagement that newly increases, when change gear with synchronize output gear when engagement, realize the rotating speed output of the rotating speed output of the rear output gear on the VIII axle and VII axle synchronously, when change gear and the engagement of facility output gear, realization is transmitted constant rotational speed to the rear output gear on the VIII axle.
The utlity model has following beneficial effect:
1. performance is powerful.The utility model can provide the gear of two forward and backward three synchronously to export by increasing synchronous output gear, can improve the travelling speed of tractor, improves lifting capacity, improves simultaneously the ability of reply complex road condition.
2. manufacture cost is relatively low.Housing structure of the present utility model and existing workers and peasants-12 tractor gear gearbox casing are similar, most of universal components, therefore original production line only needs a small amount of the change just can produce, and workman's training cost is low, upgrade cost is low, and manufacture cost is relatively low.
Easy to maintenance, maintenance cost is low.The component great majority of the workers and peasants on market-12 tractor can be used for keeping in repair the utility model, and it is convenient that the client buys rear later period maintenance.
