本発明は、トラクタの変速を行なうに際し、トラクタの
定行を停止させることなく変速を行ない。DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention changes the speed of a tractor without stopping the tractor from moving normally.
かつ、多くの変速段数を得るトラクタの変速装置に関す
るものである。The present invention also relates to a tractor transmission that provides a large number of gears.
発明の技術的背景及びその問題点
従来、プラウ等の牽引作業機を牽引する農用トラクタに
おいては１作業中に変速操作を行なう場合、トラクタの
走行を一旦停止させて変速操作を行ない、変速拠作後に
トラクタを再スタートさせている。しかし、牽引負荷が
大きい場合には、車軸がスリップして再スター１−が不
可能となることがある。Technical Background of the Invention and its Problems Conventionally, in agricultural tractors that pull tractors such as plows, when changing gears during one operation, the tractor must first stop traveling and then change gears. The tractor was then restarted. However, if the traction load is large, the axle may slip, making restart 1- impossible.
そこで、変速装置にシンクロメツシュ機構を用いてトラ
クタの走行を停止させることなく走行中に変速操作を行
なうことが考えられるが、この場合においても変速操作
時には走行用クラッチを一旦切らなければならず、牽引
負荷が大きい場合にはクラッチを切ることによってトラ
クタが停止してしまう。Therefore, it is possible to use a synchronized mesh mechanism in the transmission to change gears while the tractor is running without stopping the tractor, but even in this case, the traveling clutch must be disengaged once when changing gears. If the traction load is large, disengaging the clutch will cause the tractor to stop.
変速操作時におけるトラゲタの走行停止を確実に防止し
うる変速装置としては、各変速ギヤに湿式多板クラッチ
を設けて油圧力により各クラッチを選択的に断続させて
変速を行なうものがある。As a transmission device that can reliably prevent the Trageta from stopping during a gear shift operation, there is one in which a wet multi-disc clutch is provided in each gear and the gears are selectively engaged and engaged using hydraulic pressure.
しかし、この変速装置は油圧湿式多板クラッチを用いる
ため、構造が複雑になるとともに故障も多く、また、油
圧湿式多板クラッチに多くのスペースを必要とするため
に変速段数を多くとれない等の欠点がある。However, since this transmission uses a hydraulic wet multi-disc clutch, the structure is complex and there are many failures, and the hydraulic wet multi-disc clutch requires a large amount of space, making it difficult to provide a large number of gears. There are drawbacks.
また、変速操作時におけるトラクタの走行停止りを確実
に防止しつる他の変速装置としては、各種の無段変速装
置があるが、いずれも動力伝達効率が十分てないために
高置６４ｊの牽引作業には適さず、コストが高いという
欠点がある。In addition, there are various continuously variable transmissions that reliably prevent the tractor from stopping when changing gears, but none of them have sufficient power transmission efficiency, so they cannot be used for towing at elevated locations. It has the drawbacks of being unsuitable for work and high cost.
発明の目的
本発明は、このような点に鑑みなされたもので、簡単な

ペース内で多くの変速段数を得ることを目的とする。Purpose of the Invention The present invention has been made in view of the above points, and uses a simple synchronized mesh mechanism to simplify the structure, and furthermore, even when the traction load is large, it is possible to prevent the tractor from stopping when changing gears. The purpose of the present invention is to reliably prevent this and obtain a large number of gears in a small space.

ある。SUMMARY OF THE INVENTION The present invention provides a clutch that can selectively connect and disconnect power from an engine as two output systems, connects two speed change gear devices with a synchronized mesh structure to the clutch, and connects a plurality of transmission gears to the clutch. The output shaft to which the passive gear is fixed is always connected to two speed change gear devices, and during normal work, power is transmitted from the engine to the output shaft through one speed change gear device, and it is in a free state during speed change operations. After the shift operation is completed, the clutch is engaged and engaged to free the other shift gear device that was transmitting power to the output shaft, and the shift operation is carried out. The power is transmitted to the output shaft through the other gear change gear device, which prevents the tractor from stopping during the gear change operation.
By using different gear ratios of the device, a large number of gears can be obtained within a small space.

For example, when shifting from the i-speed running state to the 2nd speed, the connecting member 18 is operated by soft operation to connect the loose-fit gear 12 to the intermediate shaft 7 so as to rotate integrally therewith. By disengaging the clutch 25 and connecting the clutch 27 after this shift operation is completed, the power from the engine 20 is
Power transmission shaft 28, output gear 30, input gear 22. The power is transmitted from the power transmission system consisting of the intermediate shaft 7 to the output 1i1111 via the YT fitting gear 12 and the passive gear 2, and a shift to the second speed is performed. In this way, the gears can be changed without stopping the tractor, and what's more.

の手順で２速から３速に変速する。Since the disengagement of the clutch 25 and the engagement of the clutch 27 are carried out continuously and instantaneously, even when a large traction load is applied to the work equipment connected to the tractor, the disengagement of the clutch 25 may cause the tractor to disengage. This prevents the running from stopping. Note that when shifting from 1.1a to 3rd speed, first shift to 2nd speed as in the above procedure, and then shift from 2nd to 3rd speed in the same manner.
