本発明は質速矢動系に介在する操作部材の操作によって
変速を行うように構成された作業車の走行変速装置であ
って、詳しくは電動変速操作構造に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a traveling transmission device for a working vehicle configured to change gears by operating an operating member interposed in a mass speed arrow system. This invention relates to an electric shift operation structure.
E記変速装置には、シフトギヤを操作することによって
変速操作を行うものとシンクロメツシュ変速タイプのも

速操作を行うものとが一般に採用され!、又、変速装置
の電動変速操作構造には電動モータ等の直接駆動でシフ
トギアー、シンクロナイザリング等を操作するよう構成
したものが容易に考えられる。E-transmission devices generally employ two types of transmissions: one that performs a gear change operation by operating a shift gear, and the synchromesh transmission type that performs a gear change operation by operating a synchronizer ring. Furthermore, it is easy to think of an electric shift operation structure of a transmission device in which a shift gear, a synchronizer ring, etc. are operated by direct drive of an electric motor or the like.
しかし、シフトギア等を直接電動モータで駆動する場合
を考察すると、シフトギヤ等はその物自体が駆動力を栄
える構造のため操作を確実に行うことが必要であ抄、又
、操作力も比較的大きいことから電動モータの容量も大
きいものを用いなければならない問題があった。However, when considering the case where a shift gear etc. is directly driven by an electric motor, it is necessary to operate it reliably because the shift gear itself has a structure that generates driving force, and the operating force is also relatively large. Therefore, there was a problem in that an electric motor with a large capacity had to be used.
又、電動モータの大容量化は、外形、重量が増加するば
かりでなく駆動に要するパンテリ等、電源の大容量化を
招く等別の問題を生ずるものであった。Furthermore, increasing the capacity of the electric motor not only increases the external size and weight, but also causes other problems such as the need for a power supply, such as a power supply, which is required for driving the electric motor.
本発明はと記夾情に鑑みて為されたものであつて、比較
的小容量の電動モータによって変速操作を行い、しかも
、この変速操作が簡単に行えるよう構成した作業車の走
行変速装置を提供する点に目的を有する。The present invention has been made in view of the above-mentioned circumstances, and provides a traveling transmission device for a working vehicle that uses a relatively small-capacity electric motor to perform a speed change operation, and that is constructed so that the speed change operation can be performed easily. Be purposeful in what you offer.
本発明の特徴とするところは、変速装置に油圧操作式の

構成してある点にあり、その作用及び効果は次の通りで
ある。A feature of the present invention is that when a hydraulically operated transmission is adopted, the control pulse of the hydraulically operated multi-stage transmission mechanism is controlled by an electric motor whose forward and reverse operation is controlled by selecting a group of switches. The present invention is configured to perform multi-stage switching control, and its functions and effects are as follows.
つまり、E記の如く制御パルプを電動モータによって操
作することで変速が為されるため、電動モータで直接シ
フトギヤ等を操作する場合に比較して電動モータの駆動
力が小さくて済む。In other words, since the speed is changed by operating the control pulp with the electric motor as shown in E, the driving force of the electric motor can be smaller than when the electric motor directly operates the shift gear or the like.
又、電動モータの駆動がスイッチ群の選択操作によって
為されるため、任意の変速操作がスイッチを操作するだ
けの簡単な動作で行える。Furthermore, since the electric motor is driven by selecting a group of switches, any speed change operation can be performed simply by operating the switches.
[発明の効果]
従って、変速装置を油圧操作式に構成すると共に、制御

の軽い操作で簡単に行える走行変速装置が提供されるに
至った。[Effects of the Invention] Therefore, by configuring the transmission to be hydraulically operated and configuring the control pulp to be driven and operated by a motor linked to a group of switches, the electric motor l can be of relatively small capacity and the device can be improved. A traveling transmission device has been provided which does not require an increase in size, does not require changes to batteries, etc., and can easily carry out any desired speed change operation with a light operation of switches.
