Abstract:
(EN) Internal structures of a transmission and a clutch are simplified. A drive shaft is drivingly connected to an engine via a clutch, a branch transmission body is provided on the drive shaft, and a traveling system transmission mechanism and a PTO system transmission mechanism are parallelly drivingly connected to the branch transmission body. By this, drive shafts can be formed as a single shaft, and the clutch can be formed also as a single clutch structure. As a consequence, structures of the insides of a transmission and the clutch are simplified and downsized, which reduces production costs. Further, when the clutch is disengaged, power transmission to both transmission systems of the traveling system transmission mechanism and the PTO system transmission mechanism can be shutoff at the same time, and this improves operability.
(FR) L’invention a pour but de simplifier les structures internes d’une transmission et d’un embrayage. Un arbre moteur est raccordé de façon motrice à un moteur via un embrayage ; un corps de transmission de dérivation est installé sur l’arbre moteur ; un mécanisme de transmission de déplacement et un mécanisme de transmission d’un système de prise de force sont raccordés de façon motrice en parallèle au corps de transmission de dérivation. Ceci permet à des arbres moteurs d’être constitués en un arbre unique, et à l’embrayage d’avoir une structure d’embrayage unique également. Les structures internes d’une transmission et d’un embrayage sont ainsi simplifiées et leurs dimensions sont réduites, d’où une réduction de leurs coûts de production. En outre, quand l’embrayage est libéré, la transmission de puissance aux deux systèmes de transmission du mécanisme de transmission de système de déplacement et au mécanisme de transmission du système de prise de force peut être arrêtée simultanément, ce qui améliore l’opérabilité.
(JA)  ミッション部内とクラッチ部内の構造を簡易化することを課題とする。  そこで、本発明では、エンジンにクラッチを介して駆動軸を連動連結し、同駆動軸に分岐伝動体を設けて、同分岐伝動体に走行系伝動機構とPTO系伝動機構とを並列的に連動連結した。従って、駆動軸を単一軸となすことができると共に、クラッチもシングルクラッチ構造となすことができて、ミッション部内とクラッチ部内の構造を簡易化することができると共に小型化することができて、製造コストも低減化することができる。しかも、クラッチを切断動作させることにより、走行系伝動機構とPTO系伝動機構の両方の伝動系への動力伝達を同時に切断することができて、操作性を向上させることができる。
