Abstract

"MECANISMO DE TRAVAMENTO DA BARRA DE TRAçãO EXTENSìVEL EM MáQUINAS AGRìCOLAS". Trata-se de um aperfeiçoamento no mecanismo de travamento da barra de tração. Na sua posição de trabalho da máquina (retraída), este mecanismo compõem-se de um elemento em forma de L articulado no seu vértice à parte fixa da barra de tração. Em uma de suas extremidades apresenta um engate, em forma de gatilho, que pode se acoplar a um encosto ou batente localizado na parte extensível da barra de tração. Na outra extremidade está acoplado à haste de um cilindro hidráulico disposto paralelamente à barra de tração. A outra extremidade do cilindro hidráulico é articulada na parte fixa (externa) na barra de tração extensível. Na posição de transporte, a barra de tração central está estendida, e as duas barras laterais das secções laterais paralelas a ela. Assim sendo as barras laterais é que transmitem o esforço de tração proporcionado pelo trator realizando assim o travamento da barra de tração para essa posição."Drawbar locking mechanism extensible on agricultural machines". This is an improvement in the drawbar locking mechanism. In its (retracted) machine working position, this mechanism consists of an L-shaped element hinged at its apex to the fixed part of the drawbar. At one end it has a trigger-shaped coupling that can be coupled to a backrest or anvil located on the extendable part of the drawbar. At the other end is coupled to the rod of a hydraulic cylinder arranged parallel to the drawbar. The other end of the hydraulic cylinder is hinged to the fixed (outer) part of the extendable drawbar. In transport position, the center drawbar is extended, and the two sidebars of the side sections parallel to it. Thus the sidebars transmit the tractive effort provided by the tractor thus locking the drawbar to that position.
