Abstract

dispositivo de acoplamento para um braço inferior de um sistema de elevação de três pontos. a presente invenção se relaciona com um dispositivo de acoplamento (10) para um braço inferior (24) de um sistema de elevação de três pontos, compreendendo um corpo de acoplamento (12) com um gancho de engate (14) para receber um elemento de acoplamento (18) complementar a uma área de fixação (16) do gancho de engate (14) ao longo de uma direção de recepção (20) definida, e um mecanismo de bloqueio (28) com um trinco de bloqueio (30) que é empurrado sob a ação de uma força de mola para uma posição de bloqueio (32), bloqueando o gancho de engate (14), de modo a que um elemento de acoplamento (18) a ser recebido pela área de fixação (16) possa ser bloqueado no gancho de engate (14). neste contexto, o perno de bloqueio (30) é montado longitudinalmente e de forma deslocável numa guia deslizante (34) prevista no corpo do acoplamento (12), de modo a que possa ser desviado da posição de bloqueio (32) exclusivamente perpendicularmente à direção de recepção (20) definida, liberando a área de fixação (16), em que o perno de bloqueio (30) localizado na posição de bloqueio (32) se projeta de forma bloqueante em mais da metade para além da área de fixação (16) na direção de recepção (20) definida.
