Abstract

"TRANSMISSãO HIDROMECáNICA PARA TRATORES AGRìCOLAS". A Transmissão compreende uma haste de entrada (IS) que pode ser acoplada a um movimentador principal do trator e estende-se ao longo de primeira direção (x1) alinhada com a haste do movimentador principal e com uma haste (S1) da saída de potência do trator, uma haste de saída (OS), uma unidade hidrostática (HU) que inclui uma bomba (P) dirigida pela haste movimentadora principal e um motor (M) dirigido pela bomba (P), em que a bomba e o motor encontram-se em posição alinhada ao longo de segunda direção (x2) espaçada transversalmente para baixo a partir da primeira direção (x1), uma unidade de divisão de força de torção epicíclica (TSU), em posição alinhada com a unidade hidrostática (HU) e que inclui primeira e segunda hastes de entrada (S3) e (S4) acopladas ao motor (M) da unidade hidrostática (HU) e ao movimentador principal, respectivamente, e pelo menos primeira e segunda hastes de saída (S5) e (S6), em que as velocidades de rotação das primeira e segunda hastes de saída (S5) e (S6) variam, respectivamente, em primeira e segunda faixas (VD1-VD2, VC1-VC2, VD1-VD2, VB1VB2) adjacentes entre si, em alta velocidade e baixa velocidade, respectivamente, à medida que a velocidade de rotação da primeira haste de entrada (S3) varia entre valor máximo (rpma, rpmc) e valor mínimo (-rpmA, -rpmC), uma unidade de embreagem (CU), em posição alinhada com a unidade hidrostática (HU) e com a unidade de divisão de força de torção (TSU) e disposta para acoplar a haste de saída (OS) da transmissão seletivamente à primeira ou segunda haste de saída (S5, S6) da unidade de divisão de força de torção (TSU), de forma a fornecer um par de faixas de operação frontal ('transporte' e 'trabalho'), em alta e baixa velocidade, respectivamente, e uma unidade de reversão (RU) em posição alinhada com a unidade hidrostática (HU), a unidade de divisão de força de torção (TSU) e a unidade de embreagem (CU) e disposta para fornecer faixa de operação reversa ('reversa').
