    • A synchronising system (1) is described, in particular for trucks for transporting motor vehicles and trailers, comprising at least one first and one second hydraulic motors (M1, M2) arranged in series along an hydraulic feeding circuit (L) by which they are actuated, at least first detection means (R1) of a rotation speed of the first motor (Ml) and at least second detection means (R2) of a rotation speed of the second motor (M2), the detection means (R1, R2) cooperating with the control and managing means (C), to detect differences in rotation speed between the first motor (M1) and the second motor (M2), such hydraulic feeding circuit (L) comprising at least one first by-passing line (B1) of the first motor (M1) connected with the hydraulic feeding circuit (L) upstream of the first motor (Ml) by interposing first switching means between the first by-passing line (B1) and the hydraulic feeding circuit (L), and at least one second by-passing line (B2) of the second motor (M2) connected to the hydraulic feeding circuit (L) upstream of the second motor (M2) by interposing second switching means between the second by-passing line (B2) and the hydraulic feeding circuit (L), the first and second switching means being actuated by the control and managing means (C).
    • 一种同步系统(1),特别是用于运输机动车辆和拖车的卡车,包括至少一个第一和第二液压马达(M1,M2),它们沿液压供给回路(L)串联布置, 所述第一电动机(M1)的旋转速度的至少第一检测装置(R1)和所述第二电动机(M2)的转速的至少第二检测装置(R2),所述检测装置(R1,R2) 与控制和管理装置(C)配合,检测第一电动机(M1)和第二电动机(M2)之间的转速差,这样的液压供给电路(L)包括至少一个第一旁通线(B1 )通过在第一旁路线(B1)和液压供给回路(L)之间插入第一切换装置,与第一马达(M1)上游的液压供给回路(L)连接的第一马达(M1) 所述第二电动机(M2)的至少一个第二旁路线(B2)连接 通过在第二旁路线(B2)和液压供给回路(L)之间插入第二切换机构而将第二马达(M2)的上游的液压供给回路(L) 控制和管理手段(C)。
