苏联别拉斯自卸车装用的是别拉斯—540单级、四轮液力变扭器。有效直径Da=466毫米(表1和图1)。为了使这个液力变扭器能与各种发动机配合,在变扭器前面安装了一个机械式协调传动机构。装了这个机构以后,增加了传动系的重量,结构也显得复杂化,而且变扭系数下降了3～4％。 Soviet Union Buses Dump Truck equipped with the Balsamic -540 single-stage, four-wheel hydraulic torque converter. The effective diameter Da = 466 mm (Table 1 and Figure 1). In order to make this torque converter with a variety of engines, in front of the converter installed a mechanical coordination drive. After the installation of this agency, increasing the weight of the drivetrain, the structure also appears to be complicated, and the torsional coefficient decreased by 3 to 4%.
