The invention relates to a testboard for testing a bogie of a railway vehicle. The testboard comprises a load applying device (100) for generating linear acting force on the bogie to be tested. The load applying device (100) includes a hydraulic cylinder (110) having a piston rod (114). The hydraulic cylinder (110) is a double-acting hydraulic cylinder, the cylinder chamber of which is pressurized with hydraulic fluid by a bi-directional axial plunger pump (140). The test bench also includes a transmission (120) for transmitting a force to the bogie, the transmission (120) being operably connected to one end of the piston rod (114).
本发明涉及一种用于测试轨道车辆转向架的测试台,包括用于对待测转向架产生线性作用力的载荷施加装置(100)。载荷施加装置(100)包括具有活塞杆(114)的液压缸(110)。液压缸(110)是双作用液压缸,液压缸的缸室由双向轴向柱塞泵(140)用液压流体加压。测试台还包括用于将作用力传递到转向架的传动装置(120),所述传动装置(120)可操作地连接到活塞杆(114)的一端。
