A three-axis steering performance test bench for testing automotive steering system assemblies

Abstract

This utility model discloses a three-axis steering performance test bench for testing automotive steering gear assemblies, including a workbench, a control cabinet installed at the top edge of the workbench, a torque sensor installed on the top of the workbench, a rotating rod rotatably connected inside the torque sensor, a drive motor installed at one end of the rotating rod, a steering wheel installed on one side of the torque sensor, and a lubrication assembly installed on the rotating rod. In this utility model, when the rotating rod rotates, it drives the rotating block to press the movable plate downwards, the movable plate drives the movable rod to move the piston plate, and the piston plate discharges the lubricating oil in the oil reservoir into the lubrication sleeve through the oil drain pipe. When the rotating rod returns to its original position, the spring will cause the piston plate to return to its original position, so the oil reservoir will be replenished with new lubricating oil through the oil inlet pipe. In this way, when the rotating rod rotates, lubricating oil will be automatically discharged into the lubrication sleeve to lubricate and protect the rotating rod, so that the operator does not need to manually replenish the lubricating oil for the rotating rod.
