TESTING MACHINE FOR CAB SUSPENSION MOUNTING PART OF FREIGHT VEHICLE FOR OPTIMIZING DESIGN OF CAB SUSPENSION MOUNTER BY MEASURING WEAR OF CAB HINGE UNIT BY APPLYING TORSION AND ROTARY POWER OF CAB HINGE UNIT AND CORRESPONDENT SHOCK NOISE
TESTING MACHINE FOR CAB SUSPENSION MOUNTING PART OF FREIGHT VEHICLE FOR OPTIMIZING DESIGN OF CAB SUSPENSION MOUNTER BY MEASURING WEAR OF CAB HINGE UNIT BY APPLYING TORSION AND ROTARY POWER OF CAB HINGE UNIT AND CORRESPONDENT SHOCK NOISE
PURPOSE: A testing machine for a cab suspension mounting part of a freight vehicle is provided to measure accurately the wear of inner and outer cases combined with a hinge shaft and to secure a precise design value of an actual vehicle by applying power of a condition same as an actual vehicle traveling to the hinge shaft at a frame and suspension mounting part comprising the actual vehicle. CONSTITUTION: A testing machine for a cab suspension mounting part of a freight vehicle is composed of a hinge bracket(1) positioned higher than a rear side of a frame and a suspension mounting part(A) of an actual vehicle; a plate(2) installed to rotate about the hinge bracket and closely contacted with the suspension mounting part at the bottom side of one end to generate rotary power at a hinge shaft in rotating the plate; a weight material(3) installed in the rear end of the plate to have weight same as a cab to be tested; and a cylinder(4) disposed at the front end of the plate symmetrically to the weight material to rotate the plate.
