Mechanism for measuring dynamic strength of automobile front axle rocker arm

A structure used to test dynamic intensity of protocerebral rocker of a car can at the same time imitate the rigidity restriction of axial direction linearity and radial nonlinearity. One side of anti-yaw fastening device imitate rigidity restriction of axial direction linearity, the other side is separately linked to two triangle crank-spring armor plate agency, anti-yaw fastening device drives one triangle crank agency to do rotary motion clockwise or drives the other one to do rotary motion counterclockwise. The rolling axletree in a climax of the triangle crank component does vertical motion along the top bump of spring panel on the taper, so it produces different acting force and actuating arm acting on spring panel on the taper to result the anti-yaw fastening device to produce nonlinearity rigidity restriction counterforce consisting with rocker radial rigidity property, the back shaft supporting restriction of protocerebral rocker is in the anti-yaw fastening device, so it really re-creates the working state of protocerebral rocker of a car and promote the reliability of simulation test.
