Fatigue test device for front axle steering system

Abstract

A front axle steering system fatigue test device disclosed by the present invention comprises a test bench, the edge of the test bench is fixedly connected with an edge frame, the two sides of the edge frame are fixedly provided with wheel disc limiting members, and one side of the top of the edge frame is rotatably connected with a test driving member; a pull rod moving groove is formed in one side of the top of the test bed, rocker arm moving grooves are formed in the two ends of the pull rod moving groove, and a pull rod test piece is fixedly installed on the other side of the top of the edge frame. During use, power input is performed on the whole front axle steering system, the wheel disc limiting pieces are used for pushing and limiting the two steering wheel discs, and the stability of the whole position posture of the front axle steering system in the testing process is improved; by arranging the pull rod test piece, the pull rod replacement plate and other structures, independent detection of the transmission pull rod and the trapezoidal rocker arm is achieved, and detection is more visual and convenient.

Description

technical field [0001] The invention relates to the related technical field of front axle test equipment, in particular to a front axle steering system fatigue test device. Background technique [0002] The steering system is a series of devices that change or maintain the direction of driving or reversing according to the driver's wishes. [0003] During the production process of the front axle steering system, it needs to be tested for fatigue detection. like figure 1 An existing fatigue test device for the front axle steering system is shown. During the test, the front axle steering system is fixed through the bearing plate, and the driving column is used to drive its movement. This installation and fixing method is easy to make The steering wheels at both ends lack sufficient adjustment space, which makes the adjustment and installation during the test inconvenient; at the same time, the existing front axle steering system fatigue test device generally can only test th...

Problems solved by technology

like figure 1 An existing fatigue test device for the front axle steering system is shown. During the test, the front axle steering system is fixed through the bearing plate, and the driving column is used to drive its movement. This installation and fixing method is easy to make The steering wheels at both ends lack sufficient adjustment space, which makes the adjustment and installation during the test inconvenient; at the same time, the existing front axle steering system fatigue test device generally can only test the front axle steering system as a whole, and cannot individually test individual components. Difficult to meet the needs of use
