Inspection method for front axle of trailer axle

I told you that the trailer axle is divided into the front axle and the rear axle. Today I will continue to introduce the front axle. Here I will introduce some inspection methods when the front axle has problems, so that we don't have to worry about being cheated when we go to repair.

Test with I-beam tester

This method can accurately check the bending and twisting values of the front axle of the trailer axle in the vertical and horizontal planes. During the detection, the front axle needs to be fixed on the shelf, and then the steel plate seat and the kingpin hole need to be cleaned. Of course, the two locating pins, the locating holes of the steel plate seat and the base cushion block need to be placed on the plane of the steel plate seat, In this way, it can ensure the matching with the positioning hole, so as to ensure that there will not be some problems when using. Of course, there are still some precautions in the later stage.

Check with tester

The kingpin holes and spring seats at both ends of the trailer axle are used as the positioning inspection datum. Fix the instrument on the two leaf spring seats, insert a test rod into each of the two kingpin holes, operate the instrument to make the measuring head and the test rod coincide and contact, through different scales, reflect the position (angle) between the kingpin hole and the leaf spring seat and between the two leaf spring seats, check and judge to determine the deformation position and degree, Please refer to the instruction manual for the specific method and operation steps. Place the front axle on the two V-shaped irons on the flat plate and the level gauge on the leaf spring seat.

In fact, the measurement of the trailer axle must be accurate during the inspection, so as to ensure that there will be no problems during the measurement. I hope you can remember this, so as to avoid the data being untrue.
