The new GB7258 regulation is about to be implemented, ""Liangshan Shenli" axle automatic adjustment arm installation and debugging video" is the first to see!
I believe that most card friends know the adjustment arm, so what is the working principle of the automatic adjustment arm? What are the advantages of the manual adjustment arm? Here, Xiaobian also popularizes it for everyone.
In fact, relative to the hand-arm, the self-adjusting arm adds a self-adjusting mechanism to the hand-arm. The self-adjusting mechanism senses the normal braking gap and the excess brake clearance after the brake pads are worn. After three aspects of the elastic deformation of the brake, the excess brake clearance after the brake pad wear is automatically recognized, and the excess brake clearance is adjusted.
Their ultimate goal, whether manual or automatic, is the same, except that the automatic adjustment arm does not require manual intervention to make the control gap more accurate. The automatic adjustment arm has the following main advantages:
First, the automatic adjustment arm can keep the gap between the brake pad and the brake drum constant, and can ensure the reliability of the brake to the greatest extent.
Third, it is no longer necessary to manually adjust the brake clearance, reduce the number of maintenance and repairs, improve the attendance rate of the vehicle, and always bid farewell to the brakes at the bottom of the drill.
