Embodiment 1

[0030] In order to improve the accuracy of the test, a sensor with a measuring range smaller than the maximum force that the brake regulator suffered during the experiment was selected. During the test of the brake regulator, the brake regulator will be tested for starting force. At this time, a force of about 4000N is applied to the brake regulator, and the brake regulator is connected to the force testing device through the connecting device. When the brake regulator is under force, the force first acts on the load-bearing plate 2 through the action of the connecting device. At this time, the load-bearing plate 2 is stressed, and the force is transmitted from the load-bearing plate 2 to the butterfly spring 5, which is then transmitted to the guide rod. 4 and force sensor 6, when testing the starting force, since the starting force is about 4000N, the deformation of the combined butterfly spring 5 is smaller than the gap between the middle parts of the four adjusting rods 3 a...

Abstract

The invention discloses a stress testing device for a brake adjuster, and belongs to the technical field of stress testing of the brake adjuster; the invention aims to provide a device for testing a real-time stress condition and a starting force on the brake adjuster. The device comprises a bracket, a bearing plate, an adjusting rod, a guiding rod, a belleville spring and a force sensor. The device is structurally characterized in that the bearing plate is arranged in front of the bracket, two guiding rod locating holes are arranged in the bearing plate, and adjusting rod locating holes are arranged in four corners on the bearing plate; the adjusting rod, the force sensor, the guiding rod and the belleville spring are arranged between the bearing plate and the bracket; the belleville spring is sleeved on the guiding rod, a front section of the guiding rod is sleeved in the guiding rod locating holes; the force sensor is fixed on the bracket, and is arranged right behind the guiding rod and is in close contact with the guiding rod; the adjusting rod comprises a front part, a middle part and a rear part, wherein the front part is sleeved in the adjusting rod locating holes in the bearing plate and the rear part is fixed with the bracket; the device is mainly applied to the stress testing of the brake adjuster.

Description

technical field [0001] The invention relates to a force testing device for a brake regulator, which belongs to the technical field of force testing for a brake regulator. Background technique [0002] The brake shoe clearance adjuster (referred to as the brake adjuster) is an important part of the basic braking device of the railway vehicle. Within the specified range, the necessary braking force of the vehicle is ensured, the reliability of train driving safety is improved, and the impact caused by uneven braking force can be reduced at the same time. Whether the brake regulator can normally elongate under certain stress conditions is of great significance to ensure train safety, but at present there is no suitable device for testing the stress situation of the brake regulator in new build and maintenance tests. Contents of the invention [0003] In view of the fact that there is currently no suitable device for testing the force of the brake regulator in the new manufac...
