1. Application:
The brake dynamometer can realize the braking performance appraisal and evaluation test of various types of Passenger cars and commercial vehicles, as well as the braking performance test of automobile brake assemblies or braking components. The device can simulate the real driving conditions and the braking effect under various extreme conditions to the greatest extent, so as to test the real braking effect of the brake pads.
2. Product Detail:
This brake electric simulated inertia test-bed takes the horn brake assembly as the test object, and the mechanical inertia and electric inertia are mixed to simulate the inertia loading, which is used to complete the brake performance test.
The bench adopts split structure. The sliding table and flywheel set are separated and connected by universal transmission shaft in the middle, the test specimen adopts the brake assembly, which can ensure the parallelism and perpendicularity of the brake and the brake disc, and make the experimental data more accurate.
The host machine and test platform adopt the similar bench technology of German Schenck company, and there is no foundation installation method, which not only facilitates the installation of equipment, but also saves a large amount of concrete foundation cost for users. The damping foundation adopted can effectively prevent the influence of environmental vibration.
The bench software can execute various existing standards, and is ergonomically friendly. Users can compile test programs by themselves. The special noise test system can run independently without relying on the main program, which is convenient for management.
