Car Brake Pad Dynamometer – Type B
Application:
The brake is one of the important components for safe driving of a car, and its performance has a significant impact on the driving safety and power performance of the car. Usually, brake performance is tested according to the testing standards set by authoritative institutions. The general testing methods include small sample testing and inertial bench testing. Small sample tests are used to simulate brake dimensions and shapes, resulting in low accuracy but relatively low cost. They are commonly used for grading friction materials, quality control, and the development of new products.
The brake dynamometer is the most authoritative test in brake quality inspection, which can truly reflect the working characteristics of the brake and has gradually become the mainstream of brake quality inspection. It can test brake systems in a controlled environment that mirrors the real world.
The Dynamometer test of automobile brakes is a simulation of the braking process of automobiles, which tests the braking efficiency, thermal stability, lining wear, and strength of the brakes through bench tests. The current universal method in the world is to simulate the braking conditions of a brake assembly using mechanical inertia or electrical inertia, in order to test its various performance. This split type dynamometer is designed for brake testing of passenger cars.
Advantages:
1.1 The host is separated from the test platform to minimize the impact of host vibration and noise on the test.
1.2 The flywheel is positioned with the conical surface of the main shaft, which is convenient for disassembly and stable operation.
1.3 The bench adopts servo electric cylinder to drive the brake master cylinder. The system operates stably and reliably with high pressure control accuracy.
1.4 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
1.5 Executable test standards: AK-Master, SAE J2522, ECE R90, JASO C406, ISO 26867, GB-T34007-2017 test and so on.
