Abstract

The invention relates to the technical field of automobile performance test tools and in particular to a tool for simulating the performance of a vehicle state measurement brake system. The tool comprises a torque sensor for detecting braking force, a speed sensor for detecting a simulated vehicle speed, a central controller, a front drive force assembly and a brake caliper assembly. The torque sensor, the speed sensor, the front drive force assembly and the brake caliper assembly are electrically connected to the central controller. The tool for simulating the performance of the vehicle statemeasurement brake system simulates braking by the brake caliper assembly so as to acquire parameters at a braking time, and compares the parameters with data of an inertia test bench, can meet the braking performance tests of various vehicle models and has a high test progress.

Description

technical field [0001] The invention relates to the technical field of automobile performance test tooling, in particular to a tool for simulating the state of a complete vehicle and measuring the performance of a braking system. Background technique [0002] At present, the measurement of the performance of the braking system in the industry is only for data collection on the real vehicle after the assembly of the vehicle is completed, and the required road conditions and instruments and equipment require the vehicle structure and measurement. This structure has the following disadvantages: the bench assembly cannot fully simulate the axle load transfer under the braking condition of the whole vehicle at present; the brake system component assemblies of different models need to be rebuilt; the brake system components need tooling samples Ensure product consistency; at the same time, the test system is complex and the experimental data is not accurate. [0003] Therefore, i...
