Therefore, before going into operation to brake system of car assembling or research and development, brake system and the pipeline of reply automobile carry out fail-test.
Summary of the invention
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of reliability test for brake system of car and pipeline, real vehicle can be departed from completely and separately fail-test is carried out to brake system and pipeline, for simulating the durable reliability verifying whole brake system and pipeline under real vehicle state.
To achieve these goals, the technical solution of the utility model: a kind of reliability test for brake system of car and pipeline, it comprises by the master cylinder to be measured containing brake oil, the vacuum boost system that vacuum booster to be measured and the brake pedal to be measured controlling this vacuum booster to be measured form, and the brake combination valve to be measured to be connected with described master cylinder pipeline to be measured, wherein, described brake combination valve to be measured is communicated to four brake discs for braking four simulating wheels respectively by four pipeline correspondences, and be equipped with on each pipeline and described four brake discs tensimeter one to one, described vacuum booster to be measured is circumscribed with vacuum generator, described brake pedal to be measured is connected with the cylinder can braking this brake pedal to be measured.
Further, described four simulating wheels are driven one by one by four three phase electric machines.
Further, described brake combination valve to be measured is provided with braking warning lamp.
Further, also include controller, this controller is electrically connected with the solenoid valve controlling described cylinder.
The beneficial effects of the utility model: started by cylinder and depress brake pedal to be measured, the brake oil in master cylinder to be measured is driven to flow to brake combination valve to be measured, carry out confession oil brake by brake combination valve to be measured to four brake discs, can realize carrying out the durable simulation test of reliability to all brake system and pipeline.This device is swift and convenient to operate and economical and practical, can depart from real vehicle completely and carry out fail-test to brake system and pipeline separately, for simulating the durable reliability verifying whole brake system and pipeline under real vehicle state.
