Description
Technical field
The present invention is about the method for a kind of steering gear testing table automatic control system and control steering gear test thereof, especially a kind ofly can control the steering gear testing table carries out long duration test to the steering gear of different model steering gear testing table automatic control system and corresponding autocontrol method thereof automatically.
Background technology
Along with increasing people begins to have the private automobile, the security performance of automobile is also paid close attention to by people more and more.Therefore, automobile is put goods on the market sell before, must carry out various performance tests to each parts, the assembly of automobile, so that possible potential safety hazard is reduced to bottom line.So people promptly develop various checks, testing apparatus, to carry out corresponding performance test at different parts.
Relevant prior art is U.S. Pat P6 for example, and 305,217, it is about a kind of " automobile-used diagnostic tester ", whether the various parts that are mainly used in testing automobile can normally carry out every function after the automobile assembling is finished.This tester directly is contained on the automobile steering wheel, receives fault-signal from automobile the corresponding interface, while can drive, test.
China utility model patent ZL02220571.3 then discloses a kind of multi-purpose vehicle(MPV) steering assembly testing table, and actual steering resistance and damping that it can simulated automotive realize that varying load loads.The disclosed testing table essence of this patent is that automobile steering device testing table four is formed the charger of one of (drive unit, charger, control device, proving installation) greatly, be characterized in to realize that varying load loads, so that power steering stgear and manual steering gear are tested accordingly.
