Technical field
The utility model relates to the detection testing table of auto parts and components, electric powered steering Function detection testing table specifically.
Background technology
Qualified motorcar electric steering gear should be satisfied: when by the different speed of a motor vehicle hand hand rotation steering wheel, rotation process should be level and smooth, and no clamping stagnation does not have obviously vibration, and the inertial delay phenomenon does not extremely have during arbitrarily angled stopping.In the prior art, not having a kind of testing table to carry out perfect functions to the motorcar electric steering gear detects, it is perfect inadequately to make that whole piece detects assembly line, the disqualification rate of product is high, the first-time qualification rate of product can not get improving, the zero kilometer fault can not get reducing, and the performance of product can not get promoting.
Summary of the invention
Technical problem to be solved in the utility model is: the shortcoming at above prior art exists, a kind of product first-time qualification rate that improves is proposed, and reduce the zero kilometer fault, can promote the electric powered steering Function detection testing table of properties of product.
The technical scheme that the utility model solves above technical matters is:
Electric powered steering Function detection testing table, comprise that bearing circle, steering gear, spring load case and motor, bearing circle links to each other with steering gear, steering gear loads case with spring and links to each other, also comprise torque sensor, EPS controller, simulation vehicle speed signal transmitter and accumulator, torque sensor links to each other with bearing circle, and the output of torque sensor connects the input of EPS controller, the output of simulation vehicle speed signal transmitter connects the input of EPS controller, and the output of EPS controller connects the input of motor.
When steering wheel rotates, torque signal and turn signal that torque sensor will detect on the steering wheel are passed to ECU, ECU accepts vehicle speed signal simultaneously, determine the basic power-assisted electric current of assist motor in view of the above, also generate motor inertia compensation electric current and damping compensation electric current then, total current is as the motor target current, and the motor-drive circuit by ECU inside carries out moment of torsion control to motor.
The utility model has the advantages that: the utility model can be realized return function by in the process of different speed of a motor vehicle hand rotation steering wheels; Can under the different speed of a motor vehicle of test, detect the motor maximum current of maximum power-assisted; Can check mechanical friction and any possible mechanical resistance that electric power-assisted steering apparatus rotates under power-off and on-state under light condition, rotational resistance torque and fluctuation thereof should be steady.The utility model can improve the product first-time qualification rate, reduces the zero kilometer fault, is the performance boost of product simultaneously, and the means of looking for problem and problem analysis are provided.
