Embodiment
Shown in Figure 1 is a most preferred embodiment of the utility model.
As shown in Figure 1, the automotive power transmission system resultant fault diagnostic test platform of the most preferred embodiment of the utility model comprises engine (1) and engine electrically unit (2); Variator (3); Vehicle speed sensor (4), data acquisition system (DAS) (8), computing machine (9) and fault diagnosis teaching demonstrating board (10); It is characterized in that: rear portion and engine support that the support of said fault diagnosis teaching demonstrating board (10) stands on engine (1) constitute one; Said engine electrically unit (2), vehicle speed sensor (4) and tension-compression sensor (7) line all insert from said fault diagnosis teaching demonstrating board (10) back and detect jack; The outer front wheel driving shaft place that is connected on above the variator (3) of said dynamometer (5), said tension-compression sensor (7) is installed between dynamometer (5) shell and the bearing; Said dynamometer (5) is connected with computing machine (9) through switch board (6), realizes the Loading Control and the measurement of total system.
The automotive power transmission system resultant fault diagnostic test platform principle of work of present embodiment is following:
The ECU of engine (ECU) is installed to teaching plate central authorities.Each power lead, control line and the signal wire of engine circuit from the teaching backboard face access board is realized with the function of accomplishing ECU.
When platform experiment carries out deciding performance analysis, at first to find out the operating point that to simulate.Will experiment table be adjusted to the operating mode that will investigate, the signal that needs to gather has GES and torque signal.Through calculating, suffered drag loading in the time of can being converted into running car under the current vehicle speed to the GES that collects compares with the load value of torque sensor input; Deviate is converted into simulating signal output; Feed back in the controller exciting current of control dynamometer, and then the load of control dynamometer; Make its automatic adjustment, be stabilized to required operating mode.
Security: each sensor signal lines has all been carried out taxonomic revision, and inserts each calibrating terminal at the back from the teaching plate, makes front panel cleaner and tidier, and stand is safer;
