Further, the clutch pressure signal includes a clutch pressure acquisition signal, the parking position signal, the shift fork position signal and the clutch actual pressure signal can be obtained by acquiring related data through a parking position sensor and a shift fork position sensor which are arranged on a transmission on the standard transmission 100 and a pressure sensor which is arranged on the clutch, the parking position sensor, the shift fork position sensor and the pressure sensor further transmit the parking position signal, the shift fork position signal and the clutch actual pressure signal which are respectively acquired to the signal conditioning module 14 and then the signal conditioning module 14 to the analog quantity acquisition module 23, the analog quantity feedback device 24 can judge whether the parking is in place according to the position feedback quantity acquired by the parking position sensor, and judge the regulation and control of the clutch according to the clutch pressure feedback quantity acquired by the pressure sensor, and determining a gear signal of the target transmission according to the position of the shifting fork and the pressure of the clutch or the rotating speed ratio of the input rotating speed and the output rotating speed of the transmission. In a preferred embodiment provided by the present invention, the actual gear position of the transmission is determined by checking a ratio of the input rotation speed of the transmission measured by the rotation speed measuring unit 102a to the output rotation speed of the transmission measured by the output rotation speed measuring unit 102b in the analog quantity acquisition module 23, so as to ensure that the gear locking is completed.
As the actual gear condition of the transmission is determined by the speed ratio, the actual shifting fork position of the gear of the transmission can be judged according to the speed ratio. In the case where the connection portion of the target transmission 100 and the stage motor does not slip, the input rotation speed may be understood as the drive shaft rotation speed of the target transmission or the drive rotation speed transmitted from the control device 21 to the analog quantity feedback device 24.
Furthermore, in a specific embodiment provided by the present invention, the clutch is a dual clutch, and the direct drive solenoid valve 105 provides a certain pressure to the clutch through a current provided by a voltage, the output pressure acts on a clutch pressure plate to transmit a torque (friction) to drive the clutch driving shaft to rotate, at this time, the signal conditioning module 14 may obtain an actual rotating speed of the clutch by way of pulse counting, and transmit a clutch actual rotating speed signal to the analog quantity acquisition module 23, and the analog quantity feedback device 24 may determine a state of the clutch (slipping or pressing or separating) according to a difference between the actual rotating speed of the clutch transmitted by the analog quantity acquisition module 23 and the input rotating speed. In detail, during gear shifting, due to the fact that the pressure value of the clutch is not enough, the actual rotating speed of the clutch and the input rotating speed have a difference value, and the clutch is in a slipping state. After the gear shifting is successful, if the clutch is not operated by mistake, the pressure value of the clutch is enough, the actual rotating speed of the clutch is consistent with the actual rotating speed, namely the difference value is zero, and the clutch is in a compression state; if the two clutches are simultaneously combined due to misoperation, the rotating speed of the clutches is different from the input rotating speed, so that the clutches are worn or even burnt; in neutral, the two clutches are not engaged and the clutches are disengaged. In the present invention, the clutch pressure acquisition signal needs to be calibrated in relation to the output pressure and voltage, and is stored in the control device 21 in advance.
More specifically, the clutch pressure signal includes a clutch actual pressure signal; since the clutch pressure corresponds to the clutch rotation speed, the analog feedback device 24 can obtain the actual clutch pressure signal in the actual process through the actual clutch rotation speed input in the analog acquisition module 23 and the corresponding relationship between the clutch pressure and the clutch rotation speed, and further feed back the regulation and control of the clutch by combining the clutch pressure acquisition signal obtained by the analog acquisition module 23.
In a specific embodiment provided by the present invention, the clutch includes an odd clutch and an even clutch, and the clutch pressure collecting signal includes an odd clutch pressure collecting signal corresponding to an actual rotating speed of the odd clutch output by the odd clutch and an even clutch pressure collecting signal corresponding to an actual rotating speed of the even clutch output by the even clutch. It can be understood that when the direct-drive solenoid valve 105 is combined with the odd-numbered clutch, the state of the odd-numbered clutch can be judged according to the same principle, namely according to the difference value between the actual rotating speed and the input rotating speed of the odd-numbered clutch, and the regulation and control of the clutch can be fed back according to the actual rotating speed of the odd-numbered clutch, the corresponding relation between the pressure of the odd-numbered clutch and the rotating speed of the odd-numbered clutch, and the collected pressure collecting signal of the odd-numbered clutch. Likewise, when the direct-drive solenoid valve 105 is combined with the even-numbered clutch, reference may be made to the specific principle of combination with the odd-numbered clutch, and the description thereof is omitted.
The analog quantity acquisition module 23 provided by the invention can avoid the problems that the signal transmitted in the actual mapping test process is interfered and the signal magnitude is not matched with the acquisition equipment, so as to provide high-quality signal acquisition. It is understood that the dual clutch transmission gantry-to-map test system provided by the present invention may not include the analog acquisition module 23.
In the present invention, the control device 21 and the analog feedback device 24 may be computer systems, that is, the control device 21 is a control computer, and the analog feedback device 24 is an acquisition feedback computer, but in other embodiments, the control device 21 may also be other control systems such as a PLC, and is not limited specifically.
The dual-clutch transmission bench mapping test system further comprises an incubator 27 for testing the low-temperature performance of the targeted transmission 100, a temperature sensor for measuring the temperature of the incubator is arranged in the incubator 27, and the temperature sensor transmits a measured temperature signal of the incubator to the analog feedback device 24 through the control device 21. That is, the control device 21 according to the present invention transmits the acquired rotation angle, driving rotation speed, driving torque, and oven temperature of the gantry motor to the analog feedback device 24, so as to further feed back the adjustment of the target transmission 100.
More specifically, if the present invention relates to measurement of the clutch oil temperature to obtain a more comprehensive basic performance index of the targeted transmission 100 in order to complete the development of the transmission hydraulic-electric control, the transmission efficiency, the vibration noise quality, and the like, the measurement of the clutch oil temperature can be completed by supplying power to the input end of the clutch oil temperature sensor by using a precision voltage-stabilized power supply, connecting a voltage-dividing resistor in series, completing the measurement of the voltage at the end of the thermistor sensor for measuring the clutch oil temperature in the transmission by the analog acquisition module 23, and finally converting the voltage into the clutch oil temperature value corresponding to the measured voltage amount. In a preferred embodiment, the voltage dividing resistor is a precision resistor.
