Working method and principle:
As shown in Figure 3, gearshift intention sensor pull rod and gear-shifting inhaul cable Placement figure, connect together the steel wire of gear-shifting inhaul cable 208 with pull bar 301 of the present invention, can adopt the mode of welding or riveting.And shift handle 207 connects with gear-shifting inhaul cable 208.
As shown in Figure 4, gearshift intention sensor application of the present invention is in automatic clutch system, described automatic clutch system, for the automatic clutch system disclosed in Chinese patent 201410177392.9, this automatic clutch system mainly comprises ECU (Electrical Control Unit) 101, operating mechanism 103, stroke sensor 104, gear position sensor 108, composition such as parts such as gear shift intention sensor 109, clutch 106 etc.
As shown in Figure 5, the intention signal recorded when gear shift intention sensor tension or pressurized, represents in the mode of magnitude of voltage.During tension, voltage signal is V
1mV, during pressurized, voltage signal is V
2mV.
When driver has gearshift be intended to and stir shift handle 207, shift handle 207 can pull gear-shifting inhaul cable to move, thus drive gear shift intention sensor to produce gear shifting signal, shift signal passes to ECU (Electrical Control Unit) 101 by wire harness 102, ECU (Electrical Control Unit) 101 sends instruction rapidly after receiving signal, drives operating mechanism 103 to realize separation or the combination of clutch.
The working procedure of automatic clutch system of the present invention:
Driver clearly shifts gears intention, and stirs shift handle 207;
Generation and the application of gearshift intention signal are implemented according to Fig. 6 S401 ~ 406 step;
Gear shift intention authenticity judges S401, and the size of foundation gear shifting force judges that driver shifts gears intention authenticity.Can adopting and judge with the following method, when stirring shift handle 207, when gear-shifting inhaul cable pulling force or pressure are greater than 20N, just can cause the motion of slide block magnetic material 303, and then produce voltage signal.When pulling force is less than 20N, respective slide magnetic material 303 can not cause motion, and Hall transducer 307 also can not produce voltage signal.The object judged is the generation gear shifting signal that prevents driver's hand to be placed on shift handle 207 but the intention will do not shifted gears or vehicle jolt, and causes clutch mistake to be separated;
Produce S402 without effective shift signal, if do not have effective shift signal to produce, then do not produce voltage signal and pass to ECU (Electrical Control Unit);
Shift signal process confirms S403, processes the shift signal data gathered, and when drag-line tension, voltage output signal is V
1mV, during pressurized, voltage output signal is V
2mV, now confirms gearshift correct motive.If signal does not meet this two values, then can not produce voltage signal to ECU (Electrical Control Unit);
Shift signal receives S404, and gearshift intention signal is delivered to automatic clutch ECU (Electrical Control Unit) 101 by wire harness, realizes the acceptance of ECU (Electrical Control Unit) 101 to intention signal;
Operating mechanism action S405, ECU (Electrical Control Unit) 101 adopts and controls to export the dutycycle mode of PWM, realizes that direct current generator 201 starts, stability of rotation and speed regulating control with variable dutycycle, realizes operating mechanism 103 and moves;
Clutch separation or in conjunction with S406, ECU (Electrical Control Unit) 101 drives the motion of direct current generator 201, through speed reducer 202 transmission of pressure to master cylinder 203, because master cylinder 203 adopts oil pipe to be connected with clutch release slave cylinder 205, the pressure of master cylinder 203 is corresponding is delivered to clutch release slave cylinder 205, promote disengaging yoke 206 to move, and then disengaging yoke 206 promotes release bearing 204 and realizes clutch separation.So identify the gearshift intention of real driver, utilize operating mechanism 103 can realize rapidly clutch and be effectively separated.
