Its control route be: a road for by reservoir compartment through clutch electric pump to clutch accumulator to clutch conversion electromagnetic valve to clutch slave cylinder; Another road is to clutch conversion electromagnetic valve to clutch slave cylinder by reservoir compartment.Article two, oil circuit is by clutch conversion electromagnetic valve conversion and control.
(2) a kind of vehicle electric-controlled automatic clutch
A kind of vehicle electric-controlled automatic clutch is made up of hydraulic system and clutch electronic control system.
Vehicle electric-controlled automatic clutch hydraulic system
Vehicle electric-controlled automatic clutch hydraulic system is made up of a clutch control oil be made up of reservoir compartment, clutch master cylinder, automatically controlled throttle valve, clutch conversion electromagnetic valve, clutch slave cylinder and another clutch control oil be made up of reservoir compartment, clutch electric pump, clutch accumulator, clutch conversion electromagnetic valve, clutch slave cylinder etc.Article two, oil circuit is by clutch conversion electromagnetic valve conversion and control.This scheme can implement Non-follow control at any time when electric-controlled automatic clutch breaks down, and reduces the risk of vehicle driving.
Its control route be: a road for by reservoir compartment through clutch electric pump to clutch accumulator to clutch conversion electromagnetic valve to clutch slave cylinder; Another road is to clutch general pump to automatically controlled throttle valve to clutch conversion electromagnetic valve to clutch slave cylinder by reservoir compartment.Article two, oil circuit is by clutch conversion electromagnetic valve conversion and control.
Automatically controlled throttle valve.When automatically controlled throttle valve is not energized, during valve flow Kongzui large so that Non-follow control clutch, oil circuit is unimpeded; When driver completes gearshift, clutch conversion electromagnetic valve power-off return, by the oil circuit of clutch conversion electromagnetic valve normal open passage UNICOM clutch general pump to clutch slave cylinder; Automatically controlled throttle valve energising, metering orifice diminishes, and oil return is slack-off, and clutch smooth and steady is combined.The fluid avoiding clutch slave cylinder refluxes rapidly, causes clutch to combine rapidly suddenly the damage of the uncomfortable feeling of " rushing car " caused and the auto parts machinery caused thus.
Clutch electronic control system
Clutch conversion electromagnetic valve have one connect from automatically controlled throttle valve oil pipe liquid entering hole, one connect from the liquid entering hole of accumulator oil pipe and a liquid outlet to clutch slave cylinder.Vehicle electric-controlled automatic clutch has two kinds of mode of operations.One is MANUAL CONTROL mode; Another kind is automatic control mode.This system is provided with pattern handover trigger switch.Foot brake pedal, brake fluid by clutch master cylinder, through automatically controlled throttle valve, clutch conversion electromagnetic valve normal open passage to clutch slave cylinder, clutch separation; When clutch is in automatic control mode, clutch control unit sends instruction when receiving driver's gear shifting signal that gear shift sensing device transmits, clutch conversion electromagnetic valve is energized, cut off the oil circuit of clutch master cylinder to clutch slave cylinder, turn-on accumulator is to the oil circuit of clutch slave cylinder simultaneously, the separation of clutch.The clutch conversion electromagnetic valve power-off return when clutch control unit detects that gearshift puts in place, automatically controlled throttle valve energising simultaneously, metering orifice diminishes, the fluid of clutch slave cylinder gets back to clutch master cylinder through clutch conversion electromagnetic valve normal open passage, automatically controlled throttle valve, through the oil inlet hole of master cylinder to reservoir compartment.
Specific embodiments
Automobile electrically-controlled automatic clutch device is primarily of clutch master cylinder 1, clutch conversion electromagnetic valve 2, clutch electric pump 3, clutch accumulator 4, clutch slave cylinder 5, gear shift sensing device 6, clutch control unit 7, throttle valve control unit 8, throttle control actuating motor 9, engine rotation speed sensor 10, vehicle speed sensor 11, automatically controlled throttle valve 12, clutch operating mode diverter switch 13, input shaft speed probe 14, OSS 15 grade forms (as Fig. 1).
Clutch conversion electromagnetic valve 2 is arranged in the hydraulic pipe line of clutch master cylinder 1 and clutch slave cylinder 5.Be connected with the liquid entering hole e of clutch conversion electromagnetic valve 2 from the oil pipe of clutch general pump 1; Be connected with the liquid entering hole f of clutch conversion electromagnetic valve from the oil pipe of clutch accumulator 4; Be connected to the oil pipe of clutch slave cylinder 5 and the liquid outlet g of clutch conversion electromagnetic valve 2.
Gear shift sensing device 6, engine rotation speed sensor 10, vehicle speed sensor 11, input shaft speed probe 14, OSS 15 are connected with clutch control unit 7 separately; Clutch conversion electromagnetic valve 2, automatically controlled throttle valve 12, throttle valve control unit 8 are connected with clutch control unit 7 separately; Closure actuating motor 9 is connected with throttle valve control unit 8.
Driver shifts gears let slip the clutch, the fluid of clutch general pump through automatically controlled throttle valve 12 to the e-b-a-g passage of clutch conversion electromagnetic valve 2 to clutch slave cylinder 5, clutch separation.Unclamp pedal, the fluid of clutch slave cylinder 5 turns back to clutch general pump by former path and finally gets back to reservoir compartment.
When clutch is in automatic control mode, clutch control unit 7 sends instruction to clutch conversion electromagnetic valve when receiving driver's gear shifting signal that gear shift sensing device 6 transmits, clutch conversion electromagnetic valve 2 is energized action, cut off the path of clutch master cylinder 1 to clutch slave cylinder 5, connect the path of clutch accumulator 4 to clutch slave cylinder 5 simultaneously.The brake fluid of accumulator through the f-d-c-g passage of clutch conversion electromagnetic valve to clutch slave cylinder 5, clutch separation.Send instruction when clutch control unit detects that gearshift puts in place to clutch conversion electromagnetic valve, clutch conversion electromagnetic valve power-off return, connect the f-b-a-g passage of clutch master cylinder to clutch slave cylinder.Clutch control unit sends instruction to automatically controlled throttle valve 12 simultaneously, and automatically controlled throttle flow rate hole diminishes, and the brake fluid of clutch slave cylinder gets back to reservoir compartment by automatically controlled throttle valve throttling through clutch master cylinder.
When clutch control unit receives gear shifting signal, the operating condition of the signal adjustment motor transmitted according to engine rotation speed sensor, vehicle speed sensor, input shaft speed probe, OSS etc. makes clutch conversion electromagnetic valve solenoidoperated cluthes under optimized state.Make smooth gear shifting, clutch combines steadily, fuel-economizing, reduces parts damage, extends vehicle service life.
