Below with regard to operating modes such as vehicle driving, parking Parking, car ramp Parking and start assistings, explain.
When vehicle was normally driven a vehicle, mechanism position was as shown in Figure 6, and this moment, mechanism did not retrain fluted disc.
Vehicle parking Parking operating mode:
When vehicle stopped Parking, chaufeur was opened the Parking switch, and control system controlling and driving motor 12 drives retarder 11 and makes trip 5 left-hand revolution certain angles.Drive pin 8 arrives and horizon level position.This moment, trip 5 had two kinds of situation:
First kind, get at the bottom of the tooth of Parking gear 2, realize Parking, as shown in Figure 5.
Second kind, trip 5 by the tooth top of Parking gear 2 block do not get into tooth at the bottom of.This moment, trip 5 was withstood by tooth top, trip 5 line of centerss turn to horizon at angle, departed from balance position, 9 pairs of trips 5 of U-shaped retracing spring have a downward reseat pressure.If the road surface is uneven slightly, after wheel drove Parking gear 2 slight rotations, trip 5 can fall at the bottom of the tooth, blocks Parking gear 2 and makes it and can't rotate again, accomplishes Parking, and was as shown in Figure 5.
Car ramp Parking and start assisting operating mode:
Vehicle is after coming to a complete stop in the ramp, and chaufeur is pressed the Parking button after slamming brake.Control system at first detects inclination angle, the residing ramp of present vehicle according to obliquity sensor.According to practice test, the gradient is spent in 5 degree scopes 3, and the vehicle tendency toward sliding is slow, and chaufeur does not need ancillary system that enough reaction time startings are also arranged, and this moment, system can not work.If angle is greater than setting threshold value, ramp start assisting function can be opened by system.
At first carry out parking function when stop in the ramp, after the Parking instruction was finished the chaufeur releasing of brake, the vehicle by gravity was retreated, Parking gear 2 clickwises when supposing to retreat.Can withstand like trip that preceding text are sayed 5 that Parking gear 2 makes it can't be again along clickwise, and vehicle stops to retreat, and accomplishes the ramp Parking.
When step recurrence, controller detects Das Gaspedal when stepping on certain depth and gear and being in non-reverse, judges that begin to start to walk for vehicle this moment.Controller control motor 12 drives retarder 11 and drives the trip 3-10 of mechanism clickwise one angle.This moment, drive pin 8 was still in the action radius of the waist type spacing hole of trip 5, drive pin 8 and trip 5 no relativity power.Because vehicle is in the ramp, have a sliding force, by tire be passed to that the flank of tooth that makes Parking gear 2 and trip 5 press mutually and the friction force that produces greater than the reseting elasticity of U-shaped retracing spring 9, cause trip 5 to rotate with driver train.The U-shaped retracing spring departs from balance position 9 this moments, and a reset force that promotes trip 5 clickwises is arranged.When the vehicle accelerator pedal is stepped on down; Vehicle drive force increases to when enough overcoming gradient resistance gradually; Parking gear 2 has the trend of left-hand revolution; Pressure between trip 5 and the Parking gear 2 reduces to cause each other gradually, and friction force reduces, final under the reset force effect of retracing spring 9 trip 5 throw off Parking gears 2 and forward balance position fast to and no longer restrict Parking gear 2.Vehicle is promptly accomplished uphill starting.In like manner, the vehicle starting of on the downhill path, moveing backward also can realize the start assisting function.
Vehicle is along the direction of fall Parking operating mode that glides again:
In the actual life, automobile is along the direction of fall Parking, and vehicle just can be started to walk to lower slider during startup, and this also is very general operating mode.When vehicle after the ramp Parking finishes, if chaufeur hopes that descending slides.If system detects chaufeur and has slammed brake; Control system control motor 12 make trip 5 under driver train drives one of clickwise than wide-angle; Turntable 10 drives drive pin 8 rotations until the waist type spacing hole upper end of withstanding trip 5; This moment, drive pin 8 can transmit driving torque to trip 5, forced to drive trip 5 rotations.Although also there is friction force in the flank of tooth of trip 5 and Parking gear 2, drive torque can be greater than friction torque after the deceleration torque dupler amplifies for drive motor 12, and trip 5 just can be thrown off Parking gear 2.This moment, vehicle did not receive system restriction, and releasing of brake can be driven a vehicle.In like manner, vehicle is along the Parking of upward slope direction, and the function of retreating slip along direction of fall also can realize.
