Description

The automobile machinery automatic control device of clutch
Affiliated technical field
The present invention relates to a kind of automobile machinery automatic control device of clutch, be particularly useful for installing on traditional armstrong's patent formula power-transfer clutch, realize the clutch control function of automatic clutch for car.
Background technology
What at present, the car Automatic Transmission was generally used is the hydraulic type automatic transmission structure [1]The structure of hydraulic type automatic transmission with hydraulic torque converter is compared with hand-operated transmission, is very different in structure and use.Hand-operated transmission mainly is made up of gear and axle, produces the speed change bending moment by different gear combination; And the hydraulic type automatic transmission with hydraulic torque converter is made up of turbine transformer, planetary wheel and hydraulic control system, and the mode by fluid power transmission and gear combination reaches the speed change bending moment.
Hydraulic type automatic transmission with hydraulic torque converter clutchless gear shift, gear change greatly less, connect steadily, so processing ease, both brought convenience to the driver, also giving by bus, the people brings comfortable.But the hydraulic type automatic transmission with hydraulic torque converter that adopts exists complex structure, part processing precision to require height, big, the more high shortcoming of cost of manufacture difficulty now, has limited the application of this system on low-grade vehicle [2,3]

Fig. 2 is the position form of adding shifting switch and slope starting switch on the gear change hand lever, and Fig. 3 is the circuit erection joint of controlling computer, and Fig. 4 is the car load line connecting method of control setup.
Shown in Figure 5 is the structural representation of actr, and the manipulation of automobile machinery power-transfer clutch is to rely on DC machine to drive, and therefore, the effect of the actr of automatic control device is that rotatablely moving of motor is converted into the required straight-line motion of clutch control.In addition, in the engaging process of actr control clutch, the subsidiary measuring ability that actuator position is arranged.The main body of actr is a permanent magnet direct current motor that has damping spring, and damping spring is attached to the motor outside, has speed reduction gearing in the motor.The effect of the transmission device of actr is that rotatablely moving of motor is converted into straight-line motion.
The output shaft of motor drives crank and rotates, and the bearing pin A of the crank other end is paddling in the paddle-tumble A of trace, and making trace is that rotate at the center with the center shaft of support, drives the bearing pin B pulling pull bar of trace opposite side.Clutch cable and bearing pin C link together, and bearing pin C when pull bar moves, drives bearing pin C and clutch cable and moves together in the paddle-tumble B of pull bar.Clutch cable is connected with clutch slipper yoke, and the control clutch sense of motion is realized the action that suits of power-transfer clutch.When not using automatic control device of clutch, clutch cable and bearing pin C can free motions in paddle-tumble B, do not influence the original steering unit operated clutch of power-transfer clutch.
Interposition at trace is equipped with the stroke moving contact, and it is by spring application steel ball paddling on the actuator position check-out console.Check-out console is a circuit card that has scale, and its effect is the movement position that detects actr, and it and paddling contact are formed a linear selection switch jointly.
Paddling contact shown in Figure 6 self ground connection, trace motion drive the contact and contact with corresponding wiring scale, and then this position connects low level, inputs to the position signal of microcontroller as actr by lead-in wire.The actuator position signal divides 5 state of a controls, and when actr trace drive paddling contact moves to the S1 position (position shown in Figure 5), the S1 zone is by paddling contact ground connection on the check-out console, and this moment, control system obtained the information of power-transfer clutch full engagement.Actr tells control system to work as the mode of operation of front clutch in this way.The controller characteristic curve of 5 position signals is as shown in table 2.
Table 2 clutch position information definition
Mark Describe Choice of location is set
S1 Disengaging of clutch Power-transfer clutch separates fully.
S2 Contact is slided The sliding position of selecting power-transfer clutch to begin to contact.
S3 Break-in drags Select power-transfer clutch just rubbing and drag the position of vehicle, vehicle body begins that mobile phenomenon is arranged.
S4 The afterburning drive Select automobile fuel filler promptly to drive the position of walking.
S5 Clutch engagement The power-transfer clutch full engagement.
In clutch drive apparatus, the clutch position touch block is housed, as the control foundation of travel of clutch.Because the travel of clutch of different automobiles is installed length difference is arranged slightly, and driver's manipulation impression is different, so three position S2 in the middle of on the clutch position check-out console, S3, S4 is adjustable, set its optimum position by three group selection switches on it, to adapt to the effect of various clutch control strokes.The definition and the basis of design of each position are as shown in table 2.
In Fig. 7, FUSE is that the power supply of controlling computer always insures, capacity 10A.SWITCH is the battery isolator control of controlling computer, and the time spent is not closed this switch for a long time.K.C. the car speed sensor kind is set, MS3 → 4 and MS2 → 3rd, and actuating device joint rate parameter configuration switch, EBS are automobile brake critical speed value configuration switchs, M.B. is that the sensor voltage parameter is selected configuration switch.
Principle is put in stepping on soon of pedal of clutch slowly, it is the basic operation skill that mechanical clutch is handled, suitably the control intermediary is let slip journey slowly, takes into account the requirement of vehicle smooth-ride simultaneously, and clutch automatic control system is divided into S1 with the control travel of power-transfer clutch, S2 → S3 → S4, five sections of S5, by controlling computer according to incoming signal, the inter-zone trip digit rate, and the position of section, the execution action of accessory drive actuating motor.
MS3 among Fig. 7 → 4 and MS2 → 3 are two groups of actuating device joint rate parameter configuration switchs, need be according to driver individual's manipulation fancy setting.Every group is made of 4 switches, binary numeral " 1 " is represented in each switch " ON " position, and binary numeral " 0 " is represented in " OFF " position, and 4 switches are formed from " 0 " to " 15 " clutch engagement control digit rate of totally 16 grades, " 0 " is the slowest, and " 15 " are the fastest.
