The device shown in Fig. 1, operates as follows. During the rotation of the crankshaft of the engine at the output of the sensor 1 of the angular velocity of the motor shaft is formed of a pulse sequence with a repetition frequency proportional to the angular velocitytothe motor shaft. These pulses arrive at the input device 32 compare, where they are compared with the pulses generated by the sensor 31 speed, the frequency of which is proportional to the speed of transport is analog Converter 2, where they are converted into a DC voltage, which controls the operation of the controller 3 current, resulting in a change in the current flowing in the control winding 14, and hence americki (IW) of the electromagnet witness the action from the value IWxxcorresponding to the total value of the angular speed of the idling shaft of the engine and vehicle speedXXto the value of IWnlcorresponding to the value ofnlthreshold clutch lock. Thus there is a smooth approximation of the friction elements of the clutch, allowing the starting of the vehicle. Since the start of the vehicle from the sensor 31 speed begins to produce pulses with a repetition frequency, increasing with increasing speed. The summation of the pulses from the sensor 1 of the angular velocity of the motor shaft and the sensor 31 of the speed of the vehicle covered by the positive feedback that gives at the beginning of smooth and then all over a sudden increase in the slope of the convergence of the friction elements of the clutch. The process becomes avalanche-like character. Upon reaching the vehicle speed Vathe value of Vnlthe voltage level on wychowania witness steps to zero, this provides a complete clutch friction elements of the clutch, i.e., lock. Unlock the clutch occurs when the reduction of the voltage level at the output of frequency-to-analog Converter 2 to the value corresponding to VRBequal to the value of Vnlthat becomes possible due to the fact that this level voltage corresponds to the lower limit of stable operation of the engine when driving. Which is impossible when you lock the clutch on the engine speed. This process proceeds as follows. The signal output from the controller 3 a current is supplied to the third input device 35 18 run control generator 17 single pulses, at the output of the generator 17 single pulses is formed of a single pulse, which affects the key amplifier 16 current through the first diode 19 to the controller 3 current so that the control winding 14 and afterburning winding 15 of the electromagnet witness steps americki increase to maximum values of IWRBthat provides quick off the clutch. At the end of a single pulse value Ampervilla electromagnet witness the action is reduced to a value of IWbeats, which provides a reliable uderzenie the status of the binary sensor 23 of the original pedal position throttle of the carburetor. This process proceeds as follows.

When the pedal is released, the throttle of the carburetor low level voltage is supplied from einverseremove output binary sensor 23 of the original pedal position throttle control to the second input 34 input frequency-analog Converter 2, which leads to a decrease in the magnitude of its output voltage to compensate for the possible increase in voltage with increasing angular velocity of the motor shaft due to incorrect adjustment of the carburetor. After pressing the foot pedal the throttle valve of the carburetor to the second input 34 of the frequency-to-analog Converter 2 is energized, allowing its operation in a particular mode. In normal driving americki electromagnet witness steps are reduced to values IWnstart soft-start clutch. Next, the value of IWnsaved by increasing the current total value of the angular velocity of the motor shaft and the speed of the vehicle. Upon reachingtoVavalues nfurther change Ampervilla occurs depending on the angular velocity of the motor shaft, a speed TRANS is t to be shifting, the alarm push the clutch switch 12 push clutch, located on the shift lever, acting on the second input device 30 18 run control generator 17 single pulse trigger generator 17 single pulses, the output of which is formed of a single pulse, a description of the impact which the nodes are shown above. The result is increased Ampervilla electromagnet witness steps IWRB. The system adjusts to the mode-locking clutch according to the signal V'nlwith speed sensor. In that case, if after the shift speed of the vehicle Vais greater than the value V'nl, americki electromagnet witness steps are reduced to zero. If vehicle speed is less than value V'nlthen americki electromagnet witness steps will change depending on changes toVaby law, described above.

The operation of the device in the event of a shift in the mode of the steady movement of a vehicle similar to the one described.

Upravleniekrovlia fully the clutch in the range RB<tovand<nl(such as braking or the time limit of the acceleration rate to a lower gear), proceeds as follows. The potential of the low level binary sensor 23 of the original pedal position throttle of the carburetor through the inverting output is fed to the first input device 29 18 run control generator 17 single pulses and triggers the output of the generator 17 single pulse single pulse, the caller, as described earlier, an increase of Ampervilla electromagnet witness the action up to a maximum value IWRBproviding cycle Orazbakov not completely blocked adhesion in the rangeRB<tovand< nl.

This prevents possible engine shutdown and, if necessary, maintained stock of inertia of the vehicle in the acceleration phase. The operation of the clutch when Troubleshooting electronic and electrical parts of the device is performed in classic mode using the clutch pedal, connected via cable drive with a fork clutch.

The device shown in Fig. 3, operates as follows. When the rotation is with the selected repetition rate, proportional to the angular velocitytothe motor shaft. These pulses are received at the first input 33 of the frequency-to-analog Converter 2, where they are converted into the DC voltage and fed to the second input device 65 54 summation. On the first input device 64 54 summation supplied voltage with additional frequency-analog Converter 53, connected to the output of the sensor 31, the vehicle speed proportional to the speed of the vehicle. The signal from the device 54 summation controls the operation of the controller 3 current, resulting in a change in the current flowing in the control winding 14, and hence americki (IW) of the electromagnet witness the action from the value IWxx(see Fig. 4) corresponding to the sum of the values of angular velocity idling shaft of the engine and vehicle speedxxto the value of IWnlcorresponding to the sum of the values of angular velocity of the shaft of the engine and vehicle speed nlthreshold clutch lock. Thus there is a smooth approximation of the friction elements of the clutch, allowing the starting of the vehicle. Upon reaching the speed of transport crestway to the second input 21 of the knob 3, the current through the switching device 55 and causes the reduction of Ampervilla electromagnet witness steps to zero, this provides a complete clutch friction elements of the clutch, i.e., lock. When this occurs, the reset relay 50 lock control clutch so that it returns to its original state can occur only when the speed reduction of the vehicle up to the value of VRB.

Decreasing the vehicle speed Vato the value of VRBcorresponding to the threshold unlock the clutch on the output relay 50 lock control clutch, coming in at third input device 35 18 run control generator 17 single pulses, at the output of the generator 17 single pulses is formed of a single pulse, which affects the key amplifier 16 current through the first diode 19 to the controller 3 current so that the control winding 14 and afterburning winding 15 of the electromagnet witness steps americki increase to maximum values of IWRBthat provides quick off the clutch.

At the end of a single pulse value Ampervilla electromagnet witness the action is reduced to a value of IWbeats, which provides a reliable hold clutch off is similar pedal position throttle of the carburetor. This process proceeds as follows.

When the pedal is released, the throttle of the carburetor low level voltage is supplied from einverseremove output binary sensor 23 of the original pedal position throttle control to the second input 34 input frequency-analog Converter 2, which leads to a decrease in the magnitude of its output voltage to compensate for the possible increase in voltage with increasing angular velocity of the motor shaft due to incorrect adjustment of the carburetor. After pressing the foot pedal the throttle valve of the carburetor to the second input 34 of the frequency-to-analog Converter 2 is energized, allowing its operation in a particular mode. In normal driving americki electromagnet witness steps are reduced to values IWnthe beginning of the soft start clutch, Then the value of IWnsaved by increasing the current value of toVa. Upon reachingtoVavaluesnfurther change Ampervilla occurs depending on the total value of the angular velocity of the motor shaft and the speed of the vehicle and is not different from the experience signal push clutch switch 12 push clutch, located on the shift lever, acting on the second input device 30 18 run control generator 17 single pulse trigger generator 17 single pulses. At the output of the generator 17 single pulse is formed by a single pulse, a description of the impact which the nodes are shown above. The result is increased Ampervilla electromagnet witness steps to IWRB. While the input unit 51 reconfigure the relay 50 lock control clutch is formed by a low-level signal which relay 50 control locking clutch adjusts to the mode lock on a signal from the sensor 31 speed V'nlin the range VRB<V' nl<V nl. In that case, if the speed of the vehicle is greater than the value V'nloccurs the relay 50 lock control clutch and americki electromagnet witness steps are reduced to zero. If vehicle speed is less than the value V'nlthen americki (IW) of the electromagnet witness actions change depending on changestoVaby law, described above. Upon reaching the speed of transport is gnite witness steps are reduced to zero, i.e., the clutch is locked.

The operation of the device in the event of a shift in the mode of the steady movement of a vehicle similar to the one described.

The operation of the clutch in situations associated with discharge pedal throttle of the carburetor when fully unlocked clutch in the rangeRB<tovand<nl(such as braking or the time limit of the acceleration rate to a lower gear) proceeds as follows.

The potential of the low level binary sensor 23 of the original pedal position throttle of the carburetor through the inverting output and the element 32 "And" (with a potential high level output relay 50 lock control clutch) is supplied to the first input device 29 18 run control generator 17 single pulses and triggers the output of the generator 17 single pulse single pulse, the caller, as described earlier, an increase of turns of the electromagnet witness the action up to a maximum value IWRBproviding cycle Orazbakov nerazpakovanno fully clutch in the rangeRB<tovand< is ircII vehicle in the phase of acceleration.

The operation of the clutch when Troubleshooting electrical and electronic systems the device is running in classic mode using the clutch pedal connected via troscopy drive with a fork clutch (not shown).

The device shown in Fig. 5, operates as follows. During the rotation of the crankshaft of the engine at the output of the sensor 1 of the angular velocity of the motor shaft is formed of a pulse sequence with a repetition frequency proportional to the angular wKthe speed of the motor shaft. These pulses are fed to the input circuit 66 comparison, where they are compared with the pulses generated by the sensor 31 speed, the frequency of which is proportional to the speed of the vehicle. The pulse sequence with the output of the circuit 66 of the comparison is fed to the input of the frequency-to-analog Converter 2, where it is converted into a DC voltage, which controls the operation of the controller 3 current, resulting in a change in the current flowing in the control winding 14, and hence americki (IW) of the electromagnet witness the action from the value IWxx(see Fig.6), corresponding to angular velocity of idling of the motor shaftto, to the value IWb is the approximation of the friction elements of the clutch, providing a moving vehicle. Upon reaching the vehicle speed Vathe values of Vnlmatching to within 10% with the current value of the angular velocitytomotor shaft, the output frequency analogue Converter 2 sets the voltage the magnitude of which is sufficient for operation of the relay 50 lock control clutch, the output of which acts on the first input 20 of the knob 3, the current through the switching device 55 and causes the reduction of Ampervilla electromagnet witness steps to zero, which ensures complete clutch friction elements of the clutch, i.e., lock. When this occurs, the reset relay 50 lock control clutch so that it returns to its original state can occur only when the decrease in the vehicle speed Vato the value of VRB. Reducing a speed of the vehicle up to the value of VRBcorresponding to the threshold unlock the clutch on the output relay 50 lock control clutch, coming in at third input device 35 18 run control generator 17 single pulses, at the output of generators the first diode 19 to the controller 3 current thus in the control winding 14 and afterburning winding 15 of the electromagnet witness steps americki increase to maximum values of IWRBthat provides quick off the clutch. At the end of a single pulse value Ampervilla electromagnet witness the action is reduced to a value of IWbeats, which provides reliable retention of the clutch switch is turned off.

When the pedal is released, the throttle of the carburetor low level voltage is supplied from einverseremove output binary sensor 23 of the original pedal position throttle control to the second input 34 input frequency-analog Converter 2, which leads to a decrease in the magnitude of its output voltage to compensate for the possible increase in voltage with increasing angular velocity of the motor shaft due to incorrect adjustment of the carburettor.

Start current soft-start is generated based on the status of the binary sensor 23 of the original pedal position throttle of the carburetor. After pressing the foot pedal the throttle valve of the carburetor to the second input 34 of the frequency-analog Preobrazovatel the key electromagnet witness steps are reduced to values IWnstart soft-start clutch. Next, the value of IWnsaved by increasing the current value of the angular velocity of the motor shaft. Upon reaching the angular velocity of the motor shaft valuenfurther change Ampervilla occurs depending on the angular velocity of the motor shaft, the speed of the vehicle and does not differ from those described above.

If in the process of acceleration of the motor shaft will be shifting, the signal push clutch switch 12 push clutch, located on the shift lever, acting on the second input device 30 18 run control generator 17 single pulse trigger generator 17 single pulses, the output of which is formed of a single pulse, a description of the impact which the nodes are shown above. The result is increased Ampervilla electromagnet witness steps to IWRB. While the input unit 51 reconfigure the relay 50 lock control clutch is formed by a low-level signal, which relay 50 control locking clutch adjusts to the transition in regiolls values V'nloccurs the relay 50 lock control clutch and americki electromagnet witness steps are reduced to zero. If vehicle speed is less than the value V'nlthen americki (IW) of the electromagnet witness actions change according to the law described above, depending on the angular velocity of the motor shaft. Upon reaching the vehicle speed value V'nlis the relay 50 lock control clutch and americki electromagnet witness steps are reduced to zero, i.e., the clutch is locked.

The operation of the device in the event of a shift in the mode of the steady movement of a vehicle similar to the one described.

The operation of the clutch in situations associated with discharge pedal throttle of the carburetor when the angular velocity of the motor shaft RB<to<nl(for example, for inhibiting or temporary limitation of the acceleration rate to a lower gear), proceeds as follows.

The potential of the low level binary sensor 23 of the original pedal position throttle of the carburetor through investing in is supplied to the first input device 29 18 run control generator 17 single pulses and triggers the output of the generator 17 single pulse single pulse, the caller, as described earlier, an increase of Ampervilla electromagnet witness the action up to a maximum value IWRBproviding cycle Orazbakov not completely blocked adhesion in the rangeRB<to<nlThis prevents possible engine shutdown and, if necessary, maintained stock of inertia of the vehicle in the phase of acceleration.

The operation of the clutch when Troubleshooting electronic and electrical parts of the device is performed in classic mode using the clutch pedal connected via troscopy drive with a fork clutch (not shown).
