Next, the structure of the variable resistor 5 will be described.

If a deflection occurs in another direction, the resistance becomes large. In Figs. 5A and 5B, on the upper half arc 51 and the lower half arc 52, the portion where the hatching is drawn indicates the resistance of the access circuit, and the hatching on the outer frame shaft 21 shows only the section, and is independent of the resistance. .

Referring to Fig. 8, a state diagram of the use of the gyroscope assembly is shown, which is connected to the mounting surface by the mount 14.

The invention discloses a cab stability system, comprising: five main components: a gyroscope 1, a controller S2, a regulator S3, an air reservoir S4 and a solenoid valve S5. The function of the gyroscope 1 is to acquire a signal of a vehicle attitude. The gyroscope 1 can use two single-degree-of-freedom gyroscopes 1 or a multi-degree-of-freedom gyroscope 1. These applications are not limited, and can be used in the present application as long as the posture information of the vehicle can be acquired. The gyroscope 1 is also in communication with the controller S2, mainly electrically connected, so as to be able to transmit the attitude information of the vehicle to the controller S2 as a point signal, so that the controller S2 can acquire the attitude signal of the vehicle, and further, the controller S2 will The adjuster S3 is controlled to adjust the posture of the vehicle based on the attitude signal.

The structure of the adjuster S3 will be explained below, and how the action is controlled by the controller S2.

The adjuster S3 has an air bag S6, and the pressing head S7 is formed at both ends of the air bag S6. After the air bag S6 is inflated, the two end pressing heads S7 are elongated, and the pressing heads S7 at both ends after the exhausting are shortened. The inflation of the air bag S6 is realized by the air reservoir S4 and the electromagnetic valve S5, and the electromagnetic valve S5 can have three interfaces, respectively, an air inlet, a gas supply port and an air outlet (hereinafter may be referred to as three interfaces), the air inlet The air reservoir S4 is connected, the air supply port is connected to the air bag S6, and the air supply port and the air inlet are connected to realize communication between the air reservoir S4 and the air bag S6, and inflated to the air bag S6. The exhaust port communicates with the outside, and when the exhaust port and the air supply port are in communication, the air in the air bag S6 can be discharged from the exhaust port. Of course, when the airbag S6 is stable, for example, no adjustment is required, or adjustment is completed, and the posture is maintained, the three interfaces are not in communication with each other.

Of course, in order to achieve the charging and discharging of the airbag S6 by the air reservoir S4, in addition to the solenoid valve S5, a gas pipe connected between the components is required. A check valve S9 is also disposed outside the air reservoir S4 to restrict the airflow direction.

The controller S2 not only connects the gyro 1 but acquires the attitude signal, and the controller S2 also communicates with the electromagnetic valve S5 to control the communication relationship between the air inlet, the air supply port and the air outlet. Of course, the specific control mode needs to be adjusted according to the position set by the adjuster S3, mainly when the vehicle is tilted, and the airbag S6 of the adjuster S3 corresponding to the corresponding position is charged and deflated to adjust the posture of the cab.

Further, the regulator S3 is provided with a pressure sensor, and the controller S2 is connected to the pressure sensor to acquire pressure data in the airbag S6. The controller 3 can acquire the pressure data in the airbag S6, so that when the controller S2 controls the solenoid valve S5, it can combine the attitude signal acquired from the gyro 1 and the pressure signal acquired from the airbag S6 (it can also be said to be The air pressure signal), through the mutual feedback of the two signals, the controller S2 realizes posture adjustment of the vehicle, especially the vehicle cab.

Through the above, it can be known that the controller S2 is respectively transmitted by the signal between the airbag S6, the gyroscope 1, and the electromagnetic valve S5. Referring to FIG. 9, in order to show a connection relationship, each connection line is shown in a different line type, and the controller S2 and solenoid valve S5 are connected by a solenoid valve control line, controller S2 and airbag S6 are connected by a balloon pressure signal line, and controller S2 and gyroscope 1 are connected by a gyroscope angle signal line.

In order to further increase the stability of the adjustment, the adjuster S3 and the solenoid valve S5 respectively have four. For convenience of explanation, one adjuster S3 and one solenoid valve S5 are used as one adjustment group, and there are four adjustment groups in total, between the groups. Parallel settings.

In the adjustment group, the intake ports of each of the solenoid valves S5 are respectively communicated with the air reservoir S4, and the controller S2 is connected to communicate with each of the solenoid valves S5. The control of each solenoid valve S5 by the controller S2 is performed independently. Similarly, the acquisition of the pressure signal of each airbag S6 is also independent, so it can be understood that each adjuster S3 is provided with a pressure sensor, and the controller 3 is connected with each pressure sensor to obtain each airbag. Pressure data in S6.

For convenience of description, the adjuster S3 is divided into a first adjuster S31, a second adjuster S32, a third adjuster S33, and a fourth adjuster S34. Correspondingly, the airbags S6 in each group are also divided into first airbags. S61, a second airbag S62, a third airbag S63, and a fourth airbag S64. Correspondingly, the solenoid valve S5 is also divided into a first solenoid valve S51, a second solenoid valve S52, a third solenoid valve S53, and a fourth solenoid valve S54.

The four adjusters are all set at the bottom of the cab S8, respectively on the front left side of the front, the front right side of the front, the left rear side of the front and the right rear side of the front.

This type of setting allows for front, back, left and right tilt adjustments.

A sensitivity adjustment system S10 is provided on the controller S2. It can be set by four gears, and the sensitivity of each gear is different. For example, when the sensitivity of the gyroscope 1 is 3° when the vehicle attitude is high, it is judged that the tilting needs to be adjusted, and when the sensitivity is low, the vehicle attitude is low. When the inclination is 10°, it will be judged that adjustment is needed. Of course, the sensitivity adjustment system S10 can be integrated in the controller S2 or can be connected to other positions, and it is connected to the controller S2 through the sensitivity adjustment signal line.

The function of the sensitivity adjustment system S10 can be realized by controlling the resistance of the access resistance. For example, the total resistance is divided into four gears, and the sensitivity from the first gear to the fourth gear is gradually increased. Correspondingly, the resistance values of the access circuits corresponding to each gear are different, which may be The greater the resistance value, the higher the sensitivity. These are the control realized by the electrical signal, and the description will not be repeated.

Generally, when the switch is gradually increased from the fourth gear of the first gear, the controller S2 selects and judges the electric signals (attitude signal and pressure signal) of the gyroscope 1 and the airbag S6, and performs an adjustment action, for example (the gears are in Roman numerals) Mark), when the I gear, the output angle of the gyroscope 1 reaches 10°, the controller S2 adjusts. When the gear is in the II gear, the gyroscope output angle is 7°, the adjustment is made. When the III gear is in the III gear, the gyroscope 1 outputs the corner. At 5°, the adjustment is made. When the gyro 1 is output only 3° in the IV position, the adjustment is immediately performed, that is, the control of the swing angle range of the cab S8 is getting smaller and smaller, thereby achieving the effect of gradually increasing the sensitivity.

When the vehicle is in very good road conditions, such as a very smooth highway road surface, the cab S8 swings very small, and the adjustment sensitivity can be selected in the high-end position; when the vehicle is in poor road conditions, such as stone pavement, the cab The S8 is always in the wide-angle swing range, and the adjustment sensitivity can be selected in the low gear to enhance the driver's perception of the road conditions.

Referring to FIG. 11 and FIG. 12, the state in which the gyroscope 1 senses the attitude of the cab S8 is shown. For example, the gyroscope 1 senses the right and left inclination angle of the cab S8, the right tilt angle is represented by ω-, and the left tilt angle is represented by ω+, that is, the left and right direction. The angle between the center line of the cab S8 and the vertical line changes. The above left and right tilts are based on the perspective of the driver sitting in the cab. 13 and 14, the gyroscope 1 senses the forward and backward inclination angle of the cab S8, the forward tilt angle is represented by θ+, and the backward tilt angle is represented by θ-, that is, the angle between the center line of the cab S8 and the vertical line in the front-rear direction changes.

In combination with the above four tilting conditions, it is set that the voltage signal output by the gyroscope 1 when the left tilt is the positive voltage signal U _ω+ ; the voltage signal output by the gyroscope 1 when the right tilt is the negative voltage signal U _ω- ; the gyroscope 2 when tilting forward The output voltage signal is a positive voltage signal U _θ+ ; the voltage signal output by the gyro 2 during backward tilting is a negative voltage signal U _θ- .

At the three interfaces that engage the solenoid valve S5, the control time of the controller S2 to the solenoid valve S5 is millisecond, that is, the control operation of the state of the cab S8 can be completed in a very short time, and the time interval between the two operations Also in milliseconds.

The pressure sensor provided on the regulator S3 acquires the pressure value in the airbag S6, and sends a pressure signal to the controller S2. When the airbag S6 is in the equilibrium state, the pressure signal may not be output to the controller (of course, it may be in the corresponding equilibrium state). The signal content, which is not limited), also has no charge and discharge action; when the air bag S6 is in the compressed state, the positive voltage signal U _P+ is output to the controller S2, and the controller S2 will according to the pressure signals of the four air bags S6 and two After the angle signal of the gyroscope is judged by the working condition, the airbag S6 is determined to be charged and deflated;

When the airbag S6 is in the extended state, the negative voltage signal U _{P- is} output to the controller S2, and the controller will judge the working condition according to the pressure signals of the four airbags S6 and the angle signals of the two gyroscopes, and then decide to The air bag is charged and deflated.

The positive voltage signal U _P+ and the negative voltage signal U _P- are respectively distinguished by four numbers 1-4 for different air bags. For example, the positive voltage signal output by the first air bag S61 is written as U _P1+ , and the second air bag S62 is output. The negative voltage signal is written as U _P2- .

In combination with the above voltage signal, when the vehicle is traveling on an uphill road surface, the cab S8 is inclined backward with respect to the horizontal plane, the gyroscope output U _θ- angle signal detecting the forward and backward inclination angle of the cab S8, and the first airbag S61 and the second rear behind the cab S8 The airbag S62 detects the U _P1- and U _P2- pressure reduction signals, and the third airbag S63 and the fourth airbag S64 detect the U _P3+ and U _P4+ pressure increase signals. After the correlation signal is input to the controller S2, the controller S2 controls the first. The solenoid valve S51 and the second solenoid valve S52 perform exhausting of the first airbag S61 and the second airbag S62, and the third electromagnetic valve S53 and the fourth electromagnetic valve S54 inflate the third airbag S63 and the fourth airbag S64, Thereby, the cab S8 is adjusted to return to the horizontal state.

When the vehicle is traveling on a high-altitude slope, the cab S8 may be tilted left or right relative to the horizontal plane. Here, the left tilt is set, and the gyroscope 1 detecting the forward and backward tilt angle of the cab S8 outputs a U _{ω +} angle signal, while the first airbag S61 and the third airbag S63 detect the U _P1+ and U _P3+ pressure increase signals, and the second airbag S62 and the The four airbags S64 detect the U _P2- and U _P4- pressure reduction signals, and after the relevant signals are input to the controller S2, the controller S2 controls the first electromagnetic valve S51 and the third electromagnetic valve S53 to the first airbag S61 and the third airbag. S63 performs inflation, and the second solenoid valve S52 and the fourth solenoid valve S54 perform an exhaust operation on the second airbag S62 and the fourth airbag S64, thereby adjusting the vehicle body return level state.

Since there are many working conditions when the vehicle is running, it will not be enumerated one by one.
