In rural roads, the road surface is uneven, and in the process of driving agricultural vehicles, agricultural machinery drivers will inevitably encounter some special emergencies such as tire burst, brake failure, and loss of steering control. If these sudden failures cannot be dealt with in a timely and correct manner, it is easy to cause a vicious accident in which vehicles are destroyed. It is necessary for the farmer to understand the solution to some sudden failures. The tire suddenly burst during driving Before the tire bursts, if the vehicle is running, it is generally not easy to find. The driver only discovers when the vehicle emits a popping sound and there is a tendency to misalign. The bursting of the front wheels often leads to sharp biases, which can easily lead to crashes, ditching, and rollover accidents. Coping methods: If the tire suddenly bursts during driving, do not be alarmed. As long as you hold the steering wheel with both hands, you can still control the vehicle. If it is a rear tire burst, the tail of the vehicle will oscillate and bump. As long as the driver stays calm, holding the steering wheel with both hands will usually keep the car in a straight line. In addition, it is best to step on the brake pedal repeatedly, so that the center of gravity of the car can be moved forward and the intact front tire can be forced to relieve the load on the burst rear tire. Also be careful not to step on the brake pedal excessively. If you burst the front tire, the situation is much more serious. The brake pedal should be lightly pressed as much as possible to avoid too much force on the front part, because the front tire that bursts will roll unevenly and may even get out of the rim. Hold the steering wheel tightly with both hands and correct immediately if the vehicle is sharply to the left or to the right. The car tire suddenly falls off while driving If the farmer does not pay attention to the daily maintenance of the agricultural vehicle and the inspection before driving, when the wheel fixing nut is loosened, the vehicle's tire may suddenly fall off while driving, and the entire vehicle will lose its balance. If the front tires fall off, the exposed axles, brake drums, etc., will poke into the ground to form a fulcrum and become a turning center, which may cause the vehicle to turn over and cause a rollover. If the rear tires fall off, the degree of slewing is less severe. When the agricultural vehicle encounters such a situation while driving, the farmer should apply an emergency brake and immediately turn the steering wheel in the opposite direction of the car's rotation. Sudden failure of braking during driving Although the probability of brake failure in agricultural vehicles is very small, statistics from the Traffic Police Department show that the traffic accidents caused by the failure of the brakes account for more than 20% of the total traffic accidents, and are mostly serious traffic accidents in which vehicles are destroyed. When driving, if you find that the vehicle is out of service, you should try to stop it as soon as possible according to the road conditions. If it is found that there is an obstacle in front of the vehicle that is in urgent need of evacuation, the farm hand should quickly use the parking brake. The correct method is: slowly pull up the handbrake, take a few times to tighten, loosen, tighten, loosen the method to slow down the vehicle, avoid pulling the hand brake too fast, otherwise, will cause the handbrake wire rope because of excessive force However, when the hand brake is disabled or the rear wheel of the vehicle is locked, the vehicle is out of control. At the same time, it is necessary to grab low gears, make full use of the engine's deterrence to slow down the vehicle, and hold the steering wheel firmly. In line with the principle of “first letting people make thingsâ€, avoid dangerous targets and drive to the roadside safe parking. If a brake failure is found during normal driving, if there is no special situation in front of it, you can decelerate it and then switch back to the low gear, observe the surrounding conditions, and use the road surface, uphill, road bank, sand and mud pile etc. with high resistance as much as possible. Slowly stop the car. If the situation is very urgent, such as brake failure in dangerous road sections such as downhill and turning, to prevent the further expansion of the danger, while pulling the handbrake and grabbing the low brake, attention should be paid to the control of the direction, and it can be determined decisively in the last resort. Use roadside farmland, sand fields, sand mud piles, haystacks, road trenches, woods, trees, rocks and other obstacles to stop the vehicle from driving. Sudden skidding on the way The reasons for the sudden slippage of agricultural vehicles during driving are as follows: First, they come from roads, such as ice and snow, muddy roads, and bends, ramps, uneven roads, and over arched bridges; the speed is too fast; Driving, such as emergency braking, sudden acceleration, deceleration, or struck the steering wheel; the third is from the vehicle, such as tire pressure does not meet the requirements, uneven front and rear brakes, tire tread wear equal. In the event of a sudden slip in the course of driving agricultural vehicles, the key actions are: reduce the throttle, reduce the speed, and correct the steering wheel in the direction of the sideslip. Must pay attention to try not to use the brake when skidding, it is forbidden to brake the car with one foot. When it is necessary to use the brake, it is necessary to use the point brake, because one foot will brake the car and make the wheel locked. Also pay attention to keep the clutch engaged and decelerate using the engine brake. When driving agricultural vehicles, in order to prevent slipping, you should try to avoid sudden braking, especially when braking on wet roads. When driving on icy and snowy roads, the vehicle must be started, stopped and turned slowly. It must be used when braking. Stop the brakes to avoid the brake on one foot. When driving on curved roads, ramps, uneven roads, and crossing arched bridges, the speed must be slowed down and the speed of driving should not be exceeded. Car spontaneous combustion during driving Before the agricultural vehicle in motion is ignited due to accidents or illegal operations, it usually has early warnings. If abnormal sounds, odors are noticed, smoke is seen, etc., it is necessary to slow down and stop at the same time. The vehicle can be parked in a sheltered area), cut off the oil circuit, close the tank switch and shutters, leave the cab and carefully look for the ignition point. If spontaneous combustion occurs, there is usually a period of time from the smoke to the open flame. At this time, the farmer must not panic, as long as fire extinguishers can be used, or water, sand, wet cotton quilts, tarpaulin, etc. can be used to extinguish the fire; If you cannot control the fire, you should call 119 immediately. In addition, special attention should be paid to the following three points: First, if there is a flammable material, high-tension line, parking lot or gas station where there is a fire, the vehicle should be moved to a safer area before the fire is extinguished. Second, when the fire is extinguished, self-protection should be taken care of. Because of eagerness to rescue the property on the vehicle and cause burns and burns, and do not breathe or shout loudly and cause the pyrotechnic burn to the upper respiratory tract; Third, the fire prevention and explosion protection of the fuel tank must be well done. The onlookers should be evacuated in time to avoid the occurrence of fuel tank. The explosion caused more damage. Driving on the road "speed car" "Speeding" means that the speed of the diesel engine suddenly rises, and it exceeds the nominal speed so much that the engine vibrates violently. At this time, the exhaust sound of the diesel engine is getting denser, and the exhaust pipe emits black smoke or blue smoke in a large amount, and reducing the throttle can not reduce the rotation speed. If no emergency measures are taken, “speed racing†will not only cause the bolts of diesel engine connecting rods to break and damage cylinder heads, airframes, pistons and other parts. At the same time, there will also be major accidents such as flywheel cracking, valve and valve spring breakage, and even direct threat to agricultural operators. Personal safety. Although there are many reasons for causing "speed racing," they can basically be divided into two categories: First, fuel oversupply, and second, burning oil. When the “carriage†phenomenon occurs while the agricultural vehicle is driving, the farmer should be in no danger and calmly adopt an effective method. It is possible to increase the load while the high gear is being applied, and depress the brake to reduce the engine speed and extinguish the engine helium. At this time, it is forbidden to depress the clutch pedal. Otherwise, the "flying car" will be exacerbated due to the no-load operation of the engine, and the consequences will be more serious. In the diesel engine "speed" is stopped, the fault is excluded, it should also check whether the diesel engine parts due to "speed" damage. The wheel is vacant while driving When a farm vehicle runs, once the wheel comes out of the shoulder and the individual wheel loses its support in full or in part, the farmer should try to stop it as soon as possible. According to the site conditions, select the side that is safe without losing the balance and open the door and leave the cab. Observe the dangerous situation of the vehicle in detail and take corresponding measures according to the danger. If the vehicle has only one front wheel or one rear wheel is vacant, a stone can be placed in the appropriate position on the road surface as a support point for the lever. A long wooden stick is inserted into the suspension wheel and the principle of the lever will be used to make the suspension. In the wheel loop, if the vehicle is in danger of falling over a cliff, it should be fastened with a rope and fastened to a solid tree or stake on the roadside, on the building, and then quickly move the cargo to the vehicle. The vacant side to maintain the balance of the body, if necessary, to remove the goods and then take measures. In addition, if the slope at the road shoulder is small, you can also use methods such as placing planks and stones, or digging off the shoulders, so that the suspended wheels can gradually fall into the loop. Night driving headlight suddenly extinguished When driving at night, if the headlight suddenly goes out, you should immediately open the width indicator or the ceiling lamp of the cab, and safely and steadily drive the car to the side of the road to stop. If all the lights of the agricultural vehicle go out, you should try to control the driving direction (do not use the steering wheel), and let the vehicle move forward according to the original normal driving route. At the same time, stop the engine quickly and stop troubleshooting. After parking, the farmer can draw materials locally and use flashlights, candlelight, red or white clothing to set warning signs to prevent collisions with passing vehicles. If the fault can not be eliminated on the spot, and urgently need to hurry, you can use the moonlight and the trees on both sides of the road and press the horn to warn the agricultural vehicle to slowly approach the nearest repair point. Need to remind the farmer is that, with the moonlight driving should be clear: see the shiny surface, see the white is the road, see the mud is black. The vehicle slipped suddenly on the way uphill When a farm vehicle is seriously overloaded on an uphill slope, if the vehicle's sliding force exceeds the traction of the engine, if the shift fails, the vehicle will suddenly drop. When the agricultural operator encounters this condition, the handbrake and foot brake should be used at the same time. After parking, you should start padding with triangle wood, stones, etc. under the wheels. In the event that the hand brake and the foot brake are both braked at the same time and the vehicle cannot be controlled to slip backwards, it is necessary to control the direction, avoid dangerous targets on the road, and drive into roadside farmland and sand. In the most critical cases, roadside natural obstacles can be used to prevent the vehicle from sliding down. For example, the rear end can be brought close to natural obstacles such as mountains, rocks, and trees in the roadside, and the kinetic energy of the vehicle can be consumed to reduce the accident loss. The steering of the vehicle is out of control while driving When parts of the agricultural vehicle steering mechanism are detached, damaged or stuck, it may cause the steering mechanism to suddenly run out of control, making it impossible for the driver to control the direction. At this time, the agricultural vehicle rampages and once the farmer handles it improperly, it will destroy the vehicle. If this happens, the farmer should immediately lift the accelerator pedal, put the transmission into the low gear, and brake with a slow handle or brake with a foot brake. When the speed has dropped significantly, the foot brakes and the vehicle gradually stops. Of particular note is: when the vehicle is at high speed, do not use too much force on the foot brake, otherwise, the vehicle may slip sideways, leading to greater danger; also can not escape the slide; at the same time, regardless of whether the steering system is effective, Should be as far as possible to the steering wheel to the roadside or trees, rocks and other natural obstacles in order to make the car parked out of danger, do not think that the road conditions are good, on the lucky side, barely driving.
