Semi-trailer manufacturers tell how to drive in snowy days
How to drive in snow? 1. Choose the right tire: you can choose professional snow tires, which can exert excellent grip and drainage on ice and snow. If you encounter ice and snow on the way and cannot replace the snow wheels in time, you can deflate the truck tires to increase the contact between the tires and the ground and improve the tire's grip. 2. Avoid rushing directions: Avoid driving the steering wheel, accelerating, or braking when driving in the snow, and you should drive at a low speed as much as possible. Snowfall can cause snow on the road surface to freeze or muddy roads, which can reduce tire grip. If you are driving and encounter a vehicle skid, immediately release the throttle. Don't slam on the brakes, it will probably cause side slip. If a side slip has occurred, release the brake immediately to enable the steering wheel to regain control of the car. Slow steering. When turning, slow down first. Properly increase the turning radius and slowly turn the steering wheel. The steering wheel should be operated smoothly and smoothly, otherwise side slip will occur and the rear of the vehicle will be thrown out. 3. Do not refuel too hard: After the tire rotates at high speed, the adhesion to the ground will be reduced, and it is easy to slip. The truck driver must remember to slowly lift the clutch and lightly feed the oil. Usually, he starts in 2nd gear, and he can choose to start in 3rd gear to reduce torque. If slipping occurs at the start, immediately close the throttle fully and gently adjust the steering wheel to ensure that the vehicle is driving in the correct direction. 4. Do not change lanes frequently: Do not change lanes lightly and frequently. When you must overtake, you must keep a sufficient safety distance from the overtaking, and do not rush to return to the original road after overtaking. Instead, you must draw a sufficient distance from the following car before returning to the original road. 5. Utilize the inertial braking of the engine: low-speed slow travel is required on icy and snowy roads, make full use of the engine's 'drag' brake for deceleration, and maintain the adhesion between the wheels and the road through the engine's 'drag' brake Much better than using foot brakes. If you want to drive at a low speed, you must consider driving at a lower gear and keeping the engine at a slightly higher speed. If you gradually raise the throttle, you can get the engine brake. Regardless of whether or not the truck is equipped with ABS, it is better to pre-apply a few brakes before braking, which can remind the rear car to slow down to avoid rear-end collision. At present, many Dongfeng products have engine braking function. 6. Use snow chains to increase friction: I think I do n’t say that everyone knows the role of snow chains. After installing snow chains, it increases the friction between tires and icy roads, making driving more stable. Pay attention to the snow and ice. After the road surface, remove the snow chains in time, otherwise the tires will be greatly damaged. It is particularly worth mentioning that both the drive axle of the tractor and the rear axle of the trailer must be equipped with snow chains. Small snow chains solve big problems. 7. Pay attention to uphill and downhill slopes: When going uphill and downhill in snow, it is very dangerous. When going uphill, you must maintain a double distance with the car in front, and strive to complete the climb in one go. If the wheels slip due to ice on the ground when climbing, you can spread some sand or felt on the front and back of the wheels to increase the friction. If necessary, the hard ice on the ground can also be made into horizontal grooves with tools to avoid wheel slip. When going downhill, you must steadily shift to the first gear and use the low gear to reduce the speed.
