Nowadays, many self-media on the Internet and even some sales, will say: 1.6L or more displacement can tow. But in fact, the towing capacity needs to take into account the vehicle power, the vehicle's own weight, the rear suspension can withstand pressure and other factors. For example, some cars displacement more than 2.0L, but their own weight is relatively high, the power response itself is not very good, plus towing will lead to climbing effort, fuel consumption increased and so on. In addition, the rear suspension of some cars is relatively soft, when towing a trailer will lead to the main car rear suspension travel is overly compressed, the trailer body is not in a horizontal position, thus triggering the problem of poor driving stability.

For playing trailer caravan, the most recommended is the pickup truck, off-road vehicles such as non-load-bearing body, has a chassis beam model towing. Because the non-load-bearing body chassis beam is very strong, can better resolve the impact; at the same time, pickup trucks or off-road vehicles own weight is relatively large, you can better inhibit the impact of towing on the front of the car; in addition, pickup trucks or off-road vehicles, more than the use of integral bridge form of the rear bridge, in the load capacity is relatively better, can be used for towing some of the heavier caravans.

Such as SUVs, sedans can indeed be used to tow a caravan, but not necessarily suitable for towing a caravan, a lot of caravans, even if one or two people unarmed can also pull away. Many people may be curious: why many caravans in Europe are towed by cars? In fact, the overall development of the caravan camping industry in Europe is relatively early, the design of the caravan is also more mature, and the lightweight of the vehicle is more excellent. The general 7-meter body length of the European imported caravan, the vehicle weight is only in the 1100-1300kg or so. In addition, in the European region and North America are on the trailer caravan safety standards have clear provisions, requiring the main body weight of the trailer caravan by the center axle, and for the towing frame on the towing ball of the lower pressure also has clear requirements: the European standards generally require that the lower pressure of the towing frame is the trailer caravan of 7% of the weight, North America requires that in about 10%.

In addition, it is from the overall development of the caravan camping industry in the European region is relatively early, many European cars in the beginning of the design will take into account the situation of towing trailer caravans, in the rear bumper inside the hidden trailer ball head and power connector mounting position. Therefore, many European imported cars or some sedans or SUVs from European joint ventures have certain towing qualifications, which can be used to tow some light weight caravans with trailers. For example, the Elddis 550 pictured above has a total weight of 1,300kg and a maximum GVW of 1,500kg. According to the European standard for downforce, the downforce of the Elddis 550 in unladen and fully loaded condition is 91kg and 105kg respectively, which allows it to tow a Mercedes-Benz CLS (Configuration | Inquiries) sedan as pictured above. However, it should be noted that the specific ability to tow a caravan should also be checked in the vehicle manual.

What to pay attention to when towing a trailer

First of all, you need to pay attention to the weight ratio of the front and rear vehicles, the weight of the rear vehicle and the strength of the brakes to prevent the "folded head effect". The so-called "folding effect" means that the trailer pushes the tractor forward, resulting in the rear of the tractor to produce a certain degree of rotation, or even the situation of turning around. The "nose-over effect" usually occurs during emergency braking, downhill driving, or when steering while braking. The main reason is that the current trailer caravan braking system mainly has two kinds of brakes: crash brakes and electric brakes, no matter which one, are the main car first brakes, the trailer and then brakes, the front and rear of the car braking time interval is very small, generally in milliseconds or even microseconds as a unit; but there is still a time interval. Therefore, in the front and rear car brakes produce a time interval of a moment, the rear car will form a thrust on the front car. If the overall weight of the trailer is heavy, the front car may not be able to press the rear car. If it so happens that there is a certain angle deviation between the front and rear vehicles, the rear vehicle will cause the rear of the front vehicle to produce a certain magnitude of rotation, and may even cause the front vehicle to turn around directly. Therefore, in the use of trailer caravan, need to put as much material in the front car, reduce the weight of the rear car; and to minimize the heavy brake situation, thus preventing the "folded head effect".

In addition, you also need to pay attention to the trailer's front and rear weight ratios, driving speed, to prevent the "death swing". The so-called "death wobble" refers to the trailer caravan in the driving produced by the violent, high-frequency swaying left and right, when the swaying frequency reaches a certain value, may lead to loss of control of the vehicle. The main reason for "death wobble" is that it is affected by certain external influences, resulting in a change in the vehicle's equilibrium state. Generally encounter crosswinds, vehicle weight distribution is not reasonable, traveling too fast and other conditions will lead to changes in the balance of the vehicle. Therefore, in the actual use of the car process, we need to do our best to evenly distribute the material to the front and rear storage compartments, and connected to the trailer as far as possible to not more than 90km / h speed in high speed in the form. If the death swing has been generated, you can properly release the brake, and tap the gas pedal, so that the vehicle generates new forward momentum, so as to crack the "death swing".

Summarize: After the whole article, we do a small summary, trailer caravan is actually the front and rear cars composed of car train, so in the use of the process need to pay attention to relatively more matters. First of all, before departure, to reasonably distribute the weight of the items, check the trailer brake system, understand the weather conditions ...... and in the process of driving, we need to pay attention to control the speed, observe the road conditions in advance, and try to maintain a greater distance between cars than the usual driving.
