In recent years, with the continuous development of vehicle technology and tourism industry, the frequency of RV has become higher and higher. In particular, the emergence of the C6 driver's license has contributed to the rise of the trailer RV.

RV refers to a special vehicle with tables and chairs, sleeping utensils, cooking utensils, storage, bathroom, lighting, air conditioning and other facilities designed in the carriage. It is mainly used for tourism and camping for field workers. It is a mobile vehicle with necessary household facilities.

In the past, one-piece RV was common, that is, the cockpit and carriage were integrated. Trailer type RV is different. It is more like a carriage and cannot be driven alone. It needs to be driven with the help of the traction vehicle in front, such as pickup truck and passenger car. In this way, when the RV carriage is not available at ordinary times, the owner can separate the carriage from the tractor and use the tractor alone. When the carriage is needed, it can be connected together, which can improve the service efficiency of the vehicle to a certain extent.

In fact, this kind of RV is also called "Caravan". It belongs to a special trailer model, which is different from the ordinary vehicle driver's license. Only with an A2 trailer driver's license can such a car be towed. However, the driver's license regulations have been updated. If the total mass of the tractor and carriage is less than (not including) 4500kg, the C6 driver's license can be applied. As long as you can get the C6 driver's license, you can drive. If it exceeds 4500kg, you can only use A2 driver's license. At present, the design and specifications of many domestic light residential trailers can basically meet the driving requirements of C6 driver's license.

It is worth mentioning that at present, only users with A2 driver's license can be directly compatible with C6 without separate application. Other types of driver's license need to apply for additional driving to obtain a C6 driver's license for light towing trailers.

Recreational semi-trailer also includes different categories, and there are two main categories: semi-trailer recreational vehicle and center axle recreational vehicle. Although both types of vehicles are eligible for a C6 license, there are different requirements for their tractor categories.

Among them, the principle of semi-trailer residential trailer is similar to that of transport semi-trailer. It is with gooseneck and needs to be towed by saddle. Light trucks with connecting plates are required to be used as tractors, such as pickups. Passenger cars cannot be used as tractors.

The principle of the center axle RV is the same as that of the center axle semi-trailer. When the trailer is uniformly loaded, the mass center of the trailer is close to the axle position, the traction device cannot move vertically relative to the trailer, and only a small vertical load acts on the tractor when connected with the tractor, which can be towed by the passenger car.

Car owners can compare their travel trailer license to see if the registration of the model is accurate. It should be noted that no matter which model is used as the tractor, it must have the traction qualification.

With the gradual rise of caravans, the market demand for axles and axles of caravans also began to rise. Similar to the axle principle of the transport semi-trailer, the rear axle of the caravan is also a support axle, which does not have steering or driving functions, and is mainly responsible for loading, braking, maintaining driving and reducing the vibration of the carriage.

The difference is that the rear axle used by RV is much smaller than that of semi-trailer. At present, the tonnage of semi-trailer bridge with the widest demand in the market is about 13T, and the tonnage of semi-trailer bridge mainly focusing on lightweight is also about 10t. The rear axle tonnage of RV is generally less than 6T, such as 5T and 3T.

In addition to the smaller tonnage, there is no clear and unified standard reference for the parameters of the rear axle of RV, such as track width, which is relatively small. Most of them need to be customized according to the detailed requirements provided by customers. To a certain extent, it puts forward higher requirements for manufacturers' production experience, technology and process. Especially those brands that do not have special factories and purchase semi-finished products from outside for assembly and sales, I am afraid it is difficult to meet the customized needs of customers in terms of parameters.

From this point of view, when purchasing RV axles, try to choose brands with independent production capacity and quality assurance ability, which can not only customize the perfectly matched axles according to the customer's models, but also avoid or reduce many problems that may occur in subsequent use.

Darong heavy industry group is an enterprise engaged in the production and manufacturing of axles for more than 20 years. It has always focused on the R & D and production of axles and axles. It has made good achievements in the fields of high-strength axle beams, high-precision wheel ends, lightweight axles and customized production. Its products have passed the ISO9001 quality management system certification, and has established stable cooperative relations with many vehicle manufacturers, logistics companies, fleets and retail investors at home and abroad, Always keep a record of zero quality disputes.

In addition to the conventional semi-trailer drum axle, disc axle, low flat axle and special axle in the market, Darong 3t-8t customized small tonnage axle has also won wide welcome in the market and has been exported to Europe, America, Australia and other countries for many times, providing customers at home and abroad with a perfect customized axle one-stop solution.
