According to China's current classification standards for automobiles: Trucks are divided into micro-trucks, light trucks, medium-sized trucks, heavy-duty trucks, and super-heavy trucks according to their tonnage. Mini trucks: The total mass is less than 1.8 tons. Light truck: The total mass is 1.8-6 tons. Medium trucks: The total mass is 6-14 tons. Heavy trucks: The total mass is 14-100 tons.
Due to the purchase tax of mini trucks during the purchase process, operating management fees (monthly/yearly) during use, and the cost of passing bridges, it is lower than light trucks, and the selling price is also lower by N than that of light trucks. The addition of "Sichuan" is also a little more exquisite, and is supplemented by many models that have been converted into various types of special vehicles, so it is widely welcomed by the market. Over the years, mini trucks have seized the market share of light trucks in order to be able to pull goods, and they have evolved from a single round to a later two rounds. Major changes have taken place in the frame, rear axle and suspension systems, and with light truck structures. similar. The most representative models of these two-wheeled mini-trucks are Beiling Foton, Chang'an Crossing King, Wuzhen Auto Aowei and Mianyang Jinbei Western Cowboy.
The maximum dimensions of the length, width and height of this type of rear two-wheeled mini truck are generally 5475 mm \1760 mm \2570 mm. The maximum wheelbase size is generally 2850 mm, and the maximum curb weight is generally 1675 kg. Technically the maximum allowable full load The quality is generally 3250 kg. Engine displacement will not exceed 2.0L. If you compare the technical standard parameters of light trucks and rear two-wheeled mini trucks, there is still a considerable gap. After all, the price is clear, and the price is a piece of goods.

In the recent market research, the author found that once the user purchases the rear two-wheeled mini truck, he will not perform it according to the technical standards in the specification. It is also commonplace to pull 4-5 tons at ordinary times. thing. Although at the time of design, the manufacturer has already reserved an overload factor for it, but in actual delivery, the user will not care about this one. It is always the user's demand for trucks. However, due to the problem caused by over-limit overloading, the user thinks that it is a quality problem. Therefore, disputes with the sellers continue to occur. Production vehicle manufacturers also have headaches. If a lawsuit is brought, the manufacturer can't come up with the fact of proof, and it is often the users of the so-called “weak†groups that win the case and compensate for the losses. In the event of an accident that caused car crashes due to overloading, it seems that the manufacturer is not able to take off. Since production car companies can develop and produce such models, they should also be responsible for such widespread problems.

The author often hears complaints from users in his market research that if he overloads more than 5 tons, he can't pull it, and the twisted deformation of the frame and the non-independent rear suspension of the leaf spring breaks or decouples. Tilted wheels interfere with the frame. Therefore, some users require the manufacturer to add an additional set of secondary springs. Some users found a roadside shop and replaced it with an old leaf spring removed from the light truck and continued to exceed the overload limit regardless of life safety. These users think that pulling only 5-6 tons of goods cannot be pulled because of poor quality. They do not think that the displacement of this vehicle is less than 2.0L. It is a "little horse-drawn cart." Of course, it cannot be moved. Now. Due to overload caused by leaf spring fatigue fracture is caused by the quality is not good, this kind of fallacies and the whole manufacturer nervous breakdown.
The above is a major problem caused by over-limit overloading during the user's use. It is not a problem caused by quality. However, in recent years, the author has found in the market and product research of mini-trucks that users have also put forward some relatively reasonable suggestions worthy of the attention and improvement of micro-car production car companies. If the length of the rear suspension is longer and the size of the container is lengthened, the tailing phenomenon will often occur when the goods are loaded or when driving on rugged mountain roads. Since the car companies set aside an overloaded space during the design process, they should proceed from the actual conditions in the market, and then increase the shaft moment accordingly to move the rear axle backward, so that the center of gravity will be more balanced after being moved backwards, and will no longer occur. Tail phenomenon.
At the same time, a slight increase in engine power, an increase in leaf springs, and a slight increase in the thickness of the frame were also reasonable claims, and an increase of 3,000-5,000 yuan. The users were also considered acceptable in the interview. Since all major mini-vehicle manufacturers have spent huge sums of money to develop and produce the two-wheeled micro-cards, they should be responsible for their markets and products, and they must always target their prospective customers before, during and after sales services. Users and users have repeatedly and repeatedly promoted the dangerous hazards of over-limit overloading. They must not care less about the dangers of unreasonable use of cars due to low vehicle prices, so that behaviors that are not responsible to people are repeated.
