The principle of the application is as follows:
for the express logistics industry mainly using light cargo throwing, due to the particularity of cargos, express delivery is mainly based on paper boxes or packaging bags, the weight is not large, the occupied volume is small, and the maximum load limit value specified by a two-axle vehicle is 18 tons based on the GB1589 standard. With the same container volume space, if fruits, vegetables or steel products and the like are filled, the load basically and directly reaches 18 tons, and even exceeds 18 tons, and for express delivery, because the express delivery mainly occupies space, when the container is filled, the overall load is often not 18 tons, and even the maximum load is often only 15 tons to 16 tons, therefore, for the same container volume space, when the express delivery is transported, the maximum load limit of 18 tons is not fully utilized, and the transportation efficiency and the user income are inevitably reduced.
Based on this, after a great deal of research, the inventor of the present application finds that, for a cargo truck for transporting express delivery, when the maximum load per cubic meter of the cargo tank of the cargo truck is set to be less than 0.26 ton, and the volume of the cargo tank is divided by the first space volume to be greater than 0.68, the volume of the cargo tank can be greatly increased under the condition that the maximum load condition is satisfied, so that the number of the accommodated express delivery can be increased, the transportation efficiency can be improved, and the user profit can be increased.
For example: the height of a current 12-meter single-row two-axle cargo truck with a sleeping cab is limited to 4m, the inner length of a cargo box of the truck is 9800mm, the inner width is 2450mm, the inner height is 2650mm, and the volume of the cargo box is 63.62m3。
By adopting the scheme of the application, the maximum load limit value of the two-axle vehicle is 18 tons, and the volume of the cargo box is 18 tons/m/0.26 tons/m3＝69.23m3。
For the first space, the length of the first space is the total length of the vehicle minus the single-row sleeper cab, i.e. 12m-2.05 m-9.95 m, and the volume of the first space is 9.95m × 4.5m × 4 m-99.5 m3。
69.23m3/99.5m3The volume of the container can be up to 0.70 and is more than 0.68 by adopting the scheme of the applicationTo a limit volume.
At the same time, relative to the current 63.62m3The container volume of the present application is up to 69.23m3The volume of the cargo box is increased by 8.9 percent and 5.61m3By adopting the scheme of the method, the yield can be increased by 44880 yuan.
Generally, in the prior art, the leaf spring structure 2 includes more leaf springs, and generally, for the leaf spring structure 2 corresponding to the front axle, the leaf spring structure 2 includes eight main leaf springs 20; in the leaf spring arrangement 2 for the rear axle, the leaf spring arrangement 2 comprises ten main leaf springs 20 and eight secondary leaf springs 21. The leaf spring uses too much for the space station position on vertical is big, the leaf spring stroke is big, thereby leads to the chassis too high, under the 4 meters condition of limit for height, must compress the packing box volume. Therefore, in this embodiment, in the leaf spring structure 2 corresponding to the rear axle, the leaf spring structure 2 includes four main leaf springs 20 and three auxiliary leaf springs 21, and in the leaf spring structure 2 corresponding to the front axle, the leaf spring structure 2 includes three main leaf springs 20, compared with the prior art, the space standing position of the leaf spring structure 2 in the vertical direction can be reduced, the leaf spring stroke is reduced, and the chassis height is reduced, so that more volume spaces can be provided for the cargo box.
