In the present embodiment, the vehicle 1 may be a truck, particularly a minitruck for logistics transportation, for example, an express vehicle.

In the present embodiment, the vehicle body 10 includes the center sill 100, the floor 200, and the support frame 300, and the center sill 100, the floor 200, and the support frame 300 form a self-supporting structure. That is, the vehicle body 10 is a load-bearing vehicle body in the present embodiment. The bearing type car body means that the car body bears the whole car body, and the load of the car body is transmitted to wheels through a suspension assembly. The bearing type car body has high utilization rate of internal space, light weight, low gravity center, high stability and low energy consumption. The front frame and the rear frame of the bearing type car body can collapse when a collision accident occurs, so that the impact force is absorbed, and drivers and passengers in the car are protected, and therefore the safety is high.

According to yet another aspect of the present application, a vehicle 1 includes a vehicle body 10 and a chassis 20. The vehicle body 10 includes a floor 200 and a support frame 300. The chassis 20 includes a central spine 100 that extends generally longitudinally. The support frame 300 and the floor 200 are fixed to the center sill 100, the support frame 300 includes a bracket 310 and a support bracket 320, the bracket 310 is fixed to the center sill 100, and the support bracket 320 is fixed to the bracket 310.

Fig. 9 schematically shows a perspective view of a chassis according to an embodiment of the application. As shown in fig. 9, the chassis 20 includes a center keel 100 and a wheel set 600 secured to the center keel 100. Specifically, the wheel set 600 may include a front wheel set 610 and a rear wheel set 620. The front wheel set 610 is secured to the front end of the center keel 100 and the rear wheel set 620 is secured to the rear end of the center keel 100.

In this embodiment, the chassis 20 includes a center keel 100, and the support frame 300 and the floor 200 are secured to the center keel 100. That is, in the present embodiment, the vehicle body 10 is a non-load-bearing vehicle body. In a non-load bearing vehicle body, the chassis includes a center sill with high strength. Because the central keel has high rigidity and can well absorb and resist torsion force, the influence on the non-bearing vehicle body is obviously reduced when the vehicle passes over uneven pavement. Besides the buffer and shock absorption effects of the tire and the suspension system on the whole vehicle, a shock absorption material can be arranged between the central keel and the vehicle body to play roles of auxiliary buffer, proper absorption of torsional deformation of the vehicle frame and noise reduction, so that the service life of the vehicle body is prolonged, and the riding comfort is improved. The chassis and the vehicle body can be assembled separately and then assembled together, which simplifies the assembly process and facilitates the specialized cooperation of organizations.
