Description

technical field [0001] The present invention relates to dump trucks, in particular to dump truck rear vehicles. Background technique [0002] Existing mining dump trucks are generally composed of two parts, the front car and the rear. The front frame is used to support the front car, and the rear frame is used to support the rear car. The front frame is used to install diesel engines and generators. and other important equipment, the rear frame is used to support the cargo box. When the dump truck is loaded, the rear frame needs to bear a large gravity. In order to support the huge body structure, the rear frame and cargo box structure design should be reasonable. However, the unreasonable design and layout of the existing self-unloading rear vehicle frame and cargo box leads to a decrease in the load-carrying capacity of the self-unloading vehicle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rear car of ...
