Abstract

The invention relates to a frame assembly mechanism and a vehicle, and the frame assembly mechanism can be applied to the vehicle. The frame assembly mechanism comprises a frame longitudinal beam, a first cross beam and a second cross beam. The first cross beam and the second cross beam are arranged on the frame longitudinal beam in a spaced mode in the extending direction of the frame longitudinal beam, the frame longitudinal beam is provided with a frame tail, the second cross beam is located at the frame tail, and the second cross beam is made of a reinforcing plate, so that the torsional rigidity of the tail of the frame assembly mechanism is improved. In addition, the frame longitudinal beam is also made from a reinforcing plate, so that the bending rigidity of the frame assembly mechanism is improved. The rigidity and the pressure bearing degree of the frame assembly are improved through improvement of the torsional rigidity and the bending rigidity, in the actual design process, a compartment assembly can be directly installed on the frame assembly mechanism, the performance requirement of the whole vehicle can be met, other frame structures do not need to be designed for assisting in pressure bearing, and therefore the whole vehicle height of the vehicle is reduced, the gravity center of the vehicle is lowered, and the safety of the vehicle is greatly improved.

Description

technical field [0001] The invention relates to the technical field of commercial vehicle chassis, in particular to a frame assembly mechanism and a vehicle. Background technique [0002] With the development of commercial vehicle vehicle technology, the safety requirements of the vehicle are gradually increasing. As the main structural part of the vehicle, the frame assembly mechanism bears the loads of other sub-components and goods, causing the frame to bear the effects of gravity, impact load, torsional load and alternating load at the same time, so the frame is required to have a good strength and reliability. [0003] At present, most of the mainstream medium and heavy dump trucks are composed of a complete vehicle chassis and a bodywork system. The bodywork system generally includes a car body assembly and a sub-frame assembly mechanism. The car body assembly is connected to the frame assembly mechanism through the sub-frame assembly mechanism, so that the frame ass...
