Background

The traditional armored vehicle is limited by special conditions such as functions, use requirements, overall dimensions and the like, the technology of mature military off-road vehicles is less adopted, most of large assembly parts are brand-new developed, the technology of mature military off-road vehicles is adopted, the multi-aspect limitations of space size, overall arrangement and function use need to be broken through, and higher requirements are provided for the design of a bearing type armored vehicle body.

Secondly, the military off-road vehicle has the advantages that the bottom is completely open, the requirements for heat dissipation performance of parts in the design process are not high, the bottom of the bearing type vehicle body is closed, the working environment is severe, the requirements for heat dissipation performance of the parts are high, and the cooling is designed in a targeted manner if the military off-road vehicle mature assembly and the parts are adopted.

Disclosure of Invention

The invention aims to design and develop an armored vehicle body bottom structure capable of matching and integrating mature assembly parts of military off-road vehicles, aiming at the problems that most of the existing armored vehicle assembly is brand new development, and has high research and development cost, long period and low reliability.

The invention relates to a bearing type armored vehicle body bottom structure, which cancels a bottom plate of a traditional armored vehicle body, wherein integral longitudinal beams are designed on two sides of the bottom, a frame structure is formed by connecting a first longitudinal beam, a second longitudinal beam and a third longitudinal beam at axle positions, a front axle transmission shaft supporting point and a transverse beam according to stress strain conditions, two transverse beams are arranged at each axle position, the total number of the transverse beams is 12, the transverse beams are connected with the longitudinal beams in a bolt connection mode, the longitudinal beams are welded with the vehicle body, the longitudinal beams are made of 510L, the transverse beams are made of Q345 square steel pipe profiles, the cross section sizes of the front and rear transverse beams of a bridge are 80mm multiplied by 5mm, and the cross section sizes of the rest transverse beams are 60mm multiplied by 60mm by 5 mm. The bottom closed structure of the traditional armored vehicle is changed into an open frame structure.

The automobile engine, the speed changer, the power take-off device, the steering gear, the axle, the transmission shaft, the oil tank and the pneumatic system are arranged above the cross beam, the bottom is kept open, high temperature and high heat generated during the working of the moving part are directly cooled and dissipated under natural conditions, the cooling design is not required to be improved or increased, daily inspection and maintenance of each part are directly checked visually, the disassembly is reduced, and the maintenance difficulty is greatly reduced compared with that of the traditional armored vehicle.

The invention solves the problem that the chassis mature assembly component of the military off-road vehicle is arranged and installed on the bearing type armored vehicle body; the problem of cooling and heat dissipation after the power and transmission system mature assembly component of the military off-road vehicle and the bearing armored vehicle body are installed is solved; the problem of traditional formula armoured vehicle chassis part of bearing maintain the maintenance degree of difficulty big is solved.
