Problems solved by technology
In the existing vehicle chassis, since the drive axle is mostly an integral axle, and the suspension is mostly a leaf spring, this causes the vehicle to be greatly affected by the terrain when driving on a complex road surface, especially on road sections with many pits and ups and downs. The passing performance is poor and cannot meet the requirements of terrain passability

A special vehicle chassis comprises a vehicle frame, four drive axles with an identical structure and four sets of mounting supports with an identical structure, each set of mounting supports comprises two mounting supports, namely the first mounting support and the second mounting support, each drive axle is mounted between the first mounting support and the second mounting support of the corresponding set of mounting supports, the four drive axles are arranged in the length direction of the vehicle frame in sequence, the vehicle frame comprises a vehicle frame longitudinal beam, an independent suspension is arranged between each mounting support and the vehicle frame longitudinal beam, all the independent suspensions are identical in structure, the first mounting supports and the second mounting supports are identical in structure, the two sides of the bottom of the vehicle frame longitudinal beam are connected with the L-shaped bending portions of the first mounting supports and the L-shaped bending portions of the second mounting supports respectively, the two ends of each drive axle are mounted on the drive axle hole of the corresponding first mounting support and the drive axle hole of the corresponding second mounting support respectively, and a hydro-pneumatic spring is connected between a mounting support and a lower cross arm. The special vehicle chassis enables a vehicle to travel stably when the vehicle passes through complex rod surfaces, and is safe, easy to operate, simple in structure and convenient to maintain.
Description
technical field [0001] The invention relates to a vehicle component, in particular to a vehicle chassis. Background technique [0002] The special vehicle chassis is a special-purpose vehicle chassis based on heavy-duty vehicle technology that integrates the structure and functions of construction machinery and off-road vehicles. With the development of various branches of today's automobile industry, high reliability, high off-road performance, high maneuverability, high carrying capacity, energy saving and environmental protection, comfortable driving and riding, and good function expansion capabilities have become the development direction of new special vehicles. In the existing vehicle chassis, since the drive axle is mostly an integral axle, and the suspension is mostly a leaf spring, this causes the vehicle to be greatly affected by the terrain when driving on a complex road surface, especially on road sections with many pits and ups and downs. The passing performanc...
