Spine bridge off-road vehicle chassis with automatic wheel adjustment

Abstract

The invention relates to a back-bridge off-road vehicle chassis with automatically-adjusted wheels, and belongs to the technical field of automobile manufacturing. The back-bridge off-road vehicle chassis comprises a back bridge for bearing a vehicle body, wherein a back-bridge front half shaft is installed at the front end of the back bridge. The front end of the back-bridge front half shaft is connected with a front-bridge swaying frame, and the rear end of the back-bridge front half shaft is connected with a front hydraulic swaying regulator. A back-bridge rear half shaft is installed at the rear end of the back bridge, the rear end of the back-bridge rear half shaft is connected with a back-bridge swaying frame, and a rear hydraulic swaying regulator is installed at the front end of the back-bridge rear half shaft. The front hydraulic swaying regulator is connected with the rear hydraulic swaying regulator through a hydraulic system, two sides of the front-bridge swaying frame are connected with front wheels, and two sides of the back-bridge swaying frame are connected with rear wheels. When the off-road vehicle chassis runs on a road surface with a large high-low difference, each wheel can automatically regulate the height so as to adapt to the uneven ground. In addition, when the vehicle runs, no matter which wheel is raised or lowered, the raising / lowering height of the vehicle are about one half of that of the wheel. Compared with the prior art, the vehicle is reduced by one half in the bumping degree, so that a driver and passengers are more comfortable.

Description

Technical field: [0001] The invention relates to the technical field of automobile manufacturing, in particular to a spine bridge off-road vehicle chassis with automatic wheel adjustment. Background technique: [0002] Modern cars pay more and more attention to ride comfort, so that consumers often regard car comfort as an important measure of water purchase. Especially for off-road vehicles, when traveling through mountains, canyons, deserts, and rainforest areas, if the wheels are driven on a road with a large difference in height, the wheels will slip due to uneven weight, or even hang in the air, thereby reducing the driving force of the wheels. Even lose propulsion, greatly reduce the passing capacity of the vehicle, and make the driver and passengers feel very bumpy and uncomfortable. The suspension system plays a key role in improving vehicle performance due to uneven road surfaces. [0003] Suspension system is a general term for all force-transmitting connection d...

Problems solved by technology

[0006] However, the off-road vehicle chassis with this structure still has certain limitations, and it can only eliminate the bumpy feeling when the road level difference is not very large, and the vehicle's ability to overcome obstacles is not very high.

When the vehicle is in the field, it often encounters a situation where the road surface has a large difference in height, the vehicle still feels very bumpy, the swing of the vehicle body is still large, and the vehicle cannot even cross the obstacle at all.
