Problems solved by technology

In addition, under complex and harsh road conditions, if skid steering is adopted, tracked vehicles will face problems such as excessive slip rate, vehicle deviation, difficult steering, and poor stability during driving.
The curved track steering method is limited by the flexibility of the track itself, the steering process requires a large turning radius, and the steering performance is poor
The current cutting-edge steering system includes the electro-hydraulic steering system, but there are many difficulties in the design of the electro-hydraulic steering system, such as the nonlinear characteristics of the electro-hydraulic system, the dead zone that changes with the load, asymmetric nonlinear gain and hysteresis delay, saturation, etc. characteristic

Abstract

The invention discloses a crawler type all-terrain vehicle articulated steering device and belongs to vehicle connection and steering devices. The articulated steering device is connected with a front module vehicle body and a rear module vehicle body and comprises a front module support assembly, a front hydraulic shock absorber assembly, a front fixing pin, two steering hydraulic cylinders, a bell housing front support, an articulated rotating pin, a bell housing, a rear fixing pin, a bell housing rear support, a rear hydraulic shock absorber assembly and a rear module support assembly. According to the articulated steering device, the limitation that a traditional double-section vehicle is difficult to turn and inconvenient to operate and cannot achieve pitching is overcome. By the adoption of the articulated steering device, the cross country capacity and trafficability of a vehicle are remarkably enhanced; and furthermore, through the front hydraulic shock absorber and the rear hydraulic shock absorber, the operation smoothness and driving comfort of the vehicle are guaranteed.

Description

technical field [0001] The invention relates to a vehicle steering device, in particular to an articulated steering device for a crawler-type all-terrain vehicle. Background technique [0002] my country has a vast territory, complex terrain, numerous lakes, rivers, and swamps, and frequent natural disasters such as floods, landslides, and forest fires. Relying on traditional vehicles is difficult to reach the accident site in time, and often misses the best time for rescue, causing serious losses to the country and the people. [0003] Tracked all-terrain vehicles are mainly used for personnel and material transportation and emergency rescue under various complex and harsh road conditions, which determines that they must have strong off-road capabilities and excellent maneuverability. Steering performance is one of the main indicators for evaluating the performance of tracked all-terrain vehicles, so it is of great significance to study the articulation device with good st...
