Abstract

Disclosed are an 8*8 off-road vehicle steering system and a steering method. Traditional large off-road vehicles have poor long-distance running capacity on roads which are muddy or soft or complex in road surface condition. The 8*8 off-road vehicle steering system is composed of steering oil cylinders (1), linear displacement sensors (2) and a control panel (3). Each steering oil cylinder is fixed to a chassis frame through two structural members (4). Hydraulic pressure is distributed to the steering oil cylinders through a distributor (5) and a pipeline (6). Each steering oil cylinder is provided with the corresponding linear displacement sensor. The steering oil cylinders are connected with steering rods (7). The steering rods are connected with suspensions through ball heads (8). The corresponding linear displacement sensor and each servo hydraulic pump (9) form a closed control system. A traveling computer matches angle data of a steering gear box (11) to the corresponding servo hydraulic pumps. The control panel is provided with a transmission control panel body and a steering control panel body. The steering method is suitable for the 8*8 off-road vehicle steering system.

Description

[0001] Technical field: [0002] The invention relates to a steering method for a steering system of an 8×8 off-road vehicle, which changes the driving mode of the existing long-wheelbase large off-road vehicle on complex road surfaces, and provides multiple means for crossing relatively deep waters. [0003] Background technique: [0004] Traditional large off-road vehicles have poor long-distance driving ability on muddy, soft or complicated roads. In order to meet the special needs of large off-road vehicles running on complex roads, the off-road vehicle steering system is designed. This system breaks through the barriers of the traditional off-road vehicle structure and proposes three steering modes, providing multiple means for large off-road vehicles with long wheelbases to cross unpaved roads. [0005] Invention content: [0006] The object of the present invention is to provide a steering method for a steering system of an 8×8 off-road vehicle. [0007] Above-mention...
