Problems solved by technology

[0007] First, the torque is relatively small, which cannot meet the needs of large and medium-sized underwater robots for steering torque
[0008] Second, if you continue to use pure electric mode, the energy consumption will be high, and the energy carried by the battery cannot meet the frequent high-torque steering needs

Abstract

The invention relates to a steering gear, and particularly relates to a connecting rod type hydraulic steering engine. The connecting rod type hydraulic steering engine is suitable for underwater robots and other narrow-space marine vehicles requiring large torque. The connecting rod type hydraulic steering engine comprises a servo oil cylinder, an ear ring, a rudder tiller, a rubber rob, a copper bush and a rudder blade, wherein the servo oil cylinder is positioned in a marine robot carrier, an output end of a telescopic piston rod in the servo oil cylinder is provided with the ear ring, the copper bush is arranged on the marine robot carrier, the rudder rod penetrates through the copper bush, one end of the rudder rob is positioned in the marine robot carrier, and is connected with one end of the rudder tiller, the other end of the rudder tiller is hinged with the ear ring, the other end of the rudder rod is positioned on the outer part of the marine robot carrier, and is provided with the rudder blade, the rudder rod is rotated relative to the copper bush through the extension and the contraction of the piston rod, and the rudder blade is linked with the rudder rod. The connecting rod type hydraulic steering engine adopts the servo oil cylinder as the power source of the steering engine, and can provide the large torque output required by the steering of large and middle marine robots.

Description

technical field [0001] The invention relates to a steering device, in particular to a connecting rod hydraulic steering gear, which can be applied to underwater robots and other marine vehicles that require high torque but have small spaces. Background technique [0002] As an underwater observation and operation platform, underwater robots have been widely used in many underwater fields such as marine scientific research, marine engineering, marine resource exploration, and maintenance of reservoirs and dams. [0003] Underwater robots have very good flexibility and can realize six-degree-of-freedom movement in underwater space. Traditional underwater unmanned submersibles include AUV (autonomous underwater vehicle) and ROV (remotely operated underwater vehicle). ROV mainly relies on the vector arrangement of multiple propellers to realize six-degree-of-freedom movement in underwater space, while AUV mainly relies on steering to realize six-degree-of-freedom movement in un...
