Hydraulic system of amphibious vehicle

Abstract

The invention discloses a hydraulic system of an amphibious vehicle. The hydraulic system comprises a hydraulic oil tank and a plurality of track driving branches. Each track driving branch comprises a gear pump, a control valve and a track rotating mechanism, and the hydraulic oil tank outputs hydraulic pressure to the track rotating mechanisms after sequentially passing through the gear pumps and the control valves. The track rotating mechanisms are driven by the hydraulic pressure to drive the track to rotate. The control valve is used for receiving a signal of the whole vehicle controller to be opened and closed. Each gear pump is connected with an engine, and the engine outputs power to drive the corresponding gear pump to rotate. The hydraulic system of the amphibious vehicle has the advantages that the hydraulic system is adopted to drive the track to rotate, safety and reliability are achieved, meanwhile, the whole vehicle operation power is provided in the way of the track and wheels, and the device can be better adapted to various responsible driving working conditions. And meanwhile, hydraulic heat dissipation control is achieved through hydraulic heat dissipation, heat dissipation of oil can be effectively controlled, and it is guaranteed that the temperature of the oil hydraulic system is kept at a safe position.

Description

technical field [0001] The invention relates to the driving field of amphibious vehicles, in particular to a hydraulic system of an amphibious vehicle. Background technique [0002] The traditional amphibious vehicle uses a wheel-wheel system and a water jet propulsion system as the transmission system to provide power support for the amphibious vehicle to operate on water and land. Although this method can also meet the needs of amphibious driving, when driving on tidal flats at the junction of waterways and on ground with soft support surfaces, there are certain defects in using only tires to drive the vehicle, and the fast-moving ability is poor, so the crawler is added. It is a feasible way to improve the rapid lifting capacity at the junction of waterways with wheel-track composite drive wheels. Due to the structure and working principle of the track drive wheel system is relatively complicated, the selection of hydraulic system can reduce the crawler drive. complexity...

Although this method can also meet the needs of amphibious driving, when driving on tidal flats at the junction of waterways and on ground with soft support surfaces, there are certain defects in using only tires to drive the vehicle, and the fast-moving ability is poor, so the crawler is added. It is a feasible way to improve the rapid lifting capacity at the junction of waterways with wheel-track composite drive wheels. Due to the structure and working principle of the track drive wheel system is relatively complicated, the selection of hydraulic system can reduce the crawler drive. Complexity, but there is no related hydraulic system solution in the prior art
