Folding hydrofoil device of running system of evasive crawler-type amphibious vehicle

Abstract

The invention discloses a folding hydrofoil device of a running system of an evasive crawler-type amphibious vehicle. When the amphibious vehicle sails in the water, the hydrofoil device is driven by a hydraulic cylinder to be unfolded, and a flat plate connected with a folding mechanism is used as a hydrofoil, thereby increasing the upstream area of the amphibious vehicle travelling in the water, improving the lift borne by the amphibious vehicle, enabling the amphibious vehicle to rise from the water as quickly as possible, indirectly reducing the resistance borne by the amphibious vehicle, and improving the cruise speed. When the amphibious vehicle travels on the ground, the hydraulic cylinder retracts, the folding mechanism is retracted under the auxiliary action of a spring, and the flat plate is in an upright state parallel with the side of the vehicle body and can indirectly protect the mobile devices of the amphibious vehicle. Because a connecting rod between the hydraulic cylinder and a beam is eliminated, the evolution mechanism can prevent the mobile devices such as the crawler and the like from generating interference and can meet the requirement of compact assembly of the running devices of the amphibious vehicle.

Description

technical field [0001] The invention relates to a folding hydrofoil device for avoiding the action system of a crawler-type amphibious vehicle, in particular to a folding hydrofoil device suitable for amphibious vehicles running at high speed on water. Background technique [0002] With the development of modern warfare, landing operations urgently need to quickly transport soldiers from water (generally sea) to land, and overcome coastal obstacles to achieve successful landing. Tracked amphibious vehicles have this function, but due to their large body weight and relatively small body volume, it is difficult to realize fast driving on water. However, with the development of engine technology and water-jet propulsion technology, engines and water-jet propellers that can provide high power and high propulsion have been developed. If combined with a reasonable car body design, it has become an important technology for amphibious vehicles to travel at high speed on water. poss...

Problems solved by technology

This scheme is more convenient to implement, but it also has relatively large disadvantages

One is that the use of hinges to fix the hydrofoil plate will limit the immersion depth of the hydrofoil plate. When the plate is not underwater, it is in a sliding state. The second is that high-speed amphibious vehicles are mostly used for sea landing operations and transporting soldiers. When the sea waves are relatively large, because the plate is immersed in the water to a small depth, the vibration of the vehicle is relatively large, and the members feel very uncomfortable.
