The invention provides a crawler-type vehicle power air cushion walking device. An engine nacelle is arranged at the front part of a vehicle body of a crawler-type vehicle and a ducted fan engine is mounted in the engine nacelle, so that the airflow sprayed by the ducted fan engine is steered and compressed by the inclined armor of the crawler-type vehicle to form a power air cushion among the bottom deck of the crawler-type vehicle, the two tracks and the ground and is sprayed backwards, and the pressure of the vehicle body to the ground is reduced by utilizing the power air cushion pressurization phenomenon in the ground effect. The power air cushion walking device can well balance the action capacity and the vertical obstacle crossing capacity of the crawler-type vehicle on soft ice andsnow surfaces and marsh beaches, and enables the crawler-type vehicle to have good amphibious capacity, and a relatively simple structure is guaranteed.
本发明提出一种履带式车辆动力气垫行走装置,包括在履带式车辆的车体前部设置发动机短舱,在发动机短舱内安装涵道风扇发动机,使得涵道风扇发动机喷出的气流经过履带式车辆的倾斜装甲转向压缩后,在履带式车辆的底甲板、两条履带和地面之间形成动力气垫并向后喷出,利用地面效应中动力气垫增压现象,降低车体对地面的压强。本发明的动力气垫行走装置能够较好地平衡履带式车辆在松软冰雪面和沼泽滩涂上的行动能力以及垂直越障能力,并且使得履带式车辆具有较好地两栖能力,还能保证相对简单的结构。
