The invention belongs to the technical field of amphibious wheeled vehicles, and particularly relates to an overwater drag reduction mechanism for an amphibious wheeled vehicle. The mechanism comprises a motor, a sealing cavity, a gear, a rack, a sliding plate, a guide mechanism and a sealing gasket. The sealing cavity is arranged at the front end of a wheel cabin in a vehicle body, and the open end leads to the wheel cabin of the vehicle body. The forward and reverse rotation of the motor can make the sliding plate extend out of the sealing cavity and retract. After the sliding plate extendsout of the sealing cavity, the hydrodynamic streamline vehicle body shape can be complemented. Therefore, a problem that when an amphibious wheeled vehicle sails on water, especially sails at a high speed, the hydrodynamic streamline of the appearance of the vehicle body is incomplete due to the existence of the wheel cabins is solved. When the amphibious wheeled vehicle sails on water, wheels canbe lifted to the position above the plane of the bottom of the vehicle, but part of a vehicle body of a wheel cabin is vacant, large resistance is generated during water navigation, and the water sliding state is difficult to achieve. The streamline shape of the vacancy at the bottom of the wheel cabin of the vehicle body under the overwater working condition can be complemented, the overwater navigation resistance of the amphibious wheeled vehicle is greatly reduced, and the overwater navigation speed is increased.
本发明属于水陆两栖轮式车辆技术领域,具体涉及一种两栖轮式车辆水上减阻机构。该机构包括电机、密封空腔、齿轮、齿条、滑板、导向机构、密封垫。密封空腔置于车体内轮舱前端,开口一端通向车体轮舱,电机正反转可使滑板伸出密封空腔外和收回。滑板伸出密封空腔后,可以补全水动力流线车体外形。本发明解决了两栖轮式车辆水上航行时,特别是高速航行时,由于轮舱存在而造成的车体外形水动力流线不完整的问题。两栖轮式车辆水上航行时,车轮可以提升到车底平面之上,但轮舱部分车体空缺,水上航行时将产生较大的阻力,很难达到水上滑行状态。本发明可补全水上工况时车体轮舱底部空缺的流线外形,大幅降低两栖轮式车辆水上航行阻力,提高水上航速。
