Overwater drag reduction mechanism for amphibious wheeled vehicle

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of amphibious wheeled vehicles, and in particular relates to an amphibious wheeled vehicle drag reduction mechanism on water. Background technique [0002] Due to the constraints of vehicle weight, external dimensions, power and other factors, it is difficult to increase the speed of the vehicle after it is launched. It is of great significance to study the drag reduction technology of vehicles and improve the speed of vehicles, especially combat vehicles. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the invention is: how to reduce the water navigation resistance of the amphibious wheeled vehicle. [0005] (2) Technical solution [0006] In order to solve the above technical problems, the present invention provides an amphibious wheeled vehicle drag reduction mechanism on water, which is arranged at the wheel well, which includes: ...
