Embodiment 1

[0050] In this embodiment, the sealed cavity 8 is installed in the car close to the wheel well, parallel to the plane of the bottom of the car, and the open end leads to the wheel well. After the slide plate 6 stretches out of the sealed cavity 8, the position can complement the wheel well of the car body. The hydrodynamic streamlined shape of the underside.

[0051] The welding between the guide mechanism 4 and the sealing cavity 8 should be intact, the sealing screw should be tightened with sealant, and there should be no leakage in the air tightness test. A guide mechanism 4 should be installed at intervals along the length direction of the slide plate 6 to prevent the slide plate 6 from running off track or stuck under the action of gravity or water resistance.

[0052] After the slide plate 6 is fully stretched out, a positioning clamping mechanism should be provided on the car so that the slide plate 6 will not be deformed, dislocated or fall off due to the force of the ...

Abstract

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. The mechanism includes a motor, a sealed cavity, a gear, a rack, a slide plate, a guide mechanism and a sealing gasket. The sealed cavity is placed at the front end of the wheel well in the car body, and one end of the opening leads to the wheel well of the car body, and the forward and reverse rotation of the motor can make the slide plate extend out of the sealed cavity and be retracted. After the skateboard protrudes from the sealed cavity, it can complement the shape of the hydrodynamic streamlined car body. The invention solves the problem of incomplete hydrodynamic streamlines of the vehicle body shape due to the presence of wheel wells when the amphibious wheeled vehicle sails on water, especially at high speed. When the amphibious wheeled vehicle sails on water, the wheels can be lifted above the bottom plane of the vehicle, but part of the vehicle body in the wheel well is vacant, and large resistance will be generated when sailing on water, making it difficult to reach the state of water gliding. The invention can complement the vacant streamline shape at the bottom of the wheel well of the car body in the water working condition, greatly reduce the water navigation resistance of the amphibious wheeled vehicle, and increase the water speed.

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 solutions [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:...
