A propulsion assembly for an amphibious wheeled vehicle

Abstract

The invention provides a propelling component for an amphibious wheel type vehicle. The propelling component comprises a propelling device and an oil cylinder, wherein the propelling device comprises a hydraulic motor and a propeller assembly connected to one side of the hydraulic motor; the propelling device is arranged on the tail of the amphibious wheel type vehicle, and the oil cylinder is mounted in a vehicle body of the amphibious wheel type vehicle; and the axis central position of the propelling device is hinged to the vehicle body of the amphibious wheel type vehicle, and one end, away from the propeller assembly, of the propelling device is hinged to a transmission rod of the oil cylinder. Compared with the prior art, the propelling component for the amphibious wheel type vehicle greatly improves water rapid maneuverability, landing efficiency and battlefield survivability of the amphibious wheel type vehicle, and meanwhile, the water floating time of the amphibious wheel type vehicle can be greatly shortened, so that sailing time is greatly shortened; and the physical output of personnel is reduced, and the continuous fighting ability of passengers is improved.

Description

technical field [0001] The invention relates to the technical field of water propulsion, in particular to a propulsion assembly for an amphibious wheeled vehicle. Background technique [0002] In the past, the water propulsion of amphibious wheeled vehicles mainly relied on tire paddling, which used the difference in the reaction force generated by the lower and upper parts of the rotating wheels in the water to drive the vehicle in the water, and its water speed was mainly determined by the amount of water pushed out by the tires and its speed. However, since the structure of the tire is determined by the road performance, the amount of water pushed out by the tire will not be large, and only a small movement speed can be obtained. The propulsion efficiency of tire paddling is only about 10%, which can only overcome the basic requirements of water resistance, and the water speed is about 3-5km / h. [0003] Due to the low speed of amphibious wheeled vehicles relying on tire ...

AI Technical Summary

Problems solved by technology

[0003] Due to the low speed of amphibious wheeled vehicles relying on tire paddling, the steering wheel cannot get enough lateral force, so the vehicle's maneuverability on water is not good, and it is difficult to maintain the direction of movement of the vehicle, even driving on rivers with low flow velocity It is also very difficult, and it can no longer meet the rapid and efficient combat requirements of our army in the new era and safeguard our country's maritime strategic interests.
