Problems solved by technology

However, the single-engine solution requires a large engine power, which requires a large-volume engine and a corresponding large-volume transmission system or a high-power generator, which takes up most of the interior space and imposes a burden on the center of gravity of the vehicle. Difficult to come, the vehicle's economy and water stability are low

Embodiment 3

[0067] Based on the amphibious vehicle provided in Example 2, further, the water jet propulsion device and the components of the supporting drive system have the same specifications, the same parameters, and the same installation method, and are symmetrically installed at the rear of the vehicle body. The center of the device should be at the same angle between the center of gravity and the longitudinal centerline of the vehicle body to ensure that the center of gravity of the vehicle is located on the longitudinal centerline of the vehicle as much as possible, providing certain convenience for the arrangement of the center of gravity and ensuring the stability of the vehicle on water.

[0068] Further, the water jet propulsion device can realize the steering of the vehicle by adjusting the magnitude and direction of the water outlet thrust of the two water jets (the first water jet 13 and the second water jet 19 ).

Abstract

The invention belongs to the technical field of amphibious vehicles, and discloses an amphibious vehicle driving system using double water-jet propellers, a method and application. The amphibious vehicle drive using the double water-jet propellers comprises the steps that a water propulsion system directly drives the corresponding water-jet propellers to synchronously rotate through power output by output shafts of double engines so that the vehicle can run on the water; a tandem hybrid power driving system is utilized, and the output end of an engine is connected with a generator to supply power to a power battery pack and supply energy to front and rear axle drive motors to drive the vehicle on land. The double-engine scheme is adopted, the output power and the size of a single engine are reduced on the premise that the requirement of the whole vehicle is met, meanwhile, the engines are adopted to directly drive the water-jet propellers on the two sides, water driving is achieved, and meanwhile the double water-jet propellers are adopted, so that the vehicle arrangement flexibility is improved; in this way, water steering of the vehicle can be achieved through the water outlet thrust and the water outlet angle of the water-jet propeller in the water running process of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of amphibious vehicles, and in particular relates to a driving system, method and application of an amphibious vehicle utilizing dual water jet propellers. Background technique [0002] The amphibious vehicle is a new type of vehicle that can travel on water and land, with both the land performance of a car and the water drive performance of a boat. In scenes with complex land and water terrain, it can cross rivers, lakes and seas without being limited by bridges and ships, and can play its transportation function in both military and civilian fields. It has broad application prospects in special fields such as disaster relief and rescue. certain applications. [0003] The specification of Chinese patent CN110802989A discloses an amphibious vehicle adopting a hybrid scheme. A single engine is not only used to drive a single water-jet propulsion to achieve water-driven driving, but also can be used together ...
