Description

Technical Field

[0001] The utility model relates to the technical field of rescue vehicles, and in particular to a multifunctional amphibious rescue vehicle. Background Art

[0002] An amphibious rescue vehicle is a special vehicle designed for emergency rescue missions in complex environments. It combines the functions of land vehicles and ships, and can switch freely between land and water to adapt to various natural disaster rescue needs, such as floods, mudslides, urban waterlogging, and crossing waters after earthquakes.

[0003] Due to the suddenness, persistence and wide coverage of natural disasters, they pose a huge threat to humans, and their protection is extremely difficult. When a natural disaster occurs, rescue equipment needs to quickly carry supplies and rescue personnel to the disaster area to achieve rapid search and rescue of the victims. However, there are many shortcomings in existing rescue equipment. For example, inflatable rubber boats have problems such as small number of transport personnel, long inflation time, and slow movement speed. Alloy speedboats are difficult to transfer at any time and difficult to deal with water plants and undercurrents. At this time, the importance of amphibious rescue vehicles is reflected. However, due to the harsh natural environment, conventional amphibious rescue vehicles will be relatively affected during driving, slowing down their speed, resulting in them still occupying a large part of the time on the road during the rescue process. Time is very important for rescue work, and every second counts. Therefore, high-speed rescue is particularly important here.

At the same time, due to the setting of the differential 7, the connecting shaft 701 and the transmission shaft 702 realize transmission, and then cooperate with the planetary gear transfer mechanism 5 to realize the smooth straight running of the vehicle body 1. At the same time, the reducer 10 and the shock absorber 8 can also cooperate to ensure that the amphibious rescue vehicle can run normally, stably and reliably in the harsh environment.
