Description

Catamaran automatic connection device

technical field

The invention belongs to the technical field of automobile manufacturing and relates to a connecting device, in particular to an automatic connecting device for a two-body vehicle.

Background technique

With the continuous improvement of people's living standards, people pay more and more attention to the quality of life. Many people have cars, which provide convenience for people's travel.

At present, cars are monolithic cars. When running into narrow roads, automobiles cannot pass through, and need to find another road, which is inconvenient to drive. And now the universality of automobile often can cause the blockage of traffic road, but still can have narrow passage between each other automobile, because the volume and structure of automobile self, automobile just can not pass through above-mentioned narrow passage. Cars are blocked and cannot move, wasting time and delaying people's journeys.

Someone proposed the concept of a catamaran, which is a four-wheeled automobile formed by merging two separate motorcycles through a connecting device, but it has not been widely used in production because some technical problems have not been overcome.
