Unmanned obstacle crossing vehicle

Abstract

The invention discloses an unmanned obstacle crossing vehicle. The unmanned obstacle crossing vehicle comprises a vehicle frame and vehicle wheels mounted on the vehicle frame through suspensions; thesuspension comprises a front suspension and a rear suspension which are respectively located in the front and back of the vehicle frame and are in swinging connection relative to the vehicle frame, as well as a middle suspension located at the bottom of the middle of the vehicle frame and fixed relative to the angle of the vehicle frame; the front suspension and the rear suspension are in hingedconnection with the vehicle frame respectively through a front fork frame and a rear fork frame; and a swinging driving part is separately arranged between the front fork frame and the vehicle frame as well as between the rear fork frame and the vehicle frame. The unmanned obstacle crossing vehicle disclosed by the invention has the beneficial effects that the ground clearance of the vehicle frameand the axle distance between front and rear vehicle axles can be adjusted so as to be adapted to different obstacle crossing topographies, so that the passing ability of the unmanned obstacle crossing vehicle and the passing stationarity in the complex topographies is improved; the transmission efficiency is high, and good maneuverable capability and flexibility is realized.

Description

technical field [0001] The invention belongs to special vehicles, and in particular relates to an unmanned obstacle-crossing vehicle. Background technique [0002] Unmanned obstacle-crossing vehicles are mainly used for operations in special scenarios such as natural disasters, terrorist attacks, mine disasters and fires. In the above environments, it is often difficult to approach conventional operating equipment due to the limitations of terrain and environmental factors. The danger of special environments and the urgency of operations Sex also brings a huge crisis to the staff on the scene. Robots and unmanned vehicles are effective means to solve this problem. [0003] Maneuverability and obstacle surmounting performance are the basic performances of unmanned ground vehicles. Existing unmanned obstacle-crossing vehicles can be divided into wheel-type, leg-type, and crawler-type. Among them, the wheel-type has high efficiency and strong maneuverability, but its terrain ...

AI Technical Summary

Problems solved by technology

Existing unmanned obstacle-crossing vehicles can be divided into wheel-type, leg-type, and crawler-type. Among them, the wheel-type has high efficiency and strong maneuverability, but its terrain adaptability and obstacle-crossing ability are low; the leg-type has the strongest adaptability, but its efficiency is also low. The lowest; crawler type has good climbing ability and certain obstacle ability, but the efficiency is relatively low, and the maneuverability is poor
