The invention relates to the technical field of working vehicles, in particular to a telescopic arm of a working vehicle. Comprising a basic arm and a driven arm, and the driven arm is sleeved with the basic arm and can stretch out of the basic arm and retract into the basic arm; the device further comprises a motor, a driving sprocket, a driven sprocket and a chain. The motor is fixedly connected to the outer wall of the basic arm, the driving chain wheel and the driven chain wheel are installed at the two ends of the basic arm, the chain is installed on the driving chain wheel and the driven chain wheel, and the driven arm is fixedly connected to the chain. The motor is connected with the driving chain wheel, the motor drives the driving chain wheel to rotate, the driven chain wheel rotates along with the driving chain wheel, and the chain moves along with the driving chain wheel, so that the driven arm is driven to move, and the driven arm is driven to stretch out of the base arm and retract into the base arm. The movement stability is improved, the weight of the whole structure is reduced, the internal space of the arm body is not occupied, and the later maintenance cost is reduced.
本发明涉及作业车辆技术领域,尤其涉及一种作业车辆伸缩臂。包括基础臂与从动臂,从动臂套接在基础臂内,能从基础臂内伸出以及缩回基础臂;还包括电机、主动链轮、从动链轮与链条;所述电机固接在所述基础臂的外壁上,所述主动链轮与从动链轮安装在所述基础臂两端,所述链条安装在主动链轮与从动链轮上,所述从动臂固接在所述链条上;所述电机与所述主动链轮相连,电机带动主动链轮旋转,从动链轮随之旋转,链条随之移动,进而带动从动臂移动,带动从动臂从基础臂内伸出以及缩回基础臂。运动的稳定性得到提高,减轻了整体结构重量,不占用臂体的内部空间,而且降低后期维护成本。
