The invention relates to a branched chain stop control type multi-degree of freedom (DOF) linkage mechanism which is composed of a prime mover, a transmission device and a multi-DOF linkage mechanism body. The transmission device is composed of a transfer case, a clutch, a reversing device and a speed reducer. The prime mover distributes motive power to all driving rods of the multi-DOF linkage mechanism body through the transfer case. Through the manual operation control of the clutch and the reversing device of the transmission device, the effect that all the driving rods are in a constant speed driving state can be achieved, and the effect that certain driving rods are in a static state, and the other driving rods are in the constant speed driving state can also be achieved. Under the cooperation action of the several states of the driving rods, the effect that the branched chain stop control type multi-DOF linkage mechanism can output complex and changeable moving trajectories is achieved; not only is cost lowered, but also an internal combustion engine can be used as the prime mover so that the problem that the branched chain stop control type multi-DOF linkage mechanism is limited by electric power supply when a motor is used for driving can be avoided; and the branched chain stop control type multi-DOF linkage mechanism facilitates field construction and is especially suitable for the field of excavators, the field of loaders and other fields.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a multi-degree-of-freedom link mechanism with branch chain stop control. Background technique [0002] The controllable mechanism can realize flexible output and improve the kinematic and dynamic characteristics of the mechanism. The current controllable mechanism is mainly divided into adjustable mechanism, variable input speed mechanism, electronic cam mechanism and mixed input drive mechanism according to the realization method. [0003] The adjustable mechanism mainly adjusts the relative length of the link mechanism or the relative position between the hinges to meet the requirements of kinematics. It can realize trajectory synthesis, motion synthesis and function synthesis, but most of the adjustable mechanisms stop when the motion is stopped. Manual step-by-step adjustment or automatic adjustment in the process has low controllability and poor practicability; the varia...
