Abstract

The present invention relates to the field of helicopter control system design, in particular to a device for transmitting control motion, including: an input rod; a guide unit, one end of which is hinged to the input rod, and the other end is connected to a servo mechanism; a support for fixing The guide unit is supported; wherein, the driver's manipulation instruction is sequentially transmitted to the servo mechanism through the input rod and the guide unit. The device for manipulating movement transmission of the present invention can be used to transmit the displacement between the pull rods in the helicopter flight control system with a long line, and has a simple structure and small space occupation, and is especially suitable for the pull rods of the multi-channel control system in a limited space. Displacement transmission, and it is suitable for the layout of the steering system with a small angle between the input and output rods.

Description

technical field [0001] The invention relates to the design field of a helicopter control system, in particular to a device for transmitting control motion. Background technique [0002] When the helicopter control system is arranged on the helicopter, it is often limited by the surrounding body structure and other system components. The length of the tie rod of the control system on the large-tonnage helicopter is limited by the stiffness and strength. [0003] The control system of a large-tonnage helicopter has a long line, and the displacement transmission of the same channel needs to be completed by multiple tie rods. The rocker arm device is commonly used for the displacement transmission of the control system rod. The rocker arm device is generally composed of torsion shaft, rocker arm and bearing, and requires a large space. In particular, multiple channels of the control system are often arranged in a centralized manner, which involves the centralized arrangement of...
