Abstract

The invention relates to a high-precision, easily-assembled and easily-disassembled steering surface connection structure which is arranged on an electric steering engine. The connection structure comprises a steering shaft and a steering fork. One end of the steering shaft is connected with a steering engine rocker arm, and the other end of the steering shaft is provided with a steering shaft flange surface; one end of the steering fork is of a fork-shaped structure and is connected with a steering surface, the other end of the steering fork is provided with a steering fork flange surface; and the steering fork flange surface and the steering shaft flange surface are connected through a clamping groove and are firmly mounted through a fixing assembly, so that the steering engine rocker arm, the steering shaft, the steering fork and the steering surface are connected to be a whole. When the electric steering engine receives an instruction to drive the steering engine rocker arm to rotate, the steering shaft and the steering fork drive the steering surface to achieve deflection to complete predetermined actions. According to the steering surface connection structure, the disassembling and assembling process is easy to operate, the assembly manufacturability is good, the size is small, positioning precision is high, connection reliability is high, and the steering surface connection structure is suitable for connection between the electric steering engine which is small in size and large in load and the steering surface.

Description

technical field [0001] The invention relates to a rudder surface connection structure of an electric steering gear, specifically a high-precision, easy-to-assemble and disassemble rudder surface connection structure applied to an electric steering gear, and belongs to the research field of lightweight and miniaturized electric steering gears. Background technique [0002] The lightweight and miniaturized electric steering gear has the characteristics of small size and large load, and needs to withstand large torque and bending moment, and maintain a relatively high control accuracy. Therefore, the rudder surface connection structure of the electric steering gear must be required to have high precision and reliability. [0003] In the prior art, most high-precision rudder surface connection structures are relatively complicated, occupy a large space, and have many installation and disassembly steps. Therefore, there is an urgent need to propose a high-precision, easy-to-asse...
