Embodiment Construction

[0019] A steering gear torque compensation mechanism that reduces the torque of the rudder surface, such as figure 1 As shown, they are respectively connected to the steering gear and the steering surface, and the torque of the steering surface is compensated by using the force generated by the elastic element to drive the roller to press the curved surface connecting rod tightly, which reduces the torque output demand of the steering gear and expands the selection range of the steering gear. It solves the problems of too large design types, difficult operation, and low reliability of conventional steering gears, mainly including chute holes, curved surface connecting rods, connecting rod shells, force-reducing curved surfaces, elastic elements, telescopic support shafts, rollers, slide rails, in:

Abstract

A steering engine torque compensation mechanism capable of reducing control surface torque comprises a sliding groove hole, a curved surface connecting rod, a connecting rod shell, a force reducing curved surface, an elastic element, a telescopic supporting shaft, a rolling wheel and a sliding rail. Through connection with a steering engine and a control surface, the control surface torque is compensated through an acting force generated by driving a roller to be pressed on a curved surface connecting rod by utilizing an elastic element, the torque output requirement of the steering engine isreduced, the selection range of the steering engine is expanded, and the problems that a conventional steering engine is too large in design variety, difficult to operate and low in reliability are solved.

Description

technical field [0001] The invention relates to a torque compensating mechanism of a steering gear for reducing the torque of a steering surface, and belongs to the design field of steering gear mechanisms. Background technique [0002] At present, the rudder surface control of the aircraft generally adopts hydraulic or electric steering gear. Since the attitude change of the entire aircraft depends on the change of the aerodynamic force on the rudder surface, the aerodynamic force on the rudder surface is generally relatively large, so a rudder with large power and torque is required. The machine can control the rudder surface. For hydraulic steering gear, higher pressure is required; for electric steering gear, higher voltage and current are required, high hydraulic pressure, high current, and voltage are likely to cause steering gear failure, reduce the reliability of the steering system, and Steering gear is heavy. For an aircraft that is extremely weight-sensitive, ex...
