Estimating the term…
The steering apparatus in which at least part of the transmission lines (L1, L3) which transmit the control quantity of steering from the steering wheel (20, 120, 220) to the rudder (30, 130, 230) is constituted from a steering cable such as wire so as to steer the rudder by transmitting the control quantity of operating the steering wheel to the rudder through reciprocal motion of the transmission line. The assisting force supplying means (70, 170, 270) is additionally installed and the intermediate linkage rod (60, 160, 260) is installed to interpose in the transmission line, with the transmission line (L2) for transmitting the assisting force supplied from the assisting force supplying means being connected to said intermediate linkage rod in addition to the transmission lines described above, so that the intermediate linkage rod is moved back and forth by the sum of the manual force from said steering wheel and the assisting force from the assisting force supplying means, thereby to steer the rudder.
A steering apparatus including a transmission line for transmitting control quantity of steering from a steering wheel (20, 120, 220) to a rudder (30, 130, 230) comprising a steering cable means, for steering the rudder by transmitting the control quantity of operating the steering wheel to the rudder by reciprocal motion of said transmission line, wherein assisting force supplying means (70, 170, 270) is additionally installed for supplementing the manual force required to operate the steering wheel and an intermediate linkage rod (60, 160, 260) is installed to interpose in said transmission line, with the transmission line (L1) from the steering wheel and the transmission line (L3) to said rudder being linked to said intermediate linkage rod and the transmission line (L2) for the assisting force supplied from said assisting force supplying means is connected thereto, so that said intermediate linkage rod is moved back and forth by the sum of the manual force from the steering wheel and the assisting force from the assisting force supplying means, and the control quantity from said steering wheel is transmitted to the rudder, thereby steering the rudder, wherein the linkage point (P1) of the transmission line (L1) from the steering wheel (20, 120, 220) to the intermediate linkage rod (60, 160, 260) and the linkage point (P2) of the transmission line (L2) from the assisting force supplying means (70, 170, 270) are located apart from each other, and control means (90, 190, 290) is provided which, when there arises a deviation from the initial state in the positional relation between these linkage points due to the operation of the steering wheel, directs said assisting force supplying means to supply assisting force in such a direction that cancels said deviation, wherein a linkage point (P3) of a transmission line (L3) from the intermediate linkage rod (60, 160, 260) to the rudder (30, 130, 230) is provided with the position, thereof being adjustable, at a midpoint between the linkage point (P1) of the transmission line (L1) from the steering wheel (20, 120, 220) to the intermediate linkage rod and the linkage point (P2) of the transmission line (L2) from the assisting force supplying means (70, 170, 270) to the intermediate linkage rod.
A steering apparatus including a transmission line for transmitting control quantity of steering from a steering wheel (20, 120, 220) to a rudder (30, 130, 230), comprising a steering cable means for steering the rudder by transmitting the control quantity of operating the steering wheel to the rudder by reciprocal motion of said transmission line, wherein assisting force supplying means (70, 170, 270) is additionally installed for supplementing the manual force required to operate the steering wheel and an intermediate linkage rod (60, 160, 260) is installed to interpose in said transmission line, with the transmission line (L1) from the steering wheel and the transmission line (L3) to said rudder being linked to said intermediate linkage rod and the transmission line (L2) for the assisting force supplied from said assisting force supplying means is connected thereto, so that said intermediate linkage rod is moved back and forth by the sum of the manual force from the steering wheel and the assisting force from the assisting force supplying means, and the control quantity from said steering wheel is transmitted to the rudder, thereby steering the rudder, wherein the linkage point (P1) of the transmission line (L1) from the steering wheel (20, 120, 220) to the intermediate linkage rod (60, 160, 260) and the linkage point (P2) of the transmission line (L2) from the assisting force supplying means (70, 170, 270) are located apart from each other, and control means (90, 190, 290) is provided which, when there arises a deviation from the initial state in the positional relation between these linkage points due to the operation of the steering wheel, directs said assisting force supplying means to supply assisting force in such a direction that cancels said deviation, wherein the assisting force supplying means (70, 170, 270) includes at least a motor (71, 171, 271), a speed reducer (72, 172, 272) and a mechanism (74, 174, 274) which transforms the rotary motion of said motor into reciprocal motion.
