Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A large-torque large-steering mechanism is shown in figures 1 to 3 and comprises an upper rocker arm 14 and a lower rocker arm 7 which are arranged at the upper end and the lower end of the side surface of a frame 4, a goat's horn frame 8 is arranged between the upper rocker arm 14 and the lower rocker arm 7, a steering wheel 1 is arranged at the front end of the goat's horn frame 8, a steering support 9 is arranged on the side surface of the goat's horn frame 8, a steering pull rod group is arranged at the end part of the steering support 9, and the steering pull rod group is connected with an electric push rod 11; the bottom surface of the frame 4 is provided with a motor screw 13, the moving end of the motor screw 13 is provided with a push rod mounting seat 12, and the electric push rod 11 is mounted on the push rod mounting seat 12.
The upper rocker 14 is mounted to the upper rocker mounting bracket 5 and the lower rocker 7 is mounted to the lower rocker mounting bracket 6.
The upper end of the frame 4 is also provided with a shock absorber mounting frame 2, a shock absorber 3 is arranged below the shock absorber mounting frame 2, and the lower end of the shock absorber 3 is arranged above the lower rocker arm 7.
The steering pull rod group comprises two pull rods 10, and a double-threaded screw 15 is arranged between the two pull rods 10.
A straight dustproof sleeve 16 is arranged below the motor screw rod 13.
The utility model discloses a have 150 mm's small-size light weight, 48V low-voltage, 50W's miniwatt, 30 decibels low noise, 1400N high thrust IP65 level waterproof electric putter.
A large-torque large-steering method drives a steering pull rod group to act by moving a motor screw rod and/or an electric push rod, so that a claw frame is driven to rotate around an upper rocker arm and a lower rocker arm, and finally steering adjustment of a steering wheel is realized.
In the initial state, the push rod mounting seat on the motor screw rod is positioned at the innermost end and does not participate in the adjustment of the steering angle of the steering wheel. When the steering wheel is in small steering, the steering of the steering wheel is realized only by the stretching of the electric push rod.
The specific process for realizing large steering is as follows: firstly, the output end of an electric push rod starts to extend to drive a steering wheel to steer, after the output end of the electric push rod reaches the maximum extension position of the electric push rod, a motor screw rod starts to move outwards to drive a main body of the electric push rod to move outwards, meanwhile, the output end of the electric push rod starts to contract synchronously, and the contraction speed of the output end of the electric push rod is the same as the outward movement speed of the motor screw rod; when the motor screw rod stops acting after reaching the designated position, the output end of the electric push rod continues to extend to drive the steering wheel to continue steering until reaching the maximum extension position of the electric push rod, and large-angle steering of the steering wheel is realized.
