Accompanying drawing explanation
Fig. 1 is left view of the present invention.
Fig. 2 is right elevation of the present invention.
In figure: 1-vehicle frame; 2-first steeraxle; 3-second steeraxle; 4-deflector; 5-angular transducer; 6-actr; 7-ECU (Electrical Control Unit); Swing arm in the middle of 8-; 9-first pull bar; 10-second pull bar; 11-first left steering joint arm; 12-first right steering joint arm; 13-second left steering joint arm; 14-second right steering joint arm.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-2, the dual rotation of a kind of dual rotation joint arm drives propons, comprise vehicle frame 1, first steeraxle 2, second steeraxle 3 and double power steering device, described second steeraxle 3 is arranged on the rear of the first steeraxle 2, first steeraxle 2 comprises the first left steering joint arm 11 and the first right steering joint arm 12, first left steering joint arm 11 and the first right steering joint arm 12 are arranged on the wheel limit, the left and right sides of the first steeraxle 2 respectively, second steeraxle 3 comprises the second left steering joint arm 13 and the second right steering joint arm 14, second left steering joint arm 13 and the second right steering joint arm 14 are arranged on the wheel limit, the left and right sides of the first steeraxle 3 respectively, described first left steering joint arm 11 is all connected with double power steering device with the first right steering joint arm 12, described dual powerplant comprises power steer and steering actuation cylinder, power steer connects the first left steering joint arm 11, steering actuation cylinder connects the first right steering joint arm 12,
