Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

As shown in fig. 1-6, in the present embodiment, an offset dual-rod diagonal steering is provided, which is installed at the front part of a vehicle body, and mainly comprises a driving shaft 1, a steering link 2 and an axle rod 4, wherein two ends of the axle rod 4 are used for installing tires 11, a steering sleeve frame 13 is installed at the front part of the vehicle body, the steering link 2 directly passes through the steering sleeve frame 13, and the steering link 2 is generally connected with an external vehicle head or a steering wheel. The middle part of the axle rod 4 is welded with a longitudinal central rotating shaft 5, the central rotating shaft 5 is rotatably arranged at the front end of the underframe 10 of the vehicle body, a supporting rod is generally rotatably arranged on the central rotating shaft 5, and then a vehicle basket is assembled, and the vehicle basket can be fixed by connecting a steering sleeve frame 13, so that the vehicle body can be kept stable when the vehicle is steered. The driving rotating shaft 1 is rotatably installed on the underframe 10 and located right behind the central rotating shaft 5, the universal joint 3 is fixedly installed at the top end of the driving rotating shaft 1, and the bottom end of the steering connecting rod 2 is fixedly connected to the universal joint 3. Swing arms 6 are symmetrically welded on two sides of the driving rotating shaft 1, one end, far away from the driving rotating shaft 1, of each swing arm 6 is connected with a pull rod 7 in a rotating mode, one end, far away from the swing arms 6, of each pull rod 7 is connected with a transmission clamping seat 8 in a rotating mode, and the two transmission clamping seats 8 are installed on the wheel shaft rod 4 and are symmetrical about the central rotating shaft 5.

When an external vehicle head or a steering wheel is controlled to steer, the steering connecting rod 2 rotates to drive the driving rotating shaft 1 to rotate through the universal joint 3, and the vehicle head or the steering wheel can be kept on the same plane when rotating due to the existence of the universal joint 3, so that the steering angle can be controlled visually, and the operation is comfortable and labor-saving. The driving rotating shaft 1 rotates to drive the swing arms 6 on the two sides to rotate, then the two pull rods 7 are driven to form parallel dislocation between the swing arms 6 and the transmission clamping seat 8, and the two pull rods 7 push and pull to drive the wheel shaft rod 4 to complete steering. Two pull rods 7, two swing arms 6 and axostylus axostyle 4 can keep the coplanar as far as possible when turning to, also can keep steadily well when touchhing the highway section of jolting, are difficult to take place the swing, and the use of universal joint 3, control angle is more accurate during the operation, is difficult for turning over the head.
