[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figure 1-Figure 3As shown, an electric forklift driving brake and steering structure in this embodiment includes a body 1, a frame 2 is fixed to the lower middle part of the body 1, auxiliary wheels 3 are installed at both ends of the frame 2, and the auxiliary wheel 3 is covered with a rubber wheel 4, an electric shaft 5 is provided on the side of the frame 2 close to the auxiliary wheel 3, a spring 6 is covered on the electric shaft 5, and a brake pad 7 is installed on the side of the electric shaft 5 away from the auxiliary wheel 3, connecting rod 1 9 is installed at the four corners of the body 1, a connecting rod 2 10 is installed between the two connecting rods 1 9 installed on the front side of the body 1, a telescopic rod 11 is installed at one corner of the body 1, a wheel 12 is installed on the outside of the connecting rod 1 9, and the outside of the wheel 12 is covered with a rubber wheel 2 8, and the telescopic rod 11 controls the steering of the wheel 12.

[0031] like Figure 1-Figure 3 As shown, in this embodiment, the frame 2 is bolted to the vehicle body 1, the auxiliary wheel 3 is rotatably connected to the frame 2, and the auxiliary wheel 3 can prevent the device from rolling over. The electric shaft 5 is rotatably connected to the frame 2, and the brake pad 7 is fixedly connected to the electric shaft 5. The electric shaft 5 rotates upon receiving a signal, and the brake pad 7 contacts the auxiliary wheel 3, and the auxiliary wheel 3 stops. The connecting rod 1 9 is rotatably connected to the vehicle body 1, the connecting rod 2 10 is rotatably connected to the connecting rod 1 9, and the wheel 12 is rotatably connected to the vehicle body 1, so that the connecting rod 2 10 can control the rotation of the wheel 12. The fixed portion of the telescopic rod 11 is rotatably connected to the vehicle body 1, and the telescopic portion of the telescopic rod 11 is connected to the connecting rod 1 9. The connection at the connection point of the connecting rod 2 10 is rotated, so that the telescopic rod 11 can control the movement of the connecting rod 2 10. A transmission hydraulic box 13 is fixed on the vehicle body 1, and a steering wheel 14 is installed on the transmission hydraulic box 13. A hose 15 is connected between the transmission hydraulic box 13 and the telescopic rod 11. There is hydraulic oil in the transmission hydraulic box 13, the hose 15 and the telescopic rod 11.

When braking, the electric shaft 5 receives a signal to rotate, driving the brake pads 7 to contact the side walls of the auxiliary wheels 3, and the auxiliary wheels 3 stop rotating, thereby increasing the friction between the electric forklift and the ground during braking and shortening the braking time. When the electric forklift is rotating, the driver turns the steering wheel 14, and the hydraulic oil in the transmission hydraulic box 13 will enter and exit the telescopic rod 11 through the hose 15, controlling the extension and contraction of the telescopic rod 11. The telescopic rod 11 controls the movement of the connecting rod 2 10, and the connecting rod 2 10 controls the movement of the connecting rod 1 9. The connecting rod 1 9 drives the wheel 12 to turn, and the electric forklift turns. At this time, the auxiliary wheels 3 increase the width of the electric forklift, making it less likely to overturn when turning.
