The main steering wheel unit 10 includes a main steering wheel 101, a steering gear 102, and a transmission mechanism 103 arranged between the main steering wheel 101 and the steering gear 102, and the steering gear 102 may be an electrohydraulic hybrid steering gear 102. The auxiliary steering wheel unit 11 includes an auxiliary steering wheel 111, an electric control steering booster 112, and a first upper transmission shaft 113 disposed between the auxiliary steering wheel 111 and the electric control steering booster 112, and the electric control of the electric control steering booster 112 and the electric control of the steering gear 102 are electrically connected to the control unit 12 in parallel (the electric control is a chip or a processor of the electric control steering booster 112 and the steering gear 102, which is determined according to the model of the product itself, and is a common prior art, and detailed description thereof is omitted herein). Specifically, when the driver performs a steering operation on the main driver's seat, since the transmission mechanism 103 is provided between the main direction plate 101 and the steering gear 102, a force acting on the main direction plate 101 is transmitted to the steering gear 102 through the transmission mechanism 103, and the steering operation is performed by the steering gear 102. Meanwhile, when the steering device 102 performs steering operation, the electric controller on the steering device 102 transmits steering signals to the control unit 12 and transmits the steering signals to the auxiliary steering wheel unit 11, namely, after the control unit 12 receives the steering signals transmitted by the electric controller on the steering device 102, the control unit 12 transmits the steering signals to the electric controller on the electric control steering booster 112, and then the electric control steering booster 112 performs steering operation of the auxiliary steering wheel 111 so as to realize the same-direction rotation of the double steering wheels and further realize the rotation of the whole vehicle.
Further, when the steering operation is performed on the auxiliary steering wheel unit 11, the steering force on the auxiliary steering wheel 111 directly drives the electric control steering booster 112 to perform the steering operation through the first upper transmission shaft 113, meanwhile, the electric control on the electric control steering booster 112 transmits a steering signal to the control unit 12, then the control unit 12 transmits the steering signal to the electric control on the steering gear 102, and after the electric control on the steering gear 102 receives the steering signal, the steering operation is directly performed by the steering gear 102; at this time, the main steering wheel 101 does not perform a turning operation, and the steering operation by the sub steering wheel 111 is performed.

As shown in fig. 1 and 2, a booster motor (not shown) is provided on the steering gear 102 in the present embodiment, and the booster motor is electrically connected to the control unit 12, specifically, when the steering gear 102 actively or passively performs steering operation, the booster motor provided on the steering gear 102 provides steering assistance thereto, so that the steering operation of the driver can be made lighter, and the efficiency of the whole vehicle steering can be improved.
As shown in fig. 1 and 2, the present embodiment further includes a drop arm 13 and a steering rod 14, one end of the drop arm 13 is disposed at the output end of the steering device 102, and the steering rod 14 is hinged at the other end of the drop arm 13 (the hinge mode may be a shaft hole hinge mode, so as to implement the rotation or swing action of the steering rod 14).
Specifically, the output end of the steering device 102 is connected with one end of the drop arm 13, when the steering device 102 performs steering operation, the drop arm 13 connected with the drop arm is driven to correspondingly rotate, the other end of the drop arm 13 is hinged with the steering pull rod 14, the steering pull rod 14 is further connected to the knuckle arm of the steering axle of the vehicle, and thus, the drop arm 13 and the steering pull rod 14 form a transmission structure for transmitting steering intention and steering force of the steering device 102 to the knuckle arm of the steering axle of the vehicle, and further driving the whole vehicle to steer.
As shown in fig. 1 and 2, the embodiment also comprises a steering oil pot 15 and a double-source steering pump 16, wherein an oil return port of the steering oil pot 15 is communicated with an oil outlet of the steering device 102; the oil inlet of the double-source steering pump 16 is communicated with the oil outlet of the steering oil pot 15, and the oil outlet of the double-source steering pump 16 is communicated with the oil inlet of the steering device 102.
Specifically, the dual-source steering pump 16 is configured to output hydraulic oil, and an oil outlet of the dual-source steering pump 16 is communicated with an oil inlet of the steering gear 102 to form a high-pressure oil path, so as to provide power for driving the steering gear 102 to rotate, so as to ensure efficient operation of the steering gear 102.
In addition, the oil return port of the steering oil can 15 is communicated with the oil outlet of the steering gear 102, and the oil outlet of the steering oil can 15 is also communicated with the oil inlet of the double-source steering pump 16, so that after the double-source steering pump 16 outputs hydraulic oil to the steering gear 102 to drive the steering gear 102 to operate, the oil outlet of the steering gear 102 can discharge hydraulic oil to the steering oil can 15, and then is discharged through the oil outlet of the steering oil can 15 and is conveyed back to the double-source steering pump 16. The design of the circulating oil path among the steering gear 102, the steering oil can 15 and the double-source steering pump 16 is formed, when the double-source steering pump 16 conveys hydraulic oil to the steering gear 102, a high-pressure oil path is formed, so that the steering gear 102 is driven to rotate, when the steering gear 102 needs to maintain the current state and stops rotating, the steering gear 102 discharges the hydraulic oil to the steering oil can 15 and then transmits the hydraulic oil back to the double-source steering pump 16 through the steering oil can 15, at the moment, the hydraulic oil in the steering gear 102 is reduced, and the hydraulic oil in the oil path is circulated back to the double-source steering pump 16, so that the steering gear 102 stops rotating.
