Detailed Description

The invention will now be further described by way of non-limiting examples with reference to the accompanying drawings:

as shown in the drawing, the electric steering wheel comprises a steering wheel 3, and a motor driving unit MDU6 is connected to the lower part of the steering wheel 3. The motor driving unit MDU6 comprises a motor 63, a driving gear 62 mounted on a motor shaft of the motor 63, a driven gear 61 meshed with the driving gear 62, and a motor controller MCU64 connected with the motor 63, wherein an inner spline housing 9 is arranged in a shaft hole of the driven gear 61, and the inner spline housing 9 is in interference fit with the driven gear 61. The upper end of the inner spline sleeve 9 is fixedly connected with the steering wheel adapter plate 5 through the inner hexagonal cylindrical head bolt 5, and the steering wheel 3 is fixedly connected with the steering wheel adapter plate 5 through the steering wheel pressing plate 2. The driving gear 62 is connected to a motor shaft of the motor 63 through an electromagnetic clutch 65. The motor controller MCU64 is used to receive signals from the position sensor of the front axle and control the forward and reverse rotation of the motor 63, which is the prior art. And a rotation stopping mechanism is also arranged to be connected with the motor driving unit MDU6 and is used for preventing the motor driving unit MDU6 from rotating, so that the control accuracy of the motor steering angle is ensured. In this embodiment, the mechanism of splining is including splining the seat 7, splining the staple bolt, it has the member to splining the lower part of seat 7, the staple bolt of splining is including splining staple bolt pole 12 and splining hoop piece 10, and the staple bolt pole 12 head of splining and splining hoop piece 10 of splining is connected through hexagon socket head cap screw 13 and can be formed the staple bolt structure, the member that splining the seat 7 with the splining staple bolt pole 12 of splining the staple bolt is connected, the upper end that splining the seat 7 with the casing of motor drive unit MDU6 passes through cross pan head screw 8 and connects. When the steering mechanism is used, the hoop end of the rotation stopping hoop is connected with the steering column 14.

In order to facilitate installation and adjustment, in this embodiment, a strip-shaped hole is formed in the rotation stopping hoop rod 12 of the rotation stopping hoop, a rubber ring 11 is arranged in the strip-shaped hole, and a rod piece of the rotation stopping seat 7 is inserted into the rubber ring 11 in the strip-shaped hole.

The utility model discloses the during operation, internal spline housing 9 is connected with direction axle spline fit. In order to realize automatic steering, the motor controller MCU64 obtains the command from the vehicle control unit VCU to steer left or right, at which time the motor 63 is started, and the driving gear 62 and the driven gear 61 connected to the motor shaft of the motor 63 rotate to drive the steering shaft to steer. When receiving the signal of the position sensor of the front axle, the rotation is stopped. When the steering is finished, the VCU of the vehicle controller sends a signal to the MCU64, the motor controller rotates reversely, the steering wheel returns, or other steering operations are executed. The MDU motor is limited to rotate through the rotation stopping hoop, and the control of the motor steering angle is guaranteed.

When the steering operation is performed manually, the electromagnetic clutch 65 is automatically turned off, thereby ensuring that the steering is not laborious as in the conventional mechanical type.

The integrated automatic steering device has the advantages of simple structure, convenience in operation and low cost, the 4G function can be expanded, and the remote control is realized by networking with remote operation and maintenance management.

Other parts in this embodiment are the prior art, and are not described herein again.
