Electric control steering system for auxiliary driving of agricultural machinery and agricultural machinery

Abstract

The invention relates to the technical field of electric control, and discloses an electric control steering system for auxiliary driving of agricultural machinery and the agricultural machinery. The electric control steering system comprises a steering wheel control mechanism, a switching kit, a steering wheel angle sensor, an electric control steering gear, a front axle angle sensor and an auxiliary driving controller. A direction tubular column of the steering wheel control mechanism is in meshing transmission connection with the electric control steering gear through a switching kit; the steering wheel angle sensor is arranged on a transmission shaft of the adapter sleeve in a sleeving mode and is in meshing transmission connection with the transmission shaft, the steering wheel angle sensor and the front axle angle sensor are both electrically connected with the auxiliary driving controller, and the auxiliary driving controller is electrically connected with the electric control steering gear. The whole structure is simple, all the structures are connected compactly, auxiliary driving control can be achieved without additionally arranging a steering wheel motor, and the situation that due to additionally arranging the steering wheel motor, a steering control system occupies a large space, the height of a steering wheel is increased, and the driving experience of a driver is affected is avoided.

Description

technical field [0001] The invention relates to the field of electric control technology, in particular to an electric control steering system for auxiliary driving of agricultural machinery and agricultural machinery. Background technique [0002] With the current development of navigation technology, more and more assisted driving scenarios are used in the operation of agricultural machinery (such as tractors). The existing auxiliary driving of agricultural machinery mostly uses the electric steering wheel to control the steering system. However, the electric steering wheel controls the steering system to install a steering wheel motor. The steering wheel motor needs to be fixed by the motor bracket, so the height of the steering wheel will be increased, which will affect the driver's driving experience; and The installation structure of the electric steering wheel is relatively complicated, and the connection through the bracket is prone to connection gaps, and the instal...

Problems solved by technology

The existing auxiliary driving of agricultural machinery mostly uses the electric steering wheel to control the steering system. However, the electric steering wheel controls the steering system to install a steering wheel motor. The steering wheel motor needs to be fixed by the motor bracket, so the height of the steering wheel will be increased, which will affect the driver's driving experience; and The installation structure of the electric steering wheel is relatively complicated, and the connection through the bracket is prone to connection gaps, and the installation is difficult. When controlling, the motor rotates the steering column, and the steering column drives the hydraulic steering gear to rotate. Many process connections will reduce the control accuracy of the steering angle.
