Description

technical field [0001] The present application relates to a two-wheel steering drive wheel, which belongs to a two-wheel steering drive wheel. Background technique [0002] Defects of the existing steering drive wheel: the steering drive wheel travel drive motor and the travel drive motor coder and the travel drive motor brake rotate with the steering drive wheel, the wires and cables of the motor cannot be fixed reliably, the wires and cables will be dragged and worn, and the wires and cables will be damaged due to dragging. Electrical faults caused by wear and tear; the steering drive wheel can only turn at a limited angle in the horizontal plane, the range of rotation angle is small, and the scope of use is limited; the travel drive motor of the steering drive wheel, the encoder of the travel drive motor and the brake of the travel drive motor follow the steering The driving wheel turns and rotates, the turning radius of the steering driving wheel is large, and the size o...

Problems solved by technology

[0005] The primary purpose of this application is to solve the existing technical problems: the steering drive wheel travel drive motor and the travel drive motor encoder and the travel drive motor brake rotate with the steering drive wheel, the wires and cables of the motor cannot be fixed reliably, the wires and cables will be involved in wear, the wires Electrical faults caused by cable wear and tear; the steering drive wheel can only turn at a limited angle in the horizontal plane, the range of rotation angle is small, and the scope of use is limited; the steering drive wheel travel drive motor and travel drive motor encoder and travel drive motor The brake rotates with the steering driving wheel. The steering driving wheel has a large turning radius and the size of the vehicle is large. When the steering driving wheel turns and rolls, the friction of the rubber wheel on the ground is mainly twisted sliding friction, which is obvious to the ground and the rubber wheel. Destructive effect; the friction of the rubber wheel on the ground is mainly manifested as torsional sliding friction, the steering resistance is large, and the power consumption of the steering drive motor is high; when the load is large, the steering drive wheel is made wider, so that the rubber wheel cannot effectively contact the ground, making the rubber wheel The force on the wheel is uneven, which cannot be applied to the road with poor road conditions, and cannot effectively protect the rubber wheel; most of the exposed rotating joints of the steering drive wheel currently do not use a rotary sealing device, which makes maintenance difficult and requires frequent and regular inspections. Maintenance; the current steering drive wheel adopts a patchwork design without an overall design, and it is difficult to disassemble and maintain all parts, which is not convenient for maintenance and the maintenance cycle is short; the existing steering drive wheel is not equipped with a neutral clutch device, so it cannot be towed to Designated address maintenance; currently existing steering drive wheels are not suitable for applications with heavy loads, harsh road conditions, and harsh environments
