Embodiment Construction
[0074] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0075] The present invention is a wheel-drive electric car steering system, the structure is as follows: figure 1 As shown, it consists of three parts, the steering wheel assembly, the ECU unit and the steering execution assembly connected in sequence, wherein the specific structure of the steering wheel assembly is: including the steering wheel 1, the hub 2 of the steering wheel 1 is provided with splines, The hub 2 is embedded and fixed with a spline of the same specification as the one end of the steering shaft 3 through a spline. The rotation of the steering wheel 1 synchronously drives the steering shaft 3 to rotate at the same angle. The steering wheel angle sensor 5 is fixed on the steering shaft 3. The connector 4 is fixed on the steering shaft 3, and the bottom of the steering shaft 3 is also provided with a road sensor motor 6. The ...
