Problems solved by technology

However, the existing steering actuators mostly use mechanical structures such as steering wheels, universal joints, and worm gears to realize steering, which cannot realize automatic driving control.
For example, the steering accuracy cannot be controlled. When the steering is out of control, the positive direction of the wheel cannot be found, causing the wheel to deflect or reverse, and the lack of a vibration damping mechanism between the motor and the steering wheel causes the feedback from the ground to the wheel to be directly transmitted to the motor, reducing Motor service life

Abstract

The embodiment of the invention relates to a steering executing mechanism which comprises a hub motor assembly, an encoder, a steering transmission structure and a torque output unit, wherein the hub motor assembly is connected with a wheel; the encoder and the hub motor assembly are coaxially arranged; the steering transmission structure is arranged above the hub motor assembly and comprises a driving wheel assembly and a driven wheel assembly; the bottom surface of the driven wheel assembly is fixedly connected with the top surface of the hub motor assembly; the driving wheel assembly is matched with the driven wheel assembly for transmission; and the torque output unit is connected with the driving wheel assembly. According to the steering executing mechanism, control over the steering precision of an automatic driving vehicle can be achieved.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a steering actuator and a mobile tool. Background technique [0002] Autonomous driving is a hot field in recent years, and the development of autonomous driving technology in environmental sanitation is particularly rapid, and more and more autonomous vehicles are being tested on the road. However, most of the existing steering actuators use mechanical structures such as steering wheels, universal joints, and worm gears to realize steering, which cannot realize automatic driving control. For example, the steering accuracy cannot be controlled. When the steering is out of control, the positive direction of the wheel cannot be found, causing the wheel to deflect or reverse, and the lack of a vibration damping mechanism between the motor and the steering wheel causes the feedback from the ground to the wheel to be directly transmitted to the motor, reducing Motor life. ...
