AI Technical Summary

Technical Problem

When the drive wheels slip, the load changes, or the ground friction changes, the existing vehicle deviates from the preset trajectory and the error accumulates, resulting in a decrease in accuracy. The electronic closed-loop control system is costly, complex in structure, and has poor environmental adaptability.

Method used

The cam-type tracking steering trolley is composed of a pure mechanical closed-loop system consisting of a drive unit, sensing components, differential device, and correction components. The mileage cam and feedback push rod sense the actual motion, the differential device compares the theoretical and actual values, the threaded shaft and gear combination transmits the error signal, the planetary carrier synthesizes the correction value, and the main cam and rocker arm assembly adjust the steering.

Benefits of technology

It enables real-time sensing and autonomous compensation of path deviations without electronic components, adapting to complex environments and improving the accuracy and repeatability of the vehicle under harsh working conditions.

Abstract

A cam-type tracking steering vehicle and a vehicle correction method are disclosed. The vehicle includes a seat, a drive unit, an execution module, and a feedback compensation module. The feedback compensation module includes a sensing component and a differential device. The differential device has a first signal input terminal connected to the output of the drive unit and a second signal input terminal connected to the sensing component. The signal output terminal of the differential device is connected to a correction component, which is drivenly connected to the execution module. This enables the execution module to dynamically adjust the steering timing. At the same time, the real-time perception and autonomous compensation process of the vehicle path does not involve electronic components, which can adapt to complex working environments and expand the applicable scenarios of the vehicle.
