AI Technical Summary
The existing shock absorber casters have difficulties in installation and maintenance, and when applied to mobile DRs with narrow body widths, there is a lack of compression limit protection measures, resulting in an increased risk of rollover.
A shock absorbing caster structure including caster bracket, caster compression bracket and elastic support is designed. Through the connection of the rotating shaft and lock nut, a more compact structure and more convenient installation and maintenance are achieved. At the same time, a shock absorbing limit block is added between the upper end of the caster compression bracket and the bracket to protect the limit position.
A shorter installation height and a smaller rotation radius are achieved, which simplifies the installation and maintenance of springs, and effectively improves the rollover problem through extreme position protection measures.
