AI Technical Summary

Technical Problem

The existing dry drive axle brake calipers of loaders have simple protective structures that cannot effectively prevent the accumulation of debris, especially hay, leading to a decrease in braking performance and posing a fire hazard.

Method used

A protective device is designed, comprising an arc-shaped top protective plate, outer and inner protective plates, with through holes on both sides. The inner protective plate has waist-shaped mounting holes for fixing the brake caliper assembly, enhancing the protective capability, especially preventing the accumulation of hay and isolating hay from contacting the brake disc.

Benefits of technology

It effectively prevents debris such as mud, sand, and stones from entering, while minimizing the accumulation of hay, avoiding hay ignition caused by friction and high temperature, improving protection capabilities, and ensuring braking performance and safety.

Abstract

本实用新型的一种纯电动装载机干式驱动桥制动钳防护装置，属于工程机械防护配件技术领域。包括弧形结构的顶部防护板，沿着顶部防护板长度方向两侧分别固定有外侧防护板和内侧防护板，外侧防护板和内侧防护板上均设有通孔，内侧防护板上设有两个对称分布的腰型安装孔用于固定连接制动钳总成。顶部、两侧均有护板既可以防止驱动桥上方泥沙、石子等杂物进入制动器，同时两侧护板又可以有效阻止杂物侵入，增大防护区域，提高防护能力。特别的对于草类料堆工况，两侧护板可以最大限度减少制动盘处草料堆积，最重要的是可以有效隔离草料与制动盘的接触，从而避免摩擦高温引起的草料点燃现象，起到阻燃防火作用。
