1.故障现象我公司最新研制了1种高驱动电子控制静液压传动履带式推土机,在对样机电子控制系统、液压系统调试后进行推土试验过程中,发现该推土机制动动作迟缓、时有时无,明显感觉制动力不足。2.制动器结构及工作原理(1)结构该型推土机有2个行走马达,通过两侧的终传动减速器,驱动两侧履带行走,制动器安装在行走马达与终传动减速器之间。该制动器为常闭式制动器,其主要由花键套2、活塞4、壳体5、蝶形弹簧6、压板7、齿圈8、静摩擦片9、
1. Symptom My company recently developed a high-powered electronically controlled hydrostatic transmission track-type tractor bulldozers in the prototype electronic control system, hydraulic system debugging after the trial found that the bulldozers braking slow, sometimes sometimes No, clearly lack of braking power. 2. Brake structure and working principle (1) Structure This type of bulldozer has 2 traveling motors, which drive the crawler on both sides to walk through the final drive reducer on both sides, and the brake is installed between the traveling motor and the final drive reducer. The brake is a normally closed brake, which is mainly composed of a spline sleeve 2, a piston 4, a housing 5, a butterfly spring 6, a pressure plate 7, a ring gear 8, a static friction plate 9,
