采用带式机构的推土机制动器,由于带式机构操纵路径较长,使用过程中出现的故障率较高。采用液压助力方式的推土机制动器,则容易因液压油路出现问题而失效。而我公司产推土机广泛采用离合器式碟簧制动器,以制动离合器取代传统的带式机构,同时以碟簧取代液压助力系统,有效克服了带式机构与液压助力方式制动器的缺点。该种制动器由主动轮毂1、传动内摩擦片2、传动外摩擦片3、从动毂4、离合器压紧盘5、制动内摩擦片6、制动外摩擦片7、制动器壳体8、制动压紧盘9、碟簧10和输出轴11等组成,如附图所示。制动器壳体8与推土机机体固定连接,从动毂4
Bulldozer brakes with a belt mechanism, due to the long path of the belt mechanism, there is a higher failure rate during use. Bulldozers brakes with hydraulic boosters are prone to failure due to hydraulic fluid problems. And my company bulldozers widely used clutch disc spring brake to brake the clutch to replace the traditional belt mechanism, at the same time to replace the hydraulic servo booster system, effectively overcome the shortcomings of the belt mechanism and the hydraulic booster brake. The brake includes a driving hub 1, a driving inner friction plate 2, a transmission outer friction plate 3, a driven hub 4, a clutch pressure plate 5, a brake inner friction plate 6, a brake outer friction plate 7, a brake housing 8, Brake pressure plate 9, disc spring 10 and the output shaft 11 and other components, as shown in the figure. The brake housing 8 is fixedly connected with the bulldozer body, and the driven hub 4
