鲁卡斯·格林公司新研制一种带有直接气动机构的重型载重汽车用盘式制动器。其特点是:带自动调节的全封气动系统,摩擦块更换简便。制动器的活动卡钳有直径为396毫米的通风盘。这种盘式制动器运用于轴荷13吨的汽车。机械式气动结构由两个并排装在一起的螺旋凸轮组件组成,以使得对卡钳轴向压力保持平衡,保证摩擦接触均匀并防止摩擦片磨损。每个环形件都有一个活动斜道,活动斜道夹在固定斜道和止推环之间,这三个零件用滚针座圈隔开。
Lucas Green has newly developed a disc brake for heavy duty trucks with a direct pneumatic mechanism. Its features are: with automatic adjustment of the whole seal pneumatic system, friction block replacement is simple. The brake caliper has a vent disk 396 mm in diameter. This disc brake applied to the axle load 13 tons of cars. The mechanical pneumatic structure consists of two helical cam assemblies assembled together side-by-side to allow for balanced axial pressure on the caliper, to ensure uniform frictional contact and to prevent wear of the friction plate. Each ring has a moving ramp, moving ramp sandwiched between the fixed ramp and the thrust ring, these three parts separated by needle race.
