    • A mechanical or parking actuator for a caliper disc brake is disclosed. The actuator includes a first socket mounted coaxially on a force transmitting member disposed within the caliper housing, a second socket pivotally mounted on the caliper housing for rotation about an axis offset from the axis of the force transmitting member and the first socket, and a force transmitting element or sphere disposed in the cavity defined by the first and second sockets. A lever is provided for rotating the second socket about the offset axis from a normal or neutral position wherein the second socket is aligned with the first socket and the force transmitting member to an applied position wherein the second socket is moved eccentric to the first socket, to thereby urge the force transmitting element to roll up the sides of the sockets, to thereby generate a force tending to separate the sockets. This separating force urges the force transmitting member, which is operably connected to the friction elements of the brake, in a direction which urges the friction element into frictional engagement with the brake rotor.
    • 公开了一种用于卡钳盘式制动器的机械或驻车致动器。 所述致动器包括同轴地设置在设置在所述卡钳壳体内的力传递部件上的第一插座,枢转地安装在所述卡钳壳体上的第二插座,用于围绕所述力传递部件和所述第一插座的轴线偏移的轴线旋转, 设置在由第一和第二插座限定的空腔中的传输元件或球体。 提供了一个杠杆,用于使第二插座绕着偏移轴线从正常或中立位置旋转,其中第二插座与第一插座和力传递构件对准到施加的位置,其中第二插座偏移到第一插座, 从而促使力传递元件卷起插座的侧面,从而产生趋向于分离插座的力。 这种分离力促使力传递构件可操作地连接到制动器的摩擦元件,该方向促使摩擦元件与制动转子摩擦接合。

    • A disc brake is disclosed which includes both a hydraulic service actuator and a mechanical parking or emergency actuator. The brake includes a caliper which defines a stepped bore therewithin, and a pair of coaxial members mounted, along with the hydraulic piston, in the larger diameter portion of the bore. A pin extends transversely across the bore through both of the members. One of the members is provided with a longitudinal slot which receives the pin, locking the one member against rotation relative to the bore, but permitting relative axial movement therebetween. The other member is provided with an arcuate slot, preventing the latter from moving axially, but permitting rotation of the other member through a predetermined arc. The other member is stepped to define a shoulder thereon which faces the shoulder provided on the bore. Camming means are disposed between the members, so that, when the other member is rotated, the one member is urged into engagement with the piston and thereafter the one member and the piston are urged as a unit in a brake-applying direction, the forces generated by the brake application being transmitted through the members to the shoulder on the housing.
    • 公开了一种盘式制动器,其包括液压操作致动器和机械停车或紧急执行器。 该制动器包括在其中限定了阶梯孔的卡钳以及与液压活塞一起安装在孔的较大直径部分中的一对同轴件。 销通过两个构件横向穿过孔延伸。 其中一个构件设置有纵向狭槽,其容纳销,锁定一个构件相对于孔抵抗旋转,但允许它们之间的相对轴向移动。 另一个构件设置有弓形狭槽,防止后者轴向移动,但允许另一个构件旋转预定的弧。 另一个构件被阶梯形地限定其上面设置在孔上的肩部的肩部。 凸轮装置设置在构件之间,使得当另一构件旋转时,一个构件被推动与活塞接合,此后一个构件和活塞作为制动施加方向的一个单元被推动,力 由制动器应用产生的通过构件传递到壳体上的肩部。
