    • A brake cylinder for pneumatically actuated vehicle brakes, especially for commercial vehicles, includes a housing. The housing is divided into two chambers by a piston, one of the chambers being used as a pressure chamber for actuating an operating brake section, and a cylinder spring of a spring-loaded brake section being arranged in the other chamber on the opposite side of the piston. The cylinder spring acts on another spring-loaded piston in the chamber, which can be blocked in relation to the first piston by a pneumatically actuated locking mechanism. The other spring-loaded piston is released from the first piston by a releasing action of the blocking mechanism, and is connected to a piston rod for actuating the vehicle brake. Following release of the blocking mechanism, the cylinder spring acts between the two pistons and moves them in relation to each other during a parking braking operation. The brake cylinder includes a manually actuatable release device, in addition to the pneumatically actuable blocking mechanism, for manually releasing the spring-loaded brake section without impairing the function of the operating brake section.
    • 用于气动车辆制动器的制动缸,特别是用于商用车辆的制动缸包括壳体。 壳体通过活塞被分成两个室,其中一个室被用作用于致动操作的制动部分的压力室,并且弹簧加载的制动部分的气缸弹簧被布置在另一个腔室的相对侧上 活塞。 气缸弹簧作用在腔室中的另一弹簧加载的活塞上,其可以通过气动致动的锁定机构相对于第一活塞而被阻塞。 另一个弹簧加载的活塞通过阻塞机构的释放动作从第一活塞释放,并连接到用于致动车辆制动器的活塞杆。 在释放阻塞机构之后,气缸弹簧作用在两个活塞之间并且在驻车制动操作期间相对于彼此移动。 除了气动致动的阻塞机构之外,制动液压缸还包括一个可手动致动的释放装置,用于手动释放弹簧加载的制动部分而不损害操作制动部分的功能。
