二、空气制动车轮的制动,按制动力产生的方式分为两大类,即①超压制动:制动力由制动缸中的压缩空气的作用产生;②负压制动:制动力由制动缸中的负压空气的作用产生。 1. 压缩空气制动 1.1 直通式空气制动这类制动装置的制动缸是单室风缸,即压缩空气只作用在一个工作室中;而活塞的另一侧由弹簧力支撑住。在这种系统中,全部制动缸都连到一根制动风管上。制动时,压缩空气由主风缸经过司机制功阀向主风管内充气,缓解时重新排气。这种制动称为直接作用的单室制动。它只
Second, the brake of the air brake wheel, according to the way braking force is divided into two categories, namely ① overpressure brake: braking force generated by the brake cylinder in the role of compressed air; ② negative pressure brake: braking force Produced by the negative pressure air in the brake cylinder. 1. Compressed air brake 1.1 Straight air brake The brake cylinder brake is a single-chamber cylinder, that is, compressed air only in one studio; and the other side of the piston supported by spring force. In this system, all brake cylinders are connected to a brake air duct. Braking, the compressed air from the main cylinder through the driver system valve to the main air duct inflated to ease re-exhaust. This type of braking is called direct acting single-chamber braking. It only
