前言近代,由于汽車行駛速度的提高,其所采用的高功率的盘形制动装置获得了好評。铁道車辆的高速运行,十年来也导致了盘形制动装置的发展。根据动能公式(1/2mv~2),当制动力保持不变时,制动距离随速度的平方而增加。但在铁路运营中,远距离信号与基本信号的距离限制了制动距离,因而在一定程度上也限制了运行速度。如欲提高运行速度,則須增加远距离信号与基本信号的距离,或加大制动力。和近郊快車相同,在长途交通中,加大制动力的問題,也曾一再向設計师們提出。为了提高压縮空气摩擦制动装置的制动力,应考虑一系列构造上的可能性:閘瓦块分段的閘瓦或双閘瓦块組成一閘瓦,以
Introduction In modern times, due to the increase of car speed, the high-power disc brake device adopted by it gained good comments. The high-speed operation of railway vehicles has also led to the development of disc brake units over the past decade. According to kinetic energy formula (1 / 2mv ~ 2), when the braking force remains unchanged, the braking distance increases with the square of the speed. However, in the railway operation, the distance between the long-distance signal and the basic signal limits the braking distance, which limits the running speed to a certain extent. If you want to increase the running speed, you must increase the distance between the long distance signal and the basic signal or increase the braking force. And the suburbs express the same, in the long-distance traffic, increasing the issue of braking force, but also has repeatedly made to the designers. In order to increase the braking force of the friction brake of the compressed air, a number of structural possibilities should be considered: the brake shoes or brake shoes,
