Reliability issues of pneumatic brake actuators of vehicles
Abstract
The issues of reliability of pneumatic brake drives of vehicles nowadays become more and more important in the light of increasing requirements to braking systems in terms of decreasing the time of braking mechanisms operation, decreasing the braking distance of vehicles, increasing the maximum deceleration created by the braking system as a whole. In this case there is a very difficult task of finding reserves of braking systems, because at first glance it seems that the pneumatic braking system has already reached the limit of its development and can not be further improved, except for the use of microprocessor technology and an on-board computers, which, along with many positive properties, significantly increases the cost and complexity of the system itself, and ultimately reduces its maintainability and, as a consequence, reliability .
