МОДЕРНІЗАЦІЯ СТРУМОПРИЙМАЛЬНОЇ ГОЛОВКИ ТРОЛЕЙБУСА

Abstract

The article deals with the issue of improving the reliability of the existing fleet of passenger trolleybuses. One of the possible options for increasing the reliability of operation of the trolleybus fleet is presented. Based on the collected statistical data, the typical causes of trolleybus failures were identified. It has been shown that the largest number of trolleybus failures is associated with electrical equipment malfunctions. It is determined that one of the most promising ways to reduce the number of failures is to improve the reliability of current collectors. To this end, the general state of affairs in this field was analyzed. A method for improving the reliability of current collector operation in adverse weather conditions is proposed. To solve this problem, it is proposed to change the design of the current collectors. The existing ways of solving this problem are investigated. The advantages and disadvantages of the existing methods are determined. The paper proposes a new constructive solution, which, according to the authors' idea, allows solving the problem. The essence of the solution is the simultaneous installation of two current-collecting inserts on the current collector rod. The current collecting inserts used have different physical properties and, when working together, improve the operating conditions of the trolleybus current collecting system. The proposed solution reduces the number of trolleybus current-collecting rod disconnections from the contact network. This leads to an increase in the stability of the trolleybus electrical system. At the same time, the operating conditions of the mechanical part of the trolleybus structure are improved. This leads to an increase in the stability of the trolleybus electrical system. At the same time, the operating conditions of the mechanical part of the trolleybus structure are improved. By reducing the number of forced braking of the trolleybus, the level of safety and comfort of passengers increases. Reducing the total number of failures of the current collector system and reducing the level of loads on the mechanical systems of the trolleybus allows to increase the overhaul mileage and reduce the level of costs in the operation of the trolleybus fleet
