ПРИМЕНЕНИЕ АГРЕГАТНЫХ ТЯГОВЫХ ПРИВОДОВ ДЛЯ ЛОКОМОТИВОВ С ПОВЫШЕННЫМИ ТЯГОВЫМИ СВОЙСТВАМИ

Abstract

In order to implement the increased traction power of locomotives, rational solutions of traction drives with an aggregate layout are considered as a more technologically advanced alternative to integrated traction drives of foreign companies. As a result of the know-why analysis, the following was established: the use of an integrated circuit is induced by the objective of developing a drive for locomotives with different track gauge; the transition to an aggregate layout requires an increase in the axial dimension of a traction drive, the creation of an elastic-compensating coupling, operable at a rotational speed of up to 4000 min-1, and an increase in the number of bearings in the drive. It is grounded that it is possible to increase the dimensions of the locomotive’s 1520 mm gauge drive to equip it with a coupling joint of a maximum diameter of 570 mm and an axial dimension of 200 mm, as well as the technical possibility of creating a workable elastic-compensating coupling joint with rubber elastic elements in these dimensions according to the conditions of adhesion of rubber with metal. The structural layouts of an aggregate traction drive are proposed, allowing to reduce the number of bearings in it, as well as an aggregate traction drive with elastic support on the axle, which makes it possible to use such a drive for passenger locomotives with the wheels of 1220-1250 mm diameter.
