BG785Y1 - Cardan drive of tramcar vehicle - Google Patents

Abstract

The drive comprises a traction motor (1), mounted to the chassis of the tramcar by means of a step-down reductor (2), flange connection (3), low rotation long cardan shaft (4) which, by means of a second flange connection (5) drives a step-up reductor (6) mounted to the wheel pair reductor (7), fitted on the wheel pair (8). By the built-in reductor (2), the frequency of revolving the cardan shaft is reduced and the dangerous dynamic loading is being reduced. The step-up reductor (6) fitted after the cardan shaft (4) ensures the required speed of the tramcar.

Description

Technical field

The utility model relates to the propulsion of a tram train and in particular a tram drive.

BACKGROUND OF THE INVENTION

It is known from BG 41872 for the tramline drive, whereby the traction motor is positioned longitudinally to the driveway basket and, via a high-speed long drive shaft and two flange couplings, drives the axial gearbox.

With this PTO drive, the presence of a high-speed long PTO shaft creates high dynamic loads and causes rapid wear on the transmission elements.

The technical nature of the utility model

The utility of the utility model is to create a propeller drive for a tram track with a slowly rotating drive shaft that has reduced dynamic loads and is safe to operate.

The problem is solved by a cardan drive for a tram track, including a traction motor located longitudinally under the basket of the track, a long drive shaft pivotally connected to two flange joints. Through the second flange connection, the shaft is connected to a axial gearbox mounted on the axle. A reduction gear is attached to the motor connected to the first flange connection.

In a second embodiment, the driveshaft is connected to the axle gearbox mounted on the axle by an uplink gearbox through the second flange connection.

In this way, the slow-motion PTO driveshaft is safe in operation and does not create a risk of accidents, as the dynamic moments are significantly reduced.
