Problems solved by technology

Due to the high moments of inertia of the drive train part on the drive side of the rail vehicle and the high moments of inertia of the drive train part on the output side of the rail vehicle, the form-fitting elements of the shifting clutch can in extreme cases be lost during a shifting process that is not yet exactly synchronized have been damaged, e.g. because individual or all claws of a claw clutch have been sheared off

Embodiment Construction

[0049] figure 1 A first bogie 1 and a second bogie 51 are shown, which are arranged in the understructure of the rail vehicle. Each bogie 1, 51 has two drive trains. Each drive train comprises an electric drive machine 2, 22, 52, 72 and a shift transmission 3, 23, 53, 73 respectively, which are respectively used to drive a motor with a plurality of possible transmission ratios. Wheel axles 4, 24, 54, 74. The two electric drive machines 2 and 22 or 52 and 72 , each associated with a bogie, are powered here via a common AC converter 100 or 101 . The drive power is further transmitted by the gearshift transmission 3, 23, 53, 73 to the respectively associated wheel set axles 4, 24, 54, 74 and the track wheels 5, 6, 25, 26, 55, 56, 75 arranged thereon , 76. The two electric drive machines 2 , 22 , 52 , 72 each assigned to a bogie 1 , 51 are powered via a common AC converter 100 or 101 .

Abstract

The invention relates to a drive system of a rail vehicle comprising several drive trains, each having an electric drive engine and a transmission with at least one positively engaging shifting clutch for producing several transmission ratios. The electric drive machines are fed via a common alternating current converter. At least one drive train of the drive system comprises a partial load shift element for synchronizing an input speed of rotation with an output speed of rotation on the positively engaging shifting clutch. The invention also relates to a method for controlling a corresponding shifting operation.

Description

technical field [0001] The invention relates to a drive system and a method for controlling a shifting process in an electric motor-driven rail vehicle. Background technique [0002] Recently, it has been sought to equip drive systems of rail vehicles operated with electric motors with shift transmissions, so that several transmission ratios or gear steps can be provided. As a result, the electric drive machine always operates within a favorable efficiency range, resulting in lower energy consumption. The electric drive machine mentioned here of a rail vehicle, which provides the main power for the drive of the rail vehicle, is also referred to as a traction motor. [0003] Furthermore, electric motor-driven rail vehicles are known, in which a plurality of electric motors, each associated with one or more drive axles or wheel sets, are supplied with power via a common AC converter. In this case, a plurality of electric drive machines are then electrically coupled in parall...
