Embodiment Construction

[0030] refer to figure 1 and figure 2 , depicts the engine 10 comprising the motor shaft 20 and the casing 22 of the motor shaft 20 forming a protective box for the motor shaft 20 .

[0031] Throughout the following, the term "longitudinal" is defined with respect to the direction along which the engine shaft 20 extends.

[0032] In the longitudinal direction L, the engine 10 comprises a drive side E intended to be placed on one side of the device to be driven and an opposite drive side N.

[0033] Preferably, engine 10 includes an air cooling system.

[0034] Cassette 22 comprises two webs or end caps 24 , 25 substantially perpendicular to the longitudinal direction L . One of the webs 24 of the casing 22 is located on the drive side E and the other 25 of the webs is located on the opposite drive side N. FIG.

[0035] For example, at least one web 25 of the casing 22 includes a protective element 26 . In the example shown, the protective element 26 is a grid. The prote...

Abstract

The present invention relates to an engine (10) of a rail vehicle, which includes an engine shaft and a casing (22) of the engine shaft. The engine shaft extends in the longitudinal direction (L) between two ends (26, 28) and is installed in a way that can be rotated and moved around the longitudinal axis (X) relative to the casing (22), and the casing (22) includes two webs (24, 25) perpendicularto the longitudinal axis (X). The engine (10) includes at least one stop device (30) that prevents the engine shaft from moving axially relative to the casing (20). The stop device (30) includes a lock rod of the engine shaft, the lock rod extending in the longitudinal direction and is installed in a stop position along the longitudinal direction (L), preferably a reversible stop position, wherein the locking rod (L) is in direct contact with the engine shaft and prevents the generator shaft from moving axially relative to the casing.

Description

technical field [0001] The invention relates to an engine of a rail vehicle, which comprises an engine shaft and a casing of the engine shaft, and the engine shaft can rotate and move relative to the casing. Background technique [0002] Such engines are used, for example, for mounting on bogies of rail vehicles. [0003] It is known in the prior art to protect such engines subject to induced vibrations and more specifically to protect the engine shaft, for example due to the Transport of the engine between the place of manufacture of the bogie and the place of installation of the rail vehicle that receives the bogie. [0004] These induced vibrations generate, for example, a radial or axial movement of the engine shaft, causing premature operational wear of the engine shaft. [0005] Document FR 3049548 describes an engine of a rail vehicle comprising at least one contact shoe comprising a contact surface in contact with the engine shaft or with a component rotationally c...
