Embodiment Construction

[0030] In these figures, the invention is described by way of example by means of an electric drive with a primary spur gear in the transmission housing 1 that rides on the axle.

[0031] as by figure 1 As is clear, an eg electrically driven drive motor 2 is fastened to the bogie frame 3 of the rail vehicle and is connected via a clutch 4 to a drive shaft 5 mounted in the transmission housing 1 of the axle transmission. Likewise arranged in the transmission housing 1 is a wheel shaft 6 mounted axially parallel to the drive shaft 5 , which is coupled to the drive shaft 5 via a spur gear stage. The wheel axle 6 serves to drive the wheels 7 of the rail vehicle. The transmission housing 1 is supported via a torque arm 19 on the bogie frame 3 of the rail vehicle.

[0032] as by figure 2 As obtained, the spur gear stage comprises a first smaller gear 17 and a second larger gear 18 . For lubricating the axle transmission, a lubricant or oil supply is provided in the transmission...

Abstract

The invention relates to a transmission housing of an axle transmission and a housing cover for the transmission housing. A transmission housing (1) for an axle transmission of a rail vehicle has at least one non-contact seal for axial sealing in the region of an axial shaft opening of the transmission housing (1), wherein , is provided with at least one housing cover (9, 9A) that seals the transmission housing (1) at least in sections on the axial side, at least a non-contact seal together with at least one for guiding the lubricant back The return channel ( 11 , 11A) into the lubricant sump ( 10 ) is integrated into the housing cover. Furthermore, the housing cover (9, 9A) of the transmission housing (1) of the axle transmission of a rail vehicle is formed in such a way that at least one non-contact contact for axially sealing the shaft bore is integrated. Type seals and at least one associated lubricant return channel (11, 11A).

Description

technical field [0001] The invention relates to a transmission housing for an axle transmission of a rail vehicle and to a housing cover for a transmission housing. Background technique [0002] A wheel set transmission for use in rail vehicles is known, for example, from publication DE 203 12 235 U1. The wheel set transmission includes a torque converter which is accommodated in a housing as a spur gear stage. An oil sump is placed on the lower part of the housing, in which lubricant is contained, into which the teeth of the spur gears sink, in order to achieve a lubricant supply in the housing. In order to prevent lubricant escaping outside the housing, non-contact seals are provided in the housing or in the lower part of the housing. In order to make it possible for the lubricant to be guided back by the seal into the lubricant groove in the interior of the housing, a return conduction line is provided in the housing. [0003] It has been found that, in order to ensure...
