Problems solved by technology

If the lubricant enters the opening in the direction of rotation of the rotating component too much, the lubricant supply is not thereby increased, because the tooth space can only be filled once with lubricant, but due to the intrusion of the teeth into the opening undesired miscellaneous losses in the lubricant in the

Embodiment Construction

[0022] figure 1 A schematic vehicle diagram of a motor vehicle 2 is shown with a drive motor 4 , a transmission 6 and a clutch 8 arranged between the drive motor 4 and the transmission 6 . The transmission 6 is connected to the two rear wheels 14 via a drive shaft 10 and a differential 12 . A central axis 16 extends through the transmission 6 , the central axis 16 extending in a direction of travel 18 of the motor vehicle 2 .

[0023] figure 2 Shown is a lubricant guide hood 22 arranged within the transmission 6 (not shown here), wherein the direction to the rotating components not shown here to be accommodated in the lubricant guide hood 22 is shown and a surface area 26 pointing in the direction of the surrounding transmission housing, also not shown here. The surface region 24 pointing in the direction of the rotating component is divided into a plurality of sections 28 , 30 , 32 , 34 , 36 , 38 , 40 . The recesses in the sections 28 to 40 have different diameters and a...

Abstract

The invention relates to a lubricant guiding device and a transmission device having the same.The lubricant guiding cover (22) includes a surface area (24) constructing at least one segment (28,30,32,34,36,38,40), a transmission device arranged in at least one segment, an outer meshing part (76) of the transmission device (6) in at least one segment and a rotary member (74). A groove (72) in the segment for containing the member (74) has an opening allowing the lubricant to pass through.The outer meshing part reliance on the rotary member (74) is used for constucting the shape and the size of the opening (66).

Description

technical field [0001] The invention relates to a lubricant guide boot according to the preamble of claim 1 and to a transmission with a corresponding lubricant guide boot. Background technique [0002] Various types of lubricant guide boots are known from the prior art. Guide caps of this type are used to store lubricant at points where lubricant from the lubricant sump itself cannot or should be provided. Lubricant and coolant are thereby provided at critical points without having to suffer avoidable losses due to excessive submersion of rotating components and contamination in the lubricant sump. Especially considering oil as a lubricant. The supply of rotating components is of particular interest at those points where adequate lubrication and cooling are very important. In the case of intermeshing gearwheels of a transmission stage, this is, for example, the region of the tooth engagement. When parts of the gearwheels involved in the transmission stage sink into the ...
