Problems solved by technology

[0003] This can lead to oil foaming and increased splash losses
In addition, there is a risk of transmission oil being picked up by the shock absorber escaping from the transmission exhaust
In the event of oil foam formation, the oil level in the transmission rises further, which in turn can lead to an increase in the drag torque of the shock absorber

Embodiment Construction

[0044] Various embodiments are now described in greater detail and with reference to the accompanying drawings in which several embodiments are shown.

[0045] Although the embodiments may be modified and changed in various ways, the embodiments are shown in the drawings as examples and described in detail herein. It should be clear, however, that the intention is not to limit the embodiments to correspondingly disclosed forms, but that the embodiments are intended to cover all functional and / or structural modifications, equivalents and alternatives falling within the scope of the invention form.

[0046] A transmission used for transmitting power, for example in a vehicle, may be partially filled with transmission oil for lubrication and for cooling.

[0047] Especially in transmissions used in vehicles, the longitudinal accelerations that occur, for example, during braking and acceleration of the vehicle can cause transmission oil to divert to shock absorbers arranged in th...

Abstract

The invention discloses a damper arrangement for motor vehicle drive train, wherein the damper arrangement includes a damper (120) for damping torsional vibrations and a rotationally fixed fluid guide element (110), wherein the fluid guide element (110) is axially adjacent to the damper (120), wherein the fluid guide element (110) has at least one duct (112-1, 112-2, 112-3) arranged and designed to convey a fluid at least partially surrounding the damper (120) into the duct (112-1, 112-2, 112-3) through the rotation of the damper (120); and a motor vehicle transmission having such a damper arrangement.

Description

technical field [0001] The invention relates to an assembly of a shock absorber and a fluid guiding element in a power train of a motor vehicle. The invention also relates to a transmission with such an assembly. Background technique [0002] In a motor vehicle powertrain, a shock absorber may be used to damp torsional vibrations generated by the combustion engine of the powertrain. For this purpose, speed-adaptive dampers are used, for example. The shock absorber may be an integral part of a transmission arranged between the combustion engine and the driven wheels in the power train of a motor vehicle. Such transmissions are usually partially filled with transmission oil for lubrication and cooling. During braking and downhill driving, transmission fluid can be pushed from the sump to the rotating damper. Here, the transmission oil can be foamed and / or turbulently picked up by the shock absorber. [0003] This can result in the formation of oil foam and increased splas...
