Problems solved by technology

On the other hand, a high oil volume flow leads to drag torque and thus to undesired losses
The efficiency of the transmission is negatively affected by splash losses
Active oil injection systems, such as dry sump lubrication through oil pumps, can prevent this effect, but require increased effort, such as additional components and control technology

Embodiment Construction

[0051] Figures 1 to 6, which are described together below, show a drive assembly 2 according to the invention for a drive train of a motor vehicle. In the present embodiment, the transmission assembly 2 comprises: a first gear arrangement 3, which can also be designated as a transmission and is designed in particular in the form of an angle transmission; a second gear arrangement 4, which is arranged downstream in the power path , which is optional and is designed here in the form of a differential transmission; and a clutch 5, which is drivingly connected to the first gear unit and the second gear unit, respectively, and is designed for the clutch input portion 6 and the clutch Variable torque transfer between output sections 7. An actuator 8 with an actuating element 9 is provided for controlling the clutch 5 , which acts on the clutch 5 to adjust the torque transmittable between the clutch input part 6 and the clutch output part 7 .

Abstract

The invention relates to a drive assembly for a drive train of a motor vehicle, comprising: a transmission (3); a clutch (5); an actuator (8) for controlling the clutch (5), wherein the actuator (8) comprises an actuating element (9) acting on the clutch (5) to set a transmittable torque; a housing (10) having a transmission receiving chamber (13), a reservoir (14) and a clutch receiving chamber (15), in which lubricant is delivered from at least one of the transmission receiving chamber (13) and the clutch receiving chamber (15) into the reservoir (14) due to rotational movement during operation; a valve (19) for controlling the flow of lubricant from the reservoir (14) to the transmission receiving chamber (13) and/or to the clutch receiving chamber (15), the valve (19) being operativelyconnected in a manner to the actuating element (9) of the actuator (8), the valve (19) opens when the clutch (5) is actuated and closes when the clutch (5) is not actuated.

Description

technical field [0001] The invention relates to a transmission assembly with a transmission and a controllable clutch and oil injection system, in particular for a drive train of a motor vehicle. In a drive train, a transmission assembly or arrangement comprising a transmission and a controllable clutch is used for power transmission between several transmission components such as a drive shaft and / or a drive gear. They enable the transmission of rotary motion, variable torque transmission and / or connection or disconnection of drive trains. Background technique [0002] Such transmission assemblies including clutches are used, for example, in the drive train of a multi-axle driven motor vehicle, in particular in a drive train with a permanently driven first drive axle and an optionally driven second drive axle. Such transmission concepts with transaxles that can be selectively driven on demand are also referred to as hang-on, on-demand or disconnect systems. [0003] A pow...
