A shaft (W) for a motor vehicle transmission (G) includes four axial bore holes (B, B, B, B) for conducting fluid within the shaft (W). A central axis of each of the four bore holes (B, B, B, B) is spaced apart from an axis of rotation (WA) of the shaft (W). A radial distance (r) between the central axis of at least two of the four bore holes (B, B, B, B) and the axis of rotation (WA) differs from a radial distance (r) between the central axis of one of the remaining bore holes and the axis of rotation (WA). A transmission (G) for a motor vehicle with a shaft (W) is also provided.

Shaft for a motor vehicle transmission

A transmission for a motor vehicle includes a housing and a gear set. An oil drainage channel is formed by the housing and/or by an element connected to the housing and is arranged spatially underneath the gear set. The oil drainage channel includes at least one gear set-side inlet port, a closed underside, and an oil sump-side outlet port at one end of the oil drainage channel, which are designed and arranged in such that oil from the gear set enters the oil drainage channel through the at least one inlet port and is guided along the closed underside to the outlet port. A suction port of a hydraulic unit of the transmission is arranged in the oil sump spatially underneath the closed underside of the oil drainage channel and axially offset with respect to the outlet port.

Transmission for a motor vehicle

An arrangement of at least one sensor track-scanning rotor position sensor (A) of an electric machine (EM) in a hybrid transmission housing () that includes a torque converter () and a housing-affixed oil supply plate arrangement is provided. The rotor position sensor (A) is attached on an oil-supply-plate side, and a sensor ring (), as a sensor track, is attached on a converter side. A hybrid transmission housing () including the arrangement is also provided.

A shaft (W) for a motor vehicle transmission (G) may have axial bore holes positioned within the shaft and configured to guide fluid within the shaft. The shaft may have first, second, and third axial sections (W, W, W), the second axial section being axially between the first and third axial sections. Fluid enters the axial bore holes in the second axial section and exits the axial bore holes in the first and third axial sections. One of the axial bore holes (B; B, B) is arranged, at least partially, in the first axial section and is radially spaced from an axis of rotation (WA) of the shaft. Another of the axial bore holes (BRS; B_SE, B) is arranged, at least partially, in the third axial section. The one of the axial bore holes (B; B, B) is coaxial with the other of the axial bore holes (BRS; B_SE, B).

Transmission shaft, transmission, and motor vehicle drivetrain

A transmission device () has a double-flow sliding vane pump (). Hydraulic fluid is supplied to suction sides (A,B) of the pump () through an inlet area () from a hydraulic fluid reservoir () and from a suction loading () via an annular chamber () and pump inlets (). The annular chamber () is delimited by the cam ring () and a housing () enclosing the cam ring (). A sealing gap () extends in the circumferential direction (U) between one of the pump inlets () and a circumferential area () of the cam ring () delimiting the inlet area () from the hydraulic fluid reservoir (). Courses () of the inlet area () and of the suction loading () installed in the transmission device () respectively form a first angle (&#x3b1;) and a second angle (&#x3b2;) with the vertical axis () of the transmission device ().

Transmission with double-flow sliding vane pump

A gearbox comprising a gearbox housing at least partially surrounding a cavity, an oil sump connected to the gearbox housing and surrounding another cavity, and a separating element separating the cavity from the other cavity and having a passage through which oil located in the cavity is fed into the other cavity. The passage is arranged in a plane at an intersection line between a first oil level upper side and a second oil level upper side. The oil is fed from the cavity into the other cavity exclusively through the passage. The separating element has a passage section and a separating section, the passage section protrudes from the separating section in the radial direction.

Transmission

A planetary transmission includes a planetary gear set (), another planetary gear set (), a fluid line () through which fluid is flowable to the planetary gear set () and to the other planetary gear set (), and a fluid collecting device () which is in fluid communication with the fluid line (). The fluid collecting device () is connected in a rotationally fixed manner to the planetary gear set (). The fluid collecting device () is configured for dividing the fluid from the fluid line () which has flowed into the fluid collecting device () into a fluid part which is flowable to the planetary gear set () and another fluid part which is flowable to the other planetary gear set ().
