Embodiment Construction

[0034] figure 1A detailed sectional view of a transmission G for a motor vehicle according to a first embodiment is shown. The transmission G has a plate clutch B that acts as a brake. A section of the housing GG of the transmission G is used here as the outer disk carrier ALT of the multi-disk clutch B. The outer linings AL, ALE are arranged axially displaceable on the outer lining carrier ALT. On its outer diameter, the ring gear HO of the planetary gear set of the transmission G forms the inner disk carrier ILT of the multi-disk clutch B. The inner lining IL is arranged axially displaceably on the inner lining carrier ILT. The inner friction plates IL and the outer friction plates AL, ALE are arranged alternately. The inner lining IL is designed as a lining friction lining. The outer friction linings AL, ALE are designed as lining-less friction linings. On one side of the multi-disk clutch B is arranged a piston K which can be displaced in the direction of the multi-...

Abstract

The invention relates to a plate clutch (B) for wet operation of a motor vehicle transmission (G), in which a piston (K) is arranged on a first side of the plate clutch (B), by means of which a force acting in the axial direction can be exerted on friction plates and outer friction plates (IL, AL) in order to close the plate clutch (B), wherein the plate clutch (B) is supported on the contact surface (AF) on a second side opposite the first side by means of an end friction plate (ALE) of the outer friction plate (AL), and wherein grooves (N) are provided on the contact surface (AF) and / or on the end friction plate (ALE), the grooves being designed and arranged such that a cooling fluid (O) supplied to the plate clutch (B) can flow out of the plate clutch (B) through the grooves (N); the invention further relates to a transmission (G) for a motor vehicle having such a plate clutch (B).

Description

technical field [0001] The invention relates to a wet-running multi-plate clutch for a motor vehicle transmission and to a motor vehicle transmission having such a multi-plate clutch. Background technique [0002] EP 0 822 350 A2 describes a wet-running multi-plate clutch. In this case, the friction elements are alternately connected to the outer element and the inner element. The friction elements are axially displaceable and can be brought into frictional contact with each other by applying an axial force. According to EP 0 822 350 A2, in Figure 6 and Figure 7 In the embodiment shown in , the multi-plate clutch is supplied with lubricating oil from radially outside via channels. In the disengaged state of the multi-plate clutch, lubricating oil can flow out via the gap between the last outer friction plate and the support disk. A wave spring is arranged in the gap, which keeps the gap open in the disengaged state of the multi-plate clutch. When the multi-plate clutc...
