- Temperiermediums in particular a cooling fluid, in particular by a disk set of a multi-plate clutch, are slowed down by the temperature control medium or the cooling fluid or cooling oil is decelerated.
- the decelerated tempering medium can absorb heat over a relatively long period of time in order to dissipate this heat from the friction surface or from the friction surface and from a counter surface in a disk pack. As a result, the cooling performance can be improved.
- the groove is also referred to as Temperiermediumnut ordeölnut.
- the groove is preferably provided in a friction plate of a multi-plate clutch. If necessary, the groove can also be provided in a steel plate of the multi-plate clutch.

- Brake flows preferably the tempering medium from the inner periphery of the friction surface through the groove with the stepped course to the outer circumference of the annular surface.
- a further preferred embodiment of the friction surface is characterized in that a plurality of grooves with a stepped course are distributed uniformly in a circumferential direction. As a result, the temperature control is further improved.
- a further preferred embodiment of the friction surface is characterized in that the groove is delimited by the stepped course of two step-step-like Nutbegrenzungslinien.
- the staircase-like Nutbegrenzungslinien can also be referred to as stair lines. Through these stair lines, the groove, viewed in plan view, bounded laterally. In depth, the groove is bounded by a groove bottom.
- the tempering medium can be braked particularly effectively during operation of a clutch and / or brake device equipped with the friction surface by means of the step-step-like groove boundary lines.
- a further preferred embodiment of the friction surface is characterized in that the step-step-like Nutbegrenzungslinien, based on the friction surface, radially inwardly define an input of a Temperiermediumkanals.

- a further preferred embodiment of the friction surface is characterized in that the input of the Temperiermediumkanals is bounded by two radially extending line sections.
- the term radial refers to an axis of rotation of the friction surface during operation of a clutch and / or brake device equipped with the friction surface.
- Another preferred exemplary embodiment of the friction surface is characterized in that a vertical line segment is angled away from the radially extending line sections.
- the subsequent line sections are arranged to represent the stair-step-like course or stepped course of the groove in each case alternately radially and perpendicular thereto to the outer circumference of the annular surface.
- a further preferred embodiment of the friction surface is characterized in that an output of the Temperiermediumkanals, relative to the friction surface, radially outward in the circumferential direction offset as far as the entrance of the
- Temperiermediumkanals is arranged so that the input and the output of Temperiermediumkanals do not overlap in the circumferential direction. This further improves the cooling performance.
