Abstract

The invention relates to a cone ring transmission unit having two cone friction wheels (2, 3) that are arranged opposite to each other. A friction ring (8) stays in contact with the two cone friction wheels (2, 3) and rounds at least one (2) of them. A contact surface (16, 19) having at least a cone friction wheel(2, 3), and at least a contact surface (12, 13) of the friction ring (8) comprises transverse grooves (24). The grooves extend at a certain angle transverse to the direction (22) of rotation of the cone friction wheel(2, 3) and / or the friction rings (8).

Description

technical field

[0001] The invention relates to a conical ring transmission having two conical friction wheels arranged opposite to each other and a friction ring interacting with the two conical friction wheels and surrounding one of the conical friction wheels. Background technique

[0002] DE 195 42 726 A1 discloses a conical ring transmission in which conical friction wheels arranged opposite one another are arranged on parallel shafts. By moving the friction wheel in the axial direction of the shaft, the transmission ratio of the cone ring transmission can be adjusted steplessly.

[0003] The friction ring on a cone ring transmission has a rotating, outwardly working outer contact surface and a rotating, radially inwardly working inner contact surface. The inner contact surface here forms the first contact area with the contact surface of the conical friction wheel surrounded by the friction ring, which contact surface of the conical friction wheel is the conical outer...
