Embracing gear with two pairs of friction plates - has chain or belt engaging in friction plates with defined force transmission and adjustment of axially displaceable friction plate via control device

摘要

The friction plates (7) via a toothing (19) consisting of pins (35) in the one plate and corresp. openings in the opposite plate with a support plate (9) axially displaceable on the shaft (5) and under spring tension are joined to one another with the formation of a gap (11). On the periphery (12) between the support plate and the friction plate a common wedge-shaped ring groove (16) is formed, in which a wedge-shaped ring (16) engages. The wedge-shaped ring is adjustable in the ring groove (15) via a control device (17) in a specific direction (18,19) so that the displaceable friction plate is pivotable in relation to the fixed friction plate (6) in an axial inclined position, and a receiving gap (A) is formed, the width of which in a peripheral direction narrows or widens. ADVANTAGE - The transmission between the cone plate pair provides a defined favourable force transmission over the largest possible angle area of the friction plates.
