Multi-part pendular rollers for centrifugal force pendulum device in powertrain of combustion engine-driven motor car, have roller surfaces rotatable around rotational axis, and bearing provided between bodies and axles

摘要

The rollers (25, 26, 35, 36) have a pendulum mass carrier part (2) comprising a set of roller bodies with respective roller surfaces and another roller body with another roller surface that is arranged in an extending direction of a pendular roller rotational axis between the set of roller surfaces. The roller surfaces are rotatable relative to each other around the rotational axis. A bearing i.e. slide bearing, is arranged between the roller bodies and axles, where the roller bodies are independently and rotatably supported on the axles. An independent claim is also included for a centrifugal force pendulum device.
