Pivotal connection for use in actuator for transmission of rotational torque, has coil springs that are in frictional engagement with respective friction surfaces during rotation of driven section in respective directions

摘要

#CMT# #/CMT# The connection has a drive part (1) and a driven section (2), where the drive part and the driven section are rotatable in relation to a frame-fixed element. A positive connection is provided between the drive part and the driven section. A set of friction surfaces is arranged in an axial manner. A coil spring (3) is in frictional engagement with one of the friction surfaces during rotation of the driven section in one direction. Another coil spring (4) is in frictional engagement with another friction surface during rotation of the driven section in another direction. #CMT# : #/CMT# An independent claim is also included for an actuator. #CMT#USE : #/CMT# Pivotal connection for use in an actuator (claimed) for transmission of a rotational torque. #CMT#ADVANTAGE : #/CMT# The coil springs are in frictional engagement with respective friction surfaces during rotation of the driven section in respective directions, thus allowing the pivotal connection to work in a reliable manner, while providing smaller switching cycles for the connection, and reducing noise. The drive part and the driven section are arranged in a compact manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of a pivotal connection. 1 : Drive part 2 : Driven section 3, 4 : Coil springs 15 : Housing 16 : Housing part.
