There is provided an indicator system for a torque limiter. The system comprises a first component extending around an axis (A) and comprising one or more radially extending cam surfaces, and a second component in combination with a third component. The third component is fixed against rotation relative to the second component, but is axially movable relative to the second component. The third component comprises one or more notches, each receiving one of the radially extending cam surfaces. Upon relative rotation between the first component and the combination of the second component and the third component, a surface of each of the notches is configured to ride up a corresponding cam surface of the first component, causing the third component to move axially away from the second component.

Drive arrangement

A drive arrangement for adjusting an aerodynamic flap on a vehicle. The drive arrangement includes an electric motor, a spur gear mechanism having gear stages, an output shaft, and at least two housing halves. The spur gear mechanism includes at least one self-locking gear stage that does not form the first gear stage nor the last gear stage of the spur gear mechanism. A safety coupling is arranged between the self-locking gear stage and the output shaft to disengage the output drive on overload in order to protect the flap attached thereto from damage.

Overload clutch

The disclosure relates to an overload clutch, comprising a cylindrical clutch housing having a housing body and a housing cover, and comprising two clutch elements arranged within the clutch housing, via which a drive movement is transmissible in an engaged state, wherein the clutch elements, for transmitting the drive movement in the engaged state, are engaged with each other in an interlocking and/or frictional manner and, can be brought out of engagement when an overload occurs. The housing body comprises a plurality of engagement elements, and the housing cover comprises a plurality of retaining structures corresponding to the engagement elements, wherein the engagement elements are able to be brought into engagement with the retaining structures by rotating the housing cover relative to the housing body.

Electric retractable view device for vehicle, and shaft outside-fitting gear incorporated in the device

Solving a problem in strength that occurs as a result of forming a shaft outside-fitting gear for an electric retractable view device for a vehicle, using a material including a resin as a base material. A shaft outside-fitting gear is formed of a material including a resin as a base material. The gear includes a clutch surface in one end face in an axis direction thereof. The clutch surface is disposed on an inner circumferential side and an outer circumferential side of a radial position of a tooth bottom of each gear tooth of the gear relative to the radial position of the tooth bottom, in a radial direction of the gear. One end face in the axis direction of the gear has a structure in which a valley of each gear tooth of the gear is occluded at a radial region at which the clutch surface is disposed.

SEALED ACTUATOR WITH INTERNAL CLUTCHING

A sealed actuator with internal clutching assembly including an output shaft, output detent ring, moving detent ring, and a wave spring, which is fit inside a sealed housing. The moving detent ring is able to move axially to the output shaft and the output detent ring is able to rotate on the output shaft. Intermeshing ramped teeth of these rings are held together by a wave spring and allow the output shaft to rotate and transmit torque of a motor through a main gear operably coupled to an output gear mounted on the output shaft to the outside of the housing. During predetermined high loads, the output and moving detent rings ramped teeth create an axial force that overcomes the load from the wave spring, which allows moving detent ring to disengage and output shaft to rotate freely to help prevent damage to the actuator.

OVERRUNNING CLUTCH HAVING A FRICTION-INDUCED ACTUATING FORCE

The invention relates to an overunning clutch, comprising a torque-introducing clutch element, a torque-receiving clutch element and switching element, which is forced from an engagement position into a freewheeling position or from a freewheeling position into an engagement position in dependence on the direction of a sufficient change in the rotational angle position between the torque-introducing clutch element and the torque-receiving clutch element by means of an actuating force applied to the switching element by an actuator. According to the invention, the actuating force is a friction-induced actuating force, which is induced by means of a friction-force pairing between the actuator and a component of the overrunning clutch that is in frictional contact with the actuator and the actuator forms an interlockingly acting actuating stop, by means of which the actuating force acts on the switching element.
